55SWF4KB9FU0597172015 MERCEDES-BENZ C-Class4-MATIC

I was driving my car was sputtering or trying to shut off while I press the gas and I let go of the gas and it catches and stayed on. I took it to the dealership and they said they found nothing wrong. May 3rd around 12pm im driving on the freeway and as im getting on the express lane going 60 it dies and I couldn't move the steering wheel and I slammed into a guardrail. After doing research my car (vin [XXX] ) had multiple recals from the fuel pump and steering wheel and the dealership never fixed or checked any recalls before selling it to me.

Component/System Failure: The rear subframe on my 2015 Mercedes-Benz C300 failed due to severe corrosion/rusting. The subframe is available for inspection upon request. Safety Risk: This failure created a serious and immediate safety hazard. While driving at highway speeds, the structural integrity of the vehicle was compromised, I had to break and lost control of the vehicle and almost causing a crash. This also posed a danger to other drivers on the road. The condition was severe enough that I believe I narrowly avoided a major accident. Confirmation of Problem: The issue has been confirmed by a Mercedes-Benz dealership service department, who identified the subframe as rusted and structurally compromised. Inspection by Other Parties: The vehicle has been inspected by a Mercedes-Benz dealership. It has not yet been inspected by the manufacturer directly, police, or insurance representatives. Warning Signs Prior to Failure: There were no clear warning lights or dashboard messages indicating this issue prior to the failure. The problem appears to have progressed without visible warning until it became severe. Additional Context / History: Mercedes-Benz has acknowledged subframe corrosion defects in certain vehicles from approximately 2010–2020, but my specific vehicle was not included in the extended warranty coverage. This is the second Mercedes-Benz vehicle I have owned (previously a 2012 model) that has experienced the same subframe failure. I was previously told that this issue had been resolved in newer models, which influenced my decision to purchase this vehicle. Additionally, this vehicle was purchased as a Certified Pre-Owned Mercedes-Benz, which implies it passed a detailed inspection process. Despite this, a major structural component failed. A warranty claim was submitted but denied on the basis of “rust,” even though this appears consistent with a known factory defect.

rusted rear subframe. unsafe braking and suspension due to this. damage code 35441 47 shows 2008-2015 vins but my vin does not show active recall, yet has the issue

The rear of the car would begin to slip during turns and when brakes were applied. When I had the issue checked out, my mechanic said that the rear subframe has severe corrosion, rust and holes. The subframe perforation is causing instability in the rear wheels, which is a safety issue. I took the car to Mercedes for an inspection and they confirmed the holes in the sub frame,with the inspector stating that the sub frame is "about to fall off". I believe this to be a safety issue as having the wheels or subframe fall off could cause fatalities. This appears to be a manufacturing defect given recalls for the same issue in other models of the 2015 c300.

Mercedes issued a recall for Mercedes C class for the model year up to 2015 for rear subframe that is rusting with holes in it. The dealer tells me my car is not covered by Mercedes even though it is a 2015 model. They gave me an estimate for the repair of over $5000. They say the model changed mid 2015 and mine is a model that is not covered. This could cause a serious crash at high speed. I am not sure why that repair is not covered for my 2015 model & I would like Mercedes to honor the repair.

The contact owns a 2015 Mercedes-Benz C300. The contact stated that while driving at an undisclosed speed, there was an abnormal sound coming from the vehicle. The vehicle was driven to the shoulder of the road. The contact inspected the exterior of the vehicle and became aware that the moon roof panel had detached, and the moon roof panel flew off the vehicle. The dealer was made aware of the failure. The contact stated that the vehicle was previously repaired under NHTSA Campaign Number: 21V197000 (Structure) in 2021. The contact was informed that the repair was not covered under warranty. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The manufacturer was made aware of the failure but provided no assistance. The failure mileage was approximately 62,612.

Exhaust camshaft pulse wheel shifted on camshaft. Replacement of camshaft, positioner, oil control valve, timing chain and chain tension was recommended.

The R&R rear subframe is showing premature corrosion that can cause structural failure. This can lead to rear suspension detachment, erratic driving behavior, and severe safety risks. This problem has been confirmed by the Mercedes Benz dealer. This has been inspected by the Mercedes Benz dealership. There were no warning lamps, messages or other symptoms of the problem prior me finding out it was failing. I had a multi inspection performed on my car due to another issues and the MB service dept found it during that time. Which means if I had never had the multi inspection done due to another issue I was having with the car, I would not have known.

Rear subframe has rust and holes. Dealer is saying not covered under warranty and asking for 8000

When buying this car from Auto Shoppers, they was an airbag light on but dealership said it was a sensor from auto detail on car or recall. Got diagnostic from Mercedes Benz, findings was there was no air bag in place on drivers side. Dealership did not tell us there was no air bag and only was a sensory/recall and are refusing to fix it.

Rear subframe rotted, hole like perforation on the frame. The current extended warranty covers the C204, but my Mercedes C300 2015 has a C205 that is the same part number, but for some reason the warranty does not cover the C205, but has the same identical issues as the C204.

I am reporting a structural failure of the rear subframe due to corrosion on my 2015 Mercedes-Benz C300 4MATIC. The failure was diagnosed by an authorized Mercedes-Benz dealer, who confirmed that the rear subframe has corroded and broken, compromising the structural integrity of the vehicle. This is not cosmetic rust. The subframe is a load-bearing structural component, and its failure creates a serious safety risk, including potential loss of vehicle control. I have been advised that the vehicle may be unsafe to operate in its current condition. The vehicle has approximately 143,000 miles and has been registered and operated in Connecticut, a salt-use state. However, this level of corrosion leading to structural failure of a major suspension component is premature and not consistent with normal wear and tear, even in such environments. I contacted Mercedes-Benz USA and escalated the matter to an Executive Referral Manager. Mercedes-Benz acknowledged the seriousness of the issue but declined to provide any repair assistance, stating that my vehicle falls outside of warranty extension and goodwill parameters. Mercedes-Benz did not dispute the nature of the failure or its safety implications, but refused to address the issue based solely on internal policy criteria such as age and mileage. A rear subframe supports critical suspension components. Corrosion leading to structural breakage can result in instability, misalignment, or failure of suspension components while driving, increasing the risk of a crash. This issue appears to be consistent with known reports of rear subframe corrosion in similar Mercedes-Benz vehicles, raising concern about a broader safety defect. The failure was identified during inspection, and repair costs are estimated at approximately 5,000–6,000. I am submitting this complaint due to the safety risk posed by structural failure and the manufacturer’s refusal to address the issue.

The rear subframe completely rusted out on both sides causing the car to swerve very dangerously to the left when braking. The subframe was diagnosed by the dealer. There was a " collision prevention assist inoperative" warning a week prior the the car noticeably swerving when braking

REAR SUBFRAME RUSTED OUT AND BROKEN

The contact owns a 2015 Mercedes-Benz C300. While driving approximately 15 MPH, the brake pedal was depressed, and the body of the vehicle shifted to one side. The vehicle was drivable after the failure. There was no warning light illuminated. The vehicle was driven to the residence and parked. The contact stated that due to the failure, the vehicle was unsafe to drive. An independent mechanic was contacted, and it was determined that the rear subframe was corroded. The vehicle was not repaired. The manufacturer was notified of the failure, and it was confirmed that the VIN was not under recall. The failure mileage was not available.

Fuel pressure pump hose on top of the engine leaks gasoline this is a serious safety concern the hot engine can catch fire easily, I noticed due intoxicating vapors in cabin while driving because car takes air from q side of the engine to the cabin. The car only has 28k miles on it.

After strong fuel odor in interior of car, inspected the engine and discovered fuel in the top of the engine this is a serious safety concern due possible car fire. The leak appear to be due failure of a top engine gasoline hose due low quality. The car barely has 30k miles .

I have been informed by my dealer's service unit that the rear subframe of my car (2015 Mercedes C class) is rusted with holes. My understanding is that this can affect the integrity of the structure and cause problems while driving. According to your website [XXX] ) , this should be covered under a warranty extension. However, Mercedes says that my car is not, and to fill out this form if I believe it should be. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

1. What component or system failed or malfunctioned? The low-pressure fuel feed line (Part No. 274-070-35-00) and its associated clamps connected to the high-pressure fuel pump. Availability: State: The defective hose is currently on the vehicle and is available for inspection. If the repair proceeds, I request the dealership to retain the failed part for my inspection. 2. How was your safety or the safety of others put at risk? The failure resulted in raw fuel leaking directly into the engine compartment. This creates an immediate and severe fire hazard, as gasoline is being released near high-temperature engine components. Furthermore, the strong odor of gasoline entered the cabin through the HVAC vents, exposing passengers to toxic fuel vapors while the vehicle was in operation. 3. Has the problem been reproduced or confirmed? Yes. The defect was confirmed by Mercedes-Benz of Orange Park (Dealer Code: 64111). The technician performed a 'cold start' inspection and verified fuel leaking from the low-pressure line to the high-pressure pump. > Note: My service advisor's admitted: Yes sir we will do the hose. 4. Has it been inspected by the manufacturer, police, insurance, or others? Answer: The vehicle has been inspected and the failure documented by an authorized Mercedes-Benz dealership technician. It has not yet been inspected by insurance or police as no fire has occurred yet; however, the dealership has identified the part as defective. 5. Were there any warning lamps or other symptoms prior to failure? There were no warning lamps or dashboard messages. The primary symptom was a pungent smell of raw gasoline inside and outside the vehicle, specifically during cold starts. These symptoms first appeared recently [January 3rd, 2026] and became persistent as ambient temperatures dropped.

Strong gas odor coming from vent when heat and AC is on. Odor was causing dizziness and had to drive with window open or vent off. When opening the hood gas odor was also present. Brought to the mechanic and found fuel lines leaking. Went online and found out this is a very coming problem. I had to spend $657. to repair. Mechanic stated Mercedes issued a service bulletin but not a recall.

Failed/Malfunctioned Component: Rear subframe (structural/chassis component) exhibited advanced corrosion (perforation/rust-through), compromising structural integrity and alignment/handling. Availability for Inspection: Yes. The vehicle and the subframe are available for inspection upon request. I can provide photos, videos, and repair estimates if needed. The corroded subframe is fracture and detach suspension mounting points, which may lead to: Sudden loss of vehicle stability or control (especially during braking, cornering, or over bumps). Unpredictable alignment changes causing pulling, vibration, or abnormal tire wear that can escalate into a loss-of-control event. Increased stopping distance and potential for wheel misalignment or collapse, raising the risk of a crash involving occupants and other road users. I limited driving/use due to the risk; issue is a structural safety concern rather than cosmetic. Confirmation: Yes on multiple visits since Oct 2023 -Yes—diagnosed and documented by Mercedes-Benz of Silver Spring on Oct 2 2023, Nov 2023 and Dec 2025. Technician confirmed severe corrosion/rust perforation on the rear subframe requiring replacement. No No

Purchased this car in September 2024 for our [XXX] son. Upon inspection at our local Mercedes Dealership on December 1, 2025, we were informed that the rear subframe should be immediately replaced as there is a rusted hole in the subframe, "compromising the structural integrity of the rear of the vehicle." We were informed that the prior bulletin issued for 2010-2014 C-Class models did not include our 2015 C-Class. We were quoted over $5200 to repair the subframe. There were no warning messages, lights problems that were noted, prior to inspection. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Fuel hose system leaking. Inhalation of gas fumes caused headaches and nausea. Risk of vehicle fire. Yes, the problem has been confirmed by a Mercedes dealer. This is a known issue with Mercedes C300 2015 models and other years. There have been other complaints/lawsuits against Mercedes not wanting to pay for the issue. No warnings just strong gas smell.

I took my car for service and they found a rusted rear subframe, with a small hole in it. I was informed that the car was not safe for my annual trip from NJ to FL (about 1000 miles). I was also told that this defect was a recall for cars through 2014. My car is a 2015 and I have the same defective part - which is supposed to be manufactured with rustproof material. I am requesting that this car be recalled and the part replaced by the manufacturer.

The car suddenly glitched and locked itself—with my dog, my purse, my phone, everything—inside on an extremely hot day. There was no one around, and it was terrifying. I had opened the passenger door for my dog to climb in, and as I walked around to the driver’s side, the doors somehow locked on their own. Panic set in immediately. My dog, my phone, and my purse were all inside, and I had no way to call for help. We had just finished a walk, and then this happened out of nowhere. I had to run around searching for someone who could help. Eventually, I found a stranger who called the police, and they had to break the door open because it was over 100 degrees outside. I was terrified my dog would pass out from the heat. There were no warnings, no alerts, no messages. If it weren’t for that random stranger who happened to be there and willing to help, I don’t know how I would have gotten my dog out. It’s a reminder of the kindness of strangers, but the glitching car was truly terrifying and not ok.

My car’s rear subframe was so badly disintegrated due to severe corrosion. It made the driving so dangerous when braking and nearly caused an head-on collision. I have reported this issue under tracking number 11701609 and would like to provide pictures on the corrosion issue.

My wife first noticed loud noise from the back of the car when braking. Subsequently, when I drove it one day after, the car lost balance and nearly went into the opposite direction of the road on a two-lane street. The MB dealership later confirmed the problem was a severely corroded rear subframe that needs to be repaired at very significant expense. This is a serious safety issue that could have caused a head-on collision for me and my wife as a passenger on that occasion. I believe this issue warrants a full investigation by the NHTSA. I understand other Mercedes models such as the 2008-2015 C300 (W204) had the same corrosion issue and was under a recall but my car model (W205) was not covered by this recall. Thank you for your attention to this matter. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Rear subframe rusted out, car is not safe to drive

Rear subframe completely rusted out. While driving on the hwy I heard a loud noise, a couple minutes later I hit the brakes to slow down to get off my exit and after pressing the brakes the car instantly fishtailed sending me sideways across 2 lanes of traffic. Luckily no one was injured or killed. I’ve seen that the car manufacturer was replacing this issue on models 2008-2015. My vehicle is a 2015 and they are telling me my vehicle is not covered for the issue. The car is not drivable and Mercedes needs to be held accountable. A critical component such as rear subframe completely rusting out in just under 10 years is unheard of and I can’t afford to pay 10k to fix it. Please help

I’m the owner of a Mercedes Benz C- Class Sedan 2015. My Rear Sub Frame Rusted Through at The right trailing arm - Fails state inspection. Mercedes Benz has issued a extended 20 year warranty on all vehicles from 2008 - 2015 C - Class Sedan for Rear Sub Frame that rusted out. Mercedes Benz service advisor stated that my vehicle was not under that extended warranty when he run my vehicle Vin number. My vehicle should be under that warranty, I have the same problem with the same vehicles on the list. Please help. Thank you

The Rear Subframe on this vehicle is rusted and has hole in it. The sub frame requires replacement. The sub frame was inspected by the Mercedes-Benz Dealership, Euro Motorcars in Germantown, MD and they recommended that the sub frame should be replaced. There is an extended warranty that has been issued by Mercedes-Benz for the Model Year and Model (2008-2015 C-Class Sedan/Coupe). However, Mercedes-Benz decline to cover the cost of the repair stating that my VIN is not part of that Warranty. This is a well documented safety issue and I believe that Mercedes-Benz should include my VIN in that extended warranty and replaced the subframe on my car.

I took my 2015 vehicle to the Mercedes dealership and learned the rear subframe is rusted and has holes on two sides. I was warned that it is a safety hazard and could lead to a lack of control and other dangerous situations. I also learned that other 2010 through 2014 Mercedes models in the same class have been recalled for this exact concern. I am disappointed and upset to learn that those concerns are known, but not addressed in this model and put customers at risk.

there is a recall for 2008-2015 Mercades Benz c-300 c/w204. this recall talks about the rear subframe rusting out early on this car. we have a 2015 c300 c/w205. this car is seeing the same early rust seen in the other c-300. the dealership is refusing to do right by the warranty because it is a c/w205 even thought this is a known problem for this year and type of car. I am making this because it should be extended to all c300 2008-2015 cause they all use the same subframe. they changed the subframes and the look of the c-300 starting in 2016. it also would appear that the rust is coming from the inside of the subframe making we wonder how bad it is on the inside if it is making its way to the outside of it. I believe water penetrates into the rear subframe has no drainage and begins to rust. also we take the car to the dealer every 5 Ish months and this last service is the first we have seen of this.

The contact owns a 2015 Mercedes-Benz C300. The contact stated that upon taking the vehicle for the State Inspection, the contact was informed that the rear subframe was rusted, and there was a hole on each side of the rear subframe.

On January 21,2025, I had an appointment for an inspection at Mercedes Benz of Smithtown, the dealership I use. I was informed that my car required replacement of a rotted rear subframe. A hole had rotted through, causing the car to "Fail inspection and was NOT SAFE" to drive. I was provided a video showing the damage. There was a recall in effect however, my Vin # was not included and it’s status has not changed. The 2015 C-Class Sedan/Coupe Vin # [XXX] , which was neglected to be included in the recall covers 2008-2015 C-Class Sedan/Coupes, regarding rotted rear subframe. MBUSA extended the vehicle Warranty 4 yrs/ 50,000 miles to 20 yrs/unlimited miles. However, I do not qualify for reimbursement of $4,014.92, because my Vin # was left off the list. Mercedes customer assistant center states they can't help, has to be included by NHTSA, when I said they cannot add a Vin #. I was then told, it has to come from the head office in Germany.

Failed component: Front Sunroof Clip What component or system failed or malfunctioned, and is it available for inspection upon request? Sunroof clip, yes. How was your safety or the safety of others put at risk? The glass pane lifted while the car was in motion and had to be held down to secure it until the car stopped. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No While merging to enter the freeway at approx 45-50 mph I opened my sunroof. At about halfway back the glass began to lift up off the track/railing as if it was going to fly off the track. Had I not been holding the button to open the sunroof I would not have noticed and the entire glass pane would have blown off, possibly damaging the car or worse flying off and hit another car. I had to hold the glass in place to keep it from flying off until I was able to exit the freeway. Once I stopped the car to inspect the sun roof I noticed the clip that secures the glass to the track was broken (crumbled) in the sunroof track. I removed the pieces of broken plastic from the track and was then able to close the sunroof. I am now unable to safely open my sunroof while the vehicle is in motion.

Rear-subframe corrosion at the lower-control-arm mounts has progressed to the point where both arms have play and produce loud metallic bangs while braking or turning at low speed. Two independent shops lifted the car, documented flaking rust around the bushing sleeves, and advised the subframe is structurally compromised and could let a control arm detach under load. The corroded subframe remains installed and can be inspected on request. Safety risk: a detached rear control arm would cause sudden, unpredictable steering and loss of control. The vehicle already pulls right under braking, and feels very unstable in curves Problem has been reproduced and photographed by two independent repair facilities. No manufacturer representative has inspected the vehicle so far. Additional component failures possibly linked to the same progressive chassis stress: premature wear of both front CV axles; timing-chain stretch with worn guides; slack oil-pump chain; upper & lower oil-pan gasket leaks; water-pump seepage; right engine-mount collapse; persistent misfire traced to a loose intake-hose clamp; transmission-cooler hose clip released under pressure, dumping all ATF and destroying the automatic transmission; excessive play in all four lower control-arm bushings. The transmission and the other components were replaced 1-2 months before the subframe bro History: A faint clank from the rear suspension first appeared roughly three years into ownership. Dealer service dismissed it as “normal noise,” and warranty would not cover “loud clanks,” so the issue went unaddressed. The noise has grown steadily into the current condition, suggesting long-term subframe corrosion that was never inspected or remediated. No collision, flood, or off-road use; the car has typical Northeast winter-salt exposure. The failure pattern matches subframe-corrosion cases already acknowledged by the manufacturer on this model, although this serial number is not yet included in the official campaign.

Power steering malfunction Car unable to drive I believe there is supposed to be a recall for this issue but not popping up when I put in VIN number Warning lamps come up. Sometimes every light on dashboard. Took it to Mercedes but it was when code was not popping up and they said I needed a new battery. Did that but still an issue. Has also happened when driving. Sometimes collision assist plus light comes on and power steering acts up. Light I am pointing at in picture is another light that consistently pops up I have been able to intermittently fix problem by resetting computer by unplugging battery for 15min or longer. As well as confirming full service on vehicle. Now it isn’t working though.

No warning lights were illuminated. The vehicle was taken to an independent mechanic, who diagnosed a failure with the steering rack locknuts, observing that the steering rack had become loosened. The vehicle was not repaired. The vehicle was then towed to the dealer, who confirmed the diagnostic result. The vehicle was not repaired. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 18V850000 (Steering), but the VIN was not included. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA hotline for assistance. The failure mileage was 70,000.

I took the car for annual maintenance to Mercedes-Benz dealership. After routine check up they came back to report rusty rear subframe and told me that needs to be replaced. However this part is really expensive and models from 2008 to 2015 C300 had the same issue(premature rust) and they all received extended warranty from Mercedes-Benz for free replacement. I wanted to report this safety issue for C300 model including mine that is not covered under extended warranty.

Rear subframe broke while driving- made stearing/controlling/breaking car very difficult & dangerous.... After reviewing on internet- MB is aware of this problem

Sunshade on panoramic sunroof broke off and tore sunshade. Took it to MB service center and was told it is known issue for that model and many more with some part snapping off causing the damage and cost to repair is between 2500-3000. Have been reading online and lot of people seem to have same issue with the panoramic sunroof and shade not syncing together. Seems to be concern manufacturer should be looking at if there’s numerous vehicle with same issues. Part snapped off when trying to open up sunroof on hot summer day

Have noticed a lot of air noise coming from the panoramic sunroof of my vehicle when driving, and now have issues of it opening or closing properly. I researched and found a recall regarding the issues my vehicle is having, and brought it into a dealership for diagnosis. Was told my vehicle VIN was not included in the recall. This is a dangerous issue that needs to be remedied. If the sunroof malfunctions I’m afraid it will come loose from the vehicle as it is doing the same things that the recalled VIN vehicles had issue with. Mercedes needs to update and add additional VINs to this recall. I did not repair, as I was told the entire thing will need to be replaced.

The contact owns a 2015 Mercedes-Benz C300. The contact stated that while driving at approximately 70 MPH, there was a loud clicking sound coming from the panoramic sunroof. The contact stated that the sunroof then became inoperable. The contact became aware of NHTSA Campaign Numbers: 23V854000 (Structure) and 21V197000 (Structure). The dealer was contacted and confirmed that the VIN was not included in the recalls. The vehicle was not diagnosed or repaired. The manufacturer was informed of the failure and confirmed the VIN was not under recall. The manufacturer referred the contact to the NHTSA Hotline to report the failure. The failure mileage was 115,000.

I took my vehicle to an independent repair shop for routine maintenance and while there I was advised that the vehicle is suffering from the subframe corrosion issue. I called the manufacturer service center and they took my VIN and said I was not covered under the bulletin. The independent contractor gave me an estimate to get it repaired, however Mercedes doesn’t even have the parts needed in stock as they are backed ordered nation wide.

I had the sunroof opened and it almost blew off, if I didn’t pull over it would have. I took it to the shop and was told it is a manufacturers issue.

The engine lamp turned yellow. The car got inspected by a mechanic and showed code. P052E, which indicates the defect in the crankcase ventilation valve. I see that many cars of the same model in which were produced about the same year had the same defect. I called the manufacture customer service and they claim that my van was not included in the recall. My vehicle likely had the same problem as other people did in the past, but for some reason my vin was not included.

P052e positive crankcase ventilation regularly valve. 2015 Mercedes Benz c300 turbo 4matic

I believe my car was missed on the panoramic roof issue. I have been hearing a lot of wind and road noise coming into my car from the roof and now my roof is having issues completely closing. A few guys with c300 I know were recalled for the same issue and they had theirs repaired from the dealer under recall and after a few trips to different dealers they told me to try and add it here through the website.

Known/ common issue with the positive crankcase ventilation regularly valve on my 2015 c300.

The rear subframe rusted and needed complete replacement. The service department would not pass the car for inspection without replacement. My brother, who also has a Mercedes C300 model but from the prior year, reported that he had the exact same issue. However, Mercedes issued an extended warranty on his model. In researching this issue, I have discovered that this rusted subframe issue is prevalent in C300 models in all years, not just the model years before mine. I compared the service notes from my invoice with my brother's invoice. It is the exact same issue. I contacted both the Mercedes dealership and Mercedes corporate about this issue, seeking resolution. I provided them with all the documentation. Their answer is simply that my VIN does not qualify under their extended warranty and refused to look into it further, despite my pointing out that it is the exact same problem.

The defect is a rusted rear subframe with large holes that will break and cause wheels to become detached and lost control of the vehicle. The issue was identified and repaired by an authorized Mercedes dealership. Additionally, an authorized Mercedes mechanic provided video of my vehicle showing a rusted rear subframe with huge holes on both sides of the vehicle. He also stated the vehicle is unsafe to drive. Mercedes has issued an extended warranty on this same exact issue but only to certain VINs.

My car (vin [XXX] ) a 2015 Mercedes C300 is experiencing the same premature rusting on the subframe. I was told that while a lot of Mercedes are covered, mine is not for some reason but I'm at the same risk for the subframe getting holes in it and wheels breaking off. I only have 78,000 miles on my car, only have it serviced at the dealer and it has been garaged parked. This type of damage is not typical for a car that has been this well cared for and for the amount it has been driven. I called Mercedes to honor the $5600 or to extend the warranty should it have to be replaced and they said to file a claim here.

The rear subframe is rusted through. It is a known manufacturing defect where water sits and rusts through the subframe. This was a recall on various Mercedes up through 2014. Multiple 2015 models have the same issue, including my Mercedes 2015 C300 4MATIC. I have a 2009 SLK with the same issue, which Mercedes previously fixed and acknowledged the manufacturing defect. The part number under the recall through 2014 is "212 250 3805" My 2015 car has part number "212 350 3605" that is not covered but still has rust issues. See attached picture The subframe can result in the back wheels falling off. My subframe is severely rusted through and a risk as a driver. A certified Mercedes dealer has inspected this issue and confirmed the safety but Mercedes will not cover the repairs for the known defect. There are no warning lights or indicators to this issue.

SUNROOF SLIDE AND SHOE REPAIR. SLIDES HAVE MELTED DUE TO HIGH TEMPERTURES OWNER OPERATIOR DID NOT CAUSE ISSUE. Opened sunroof and sunroof would not closed. Discovered melted slides inside to sunroof tracks. It was a Rainy day and could not get sunroof to closed. Would have interfered with the visibility to drive due to water getting inside vehicle. Cost to repair is extremely high for this repair and when contacting repair shops they are seeing a large number of Mercedes with the same problem.

Known issue with panoramic sunroof on 2015 Mercedes C300 sunroof. Having to be replaced on “many” vehicles costing over $2500.00 for repair. Sunroof gets stuck and will not close.

My boyfriend and I were driving my 2015 MB C400 down the road in November 2020 and it was a beautiful day out so we decided we would open the sunroof to get some fresh air. I was driving so my boyfriend pressed the button for the sunroof to open. As the sunroof was opening, there was a cracking and popping sound coming from above us. We immediately pulled over at a gas station to see what was happening. Upon getting out of the car and looking closer at the sunroof, we noticed many cheap plastic components that were just broken and crumbled laying inside the sunroof tract. We removed the broken pieces and then tried to close the sunroof several times. T Each time, the sunroof went into the closed position BUT immediately went straight back to the popped up position and would not completely close again. I took my car to the MB dealership in Athens, Ga where they told me it would be almost $2500 to repair which I did not feel as if I should be held responsible for as I had just purchased the car in January 2020 only 11 months earlier. I was in fear that the sunroof would detach from the car and cause serious injury to any motorist behind me. I also have a [XXX] son who is now scared to ride in my car!! After doing much research on this issue, I have found that this is truly a common problem with this MB model. I have reached out to the corporate office a few times and they only tell me that there is no active recalls with my cars VIN. It is completely unacceptable that MB is fully aware of this issue yet they continue to disregard the potential harm to other motorists. Please help!!!

Crankcase ventilation valve. PCV valve has failed causing check engine light. Very common issue on this model according to my research.

PCV VALVE FAILURE PO52E ERROR

Very strong gas smell inside the car when started and heat or air is turned on. I have done research and it is a common issue with this car. This is a very serious issue that can cause an engine fire with the gas leaking in the engine compartment.

My car is a 2015 Mercedes Benz, I bought it at the agency in 2022. When I tested the vehicle at the agency, I noticed the steering was a little hard. I asked the sales person and he told me it was normal. Then, after 1 year and 5 months, it was on its way. I went to work and the steering wheel jammed and it wouldn't cross and the car turned off then it didn't want to start and it said the following on the dashboard power stering see operator manual

I got an oil change since it was due then “P052E” It’s a very common issues with the engine first time it’s happened at 66K miles.

I got my oil changed last week and not my car has the check engine light on and is throwing the code p025e. From what I’ve read this is common problem in these cars. It’s an environmental hazard, because when this happens the car is not dispelling the fumes as it should and cannot be ventilated correctly.

Code P052E

Pcv valve malfunction causing the 0sensor to short. It’s also spitting oil into my CAT.. Mercedes has the part on back order and no one can seem to get it but everyone is having the same issue.

Crank case vent valve assembly

My wife and I were driving our 2015 C-Class Mercedes on a highway, traveling at roughly 55MPH on 2/25/24, at approximately 2pm, conditions were sunny but windy, when suddenly we heard a loud noise above our heads. The noise sounded like it came from around our sunroof, and it sounded as if maybe the car had been hit by a piece of debris, although neither of us saw anything. We looked in our mirrors but didn't see anything, and I also tried opening and closing the sunroof and it worked fine. I also looked in my rear view mirror and didn't see any cars behind me swerve, or in any way adjust their driving. Because there was no safe shoulder on that part of the road, we continued a mile or so further up the road and then pulled over to see if we could visibly see anything wrong with the car. To our disbelief, a section of the body of the car that is just above the front windshield and just before the sunroof, a piece I believe called the "front stationary sunroof panel" , was completely missing! We were unsuccessful at finding the piece. After some research in recent days, I believe this issue is related to MB recall campaign #2021070010, 22V-954 / 2023010004/5/6. If this is however related to the recall, the Mercedes dealership we took our car to on 3/1/24 told us it would cost us over $2,000.00 to repair. As I thought about a piece of the car simply flying off while driving, I realized how much of a safety hazard this could pose to others, hence this written report.

Crankcase breather faulty

The panoramic sunroof is faulty. Doing a simple search online showed that this is a common problem amongst my vehicle model where parts are loose or misinstalled and it is a safety concern in a potential accident or rollover. My dealer is now looking into it and it is also an excessive out-of-pocket cost to make the vehicle safer. Something I do not expect from a high-end vehicle manufacturer. I identified this due to the rattling sound in the ceiling/sunroof.

Some people have had to replace this part multiple times for their Mercedes which is a part that shouldn't fail. Nothing has been done such as a recall on this vehicle.

I have a 2015 Mercedes-Benz C300 4Matic got a letter from the company car had few recalls to address. Dropped the at Mercedes-Benz Hampton VA dealership on 12/06/2023 at 8:30 AM EST. After few hours got a call from the dealership that rear subframe of the has bad corrosion and because of the rust it got holes in it which is a bad safety risk. Risk is so great that it cant pass Virginia state inspection. I did a good online research and found it is a common issue in Mercedes-Benz vehicles and the company issued safety recall on some years and models but not on all the affected vehicles. Like my car has the exact same safety issue rear subframe got rust from inside so it was hard to notice till it became unsafe to drive the car. The dealer is asking almost $5000.00 to replace it. The Mercedes-Benz customer support center is unable to explain why some cars are covered with extended warranty offered by the factory and some doesn't for exact same issue. There are bunch of more people with same complaint but they don't know where to go.

This concern is putting me, my wife and kids in high risk and unsafe driving condition. I did some research and found out that the manufacture of this car put these electronic sensors inside the rear bumper behind both rear wheels and are exposed so whenever driving, rain, dirt, salt and all road debris splash all over these electronic sensor causing them to corrode and destroyed as a result of water and salt getting inside these fragile electronic sensors and then, the whole blind spot system inoperative and of course high risk to get involved into an accident.

While driving on highway a load noise was heard pulled off the road to see what it was and the part of the sunroof that meets the windshield had raised up so we tried to push it down and continue towards home the car had to be driven at around 40 miles per hour to keep it from elevating and in fear that it might come off and hit someone's car or cause an accident

I have 65000 miles on my car. It is 2015 Mercedes C300. My Engine light came on. Found out that Crankcase Vent Valve needed to be replaced. Cost me 1200 dollars. It appears that lot of Mercedes C series cars have the same problem. I feel that Mercedes should pay for it.

My car is the 2015 Mercedes- benz (MB) c 300 4MATIC. The Check engine light is on and off for some months as initially MB dealer said that it's likely due to gas cap defects so we replaced the gas cap. After that, the engine light is still on and off. MB dealer now said $1,760 to replace crankcase vent value and $2870.55 to repair the front differential leaking/reseal. It will cost me a total of $ 4630.55 +tax to repair. The car has only 70,000 miles and kept good maintenance frequently. Right now my car is not safe to drive it so why this car is broke down so quickly. That is not acceptable to us.

Engine check light code: P052E Crankcase Ventilator / oil separator. Huge problem could cause the engine to stall while driving. Could lead to an accident if you are trying to merge on the highway and the engine stalls out.

Mercedes 2015 C300 crank case ventilation hose has a defect and it is well-known to the manufacturer. This causes recurring engine and exhaust problems for a large number of car owners, and it should be part of a recall.

During a drive, I had the sunroof opened and then it suddenly started raining. When I tried to close the sunroof using the button, it wouldn't budge. I had to continue driving on the highway with rain pouring inside the vehicle. When I finally found a place to stop and check the sunroof, I saw that the roof on one side was popped off. After a few minutes of trying to close it, it finally popped back into place on its own. However, now there is a rattling sound coming from the sunroof when driving, and the car is no longer quiet. I can hear outside noise as if a window is cracked opened. Every time the sunroof opens and close there’s a slight popping sound on that side and looks like it is still out of place.

My 2015 Mercedes c300 only has 39k miles and suddenly the engine light on, when I check, the dealer it shows that I need Positive Crankcase ventilation valve replace. it cost $2300. This is basically a brand new car and needing this repair every 30k is a joke please issue a recall and have Mercedes held responsible

The service center advices that I may continue to drive the vehicle. However, I am concerned should the oil fully empty without warning the vehicle may fail while in use on a dangerous roadway due to cause and effect of additional unknown maintenance related operational co-dependent mechanical components.

Crank case breather assembly needed replacement at 31,200 miles. Service mech. Advised the leaking area (oil) could not be repaired since Mercedes does not sell replacement parts and entire assembly needs to be replaced. March advised Mercedes is aware of issue and has redesigned the entire assembly. Cost for part was $400+ and labor to install was $1000.

Upon inspecting the vehicle, the contact noticed that the roof panel had loosened. The contact stated continued driving and the roof panel fractured and partially separated from the vehicle.

My vehicle is a 2015 C300 AWD. One day I was driving on the highway and noticed white smoke coming out of the exhaust. The check engine light came on shortly after as I pulled over. Being that I was less than a mile from my house, I decided to go park the vehicle. I noticed that it was losing power and had problems going above 45mph. Since my vehicle had 99k miles. I took it to my indy mechanic that has worked on the vehicle since it has been out of warranty. When he diagnosed the vehicle, 48 codes came up. He suggested we change the spark plugs and coils, which we did. Didn't fix the problem. Then he suggested we change fuel injector 1, which we did. That didn't solve the problem. I decided to take it to the local Mercedes dealership where they did another diagnostic test. And like many others here, cracked piston/cylinder 1 dead. I'm looking at $18,000 in repairs. I told them no thank you. The car is now sitting in my garage. I really hope Mercedes makes this right with its customers. There is no reason why this many people should be having this exact same problem.

2015 C300 Crankcase Ventilation Valve Replacement P052E71 NEED TO BE REPLACED, ENGINE LIGHT COMES ON. ONLY HAVE 37,000 MILES MANY REPORTS OF THIS ISSUE

PVC valve shouldn’t fail and each time it does it is around 2k dollars.

my car is a 2015 C300 class Mercedes-Benz, as I was driving, the car suddenly and without warning began to vibrate and shake violently and immediately lost power. Fortunately I was off the freeway, a serious accident could have resulted. I took it to the the local MB dealership and they told me that the car failed a compression test in the #1 cylinder and that the engine would have to be replaced at almost $17000. Of course, this was beyond warranty, Mercedes know it’s a defective product, they refused to act responsibly. This cracked piston which is a design flaw by Mercedes needs to be recalled, a lot of people are reporting the same issue.

The problem is actually a manufacturing defect in the wrist pins. The defective parts are in engines made before April 20, 2015 which is mine. If left unrepaired, it causes premature wear in the cylinder walls. The issue on my car been confirmed by mb dealer.

obd2 scanner reported Error Code P052E which seems a very common issues on Mercedes C class 2015 or newer and there is no recall issued by Mercedes Benz yet which points out to possible problems with "PCV Regulator Valve components. There are 100s of post in the forum related to same issue

My son's car was blowing white smoke out of the exhaust and had a sweet burning smell and the check engine light came on. The crankcase vent valve is needing to be replaced on this 2015 C300 Mercedes Benz and many owners of this same type of car (different year) are posting about it. Owners of these types of cars are saying that replacement is happening more than once! That it's a common defect of these cars. My son has less than 100,000 miles (61,000 if that) and this shouldn't be happening. And, it's time someone does something to protect the consumer. Mercedes-Benz dealers are taking advantage of consumers and charging ridiculous prices to replace this part, but the part shouldn't be breaking. It's a safety factor in that it can affect driving, there's risk of blowing valves/valve cap and engines, including loss of the vehicle and nowadays no one can afford to buy a new car or even a used one! Consumers buy what they think is a reliable vehicle but Mercedes isn't taking care of their customers. Mercedes-Benz should be forced to do a recall and replace these faulty parts.

Driving the 2015 c300 with approx. 69k in miles down the highway and heard a pop and the check engine light came on. The next day there was a rough idle and clanging at low speeds. took to dealership and they quoted me $15k in repairs for a new engine. MB tech said the cylinder #1 is out of spec., and there is scoring on cylinder wall caused by the piston being off center and riding the cylinder wall. After doing research this is a common problem with the m274 engine. How has this not been recalled and taken care of by Mercedes?? At this point i am 'forced' to either come up with $15k for the repairs, or go to MB dealership and try to get into a new car...which i am over $12k upside down on i might add

Check engine light came on and strong fuel smell. Crankcase ventilation malfunction code was verified by dealer.

The car smell like gasoline inside, the gas hose connecting the high pressure gas line to the gas tank is licking due a bad connectors

When driving I accelerated and then the engine light turned on. after that the car was jolty and turned off completely when stopped. had to force a restart at the light. code that came back was p052E. This is a major and common issue with these cars. part is 400+ dollars. labor is much more since this is a 6 hour job. the work to replace this part is incredibly intensive that makes it impossible for regular car owners to change. Mercedes refuses to recognizes this as a common issue. but the truth is they designed a faulty system that they claim to have updated a handful of times now.

My check engine light was on when I was driving on the highway. I was terrified that something was very wrong. Right after, I took the car to the dealer and was told that the valve for the crankcase ventilation. The actuator was blocked. I was also told that this is not caused by something I did. It's the design of the car that caused the problem.

I was quoted 1600+ for a repair for something has been known about for over 7 years to be an issue with the car class.

Oil separator failure. This a common design fault as documented by multiple complaints on the internet. This is another Mercedes Benz emission design flaw causing emission failures. This is very cheap part but extremely expensive to replace. Mercedes collects over $1200 per labor repair for each. THIS IS AN EMISSIONS POLLUTION AND SAFETY ISSUE THAT CAN BE SOLVED. PLEASE FORCE A RECALL. Engine severely smokes/stalls leaving people stranded on highways. When stuck, coolant is sucked into the engine mixing with the oil. No warning. The car

I have 2015 C300 Model, total milage on the car is 30K. Dashboard is showing the check engine light and when I take to Dealership for diagnostic, the code is P052E which is a problem with Crankcase vent. Dealership tech had mentioned that this seems to be known issue effecting years 2015-2018. When I did search, he is right; many MB owners are facing same issue which is a malfunction during assembly/manufacturing. MB should be responsible for part replacement and labor. Please investigate and ask MB to run recall campaign. Thank You.

Front Roof Panel Discoloring and Detachement

Vehicle experienced loss of power and rough running when check engine light came on. Mercedes dealer reported one of the pistons cracked resulting in catastrophic engine failure with just shy of 61,880 miles on it.

These cars have a known wrist pin failure, mercedes refuses to cover the cost of repairs as its not a recall. My vehicle is the specific model and year this is known for, and my car is making these piston slapping sounds, worse everyday. Worse on deceleration, goes away when warmed up, just like the reports. I am afraid I'll lose power while driving and hurt myself or others.

I have an emissions related Check Engine Light (P052E71) relating to the Evaporative/Crankcase ventilation system. I think this should be a Recalled/Warrantee item on the 10 year/100,000 miles federally mandated guarantee. Please advise...

Failed component: power steering. Mercedes Benz of Princeton did the replacement, but we're not sure if they kept the part. Safety issue: On June 14, 2022, the vehicle’s power steering failed in the middle of a drive (see attachment for the error message). This was a major risk since the car was stuck in the middle of the road, with the steering wheel requiring tremendous force to turn. Luckily, we were a few 100 feet away from home, so we just left it. Next morning the car turns on fine and there are no issues with the steering. One week later, on June 19, 2022, the issue resurfaced. This time we were driving 35mph in a public street with traffic behind us. We were barely able to pull the car over to the side of the road. We took the car to Mercedes Benz of Princeton where they diagnosed the issue and quoted $4551 to replace the entire steering rack. We also contacted MB USA to understand why our vehicle wasn't recalled as part of NHTSA Recall ID #15V-845. After dragging their feet for a full month (where no updates were provided), they denied the claim. On July 22, 2022, we ended up paying the full cost of repair and lost the use of the vehicle for a full month.

While driving on the highway, I heard a noise.  While still driving , I quickly looked around which included looking in my rear view mirror.  I saw something in the air and saw it hit the road.  It didn't occur to me that what I saw flying was from my car.  I thought the noise was from some part of the object (maybe a screw) hitting my car.// When I got to where I was going, I walked from my driver's side around the back of the car looking to see if there were any noticeable issues.  When I didn't see any issues, I decided to walk to the front of the car where I noticed the panel missing between the top of the front windshield and the sunroof. // I found the following article: https://www.carcomplaints.com/news/2021/mercedes-benz-sunroof-problems-cause-recall.shtml The scenario described in the article happened to me on Saturday 27Aug2022: "And a 2015 Mercedes C300 driver heard loud wind noise coming from the top of the vehicle near the windshield while driving above 40 mph. ... while driving on the freeway the driver heard a loud ripping noise and realized the panel was missing. The sunroof panel that flew away wasn't found."

The manufacturer had been informed of the failure and the contact was informed that the VIN was not included. The failure mileage was approximately 50,000.

Strong odor of fuel in the cabin when entering the cabin and stronger when vehicle is first started

I took my vehicle to the dealership to have recall worked on (top sunroof panel) apparently they refused to work on it because my sunroof is not working. I received a letter after i financed the vehicle stating that there was a recall so to take it in to the dealership and if sunroof needed to be fixed it would. Long story short, back in July the panel detached from my vehicle while i was on the freeway. Thankfully I didn’t cause an accident but I would like some help so the dealership can fix the recall.

The contact owns a 2015 Mercedes-Benz C250. The contact stated that the vehicle would suddenly stall while driving at various speeds. The contact would have to place the vehicle in park, turn the vehicle off then on again to regain proper function. The vehicle's collision prevention assist plus inoperative warning was illuminated.

Crankcase ventilation (PCV system), on C300 and GLC 300 is a know issue with this model care fro 2015 to 2021, yet Mercedes Benz manufacture the cars the same way with addressing in order to over charge customers and claim it’s a wear and tear part

The contact owns a 2015 Mercedes-Benz C300. The contact stated while driving 60 MPH, the power steering malfunction message appeared on the instrument panel. As the contact attempted to exit the highway, excessive force was needed to steer the vehicle.

The failure mileage was approximately 130,000.

Reported to local dealer and corporate office about the issues with shift module not shifting at random, meaning that the vehicle won't shift from park to drive or reverse, and so forth. The local dealer tried to reprogram the software, but the problem still persists. When plugging in my OBD II & DTC readers, code U0103 appairs which translates to "Lost communication with gear shift control module". My concern with this is that I've had this issue while in traffic, which would make my vehicle a hazard. When it comes to the collision prevention system, the system randomly turns on and off, meaning that when it's needed it might turn on, but when it's not needed it randomly turns on. Once again, addressed this with a local dealer and Mercedes Benz corporate with no avail. My concerns here is that the vehicle could prematurely brake causing an accident or not brake at all causing an accident.

Check engine lite with code P052E that is "Positive Crank Case Ventilation Regulation Valve Performance" at around 65K miles. This might pose danger with engine failure. the problem has been confirmed by an independent service center. Dealer said that this problem is common to the year and model of my car and that the manufacturer has replaced this piece in newer models. Since the manufacturer already know this issue and replaced the piece with a better one for newer model. I believe this part should be recalled and replaced by the manufacturer. it is crazy amount of money for the consumer to fix this.

The contact owns a 2015 Mercedes-Benz C300. The contact stated that while driving at various speeds, the vehicle would intermittently fail to accelerate upon the depression of the accelerator pedal. The contact took the vehicle to an independent mechanic where she was informed that the turbo booster was defective. The contact then took the vehicle to another independent mechanic where the oil circulation and turbo booster were replaced. After the repair, the air bag warning light was illuminated. The vehicle was taken back to the independent mechanic where the vehicle was diagnosed with a defective clockspring. The dealer was notified of the failure and informed her that there were no recalls on the vehicle. The manufacturer was notified of the failure and referred her to the NHTSA. The vehicle had yet to be repaired. The failure mileage was unknown. The VIN was not available.

This is in regard to my 2015 Mercedes Benz C300 4 matic. I was driving at the normal speed of approximately 65mph on the highway. When out of nowhere, I heard a very loud wind noise. I was terrified since I was alone and was not sure why or what happened. I pulled over and noticed the front panel of my Sunroof glass was missing. I was very disappointed as I have always believed that MB has had a strong reputation for their cars. I circled back around and was able to find the part on the side of the highway, but it was broken. I have had heavy-duty tape covering the space so water cannot get in. I contacted my local MB repair shop and told me the part would be $1100 and labor would be additional.

Cracked cylinder #1. Causes rough idle, loss of power and lots of white smoke out the tail pipe. This is dangerous for anyone behind the car trying to see through the smoke then loosing power and other vehicles almost hitting me. Mercedes know they are defective but because of the large cost associated with repairing them they will not fix.

2015 C 300 Mercedes Benz Crankcase ventilation/ oil separator is bad. Vehicle has only 50,000 miles. Please help, Mercedes should have this on recall, a lot of people has this same issue. Thanks

The dealership garage isla verde in carolina, refuse to service my car. They are the only Mercedes-Benz dealer in Puerto Rico and there is no other dealer that can service the recalls of my car. Currently they don’t want to fix the recall NTHSA# #21V197 Bonding of Panoramic Sunroof Panel - Wave 2 MY. Their service is poor and negligent. They make an appoinment to then cancel it and deny receiving me or my car on the only authorized dealer to fix the recall and denying any services to my car. They refuses my entrance.

Cylinder #1 losing compression. Onset acute after exiting freeway. Car lost power. Engine warning light turned on. Independent repair shop advised compression problem in Cylinder #1. Dealer then inspected and advised there was compression loss in Cylinder #1. Dealer recommended engine replacement (not repair). The car only has around 46,000 miles and is a 2015 model.

The crankcase ventilation valve has gone out on my car. This is a continual problem with these vehicles at low mileage. Mercedes Benz should recall the part for repair as they stated it could damage the engine.

ONLY HAVE 35,000 MILES AND RECEIVED POSITIVE CRANK CASE VALVE

Got error code P052E when performing state inspection for my car. This looks like "Positive Crankcase Ventilation Regulator Valve" issue and have seen lot of people who owns Mercedes Benz reported this issue.

There wasn’t any warning lamps prior to my rear right tire exploding on highway.

The tire exploded on highway,left sever damage on my car. The dealership ruined even more by trying to fix it. I think this tires are not safe to drive on the road. since I didn’t use the car less then 4000 miles a year.

PCV (Positive Crank Ventilation) error fault. Error message keeps coming and is affecting a large number of vehicles.

MY VEHICLE'S Positive Crankcase ventilation valve NEEDS REPLACING. AFTER RESEARCHING THIS ISSUE FOR A WEEK IM LEARNING THAT THIS IS A VERY COMMON ISSUE WITH MY VEHICLE'S MAKE MODEL AND YEAR AND IS LIKELY TO OCCUR MORE THAN ONE TIME IN THE VEHILES LIFETIME. THE PROBLEM HAS BEEN CONFIRMED BY AN INDEPENDENT SERVICE CENTER I WAS MADE AWARE OF THE ISSUE BY MY VEHICLE'S CHECK ENGIN LIGHT

I keep getting a litany of warnings on the dash.

Looks like I am not the first one to complain about the strong smell of fuel on the driver side under the hood as well as inside of the vehicle. Upon further inspection it was determined that the fuel line at the pump is leaking fuel. My car has only 48k miles on it...How can such dangerous failure be ignored by MB for more than three-four years or longer?? Please note that this particular issie is leading the complaints chart. Based on the amount of identical complaints, it appears that this "manufacturer" is waiting for an injury or fatality before they do something about it. This fuel hose situation MUST be addressed IMIDIATELY. Please start the recall before it is too late!!!

Car was parked in Garage with garage door open. Wife and I wanted to go biking and the bikes needed air in the tires. Pre-positioned one bike directly behind parked car and one parallel with the pneumatic air pump prepositioned to inflate the tires. Went to driver's side door and started car with foot on the brake and pushed the button. I then plugged in the adapter for the air pump into the cigarette lighter. The whole time the driver's side door was open and the car was not moving. I exited the car and walked backwards and knelt down abeam the left rear automobile tire to inflate the bike tire. I started the pump at the unit and started to connect the hose to the bike tire, I was then hit from behind by the car door which bent backwards as it passed over me in reverse at low speed. The bike may have saved me by creating a wedge to bend the door back and away from me. The car started down my driveway and dragged the bike parked behind it underneath wedged and sparking across the ground. I got some scrapes but jumped after the car and tried to stop it by trying to slow it with my weight and strength and it was not stopping or slowing. I was worried I may get run over a second time and let it continue to roll at low idle speed across the street and into the neighbor's car that was parked. I am positive the car was not moving after I started it and I didn't have my foot on the brake to engage the reverse function one I exited the vehicle. I believe that the car engaged in reverse once I started the air pump. Maybe it was a voltage or electrical spike. I have used this pump setup many times before to inflate the car's tires and my bike tires but never saw it do this before.

This vehicle has a known issue of the timing chain needing replacement around 80,000 miles. When I hit approx. 78,000 miles i started hearing strange sounds and issues with my vehicle starting so I took my vehicle to a local mechanic and he said that the timing chain needs to be replaced. he also stated that there should be a recall on this issue as there has been a recall on the same vehicle for the same issue just a different year which has the same exact engine therefore this year of vehicle should also have the recall applied for the timing chain to be repaired. This issue is causing engine problems and will eventually lead to the engine completely blowing at any time now.

I got a P052E code on my car which means a faulty crankcase or PCV valve. After doing some reading it seems to be a super common problem.

While driving, heard loud flapping noise and when stopped discovered the tread on driver side rear tire had separated from the tire and was hitting wheel well, and passenger door. Road was clear and smooth prior to the incident Happened Saturday, March 5, 2022 at about 1:30 pm. Consumer stated Pirelli Risk Management wanted to make arrangements to have the tire shipped to them for inspection.

Long story short, I own a 2015 C300 Mercedes with 59,500 miles I was driving on the street when my engine started shaking so rough and my car lost power. I panicked and pulled over and drove 10mph all the way home. My vehicle would shake rough, couldn’t exceed 10mph and would make loud noises. I take it to the Keyes Mercedes dealership and they tell me it’s a cracked piston. I couldn’t believe it because I only have 59k miles. I have my vehicle records so I have been up to date on my maintenance. They dissembled my engine and couldn’t find the cause to the failure but found the cracked piston in cylinder #1 and damage to the cylinder walls. They recommended to replace complete engine and it will cost me about more than $18,000!! The piston falls under Mercedes 7 year/70k miles emissions warranty and yet they deny coverage. After doing lots of research I come to find out that I’m not the only victim that has suffered the exact damage. People that also own a Mercedes c300 and other models are now without a vehicle and looking at a repair of $18k+ and making a car payment for nothing. This has caused us stress, inconvenience, and damage to our mental health. Keyes Mercedes located in Van Nuys is also aware of the common cracked piston issues on their vehicles. In 2 days I mark 4 months without my car. Please help!!

PVC Pipe to turbo. I am very concerned because this is a reoccurring issue with many owners of C300s. Also, I think it is related to recall number 20V364000 Engine and engine cooling: Engine: Gasoline: Turbo/supercharger. The issue was confirmed by a dealer Check engine light illuminated.

When I got my Mercedes 2.5 years ago I would always notice a very strong gas smell that would come very randomly. I would have to open my windows for the smell of fuel to go away. I presented this to the Greenway Mercedes Dealership 2X VERBALLY and they told me that it is just a "Mercedes thing" and everything is ok because it is not "VISIBILLY" leaking fuel. Which it was not. However, the smell of the fuel is EXTREME, It would happen to me through out the year (in the summer and winter, regardless of temperature) randomlly. I would have to leave the garage ASAP when I turn on my car just in case the smell of fuel was extreme because my parents would tell me that it would even COME INTO THE HOUSE. I thought I was crazy to think this was normal and just a "Mercedes thing". But then I got a letter on August 2021 and did some research and saw I was not the only one and there is a class action lawsuit -Mercedes sent a letter on August 21 announcing they will extended the limited warranty of the "Fuel hose connected to high pressure fuel pump" from the original warranty of 4 years/50,000 miles to 10 years/120,000 miles. HOWEVER, This does NOT HELP, they are still saying it is a wear and tear and REFUSE to replace the defected MANUFACTORER part and INSIST it is not "seeping fuel" from the connection at the fuel pump, so it is NOT under warranty. I am confused as to why this is not a recall? Extending the warranty did nothing to help Mercedes Owners at all. They continued to claim it is "wear and tear so that is why the fuel is sweeping at a different location" AS WELL, two dealerships told me it would take them 24-48 hours for them to JUST INSPECT my car to see if it is covered. This extension did resolve anything, but made sure the dealerships deny even more. Now, I have to continue to leave my garage within 30 sec. so I don't suffocate the cats that sleep in the garage or have my family smell the fuel as I leave. And to open my windows so I can breath fresh air.

Car has 51,000 miles , no check engine light or any other warning light .driving in on the freeway at 70 mph when I hear a pop sound and my car loses power , I pushed on the gas and it started to shake violently and I panicked as the construction on the freeway was not allowing drivers a shoulder to pull over on . I was lucky enough to be driving at 2am and with the construction going on , drivers were already slowing down . My car also started blowing a thick white smoke through the back exhaust that could have made it harder to see that late night as it was already foggy here in California . At first I didn’t realize I was smoking through the back until my car began smelling like burnt oil . I wasn’t able to get off the freeway until the next exit all while thinking that my car was going to explode from the smell of the burning oil . When I pulled over and got out of the car I made sure I didn’t see any fire and then I waited to let it cool down , opened the hood and saw oil everywhere . I had it towed to Mercedes and I got the problem and the estimated cost to repair it . The problem turned out being a cracked piston in cylinder one , when it cracked it allowed oil to mix with the gasoline and that’s what was causing all the white smoke out the rear , the burnt smell was from the oil that was leaked all over my engine getting too hot from the engine. I found out a few days ago that Mercedes’ has a technical billeting regarding a faulty wrist pin that was causing the pistons to eventually crack . In the bulletin the faulty pin problem is fixed by replacing all the pistons and adding a upgraded pin and many other parts . So there are many other drivers that are experiencing this and driving with faulty wrist pins . Prior to all this happening the car always made a tap tap tap sound from engine and Mercedes’ said it was normal for 4cylinder turbos to make this sound, sounded like a diesel . But it turned out being from the loose wrist pin . Mercedes lied to us . THE CONSUMER REQUESTED THAT MERCEDES BENZ VEHICLES, WITH THE M274 ENGINE, BE INVESTIGATED. THE CONSUMER STATED THE VEHICLE SUDDENLY LOST POWER. THE CONSUMER STATED THE CAUSE MAY BE DUE TO A WRIST PIN THAT IS THE WRONG SIZE.

The contact owned a 2015 Mercedes-Benz C300. The contact stated that while idle, the engine would vibrate with an abnormal sputtering sound coming from the engine. As the failure persisted, the check engine warning light illuminated. The contact had initially taken the vehicle to a dealer and the spark plugs were replaced; however, the failure persisted. The vehicle was returned to the dealer and a diagnostic test was performed, and it was discovered that an engine cylinder had blown. The vehicle was diagnosed with engine failure and the contact was provided an estimate for the repair. The contact then spoke to an independent mechanic who informed her that the failure was a common failure for her model vehicle. The manufacturer was also notified of the failure and a case was filed. An email was sent to the manufacturer and the contact was informed that no further assistance could be offered. The vehicle was not repaired. The failure mileage was approximately 50,900.

The wrist pin is defective in early engines during manufacturing. It is not safe to operate the vehicle because at any time without any warning this can cause fatal damage to the engine - piston crack resulting in total loss of control even at high speeds on the highway. Numerous complaints were filed on NHTSA regarding cracked pistons most likely related to this wrist pin manufacture defect. The problem is acknowledged by M-BENZ (NHTSA ID Number: 10058545), and starting around April 20 2015 M-BENZ started to install modified wrist pins to prevent future failures, but they did not address existing faulty wrist pins. The vehicle was always serviced at the official MBENZ Dealer service and was under comprehensive inspection multiple times but the issue was never acknowledged by the service technicians during the warranty period even though the issue existed since manufacturing and instruction of how to diagnose was distributed between service technicians via Manufacturer Communication Number: LI03-10P060916 in 2015. When the M-BENZ Delear service technician finally confirmed the issue, the vehicle was already out of warranty and there is a hefty price to a customer to fix this manufacturer defect that should not have been there in the first place. There are no warning lamps, messages, or other easily detectable symptoms of the problem prior to the failure. The issue can be diagnosed under very special conditions described in Manufacturer Communication Number: LI03-10P060916 For most drivers, it's hard to diagnose that something is wrong and easily mistaken for normal operation noise of the engine

Recall 2021070010----NHTSA #21V197--Panoramic roof not boned correctly to the vehicle during prior replacement -

The car have anew recall Recall #2021070010. The dealership Garage Isla Verde won’t provide me any type of services to my car. Neither repair this safety recall. They cancelled my appointments because I’m not welcome to the dealership.

Without any warring or indication my engine would start making bad noise then light comes on to check engine as the motor fails and car shuts off. This is while driving and has happened two times now. Both times I find it’s due to spark plug failure and pieces of the plug go throughout the engine and severely damage. First time this happened at 82,000 miles and was covered by warranty. Now this has happened again on the new engine with 81000 miles on it. I seen many forums on this issue. This time it’s not under warranty and it’s $18000 to fix. Mercedes Benz w205 engine seems to be notorious for spark plug failure in cylinder 1 as well as piston cracking. The first time this happened was October 12th 2019 and the warranty work was done at fletcher Jones Mercedes Benz of Newport Beach

Power steering malfunctioned while driving. Received error on dash. The steering wheel was very difficult to turn. Issue was resolved after turning the car off for 5mins and restarting. However it is unclear whether the issue would fester again. This is the first time this issue occurred between 2017-2022.

The contact owns a 2015 Mercedes-Benz C300. The contact stated that a strong fuel odor could be smelled from both inside and outside the vehicle. The vehicle had to be serviced for the failure; however, upon inspection, the contact believed that the source of the odor was from the engine fuel lines. The dealer was notified of the failure and informed him that there were no recalls on the vehicle. The manufacturer had yet to be notified of the failure. The vehicle had yet to be repaired. The failure mileage was approximately 102,000.

Constant fuel smell coming from the engine, you can see gas coming out of the high pressure line. When I park in the garage the whole house smells like gas. Even while driving gas smell coming through the vents constantly

The contact owns a 2015 Mercedes-Benz C300. The contact stated that while driving approximately 50-60 MPH, the #1 piston cracked. The contact stated that while his daughter was driving, the vehicle was shaking and smoking. The check engine warning light illuminated. The vehicle was towed to an independent mechanic and the contact was informed that the #1 piston was cracked, engine cooler, P0301 cylinder #1, P219 solenoid failure. The vehicle was taken to another independent mechanic and the engine was replaced. The contact called the local dealer, but the vehicle was not diagnosed or repaired. The manufacturer was notified of the failure, but no further assistance was provided. The failure mileage was approximately 105,102.

on 7/17/21 the piece of the top of the car right from the from window leading to sunroof came undone and flew off while on highway. vehicle was repaired a month later at body shop. this was out of pocket due to not wanting to claim on my insurance due to deductible. This piece flew off at a high velocity with no warning and couldve caused a accident. There was no indication of any issues no lights no warnings signs. There was a loud noise like a brick or large object falling on top which then I heard a lot of air. Recently again in October 5 I was driving on the highway and debris hit my sun roof, my window was shaking and I went to the body shop. in the brief drive there some 10 miles the same plastic part repaired was lifted and coming off. on this occasion I used my Insurance. On 03/2/22, another event in which the plastic portion between front window and rooftop flew off while driving 60mph on the highway.

Panoramic sunroof off centered causing glass to tilt on one side above vehicle. Note, a recall for the same on models 2015 c300 for vehicles with prior service but same issues/ problems for my vehicle that has not been serviced.

Check engine light came on. Code P052E. Had this code in 2018 and the pcv valve and line were changed. Currently has the same issue 3 years later. This is a very common problem with mercedes that have this engine.

The contact owns a 2015 Mercedes Benz C250. The contact had initially received a recall notice for NHTSA Campaign Number: 19V010000 (AIRBAGS). The contact took the vehicle to the local dealer and had the recall serviced. The contact stated that while driving at 35 MPH, another vehicle made a left turn and hit his vehicle in the middle of an intersection. The contact stated that the air bags did not deploy upon impact. The authorities were called to the scene and a police report was filed. No medical attention was rendered at the scene of the accident. The vehicle was towed to an independent mechanic where it remained in their possession. The contact sought medical attention later that day at a local hospital where he was treated for a strain to his left neck and left leg. The dealer nor the manufacturer had yet to be notified of the failure. The vehicle had yet to be repaired. The failure mileage was approximately 60,000.

Hi so i woke up this morning and my started my car as usual then noticed the smell of gas all around the car Inside and out. I got worried turned off the car and started sniffing around to see if i can find where the leak was and found out the high pressure fuel pump was leaking i looked up info on this part and it is very common on these car for that part to fail. Im very upset that there is no recall yet when the dealership told me that they do 2-3 of those jobs a week (HIGH PRESSURE FUEL PUMP REPAIRS) and still no recalls on this,what is it going to take to get one?, my car has to blow up to get your guys attention?? Oh wait other Mercedes c300 cars in the united states already caught on fire please fix this saftey hazard i want to feel safe and not worry about catching on fire. ITS BEEN 6 years AND STILL HAVE NO RECALLS FOR THIS CAR ???

The engine stalled at idle numerous times when at a stop light or stop sign. This was dangerous as the other cars could have ran into my car in anticipation that I should be moving with traffic. The car was taken to the Mercedes Marin dealer service center and diagnostic was done indicating a cracked piston in cylinder one was causing loss of compression and could also cause engine failure at speed if not taken care of. Check engine light DID NOT come on. During research on repairs for this issue, it became apparent that Mercedes Benz is aware of this issue in many of its engines of this model and year, but did nothing to remedy the situation or the underlying manufacturing defect that causes the cracked piston. In addition, Mercedes is unwilling to cover the cost of repair or replacement (car has only. 49,000 miles, but is out of warranty due to age).

The contact owns a 2015 Mercedes-Benz C300. The contact stated while driving 50 MPH, the contact heard an abnormal flapping sound coming from the opened panoramic moon roof. The contact reached up into the open moon roof and discovered that the adhesive bonding on the front panel had started to deteriorate. The contact took the vehicle to the local dealer and was confirmed the failure however, the contact was informed that the dealer was not equipped to perform the repair. The contact was referred to Mercedes-Benz of Wilkes-Barre (150 Motorworld Dr, Wilkes-Barre, PA 18702) where the mechanic removed the bonded panel and installed a new front panel which the contact paid for out of pocket. The first dealer then notified the contact of NHTSA Campaign Number: 21V197000 (Structure) and instructed him to call the dealer where the vehicle was repaired. The second dealer was notified of the failure and informed him to call the manufacturer for potential reimbursement. The manufacturer was notified of the failure and informed him that the vehicle was not included in the recall. The vehicle was repaired. The failure mileage was approximately 68,000.

Panoramic glaaa sunroof mounting bracket made of cheap thin plastic that it breaks easily allowing the panoramic glass roof to fly off the car if driven while open.

The contact owns a 2015 Mercedes-Benz C300. The contact’s wife stated while driving 70 mph, the roof panel separated and detached from the vehicle. The vehicle was diagnosed but not repaired. Upon investigation, the contact associated the failure with NHTSA campaign number: 21V197000 (Structure) however, the part to do the recall repair was not yet available. The manufacturer was informed of the failure but offered no assistance. The failure mileage was approximately 57,000.

Panoramic Sunroof has had several problems previously. While driving 65 mph the plastic roof piece between the windshield and sunroof suddenly and unexpectedly dislodged and flew off the car.

I would like to bring to your attention a potentially dangerous design flaw in my 2015 Mercedes C300. That design flaw resulted in me having to cut the seat belt off a passenger, my wife, in order to free her from the car. I will also explain in detail the admittedly rare circumstances that led to this potentially dangerous incident. In May 2021, my wife underwent outpatient surgery of her left shoulder. After the surgery a nurse brought my wife to the curb in front of the hospital, where I had pulled up my car. The nurse and I assisted my wife with her transfer from the wheel chair into the passenger seat. My wife was wearing a sling supported by a spacing pillow on her left arm. The nurse then proceeded to fasten the seat belt around my wife. Since the nurse’s procedure is of importance to this incident, I will explain it in detail. After my wife was seated, the nurse unwound the passenger seat belt entirely and inserted the belt tongue into the buckle so that the lap part of the seat belt went properly around my wife’s lap. To protect the fresh surgical site from external forces, the nurse then placed the part of the seat belt that is normally worn across the chest BEHIND my wife’s back. Had the seat belt been placed properly across my wife’s chest, it would have been forced to pass over her left arm, which was tied to her body by the sling and bandages. It was thus not possible to wear the chest part of the seat belt properly over the chest but under the left arm. Lastly, the nurse allowed the fully extended seat belt to wind up onto the pretensioner. Upon arrival at home I wanted to take the seat belt off my wife. To this end I opened the passenger door, and gently pulled on the seat belt in order to slacken it enough to get the seat belt off her. However, I could not get any slack. Per instructions in the user manual, I opened the belt buckle but the belt was tightly wound around my wife's body. Ultimately, I had to cut the belt with scissors.

The panoramic sunroof of the C300 is held in plastic hooks that break, even with normal use. So, that leaves the panoramic roof to fly off the vehicle on the highway. I have not opened my roof in three years because I am afraid it might not hold up. Looking at the MB owners' forum, it seems to be a pretty common issue that these plastic hooks break, and then the panoramic roof either doesn't close all the way, stay up to let the air come underneath it to introduce the risk of it flying away, or become really flappy when driving with open roof.

On July the 8th I was driver on interstate highway 65south in Birmingham Alabama in my 2015 Mercedes c 300 when there was a loud thump which startled me and almost caused an accident what happened is the roof panel between the windshield and sunroof flew off it caused damage to my vehicle and almost an accident now when I contacted Mercedes they say that it is a recall out for this problem but they do not have a time as to when this can be fixed this will be a problem because now I am not able to drive my vehicle because there is a gape between the windshield and the roof where water and anything else will get into the vehicle this is terrible now I am without a car for who knows how long.

In March of 2020 I was driving home from work. I stopped at a red light. When it turned green, I proceeded to step on the gas. My car started making noises and shaking as I drove. My check engine light came on. I was able to pull over without incident. My vehicle has under 48k miles on it! I had it towed to a Firestone facility by my house. They replaced spark plugs and ignition coil 1 and 2. They said it was still severely misfiring. Cylinder 1 must have internal damage and should be towed to the dealer. They gave me a spark plug they removed that had significant damage to the top part. They said something must have impacted it with significant force. I then had the vehicle towed to a Mercedes Benz Dealership. They said they inspected with a scope and found piston material missing, can see ring exposed and have damage to cylinder wall. Will need to replace engine, turbo charger, cat converter intake manifold to repair. They wanted $18k to repair. I did some research and found out that the 2015 Mercedes C class was the first year they switched from 6 cylinder to 4 cylinder turbo charge engine. These models have had a significant amount of engine problems and failures, the manufacturer is aware of. Many of these occurred in cylinder 1 along with wrist pins issues and others. I found my situation wasn't unique. I then filed a complaint with The BBB in Georgia. MBUSA offered me $3k towards the repair or purchase of a new vehicle. I declined the offer. I only wanted my vehicle repaired. I wasn't alone in this situation. These issues are easily found online. My vehicle has since been sitting in my driveway for almost a year and a half. I've been making my monthly car and insurance payments on a vehicle I can't drive. I recently went to the Mercedes dealership and they will give me $5k for the vehicle towards a trade, leaving me with $15k negative equity towards the purchase of a vehicle. Mercedes should stand behind their products and do the right thing

Driving down the interstate and half of the stationary roof panel dislodged. Luckily no accidents occurred due to the malfunction. The other half is still loosely attached and I am worried it could cause an accident if it detaches . I have emailed and called headquarters as well as my local dealership and no one has the ability to fix the problem and cannot confirm if I choose to pay out of pocket, that I will be reimbursed. There is a recall and it’s #21V197. At this point I want some sort of solution so I can ensure the safety of myself and those driving around me.

I was in middle line on I-5 SB San Diego doing 40-60MPH when my car suddenly started to shudder, shake and smoke came from the exhaust. The car lost power and the check-engine light came on right away. I was told that Cylinder 3 lost pressure, that the engine wall was damaged and that possibly the piston and wrist pin are cracked. My car has only 66K miles and the Mercedes Benz dealership is telling me that I need a new engine that will cost $19,000. After doing some research I have found out that I wasn't the only one with this issue. I have listed an example here: "HERE IS A MAJOR ISSUE WITH THE 2015 M274 MERCEDES ENGINE REGARDING THE WRIST PINS. MERCEDES HAS ISSUED NUMEROUS INTERNAL SERVICE BULLETINS ABOUT THE ISSUE. THE ENGINES WERE MANUFACTURED WITH WRIST PINS WITH TOO MUCH TOLERANCE THAT SLAP AGAINST THE PISTON WHEN OPERATING THAT COULD LEAD TO PREMATURE ENGINE FAILURES. THERE ARE HUNDREDS OF COMPLAINTS ON ONLINE FORUMS OF PREMATURE ENGINE FAILURES (PRE 100K MILES)." MBUSA requested from me proof that the car was serviced on time and with the correct parts. Once I was able to prove everything they told me that they were sorry but I still need to pay for everything. They did offer a "10% good-will discount". I wish they told me when I was buying a car that after every 6th oil change I will need a new engine. PLEASE MAKE MERCEDES MAKE THIS RIGHT AND FIX THE AFFECTED CARS THE RIGHT WAY.

The contact owns a 2015 Mercedes Benz C300. The contact received notification of NHTSA Campaign Number: 21V197000 (STRUCTURE) however, the part to do the recall was unavailable. The contact stated on June 18, 2021, while driving 55 mph, the roof plastic panel detached and flew into oncoming traffic. The contact stated no one was injured. The contact called the local dealer and was informed that the part was not available. The contact stated that the manufacturer exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the failure. The failure mileage was approximately 59,000. VIN tool confirms part not available.

Sunroof clips are snapping on many w205 2015 mercedes c300 models causing the panoramic roof to come loose potentially flying off the car while driving this has the potential to hurt many people. Mercedes claims there is only a recall for models up to 2011 however hundreds of thousands of later model vehicles have the same issue. I read an article saying they recently opened a recall for the later models but my vin isn’t covered. If the 100 pound panoramic roof flies off while driving on the highway at 70 mph it can definitely kill someone. Please address my concern I cannot afford to come out of pocket for Mercedes defect and lack of help.

My daughter was driving at freeway speeds, when she heard, what we now know, is a portion of the sunroof panel flapping and break off. There was no warning, no instrument indication, and assume the broken part was a safety hazard to vehicles following. We took her vehicle to Fletcher Jones Mercedes in Newport Beach, but they're hesitating about repairing or reimbursing costs, due to the pending nature of the NHTSA Recall #21V197.

Heavy fuel/gasoline smell around engine bay began approximately 2 years ago while the car was still under original 5 year warranty. Fuel smell would persist outside of the vehicle despite the vehicle not being driven for multiple days. When driven, fuel smell would permeate into the cabin of the vehicle and cause mild headaches to the occupants. Taken to dealer to find cause of smell and was advised that there was nothing wrong with the vehicle. Fuel smell continues to persist since it was originally noticed without change and vehicle is no longer within warranty period. Recently, this vehicle was taken back to the same dealer for servicing for an unrelated issue. Told the service representative that there was a fuel smell that continues to linger around the vehicle when parked and inside the cabin. This inspection revealed leaks from two fuel lines and technician recommended replacement. Warning lamps, messages, or other indicators from the car never appeared.

Passenger side airbag light keeps coming on when someone is sitting in the car. My electrical system shuts off and on and goes haywire

check engine light and check oil light came on in rush hour traffic in atlant during rush hour. Car started sputtering and finally made it to the shoulder of the interstate and oil was low on the dip stick. I added oil and a day later same thing. Took it to the dealer and cracked piston in #1 cylinder service guy said about 3 to 6 a day on this year benz.

The contact owns a 2015 Mercedes-Benz C300. The contact stated that the sun roof ceased in the open position. The contact stated that the adhesive on the paneling had deteriorated which caused the sun roof to lose functionality. The vehicle was not taken to the local dealer. Upon investigation, the contact associated the failure with NHTSA Campaign Number: 21V197000 (STRUCTURE) however, the vin was not included. The manufacturer was informed of failure and informed the contact that the vehicle was not included in the recall. The failure mileage was approximately 61,000.

WHILE DRIVING MY 2015 MERCEDES BENZ C300 4MATIC WITH PANORAMIC ROOF ONE DAY ON RTE 9 IN HYDE PARK NY, A 2 LANE STATE ROAD I WAS TRAVELING AT 40 MPH, I SUDDENLY HEARD MORE AIR THAN USUAL AND THEN SECONDS LATER A LOUD FLAPPING NOISE ON ROOF. I PULLED OVER IMMEDIATELY ONLY TO FIND THE STATIONARY ROOF PANEL ALL THE WAY FORWARD ON THE ROOF, (DIRECTLY IN FRONT OF GLASS PORTION OF THE PANO ROOF) BECAME LOOSE ON ONE SIDE AND FLAPPED OPEN WITH WIND WHEN IN MOTION. I USED 3 QUARTERS BETWEEN WINDSHIELD AND SAID PANEL TO HOLD IT FROM POPPING UP WHILE DRIVING AND DROVE IMMEDIATELY TO A BODY SHOP. TBEY INSPECTED IT AND DETERMINED IT WAS HELD DOWN WITH BLACK EPOXY SIMILAR TO WHAT IS USED TO INSTALL GLASS SUCH AS WINDSHIELDS. THEY ADDED SOME EPOXY AND TAPED DOWN THE PIECE FOR ME. APPROXIMATELY ONE WEEK LATER I WAS TRAVELING ON THE SAME ROAD AT ABOUT 30MPH AND SUDDENLY ALL WITHIN LIKE 2 SECONDS HEARD LOUD WIND, THEN FLAPPING, THEN SAW THE ROOF PIECE FLY OFF SWING IN FRONT OFF WINDSHIELD IT WAS STILL ATTACHED TO A RUBBER GASKET, THEN UP IN THE AIR AND BACK DOWN AND SMACKED THE SIDE OF DRIVERS DOOR BEFORE BREAKING FREE AND FLYING DOWN THE ROAD BEHIND ME. LUCKILY IT DID NOT STRIKE ANY CARS OR PEOPLE AS IT BRIEFLY HELD ON TO THE GASKET ATTACHED. I IMMEDIATELY STOPPED AND WAS ABLE TO RETRIEVE IT, BROKEN INTO 2 PIECES. SOME ONLINE RESEARCH FOUND THIS HAS BEEN A VERY COMMON PROBLEM WITH MANY, MANY PEOPLE WHO POSTED ALL OVWR THE INTERNET ON FACEBOOK AND SEVERAL OTHER SITES. I THEN FOUND THE EXACT SAME PROBLEM, AND PART WAS RECALLED BY MERCEDES FOR 10S OF THOUSANDS IF CARS, BUT THE RECALL DID NOT INCLUDE MY YEAR (BUT DID INCLUDE MY MODEL FOR OTHER YEARS). THIS IS VERY OBVIOUSLY THE SAME EXACT PROBLEM AND SHOULD BE COVERED FOR ALL YEARS BY MERCEDES. I CALLED AND AFTER A LENGTHY PHONE CALL WITH MERCEDES BENZ I GOT NOWHERE. THE AGENT FOR MB REFUSED TO EVEN ADMIT IT WAS A RECALL, AND WAS RUDE.

THE C300 4MATIC SPECIFICALLY SHOULD BE RECALLED BECAUSE SOMETHING NEAR THE FRONT END SQUEAKS AND MAKES ALL TYPES OF NOISES

GAS LEAK/ SMELL IN CABIN AT IDLE

THE 7 SPEED TRANSMISSION SHIFTS VERY HARD FROM 1 GEAR TO 2 GEAR TO 3 GEAR. FROM 3 GEAR ALL THE WAY TO 7 GEAR IS VERY SMOOTH. ALSO THE SAME WAY AROUND WHEN YOU DOWNSHIFT FROM 3 GEAR TO 2 GEAR TO 1 GEAR. THE SLOWING DOWN IS VERY HARSH AND IT LOOKS LIKE THE TRANSMISSION DOESN'T UNDERSTAND THAT THE CAR IS GOING TO A FULL STOP. ALL THE POWER AND SPEED CUT DOWN A FEW SECONDS BEFORE FULL STOP. I HAVE PERSONALLY TRIED TO DO THE RESET WITH KEY AND PEDAL TRICK BUT IT ONLY WORKS FOR A DAY OR TWO AND GOES RIGHT BACK TO THE ROUGH SHIFTING.

TL* THE CONTACT OWNS A 2015 MERCEDES BENZ C300. THE CONTACT STATED THAT WHILE OPERATING THE VEHICLE, THE CHECK ENGINE LIGHT REMAINED ILLUMINATED WITH AN ABNORMAL SOUND COMING FROM THE ENGINE. IN ADDITION, WHILE DRIVING THE VEHICLE WOULD NOT PROPERLY ACCELERATE AND UNINTENTIONALLY DECELERATED WHILE SPUTTERING. THE VEHICLE WAS TOWED TO THE LOCAL DEALER MERCEDES BENZ OF WILMINGTON LOCATED AT 3801 LANCASTER PIKE, WILMINGTON, DE 19805 TO BE DIAGNOSED. THE CONTACT WAS INFORMED THAT THE ENGINE WAS FAULTY AND NEEDED TO BE REPLACED. THE VEHICLE WAS NOT YET REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE, BUT NO ASSISTANCE WAS OFFERED. THE FAILURE MILEAGE WAS 80,000.

UPON SUBMITTING A CLAIM FOR MY "INOPERATIVE" SENSOR ISSUE AND THE CAR LOSING ALL POWER AT HIGHWAY SPEEDS. I DISCOVERED YOUR CLAIM ABOUT PANORAMIC SUNROOF DETACHMENTS. WELL YOU ARE IN LUCK AS I HAVE A LOVELY MERCEDES WITH A ROOF PANEL THAT I HAD TO GLUE TO THE TRACK AS IT CAME APART. THE HINGE ON RIGHT SIDE IS LOOSE. I CAN NO LONGER OPEN THE SUNROOF OR IT WILL CATCH WIND AS IF IT'S ABOUT TO DETHATCH. DRIVING THE SUNROOF IS SO LOOSE THAT IT WILL NOT CLOSE WITHOUT THE HELP OF HOLDING IT DOWN SO IT LOCKS INTO PLACE. BROUGHT IT INTO THE DEALER LAST SUMMER AND THEY BRUSHED IT OFF AND TRIED TO CHARGE ME OVER $2,000 TO GET IT FIXED. THEY SAID "COMMON ISSUE" I WOULD PRODUCE PICTURES, HOWEVER MY CAR IS CURRENTLY SITTING AT A MERCEDES FACTORY SHOP GETTING ITS OTHER SAFETY ISSUES TAKEN CARE OF.

ON FEBRUARY 9TH, DURING MY MORNING COMMUTE ON THE INTERSTATE THE CAR LOST POWER TO THE DRIVETRAIN. MESSAGE THAT DISPLAYS WAS "COLLISION ASSIST PLUS INOPERATIVE" ALONG WITH CRUISE CONTROL INOPERATIVE. WITH AN AMBER ESP LIGHT ILLUMINATED, THERE WAS NO ENGINE LIGHT ON. WHEN THIS MESSAGE APPEARED THE CAR WOULD NO LONGER ACCELERATE (LIMP MODE). IN AVOIDANCE TO BEING IN A REAR END COLLISION I QUICKLY PULLED OVER, TURNED OFF THE CAR AND TURNED BACK ON. INOPERATIVE MESSAGE, LIMP MODE AND ESP LIGHT WAS CLEARED. I CALLED DEALER TO NOTIFY. MY THOUGHT WAS THE BATTERY IS A DUD (WAS REPLACED THE DAY PRIOR), THE CAR NEEDS A SOFTWARE REBOOT DUE TO THE NEW BATTERY OR CAR WAS NOT CONNECTED TO THE "MEMORY SAVER" CORRECTLY. OR THE SENSORS WERE DIRTY. SO I DID THE EASIEST. I WASHED THE CAR. THIS PROBLEM CONTINUED TO HAPPEN 5-6 TIMES MORE OVER THE NEXT FEW DAYS STALLING ON THE FREEWAY AT 65-75 MPH. EXTREMELY DANGEROUS & LIFE THREATENING. NO ENGINE PROBLEMS APPARENT. SEEMS TO BE RADAR OR SOFTWARE. THIS IS EXTREMELY DANGEROUS WHILE ON THE HIGHWAY, I FOUND MANY OTHER WITH THIS SAME ISSUE ON NHTSA. I ATTACHED A PICTURE OF CAR SHOWING MESSAGE WITH NO POWER. MY SEATBELT WAS OFF AS I WAS ON SIDE OF ROAD TRYING TO GET TO GAS STATION. THIS ISSUE IS CLEARED BY TURNING CAR ON / OFF. THEN IT HAPPENS AGAIN HOURS OR A DAY LATER, LOSS OF POWER AT HIGHWAY SPEEDS. COAST OVER.

SUSPENSION PARTS ARE RUSTING OUT FAST I DON'T LIVE IN A SALTED ROAD FOR BLACK ICE TYPE OF ENVIRONMENT CAR ONLY HAS 66K MILES AND AC POURS FUEL ODORS IN THE CABIN INTERIOR MATERIALS ARE BUBBLING UP FAST EVEN AFTER UV TREATMENTS.

THERE IS A FUEL HOSE (PARTS NUMBER: 274 070 3500) CONNECT TO THE HIGH PRESSURE PUMP IN FRONT ENGINE AREA. THE FUEL HOSE WAS FASTENED BY A CLAMP (NOT SURE THE PARTS NUMBER) . BECAUSE OF THE DESIGN FLAW, THIS CLAMP WILL LOOSE SINCE IT'S A SNAP JOINT ASSEMBLIES NOT TIGHTEN BY SCREWS. UNDER THIS SITUATION, THE FUEL HOSE WILL LOOSE AND AFFECTED BY THERMAL EXPANSION, THIS PROBLEM WILL CAUSE FUEL LEAK/SEEPING. WE CAN SMELL FUEL NEAR THE PUMP BEFORE WE START CAR IN COLD IN THE MORNING AND THIS SMELL CAN BE SMELLED UNTIL THE ENGINE WORKING INTO THE NORMAL OPERATING TEMPERATURE OR WHEN WE TURN ON THE AC OR HEATER . FUEL IS A VERY CRITICAL SAFETY PROBLEM AND USUALLY WE CANNOT TAKE NOTICE OF THIS POTENTIAL PROBLEM.THIS IS BEEN HAPPENING SINCE 11/19/2019 THE DATE WHEN I BOUGHT THE CAR TILL NOW

CYLINDER ONE CRACKED UNDER NORMAL USE

TL* THE CONTACT OWNS A 2015 MERCEDES-BENZ C300. THE CONTACT STATED THAT THE CHECK ENGINE WARNING LIGHT WAS ILLUMINATED. THE VEHICLE WAS TAKEN TO THE LOCAL DEALER MERCEDES-BENZ OF LOS ANGELES (1801 S FIGUEROA ST, LOS ANGELES, CA 90015, (213)425-3100) AND THE MECHANIC WAS UNABLE TO DUPLICATE THE FAILURE. THE VEHICLE HAD NOT BEEN REPAIRED AS OF YET. THE MANUFACTURER HAD BEEN INFORMED OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 78,000.

THERE IS A MAJOR ISSUE WITH THE 2015 M274 MERCEDES ENGINE REGARDING THE WRIST PINS. MERCEDES HAS ISSUED NUMEROUS INTERNAL SERVICE BULLETINS ABOUT THE ISSUE. THE ENGINES WERE MANUFACTURED WITH WRIST PINS WITH TOO MUCH TOLERANCE THAT SLAP AGAINST THE PISTON WHEN OPERATING THAT COULD LEAD TO PREMATURE ENGINE FAILURES. THERE ARE HUNDREDS OF COMPLAINTS ON ONLINE FORUMS OF PREMATURE ENGINE FAILURES (PRE 100K MILES). I CONTACTED MERCEDES AND THEY REFUSE TO DO ANYTHING TO FIX THIS PROBLEM THE REPAIR IS WELL OVER $8,000 AND THE AVERAGE PERSON JUST CAN NOT AFFORD IT. YOU DIAGNOSE THE PROBLEM BASED ON CHATTER DURING DECELERATION. PLEASE MAKE MERCEDES MAKE THIS RIGHT AND FIX THE AFFECTED CARS THE RIGHT WAY. I JUST BOUGHT THIS CAR AND I AM NOW IN THE HOLE OVER $20,000

EVERY TIME I START MY CAR IT SMELLS LIKE GAS AND IT'S SO STRONG TO THE POINT WHERE IT GIVES ME HEADACHES. ALSO I WAS ON THE FREEWAY AND THE ROADS WERE WET FROM PREVIOUS RAIN AND I ALMOST DIED AND HYDROPLANED ON THE FREEWAY. EVEN IF IT'S A SMALL BIT OF RAIN MY CAR STARTS SHAKING AS IF I DON'T HAVE CONTROL. I DO NOT FEEL SAFE IN THIS CAR AND I JUST GOT THE CAR A MONTH AGO.

INTERMITTENT FUEL LEAK. REAL BAD GAS SMELL IN CABIN COMING THROUGH THE VENTS. DRIVER SIDE, IN BACK, DOWN BETWEEN THE ENGINE AND BODY. THE FUEL LINES ARE PRESSURIZED, SO IT MIGHT ONLY LEAK WHEN THE PRESSURE BUILDS UP. I KEPT GETTING A STRONG GAS SMELL THE GARAGE AFTER PARKING FOR LONG PERIODS.

TL* THE CONTACT OWNS A 2015 MERCEDES-BENZ C300. THE CONTACT STATED THAT WHILE ATTEMPTING TO ACCELERATE FROM A STOP LIGHT, A LOUD SOUND CAME FROM THE ENGINE COMPARTMENT AND THE VEHICLE BEGAN TO VIBRATE AND SHAKE BEFORE STALLING. THE VEHICLE WAS TOWED TO THE LOCAL DEALER KEELER MERCEDES BENZ LOCATED AT 1111 TROY SCHENECTADY RD, LATHAM, NY 12110 WHO DIAGNOSED THAT THE ENGINE WAS FAULTY AND NEEDED TO BE REPLACED. THE CAUSE OF THE ENGINE FAILURE WAS NOT PROVIDED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 48,000. ## VIN PASSED ## MERCEDES-BENZ 2015 C300 AMG ##

I HAVE THE SAME PROBLEM ABOUT STEERING HARDER WHEN ON LOWER SPEED, EVERY OIL LEVEL LOOKS TO BE PERFECT.

WHILE DRIVING ON THE HIGHWAY MY MY MERCEDES BENZ C300 2015 WITH 37000 MILES ,ENGINE BROKE, AND YOU ARE NOT EXPECTING THAT WHEN YOU ARE DRIVING AT 65 MPH. THE MECHANIC IS SAYING IT IS A WRIST PIN AND A CRACKED #1 PISTON AND IT IS A VERY COMMON ISSUE ON THAT CAR AND MERCEDES REFUSES TO RECALL OR FIX THE PROBLEM IM GOING TO LEAVE A LINK WITH ONE OF THE MANY WEBPAGES WITH AL LOT OF PEOPLE COMPLAINING ABOUT THAT PROBLEM. THANK YOU. HTTPS://MBWORLD.ORG/FORUMS/C-CLASS-W205/731642-W205-C300-STAY-AWAY-PISTON-CRACKED-65-K-MILES.HTML

GAS LEAK IN FUEL LINE, WHILE RECEIVING AN OIL CHANGE FROM A LICENSED MECHANIC, HE BROUGHT TO MY ATTENTION THAT, THERE WAS FUEL LEAKING FROM THE FUEL LINE AND SHOWED (FUEL LINE SOAKED WITH GASOLINE DIRECTLY UNDER THE ENGINE), I ALSO NOTICED THAT WHEN USING THE AC THE STRONG SMELL OF GASOLINE COMES THROUGH THE VENTS.

THIS CAR LEFT ME STRANDED ON THE SIDE OF THE ROAD. THE CAR WAS ON WORKING FINE DRIVING ALONG THEN ALL OF A SUDDEN PUSHING THE GAS PEDAL DID NOTHING AND THE CAR WOULD NOT MOVE. THE ENGINE SHUT OFF COMPLETELY. THE ENGINE WAS NOT GETTING GAS. THE ELECTRICAL AND EVERYTHING ELSE WAS ON IN THE CAR EXCEPT THE ENGINE. THE SYSTEM IN THIS CAR HAS A DOUBLE FUEL TANK THAT ONLY WORKS ON ONE SIDE. THE ENTIRE FUEL SYSTEM IS FAULTY. THE MANAGER AT MERCEDES TOLD ME HIMSELF THAT THIS IS A DESIGN FLAW IN THIS CAR. THERE IS NO REASON WHY A CAR WITH 24,000 MILES SHOULD HAVE BROKEN DOWN ON THE SIDE OF THE ROAD BECAUSE THE ENTIRE FUEL SYSTEM DOES NOT WORK. FAULTY AND HORRIBLE WORKMANSHIP ON A SUPPOSED LUXURY VEHICLE.

SUNROOF NO LONGER CLOSED SHAKES AND RATTLES, SEEMS LIKE A SAFETY ISSUE DURING A POSSIBLE ROLLOVER

WHILE DRIVING MY 2015 C250 COUPE, I HAD TO BRAKE HARD AS I WAS TRYING TO AVERT STOPPED HEAVY TRAFFIC. WHEN I SLAMMED ON THE BREAKS, THE STEERING WHEEL, COLUMN AND ENTIRE VEHICLE LOCKED UP. I WAS UNABLE TO TURN THE WHEEL ENTIRELY. AS A RESULT, MY VEHICLE SLIDE INTO ANOTHER VEHICLE FROM BEHIND. BECAUSE BOTH THE STEERING AND BRAKES LOCKING, I WAS UNABLE TO MANEUVER THE VEHICLE TO AVOID THE STOPPED TRAFFIC. THE AIRBAGS ALSO DID NOT DEPLOY AS THEY SHOULD HAVE.

I CAN SMELL FUEL NEAR THE PUMP BEFORE WE START CAR IN COLD IN THE MORNING AND THIS SMELL CAN BE SMELLED UNTIL THE ENGINE WORKING INTO THE NORMAL OPERATING TEMPERATURE. FUEL IS A VERY CRITICAL SAFETY PROBLEM AND USUALLY WE CANNOT TAKE NOTICE OF THIS POTENTIAL PROBLEM.

THERE ARE NO OPEN OR PENDING RECALLS ON THIS VIN. FOR CONSIDERATION OF ANY PART THAT IS OUT OF MANUFACTURER WARRANTY, IT WILL FIRST NEED TO BE ASSESSED AT THE DEALERSHIP LEVEL. IF FURTHER ASSISTANCE MAY BE REQUIRED, YOU CAN THEN CONTACT THE CUSTOMER ASSISTANCE CENTER FOR FURTHER REVIEW BY AN EXECUTIVE REFERRAL MANAGER. THERE ARE MANY FACTORS IN DETERMINING ANY CONSIDERATION WHICH INCLUDE BUT ARE NOT LIMITED TO THE VEHICLE HISTORY, MILES, TIME OUT OF WARRANTY, CUSTOMER PAY, ETC. PLEASE BE ADVISED THAT THERE IS NO GUARANTEE THAT ASSISTANCE WILL BE PROVIDED, BUT YOU WOULD RECEIVE A CALL WITHIN ONE BUSINESS DAY AT THE NUMBER YOU PROVIDE. 2015 C300 4MATIC PANORAMIC SUNROOF FRONT PANEL DETACHMENT WHILE DRIVING. THE GLASS FLEW OFF AND INTO TRAFFIC WHILE I WAS DRIVING ON INTERSTATE HIGHWAY I-25. I LIVE IN COLORADO SPRINGS CO. USA. AND MAINTENANCE AT THE LOCAL MERCEDES BENZ THERE. QUESTION IS IF THERE IS ANY VISIBILITY TO THIS ISSUE VIA MERCEDES BENZ CORPORATE, AND IF ASSISTANCE ON REPAIRS ARE A REALISTIC EXPECTATION. FAILURE DATE: 08/25/2020 THE CONTACT OWNS A 2015 MERCEDES-BENZ C300. THE CONTACT STATED THAT WHILE DRIVING AT THE SPEED LIMIT ON I-25, THE FRONT GLASS PANEL DETACHED FROM THE VEHICLE. THE CONTACT STATED A TRUE REALIZATION OF THE ISSUE WAS NOT FULLY COMPREHENDED WHEN IT HAPPENED OUTSIDE OF THE NOISE IT MADE AT THE TIME OF FAILURE, UNTIL THE CONTACT PULLED OVER ONCE OFF THE HIGHWAY, AND CONFIRMED THAT THE GLASS PANEL HAD DETACHED FROM THE VEHICLE. THE GLASS PANEL WAS NOT RETRIEVED. THE CONTACT REFERENCED NHTSA CAMPAIGN NUMBER: 19V918000 (VISIBILITY) AS A POSSIBLE SOLUTION FOR THE FAILURE, THE FAILURE MILEAGE WAS APPROXIMATELY 70123. IS ASSISTANCE FOR THE MONETARY COST OF REPAIR AN OPTION.

WHEN DRIVING ON THE BRIDGE THE PIECE OF MY SUNROOF FLEW OFF I PULLED OVER IT WAS RAINING AND THE INSIDE OF MY CAR GOT WET THE MOTOR ON MY SUNROOF NO LONGER WORKS AS THE WATER LEAKED THROUGH. I PICKED UP AS MUCH OF THE PIECES AS I COULD BUT THE PART WAS RUN OVER.

2015 MERCEDES BENZ C300.

THE CONSUMER STATED THE VEHICLE WAS PURCHASE WITH THE USE OF THE VOICE COMMAND AND IT SHOULD REMAIN. *JS

I STARTED EXPERIENCING LOUD WIND NOISE COMING FROM THE TOP OF MY CAR NEAR MY WINDSHIELD WHEN DRIVING OVER 40MPH. I PULLED OVER AND EXAMINED THE AREA AND FOUND THAT THE TOP LEFT GLASS PANEL IN FRONT OF THE SUNROOF ON MY 2015 MERCEDES BENZ C300 WAS SLIGHTLY PROPPED UP. IT SEEMED TO BE A POSSIBLE SEAL OR GLUE ISSUE CAUSING THE GLASS PANEL TO BE SLIGHTLY LOOSE AND ALLOWING AIR IN. I CALLED MERCEDES AND MADE THE NEXT AVAILABLE APPOINTMENT FOR SERVICE A FEW DAYS OUT. WHILE DRIVING ON THE FREEWAY, I BEGUN TO HEAR THE WIND NOISE AGAIN BUT FOLLOWED BY A LOUD RIP FROM THE ROOF OF MY CAR THIS TIME BUT DID NOT SEE ANYTHING IN SIGHT. WHEN I PULLED OVER, THE GLASS PANEL WAS COMPLETELY MISSING AND WENT FLYING SOMEWHERE ON THE HIGHWAY, CAUSING A ROAD HAZARD. IT WAS TORN OFF THE CAR AND THE ROOF OF THE CAR IS NOW EXPOSED.

I TOOK MY CAR IN FOR A MULTI POINT INSPECTION AT THE END OF NOVEMBER 2019 TO MERCEDES OF BELLEVUE. I BEGUN SMELLING GASOLINE FROM THE INSIDE CABIN OF MY CAR A FEW DAYS AFTER THE SERVICE AND HAD TO TAKE THE CAR BACK TO THE DEALERSHIP. THEY FOUND THAT FUEL HOSES GOING TO THE HIGH PRESSURE FUEL PUMP TO BE LEAKING FUEL. WITH THIS BEING A POTENTIAL FIRE HAZARD AND A SAFETY ISSUE, I ARGUED WITH THE DEALER THAT IT SHOULD BE COVERED UNDER WARRANTY, WHICH I STILL HAD A CPO WARRANTY FROM PURCHASING THE VEHICLE FROM THIS SPECIFIC DEALERSHIP. I DID SOME RESEARCH ONLINE AND FOUND THAT, THIS IS A VERY COMMON ISSUE WITH MY VEHICLE MODEL, 2015 MERCEDES BENZ C300. I AM UNSURE WHY THIS ISSUE IS NOT YET RECALLED BY THE MANUFACTURER OR WHY THE DEALERSHIP DID NOT HONOR THIS ISSUE TTO BE COVERED UNDER WARRANTY.. AS A CONCERNED CUSTOMER OF THE HAZARDOUS POSSIBILITIES A FUEL LEAK COULD CAUSE, I STILL MOVED FORWARD WITH PAYING FOR THE REPAIR OUT OF POCKET VERSUS CONTINUING TO DEBATE WITH THE FINANCE AND SERVICE PERSONNEL THAT IT SHOULD BE COVERED UNDER WARRANTY THAT I STILL HAD AT THE TIME.

THE VEHICLE WAS THANKFULLY NOY IN MPTION WHEN MY PANARAMA SUNROOF AND THE SHADES FAILED. THE SHADES I UNDERSTAND ITS NOT A SAFETY PROBLEM, BUT THE SUNROOF NOT BEING ABLE TO HOLD IN PLACE AS IT OPENS IS DIFFERENT. WHEN THE SUNROOF OPENED, THE REAR OF THE ROOF WAS NOT IN PLACE AND SHAKY. WHEN I TRIED TO CLOSE, IT HAD NOT LOCKED ITSELF RIGHT BACK IN PLACE, WHERE I HAD TO TAKE IT TO A MECHANIC JUST TO HAVE IT SHUT TO AVOID THE RAINSTORM YESTERDAY. I RECENTLY DID SOME RESEARCH AND READ THROUGH SOME ARTICLES, HAD A FRIEND OF MINE TAKE A LOOK AT IT AND IT SEEMS TO BE VERY SIMILAR, ALMOST THE SAME AS THE RECALL THEY HAVE DONE ON OTHER YEAR MAKE FOR THE PANARAMA ROOF.

FRONT OF GLASS SUNROOF FLEW OFF WHILE DRIVING ON FREEWAY - RECALL EXISTS FOR OLDER VERSIONS OF MY CAR. MINE IS A 2015

ON JULY 19, 2020, I WAS DRIVING MY MB C300, ON HIGHWAY 301 IN BRADENTON FLORIDA. SUDDENLY, I HEARD WHAT SOUNDED LIKE A GUNSHOT. I WAS TERRIFIED. ONCE, I CALMED DOWN AND WAS ABLE TO GET TO A SAFE LOCATION, UPON EXAMINATION, I DISCOVERED THAT MY SUNROOF HAD SPONTANEOUSLY SHATTERED. THERE WAS ABSOLUTELY NO EVIDENCE OF ANY TYPE OF FOREIGN OBJECT CAUSING THE SUNROOM TO SHATTER. FORTUNATELY, WHEN THE LOUD BANG OCCURRED, I HAD THE PRESENCE OF MIND TO NOT LOSE CONTROL OF MY CAR IN WHAT COULD HAVE CAUSED AN ACCIDENT. ALSO, IF THE SUNROOF HAD BEEN PARTIALLY OPENED THE GLASS CHARDS COULD HAVE CAUSED SIGNIFICANT INJURY. THIS IS COMPLETELY AND UTTERLY UNACCEPTABLE. MERCEDES BENZ IS A LUXURY CAR MANUFACTURER, KNOWN FOR SUPERIOR ENGINEERING. THIS SHOULD NOT HAVE HAPPENED, UNDER ANY CIRCUMSTANCES.

THERE'S FUEL SMELL COMING INTO THE CABIN. BROUGHT IT INTO MERCEDES DEALER SERVICE CENTER AND THEY SAID IT'S 2 BROKEN FUEL LINE. IT'S A COMMON ISSUE WITH THIS GENERATION C CLASS BUT THEY REFUSE TO FIX IT UNDER WARRANTY.

CRANKCASE BREATHER HOSE IS LEAKING FUEL. FUEL LINE IS LEAKING FUEL. THIS CREATES GAS SMELL IN THE CAR. THIS IS ALSO UNSAFE DUE TO THE FUEL LEAKAGE. LOOKS LIKE THIS IS A VERY COMMON PROBLEM ON THESE CARS. IT SHOULD BE A RECALL.

SUN ROOF FIX GLASS FLEW OFF OF VEHICLES IN TRAFFIC WHILE I WAS DRIVING ON A BUSY HIGHWAY. ADHESIVE GLUE FAILED TO KEEP THE PART ATTACHED.

I WAS DRIVING ON 02/13/2020, ABOUT TO CROSS THE ARKANSAS/TENNESSEE BRIDGE WHEN MY SUNROOF EXPLODED WITHOUT AN EXPLANATION. THE ENTIRE PANORAMIC SUNROOF SHATTERED. IT WAS THE MOST FRIGHTENING THING I HAVE EVER EXPERIENCE. IF MY SUNROOF SCREEN HAD BEEN OPEN, ALL OF THE GLASS WOULD HAVE FALLEN ON MY HEAD AND IN MY EYES. CALLED THE MB DEALER FOR HELP, THEY WEREN'T WILLING TO HELP AND SUGGESTED THAT I FILE IT WITH MY OWN INSURANCE COMPANY. THIS IS A DEFECT OF MB!!

PISTON CRACKED AT 68,000 MILES, CAUSING ENGINE DAMAGE THAT CANNOT BE REPAIRED.

THE VEHICLE HAS 67K MILES. I NOTICED A GASOLINE ODOR COMING FROM THE AC A MONTH AGO SINCE THEN, THE ODOR INTENSITY HAS DRASTICALLY INCREASED. THE ODOR USUALLY GOES AWAY AFTER A FEW MILES, HOWEVER, TODAY THE ODOR DID NOT GO AWAY AND I NOTICED AN ONSET OF A HEADACHE SINCE COMMENCING THE DRIVE, I THEN BECAME VERY DROWSY AND WAS VERY CLOSE TO REAR-ENDING THE VEHICLE IN FRONT OF ME ON THE WAY HOME, BUT THANKFULLY THE COLLISION WARNING SYSTEM EMITTED A LOUD SOUND AND I WAS ABLE TO REACT IN TIME TO PRESS THE BRAKES AND AVOID THE COLLISION. THERE WAS A RECALL ON 3/10/2015 FOR VEHICLES MANUFACTURED BETWEEN APRIL 7, 2014, AND JULY 25, 2014, FOR AN ISSUE WITH THE FUEL DELIVERY MODULE AND THE TANK, MY VEHICLE WAS MANUFACTURED JANUARY 2015, HOWEVER, I BELIEVE THE SAME ISSUE IS CAUSING THE GASOLINE FUMES I HAVE BEEN EXPERIENCING IN MY VEHICLE AC SYSTEM.

GAS SMELL COMING FROM CABIN EVERY TIME I PUT HEAT ON ,COME TO FIND OUT DEALERSHIP INFORMED ME THERE WAS A LEAK ON GAS HOSE AND NOT COVERED BY THE WARRANTY I HAVE, ONLY HAD THE CAR FOR A YEAR DIDN'T DRIVE MY CAR IN FEAR WILL EXPLODE PLUS IM A SMOKER SO I COULD OF HAVE BLOWN UP, PLUS BATTERY THEY SAID WAS WEAK NEEDS TO B REPLACE ,AGAIN I BARELY DRIVE AND ONLY HAD MY CAR FOR A YEAR CPO EVERYTHING SHOULD OF BEEN NEW AND RUNNING PERFECT

GAS SMELL COMING FROM THE ENGINE WHEN STARTING THE CAR. THE GAS SMELL GOES AWAY BUT COMES BACK EVERYTIME I START THE CAR.

2015 MERCEDES BENZ C300 WITH 65 K MILES. THE SECONDARY HIGH PRESSURE FUEL PUMP (274070050180) LEAKED GAS SERIOUSLY. IT WAS THE UNIT ITSELF NOT THE CONNECTIONS OR LINES TO IT.

A FEW DAYS AGO, I BEGAN SMELLING A STRONG SMELL OF GASOLINE WHEN I DROVE MY CAR. THIS WENT ON FOR SEVERAL DAYS, SO I TOOK MY CAR INTO THE DEALERSHIP. AS SOON AS I DESCRIBED MY PROBLEM TO THE SERVICE STAFF AND BEFORE THEY CHECKED ME IN, THEY ASKED ME IF THE MODEL WAS A MERCEDES C300. WHEN I REPLIED THAT IT WAS, THEY SAID THAT THEY HAD SEEN THIS PROBLEM QUITE OFTEN ON THIS MODEL. GIVEN THE LOW MILEAGE OF 23,115 MILES ON MY CAR, A FUEL LINE LEAK WOULD NOT NORMALLY BE EXPECTED TO OCCUR. CONSIDERING THAT FACT ALONG WITH THE REPORTED COMMONALITY OF THIS ISSUE, I AM CONCERNED THAT, FOR OTHER DRIVERS WITH THIS POTENTIAL PROBLEM, THE SYMPTOMS MAY INVOLVE MORE THAN JUST THE SCENT OF GASOLINE AND RESULT IN CAR FIRES OR ACCIDENTS. NEITHER THE DEALERSHIP NOR CORPORATE MERCEDES HAVE BEEN RESPONSIVE TO MY CONCERNS.

TL* THE CONTACT OWNS A 2015 MERCEDES-BENZ C300. THE CONTACT STATED THAT THE ENGINE HAD BEEN SHUTTING OFF EVER SINCE THE VEHICLE WAS PURCHASED IN 2016. IN ADDITION, SEVERAL UNKNOWN WARNING INDICATORS WOULD ILLUMINATE FOR NO REASON.

MERCEDES-BENZ OF AUSTIN (6757 AIRPORT BLVD, AUSTIN, TX 78752, (512) 220-0940) CALLED THE OTHER DEALER AND INFORMED THEM NOT TO REPAIR THE VEHICLE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 20.

FUEL SYSTEM, GASOLINE. THERE IS A FUEL SMELL COMING INSIDE OF THE CAR THROUGH THE FRONT FILTERS. WE HAVE CHANGED FUEL INJECTOR RING HOWEVER THE SMELL IS STILL THERE. MERCEDES DEALER IS NOT WILLING TO DO ANYTHING ABOUT THIS. I SEE THERE ARE RECALLS ON THE SAME MODELS PRODUCED A YEAR PRIOR. BELIEVE THIS MIGHT BE THE SAME ISSUE THAT WAS NOT RESOLVED . NHTSA CAMPAIGN ID: 15V138000 ## VIN PASSED ## MERCEDES-BENZ C300 2015 ##

BOUGHT USED MERCEDES C300 2015 4MATIC ON FEB'2019, ODOMETER READING WAS 44K MILES WITH CLEAN CARFAX REPORT. AFTER DRIVING JUST ABOUT 7K MIKES MORE, AT 53K MIKES CAR SHOWS ENGINE WARNING. THIS IS UNFORTUNATE FROM MERCEDEZ THAT WITH THIS MUCH OF NIRMAL USE, CAR IS HAVING ENGINE ISSUES.

GASOLINE FUEL HOSE LEAK BETWEEN THE ENGINE AND THE DRIVER SIDE CAUSING A STRONG GASOLINE SMELL INSIDE THE CABIN AND UNDER THE HOOD WHEN THE CAR IS RUNNING AND CAUSING A FIRE HAZARD

WHILE I WAS TRAVELLING ON HIGHWAY, I GOT AN ALERT ABOUT COLLISION SYSTEM BEING INOPERABLE, I TOOK MY CAR TO THE DEALERSHIP, IT WAS INVESTIGATED AND WAS TOLD TO ME THAT I HAD AN ACCIDENT? I DID NOT. I AM THINKING IT WAS SOME KIND OF AN ELECTRICAL/RADAR SENSOR ISSUE? IT DID NOT AFFECT MY SPEED OR ABILITY TO ACCELERATE

WHILE THE VEHICLE IN MOTION, HEARING A LOUD SOUNDS COMING FROM THE ENGINE. AT FIRST IT'S SOUNDED LIKE A ROCK IN A TIN CAN, LATER IT WAS A SLAPPING SOUND. ABOUT 10 MINUTES LATER FINALLY GOT OFF THE HIGHWAY AND TURNED IN TO MY NEIGHBOR HOOD. AT THE LAST RIGHT TURN, THE CAR SEIZED UP. TRIED TO RESTART NOTHING HAPPENED. GOOD THING IT WAS AROUND 11PM THERE WAS NO TRAFFIC OR AS MANY CARS ON THE ROAD. IF IT WERE IT COULD PROBABLY JUST STOP ON THE MIDDLE OF THE HIGHWAY. THE CAR IS AT THE DEALERSHIP AND SAYING IT NEEDS A NEW ENGINE, COSTING ABOUT 13K. WHICH IS ABSOLUTELY RIDICULOUS, THERE WAS NO SIGNS OF ENGINE PROBLEM, ENGINE LIGHT WASN'T ON. OUT OF NO WHERE, ENGINE LOCKED UP AND I HAD TO PUSH IT HOME.

BACK DRIVER SIDE SEAT BELT HARD TO ENGAGE AND WILL COME UNENGAGED WITHOUT PROMPTING. BRAKE PADS WEAR OUT EVERY 30,000 MILES BACK PASSENGER SIDE TIRE AND VALVE HAS BEEN REPLACED 4 TIMES IN LESS THAN 70,000 MILES AND STILL LOOSES AIR INTERMITTENTLY. CAR CAN BE PARKED OR MOVING. NO CONSISTENCY IN WHEN OR AMOUNT AIR PRESSURE IS LOST.

STRONG FUEL SMELL IN THE GARAGE AND INSIDE THE VEHICLE DURING COLD START AFTER THE VEHICLE IS PARKED FOR 8-12 HOURS. THE ISSUE IS EVEN MORE NOTICEABLE DURING COLDER WEATHER (BELOW 40). THE DEALER ACKNOWLEDGED THIS IS A COMMON ISSUE FOR C300 AND IS DUE TO A DEFECTIVE CLAMP ON A FUEL LINE. THE VEHICLE IS AT 44,000 MILES AND 6 MOUNTS OUT OF WARRANTY. THE FUEL LEAK IS A SAFETY ISSUE AND SHOULD BE REPAIRED BY THE MANUFACTURER ESPECIALLY IF IS A WELL KNOWN DEFECT.

TL* THE CONTACT OWNS A 2015 MERCEDES-BENZ C300W4. WHEN THE CONTACT ENTERED THE VEHICLE, HE NOTICED A FUEL ODOR.

THE CONTACT TOOK THE VEHICLE TO MERCEDES-BENZ OF PARAMUS (755 NJ-17, PARAMUS, NJ 07652, (201) 977-6365) AND WAS INFORMED THAT THE FUEL HOSE AND THE FUEL LINE NEEDED TO BE REPLACED.

TL* THE CONTACT OWNS A 2015 MERCEDES-BENZ C300W4. WHEN THE CONTACT ENTERED THE VEHICLE, SHE NOTICED A STRONG ODOR OF FUEL. THERE WERE NO WARNING INDICATORS ILLUMINATED. THE VEHICLE WAS TAKEN TO MERCEDES-BENZ OF FARMINGTON (555 N BOURNE CIR, FARMINGTON, UT 84025, (801) 447-3300) WHERE IT WAS DIAGNOSED THAT THE FUEL PUMP WAS FAULTY AND NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND OFFERED A 20% DISCOUNT TOWARDS THE REPAIR COST. THE CONTACT WAS INFORMED TO CALL NHTSA TO FILE A COMPLAINT.

TL* THE CONTACT OWNS A 2015 MERCEDES-BENZ C300. WHILE THE CONTACT'S DAUGHTER WAS DRIVING AT AN UNKNOWN SPEED, THE VEHICLE FAILED TO ACCELERATE AND BEGAN TO HESITATE. IN ADDITION, THE CHECK ENGINE WARNING INDICATOR ILLUMINATED. THE DRIVER WAS ABLE TO PARK ON THE SIDE OF THE ROAD. THE VEHICLE WAS TOWED TO MERCEDES-BENZ OF STEVENS CREEK (LOCATED AT 4500 STEVENS CREEK BLVD, SAN JOSE, CA 95129, (408) 641-4610) WHERE IT WAS DIAGNOSED THAT THE ENGINE NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED. THE FAILURE MILEAGE WAS 58,000.

THERE IS A FUEL HOSE (PARTS NUMBER: 274 070 3500) CONNECT TO THE HIGH PRESSURE PUMP IN FRONT ENGINE AREA. THE FUEL HOSE WAS FASTENED BY A CLAMP (NOT SURE THE PARTS NUMBER) . BECAUSE OF THE DESIGN FLAW, THIS CLAMP WILL LOOSE SINCE IT'S A SNAP JOINT ASSEMBLIES NOT TIGHTEN BY SCREWS. UNDER THIS SITUATION, THE FUEL HOSE WILL LOOSE AND AFFECTED BY THERMAL EXPANSION, THIS PROBLEM WILL CAUSE FUEL LEAK/SEEPING. WE CAN SMELL FUEL NEAR THE PUMP BEFORE WE START CAR IN COLD IN THE MORNING AND THIS SMELL CAN BE SMELLED UNTIL THE ENGINE WORKING INTO THE NORMAL OPERATING TEMPERATURE. FUEL IS A VERY CRITICAL SAFETY PROBLEM AND USUALLY WE CANNOT TAKE NOTICE OF THIS POTENTIAL PROBLEM.

TAKARA RECALL

TL* THE CONTACT OWNS A 2015 MERCEDES-BENZ C-300. THE CONTACT STATED THAT WHILE DRIVING APPROXIMATELY 30 MPH. A POLICE OFFICER HAD PULLED OVER ANOTHER VEHICLE AHEAD ON THE RIGHT SIDE OF THE ROAD. THE VEHICLE IN FRONT MADE A COMPLETE STOP. AS A RESULT, IN TRANSITIONING THE FAR LEFT LANE THE CONTACT REAR ENDED THE VEHICLE IN AN ATTEMPT TO AVOID THE POLICE OFFICER AS HE WAS GOING DOWN TO COMPLETE AN INSPECTION ON THE UNDERBELLY OF THE DUMP TRUCK. THE CONTACT MENTIONED THAT NONE OF HER SAFETY SENSORS (SIDE OR FRONT RESPONDED) INDICATING THAT SHE WAS NEAR A VEHICLE ILLUMINATED. THE STEERING WHEEL AIRBAG DEPLOYED UPON IMPACT. THE KNEE AIR BAG DEPLOYED AFTER THE IMPACT OF THE CRASH. AS THE KNEE AIR BAG WAS DEPLOYING WITH FORCE CAUSED THE CONTACTS RIGHT FOOT TO GET STUCK AND BONES TO CRACK RESULTING IN VARIOUS BREAKS IN HER RIGHT FOOT. THE ELECTRICAL SYSTEM SHUT DOWN AND THE CONTACT WAS UNABLE TO START OR ADJUST HER SEAT IN ORDER TO RELEASE HER FOOT FROM THE KNEE AIR BAG AS PRESSURE WAS BUILDING UP IN THE BAG . THE VEHICLE WAS TOWED TO AN IMPOUND LOT. A POLICE REPORT WAS FILED. THE CONTACT WAS TRANSPORTED TO THE HOSPITAL VIA AMBULANCE WHERE SHE WAS TREATED FOR HER FRACTURED RIGHT FOOT. IT WAS UNKNOWN IF THE DEALER OR THE MANUFACTURER WERE CONTACTED. THE FAILURE MILEAGE WAS 100,000.*TT *JB

AREA UNDER STEERING COLUMN IS EXPOSED REVEALING ELECTRICAL WIRING WHICH APPEARS TO BE CONNECTED TO THE ENGINE OR SOMETHING UNDER THE HOOD. I WAS TOLD THAT'S THE WAY VEHICLE WAS MADE, NO PART OR OPTION TO COVER EXPOSED AREA. IT IS UNSAFE BECAUSE AS I AM DRIVING ON HIGHWAY, CITY STREETS, ETC., MY KNEES TOUCH THE AREA AND MAY JARR SOMETHING LOSE.

AT HIGHWAY DRIVING SPEEDS IN EXCESS OF 50 MPH, THE GLASS TRIM PANEL OF THE PANORAMIC SUNROOF VIBRATES AND FLAPS WILDLY. IT IS NOT SECURELY ATTACHED TO THE ROOF OF THE CAR. I TOOK IT TO THE DEALER TO HAVE IT REPLACED. IT WILL FLY OFF AND HIT THE VEHICLE BEHIND ME. IF THE VEHICLE BEHIND ME WERE A MOTORCYCLE, THE RESULTS WOULD BE DISASTROUS.

CAR LOOSES SPEED WHILE DRIVING IN THE STREET OR A HIGHWAY. NO CODE HAVE BEEN DETECTED IN THE COMPUTER. I HAVE BEEN TAKING THE CAR TO THE DEALERSHIP BUT THEY HAVEN'T FOUND WHAT'S THE PROBLEM.

12/6/17 AIRBAG FRONTAL,8/31/17 ELECTRIAL SYSTEM STARTER ASSEMBLY,8/31/17 ENGINE AND ENGINE COOLING ENGINE,4/21/17 ELECTRICAL SYSTEM SOFTWARE AND 4/21/17 AIRBAG FRONTAL SENSOR/CONTROL MODULE.RECALL ON THESE PARTS.

I SMELLED FUEL IN MY GARAGE OCCASIONALLY FOR THE PAST 4 MONTHS. I ASSUMED IN WAS THE GAS HEATER BUT WHEN I PARK MY CAR IN OTHERS GARAGE I SMELLED FUEL. A FRIEND SUGGESTED IT MIGHT BE MY CAR. I TOOK MY CAR INTO SERVICE FOR MY 50K SERVICE AND ASKED IF THEY COULD LOOK INTO. MERCEDES BENZ INFORMED ME IT IS WET AROUND THE FUEL HOSE CONNECTOR. BEFORE I ONLY SMELLED IT TWICE A MONTH IN THE GARAGE. AFTER ONE I GOT IT BACK FROM SERVICE, I SMELLED FUEL INSIDE THE CAR WHILE I'M DRIVING.

THE FRONT DRIVERS SIDE SUSPENSION SQUEAKS WHEN WHEEL IS TURNED OR GOING OVER BUMPS. THIS CAR IS LESS THAN 5 YEARS OLD AND AROUND 50K MILES. I AM HOPEFUL THIS IS NOT A DANGEROUS FLAW IN THE SUSPENSION SYSTEM.

TL* THE CONTACT OWNS A 2015 MERCEDES-BENZ C350. THE CONTACT RECEIVED NOTIFICATION OF NHTSA CAMPAIGN NUMBER: 19V010000 (AIR BAGS). THE CONTACT STATED THAT THE MANUFACTURER EXCEEDED A REASONABLE AMOUNT OF TIME FOR THE RECALL REPAIR. MERCEDES-BENZ OF DELRAY (1001 LINTON BLVD, DELRAY BEACH, FL 33444, (561) 291-6095) WAS CONTACTED AND CONFIRMED THAT THE PARTS WERE NOT AVAILABLE FOR THE RECALL REMEDY. THE MANUFACTURER WAS MADE AWARE OF THE ISSUE AND WAS NOT ABLE TO CONFIRM WHEN THE PARTS WERE TO BECOME AVAILABLE. THE CONTACT HAD NOT EXPERIENCED A FAILURE. THE VIN WAS UNKNOWN.

MY CAR RECEIVED THE CALL MESSAGE OF POTENTIAL AIRBAG HAZARD IN JANUARY, WHICH WOULD LEAD TO DEATH IF THE AIRBAG POPPED UP. HOWEVER, I HAVE NOT BEEN REPLACED IN BANZ STORE FOR FOUR MONTHSIF THERE IS A SUDDEN ACCIDENT, THE AIRBAG WILL POP UP AND KILL PEOPLE. I WOULD LIKE TO COMPLAIN ABOUT SUCH A SERVICE. A DELAY OF ONE DAY IS VERY LIKELY TO CAUSE AN ACCIDENT

AT COLD START, ESPECIALLY WHEN THE HEATER IS ON, THE CABIN SMELLS OF RAW GASOLINE. THE ISSUE IS QUITE ANNOYING AND EXTREMELY DANGEROUS. AFTER PERFORMING A GOOGLE SEARCH ABOUT THE PROBLEM, I'VE NOTICED THAT OTHERS WHO OWN W205 HAVE EXPERIENCED THIS PROBLEM. THIS IS JUST ONE EXAMPLE OTHERS' COMPLAINTS: HTTP://M.CARCOMPLAINTS.COM/MERCEDES-BENZ/METRIS/2016/FUEL_SYSTEM/FUEL_PROPULSION_SYSTEM.SHTML

ENGINE BROKE A PISTON AT 53,000 MILES IN NORMAL USE. CAUSING MAJOR RUPTURE ON ENGINE.

WHEN ACCELERATING WITH MY MERCEDES C300, THE CAR IS ACTUALLY LOOSING POWER. THE EFFECT IS REINFORCED AS THE CONTROLLING SYSTEM IS BLOCKING THE ACCELERATION. RESULT IS THAT THE CAR IS BRAKING SUDDENLY INSTEAD OF ACCELERATING. IT IS PARTICULARLY DANGEROUS WHEN TRYING TO PASS ANOTHER CAR ON THE HIGH WAY AS THE CAR WILL BRAKE. I ALMOST EXPERIENCED TWICE AN ACCIDENT ON THE HIGHWAY DUE TO THIS ACCELERATION/BAKE ISSUE. I BROUGHT MY CAR TO AN INDEPENDENT MERCEDES REPAIR CENTER. THEY CONFIRMED TO ME THAT MERCEDES ISSUED A TECHNICAL BULLETIN FOR AN ELECTRICAL CABLE REPLACEMENT DUE TO THAT FAILURE. THE ISSUE DESCRIBED ON THE TB IS IDENTICAL TO THE EXPERIENCE ISSUE. I CONTACTED MY MERCEDES DEALERSHIP SERVICE DEPARTMENT. THEY INFORMED ME THERE IS NO RECALL AND DON'T CONSIDER THIS ISSUE A SAFETY ISSUE. THEY WON'T REPLACE THE ELECTRICAL CABLE UNLESS I PAID FOR THE "SERVICE". THE CABLE HAS NOT BEEN DAMAGED OR DISCONNECTED. IT IS SIMPLY FAULTY AND MERCEDES KNOWS THE ISSUE AS THEY ISSUED A TB FOR THE VEHICLE.

EXCESSIVE BRAKE DUST WHEN DRIVEN EVEN A FEW MILES. FEEL INSECURE DRIVING IN TRAFFIC.

LOW PRESSURE FUEL LINE LEAK COULD CAUSE FIRE, FUEL SMELLS VERY STRONG IN THE CABIN I HAVE 2 2015S BOTH HAVE HAD THIS ISSUE ONE IS FROM CALIFORNIA SO IT NOT A SALT ISSUE. HAPPENS ON COLD START

HIGH FUMES OF GASOLINE AT START UP INSIDE CABIN AND OUTSIDE OF CABIN. SMELL IS USUALLY MORE PRESENT WHEN TANK IS FULL OR NEARLY EMPTY HOWEVER CAN BE PRESENT EVEN AT HALF A TANK. NO CODES APPEAR OR CHECK ENGINE LIGHT IS NOT TRIGGERED BY PROBLEM.

EXPLODING PANORAMIC ROOF. ON JANUARY 18, 2019, TWO HOURS INTO DRIVING FROM NEW YORK TO CANADA FOR A FAMILY VACATION, WITHOUT ANY WARNING AND FOR NO APPARENT REASON THE PANORAMIC ROOF TO OUR 2015 MERCEDES BENZ C300 4MATIC SUDDENLY AND VIOLENTLY EXPLODED. AT THE TIME OF THE OCCURRENCE THE HIGHWAY ROAD (I84E)WAS STRAIGHT, SMOOTH AND WE WERE AT CRUISING SPEED (60MPH), NO CARS ANYWHERE NEAR US IN FRONT OR FROM THE REAR. THE EXPLOSION SOUNDED AS IF A BOMB HAD GONE OFF OR IF WE HAD BEEN SHOT. TINY GLASS PARTICLES SPRAYED MY ENTIRE FAMILY INCLUDING MY WIFE, 2 DAUGHTER (12,15) AND OUR PUPPY. LUCKILY THE SUNSHADE COVERING UNDERNEATH THE GLASS ROOF CAUGHT THE LARGER PIECES OF BROKEN GLASS. AFTER MAKING SURE THE FAMILY WAS NOT INJURED I MANAGED TO FIND A LARGE PIECE OF CARDBOARD THAT I DUCT TAPE TO THE ROOF AND SLOWLY MADE OUR WAY BACK HOME, ENDING OUR TRIP. UPON ARRIVING HOME I DID LOTS OF RESEARCH AND TO MY SURPRISE FOUND THAT EXPLODING PANORAMIC ROOFS WAS MORE COMMON THAN I HAD EVER THOUGHT WITH MANY OWNERS GONE THROUGH THE EXACT SITUATION AS I. YET, MERCEDES REFUSES TO ACKNOWLEDGE THIS ISSUE AND PRESENTLY DOES NOT HAVE A RECALL ON THEIR PROBLEM. TO ADD INSULT TO INJURY WHEN I BROUGHT THE VEHICLE TO THE DEALERSHIP FOR A REPAIR, THE SERVICE ADVISOR ACTED AS IF THIS WAS NO BIG DEAL AND ALSO THAT HE HAS NEVER SEEN THIS ISSUE IN HIS 34 YEARS OF BEING THERE. I CAN ONLY ASSUME THAT THIS IS A FALSE STATEMENT SINCE THE VALLET PERSON WHO TOOK MY CAR SAID HE HAS SEEN IT ON QUITE A FEW OCCASION. MERCEDES BENZ OF NORTH AMERICA NEEDS TO ADDRESS THIS SITUATION BEFORE IT BECOMES A FATAL MISHAP. THE SOUND AND GLASS DEBRIS COULD HAVE EASILY DISTRACTED ME ENOUGH FOR ME TO LOSE CONTROL OF THE VEHICLE AND CAUSE AN ACCIDENT. LUCKILY NO ONE WAS NEAR OUR CAR.

PANORAMIC SUNROOF SPONTANEOUSLY EXPLODED WHILE THE CAR WAS SITTING. MERCEDES CLAIMING SOMETHING FELL INTO IT, BUT THERE WAS NOTHING ABOVE IT OR IN THE CAR WHILE IT WAS SITTING IN THE GARAGE. AFTER READING ONLINE, THIS IS HAPPENING TO A LOT OF OTHER CONSUMERS, INCLUDING ONE WHO HAS STARTED A CLASS ACTION LAWSUIT IN CALIFORNIA

MERCEDES BENZ WONT HONOR THE RECALLS. VEHICLE WAS IMPORTED (NOT BY ME) FROM CANADA. MERCEDES BENZ CONSIDERS THIS VEHICLE TO BE "GRAY MARKET VEHICLE" AND WONT SERVICE THE VEHICLE FOR RECALLS. THERE ARE UP TO EIGHT (8) SAFETY RECALLS AND THEY MAKE THE VEHICLE UNSAFE TO DRIVE. VEHICLE STILL UNDER FACTORY WARRANTY. I HAVE CONTACTED THE BUREAU OF AUTOMOTIVE REPAIR, WHO REFERRED ME TO THE NEW MOTOR VEHICLE BOARD WHO REFERRED ME TO THE NHTSA. THANK YOU FOR YOUR ATTENTION TO THIS MATTER,

OCCASIONALLY A BLUE SCREEN POPS UP FOR 1-2 SECONDS AND GOES TO THE INITIAL START UP SCREEN FOR A WHILE. I WENT TO MY LOCAL DEALERSHIP AND THE ADMITTED OF HEARING ABOUT THIS PROBLEM FROM OTHER OWNERS WITH THE SAME ISSUE AND SAID THERE WAS NOTHING THAT COULD BE DONE CAUSE THEY HAVE NO IDEA HOW TO FIX IT, I MEAN THAT'S ABSURD.

THERE IS A SERIOUS PROBLEM WITH THE VEHICLE MENTIONED ABOVE. THE ENTERTAINMENT SYSTEM AND THE REAR CAMERA DO NOT WORK. THIS IS A SERIOUS SAFETY CONCERN REGARDING THE REAR CAMERA. THE C-CLASS IS DESIGNED IN SUCH WAY THAT YOU DEPEND ON THE CAMERA WHEN REVERSING AND IT IS VERY DIFFICULT TO SEE THE REAR VIEW WHEN BACKING AND LOOKING FROM ALL ANGLES. I CALLED YOUR HQ IN MARYLAND FOR ASSISTANCE, THEY WERE UNAWARE OF POTENTIAL REPORTED PROBLEMS. THEIR BEST ANSWER WAS TO CALL THE DEALERSHIP. THE FOLLOWING DAY, I RECEIVED A PHONE CALL FROM NEW COUNTRY MOTOR CARS MERCEDES BENZ OF HARTFORD, CT STATING THAT THEY HAVE NOT HEARD OF THIS PROBLEM AND ITS VERY UNLIKELY THAT IT WAS ASSOCIATED WITH THE RECENT RECALL REGARDING THIS VEHICLE. UPON ARRIVAL, AND RETELLING MY STORY TO THE SERVICE ADVISOR HELDER CRESPO, HE TOLD ME THAT THEIR RECEIVED NUMEROUS COMPLAINTS ABOUT THIS PARTICULAR VEHICLE MAKE AND THAT OTHER CUSTOMERS ARE AFFECTED BY THIS SIMILAR PROBLEM. IT BEEN THREE WEEKS, I HAVE NOT HEARD ANYTHING FROM MB OR DEALERSHIP. I AM QUIET APPALLED BY THIS MATTER AND SHOCKED BY THE IMPROPER COMMUNICATION FROM MB TO THEIR LOYAL CUSTOMERS. IS THIS 'THE BEST OF NOTHING' CUSTOMER RELATION?! I AM EXTREMELY DISSATISFIED HOW THIS MATTER IS BEING HANDLED AND THAT NOT EVEN ONE SINGLE PERSON WHO KNEW ABOUT THIS ISSUE DID NOT EVEN APOLOGIZE FOR THE INCONVENIENCES THAT THIS HAD CASED ME.

MY NAVIGATION AND CENTRAL CONTROL PANEL NOT FUNCTIONING AND FREEZING WITH MESSAGE "PLEASE WAIT". CAUSED SO MANY SAFETY PROBLEMS, INCLUDING BACKUP CAMERA NOT WORKING, TEMPERATURE CONTROL AND AIRFLOW SCREEN NOT SHOWING UP, BLUETOOTH PHONE SYSTEM NOT WORKING TO TAKE HAND-FREE CALLS, AND NO RADIO STATION IS WORKING AND/OR ONLY ONE UNKNOWN RADIO STATION TUNEUP BUT CAN'T SWITCH TO ANOTHER STATION AT ALL TO LISTEN HIGHWAY TRAFFIC INFORMATION. IT'S BEEN ALREADY 3 WEEKS AND I VISITED DEALERSHIP AND CALLED MERCEDES BENZ CUSTOMER SERVICES BUT NO HELP/SOLUTION AVAILABLE SO FAR. ASKED ME TO JUST WAIT FEW MORE DAYS.

I HAVE A 2015 MERCEDES BENZ C300. I HAVE NOT EVEN OWNED THE CAR FOR ONE YEAR AND I HAVE ALREADY HAD A WHOLE LIST OF PROBLEMS THAT ARE NOT BEING RESOLVED. THE STEREO QUIT WORKING, THE BACK UP CAMERA DOESN'T WORK, THE AC WORKS ON AND OFF, AND MY HANDS FREE DOES NOT WORK AT ALL. THIS ALL HAPPENED ONE DAY WHEN I TURNED ON MY CAR TO LEAVE WORK. THE STEREO WAS FROZEN AND IT HAS STUCK LIKE THAT. MERCEDES HAS NOT SENT OUT A RECALL OR ANY NOTIFICATION AT ALL. I TOOK THE CAR TO THE DEALERSHIP AND THEY SENT IT BACK WITH NO IDEA OF WHEN IT WILL BE FIXED.

DONT KNOW WHICH CATEGORY IT FALLS. I BOUGHT THIS CAR IN AUGUST 2015. IN ONE WEEK IT WOULD NOT START EVEN. TOWED TO DEALERSHIP AND THEY SAID, THE GROUNDING SCREW WAS LOOSE. I AM SO SURPRISED THAT A CAR COMES OUT FROM FACTORY WITH A LOOSE GROUNDING ISSUE. IN THE LAST 2 WEEKS, THE CAR JUST STALLED AT THE SIGNAL. ALL LIGHTS CAME UP. I HAD THE ECO START/STOP MODE ON. THIS HAPPENED 3 TIMES AND FINALLY I SHUT THE ECO START/STOP MODE DOWN. IT IS SO DANGEROUS THAT IN HEAVY TRAFFIC, WHEN PEOPLE ARE READY TO DRIVE ON CHANGE OF SIGNAL, THE CAR WONT MOVE, PEOPLE ARE HONKING AND FRUSTRATED AND I AM TOO. LOOKED ONLINE AND SO MANY PEOPLE ARE COMPLAINING THE SAME. THE WHOLE OF DASHBOARD LIGHTS UP LIKE WHEN A CAR STALLS. THIS IS VERY DANGEROUS. ANYBODY WAITING BEHIND YOU CAN TAKE THE PEDAL FROM THE BRAKE AND SMASH INTO YOU. SIMILARLY, FOR LAST 2 MONTHS, I HAVE NOTICED THAT THERE IS A JUMPING NATURE WHEN YOU TAKE LEG OF THE BRAKE AT THE SIGNAL. THAT SCARES ME AS WELL. FROM THE FEEL OF IT, I FEEL THIS IS PRIMARILY A SOFTWARE ISSUE WHERE THE COMPUTER THINKS IT IS IN SOME MODE WHEN IT IS NOT OR SOMETHING AND SHUTS EVERYTHING DOWN AS A PRECAUTIONARY MEASURE OR SOMETHING

RADIO, BLUETOOTH TELEPHONY COMMAND CONTROL STOPPED WORKING (ERROR MESSAGE SAYS 'DEVICE UNAVAILABLE'); ON MAR 19 2018, MERCEDES BENZ DEALER (CHICAGO) REPRESENTATIVE SAID THE CAR NEEDS SOFTWARE UPDATE BUT COULD NOT SAY WHEN THE UPDATE WILL BE AVAILABLE. LACK OF HANDS-FREE TELEPHONY MAKES DRIVING UNSAFE.

COLLISION ASSIST INOPERATIVE DASH LIGHT CAME ON WHILE HIGHWAY DRIVING FOLLOWED BY A LOSS OF POWER AND ACCELERATION. VEHICLE NEEDED TO BE TURNED OFF AND RESTARTED TO BE DRIVABLE.

I WAS DRIVING AT APPROX. 20-25 MPH DURING DAY LIGHT AND ALL OF A SUDDEN THERE WAS LIGHT BLINKED ON MY DASHBOARD FOR APPLYING THE BRAKES BECAUSE OF ANOTHER VEHICLE AHEAD OF ME. I APPLIED THE BRAKES AS WELL AS BRAKE ASSIST PLUS SYSTEM GOT ACTIVATED AS WELL. BUT STILL MY VEHICLE END UP HITTING THE VEHICLE AHEAD OF ME. THE BRAKE ASSIST PLUS SYSTEM WHICH IS CLAIMED BY MERCEDEZ TO TAKE BRAKE AUTOMATICALLY TO BRING THE SYSTEM TO HALT IN CASE OF EMERGENCY DID NOT WORK AND IT END UP HITTING ANOTHER VEHICLE IN FRONT OF MY VEHICLE

TL* THE CONTACT OWNS A 2015 MERCEDES-BENZ C350. WHILE DRIVING 65 MPH, THE ACCELERATOR PEDAL WAS DEPRESSED, BUT THE VEHICLE FAILED TO ACCELERATE. MULTIPLE WARNING INDICATORS ILLUMINATED. AFTER THE VEHICLE WAS TURNED OFF AND RESTARTED, IT OPERATED CORRECTLY. THE VEHICLE WAS TAKEN TO FRED MARTIN OF YOUNGSTOWN (4701 MAHONING AVE, AUSTINTOWN, OH 44515, (330) 793-2444) WHERE THE CONTACT WAS UNAWARE OF THE DIAGNOSIS; HOWEVER, HE WAS INFORMED THAT SOME OF THE WIRING WAS CLEANED. THE CONTACT MENTIONED THAT THE FAILURE RECURRED A YEAR LATER AND AN APPOINTMENT WAS SCHEDULED WITH THE DEALER FOR DIAGNOSTIC TESTING. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND INFORMED THE DEALER TO CONTACT THEM WITH THE DIAGNOSTIC RESULTS. THE APPROXIMATE FAILURE MILEAGE WAS 17,000. THE VIN WAS NOT AVAILABLE.

THE VEHICLE'S COLLISION PREVENTION ASSISTANT PLUS OPTION OFTEN DISPLAYS DURING DRIVING. THIS CAUSES THE CAR TO LOSE ACCELERATION AND PREVENTS YOU FROM ACCELERATING REGARDLESS OF HOW HARD YOU PRESS THE GAS PEDAL. THIS HAPPENS FOR NO APPARENT REASON AND OCCURS WHILE IN THE MIDST OF DRIVING, USUALLY WITHIN A BUSY INTERSECTION AND HAS ALSO HAPPENED TO ME SEVERAL TIMES WHILE DRIVING ON THE HIGHWAY. I AM VERY AFRAID TO DRIVE THIS VEHICLE. THE ONLY WAY TO CORRECT THIS WHEN IT OCCURS IS TO PULL OFF THE ROAD, SHUT THE CAR DOWN, AND RESTART THE ENGINE AFTER A FEW MINUTES. MY CAR WAS SERVICED ON 1/13/18 AND WHEN TESTED, NO EVIDENCE OF THIS WAS FOUND. SINCE THEN, THIS MALFUNCTION HAPPENED ON 1/14 AND AGAIN TODAY 1/15. THIS MALFUNCTION HAS THE POTENTIAL TO BE CATASTROPHIC. I'VE ADVISED THE DEALER THIS NEEDS TO BE SERVICED AND FIXED, OTHERWISE WE WILL BE ASKING FOR A NEW VEHICLE FOR THE REMAINDER OF THE LEASE. I AM VERY FEARFUL TO DRIVE THE CAR, ESPECIALLY WITH OUR TWO YOUNG CHILDREN.

MY SUNROOF EXPLODED/SHATTERED WHILE I WAS DRIVING TODAY, TRAVELING AT A SPEED OF 45MPH ON CITY ROAD AFTER TURNING A CORNER. OUTSIDE TEMP WAS AROUND 85 AND INSIDE CAR WAS 75. CAR HAS AROUND 6800 MILES, AND THERE WAS NOTHING THAT HIT THE SUNROOF. SCARY SITUATION FOR THE DRIVER! CAR IS CURRENTLY UNDER WARRANTY AND AT THE DEALER FOR REPAIR, BUT THEY WANT MY INSURANCE TO PAY. I INSIST THIS BE INVESTIGATED BECAUSE I BELIEVE IT TO BE A MANUFACTURE DEFECT

TL* THE CONTACT OWNS A 2015 MERCEDES-BENZ C300. WHILE DRIVING 30 MPH, THE POWER STEERING SYSTEM FAILED. THE CONTACT PULLED THE VEHICLE OVER TO THE SIDE OF THE ROAD AND RESTARTED THE VEHICLE, BUT THE POWER STEERING ABILITY CONTINUED TO FAIL. THE VEHICLE WAS TOWED AND REPAIRED.

I WAS DRIVING 580-E AND MERGING ONTO I-5 S WHEN I HIT A HUMONGOUS POT HOLE WITH MY LEFT FONT TIRE CAUSING IT TO IMMEDIATELY BLOW OUT. THAT IN-TURN CAUSED MY STABILITY TRACKING TO ENGAGE, WHICH CAUSED ME TO SLOW DOWN DRASTICALLY. THAT CAUSED ANOTHER VEHICLE TO NEAR MISS RAMMING ME IN THE BACK AND ME SIDE SWIPING ANOTHER VEHICLE. I WAS DRIVING APPROXIMATELY 70 MPH AND ALMOST LOST CONTROL OF THE VEHICLE AND HAD TO IMMEDIATELY PULL OVER TO A VERY NARROW SHOULDER OF THE ROAD WITH MY EMERGENCY FLASHERS BLINKING. TO ENSURE THE SAFETY OF THE VEHICLE, MY SELF AND OTHER PASSENGERS IN THE CAR, I HAD TO DRIVE APPROXIMATELY 0.5 MILES TO THE NEXT EXIT (67) TO SAFELY GET MY VEHICLE OFF THE ROAD TO A SAFE LOCATION. I THEN CALLED A TOW TRUCK TO TOW MY VEHICLE BACK TO SANTA ROSA WHERE I LIVE TO GET THE TIRE REPLACED AND FRONT BUMP REPAIRED. I AM UNSURE OF THE CAUSE OF THE UNSAFE CONDITION OF THE HIGHWAY OR WHAT CAUSED THE POT HOLE. THERE WERE SEVERAL CARS STRANDED WITH DAMAGES TO THEIR VEHICLES AS WELL. ONE PERSON CAME TO THE SAME EXIT (FOOD MART ON PATTERSON ROAD) WITH A BLOWN OUT TIRE AS WELL. I HAVE HER CONTACT INFORMATION IF YOU NEED TO CONTACT HER.

NEW CAR PURCHASES IN 2015, FEWER THAN 25000 MILES. WHILE DRIVING LOCALLY, "COLLISION PREVENTION ASSIST" MALFUNCTION AND "CHECK ENGINE" LIGHTS LIT UP THE DASH BOARD. VEHICLE WOULD NOT PICK UP SPEED AND DRIVING WAS WEIRD. WAS ABLE TO DRIVE TO DEALERSHIP WHICH IS ABOUT 8 MILES AWAY. SITUATION COULD BE POTENTIALLY DANGEROUS IF HAPPENS ON A HIGHWAY AND IT WARRANTS ATTENTION. *TR

WHILE DRIVING, THE CAR LOSES THROTTLE AND THE ENGINE DOES NOT FUNCTION AT ALL. THE FOLLOWING ERROR SHOWS ON THE DASH: "INOPERATIVE SEE OPERATOR'S MANUAL". WHEN THIS HAPPENS, YOUR ONLY CHOICE IS TO COAST TO A SAFE PLACE. AFTER RESTARTING THE CAR, IT WILL FUNCTION FOR A SHORT TIME, ONLY TO REOCCUR. THIS OBVIOUSLY CAN BE DEADLY IF YOU CANNOT GET OFF THE HIGHWAY BEFORE THE CAR COMES TO A STOP. THIS HAS HAPPENED AT VARIOUS SPEEDS. *TR

WHILE ACCELERATING FROM A STOP LIGHT FROM 0 TO SLIGHTLY OVER 40 MPH RECEIVED ERROR CODE OF ANTI COLLISION ASSIST INOPERABLE AND THE VEHICLE WENT FROM 40 MPH TO 0 LIKE I HIT A TREE. IT WAS NOT A SLOW SMOOTH MOTION OF SLOWING TO A STOP. THIS WAS A VIOLENT STOP THROWING ME FORWARD AND CAUSED MY SEAT BELTS TO ACTIVATE. IT SHOULD BE NOTED THAT THERE WAS NOT A SINGLE PERSON IN FRONT OF ME, BEHIND ME OR BESIDE ME. THIS WAS NOTHING SHORT OF A MIRACLE BECAUSE IF ANYONE HAD BEEN BEHIND ME, I WOULD HAVE BEEN REAR ENDED AND IF ANYONE HAD BEEN IN THE RIGHT HAND LANE I WOULD HAVE HIT THEM AS THE VEHICLE PULLED TO THE RIGHT VERY HARD WHEN IT MALFUNCTIONED. I TOOK THE CAR TO THE DEALER AND TOLD THEM I DID NOT WANT THE CAR BACK UNLESS THEY COULD DETERMINE WHAT HAD HAPPENED AND COULD PROMISE THAT IT WOULD NEVER HAPPEN AGAIN. UPON READING SO MANY COMPLAINTS ABOUT THE SAME LIFE THREATENING ELECTRICAL MALFUNCTION, THERE IS NO POSSIBLE WAY THAT MERCEDES BENZ IS NOT FULLY AWARE OF THE POTENTIAL FOR SERIOUS INJURY OR DEATH. I HAVE CALLED MB USA AND WAS TOLD THAT I WOULD NEED TO FILE A CUSTOMER INQUIRY. DONE. I PURCHASED THE VEHICLE IN APRIL 2016 WITH 7,200 MILES ON IT. I AM COMPLETELY TERRIFIED TO DRIVE THE CAR.

WHILE I WAS DRIVING ON THE HIGHWAY & LOCAL ROADS, THE CAR SUDDENLY BECAME UNRESPONSIVE AND STARTED SHOWING MESSAGES THAT ALL SYSTEMS ARE INOPERATIVE. PRE SAFE FUNCTIONS LIMITED,AND INOPERATIVE TRACTION CONTROL LIGHT COMES ON ALONG WITH THE BLINDSPOT NOT ACTIVATED, ESP SYSTEM WAS OFF AS WELL. THE CAR STARTED SLOWING DOWN AND HAD TO BE PULLED OVER TO TURN OFF AND ON. THIS HAS HAPPENED 3-4 TIMES AND ON BUSY ROADS, CAR IS SENT TO THE SHOP AND ONLY HAS 27000 MILES. I AM SCARED TO DRIVE AS I COULD DIE IN A CAR ACCIDENT BECAUSE OF THIS [XXX] CAR. MERCEDES NEED TO RECALL THIS ASAP, IF THEY ARE NOT THEN WE SHOULD OPEN A CLASS ACTION LAWSUIT AGAINST THEM AS THEY ARE PLAYING WITH OUR LIVES. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

TL* THE CONTACT OWNS A 2015 MERCEDES-BENZ C300. WHEN THE VEHICLE WAS STARTED, THE COLLISION PREVENTION ASSIST PLUS INOPERATIVE WARNING INDICATOR ILLUMINATED.

THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 1,800.

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

TL* THE CONTACT OWNS A 2015 MERCEDES BENZ C300. THE CONTACT STATED THAT WHILE DRIVING AT 55 MPH, THE GLASS IN THE SUNROOF COLLAPSED WITHOUT IMPACT. THE VEHICLE WAS TAKEN TO THE DEALER WHERE THE SUNROOF WAS REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 21,000.

I HEARD A VERY BIG DEVASTATING NOISE WHILE DRIVING MY 2015 MERCEDES BENZ-C300 ON A LOCAL ROAD IN RALEIGH, NC AT ABOUT 40 MPH. SINCE I DID NOT SEE ANY TPMS (TIRE PRESSURE MONITORING SYSTEM) OR ANY OTHER KIND OF ALERT ON THE SCREEN, I CONTINUED TO DRIVE. AFTER DRIVING ABOUT 2 MORE MILES, I HEARD ANOTHER BIG POP AND THE CAR BECAME NON-DRIVABLE BY THEN. I DID NOT FEEL HITTING ANY OBJECT OR GOING THRU A POT HOLE. THAT'S WHEN I GOT DOWN THE CAR AND NOTICED THE RIGHT FRONT TIRE OUTER WALL GOT SEPARATED FROM THE TIRE AND THE THE TIRE WAS JUST FLAT TO THE GROUND. I COULD NOT, OF COURSE, DRIVE FURTHER. THIS HAPPENED ON SATURDAY (10/1/16) EVENING AND IT IS A RUN-FLAT TIRE, BUT COULD NOT DRIVE FURTHER AND THERE WAS NO SPARE IN THE CAR. SO, I HAD TO WAIT UNTIL TODAY (10/3/16) TO GET IT TOWED TO THE NEAREST BENZ DEALER IN RALEIGH TO GET THE TIRE REPLACED. IT WAS A VERY FRUSTRATING HALF A DAY ATTENDING TO THIS REPAIR. THERE ARE A COUPLE OF ISSUES HERE. (A) QUALITY ISSUE: WHY THE CONTINENTAL TIRE TIRE GAVE AWAY SO QUICKLY WITH ONLY ABOUT 23.5K MILES ON THE ODOMETER, WITHOUT HITTING ANY OBJECT? (B) SAFETY ISSUE: THIS WOULD HAVE BEEN A DISASTER IF I WERE ON A ROAD TRIP WITH FAMILY ON A NATIONAL HIGHWAY, ESPECIALLY, ON A SATURDAY EVENING WITHOUT A SPARE TIRE. (C). SYSTEM RESPONSE ISSUE: WHY MB SYSTEM DID NOT GIVE ANY KIND OF ALERT IN SPITE THIS MAJOR BLOW-OUT? I WOULD HESITATE TO BUY ANOTHER CAR WITHOUT A SPARE TIRE. I HOPE THE NHTSA WILL CONSIDER SERIOUSLY DISCOURAGING RUN-FLAT TIRES IN THE CARS UNLESS A SPARE TIRE IS PROVIDED, UNTIL SUCH TIME THE RUN-FLATS ARE EXTREMELY SAFE AND STURDY. THANKS.

IT HAPPENED TWO TIMES THE PAST 20 DAYS. CAR ENGINE STOPPED SUDDENLY WHILE DRIVING. FIRST TIME AT A SPEED OF ABOUT 20 MPH, SECOND TIME ON HIGHT WAY ABOUT 70 MPH. IT WAS EXTREMELY DANGEROUS THE SECOND TIME BECAUSE I WAS RIGHT AT THE PORT GETTING ONTO THE HIGH WAY AND I FOUND THE ENGINE WENT OFF. NO RESPONSE WHILE PUSHING THE ACCELERATOR PEDAL DOWN. I DID NOT HAVE TIME CHECK WHAT THE PROBLEM WAS BECAUSE TWO OTHER VEHICLES AT BACK ALMOST CRASH ON ME. I STOPPED THE VEHICLE ON THE SIDE OF THE HIGH WAY ENTRANCE IMMEDIATELY AND RESTARTED THE VEHICLE (I KNEW FROM LAST TIME IT WORKED BY DOING THIS) AND GOT BACK ON THE ROAD. THIS WAS A SERIOUS/FATAL PROBLEM. I SAW OTHERS COMPLAIN ABOUT THEIR MERCEDES-BENZ C SERIES HAVING SIMILAR ENGINE SHUTTING OFF ON THE ROAD PROBLEM, TOO. THERE WAS ONE PERSON ASKED ON YAHOO ANSWERS ABOUT THE SAME PROBLEM, HOWEVER HE DID NOT GET A RESPONSE FROM ANYONE. HTTPS://ANSWERS.YAHOO.COM/QUESTION/INDEX?QID=20151004200837AASQX6B I'M ALSO MAKING SOME SCREEN SHOTS OF PEOPLE WITH C300 FILED COMPLAINS ABOUT THE PROBLEM. THE MANUFACTURE NEED TO PAY ATTENTION TO THE PROBLEM.

COLLUSION PREVENTION SYSTEM INOPERATIVE. CAUSES CAR TO SLOW SLOW DOWN AND OR STOP WHILE ON THE ROAD. POSES A SEVERE LIFE THREATENING DRIVING CONDITION FOR ME AND OTHER DRIVERS. MANY OTHER MERCEDES BENZ OWNERS ACROSS THE USA, CANADA, AND JAPAN ARE COMPLAINING OF THE SAME ERROR MESSAGE AND ISSUES. MY MBUSA ADVISOR STATED HER VEHICLE IS DOING THE SAME THING. MY SERVICE ADVISOR AT THE DEALERSHIP STATED ITS MICE THAT ARE EATING THE WIRES. I AM TAKING MY VEHICLE TO TWO OTHER MECHANICS FOR OPINIONS ON THE CAUSE OF THE ERROR MESSAGE. I HAVE DOCUMENTS FROM OTHER MERCEDES BENZ OWNERS WHO HAVE COMPLAINED OF THE SAME ISSUE AND ERROR MESSAGE.

THE MANDATORY REQUIRED TIRE PRESSURE MOTORING SYSTEM (BECAUSE IT HAS RUN FLAT TIRES) ON ONE OF THE WHEELS FAILED AND THEY CLAIMED THIS IS NOT COVERED BY EITHER THE MANUFACTURER'S WARRANTY OR THE TIRE PROTECTION WARRANTEE. I WAS TOLD THIS ON 6/15 2015 BUT THE ORIGINAL COMPLAINT I MADE ABOUT AIR PRESSURE INT HE LEFT REAR TIRE WAS WELL WITHIN THE WARRANTEE PERIOD.

MULTIPLE INCIDENTS OF 'COLLISION PREVENTION ASSIST PLUS INOPERATIVE'. CAR LOSES ALL POWER UNTIL RESTARTED. THIS HAPPENED SEVERAL TIMES, ONCE ON AN INTERSTATE AT 65 MPH CREATING A DANGEROUS SITUATION. I HAD TO PULL OVER SEVERAL LANES ON THE INTERSTATE WITH NO POWER WHILE OTHER CARS HAD TO AVOID ME. I BROUGHT THE CAR INTO THE DEALER AND AFTER A WEEK OF REPAIRS, THE SAME FAULT HAS OCCURRED TWICE IN THE FIRST 24 HOURS AFTER RETURN OF VEHICLE. FAULT OCCURRED AT 60 MPH DURING A PASSING MANEUVER ON A 2 LANE ROAD. AGAIN, WE WERE PUT IN A VERY DANGEROUS SITUATION. THIS IS AN UNSAFE VEHICLE. ATTACHED IS A PICTURE OF THE DASHBOARD FAULT THAT I PHOTOGRAPHED AFTER THE CAR COASTED TO THE SIDE OF THE ROAD. THE CAR WOULD NOT MOVE UNTIL I TURNED IT OFF AND RESTARTED.

WAS DRIVING ON CITY STREET, AND THE COLLISION PREVENTION ASSIST DISABLED WARNING SIGN CAME ON AND I LOST POWER TO THE CAR. I'M TOLD THIS IS CALLED "LIMP MODE." I TRIED TO PICK UP SPEED BY PRESSING THROTTLE TO THE FLOOR, BUT GOT NO REACTION AT ALL. THEN SOME POWER CAME BACK, BUT NOT MUCH. EACH TIME I BRAKED TO STOP FOR LIGHT OR TURN THIS WOULD HAPPEN. AFTER I GOT HOME I RESTARTED THE ENGINE AND IT SEEMED NORMAL AGAIN. HOWEVER I WAS AFRAID TO DRIVE IT, ESPECIALLY SINCE IN THE LAST SIX MONTHS MY POWER STEERING ALSO FAILED, AND HAD IT TOWED TO DEALER. THEY RAN TESTS AND NO CODE FOR FAILURE WAS FOUND. THEY SAID THEY FOUND SOME SOFTWARE UPDATES WHICH THEY DID. UNFORTUNATELY, AFTER I PICKED UP THE CAR FROM SERVICE I SAW THAT MY MAIN COMPLAINT WASN'T EVEN MENTIONED. ONLY THAT I SOMETIMES HAD PROBLEM WITH COLLISION CONTROL WARNING GOING OFF FOR NO APPARENT REASON.

WHILE DRIVING "COLLISION PREVENTION ASSIST PLUS INOPERATIVE" MESSAGE APPEARS ON DASHBOARD. CAR LOSES ITS ABILITY TO ACCELERATE. OCCURRED TWICE (JANUARY 2015) ON CITY STREETS FORCING ME TO PULL OVER TO THE SIDE OF THE ROAD AND RESTART MY CAR, THE ERROR DISAPPEARS AND I AM ABLE TO DRIVE NORMALLY. 4/7/16 OCCURRED WHILE TRAVELING 65MPH ON AN INTERSTATE. I LOST ABILITY TO ACCELERATE AND WAS ALMOST REAR-ENDED BY A SEMI-TRUCK. THE VEHICLE WAS SERVICED AT A MERCEDES DEALERSHIP ON 1/11/16 THE HIGHWAY INCIDENT OCCURRED AFTER THE "FIX". IT IS CURRENTLY BACK AT THE DEALERSHIP BEING TESTED BY THE SERVICE DEPARTMENT. I AM TOLD THE CURRENT FIX IS TO REPLACE ALL THE SENORS. I HAVE OPENED A CASE WITH MBUSA TO REPURCHASE THE VEHICLE GIVEN THE INITIAL REPAIR DID NOT WORK AND PUT ME IN PERILOUS HIGHWAY SITUATION. I PURCHASED THE VEHICLE IN OCTOBER OF 2015.

TL* THE CONTACT OWNS A 2015 MERCEDES-BENZ C300. WHILE DRIVING AT VARIOUS SPEEDS, THE VEHICLE WOULD INDEPENDENTLY DECELERATE WITH THE RPM GAUGE READING BETWEEN 4,000-5,000. THE FAILURE OCCURRED INTERMITTENTLY. WHEN THE VEHICLE WAS SHUT OFF AND RESTARTED, THE VEHICLE RETURNED TO NORMAL. THE VEHICLE WAS TAKEN TO THE DEALER FOR DIAGNOSTIC TESTING; HOWEVER, THE FAILURE COULD NOT BE DUPLICATED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 1,000.

TWO ISSUES, PURCHASED A CERTIFIED PRE OWNED VEHICLE. AT 8900 MILES, WE NOTICED THE CAR WAS IDLING VERY ROUGH ON A COLD START, ALMOST THE SOUND OF A DIESEL. THE SOUND WOULD RESOLVE AFTER 10 MINUTES OF DRIVING. SERVICE INFORMED US THAT THERE WAS A RECALL ON THE RODS AND PISTONS. WE HAD THE ENGINE REBUILT, AND THE NOISE IS THE SAME, IF NOT WORSE. THE CAR SOUNDS NOTHING LIKE LATERBUILD '15 MODELS OR '16 MODELS, NOR DOES IT RUN AS SMOOTHLY. SECONDLY, 5 OCCURRENCES INVOLVED INOPERATIVE COLLISION PREVENTION ASSIST WARNINGS AND INOPERATIVE ANTI-SKID WARNINGS APPEARING ON THE DASH CAUSING THE CAR TO REDUCE OPERATING SPEED TO 20MPH MAX. CAR NEEDED TO BE SHUT OFF AND RESTARTED AFTER A 5 MINUTE PERIOD EACH TIME THESE WARNINGS APPEARED, IN ORDER TO DRIVE OVER 20MPH. THE VEHICLE WAS SERVICED FOR THESE WARNINGS TWICE. THE FIRST SERVICE DIAGNOSED THE CAR WITH A CODING ISSUE. THE SECOND, INVOLVED REPLACING MODULES. THIS ALL OCCURRED DURING THE TWO MONTHS OF OWNING THE CAR. WE NOTICES SEVERAL SIMILAR COMPLAINTS REGARDING THE EARLY BUILD 2015 C300S, AND DECIDED TO CUT OUR LOSSES AND PURCHASE ANOTHER VEHICLE. WE DID NOT FEEL SAFE IN THAT CAR.

COLLISION PREVENTION ASSISTANCE FEATURE WENT ON AUTOMATICALLY ( AS WELL AS CHECK-ENGINE LIGHT) WHILE DRIVING AT HIGHWAY SPEED IN NORMAL WEATHER. I WAS NOT IN AN ACCIDENT, NEAR ANOTHER VEHICLE AND COMPLETELY AWARE AND DRIVING NORMALLY PRIOR TO THIS OCCURRING. I HAD TO STRUGGLE WITH CAR TO PULL OVER TO SHOULDER, LOSS POWER FROM GAS PEDAL, CAR HARD TO CONTROL. I HAD TO TURN OFF THE CAR, DEACTIVATE THE FUNCTION TO DRIVE. IT HAPPENED AGAIN WHEN I DROVE THE CAR LATER THAT DAY AFTER THE CAR HAD BEEN PARKED FOR A WHILE. TOOK IT INTO SERVICE. THEY WERE ABLE TO FIND THE ERROR CODE.THEY FOUND THAT MERCEDES SENT OUT A MEMO IN SEPT. 2015 STATING THEY ARE AWARE OF THE PROBLEM BUT SERVICE IS NOT TO DO ANYTHING TO "FIX" IT! I HAVE ONLY OWNED THIS CAR FOR 6 WEEKS ,BOUGHT IT NEW AND HAVE LESS THAN 6,000 MILES ON IT. MERCEDES IS NOT OFFERING A SOLUTION BUT MORE OF A WAIT AND SEE ATTITUDE.

WHILE DRIVING THE VEHICLE ON THE HIGHWAY AT 70 MPH, THE CRUISE CONTROL SHUT OFF AND THE CAR BEGAN TO SLOW DOWN. I WAS ABLE TO MAINTAIN CONTROL AND NOTICED 3 ERROR MESSAGES INCLUDING: ESC INOPERABLE, CRUISE CONTROL INOPERABLE, AND COLLISION PREVENTION PLUS INOPERABLE. I WAS ABLE TO CONTINUE DRIVING AND WHEN I WENT TO ACCELERATE FROM A STOP LIGHT, THE ACCELERATOR WAS UNRESPONSIVE AND TOOK SEVERAL SECONDS FOR THE VEHICLE TO MOVE ALMOST CAUSING AN ACCIDENT FROM A CAR TRAVELING CLOSE BEHIND ME. ALL OF THIS HAPPENED WHILE I WAS DRIVING THE VEHICLE TO THE DEALERSHIP FOR ITS FIRST SERVICE. THE DEALER WAS NOTIFIED OF THE PROBLEM AND IS INVESTIGATING THE ISSUE.

LOUD ENGINE KNOCKING WHEN ENGINE IS COLD. DIAGNOSED AS INCORRECT/UNFAVORABLE TOLERANCES OF PISTON WRIST PINS THAT WILL ULTIMATELY LEAD TO ENGINE FAILURE. DIAGNOSIS HAPPENED WITH ODOMETER AT 2,438 MILES.

WHILE DRIVING ON THE HIGHWAY IN THE PASSING LANE, A WARNING MESSAGE INDICATED THE ACCIDENT AVOIDANCE SYSTEM WAS MALFUNCTIONING. THIS DEACTIVATED THE ACCELERATOR, I HAD NO CONTROL OF THE CAR, SQUEEZED BETWEEN CARS AND COASTED TO A STOP. TURNED OFF CAR AND CALLED MERCEDES. CAR WAS RESTARTED WITH NO ISSUES INDICATED, DROVE THE CAR HOME. NEXT DAY ON THE HIGHWAY DID IT AGAIN, WENT DIRECTLY TO DEALERSHIP. THEY HAD THE CAR 4 DAYS, SAID IT WAS A COMPUTER CODE ISSUE AND WAS FIXED. LESS THAN A MONTH LATER IT DID IT AGAIN DRIVING 25MPH IN MY NEIGHBORHOOD. CALLED MERCEDES, THEY ARE PICKING THE CAR UP. I NO LONGER TRUST THE CAR, WILL NOT LET FAMILY DRIVE IT BECAUSE IT BECOMES DISABLED....

THE PANORAMIC SUNROOF IN MY CAR EXPLODED AT APPROXIMATELY 6.45AM ON MONDAY, JUNE 29TH 2015. THE CAR WAS PURCHASED NEW FROM MERCEDES BENZ IN PARAMUS ON SATURDAY, JUNE 27TH, 2015. THE CAR HAD 146 MILES ON THE ODOMETER. I WAS IN NJ AND I WAS TRAVELING WEST ON I-78 (EXPRESS LANES) AT APPROXIMATELY 65MPH. THERE WERE NO OTHER VEHICLES IN CLOSE PROXIMITY, THERE WAS A VEHICLE TRAILING A FEW CAR LENGTHS BEHIND ME. THE ROAD WAS RELATIVELY SMOOTH AND THE WEATHER WAS DRY. NO PROJECTILE HIT THE GLASS PRIOR TO IT EXPLODING. WHEN THE SUNROOF EXPLODED, ALL I HEARD WAS A LARGE BANG AND THEN GLASS FALLING INTO THE CAR AND ALSO 'EXITING' THE CAR. THE GLASS DEBRIS LEFT SIGNIFICANT PITTING ON THE TRUNK OF THE CAR. I ESTIMATE 25% OF THE GLASS CAME INTO THE CAR. I SWERVED INTO TO THE EMERGENCY LANE AND STOPPED IN THE EMERGENCY LANE.

I HAD TWO ISSUES WITHIN 2 MONTHS OF BUYING THE CAR EARLIER IN THIS. I PURCHASED THE CAR IN EARLY FEB 2015. I HEARD A LOUD SOUND IN THE HEATING UNIT, THEN A SMALL CLICKING SOUND ENSUED FOR OVER A WEEK. BROUGHT IT IN, THE MOTOR HAD BLOWN, SO THEY REPLACED IT WITHOUT A DIME OUT OF MY POCKET. THEN IN MARCH, I WAS DRIVING ABOUT 35 MILES PER HOUR WHEN A VERY LOUD NOISE LIKE BAD BREAKS STARTED AND WOULDN'T STOP NO MATTER WHAT I DID. WE TOWED IT USING MERCEDES, BUT HAD TO PAY FOR AN UBER TO THE DEALERSHIP. IT WAS AGAIN ANOTHER MALFUNCTION WITH THE NEW MODEL, AND THEY FIXED THE BREAKS AND ROTORS THAT SAME DAY WITHOUT A DIME OUT OF MY POCKET. I NOW HAVE 6500 MILES ON IT SINCE I GOT IT IN FEB THIS YEAR, AND THE CHECK ENGINE LIGHT CAME ON. I TRIED TO REPLACE THE FUEL CAP BUT THAT DIDN'T MAKE IT GO AWAY AND THE CAR IS DRIVING FINE. IM BRINGING IT IN LATER THIS WEEK. I SAW REPORTS THAT THERE ARE SOME CARS WITH THIS FUEL ISSUE THATS CAUSING THIS INDICATOR. OVERALL THIS ONE PARTICULAR CAR I LEASED IS A TOTAL DUD, BUT I HOPE THESE REPORTS HELP OTHERS WITH SIMILAR ISSUES.

I SAT IN THE CAR, HAD NOT STARTED IT YET, AND A "POWER STEERING MALFUNCTION, SEE OPERATORS MANUAL" WARNING IN RED WAS ON DASHBOARD SCREEN, AND ANOTHER SMALLER RED INDICATOR LIGHT OF A STEERING WHEEL WAS ON IN THE SPEEDOMETER AREA. STARTED THE CAR AND THE WARNINGS REMAINED. SHUT IT OFF AND IMMEDIATELY RESTARTED AND THE WARNINGS REMAINED. STARTING DRIVING THE CAR AND THE POWER STEERING WAS INDEED OUT. I HAD GREAT DIFFICULTY TRYING TO STEER, ESPECIALLY UNDER 5MPH. DROVE ABOUT A MILE AND THEN PARKED AND SHUT THE CAR OFF. CAME BACK ABOUT 10 MINUTES LATER, RESTARTED THE CAR AND THE WARNINGS WERE GONE AND STEERING WAS BACK TO NORMAL.

UNABLE TO MOVE DRIVER'S POWER SEAT FORWARD INTO SAFE OPERATING POSITION. HAD TO DRIVE CAR BY SITTING ON FRONT EDGE OF THE SEAT. BROUGHT TO DEALER FOR SERVICE AND SEAT OPERATION WAS RESTORED TO NORMAL AFTER A SOFTWARE RESTORE/RESET. SERVICE CONSULTANT COULD PROVIDE NO DEFINITE INFORMATION AS TO WHAT IS THE CAUSE OF THE PROBLEM. THE NEXT DAY IN THE MORNING, THE PROBLEM REOCCURED. I AM CONCERNED THAT THIS IS A CHRONIC PROBLEM THAT CANNOT BE REPAIRED. IT IS A BRAND NEW VEHICLE AND I DON'T KNOW IF THIS IS SOMETHING THAT AFFECTS OTHER VEHICLES.

I WAS DRIVING ON A RURAL BACK ROAD AT 30 MILES, THE POWER STEERING STOPPED WORKING. A WARNING APPEARED SAYING "MALFUNCTION OF POWER STEERING". I WAS ABLE TO DRIVE HOME, ABOUT ONE MILE, BUT WITH GREAT DIFFICULTY. I CALLED MERCEDES BENZ. THEY SENT A TOW TRUCK AND TOWED AUTO TO WESTWOOD MERCEDES IN WESTWOOD, MA. I WAS INFORMED IT WAS A SOFTWARE PROBLEM AND IT HAD BEEN REPROGRAMMED.

MY VEHICLE, A 2015 MERCEDES-BENZ C300 PURCHASED ON 6/6/15 WITH APPROXIMATELY 1200 MILES ON THE ODOMETER. ON MONDAY MORNING 7/20/15, AT APPROXIMATELY 5:30 AM PDT, I WAS DRIVING ON THE FREEWAY WHEN THE INTERIOR LIGHTS CAME ON AND THE DRIVERS DOOR POPPED OPEN. THERE WAS NO WARNING CHIME OR INDICATOR LIGHT PRIOR TO THIS HAPPENING. IT WAS VERY FRIGHTENING, AND CAUGHT ME BY SURPRISE. LUCKILY AT THE TIME THERE WERE NO OTHER CARS NEAR ME. I WAS ABLE TO SLOW DOWN AND SHUT THE DOOR. I CALLED THE DEALER AND THEY WERE CONCERNED AND HAD ME DROP IT OFF THAT AFTERNOON. PICKED UP ON TUESDAY AFTERNOON 7/21/15 APPROXIMATELY 5:30 PM PDT. I WAS TOLD THEY COULDN'T DUPLICATE THE DOOR OPENING. HOWEVER, LOOKING AT FORUMS ON THE INTERNET, THIS EXACT ISSUE HAS BEEN REPORTED BY OTHERS IN THE US AND AUSTRALIA AT LEAST. SOME WERE THE DRIVERS DOOR OTHERS WERE THE PASSENGERS DOOR. ONE REPORTED IT HAPPENING A SECOND TIME AFTER THE DEALER INSPECTED. I AM VERY CONCERNED ABOUT THIS HAPPENING AGAIN, AND POSSIBLY TRIGGERING AN AIR BAG OR AUTO-PARK. I DO NOT FEEL SAFE IN THIS CAR. I HAVE CONTACTED MERCEDES-BENZ USA VIA CHAT THIS MORNING 7/22/15 AND THEY WILL HAVE A CASE MANAGER CONTACT ME.

THE STEERING MALFUNCTION LIGHT CAME ON AND THE STEERING WHEEL LOST POWER. THE STEERING WHEEL LOCKED UP WHERE IT BECOME EXTREMELY DIFFICULT FOR ME TO MANEUVER THE CAR. I PUT ON MY EMERGENCY INDICATOR AND GOT THE CAR INTO A PARKING LOT AS SAFETY AS I COULD. HAD THIS OCCURRED WHILE I WAS GOING ON A ROAD WITH CURVES OR AT HIGH SPEED, I BELIEVE I COULD HAVE SUFFERED SEVERE BODILY INJURY. I CALLED MBRACE TO GET MY CAR TOWED. WHEN I TURNED MY CAR BACK ON AFTER APPROXIMATELY 5 MINS, THE ERROR WAS GONE AND IT WAS CLOSE TO 7PM AND THE SERVICE CENTER FOR THE DEALERSHIP WHERE I PURCHASED THIS CAR FROM WAS CLOSED. I DROPPED OFF THE CAR AT THE DEALERSHIP THE NEXT MORNING. TODAY IS THE SECOND DAY AND MY DEALERSHIP TELLS ME THAT THEY OPENED A CASE WITH MERCEDES AS THEIR WAS A FAULTY CODE IN THE STEERING ELECTRICAL BOX AND THEY WERE ADVISED BY MERCEDES TO SIMPLY RESET THE BOX AND DRIVE THE CAR FOR SOME TIME. HOWEVER THEY COULD NOT TELL ME WHY IT HAPPENED AND WHETHER THE RESET WILL PREVENT THE OCCURRENCE OF THE STEERING WHEEL MALFUNCTION AGAIN. I REFUSED TO TAKE A CAR BACK UNTIL ITS SAFETY IS PROVEN. THE DEALERSHIP IS KEEPING THE CAR UNTIL THEY HEAR FROM MERCEDES WHICH ACCORDING TO THEM COULD TAKE A FEW DAYS TO A WEEK+. I PURCHASED THIS CAR APPROXIMATELY 3 WEEKS AGO AND TO HAVE A MAJOR ISSUE WITH MY CAR WITH AND THE DEALERSHIP AND MERCEDES TO PROVIDE NO CONFIDENCE IN THE SAFETY OF THIS VEHICLE IS EXTREMELY APPALLING. ......UPDATED 12/17/15 *BF *TR UPDATED 10/11/2017*CN

ON 11/1/14 I FILED A COMPLAINT ABOUT SAFETY ISSUES WITH MY NEW 2015 MERCEDES, C300 (ODI # 10664470) THAT PERTAINED TO DEBRIS ENTERING THE ENGINE COMPARTMENT FROM THE TOP, NEAR THE WINDSHIELD, AND OTHER ISSUES WITH THE COMMAND "RADIO", "TOUCH PAD" & KEYLESS ENTRY LOCKING SYSTEMS. I UNDERSTAND THESE SYSTEMS ARE NOT PROPRIETARY TO MERCEDES AND SO ARE IN MANY OTHER LUXURY MODELS. I'VE REC'D NO FEEDBACK FROM THE DAIMLER CORP OR FROM YOUR OFFICE. NOW A NEW ISSUE DEVELOPED WHERE THE KEYLESS GO WOULDN'T ALLOW ME TO EITHER ENTER THE VEHICLE OR SOUND THE "PANIC" ALARM. THE COMPANY DOESN'T KNOW HOW OR WHY THIS COULD HAPPEN OR HOW TO FIX IT. I'M ESPECIALLY CONCERNED WITH THE INABILITY TO USE THE PANIC BUTTON, WHICH IS THERE IN CASE OF A CRIMINAL OR MEDICAL EMERGENCY. WHAT A SURPRISE WHEN YOU GO FOR IT AND IT DOESN'T WORK. THERE IS NO BACK UP SHOULD THE BATTERY FAIL TO WORK. I BELIEVE THIS IS ANOTHER SAFETY ISSUE WITH THIS CAR AND WOULD APPRECIATE IT IF YOUR OFFICE WOULD TAKE ME SERIOUSLY AND CONTACT ME BEFORE SOMEONE IS INJURED OR KILLED.. THANK YOU.. *TR

I STARTED THE ENGINE AND THE POWER STEERING FAILURE WARNING CAME ON. TRUE ENOUGH, IT WAS A STRUGGLE TO STEER MY CAR BACK HOME - I WAS JUST 3 MINUTES AWAY FROM HOME. THE CAR WAS TOWED THE NEXT MORNING TO AUTOHAUS ON EDENS IN NORTHBROOK, IL. I DID A GOOGLE SEARCH AND FOUND OUT THAT THERE HAS BEEN A RECALL FOR THIS EXACT PROBLEM IN EUROPE SINCE DEC 2014. I WAS SHOCKED THAT OWNERS IN THE US WERE NOT WARNED OF THIS POTENTIAL PROBLEM AND THERE HAS BEEN NO RECALL ISSUED. IF THIS HAD HAPPENED ON THE FREEWAY, IT LIKELY WOULD HAVE RESULTED IN A VERY SERIOUS ACCIDENT AND MY SAFETY COULD HAVE BEEN JEOPARDIZED. I WOULD LIKE OTHER OWNERS OF THE 2015 MERCEDES BENZ C CLASS TO BE ALERTED TO THIS POTENTIALLY SERIOUS MECHANICAL PROBLEM AND THE NHSTA TO INVESTIGATE WHY THERE HAS BEEN NO RECALL ISSUED IN THE US......UPDATED 12/17/15 *BF BOTH AXLES FRONT AXLES HAD TO REPLACED.

SOON AFTER PURCHASING MERCEDES, DISCOVERED THE FOLLOWING POTENTIALLY HAZARDOUS SAFETY ISSUES (ALL OF THESE FEATURES ARE STANDARD): 1) NEW "KEYLESS-GO LOCKING SYSTEM IS FACTORY PROGRAMMED TO UNLOCK ALL DOORS WHEN KEY IS IN OWNER'S POSSESSION & REAR DRIVER'S DOOR HANDLE IS TOUCHED, ALLOWING INTRUDER(S) TO EASILY ENTER OTHER SIDE OF VEHICLE. 2) NEW COMMAND/COMPUTER/TOUCH PAD SYSTEM, CONTROLS VARIOUS OPERATIONAL FUNCTIONS, LIKE RADIO, ENCOURAGING DRIVER TO TAKE EYES OFF THE ROAD TO OPERATE. TOUCHPAD REQUIRES DRIVER TO MAKE "MOUSE-LIKE" ACTIONS ON COMPUTER PAD (LOCATED ON CONSOLE) WHILE SIMULTANEOUSLY DRIVING. 3) NEW AIR FLOW & VENT SYSTEM, CIRCULATES AIR FROM GRILL TO WINDSHIELD, ALLOWING LEAVES & OTHER DEBRIS, INCL. WATER, TO ENTER ENGINE COMPARTMENT AT THE TOP OF HOOD. DEBRIS LODGED HERE COULD POTENTIALLY RESULT IN OVERHEATING & CAUSE FIRE OR RESULT IN DAMAGE TO WIRING AND/OR OTHER COMPONENTS OF THE ENGINE. 4) LETTERS (W/PICTURES) SENT TO MBUSA, CEO, RESULTED IN PHONE CALLS FROM SUBORDINATE STAFF, REJECTING OUTRIGHT EACH COMPLAINT BUT ADVISING THAT DEBRIS IN ENGINE AREA IS "NORMAL" & CUSTOMER'S RESPONSIBILITY TO REMOVE. LETTER TO DAIMLER'S CEO IN GERMANY WAS REFERRED BACK TO MBUSA. 5) ASKING FOR YOUR INTERVENTION BEFORE THESE PROBLEMS POTENTIALLY RESULT IN INJURY OR FATALITY. IF THIS IS NOT THE OFFICE TO INVESTIGATE & INTERVENE, PLEASE FORWARD TO THE CORRECT AGENCY & ADVISE ACCORDINGLY. CAN PROVIDE ADDITIONAL INFO. ON REQUEST. THANK YOU... *TR
