Engine blew at less than 80,000 miles

My engine starting making a knocking/ticking noise out of no where. I was traveling alone on the highway so I stopped to check it. I got to a gas station and google searched it and it came up that the LS 6.2 engine that is in my vehicle was recalled on other models because of this issue. I did have a mechanic look at it as well and he agreed it is that same issue that was recalled in other models.

The 2017 GMC Yukon has serious transmission issues that GM continues to ignore, and it is going to get someone hurt. I was stopped at a red light, and when it turned green, I pressed the gas pedal but the car would not move. I pressed harder, and then it suddenly lurched forward about 30 feet. If there had been a car in front of me, I would have hit them and likely caused injuries. When I took it to the dealership, they said it needed a full transmission replacement, which was not covered. I had to pay out of pocket. I was only about $10,000 outside the warranty when it failed, and GM refused to stand behind their product or help in any way. I was already financing the vehicle and should not have had to pay for a new transmission on a car that was less than four years old with relatively low miles. This is not just my experience. Many others have had the same issue. GM knows about it and chooses not to acknowledge it. They are lucky no one has been seriously injured or killed because of it. Going to attach all of the proof of people "coincidentally" experiencing the same issue.

The 8-speed automatic transmission (Hydra-Matic 8L90) on this 2017 GMC Yukon SLT 5.3L V8 has failed. This is a repeat failure — the transmission was previously rebuilt in 2020 under a GM recall/service action for the same known defect affecting this transmission type. The transmission has now failed again in 2026, approximately six years after GM's prior repair. Prior to failure, the vehicle exhibited hard shifting, shuddering during acceleration, and hesitation between gear changes — symptoms consistent with the known defect pattern documented across 2015–2019 GM vehicles equipped with this transmission. The failure was confirmed by a service center. The vehicle is currently not safely drivable. Safety concern: erratic and unpredictable gear changes, including sudden lurching and hesitation during acceleration, create a dangerous condition for the driver, passengers, and other vehicles on the road. GM has been contacted through their Customer Assistance Center (case opened). GM's initial position was that they cannot assist because the vehicle is out of warranty. However, this is a repeat failure of a previously repaired known defect. GM issued 13+ technical service bulletins on this transmission and has been aware of the root defect since at least 2018. A federal class action (Speerly v. General Motors, E.D. Michigan) covering this exact vehicle type and transmission has been certified and upheld by the Sixth Circuit Court of Appeals. The prior GM repair did not remediate the underlying defect.

Slipping Gears: Many Yukon Denali owners report experiencing unexpected gear changes or loss of power while driving. Hard Shifting: This problem manifests as harsh or abrupt gear changes, often accompanied by noticeable jolts when shifting from one gear to another. Unusual Noises: Grinding, whining, or clunking sounds when shifting There has been a class action lawsuit for this. I'm not sure why it has not been recalled in all states.

My truck lost power while I was driving. Took to a shop and they found that a had a bad lifter. I have all of my service records from the GMC dealership where I had my vehicle serviced on a regular basis.

This has been going on for a while now, but it’s getting worse overtime. If I push on my brakes more than twice the brake pedal locks up and I have to push extremely hard to get my vehicle stopped.. luckily I have never been going fast and had to worry about this. This is normally when I am pulling into a parking spot or I am backing up that I have to tap on my brakes a few times. A couple of times I have bumped the pole in front of my parking spot due to not having brakes. I just put in a general date as to when they started to get worse.

I started noticing issues with my transmission around 55,000 miles on it. It first started with no noticing that it wouldn’t gear down when it needed to, and then when it finally did gear down, it would really jerk the vehicle. I started calling GMC then and questioning and putting in a claim. Just went back-and-forth four months. Now it was getting worse to where I could feel the transmission slipping it wouldn’t kick into upper gear or lower gear. Again, I was still calling GMC and reporting these issues. I was told to take it and have a transmission oil change, which I did costing me $300. I still noticed this problem and I continue to call. I kept being told that they would have somebody call me back which nobody ever called me back to find out specifics. I took it to a GMC garage have them put it on a machine, and I was told that it needed a new transmission and this wasn’t something GMC was covering. This new transmission cost me $6200 and was done on 1/5/25. Please remember this vehicle only had 64,000 miles on it, which is absolutely ridiculous to need a transmission at this mileage. I again had called in January 2025 reporting this and was told someone would call me back and never heard from them.

Sitting at stop light engine began running rough and smoke coming out. CEL came on and began flashing, pulled over and had it towed. Diagnosis was PO300 misfire, dead miss on cylcinder 4, cylinder plug 4 is fuel fouled, cois is fine has good spark- caused by failed lifters. Needs engine replacement. Vehicle always serviced, garage kept and in mint condition with 89K miles.

The contact owns a 2017 GMC Yukon. The contact stated that the lifters were previously replaced in 2021 at the manufacturer's expense. Additionally, the contact stated that while driving at various speeds, the engine was running rough. The vehicle was taken to an unknown auto part store, where it was diagnosed with an engine cylinder malfunction. The vehicle was taken to an independent mechanic, where it was determined that the engine had experienced lifter failure or a more severe failure. The vehicle was not repaired. The manufacturer was notified of the failure and informed the contact that the vehicle needed to be diagnosed by the dealer, and that the manufacturer might help in covering the cost of the repair. The contact related the failure to NHTSA Action Number: EA25007 (Engine, Engine and Engine Cooling). The failure mileage was approximately 81,638.

At parking lot speeds, there have been many incedents of brake failure, when pressing pedal to stop pedal pulsates and becomes very hard to stop the yukon. there seems to be a vacume or booster issue. Yukon will be fine for days then reaccure when slowing at stop sign or waitng at red light and moving foward in slow traffic to sign or llight and then in happens again. scary and unreliable when using brakes at low speed intersections or continous stop and go's

We noticed the passenger side taillight was out. It’s not a simple bulb replacement but an entire assembly. It was put back in place and it lit up again. A few weeks later it wasn’t working. Pounded and tapped on it and it works again. We're guessing there is some sort of short so we asked for an estimate on getting an assembly replacement when it was in for a regular oil change. Shocked that a necessary part would cost $1,112.77!!! Whatever happened to changing a bulb for a few dollars?

The contact own a 2017 GMC Yukon. The contact stated that the vehicle failed to shift from 2nd to 3rd gear while driving and remained stuck in gear. There was no warning light illuminated. The vehicle was taken to the dealer, where it was diagnosed and determined that the transmission needed to be replaced. The vehicle was not repaired due to the cost. The manufacturer was notified of the failure and informed the contact that assistance would not be provided because the warranty had expired. The failure mileage was approximately 78,000.

WHEN I BOUGHT THE YUKON 3 YEARS AGO THE TRANMISSION WENT OUT WITHIN MONTHS, THEY REPLACED IT WITH A USED ONE, NOW IT IS STARTED TO DO THE SAME THING, IT WILL SLIP IN AND OUT OF GEAR, WHEN YOU GIVE IT GAS IT WILL JUMP INTO GEAR AT AN IDLE IT WILL DROP OUT OF GEAR, IT'S BEEN DOING THIS EVERY SINCE THEY PUT THE USED ONE IN, I NOITIED THEM THEY SAID THAT IT IS NORMAL???? I HAD THE WORK DONE @ PAHRUMP VALLEY AUTO PLAZA. I'M AFRAID THAT WHEN IM AT A LIGHT IT WILL NOT GO INTO GEAR AND I WILL GET HIT. NO WARING LAMPS CAME ON AT ALL, IT HAS PROGRESSIVELY GOTTEN WORSE.

THE BRAKE LIGHT IS OUT AND A SINGLE TAIL LIGHT IS OVER 500$ Very dangerous to have tail light out and can cause an accident. There should be a recall on these defective LED lights.

My vehicle started making a knocking sound and eventually died on me. I barely made it to a repair shop to check out my vehicle, but had to get it towed back to my home from the repair shop after they told me my engine failed. This happened around 118,000 mileage. I found out that this issue is very common and needs to be addressed for this year and model vehicle. It could have ended very badly for me as I was on the interstate when it happened. Now, my vehicle is sitting and I am unable to use it. Engine would cost me over $12k for cost and repairs.

The contact owns a 2017 GMC Yukon. The contact noticed that the chrome on the rims of the vehicle was oxidized. The vehicle was taken to an independent mechanic who replaced the rims. The manufacturer was not made aware of the failure. The failure mileage was approximately 90,000.

At low idle speeds like in a parking lot we almost hit another car because the brakes were very hard to press. No power brakes. Felt as I was having to stand on the brake pedal with both feet to stop my vehicle from hitting another car at a grocery store parking lot going 5 mph! A light flashes on and says”service brake assist “ light goes away and drives normal and brakes normal except when you get to a stop sign, or traffic light. This happens a few times and I’m not driving the car because of it because I might hit someone

Yukon break tail lamp problems. Brake lights work intermittently. Very dangerous! The break lights will work intermittently and then work. This was an issue with the 2016 models and GM issues a recall. There is no recall for 2017 which I don't understand because nothing has changed with the manufacturing process. I researched and there is a class action but in California only.

Full engine failure

116k miles and the transmission went out. Spent almost 6k on a jasper to replace it. I don’t think I need to explain what happens when a trans goes out. It did all of those things.

I brought a 2017 Yukon GMC from a dealership. When I first drove it on a highway it began to pull and shake, to the point it slow down on the highway. Also the dashboard started to shake , vibrate on the highway. When I step on the gas on a local road ,the transmission is pulling to pick up speed. Took it to a Mechanic and explained to him what was going on he test drove it and told me it's the transmission. He also said this year truck " GMC" truck like this has bad transmission. I did my research and find out that it is true. I have a disabled mother that I take to her doctors appointment and I'm scared bto out her in this truck. This is a 1 vehicle and anytime the truck will just slow down or vibrate or shake. No check engine light comes on when it happens.ifni driving on A highway sometimes the check engine light will blink 3 to four times then go back out.

The information screen on the gauge cluster sometimes will stop working. This is dangerous as It is the only part that shows if the vehicle is in Park, Reverse, Nuetral, or drive. It also is the only part that shows the vehicles fuel level, blinker, cruise control, temperature and other warnings and controls. This is a common problem for the 2015- xxxx Yukon and Tahoe.

Engine Failure while driving, almost causing me to wreck on the highway.

My 2017 GMC Yukon SLT,, has been having shifting problems, including hard or delayed shifts, clunking, jerking, and even sudden jolts when downshifting.Rough or jerky shifts, particularly during acceleration and deceleration, a delay in engaging gears, especially when shifting from park to drive or reverse. Transmission shifts are very rough in slow traffic with as much as one to two-second delays in shifting into gear with a loud thump. It is so rough that it feels like someone may have ran into your back bumper. It is also bad enough that it startles the driver, and it could be a safety issue

Magneride defect - struts leaking !!! 85,000 miles This is unacceptable- car is dangerous- bouncing - rough ride- shaky- jerking Should be a recalll! Look it up online- many many complaints!

The contact owns a 2017 GMC Yukon. The contact stated upon starting the vehicle, and while driving at various speeds, there was an abnormal ticking sound coming from the engine. There was no warning light illuminated. The contact stated that the abnormal ticking sound had gotten louder. The vehicle was taken to the dealer, and to several independent mechanics; however, the cause of the failure could not be determined. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 181,000.

The vehicle main information cluster randomly goes in and out and now has completely stopped working. This is the information display that shows Park, Nuetral, Drive, Reverse, Fuel gauge, digital MPH and other information such as oil tire pressure, turn signals, forward collision. Just knowing if the vehicle is in Park Reverse or Drive is a huge saftey issue. This seems to be a common problem on GM vehicles and i wcan't seem to find a recall issued for the saftey factor that the vehicle can be assumed to be in Park and it's actually in Reverse. The first time I noticed this problem was Sept. 05, 2020 but it had reset when I restarted the vehicle. The problem would resurface occasionally but always came back on when restarting the vehicle. But know it seems that restarting the vehicle is not fixing the problem and the screen has been blank for the last 3 days.

The air condition lines that feed the rear compartment of the vehicle rub above the rear tire and put a hole in the line. The cost to replace was $2,000. Bad design

Transmission went out in August of 2023, had to have it rebuilt and costed 9,000. Safety was put at risk due to car sputtering to shift gears on the highway while traveling. Problem was identified by the dealership. No light indicators were on. Vehicle now has engine starting to come on periodically and when trying to diagnose it is giving fuel efficiency codes.

According to dealership Front and Back Suspension - SHOCK &/OR Struts - According to all complaints online it could be the Magnetic Ride Control- Car is a danger!!!!!! This car bounces all over the place - rides rough and bumpy!!! This should not be happening at 84K miles!

Lifters failed

Brake pedal gets hard and will not allow vehicle to stop. Intermittent issue, but caused vehicle to hit gate. Same situation occurred later that same week and vehicle almost rolled through major highway crossing.

RPM’s started to fluctuate while driving with cruise on. Noticed no issue with shifting until torque converter grenaded blowing metal through the transmission 2 days later. Transmission has been replaced with GM reman by a GM dealer. New transmission lags going into gear when it’s cold and shifts hard. GM tech said this is common and no way to correct it without replacing it again.

Transmission jerks, shifts hard, loses power… Temp gets 199 just driving… Humming sounds, taken to dealer three time… 188,000 miles…

The pump in the power-assist brakes puts out less vacuum power than needed, increasing stopping distance and the risk of a crash. My car rolls and doesn't stop. I have new brakes so this is unacceptable!!

High pressure fuel pump regulator failed and cause gas leaking, reduced engine power and gas smell coming back in vehicle. It was also blowing out white smoke. It had delayed ignition starting. The engine light did come on. Several makes and models of GMC has had recalls for this problem. The 2017 GMC Yukon was not included for this recall and should have been.

My transmission does not engage properly. From a starting position when I step on the gas the transmission lags and when it catches it slams / bangs into gear

Clutch in Torque Converter failed at just around 60,000 miles. Vehicle had a vibration issue shortly before & I thought maybe I got a poor quality tank of gas. Filled up with new gas and problem still there. Took it to my mechanic & he told me it was a complete failure which would require a new transmission or a rebuild on existing.

I have a 2017 Yukon. There is a recall on this model already for a vacuum pump that decreases the power brake assist. My vehicle is having this exact issue. The back tire sounds like the compressor is always running and when braking it grinds at the pedal like a vibration and doesn’t want to stop immediately. I need my vehicle added to the recall list so I can get it repaired.

I bought the vehicle in October 2024 ever since then I have been trouble with the differential, the automatic starter doesn't start the vehicle unless you are at least one feet away from the vehicle. I drove to work when I got off and got in my vehicle my check engine light was on. The vehicle was saying there was an issue with the battery, antilock braking system. I bought an extended warranty up to 150,000, I currently have 63,400 on my vehicle. Empire Buick GMC of White Plains has not been honoring my warrantee, I had to rent a car to get back and forth to work because of fear of riding the NYC subway.

The contact owns a 2017 GMC Yukon. The contact stated that while depressing the brake pedal, the driver’s and passenger’s side taillights failed to illuminate as designed. The contact called the dealer about the failure and was informed that there were no recalls or warranties on the vehicle associated with the failure. The contact was also informed that the repair would be an out-of-pocket expense. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 64,000.

I was driving my car and it started making "clanging" and "banging" noises and jolting/jerking forward. It was scary to drive because of the noise and the jerking foward. I was afraid that my car was going to just stop working, I would get stuck/stranded somewhere or my car was going to blow up. I brought it in to the dealer two times. The first time they thought it was the battery so they replaced the battery but that didn't fix the problem. The second time I left it there for days and they told me that I needed a new transmission. The problem was reproduced and inspected by them. There were no warning lights or messages prior to the failure. The problem started on approximately January 6, 2025. Online, I have read from other sources that 2017 - 2020 GMC YUKONS are know to have transmission problems. My car only has 58,000 miles on it, has been serviced consistently, and should not need a new transmission at this low mileage point.( 150,000 to 200,000 is the norm for transmission replacement)

Not even 100,000 miles on it and the engine blew. Started with a lifter issue. Everyone I talk to with Yukons and GMC in general say it’s a problem. Just a search on the internet shows that they all have this issue… a well maintained car should not have this issue and it’s clearly a GMC issue and it needs to be fixed. The repair shop can’t even order me a new engine due to this being a real problem all over with GMC.

I am submitting this complaint regarding a persistent and significant transmission issue with my 2017 GMC Yukon Denali, which I purchased in June 2024. The transmission has been malfunctioning, causing the vehicle to jerk and hesitate, particularly during acceleration. This component is available for inspection upon request. Safety Concerns: This issue poses a serious risk to my safety and the safety of others on the road. The jerking and hesitation during operation can result in delayed acceleration or unexpected speed changes. These problems have occurred while merging into traffic and driving on highways, creating hazardous situations where immediate and reliable vehicle performance is critical. Reproduction and Inspection: The problem has been reproduced and confirmed by an independent mechanic who inspected the vehicle. The diagnosis identified a transmission malfunction, which appears consistent with reports from other owners of GMC Yukon models. However, the vehicle has not yet been inspected by the manufacturer, police, or insurance representatives. Warning Symptoms: There were no warning lamps or error messages displayed prior to the onset of the issue. The jerking and hesitation began soon after I purchased the vehicle in June 2024 and have progressively worsened over time. I have discovered that GMC has issued recalls for similar transmission issues in later Yukon models (2021 and 2022). However, despite widespread complaints, earlier models like my 2017 Yukon Denali have not been included in these recalls. Given the safety risks associated with this transmission defect and the frequency of similar complaints from other owners, I urge the NHTSA to investigate this matter. Prompt action is essential to ensure the safety of drivers and passengers in affected vehicles and to hold the manufacturer accountable for addressing this defect.

the lifter is stuck an making a clicking noise an where on the high an truck cut off let it set for a minute then it crank by up an drove to a shop an they said it was a lifter stuck sounded like number 2 lifter this needs to be covered by gmc as a recall.

Transmission shutter causes the car to vibrate which could lead to transmission failure.

The contact owns a 2017 GMC Yukon. The contact stated that after starting the vehicle, the vehicle was vibrating abnormally. The front of the vehicle was shaking. The contact stated that while at a stoplight with the brake pedal depressed, the vehicle stalled but independently restarted. The engine warning light flashed on and off. The vehicle was taken to the local dealer, where it was diagnosed with transmission and engine failure. The vehicle was repaired, but the failure recurred. The manufacturer was contacted and confirmed there were no recalls on the VIN related to the failure. The contact was referred to the NHTSA Hotline for assistance. The failure mileage was approximately 50,000.

Vehicle Malfunction Incident Report On [11/2724], while stopped at a traffic light, the vehicle experienced a sudden and significant loss of power and gear shifting capabilities. The engine accelerated, but the vehicle struggled to move and shift gears, making it difficult to cross the intersection. After a short distance, the vehicle accelerated again, but there was no forward movement. The vehicle was subsequently parked in a nearby neighborhood, where it became completely immobile. Attempts to engage reverse or drive were unsuccessful. The vehicle emitted a loud noise, and a check of the transmission fluid and other fluids revealed no issues. After turning the engine off and restarting, the vehicle was able to engage drive, but it was limited to second gear. The vehicle then lost momentum again, making it difficult to reach home. It is important to note that no engine light illuminated during the incident, and there were no visible fluid leaks. All routine maintenance has been performed according to the manufacturer's recommendations. A mechanic has inspected the vehicle and diagnosed potential transmission issues. Requested Action: We request a thorough investigation into the cause of this malfunction. We believe that a transmission issue is the likely culprit, but further diagnostic testing is necessary to confirm the exact problem. We have seen that this has been a reported issues with these vehicle and the manufacture has not done anything for recalls.

I was taking my client to school. I stopped at the stop sign. When I pushed gas pedal to go, my truck did not go, it strained did a big jerk then went. The next morning it did the same thing & later on that day, it did it again. Two days later I had to stop at red light. When the light turned green I pressed the gas pedal & nothing. It did not go at all. I turned the ignition off and back on twice & put it in drive still did not go but was slowly going backwards. A by-stander stopped to assist me getting my truck out of traffic.

Transmission failed on the freeway with no signs signaling issue before hand at 109,000 miles. Also lane departure does not work often. And suspension gave out at 60,000 miles.

The contact owns a 2017 GMC Yukon. The contact stated while driving at various speeds, the vehicle started jerking and hesitating while shifting gear. The vehicle was taken to the local dealer to be diagnosed and the contact was informed that the transmission 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 140,000.

Lifters failed 2nd time at 130k miles. Driving on highway at 70mph cruise and engine went to limp mode. Multiple repairs. $5,000. Dealer sold it to me in 2020 with 80k miles and did not disclose prior lifter replacement. I know they did something as a head bolt is missing.

The steel bar could be felt through the lower lumbar area. Seat back also moved out of position while driving and I was told the bar inside the back came out of place.

Stabilitrak warning light comes on intermittently. Cruise or anti-lock brakes do not work when this condition is present

Tremendous transmission shudder prevented me from properly accelerating from a stop light thereby causing a dangerous traffic backup issue in a congested area.

I was stopped at a red light in the left hand turning lane and when the light turned green I proceeded to accelerate and the engine would rev but the car would not move forward so I continued to push on the gas when the car jolted forward Violently. I am lucky no one was in front of me because this would have cause a car accident. Turns out the transmission had failed and needed to be replaced which is a common issue for GM however they never owned up to it and refused to pay to for the cost of the replacement and I paid several thousands out of pocket. This is a major safety concern and could be potentially life threatening. GM should recognize this as a recall and take ownership of a failed transmission with less than 100,000 miles.

The contact owns a 2017 GMC Yukon. The contact stated that the A/C System was inoperable. The vehicle was taken to the dealer, where it was diagnosed that the A/C condenser had failed and needed to be replaced. The vehicle was not repaired. The contact related the failure to GM Campaign Number: N162080780. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 57,000.

Tail lights went out. Lifters have been replaced TWICE! While stopped at red light, at take off the vehicles lunges forward. At low speed the vehicle will down shift on it’s own. 80k miles Recently while headed to work, the torque converter went out. 126k This is suppose to be a luxury vehicle and cost entirely to much to be a POS. I honestly thought I had a lemon but it seems to be a reoccurring issue in the entire fleet.

The SUV was stalled after getting in D to drove forward and all of a sudden it’s started with a big jerk and moved forward It went driving ok for them rest of the day but it kept repeating the incident n and off until June 15 when it was stalled on a traffic light I was able to put the emergency flashers and drive it in reverse to a near by parking lot

1.)Rear Brakes are not functioning properly. They still have pads but when you press down to pump the brake it fails. I was told by a mechanic that they other GMC vehicles have had recalls on this, but mine is not showing one. 2.)The suspension on this vehicle has never worked properly. It rides extremely rough. It has some special suspension in it from a shock perspective, but it feels as if it often fails. 3.) I had to replace the torque converter in this vehicle last year, and the fluid that runs through it. Apparently this is a known issue with no recall. 4.) the transmission slips when the vehicle shifts gears. It shifts hard. Also a known issue with no recall.

AC stopped blowing cold air while driving

Tranny failed at 92k miles even though properly maintained. Since new tranny installed by dealer (out of pocket cost) had to return due to tranny slipping into neutral when driving highway speeds and taking foot off gas. Dealer performed TCM and ECM flash updates. Cost out of pocket for programming. Issue came back less than 2000 miles later

Info screen black not showing backup camera view

Rear LED taillights circuit boards broken. Disabling both Stop tail lights causing serious safety hazard. We had no clue driving around and we didn't have any brake lights another driver had to tell us. So we googled this problem and it turns out that all of 2017 GMC Yukon have the same issue. There's even multiple websites to repair them as well as auto supply stores selling replacements for $1,000 and the dealership wants $1,500. This is a real problem and GM needs to make this right and recall all of these and replace them before somebody gets hurt if they haven't already.

This happened 5 years ago but I never reported it. GMC 2017 Yukon. I put my SUV in park, and entered and exited it several times while parked in my driveway. When I went to grab my purse (standing at drivers side door, reaching for purse on passenger seat) the car rolled. I was on a sloped driveway. The car rolled backwards, and I tried to jam it into park more strongly, but it just made a grinding noise and kept going. I was knocked over by the car door, pulled under the car and ended up having my legs run over by the car. I sustained injuries which affect me to this day. I was transported to the hospital by an ambulance after a 911 call, so I presume there is a police report. I was injured and dazed. This happened on [XXX]. I am only reporting it now since I never thought about doing so before I read an article today about cars being recalled for this problem. If other people have my model of car and this is a problem, I would want them to know. I was thinking maybe I hit the gear shift with my purse and knocked it out of park, but this should not have happened without the brake depressed. I was standing next to the drivers side door when this happened. I did have the car taken to the dealership to be examined, and they said it was ok, but could not really explain how this happened. I still have this SUV but am very cautious about any situation where the car could roll when in park and cause injury. The car crashed into a tree and that stopped the rolling. Has there been other reports of this happening with this model of car? I would like to know, because if there is a problem that has come to light in this, I will get a different vehicle!

Rear (Tail/Stop) lights on both sides, would work intermittently. Turns out it’s a known issue with the LED circuit boards. They consistently break in 2 places, leaving the vehicle with no tail lights/stip lights. GM knows of the issue , but since it’s NOT CONSIDERED a Safety Issue, they do nothing. It’s clearly a safety issue, as following drivers may not see lights, on the rear. Clearly, it is definitely a safety issue, as it can easily cause an accident, not knowing a car is there in the dark , or not knowing that the vehicle in front of them is on the brakes, and slowing.

Transmission /torque converter I was driving on highway and all of a sudden what seemed like the engine lost power and I could not accelerate. After heading to slow lane and few seconds later everything went back to normal. A week later same thing happened but this time it wouldn’t shift to second gear. I was stranded on side of road. Before calling help , I let it idle for a few minutes and tried again to put in drive, it worked again. I made it home. Next day it just started making a loud noise under truck. Was able to get a mechanic and he said it’s the transmission. Has 103k miles and is out of warranty

The contact owns a 2017 GMC Yukon. The contact stated that while driving at approximately 45 MPH, the brake pedal was depressed; however, the brake pedal remained on the floorboard. The contact stated that the vehicle was driven until the vehicle eventually slowed down. The vehicle was taken to an independent mechanic where it was diagnosed and determined that the rotors and brake pads needed to be replaced. The vehicle was repaired but the failure persisted.

The manufacturer was notified of the failure. The failure mileage was 85,000.

Lifters

Driving down the highway and brake pedal became hard to push down almost causing us to wreck. Keep seeing there was a recall for the brake vacuum pump and also brake assist warning came on. Also when driving low speed like in parking lot it takes a while for vehicle to come to a complete stop

my acceleration is sticking.. have 11322 miles when i accelerate to get on freeway gas pedal gets stuck .. had to put it in neutral

The contact owns a 2017 GMC Yukon. The contact stated that while driving at 20 MPH, the vehicle slipped out of gear, causing the vehicle to independently slow down. No warning light was illuminated. The vehicle was taken to a dealer to be diagnosed. The contact was informed that the failure was due to a faulty transmission. The contact was informed that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 80,000. The VIN was unavailable.

Tail Brake Light failure The tail brake lights have gone out on a vehicle that isn't 10 years old yet. Tail lights should not go out this quickly and the dealership will kindly replace them at $1300 per tail light. This is absolutely absurd! It is available for inspection. This definitely puts myself and others at risk! Yes, this problem has been confirmed and inspected by a GMC dealer. Advised this is a very common problem with this vehicle. There are no warning lamps or messages to alert when the brake lights have gone out. Instrument Cluster failure The instrument cluster is also faulty in this truck. This is the 2nd time within a year that i have had issues with this. Safety concern is that you will not know if the vehicle is running hot because the gauges stop working. Also runs the battery down as the fan continues to run for about 10 minutes after the vehicle is turned off. Yes, the problem has been confirmed and inspected by a dealer. Advised that this is a very common problem with this vehicle. No, there are no warning lamps or messages to alert you of the problem. You just notice a different noise while driving, the gauges stop working and then when you turn it off, the fan continues to run.

The engine light has come on spuradically for the last 1.5 years and has been consistently on since May of 2023. This starting approx. 95,000 miles. During this time after starting the Yukon it is chuggy and missing, as I drive off it jerks and darts forward. Seems to be when I stop and start to go this happens, again engine light is always on...sometimes flashing. Starting 9/19/23 (106,000 miles) when slowing down to turn into a parking lot the engine revved high, no movement with the touch of the gas pedal and suddenly takes off with a jerk and a squeal of the tires. VERY SCARY. Since then I have experienced this DAILY, at least once a day. So far it is when I am going slow, either taking off and accelerating or slowing down. The engine and RPMS rev up and go high with no way of moving when touching the gas pedal then suddenly jerks and takes off with the tires squealing. I am also experiencing the transmission shifting VERY hard, mainly when slowing down. I am feeling very timid and scared to drive this vehicle...this is a seriously dangerous situation and can cause a serious accident or life! I believe this fits into the description of the GM Class Action Lawsuit filed over transmission problems. When I previously talked to the dealership they kept saying that there was no recall for the problems and to bring it in. I am not going to continue to get things fixed that do not fix this problem, as I have already. I know of a friend who has the same vehicle/year only a Tahoe and is experiencing the same problem and had work done at a dealership with no fix for their issue neither. Something has to happen with this problem from GM! The contact stated the issue has gotten worse pushing down the gas pedal rendering the vehicle immobile, then all of a sudden it jerks and shifts into gear jolting the vehicle forward.

The rear taillight has gone out. The LED board has a crack in the soldering causing the entire unit to malfunction.

LED brake light works intermittently.

The contact owns a 2017 GMC Yukon. The contact stated that on several occasions while the vehicle was parked, the passenger’s side rear taillight failed to illuminate. The vehicle was taken to an independent mechanic where it was determined that the full assembly light kit needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the issue. The failure mileage was approximately 80,000.

Rear brake lights fail due to an issue known by GMC - MULTIPLE GMC YUKON and YUKON XL have this issue. All within the same year. The metal connector in the Brake housing fails and requires it to be soldered or a complete replacement costing consumers $800+ for replacement. A severe safety issue as the Brake Lights quit working!!

At traffic light in drive position, shifting drags when accelerated and hard shift jerk , slipping gears or driving and not shifting at all

Rear tail lights failure.

LED brake lights and tail lights not working on passenger side. Partial LED failure on driver side.

service brake assist light, needed to press brake pedal harder to stop, a ticking noise coming from engine compartment.

The retractable side steps on the passenger side retracts while still getting into the vehicle. It almost catches the entire foot in the door. It’s a safety hazard for my children and parents. It is currently an out of pocket expense and my vehicle has less than 55000 miles on it. It has happened multiple time including today.

The right side break light works intermittently. It is out more than on. I was informed that there is a shortage in it and the entire assembly has to be replaced. I see countless GMC Yukons with the same light out. This is a huge safety issue.

OUR VEHICLE IS 2017 AND WE HAVE TO REPLACE THE AIR CONDITIONING CONDENSER. I'VE READ THAT THIS A ISSUE WITH THESE VEHICLES AND IT IS VERY EXPENSIVE TO REPAIR. THIS PROBLEM. THERE SHOULD BE A RECALL IN PLACE. WE AS CONSUMERS SHOULD NOT HAVE TO PAY FOR THE NEGLECT OF GMC NOT PROPERLY BUILDING THIS VEHICLE.

The transmission was jerking jumping and was replaced under warranty and it still can not be fixed. Cause the vehicle to jump backward and hard speed.

The passenger taillight failed.

AFTER A 7 HOUR DRIVE ON FREEWAY BRAKES FAILED TO STOP VEHICLE. I HAD TO HAVE IT TOWED TO REPAIR SHOP FOR A COMPLETE BRAKE JOB FOR $1800.00. VEHICLE SEEMED TO BE FIXED SO DROVE IT BACK HOME ANOTHER 7 HOURS AND THE EXACT SOME PROBLEM HAPPENED AGAIN WHILE PARKING IN MY GARAGE.

Transmission, radio is skipping, brakes

Ac just stopped working at 100,000 miles

The contact owns a 2017 GMC Yukon. The contact stated while driving from a complete stop, the vehicle hesitated to respond while shifting from first to second gear. Additionally, the contact stated that while driving at various speeds and depressing the brake pedal, the brake pedal would hesitate to respond, causing a 40-50 feet stopping distance delay. There was no warning light illuminated. The contact stated that the failure recurred while driving. The vehicle was taken to an unknown dealer who advised the contact to take the vehicle back to the Honda dealer where the vehicle was purchased and sold for repair. The vehicle was taken to the Honda dealer. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 120,564.

My 2017 GMC YUKON’S TRANSMISSION IS DEFECTIVE. THE SUV WILL JERK AND JOLT WHEN SHIFTING GEARS. IT IS EXTREMELY UNSAFE TO BE DRIVING WHEN YOU NEED TO RELEASE THE GAS PEDAL AND PRESS DOWN AGAIN IN ORDER TO SHIFT PROPERLY. THIS CAUSES AN EVEN MORE SUDDEN JOLTING. THIS IS EXTREMELY UNSAFE AS A FAMILY VEHICLE ESPECIALLY WHEN YOU HAVE A NEWBORN. I ASK A RECALL BE SUBMITTED SINCE I SEE SEVERAL REPORTS OF A SIMILAR ISSUE WITH THE 2017 GMC YUKON.

2017 Yukon Denali manufactured in 2016. It requires the exact same repairs as the 2016 service bulletin N192291660. My Transmission wiring Harness must be replaced including the gasket and filter. The Global Safety Feild Investigation DCS5461 only included 2016 and not car manufactured in 2016 and labeled as 2017. I have the exact same error codes p0711. The Global Safety Field Investigation was issued in July 29, 2020.

First problem started back in May.. it’s went downhill ever since. Hard shifting was happening. GM dealer said I needed a new transmission. Found out from local repair shop that I needed a torque converter ($600) multiple transmission fluid changes (apparently many issues for A Lot of people) changed that. Then had to change Valve Body & TCM. ($540) everything started working but not 100% did a full tune up having multiple misfires constantly then shuttering when idle. Also replaced ECM ($200+)After changing all spark plugs, wires, oil, etc. the AC was having issues had been having issues for months. Kept adding Freon had to replace AC Condenser (works great now, was told by repair shop that’s also very common in these year models. Condensers are all weak in the same spot) just recently October 2022, my instrument cluster started going haywire. Gauges going off and on screens going blank. Had Alternator and battery tested both test fine. No loss of power but when hitting the start/stop vehicle would continue to run and lock and unlock when it wanted. Husband took the alternator out to have it tested again. They tested 3x 1st. Good, 2nd Error, 3rd Bad ( it was overcharging at 16.5V) replaced Alternator ($290) gauges still going haywire, like before it is only sometimes, when they do it’s bad bad.. but I can also drive to town and back 20-30 miles and not the first issue. Just left GM with a new Battery Distribution Fuse Block ($153) because of course it can’t just be a regular ($8-10) mega fuse, hopefully this will fix my issue. We pay too much money for this vehicle to have all of these issues & none be under warranty. I’ve been having the TAILLIGHT ISSUES as well ever since I purchased the car in 2018. When I received the recall on the taillight it was 6 years up to 72,000 & of course my vehicle had 79k miles on it at that time so that’s wasn’t covered.

The contact owns a 2017 GMC Yukon. The contact stated while stopped at a traffic light, the accelerator pedal was depressed; however, the vehicle failed to respond. The contact stated there was no warning light illuminated. The contact stated a Police Officer assisted in moving the vehicle out of the roadway. The vehicle was not drivable. The contact towed the vehicle to the local dealer however, the mechanic was unable to duplicate the failure. The vehicle has not diagnosed the vehicle nor repaired. The manufacturer had been informed of the failure. The failure mileage was approximately 77,000.

The contact owns a 2017 GMC Yukon. The contact stated while driving at 20 MPH with her daughter in the rear passenger seat, the message "Grade Braking Active" was displayed. The contact stated while making a right turn in an intersection, she depressed the brake pedal to prevent the vehicle from colliding with the vehicle before hers. However, the brake pedal went down to the floorboard and failed to respond. The contact then quickly veered to the right to prevent a crash. The vehicle hit a curb and was propelled to the left across three lanes and crashed into the rear of another vehicle. The air bags did not deploy. The contact sustained bruises on the forehead as she hit her head against the steering wheel. The contact also sustained soreness on the neck and shoulder; however, the contact did not seek medical assistance. The contact's daughter did not sustain any injuries. The occupant of the other vehicle did not sustain injuries. A police report was filed. The contact's uncle met her at the scene and drove the vehicle back to her residence. The dealer was not notified of the failure. The manufacturer was notified of the failure and informed the contact that they would send a field technician to diagnose the vehicle. The contact associated the failure with NHTSA Campaign Numbers: 19V645000 (Service Brakes, Hydraulic) and 20V603000 (Service Brakes, Hydraulic); however, the VIN was not included. The vehicle was not diagnosed or repaired. The contact's vehicle remained at her residence. The failure mileage was approximately 95,000.

We took the car into the dealership and complained about the AC and the vehicle being new and they said it was a common problem with this vehicle and offered 10% discount.

NHTSA Campaign number: 18V586. GM’s number for this recall is 18289

What component or system failed or malfunctioned, and is it available for inspection upon request? - Airbags How was your safety or the safety of others put at risk? - Airbags did not deploy during the car accident. Has the problem been reproduced or confirmed by a dealer or independent service center? -No 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? - None.

I purchased a 2017 GMC Yukon Denali brand new off the showroom floor. I have maintained the services thru GMC dealership. I had to replace the struts and rear and front shocks due to hydraulic system leaking and locking up my brakes and causing extra pressure on my braking system to stop my vehicle. This cost me over $5000 to replace out of my pocket and I saw there was a previous recall in 2019 for similar problem but i was told my issues were not covered under the recall. I have also had to replace both taillights within 2years of purchasing my brand new vehicle and now they are out again. This will be my second time having to replace the LED tail lights that cost over $375 light which were stated as never go out of lifetime guarantee. You cannot just replace the bulb you have to replace the whole tail light which takes weeks to come in and then additional labor costs. The previous

Presently my air conditioner in my 2017 Yukon Denali has went out around 55 thousand miles approximately .We called to make appointments many times & after several attempts finally my car was early one morning & left until about 4:30;no one called to tell my husband not myself that their machine was not working.So no I’m order to wait for another appt !Today June 27th they are finally checking my air conditioner.I received a call saying this would be 1200.00 dollars!I bought this car with 23 miles on it and 6 MONTHS AFTER I DROVE IT I TOLD MY HUSBAND SOMETHING DI NOT SOUND RIGHT NOR FEEL RIGHT .We tried to make Many appts for 3 years UNTIL GMC FINALLY ADMITTED THERE WAS A RECALL!!Im furious.My vechile would cut off in the middle of a main Hwy with my 9 year old with me.Automatic brake will stop me at 55 mph ;for no reason .Windows down sound like you are in a wind tunnel !!Sun roof leak .Middle console latch just stopped working .ENGINE PROBLEM STILL NOT FIXED & UNDER LEMON LAW AFTER 3 attempts,& with all the lies many GMC LOCAL DEALERS HAVE TOLD ME DUE TO JUST NOT WANTING TO ADMITT THE TRUTH.I feel unbelievably frustrated.

Driver’s side rear Tail light stopped working. It’s not even 5 years old. Bought August 2017 Brand new. I know there is a recall on 2015-2016 models for the same problem.

Low speed breaking failure.

My vehicle began shuddering during acceleration and would violently jerk forward after gas pedal was engaged with decreased power in forward acceleration and increase in rpm. This last a couple of weeks. Now, my vehicle is completely broke down and at a GM certified service center. The Service manager states torque converter completely went out and the transmission is burnt up. The mileage is at $61,000, so GM warranty won’t cover it and the company that holds the extended warranty I purchased hasn’t been able to be successfully contacted. There is a “service” bulletin but no recalls and a class action lawsuit (that I’m not a part of) but no recall. My vehicle completely lost power going 50mph on a busy road without warning. This needs to be a recall due to this dangerous circumstance.

-Back brake light system failure. -Safety of a rearend accident compromised when tail light does not work properly. -Yes, a repair shop confirmed the $975 unit needs to be replaced and is on back order for one month putting our safety at risk. -No warning has appeared. A person behind me reported it to me.

Passenger brake light stop working. Had the dealer ship inspect the light and was informed that the whole unit had to be replaced at a cost of $1000. so I purchased the part for $800. and replaced it myself tech. informed me that GM had a recall on the 2015 and 2016 model's but has not included the 2017 model year

Rear tail / break light no longer works .

Brake light not working.

Water in 3rd brake light

Tail lights do not work when I press the brakes. I have been warned multiple times by drivers.

Both the passenger and driver side tail lamps have failed and the assembly had to be replaced.

The contact owns a 2017 GMC Yukon. The contact stated that while stopped at a stop sign, the brake pedal was depressed however, the passenger’s side rear taillight failed to illuminate. The vehicle was not taken to a dealer or independent mechanic to be diagnosed or repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 53,570.

Taillights and Brake light LEDs go out unexpectedly or work intermittently creating a safety hazard that drivers behind the Yukon are unable to see your taillights at night or when your braking causing Potential rear end collisions. For this common problem GM recalled the taillights of 2015-16 models, but the 2017+ models that still have the same exact taillights with the same issue but has not been recalled yet. Costing owners out of warranty $800 per taillight assembly. Please look into this safety issue.

The left rear tail light has gone out. There is no user replaceable bulb and this is a sealed unit. The deal has quoted almost $800 to replace. I feel a sealed unit should not fail prematurely and should last the entirety of the life of the vehicle. Had it been user serviceable, this would be a simple repair/fix.

Brake light on the passenger side has failed and non operational. I have researched this and found it is way to common to not be a manufacturer design issue.

LED taillights have both gone out. One was replaced by a "service bulliten" and it didn't cost us. The other recently went out at approx 80k miles. These are supposed to last the life of the vehicle. Replacement cost is $750. After doing research, there is a recall for 2015-2016 GMC Yukon taillights that are the exact same product. I contacted GMC and they refuse to replace the known defect part. This is going to cause someone to get seriously hurt. They know the part is defective or they wouldn't have had a recall on the 2015-2016 models.

The transmission failed while merging and almost caused a collision. After a complete transmission replacement, the fuel injectors failed causing the same issue. GM extended fuel injector warranty due to the number of similar issues, but not in my state.

The contact owns a 2017 GMC Yukon. The contact stated that while using the remote start-up feature, he noticed that the rear passenger's side brake light and taillight were inoperable. The vehicle was taken to the dealer and diagnosed that the taillight assemblies needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was 41,169.

Air-Conditioning condenser failure (Special Coverage Adjustment 173326 Air Conditioning Condenser (Combi-Cooler) Refrigerant Leak) According to GM they say my VIN is not on the list...however, I'm having the exact same issue on my 2017 Yukon with 38k miles on it.

My tail light is faulty. It is working some, shorts out, stops working, I hit a bump, it starts working again. Almost caused a crash, the lady followed me to the store to tell me it was out. Took it to the mechanic and it was working again without any repair. Does this everyday.

My car is not shifting right. I took it into GMC, and they said they corrected it. I have taken in two times for this issue already. Today I almost was in a car accident because the car would not shift properly and it shoved me forward like A car hit me from the back. The car is not shifting properly at all. And now it’s making a muffling sound and it’s like stuck in a gear. I pulled over and I parked and then I reversed and then I went to hit the gas again to try to go slowly and it jolted forward again. This is serious and needs repaie

2017 GMC Yukon Denali 4WD. Rear passenger brake light intermittently fails while driving Confusing and causing motorists behind my vehicle to receive inconsistent intermittent brake warning lights to alarm other motorists I have stopped. Someone is going to end up slamming into me because of this. It’s a dangerous common failure that needs to be address ASAP. I’m not waiting but GM’s executive corporate office will get the entire bill plus time lost and another BBB review.

My husband and I were driving down the freeway with our three children when without any warning, we heard a loud explosion and what felt like something hit our vehicle. There were no other cars near by. When we pulled off the freeway into a gas station to look at the vehicle the sunroof had a huge hole in the center. The remaining class attached to the vehicle was all shattered. There was shattered class on the closed shade. We didn't know what happened. It was very traumatizing. We thought someone threw something at us or something had fallen on the vehicle. If the sun shade wasn't closed, glass would have entered the vehicle and could have caused injury to us or our children in the back seats.

The driver's side brake light and tail light has failed completely and the passenger side brake light and tail light fails intermittently. This is a safety issue that should be recalled. The vehicle only has 50k miles on it and I should not have to pay $800 per tail light to fix it!

The steering wheel doesn’t always turn back straight like the electric power steering has a momentary lapse in working.

Brake lights quit working

There is a known issue with the GMC strutts leaking. I contacted several GMC dealerships to purchase strutts so that a local mechanic could put fix my truck without the dealership pricing. GMC refuses to sell the parts to anyone other than a dealership. I was informed by several dealerships the part is a national back order for 6 months. The cost that GM is making for each person that purchased a 2017 Denali is between two to four thousand dollars!! While driving my truck myself and my daughter would come out of the seat! This should be a recall. I'm also reporting this to the consumer financial protection bureau. I phoned this in a month ago and have heard nothing.

BRAKE LIGHTS INTERMITTENTLY WORK. WILL COME ON SOMETIMES AND THEN GO OUT. THIS HAPPENS WHEN THE CAR IS STILL AND WHILE MOVING.

LEFT AND RIGHT BRAKING LIGHTS SOME TIME DO NOT WORK WHEN BRAKING. ONLY THE REVERSE LIGHT WILL WORK WHILE THE BRAKING LIGHT WILL NOT. TO ADD, WHEN THE FRONT HEADLIGHTS ARE ON, SOME TIMES THE LEFT AND RIGHT TAIL LIGHTS (LIGHT THAT IS ON WHEN NOT BRAKING) AND BRAKING LIGHTS WILL NOT WORK. I HAVE HAD TWO DIFFERENT PEOPLE PULL UP NEXT TO ME SAYING MY BRAKE LIGHTS ARE OUT IN THE LAST TWO WEEKS. HOWEVER, I HAVE OBSERVED WHEN THEY ARE WORKING IN THAT SAME TIME SPAN. THE LAST TWO DAYS, ONLY THE RIGHT TAIL/BRAKING LIGHT IS NOT WORK.

DRIVER SIDE REAR BRAKE LIGHT ISN'T WORKING ANYMORE. 46K MILES ON A 2017 GMC YUKON.

BRAKE LIGHT FAILURE. BRAKE LIGHTS WORK INCONSISTENTLY. CHANGING THE BULB DOES NOT FIX THE PROBLEM. THIS IS AN ELECTRICAL ISSUE THAT HAS BEEN REPORTED BY NUMEROUS OWNERS. THIS IS A SAFETY HAZARD AS THE COMPONENTS HAVE TO BE REPAIRED BY A TECHNICIAN WHICH CAUSES HUNDREDS OF DOLLARS, PER LIGHT. THIS IS A DEFECTIVE PRODUCT THAT SHOULD BE RECALLED!!!

WHEN TRAVELING AT LOW SPEEDS (10-20 MPH), I HAVE CONTINUOUSLY EXPERIENCED "LUNGING" AND "JERKINESS" WITH MY TRANSMISSION FOR OVER 2 YEARS NOW. DESPITE APPROXIMATELY A DOZEN SEPARATE EVALUATIONS AND/OR REPAIRS BY GM-CERTIFIED TECHNICIANS, THE PROBLEM CONTINUES TO EXIST. I AM TOLD THAT THE ISSUE IS NORMAL AND THAT I MUST LIVE WITH THE ISSUE AS BEING NORMAL. NOT ONLY AM I CONCERNED ABOUT THE ONGOING MAINTENANCE COST, BUT THE SAFETY OF MYSELF AND PASSENGERS SHOULD THE VEHICLE STRIKE AN OBJECT OR PERSON ACCIDENTALLY. ACCORDING TO VARIOUS ONLINE SOURCES, THERE ARE HUNDREDS OF GM OWNERS WHO ARE EXPERIENCING SIMILAR ISSUES, AND EVEN A CLASS ACTION LAW SUIT HAS BEEN FILED. HOWEVER, THERE HAS BEEN NO ACKNOWLEDGEMENT OR MEANINGFUL RESOLUTION TO THE PROBLEMS.

THE BRAKE LIGHT IS OUT AND A SINGLE TAIL LIGHT IS OVER 500$

MY 2017 GMC YUKON DENALI CONTINUES TO HAVE A VERY LOUD SHUDDER SOUND AS YOU ACCELERATE.

BOTH BRAKE LIGHTS STOPPED WORKING AT THE SAME TIME. THERE IS NO FUSE. ONLINE REPORTS SHOW MANY PEOPLE WITH THE SAME VERY DANGEROUS, HUGE SAFETY ISSUE OF THEIR BRAKE LIGHTS FAILING. THE CAR 3 YEARS 2 MONTHS OLD.

THE BRAKES STOP WORKING. BRAKE ASSIST COMES ON. WHEN I PRESS THE BRAKES YOU CAN FEEL THE PUMP IS NOT WORKING AT ALL. THIS IS HAPPENING AT SLOW SPEEDS MOSTLY IN PARKING LOTS BUT IN FEAR OF IT HAPPENING WHEN GOING FASTER. THIS NEEDS TO BE FIXED ASAP- DANGEROUS TO DRIVE MY CHILDREN AROUND IN A CAR WHERE THE BRAKES JUST STOP WORKING.

MY CAR A/C HAS A LEAK AT THE CONDENSER, THIS IS A DEFECT KNOWN BY GMC, THEY ONLY EXTENDED THE WARRANTY UP TO 60,000 MILES AND 72,000 ON CADILLAC, MY YUKON ACTUALLY HAS 71,500. THE REPAIR FOR THE GMC DEFECTIVE VEHICLE A/C IS EXTREMELY COSTLY TO REPLACE THE DEFECTIVE PARTS AND OVERPRICED LABOR.

IRREGULARITIES WHEN BRAKE IS PUSHED AT LOW SPEEDS. CAN FEEL VARIOUS ISSUES SUCH AS VIBRATING BRAKE PEDAL, STUTTERING NOISE, LOSS IN PRESSURE OF BRAKES AND NEEDING EXCESSIVE PRESSURE ON BRAKES TO STOP VEHICLE. THIS HAS HAPPENED 2-3 TIMES NOW, ONCE IN A PARKING LOT, IN A DRIVE THRU AND WHEN PULLING OUT/IN THE GARAGE.

TAIL AND BRAKE LIGHT NO LONGER WORKING

FRONT MAGNETIC SHOCKS QUICKLY FAILED, PART NO. SK3354. PART HAS BEEN ON BACKORDER FOR OVER A MONTH, WHICH MEANS IT IS FAILING ON MANY VEHICLES. PART IS KNOWN BY REPAIR SHOPS TO BE DEFECTIVE, BUT THEY SAY THE REPLACEMENT PART LASTS LONGER. GM SHOULD PAY SOMETHING TOWARD REPLACING THIS DEFECTIVE PART, WHICH IS ON MANY OF THEIR VEHICLES. FAILURE OF THIS PART CAUSES VEHICLE TO BOUNCE EXCESSIVELY WHICH MAKES THE VEHICLE MORE DIFFICULT TO CONTROL.

DRIVER SIDE REAR TAIL/BRAKE LIGHT GOES OUT WHEN OPEN AND CLOSE REAR HATCH. PASSENGER SIDE REAR HAS SAME ISSUE WHICH WAS RECALLED AND REPAIRED. TAP THE REAR QUARTER PANEL OR HIT A BUMP TAIL LIGHT WILL TURN OFF OR ON.

WHILE DRIVING, MY A/C CLIMATE CONTROL HAS FAILED IN 2017 GMC YUKON (MILAGE 78,734). THIS HAS CAUSED A DANGEROUS PROBLEM WHEN THE WINDSHIELD FOGGED UP AND I COULDN'T SEE OUT THE WINDSHIELD ALMOST CAUSING A CRASH. I WAS SCARED TO DEATH FROM THIS INCIDENT DRIVING ON I270 HERE IN MD. I AM BOTH SHOCKED AND APPALLED THERE IS NO RECALL ISSUED AND THAT GM USED LEAKY AIR CONDITIONERS THAT BUCKLE UNDER PRESSURE IN MANY 2014-2017 TRUCKS AND SUVS. WHETHER IT'S BUSTED HOSES OR LEAKY CONDENSORS, THOUSANDS OF GM OWNERS LIKE ME ARE UPSET THAT A NATIONWIDE RECALL HAS NOT BEEN ISSUED TO REPAIR THIS DANGEROUS PROBLEM. IT'S SUCH A WIDESPREAD PROBLEM THAT THERE'S A NATIONWIDE BACKORDER FOR REPLACEMENT PARTS. MANY OF THE ORIGINAL REPLACEMENT PARTS WERE DISCONTINUED TO TO THE DEFECT. SEE TSB PIE0340. ALONG WITH THE ALLEGED PROBLEMS WITH THE COMPRESSOR TO CONDENSER LINES, A CLASS ACTION LAWSUIT SAYS THE AIR CONDITIONER CONDENSERS ARE DEFECTIVE BECAUSE THE MATERIALS USED TO MANUFACTURE THE CONDENSERS ARE DEFECTIVE. I TOOK IT TO MY LOCAL SHOP TO FIND OUT MY CONDENSER NEEDS REPLACING AND THE SERVICE TECH TOLD ME IT IS NOT UNDER WARRANTY BUT HAVE HAD MANY PROBLEMS WITH THE CONDENSER ON THIS MAKE AND MODEL VEHICLE . HE ALSO AGREED WITH ME THAT IT SHOULD BE A RECALL SINCE THERE HAVE BEEN SO MANY VEHICLE WITH THE SAME PROBLEM. MY DEALER WANTS TO CHARGE ME $160 JUST TO DIAGNOSE THIS PROBLEM, ALTHOUGH THE DEALER ACKNOWLEDGED THIS PROBLEM FIRST NOTED IN BULLETIN # PIE0340 DATE: JUL 2015. THEN THEY ESTIMATE REPLACEMENT OF DEFECTIVE PARTS TO BE $2000!! I CALLED GMC CUSTOMER SERVICE CASE # 9-6360482931 I ASKED WHY I WAS NEVER NOTIFIED OF THIS PROBLEM WHEN I BOUGHT THIS USED VEHICLE AND THEY DECLINED TO ANSWER. I WOULD NOT HAVE PURCHASED THIS VEHICLE HAD I HAVE KNOWN OF THIS SAFETY DEFECT. I RESPECTFULLY ASK THAT YOU HAVE GM ISSUE A RECALL.

DEFECTIVE RADIATOR LEAKS R1234 FREON.

VEHICLE HAS HARD SHIFT FROM PARK. MOST OFTEN WHEN FIRST DRIVEN OF THE DAY BUT ALSO OCCURS WHEN STOPPING FOR REDLIGHTS OR STOP SIGNS WHILE TRAVELING.

WHILE PULLING INTO A PARKING SPACE, THE BRAKES SHUTTERED AND THEY WOULDN'T HARDLY WORK. ALMOST COULDN'T GET THE VEHICLE STOPPED. A WARNING ON MY DASH SAID "SERVICE BRAKE ASSIST." THERE WAS A RECALL ISSUED IN CANADA BUT NON HERE FOR MY VEHICLE SO FAR. THIS IS A DANGEROUS SAFETY HAZARD THAT NEEDS TO BE FIXED. GMC NEEDS TO ESTABLISH A RECALL AS SOON AS POSSIBLE.

AFTER SENDING MY SUV FOR THE BRAKE RECALL(THE BRAKES ACTUALLY FAILED WHILE I WAS DRIVING) LAST MONTH, MY BRAKES FAILED AGAIN WHILE DRIVING OUT OF MY DRIVEWAY, ON WEDNESDAY 8/19 -ON MY WAY TO WORK.. I DROVE STRAIGHT TO THE DEALERSHIP. BASICALLY HAVING TO HARD PUSH THE BRAKES ON CITY STREETS STOP LIGHTS ETC. SCARY. YESTERDAY, 8/20 THEY TOLD ME THE CAR WAS FIXED. ON MY WAY TO THE DEALERSHIP 30 MIN AWAY, THEY TELL ME AFTER DRIVING THE VEHICLE, THAT BRAKE INDICATION CAME ON THE SCREEN AND THEY WILL NEED TO KEEP IT FOR MY SAFETY. AS OF NOW NO WORD ON IT BEING CORRECTED, AND QUITE HONESTLY NOT FEELING SAFE ABOUT DIVING THE CAR.

CHECK ENGINE LIGHT CAME ON AND FLASHING, STABILITRACK LIGHT COMES ON, VEHICLE IDLES ROUGH AND EVENTUALLY STALLED OUT. THIS HAS HAPPENED TO ME TWICE IN MY 2017 GMC YUKON. ONCE AT ~53K MILES, AGAIN AT ~64K MILES. ONE TIME IT STALLED ON THE SIDE OF THE ROAD WITH MY KIDS IN THE VEHICLE WITH ME LATE AT NIGHT ON VACATION AND HAD TO BE TOWED IN THE MIDDLE OF THE NIGHT AND WE HAD TO STAY IN A HOTEL OUT OF TOWN UNEXPECTEDLY. THE 2ND TIME HAPPENED CLOSER TO HOME BUT HAD TO PAY FOR A RENTAL CAR SINCE THIS IS MY ONLY VEHICLE AND THE DEALERSHIP NO LONGER DOES LOANERS. THE VEHICLE RUNS ROUGH WHILE DRIVING, LOSES POWER, AND SEEMS TO LOSE CONTROL. IT IS VERY SCARY WHEN IT HAPPENS. HAPPENED IN OCT 2019 AND AGAIN JULY 2020. IT IS THE SAME ISSUE AS DESCRIBED IN N182198000 SPECIAL COVERAGE MEMO (DCS5097) FROM JULY 26, 2019 BUT ISN'T COVERED IN MY STATE YET APPARENTLY.

MY DRIVERS SIDE BRAKE LIGHTS RARELY COME ON. IF I HIT A BUMP THEY COME ON FOR A SECOND.

IN THE LAST YEAR, BOTH OF THE REAR TAIL LIGHTS HAVE FAILED IN MY 2017 GMC YUKON. TO HAVE THE DEALERSHIP REPLACE THE TAIL LIGHTS IT COST +$750 PER TAIL LIGHT FOR A CAR THAT IS ONLY 3 YEARS OLD. I WORK WITH LED LIGHTING AND ON AVERAGE, LED LIGHTS SHOULD LAST FOR 5000 HOURS OF USE. THERE IS NO WAY THAT IN THE LAST 3 YEARS WE HAVE UTILIZED 5000 HOURS OF DRIVE TIME TO WARRANT THAT THESE LED'S SHOULD BE BURNING OUT. I BELIEVE THAT THE LED'S THAT THEY ARE USING ARE DEFECTIVE AND A CASE NEEDS TO BE MADE TO SEE IF GMC IS HAVING ISSUES WITH THE REAR TAIL LIGHT LED'S, THE PARTS ARE WAY TOO EXPENSIVE TO BE FAILING AFTER A FEW YEARS OF INTERMITTENT USE. *TR

VEHICLE HAS A ROUGH IDLE AT COLD START. ALSO MISFIRES AT STOPLIGHTS AND RANDOM TIMES. VEHICLE STALLED ONCE THIS MORNING COMPLETELY. TOLD BY MY GMC DEALERSHIP THIS IS A COMMON PROBLEM AND I WOULD HAVE TO REPLACE ALL FUEL INJECTORS FOR OVER $2,000. I JUST PURCHASED THIS VEHICLE IN MARCH. THE FUEL INJECTORS ARE ON BACK-ORDER CURRENTLY SO I AM UNABLE TO HAVE IT REPAIRED. I WAS TOLD ANOTHER VEHICLE LIKE MINE AT THAT SERVICE CENTER HAS BEEN WAITING ALREADY FOR 6 WEEKS FOR FUEL INJECTORS AND THAT I WOULD HAVE TO WAIT AT LEAST ANOTHER MONTH. THIS MEANS I WILL NOT BE ABLE TO REGISTER MY VEHICLE WITH MY STATE AS IT WILL NOT PASS SMOG INSPECTION WITH A CHECK ENGINE LIGHT. I HAVE BEEN UNABLE TO REGISTER IT DUE TO THE DMV CLOSURE FROM COVID-19. ITS VERY DANGEROUS TO DRIVE A VEHICLE THAT CAN STALL AT ANY MOMENT AND IS IMPOSSIBLE TO FIX WITHOUT WAITING FOR PARTS. THESE PARTS ARE OBVIOUSLY ON BACK-ORDER SO LONG BECAUSE THIS IS A WIDESPREAD PROBLEM. I FOUND A SERVICE BULLETIN FROM NHTSA ( DCS5097 ) WHICH COVERS MY PROBLEM EXACTLY. BUT FOR SOME UNKNOWN REASON, SPECIAL COVERAGE ONLY APPLIES TO 13 STATES. I BELIEVE THIS IS A MUCH MORE WIDESPREAD PROBLEM THAN THOUGHT AND I BELIEVE MY SAFETY AND THE SAFETY OF THOSE AROUND ME IS AT RISK IF I DRIVE THIS VEHICLE. MY VEHICLE AND THOSE LIKE MINE SHOULD BE COVERED BY SPECIAL COVERAGE AS WELL. AND AT THE VERY LEAST THE PARTS TO FIX THIS SHOULD BE AVAILABLE GIVEN THAT ITS BEEN A KNOWN ISSUE NOW FOR WELL OVER A YEAR. THESE PARTS HAVE BEEN BACK-ORDERED WAY BEFORE COVID-19 EVEN HIT, SO IT CANNOT BE ATTRIBUTED TO THAT. GM HAS AN OBLIGATION TO KEEP THEIR VEHICLES ON THE ROAD SAFE AND MAINTAINED TO THE BEST OF THEIR ABILITY AND WHEN IT COMES TO THIS ISSUE THEY ARE FAILING TO DO SO. *TR

INTERMITTENTLY DEFECTIVE TAIL / BRAKE LIGHT. LED CIRCUIT BREAKS. KNOWN ISSUE. DEALER WANTS $800 TO FIX.. *TR

LEAK IN CONDENSER, SAME AS RECALL 17336 AIR CONDITIONING CONDENSER REFRIGERANT LEAK FOR GMC YUKON MODEL YEAR 2015 TO 2017. MY VEHICLE VIN DOES NOT FIT RECALL. *TR

TL* THE CONTACT OWNS A 2017 GMC YUKON. THE CONTACT STATED THAT THE DRIVER'S SIDE REAR TAIL LAMPS WERE INOPERABLE. THE VEHICLE WAS TAKEN TO MANDAL BUICK GMC (11290 MANDAL PKWY, D'IBERVILLE, MS 39540). THE CONTACT WAS INFORMED THAT THE VEHICLE WAS NOT INCLUDED IN A RECALL AND ADDITIONALLY, THE VEHICLE WARRANTY WAS EXPIRED. THE DEALER QUOTED A COST OF $760 TO HAVE THE VEHICLE REPAIRED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT INFORMED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 58,000.

WITHOUT WARNING, RIGHT REAR TAILLIGHT STOPS WORKING. THIS IS FOR OPERATING AND STOPPING. APPARENTLY, THERE ARE MANY COMPLAINTS OF THIS...SEVERE SAFETY HAZARD FOR A KNOWN PART WITH PROBLEMS.

THE REAR TAIL-GATE HAS COME DOWN BY ITSELF WHEN PUTTING ITEMS INTO OR TAKING ITEMS OUT OF THE BACK OF THE CAR. IT HAS HAPPENED AT LEAST SIX TIMES AND WITHOUT WARNING. IT HAS HAPPENED IN OUR DRIVEWAY AND IN PARKING LOTS. VEHICLE WAS PARKED AND TURNED OFF AT THE TIME. THIS CAN HURT OR KILL AN ADULT OR CHILD. I'M GOING TO REPORT THIS TO THE DEALER AT THE NEXT SERVICE VISIT, BUT I ALSO WANTED TO REPORT IT HERE BECAUSE YOU ARE THE IN CHARGE OF THE PUBLICS SAFETY. THERE IS ANOTHER INDIVIDUAL THAT HAS REPORTED THIS SAME PROBLEM. THANK YOU!

BEGINNING AROUND 56,000 MILES THE TRANSMISSION STARTED LURCHING AND STUTTERING AT SLOW SPEEDS. IT IS WORSE WHEN COLD BUT NEVER QUITE GOES AWAY. DEALERSHIP KEPT IT FOR 3 DAYS AND FELT IT BUT SAID ALL WAS WITHIN NORMAL RANGE. BEGINNING AROUND 65,000 IT STARTED STUTTERING WHEN TRYING TO ACCELERATE WHILE IN MOTION, SUCH AS ON THE HIGHWAY WHEN TRYING TO PASS. THIS IS NOT ONLY ANNOYING BUT DANGEROUS WHEN YOU CAN'T GET THE POWER YOU NEED WHEN NEEDED BECAUSE THE TRANSMISSION CAN'T DECIDE WHEN TO SHIFT.

TL* THE CONTACT OWNS A 2017 GMC YUKON. THE CONTACT RECEIVED THREE DIFFERENT LETTERS FROM THE MANUFACTURER. THE LETTER SENT IN APRIL OF 2019 STATED THAT THEY WERE EXTENDING THE WARRANTY COVERAGE. THE LETTER SENT IN SEPTEMBER OF 2019 MENTIONED NHTSA CAMPAIGN NUMBER: 19V645000 (SERVICE BRAKES, HYDRAULIC). THE THIRD LETTER SENT IN NOVEMBER OF 2019 INDICATED THAT THE ISSUE WAS NOT A RECALL AND THEY WERE EXTENDING THE WARRANTY AGAIN. THE VEHICLE WAS TAKEN TO WINEGARDNER GMC BUICK OF PRINCE FREDERICK (935 SOLOMONS ISLAND RD N, PRINCE FREDERICK, MD 20678, (443) 295-6182) WHERE THE EBCM MODULE WAS REPROGRAMMED ONLY FOR THE HYDRAULIC SYSTEM. THE VACUUM PUMP SYSTEM WAS NOT REPAIRED. THE MANUFACTURER WAS CONTACTED, BUT HAD NOT RESPONDED BACK TO THE CONTACT'S INQUIRIES. THE CONTACT HAD NOT EXPERIENCED A FAILURE.

TL* THE CONTACT OWNS A 2017 GMC YUKON. WHILE ATTEMPTING TO PULL OUT INTO TRAFFIC, THE TRANSMISSION SUDDENLY SLIPPED AND THE VEHICLE MADE A HIGH PITCHED HUMMING SOUND. THE CONTACT TOOK THE VEHICLE TO HILTON HEAD BUICK GMC CADILLAC (LOCATED AT 1090 FORDING ISLAND RD, BLUFFTON, SC 29910, 843-815-1500) WHERE IT WAS DIAGNOSED THAT THE TORQUE CONVERTER NEEDED TO BE REPLACED. THE VEHICLE HAD NOT BEEN REPAIRED BECAUSE THE DEALER WAS UNABLE TO GET THE PART FROM THE MANUFACTURER. THE DEALER WAS UNABLE TO GET CONFIRMATION AS TO WHEN THE PART WOULD BE PROVIDED. THE CONTACT ATTEMPTED TO CALL THE MANUFACTURER, BUT WAS UNABLE TO SPEAK WITH ANYONE. THE APPROXIMATE FAILURE MILEAGE WAS 96,700.

TL* THE CONTACT OWNS A 2017 GMC YUKON. WHILE DRIVING VARIOUS SPEEDS, THE CONTACT HEARD AN ABNORMAL RUBBING NOISE COMING FROM THE FRONT DRIVER'S SIDE WHEEL. ALSO, THE STEERING WHEEL SHOOK WITHOUT WARNING. THE VEHICLE WAS TAKEN TO THOMPSON BUICK GMC (2600 WAKE FOREST RD, RALEIGH, NC 27609, (919) 809-6217) TO BE DIAGNOSED, BUT THE FAILURES COULD NOT BE DUPLICATED. THE VEHICLE WAS REPAIRED; HOWEVER, THE FAILURES RECURRED MULTIPLE TIMES. THE CONTACT REFERENCED BULLETIN NUMBER: 00-03-10-006N. THE MANUFACTURER WAS MADE AWARE OF THE FAILURES AND PROVIDED CASE NUMBER: 9-5435571823. NO FURTHER ASSISTANCE WAS PROVIDED. THE FAILURE MILEAGE WAS APPROXIMATELY 28,000.

PASSENGER SIDE BRAKE AND TAIL LIGHT QUIT WORKING TOOK TO DEALERSHIP FOR REPAIR. DEALERSHIP SAID THEY HAD FIXED IT AND HAD NOT. TOOK BACK TO THEM AND THEY SAY THEY CAN'T GET ONE IT'S ON BACK ORDER. AFTER LOOKING INTO IT MYSELF IT SEEMS TO BE A VERY COMMON PROBLEM THAT GM ISN'T DOING ANYTHING TO FIX BUT PUT THE SAME LIGHTS BACK IN THAT WILL FAIL AGAIN. I'VE ASKED ABOUT AN UPDATED LIGHT THAT WOULDN'T FAIL AGAIN AND THE DEALERSHIP SEEMS TO HAVE NO KNOWLEDGE ABOUT THE LIGHTS AT ALL. GM NEEDS TO STEP UP AND FIX THE THIS ISSUE AS IT IS A SAFETY PROBLEM.

FROM TIME TO TIME THE VEHICLE LUNGES FORWARD WHEN IM STOPPED AT A STOP SIGN, CROSSWALK OR A STOP SIGN. I HAVE HAD IT INTO THE DEALERSHIPS NUMEROUS TIMES BUT GM ONLY WANTS TO PUT BANDAIDS ON THE ISSUE, GM HAS A MAJOR ISSUE WITH THEIR EIGHT SPEED TRANSMISSION, THEY ONLY HAVE INTERNAL BULLETINS TO THEIR DEALERSHIPS. THE DEALERSHIP TELLS YOU TO BRING THE VEHICLE IN AND THEY WILL DRIVE IT WITH THE CUSTOMER, BUT THE ISSUE IS INTERMITTENT AND DOESNT ALWAYS LUNGES, GM IS TRYING TO OUTLAST THE CUSTOMERS HOPING THEY WILL GET TIRED OF DEALING WITH THE ISSUE AND THEY WILL GO AWAY. GM CANNOT AFFORD A RECALL BECAUSE OF THE SIZE OF THE PROBLEM, SEVERAL DEATHS WILL OCCUR UNTIL THIS ISSUE IS RESOLVED. THE ISSUE HAPPENS ON THE ROADWAYS

WAS IN SCHOOL CAR LINE, WENT TO MOVE FORWARD A LITTLE AND BRAKES DIDNT WORK PROPERLY. ALMOST HIT THE CAR IN FRONT OF ME. GO STRAIGHT TO A DEALERSHIP WHERE THEY TELL ME ABOUT THE RECALL. SCHEDULE THE FIX, THIS MORNING WHEN I LEFT THE DEALERSHIP I DISCOVER THE RECALL DIDNT FIX MY ISSUE. LEARN THAT I NEED A VACCUUM PUMP REPLACEMENT. I AM UPSET THAT I AM SUPPOSE TO PAY $500 FOR A FAULTY VACCUUM PUMP AND RISK MY LIFE, THE KIDS LIVES AND PEOPLE'S LIVE AROUND ME UNTIL I CAN AFFORD THIS REPAIR WHEN IT IS FAULTY IN THE FIRST PLACE.

TL* THE CONTACT OWNS A 2017 GMC YUKON. WHILE THE CONTACT'S HUSBAND WAS PARKING THE VEHICLE, THE BRAKE PEDAL HAD TO BE DEPRESSED TO THE FLOORBOARD TO MAKE A COMPLETE STOP. ALSO, THE SERVICE BRAKE ASSIST WARNING INDICATOR ILLUMINATED. THE VEHICLE WAS TAKEN TO BLAKE FULENWIDER DODGE (LOCATED AT 1310 E MAIN ST, EASTLAND, TX 76448, (254) 488-429) WHERE IT WAS SERVICED PER NHTSA CAMPAIGN NUMBER: 19V645000 (SERVICE BRAKES, HYDRAULIC) ON OCTOBER 18, 2019. AFTER THE CONTACT LEFT THE DEALER, AND WHILE DEPRESSING THE BRAKE PEDAL, THE CONTACT HEARD AN ABNORMAL NOISE COMING FROM THE BRAKES AND THE VEHICLE JERKED FORWARD. THE MANUFACTURER WAS NOT NOTIFIED. THE FAILURE MILEAGE WAS 50,700. THE VIN WAS NOT AVAILABLE.

DRIVERS SIDE LED BRAKE LIGHT DOES NOT FUNCTION. VEHICLE HAS 52,000 MILES. KNOWN DEFECT YET GMC DOES NOT OFFER REPAIR. REQUIRES $800 LIGHT ASSEMBLY REPLACEMENT.

THE GMC YUKON MODELS IN ALL TRIMS, HAVE FAULTY LED STRIPS THAT CAUSE THE BRAKE LIGHTS TO FAIL ON THE LEFT, AND RIGHT BRAKE LIGHT ASSEMBLY. THE FRUSTRATING PART IS IT WORKS INTERMITTENTLY, AND WHEN IT'S OFF A SLIGHT TAP WILL MOMENTARILY BRING IT BACK ON FOR THE DURATION OF THE JOLT. THIS LEADS ME TO BELIEVE THAT IT'S FAULTY CONNECTION INSIDE THE SEALS BRAKE LIGHT ASSEMBLY. THERE ARE THOUSANDS OF COMPLAINTS ONLINE ON OWNER FORUMS OF GMC YUKON'S . THIS IS KNOWN AS THE NEW YEAR MODELS 18-19 ARE NOT HAVING THE SAME ISSUE.

TL* THE CONTACT OWNS A 2017 GMC YUKON. WHILE DRIVING 14 MPH, THE BRAKE PEDAL WAS DEPRESSED, BUT THE VEHICLE FAILED TO STOP AND THE BRAKE ASSIST AND CHECK ENGINE WARNING INDICATORS ILLUMINATED. AS A RESULT, THE CONTACT CRASHED INTO ANOTHER VEHICLE. THE AIR BAGS DID NOT DEPLOY. A POLICE REPORT WAS NOT FILED AND THERE WERE NO INJURIES. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHO STATED THAT A MODE FOR THE BRAKES WAS SWITCHED. THE VEHICLE WAS REPAIRED. THE VEHICLE WAS NOT TAKEN TO A DEALER FOR DIAGNOSTIC TESTING OR REPAIRS. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 27,698.

DRIVERS SIDE LED BRAKE LIGHT STRIP INOP. DEALER SAYS ITS 650 PER SIDE PLUS LABOR TO REPLACE. GMC IS AWARE OF ISSUE BUT WILL NOT STAND BEHIND THERE PRODUCT. THEY ALSO LIE AND SAY IT'S THE FIRST THEY HAVE HEARD OF THIS TYPE OF FAILURE. THIS IS A SAFETY CONCERN AND CUSTOMER IS LIABLE FOR A TICKET THAT MAY RESULT FROM FAULTY GM PARTS.

WHILE DRIVING AT SLOW SPEEDS THE TRANSMISSION WILL SUDDENLY SHIFT EXTREMELY HARD INTO FIRST GEAR WHEN WHILE LIGHTLY INCREASING SPEED. THE TRANSMISSION WILL SHIFT EXTREMELY HARD INTO FIRST GEAR WHILE GRADUALLY COMING TO A STOP. OCCASIONALLY WHILE DRIVING SLOWLY (PARKING LOTS) THE TRANSMISSION UPSHIFTS TO SECOND GEAR CAUSING THE CAR TO LURCH FORWARD NEARLY CAUSING A COLLISION. THIS IS A CONTINUING PROBLEM THAT CANNOT BE REPAIRED AT THE DEALERSHIP.

I PURCHASED MY 2017 YUKON DENALI IN 2017. SINCE THE DAY I BOUGHT IT I HAVE NOTICED A PROBLEM WITH APPEARS TO BE THE TRANSMISSION. I WILL BE AT A STOP THEN I ACCELERATE AND THE CAR HAS A HARD SHIFT FORWARD. IT TENDS TO PULL FORWARD ALL OF A SUDDEN BUT VERY VIOLENTLY. I HAVE TAKEN IN MY YUKON TO THE TWO GMC DELERSHIPS IN MY AREA SEVERAL TIMES. THEY HAVE SERVICED IT AND EVEN PERFORMED A TRANSMISSION FLUSH BUT STILL THE PROBLEM HAS ALWAYS CONTINUED. I HAVE BEEN DEALING WITH THIS YUKON PROBLEM FOR TWO YEARS NOW. ITS SO DANGEROUS TO DRIVE.

I HAVE TAKEN IT IN TO THE DEALERSHIP SEVERAL TIME FOR INSPECTION. THE FIRST TIME INVOLVED A REPEATED VIBRATION WHILE DRIVING. THE RESOLUTION WAS TO CHANGE OR FLUSH THE TRANSMISSION FLUID TO GET RID OF ANY METAL SHAVINGS. SINCE THEN I'VE TAKEN IT BACK INTO THE DEALERSHIP TWICE WITH REPORTS OF JERKING, A DELAYED START WHEN ACCELERATING, AND MOST RECENTLY A LURCHING WHEN SHIFTING BETWEEN REVERSE AND DRIVE. EACH TIME THEY HAVE SAID THIS IS NORMAL.

REAR PASSENGER TAIL LIGHT FAILURE. TAIL LIGHT FAILS PREMATURELY WITHOUT ANY MEANS TO WARN DRIVER SHORT OF DIRECT OBSERVATION. PROBLEM KNOWN TO GMC GIVEN HIGH NUMBER OF FAILURES AND COMPLAINTS OF PREMATURE FAILURES. TAIL LIGHT IS EXPENSIVE TO REPLACE.

TAIL LIGHTS INTERMITTENTLY WORK. DEALER CLAIMS FULL TAIL LIGHT ASSEMBLY REQUIRED TO FIX (AT ~$850) AND NOT COVERED BY ANY WARRANTY. HUNDREDS OF COMPLAINTS ONLINE OF SIMILAR PROBLEM. SAFETY CONCERN BECAUSE PROBLEM IS INTERMITTENT. INDEPENDENT REPAIR SHOPS POST FIXES TO SOLUTION BY MELTING PLASTIC HOUSING AND CONNECTING METAL PIECES ON CIRCUIT BOARD ASSEMBLY THAT BREAK (THIS IS JUST A THIN METAL PLATE THAT WAS POORLY DESIGNED AND CRACKS AT A SIMILAR POINT FREQUENTLY. I THINK THIS IS A FAULTY DESIGN THAT EXPOSES MANY CUSTOMER ERA TO GREAT RISK AND SHOULD BE COVERED BY GMC. PLEASE LOOK INTO IT. CAR IS IN MOTION, STATIONARY OR TURNING WHEN HAPPENS. BRAKE LIGHTS ARE LIGHT THAT IS IMPACTED.

WHEN DRIVING OCCASIONALLY YOU HAVE TO PUSH REALLY HARD ON THE BRAKES TO STOP. 9/10 TIMES BRAKES WORK NORMAL BUT ONCE IN A WHILE YOU HAVE TO PRESS VERY HARD TO STOP. WAS PULLING INTO MY DRIVEWAY AT A VERY LOW SPEED BRAKES WERE HARD TO PRESS AND RAN INTO THE WALL OF THE GARAGE. BROUGHT TO THE DEALER NUMEROUS TIMES SINCE I BOUGHT IT BRAND NEW AND STILL NOT FIXED.

THE REAR PASSENGER LIGHT ASSEMBLY HAS FAILED. NO LIGHTS WITHIN THE HOUSING ARE CURRENTLY WORKING. THE UNSAFE CONDITION EXISTS WHEN THE VEHICLE IS IN MOTION, AS IT HAS NO RUNNING LIGHTS, BRAKE LIGHTS OR TURN SIGNALS. THIS APPEARS TO BE A VERY COMMON PROBLEM FOR YUKON'S OF THIS YEAR, WHICH ARE STILL FAIRLY NEW.

DRIVING FROM PRESCOTT, AZ TO PHOENIX, AZ WITH MY HUSBAND AND 3 YEAR OLD SON. WE WERE HEADING EAST ON SR-69 WHEN WE WERE PULLED OVER. WE WERE INFORMED THAT OUR PASSENGER SIDE BRAKE LIGHT WAS NON-OPERATIONAL. AFTER INSPECTION IT WAS FOUND THAT TURN SIGNAL AND HAZARD LIGHTS WORKED BUT NOT BREAK. A REPAIR ORDER WAS ISSUED. WE TOOK IT TO THE GMC DEALERSHIP AND WAS TOLD THE WHOLE TAIL/BRAKE LIGHT HOUSING, WIRE, AND POTENTIALLY THE FUSE NEEDED REPLACED AND THAT IT WOULD COST $700. WE WERE ALSO TOLD BY THE DEALERSHIP THAT A THEY HAVE HAD SEVERAL GMC YUKON OWNERS COME IN WITH THE SAME ISSUE AND THAT IT WAS A PART MALFUNCTION THAT MAY OR MAY NOT BE COVERED BY OUT WARRANTY.

LOW SPEED BREAK FAILURE. IN MY DRIVEWAY, IN PARKINGLOTS, USUALLY AFTER HAVING FOOT ON BREAK TO "ROLL" AND THEN STOP AGAIN, NO BREAKS, OR HAVE TO PUT TWO FEET DOWN TO STOP. I HIT A CAR IN FRONT OF ME TWO DAYS AGO AFTER WAITING AT A RED LIGHT, STARTING TO ROLL BECAUSE THEY ROLLED, THEN THEY STOPPED, AND I HIT THE BREAK AND NOTHING HAPPENED. MY HUSBAND HAS TAKEN THE CAR MULTIPLE TIMES TO BE LOOKED AT FOR THE BREAKS NOT WORKING FOR AT LEAST 6 MONTHS.

2017 YUKON (ONLY BEEN IN USE FOR 19 MONTHS) DS BRAKELIGHT ASSEMBLY (RED LED OUTTER RING) STOPPED WORKING.

HAVE NO BRAKES AT LOW SPEED DUE TO FAULTY VACUUM PUMP

PULLED OVER BY POLICE FOR MALFUNCTIONING LHR BRAKE LIGHT. ENTIRE REAR LAMP ASSEMBLY MUST BE REPLACED SINCE IT IS AN INTEGRATED CIRCUIT BOARD WITH LED LAMPS. $700 PLUS INSTALLATION. SEVERAL VICTIMS ON-LINE DISCUSSION FORUMS.

THE TRANSMISSION OR TORQUE CONVERTER ARE SHUDDERING HOW DO WE FIX, HOW DO I PROTECT FAMILY, WILL THE TRANSMISSION FALL OUT ON HIGHWAY CAN I KEEP DRIVING AND BE SAFETY WITH FAMILY?

MY HUSBAND AND I WERE DRIVING ON THE HIGHWAY AT 70 MPH WHEN HE NEEDED TO SLOW DOWN AND NOTICED THE BRAKES ON THE YUKON WERE NOT FUNCTIONING PROPERLY. MORE SPECIFICALLY, THE BRAKES WOULD NOT FUNCTION THE FIRST 3-4 TIMES WHEN THEY WERE APPLIED OR TAPPED, BUT THEREAFTER THE BRAKES WOULD BECOME HARD AND HE HAD TO DEPRESS THE BRAKE PEDAL AS HARD AS HE COULD BUT WITH LITTLE TO NO STOPPING ABILITY. THE 'BRAKE ASSIST' LIGHT CAME ON. HAD WE BEEN IN ANY TRAFFIC OR ON A SHORTER ROAD, WE WOULD HAVE SURELY CRASHED INTO SOMEONE AND IT COULD HAVE BEEN CATASTROPHIC CONSIDERING WE LIVE IN DALLAS WHERE THERE IS A LOT OF TRAFFIC. THIS DAY WE WERE VERY LUCKY! GM HAD ISSUED A SERVICE BULLETIN #PIT5361B WHICH AFFECTED MULTIPLE YEARS AND CLASSES OF VEHICLES TO INCLUDE THE 2015 YUKON. GM ACKNOWLEDGED THAT 'A CUSTOMER MAY COMMENT ON A HARD BRAKE PEDAL OR THAT INCREASED EFFORT IS NEEDED TO DEPRESS THE BRAKE PEDAL.' AS EVIDENCE OF THE DEFECT, GM NOTIFIED ITS DEALERS, 'WHILE PERFORMING NORMAL DIAGNOSTICS, FLUID MAY BE FOUND IN THE BRAKE BOOSTER AND/OR THE BOOSTER VACUUM LINE.' HOWEVER, WE CALLED MULTIPLE DEALERSHIPS WITHIN THE DFW AREA AND THEY ALL DENIED KNOWING ANY ISSUE WITH GM BRAKES FAILING OR THE VACUUM PUMP. INTERESTINGLY, THERE IS A CLASS ACTION LAWSUIT ON THIS VERY ISSUE AND GM ALSO ISSUED A SERIES OF SERVICE BULLETINS TO ITS DEALERS REGARDING THE BRAKE DEFECT, WITH THE LATEST BULLETIN DATED MARCH 15, 2017, TO INCLUDE THE 2015-2016 YUKON. OURS IS JUST A 2017, 1 YEAR OUTSIDE OF THAT. WHO IS TO SAY THIS YEAR ISN'T AFFECTED CONSIDERING PAST HISTORY OF THE BULLETINS. IT WAS THANKSGIVING HOLIDAY AND NO DEALERSHIP COULD EVEN GET TO IT BESIDES NOT KNOWING OF ANY 'ISSUE', EVEN THOUGH IT'S ALL OVER THE INTERNET.

WHILE COMING TO TRAFFIC LIGHTS TO MAKE A STOP THE VEHICLE'S BRAKE PEDAL BEGINS TO GET HARDER AND HARDER TO PRESS WHILE LOSING THE ABILITY TO STOP THE VEHICLE. WHILE ENTERING PARKING SPACES THE BRAKE PEDAL WILL GET EXTREMELY HARD AND LOSE ALMOST ALL STOPPING POWER. THIS HAPPENED A NUMBER OF TIMES IN ONE DAY RESULTING IN A NEAR REAR-ENDING OF ANOTHER VEHICLE AS WELL AS HITTING A CURB WHICH STOPPED US FROM ENTERING THE FRONT WINDOW OF A RETAIL ESTABLISHMENT.

I HAVE 47,078 MILES ON THIS VEHICLE. IT CURRENTLY HAS A RANDOM MISFIRE THAT IS BEING BLAMED ON BAD FUEL INJECTORS. TO REPLACE ALL OF MY FUEL INJECTORS WILL COST ME APPROXIMATELY $1783.00 AT MY LOCAL DEALERSHIP AS MY VEHICLE IS 10,000 MILES OVER WARRANTY. I SHOULDN'T HAVE TO BE REPLACING FUEL INJECTORS ON A 1 YEAR OLD VEHICLE. IT RUNS ON LIMITED POWER MODE WHEN I START IT. I HAVE TO START IT AND THEN SHUT IT OFF AGAIN FOR IT TO RUN IN NORMAL OPERATION BUT IT STILL SHOWS A MISFIRE CODE.

THE VEHICLE SEEMS TO OCCASIONALLY STALL/SPUTTER WHEN ACCELERATING/PROCEEDING FROM A STOP POSITION AT A LIGHT OR STOP SIGN. EVEN THOUGH ON A SMOOTH ROAD SURFACE, THE RIGHT WHEEL SEEMS TO VIBRATE. THE ENGINE STALL IS THE SAME INSTANCE WHICH OCCURRED IN THE 2015 VEHICLE THAT I TRADED BECAUSE IT LEFT ME STRANDED. THE WHEEL SHAKING IS NOT A CONTINUOUS EVENT. THE STALLING OCCURS FREQUENTLY. AN APPOINTMENT HAS BEEN SCHEDULED FOR MONDAY 8/13 FOR A DEALER INSPECTION OF MY COMPLAINT. VEHICLE WILL BE LEFT OVER AND A LOANER PROVIDED.

MAY 17, 2018 CHECK ENGINE LIGHT CAME ON WHILE DRIVING. DEALERSHIP SAID INJECTOR #3 WAS BAD. REPLACED SAME DAY. THEN CHECK ENGINE LIGHT CAME ON AGAIN WHILE DRIVING ON 6/13/18. DEALERSHIP SAID INJECTOR #6 IS BAD. IN PROGRESS OF REPLACING IT. THIS IS A NEW VEHICLE WITH 13,000 MILES ON IT CURRENTLY. BOUGHT THE VEHICLE NEW FROM THE DEALERSHIP SEP 30TH, 2017. TWO BAD INJECTORS IN 9 MONTHS WITH THE OCCURRENCES HAPPENING WITHIN LESS THAN A MONTH OF EACH OTHER? SOMETHING HAS TO BE CAUSING THE INJECTORS TO GO BAD.

TRANSMISSION SHIFTS ARE VERY ROUGH IN SLOW TRAFFIC WITH AS MUCH AS ONE TO TWO SECOND DELAYS IN SHIFTING INTO GEAR WITH A LOUD THUMP. IT IS SO ROUGH THAT IT FEELS LIKE SOMEONE MAY HAVE RAN INTO THE YOUR BACK BUMPER. IT IS ALSO BAD ENOUGH THAT IT STARTLES THE DRIVER AND COULD BE A SAFETY ISSUE. GM IS SAYING THAT THIS IS NORMAL FOR THIS EIGHT SPEED TRANSMISSION. IF MY CAR, THE ONE I'M DRIVING NOW, HAD THIS SAME PROBLEM I WOULD DEFINITELY REPLACE THE TRANSMISSION. THIS IS A 2017 DENALI WITH LESS THAN 5000 MILES ON IT. ONLINE THERE ARE MANY COMPLAINTS ABOUT THIS AND IT SEEMS THAT GM IS TRYING TO WAIT THE PUBLIC OUT NOW THAT THE NEW VEHICLES HAVE A NEW TEN SPEED TRANSMISSION. THE DEALER TOLD ME THEY COULD NOT FIX THE PROBLEM AND WE WOULD HAVE TO LIVE WITH IT. AGAIN, THIS TO ME IS A MAJOR SAFETY ISSUE.

VEHICLE FIRE. INVESTIGATION REVEALED POINT OF ORIGIN WAS IN LEFT REAR TAIL LIGHT ASSEMBLY. CAUSE DETERMINED TO BE AN ELECTRICAL FAILURE. VEHICLE WAS STATION, HAD NOT BEEN DRIVEN AND WAS PARKED IN ATTACHED RESIDENTIAL GARAGE. FIRE DESTROYED VEHICLE AND EXTENDED TO RESIDENCE. THIS REPORT IS BEING MADE BY THE COUNTY FIRE MARSHAL. VEHICLE OWNER INFO IS JOSEPH C. LAVECCHIA, 10 LONG HILL ROAD, NEWTON NJ 07860

HANDS FREE REAR CARGO DOOR OPENS AND CLOSES WHEN PEOPLE ARE IN DANGER OF BEING STRUCK BY THE MOVING DOOR, WITHOUT AN INTENTIONAL MOTION OF THE FOOT TO OPEN OR CLOSE THE DOOR. THE DOOR HAS CLOSED ON ME SEVERAL TIMES WHILE LOADING/UNLOADING CARGO. BROUGHT TO DEALER BUT THEY SAY GMC HAS NOT RELEASED PART NUMBER OF A SOFTWARE UPDATE.

TL* THE CONTACT OWNS A 2017 GMC YUKON. WHEN THE VEHICLE WAS STARTED, THE "SAFETY ASSIST SYSTEM SERVICE" WARNING INDICATOR ILLUMINATED. THE VEHICLE WAS TAKEN TO THE DEALER (TOM KELLEY BUICK/GMC, FORT WAYNE, INDIANA) WHERE IT WAS DIAGNOSED THAT THE SENSOR FAILED AND WAS NOT COVERED UNDER WARRANTY. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND DID NOT OFFER ANY ASSISTANCE. THE FAILURE MILEAGE WAS APPROXIMATELY 900.
