Deferred Failure Risk
Vehicle-specific risks from this model-year's complaint record, known defects, and service milestones
One failed component has created stress on connected systems. Repair costs compound quickly — a $500 fix can become $3,000+ if cascade damage is ignored.
Owners of the 2018 INFINITI Q50 report engine/powertrain issues more than most other systems. Complaints concentrated in one area often signal a systemic weakness worth a targeted pre-purchase inspection.
Owners of the 2018 INFINITI Q50 report safety systems issues more than most other systems. Complaints concentrated in one area often signal a systemic weakness worth a targeted pre-purchase inspection.
Owners of the 2018 INFINITI Q50 report electrical issues more than most other systems. Complaints concentrated in one area often signal a systemic weakness worth a targeted pre-purchase inspection.
Worn chain tensioners cause timing chain skip or snap — common on GM 5.3L/6.2L, Ford EcoBoost, VW/Audi EA888, BMW N47/N63. Listen for cold-start rattles.
Water pump failure causes rapid overheating. If the engine overheats even once, head gasket damage is likely — turning a $400 part into a $3,000+ repair.
Degraded transmission fluid destroys clutch packs and solenoids. CVT transmissions are especially sensitive — neglected fluid can result in a $4,000–$8,000 replacement.
On 4WD/AWD vehicles, neglected differential or transfer case fluid causes metal-on-metal wear. Replacement costs $1,500–$4,000.
Degraded coolant loses corrosion inhibitors and attacks aluminum engine components. Can cause head gasket failure and water pump corrosion.
Worn spark plugs cause misfires that can foul and crack catalytic converters. A $150 tune-up can prevent a $1,200 catalytic converter replacement.
Dirty or failing injectors cause rough idle, reduced fuel economy, and increased emissions. Cleaning costs $100–$200; replacement $800–$1,600.

Owner Complaints
HIGH VOLUME42 safety complaints filed with NHTSA
The contact owns a 2018 Infiniti Q50. The contact stated while driving at an undisclosed speed, the air bag warning light illuminated. The vehicle was taken to the dealer, where the contact was informed that the front passenger seat and passenger seat belt needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 34,000.
The contact owns a 2018 Infiniti Q50. The contact stated that while driving at an undisclosed speed, the front passenger Occupant Classification System (OCS) sensor became inoperable. The vehicle was taken to the dealer, where it was diagnosed that the front passenger OCS sensor had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 59,200.
I am submitting this complaint regarding a safety defect in my 2018 Infiniti Q50, which was manufactured prior to May 1, 2018. Despite matching the make, model, and production timeframe associated with an existing Infiniti recall for backup camera failures, my specific vehicle is not included in the recall population. The backup camera in my vehicle intermittently fails to display an image or presents a blank or distorted screen when the vehicle is placed in reverse. This defect significantly impairs rear visibility and increases the risk of a collision, particularly in situations involving pedestrians, children, or obstacles that may not be visible through mirrors alone. The backup camera is a critical safety feature, and its failure directly compromises safe vehicle operation. The exclusion of my vehicle from the recall is concerning, given that it shares the same model year, platform, and manufacturing period as those already identified as defective. This suggests that the defect may be more widespread than currently acknowledged. A malfunctioning backup camera is not a minor inconvenience as it creates a clear and preventable safety hazard. I urge the NHTSA to review this issue and consider expanding the scope of the existing recall to include all affected 2018 Infiniti Q50 vehicles, including those manufactured before May 1, 2018, that are currently excluded. Additionally, I encourage further investigation into the consistency and reliability of the backup camera systems in this model line. This complaint is submitted not only to address my individual vehicle but also to contribute to a broader understanding of a potential safety defect that may affect other drivers. I believe that multiple reports of similar issues will help prompt appropriate action to ensure public safety. Thank you for your attention to this matter.
Odometer Fraud. The contact purchased a 2018 Infiniti Q50. It was discovered that there were three separate mileage discrepancies. The vehicle was a dealer sale. At the time of purchase, the vehicle mileage was 50,370; however, at the time of registration, it was discovered that the mileage had been rolled back from 54,000 to 28,630 miles. The mileage before the vehicle was purchased was 47,650.
Filing this complaint regarding a safety-related defect involving the turbocharger system on my 2018 INFINITI Q50. The vehicle has approximately 46,000 miles and is 8 years old. INFINITI/Nissan has acknowledged through its own Technical Service Bulletins (TSBs) that turbocharger failure on 2016–2018 Q50 3.0T vehicles is a known defect. Nissan’s documentation identifies issues such as turbo oil seal leaks, reduced engine power, smoke, and potential catastrophic engine failure, and provides an extended warranty of up to 10 years or 120,000 miles due to the safety risks associated with sudden power loss. My vehicle experienced turbocharger failure consistent with these known defects, resulting in loss of engine power, which presents a serious safety hazard, particularly during highway driving, merging, or intersections. Sudden loss of propulsion increases crash risk and endangers vehicle occupants and others on the road. In some cases, turbo failure can occur with little or no warning, further increasing risk. The failure was confirmed by INFINITI/Nissan service departments, and the vehicle remains available for inspection. CarMax insurance approved the engine repair, acknowledging mechanical failure; however, they declined to approve turbocharger repair specifically because INFINITI has issued a known TSB and extended warranty covering turbo failure, deferring responsibility to the manufacturer. Despite the vehicle being within the extended warranty limits, Nissan denied coverage, claiming the vehicle has a “branded title.” This claim is unsupported by VIN reports, the loan originator, and CarMax’s own title search prior to leasing all confirm the title is not branded. Nissan has provided no documentation supporting its assertion. Nissan N.A. reviewed and closed the matter despite the known safety defect and lack of evidence for the title claim. Represents a safety-related defect and improper denial of a manufacturer-recognized safety remedy, warranting NHTSA review.
Leak in the turbo causing oil to burn and create smoke from the exhaust
The serpentine belt on my 2018 Infiniti Q50 Sport became contaminated with oil immediately after dealer turbo replacement at the end of August 2025, causing the belt to slip, shred, and be pulled into the engine. This resulted in sudden loss of essential engine functions and poses a significant safety hazard. This failure was caused by improper repair at the dealership.”
The contact's son owns a 2018 Infiniti Q50. The contact stated that soon after purchasing the vehicle, there was an abnormal screeching sound coming from the brakes while depressing the brake pedal. There was no warning light illuminated. The contact's son took the vehicle to an independent mechanic to have the brake pads and rotors replaced. However, less than one month after the replacement of the pads and rotors, there was an abnormal grinding sound coming from the front passenger’s side brakes. The mechanic was notified of the issue, and the contact was informed that the brake calipers might also need to be replaced. The contact stated that while driving at various speeds, the engine temperature gauge indicated that the engine was hot(H), with white smoke coming from the exhaust pipes. The vehicle was taken back to the independent mechanic, but the mechanic was unable to determine the cause of the failure. The vehicle was taken to another independent mechanic and the contact's son was informed that the head gasket had failed, and an engine replacement was recommended. The dealer was notified of the failure, and the contact was informed that there were no recalls or warranty on the vehicle. The manufacturer was also notified of the failure and provided the same information as the dealer. The vehicle was not repaired. The failure mileage was approximately 88,000.
The airbag/srs light is on. I've read on multiple forums that this is a common occurrence with this model and year of Infiniti. It did not come on as a result of any accident/incident.
Airbag light turn on, on my dashboard, I checked it with a professional OBD2 scanner and shows a code which indicates a fault in the Occupant Detection System (ODS), which the scanner says it is very common for my vehicle. This puts my passengers at risk due to an airbag system fault. My vehicle has not been in an accident, nor has my passenger seat been messed with. I have spoken to other individuals with the same vehicle, also checked the forums for my specific vehicle and almost all of them have the same issue with the ODS, with no recalls or warranty resolution from the dealership. This is a common issue. It is concerning because there is a pattern of the ODS being faulty by no fault of our own but no resolution or recall.
Within one month of purchase, the airbag warning light illuminated and has remained on continuously. A separate dealership later confirmed the airbag system is defective and may not deploy in an accident. This is a serious safety defect that was not disclosed to me at the time of sale. Additional Issues: •On July 14, 2025, I dropped the car off for prolonged starting issues. I was told the vehicle had six faulty fuel pumps/injectors. •I have not had possession of the car since July 14. •On August 30, 2025, I received an email from Nissan of Orange Park stating the car was “completed and ready.” When I called the next day, I was told the car was not at Nissan at all, but at Infiniti, with no clear repair status or timeline. Concern: This is a federal safety defect. I request NHTSA’s review and investigation into Infiniti/Nissan’s handling of defective airbag systems in this vehicle and the misleading communication surrounding repairs.
My car wouldnt start and when it did, it would start shaking and every time I accelerate, The speed wasnt going any faster but only the RPMs were
I was driving down the highway leaving the barbershop and my car wouldnt go over more than like 55 mph and I got a flashing green symbol beside my check engine light which had just came on when the AUTO (Stop/Start) light did. once I got home turned it off and turned it back on the for a second the light doesn’t come on but once you drive it maybe a quarter of a mile or less it come back on and the car wont function properly again
Car has white smoke coming from the exhaust and the oil level keeps decreasing. Car stalls and takes time to accelerate P0106 code pops up from engine. There’s a rattle and whine noise coming from the engine bay. Also the gas was stuck accelerating. Had to switch the car to neutral so it does continue accelerating. After switching to neutral I was able to decrease power to the wheels and had to pull over on the road.
The contact owns a 2018 Infiniti Q50. The contact stated that while driving at an undisclosed speed, the "Low Oil Pressure - STOP", message was displayed, and the contact stopped driving the vehicle. The contact stated that while starting the vehicle, the engine was abnormally loud. The contact stated that the low oil pressure warning light was illuminated. The vehicle was towed to an independent mechanic, who diagnosed a failure with the timing chain. The vehicle was not repaired. 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 107,000.
Turbos are starting to work and car is starting to consume anti freeze
I was driving down the highway and my car started to shut down and started to make a knocking sound inside the engine bay, putting at risk other drivers, so i turned on my hazards and pulled to the shoulder of the road,the car wouldn’t turn on so i called a tow truck. Took the car to dealer and stated engine is seized
I was in my car waiting my for complex security gate to open when I heard a loud noise. I got out of my car to see what it was and turns out my sunroof exploded. For no reason. No rock or item hit my car nor was the car in motion. It was also not from the heat as it was 60 degrees outside. I called my warranty and they refuse to cover it because it is glass. I am reading many others with this same issue. How does a 6 year old car have the sunroof explode??
The airbag passenger light is illuminated causing air bag system to remain off until resolve. The vehicle was taken in for inspection and dealer confirmed diagnostic results found Occupant sensor malfunctioning. Under warranty, the sensor was covered, but after installation the system also found that wasn’t the only thing to replace. It’s a handful of sensors and harness that is integrated within the seat frame with the ONLY solution to replace the entire chair/seat frame. This item does not fall under warranty. My concern is the safety of my family riding in the vehicle. This issue was happening to 2016 and 2017 models that were recalled for the same issue. Unfortunately this vehicle may have been manufactured in 2017, but holds the 2018 year on paper found through carmax.
The Air bag system on a 2018 Infiniti Q50 AWD is malfunctioning. I’d like to get it checked out especially if this could be a tentative recall issue for myself and other owners of the same vehicle. I feel very unsafe for my family and I because the system was never tampered with, yet the light used to go away randomly. Currently, the light is permanently on, and passenger airbag light states the system is off from deploying in case of an accident. This would mean that I would be driving at a risk of airbags being non-deployable and that is truly unsafe. This problem was not addressed with a dealer or any other service center. The vehicle has never been inspected yet, but it is a concern that I’d like to move forward on. The passenger airbag light is illuminated on my dashboard as well as the light depicting that the system is off. I recently bought this car July 2022 and within six months from purchase the light started coming on randomly and disappearing. Now it is permanently on.
I went to Evo Motors to find a car and found a car filled out an application and had to return to the next day because they were closing There was already talk about a down payment but no credit transaction was happening yet. I didn’t even have an offer on the credit yet so I came back the following day and on the way there I got a phone call that the bank was requesting a down payment in the amount of $4500. The salesperson was requesting cash downpayment and I thought that was strange since that was a lot of cash to have on hand. Me and girlfriend had a decent score to acquire the car but the dealer insisted on the cash downpayment and told us the bank was requested the down payment in order to get the car. I was very uncomfortable but I needed the car as I had lost my previous car in an accident and I needed to get to work and was in a rental car. I demand my down payment back in the amount of $4500 plus interest and keep the car as the transaction was unconscionable. They took advantage of my position in the basic necessities and livelihood as I needed to keep working to survive. The added burden was that I had to call friends and family all day long to come up with a downpayment I didn’t have and I had to pay everyone back in a short time. I was so stressed that I got sick and have still not recovered from the transaction that took place that has led to the moment where it was not fair to extort funds I did not have to further benefit them even after had already enriched themselves with the sale of a vehicle that had a very high-interest rate for our credit profile. It’s obvious they had complete control over every aspect of this contract.
The contact owns a 2018 Infiniti Q50. The contact stated that the back-up camera was flickering while in use. The contact stated that over time, the back-up camera screen had gone blank and failed to operate as needed. Upon investigation, the contact discovered NHTSA Campaign Number: 19V654000 (Back Over Prevention) which she linked to the failure. The dealer was not made aware of the failure. The vehicle was not repaired. The failure mileage was approximately 130,000.
My coolant reservoir kept on going empty, I took to dealer for service they replaced the radiator fan module and told me my engine was not porous. I was driving and my engine ended up stalling, turned off while I was driving in the freeway at a high speed cause me to almost lose control of my vehicle because everything stopped working. It looks like an inner rod failed possibly because of the coolant going into engine.
2/1/2023 we took our 2018 Q50 to the Infiniti dealership and service center. The engine was having issues, increased RPMs while simultaneously experiencing loss of power/stalling. This was experienced by both my wife and I. Infiniti's determination was the Mass Air Flow Sensor and told us the issue was not covered by the platinum, bumper to bumper extended warranty they sold us due to the warranty only covering mechanical issues, not electrical. The service tech was able to get costs waived as factory warranty covered such events to 75k miles. We picked the car up on 2/8/2023. On 3/18/2023 the car was again towed to the dealership. The intermittent issue that was thought to be the Mas Air Flow Sensor and electrical, hit suddenly and with such force the car would not run whatsoever and stalled out on a very busy 50 MPH Parkway and my wife had to maneuver her way to safety with cars flying all around her. No obvious sign of electrical mass failure, lights still on, etc. On 3/24/2023 I received a call and was told the engine needed to be replaced, the cost was $32k, and that the warranty’s fine print says that the warranty will only cover up to the fair market value of the car, which they determined to be about $21k. I’m responsible for their faulty engine & poor mechanical workmanship? I was sent pictures of debris and springs sitting in the bottom of the dropped oil pan and a separate photo clearly showing a disintegrating cam shaft / lower engine area adjacent to the oil pan. Catastrophic and very avoidable failure (this is not an engine in a military vehicle or motorsports vehicle). I believe the problem was never the Mass Airflow Sensor, it was the alloys used in this area of the engine that were failing. This failure is not the first for Infiniti (have been reading forums)
vehicle has porous block and lead to engine failure. many other VR30DDTT engine equipped vehicles are having the same issue some are being replace and others are not. this needs to be a major concern for nissan/infiniti as they are a fantastic brand but some of the customers of these vehicles are being left high and dry with no options
The Blindspot on my car needs a sensor to signal a cars presence. I have to turn my neck and head all way around to see which is unsafe for myself and others on the road.
ON 6/13/2020 THE DRIVE BELT SHREDDED WHILE DRIVING UNDER 30MPH, UNDER LIGHT ACCELERATION. AT FIRST, THE BATTERY LIGHT ILLUMINATED ON THE INSTRUMENT CLUSTER, FOLLOWED THE CHECK ENGINE LIGHT. WHITE SMOKE BEGAN TO COME FROM THE ENGINE. THANKFULLY, I WAS NEARBY MY HOUSE AND MADE IT THERE SAFELY. FURTHERMORE, THE ENGINE OVERHEATED DUE TO A COOLANT HOSE BEING KNOCKED OFF BY THE SHREDDED BELT. ADDITIONALLY, THE WATER PUMP AND A/C COMPRESSOR FAILED. THE PULLEY TENSIONER ASSEMBLY AND BELT WERE REPLACED UNDER MANUFACTURER'S WARRANTY, ALONG WITH THE AFOREMENTIONED FAILED COMPONENTS. ALL WORK WAS DONE AT GRUBBS INFINITI OF GRAPEVINE, TX AND THE REPAIR TOOK EXACTLY THREE WEEKS TO FIX. THE FAILURE MILEAGE WAS 28,660. PREVIOUSLY, ON MARCH 6, 2019, INFINITI OF VAN NUYS, CA, TIGHTENED THE PULLEY TENSIONER ASSEMBLY DUE TO A SQUEAKING NOISE I WAS HEARING WHILE ACCELERATING. VEHICLE MILEAGE WAS APPROXIMATELY 10,000. I WAS INFORMED THAT IF I HADN'T HAD THIS ISSUE FIXED BEFORE MY DRIVE BACK TO TEXAS, MY DRIVE BELT COULD HAVE SHREDDED. AFTER THE DEALER ADDRESSED THE CONCERN NO FURTHER NOISE WAS HEARD AT ALL. THE DEALER ALSO INFORMED ME THAT THIS ISSUE IS KNOWN AND HAS BEEN DOCUMENTED IN INFINITI SERVICE BULLETINS. ALTHOUGH, THIS POSES A MAJOR SAFETY CONCERN AS THE VEHICLE COULD HAVE STALLED AT HIGH SPEED RESULTING IN AN ACCIDENT AND OR LOSS OF LIFE. I WORRY THIS ISSUE WILL HAPPEN AGAIN. TWO TIMES, TWO MANY!

GAS MILEAGE IS VERRY BAD ! IN CITY ONLY MY CAR GIVE ME 14 MPG AND HWY 18MPG INFINITI SAY IS. 20MPG CITY AND 29HWY. AND COMBINED 22MPG
THE PHONE/BLUETOOTH CONSTANTLY DISCONNECT DEVICES THAT ARE ADDED TO BLUETOOTH. OFTEN WHEN CALLS ARE MADE FROM YOUR CELL THROUGH BLUETOOTH, THERE IS A FRYING/STATIC SOUND THAT OCCURS. YOU HAVE TO HANG UP AND PLACE YOUR CALL AGAIN. THIS HAPPENS BOTH WHILE DRIVING AND STATIONARY.
THE SERPENTINE BELT MAKES CONSISTENT NOISE IN ALL TYPES OF WEATHER. ALREADY HAD THE DEALER REPLACE IT ONCE. NOISE CAME BACK AND THE DEALER NOW SAYS IT COULD BE THE TENSIONER PULLEY.
FROM START INTO THE WARM-UP, THERE IS A CONSISTENT WHORELING NOISE COMING FROM THE MOTOR.
AS I WAS PARKING THE VEHICLE AT 5MPH BEHIND A PARKED CAR, WITH THE FRONT TIRES SLIGHTLY TURNED TO THE LEFT, THE BRAKE PEDAL WAS DEPRESSED, THE VEHICLE SUDDENLY ACCELERATED BUT THE VEHICLE FAILED TO STOP. RESULTING IN HITTING THE VEHICLE IN FRONT AND PUSHING IT OUT OF THE WAY, THE VEHICLE CONTINUED MOVING DESPITE HAVING THE BRAKE PEDAL DEPRESSED TO THE LIMIT, THE ENGINE WAS REVVING VERY HIGH. THE VEHICLE CROSSED THE MEDIAN AND CAME TO A STOP ON THE OPPOSITE TRAVEL LANE OF THE STREET AFTER THE ENGINE WENT TO IDLE SPEED. THE DEALER SUGGESTED TO CONTACT INFINITI USA TO START AN INVESTIGATION(TBA), A POLICE REPORT WAS FILED. COLLISION AVOIDANCE/AUTO BRAKE DID NOT ENGAGE. VIDEO WITH SOUND OF THE INCIDENT IS AVAILABLE UPON REQUEST.
WHILE I WAS DRIVING MY INFINITI ON THE HIGHWAY MY SERPENTINE BELT SNAPPED 4 DIFFERENT TIMES WHILE IN MOTION. ALL WITHIN ONE YEAR. INCLUDING ME GETTING MY CAR BACK FROM THE DEALER AND THEM LETTING ME HAVE IT BACK THAT WAY. ALSO, THE TIRES ARE HORRENDOUS, FROM DAY ONE, THEY PULLED THE CAR LEFT OR RIGHT ON THE CAR. ALL THE SETTINGS WERE CORRECT ON THE CAR. I WANTED TO HAVE THE TIRES REPLACED, BY THE MANUFACTURER, AND THAT CAN BE DONE BECAUSE NO IT'S TO LONG AND EVERYONE TOOK TO LONG TO MAKE THINGS HAPPEN. NOT TO MENTION DUNLOP IS IMPOSSIBLE TO GET A HOLD OF.
RUN FLAT TIRES WENT FLAT ON A POTHOLE THAT WAS NOT EVEN REALIZED ON A SUNDAY WITH NO SERVICE STATION OPEN. EVEN IF THEY WERE, THE TIRE HAS TO BE REPLACED, CANNOT BE REPAIRED. THERE IS NO SPARE TIRE OPTION- WHEN CONTACTED, COMPANY REFUSED " NOT POSSIBLE". THIS IS NOT SAFE AT ALL AND MUST BE ADDRESSED. MUST HAVE SPARE TIRE ESP SINCE RUN FLAT TIRES CANNOT BE REPAIRED AND ARE NOT IN STOCK AT MOST SERVICE STATIONS
THIS WAS A RENTAL VEHICLE, NOT MY PERSONAL VEHICLE, BUT IS APPLICABLE TO MULTIPLE BRANDS AND MODELS. THE SAFETY ISSUE IS DUE TO THE HEADLIGHT MODES. THE DEFAULT MODE IS OFF, YET THE DRL'S REMAIN ON. THESE ARE BRIGHT ENOUGH THAT YOU CAN DRIVE IN THE MIDDLE OF THE NIGHT AND NOT REALIZE THAT YOUR ACTUAL HEADLIGHTS ARE OFF, WHICH MEANS THAT THE TAIL LIGHTS ARE OFF. I HAVE BEEN SEEING SEVERAL VEHICLES EVERY DAY WITH PEOPLE DRIVING WITH NO LIGHTS ON, EVEN IN POOR VISIBILITY. THE DEFAULT SHOULD BE FOR THE HEADLIGHTS TO BE IN AUTO MODE OR DRL'S MUST BE OFF WHEN YOU SELECT OFF. I HAVE BEEN SURPRISED SEVERAL TIMES THIS FALL BY DRIVERS DRIVING EXCESSIVELY SLOW WITH THEIR LIGHTS OFF ON THE HIGHWAY IN THE RAIN AT NIGHT. YOU CANNOT SEE THEM TILL YOU ARE VERY CLOSE. ALL OF THEM HAVE THESE NEW LED DRL'S ON AT THE TIME. THIS IS A UNIVERSAL ISSUE THAT NEEDS TO BE ADDRESSED. IT SHOWS A VERY BASIC LACK OF THOUGHT TO DESIGN HEADLIGHTS IN THIS WAY AND IS A SERIOUS SAFETY ISSUE IN MY OPINION.
CAR COMES WITH 19"RIMS AND RUN FLAT TIRES (BRIDGESTONE DRIVE GUARD). SINCE LEASOING THE CAR IN NOVEMBER 2018, I HAVE RECEIVED 8 FLAT TIRES ALL FROM "POTHOLES" THAT RIPPED THE SIDE WALL. CONSUMER AFFAIRS SAYS THIS TIRE SHOULD NOT BE ON THIS CAR IN CERTAIN STATES IN THIS CASE NEW YORK. INFINITI DEALERS DO NOT OFFER AN OPTION AND THE UNSUSPECTING CONSUMER IS LEFT WITH A HAZARDOUS SITUATION. YOUR EYES CAN LEAVE THE ROAD AS YOU SEARCH FOR EVEN SMALL POTHOLES TO AVOID. WHEN THE TIRE DOES GO FLAT AND YOU ARE MORE THAN 25-50 MILES AWAY FROM A REPAIR SHOP YOU ARE IN DANGER OF BEING STRANDED. I WAS STRANDED IN A SNOWY WOODED AREA AND HAD TO DRIVE 25 MILES IN TREACHEROUS CONDITIONS WITH A CHILD IN THE CAR JUST TO FIND A REPLACEMENT. THE TIRE SHOULD NOT BE ON A CAR WITH A HEAVY FRONT END PER THE TIRE DEALER AND TIRE REPAIR SHOP. INFINITI KNOWS THIS AND WILL OFFER TO PAY FOR A NEW TIRE, RATHER THAN PUTTING CUSTOMER SAFETY FIRST AND DISCONTINUING THIS TIRE/RIM IN NY STATE. IN SEVERAL INSTANCES THE POT HOLE HIT WAS LESS THAN THE WIDTH OF THE TIRE.
THE CAR CAUGHT FIRE UNDER THE HOOD AND COMPLETELY BURNED UP IN THE PARKING LOT AS I WAS EXITING THE VEHICLE UPDATED 12/4/18*JB
FAULTY "DISPLAY CONTROL UNITS" CAUSE BLUETOOTH SYSTEM TO BEHAVE ERRATICALLY, PLAY / PAUSE MUSIC OR SOUNDS, OVERRIDE USER CONTROLS, AND CAUSE SEVERE DISTRACTIONS WHILE DRIVING BY HAVING TO MANUALLY TURN OFF BLUETOOTH FROM PHONE. FAULTY DCU WILL OVERRIDE USER CONTROLS IN OTHER ASPECTS AS WELL. DCU WILL CAUSE REVERSE CAMERA TO DISPLAY NO IMAGE / SKEWED IMAGE / INTERFERENCE. CAMERA HAS STAYED ON THE SCREEN WHILE MOVING FORWARD IN DRIVE. HAS BEEN AN ISSUE IN THESE CARS SINCE 2014, SOME WORSE THAN OTHERS. THIS HAPPENS AT ALL SPEEDS, REVERSE CAMERA IS MAINLY AT LOWER SPEEDS BUT THE ISSUES WITH THE BLUETOOTH CAN HAPPEN AT ALL SPEEDS. IT'S MOST INCONVENIENT FOR ME WHEN COMMUTING ON THE HIGHWAY BECAUSE ONCE I DISCONNECT THE PHONE FROM THE VEHICLE THE VEHICLE WILL NOT RE-PAIR WITH THE PHONE MEANING I CANNOT USE BLUETOOTH THE REST OF THE DRIVE (UNLESS I STOP).
Component Failure Cascade Risk
Known patterns where one defect leads to more severe downstream failures
▸ Valve and piston damage — timing chain/belt failure causes immediate catastrophic engine damage at any speed
▸ Engine stalling at speed — fuel delivery failure can cause sudden loss of power in traffic or on highways
Complaint & Reliability Timeline
Annual complaints (blue) vs. composite reliability score (amber) — recall years marked in red
The blue line shows 42 total NHTSA complaints filed over 8 years, with the worst year being 2025 (10 complaints).
The amber reliability line averaged 95/100 across the vehicle's life — relatively stable, with the lowest point of 89/100 in 2019.
The recall (red dashed line) followed the first complaints by 1 year — a typical response window; neither unusually fast nor a pattern of denial.
Red dots on the amber line flag 2019, a year when complaints included crash events — these are the highest-severity incidents in the dataset.
