2017 INFINITI Q50 Problems & Complaints

I bought my q50 in 2020. In 2023 one of my turbo chargers began experiencing failure. This defect caused the car to drive in limp mode where it would not accelerate and caused a hazard to myself and other drivers on the road. The failure did not display any lights on my dash and I only came to know the component failed after the physical symptoms it presented and having it diagnosed by infinit. Infiniti has now issued an extended warranty for up to 120k miles on the part for owners with the defective turbos. The warranty letter also states that if owners previously replaced the part out of pocket they could seek reimbursement with proof of the repair and proof of ownership. I submitted my documents to Infiniti and they have since closed my case without reimbursement because they claim one of their associates made a mistake in beginning the claims process with me. I have attempted to continue to pursue reimbursement and Infiniti won’t return my calls. I know for certain my car and the turbo repairs qualify for this reimbursement. I believe Infiniti is attempting to work around officially recalling the cars impacted by the bad component and the warranty is being provided in its place however I also believe they are giving me such a hard time with this in hopes that I’ll just roll over and give up on the reimbursement

The engine in this car needs to be replaced. The main bearing is failing, head gasket blew, and coolant has leaked into the engine. About August 30, 2023 I had a sudden coolant loss followed by temperature spike. If the engine had seized while driving, it could have caused a loss of power and locked up the drive train. After sitting while i tried to determine the coolant loss and temp spike, i made arrangements with a local infiniti dealer about jan 9 with a drop off date of jan 22 or 23. The dealer has confirmed the bearing, oil, coolant issue. There were no warning lights or check engine lights before the issue occurred.

The car needed new sprockets after 105K miles. I haven't seen anyone else have this problem, so my car maybe a lemon. But just in case more people start reporting it, I just want to make sure it's on record. The dealership has no idea why they'd fail, as I have had regular, full synthetic oil changes. It's a hefty repair.

Engine failure due to porous motor and oil deprevation related to a tsb

CAMSHAFT POS SENSOR WENT OUT DURING DRIVING. CAR LOST POWER AND JERKED. HAD CAR LOOKED AT BY INDEPENDENT SERVICE STATION AND HEARD KNOCKING. BROUGHT CAR TO DEALERSHIP AND WAS DETERMINED TO HAVE A BLOWN ENGINE. WAS SPECIFICALLY TOLD THAT THE TURBOS WERE 'EATING' THE OIL AND NOT ALLOWING OIL TO FLOW TO LOWER END OF MOTOR. WHICH CAUSED FAILURE TO MAIN BEARING IN CYLINDER 3. CAR NEEDS A NEW ENGINE. SERVICE DEPARTMENT HAS SEEN THIS BEFORE WITH SAME YEAR MAKE AND MODEL OF VEHICLE

Unknown

Driver has noticed ignition delay. Cause is unknown. Tire change is due. Cause is regular wear and tear. Vehicle inspection can be scheduled. Delay places safety of passenger at risk. Unknown if problem has been reproduced or confirmed by a dealer or independent service center. Tires were inspected by Discount Tire on November 26, 2024. Place key close to ignition message is frequently displayed on dashboard.

I have repeated incidents of the car losing power while driving. The first time this happened was in 2018. Under the manufacture warranty both air sensors were replaced. The incident occured again in 2021. I had it towed to a dealership in Jacksonville. They were unable to repeat the failure.In 2022 it occured again. I drove the car to a Nissan dealership in Brunswick Ga. They reset some codes and the car drove ok. Today while driving I lost power again. I pulled into a parking lot and turned the car off. Once I restarted the car it drove ok. This has also occured on other occasions and seem to self correct if the car is turned off and restarted. There is no rhyme or reason to when this problem will present itself and could cause severe harm if driving in heavy traffic on the interstate.

My vehicles belt has torn twice leaving me stranded many other Infiniti Q50 owners have experienced it and Nissan has no solution but to replace it.

DRIVING 62-67MPH ON THE HIGHWAY, SUNROOF SHATTERED. LOUD SOUND OF SHATTER. I WAS IN THE VERY LEFT LANE (PASSING LANE). THERE WAS A VEHICLE THAT CUT ME OFF AND PASSED THE CAR IN FRONT OF ME ON THE LEFT SHOULDER WHICH MAY HAVE KICKED UP DEBRIS WHEN IT GOT IN FRONT OF THE VEHICLE IN FRONT OF ME FROM SHOULDER, BUT VIDEO DOESN'T SHOW IT. IT COULD HAVE BEEN A VERY SMALL PEBBLE OR SOMETHING. HTTPS://YOUTU.BE/8MBEKWTGYQW

I had a passenger seat belt light on and took it to Jim Coleman Infiniti in Bethesda,MD. They then were going to charge me a diagnostic fee to fix it, but instead proceeded to perform a zero point seat reset and got the error code B00A0 and then the passenger air bag light came on. They subsequently said that the vehicle was not covered under any recall or warranty and said that the seat needed to be replaced and informed me that it would be around 8000 at that time. Now it must be more. Looking at the recall campaign 16V244000 my vehicle does not qualify since it is one model year later, but I have seen others have the same issue that I have with the 2017 Q50. There is infact one in Florida that has a similar experience as mine. Talking to the dealer and Infiniti neither wanted to do a goodwill jesters and would only reduce the cost by a few thousand dollars. That still meant that I would need to put out more than 4000 to get a safety issue that should be covered. The symptoms and error codes are exactly the same. So I ask that you extend the recall campaign to the 2017 model year as well for the Q50. It is a safety hazard that will be present on the streets. The dealer also refuses to do the module reset saying that it will fail again. Pleas ask Infiniti to cover the cost of ensuring this critical safety for the passenger side is resolved for all model years that have the error code from the recall.

My airbags are currently disabled due to a faulty occupant detection system. I see that this was an Infiniti recall on many2017 Q50s, but my car is not included in the recall. The dealership confirms that my car is not part of the recall. The specific part involved in the recall is the front passenger Occupant Classification System (OCS), which triggers the error code being produced by my car.

The contact owns a 2017 Infiniti Q50. The contact stated while driving at an undisclosed speed, the passenger’s side seat belt warning light illuminated. The contact stated that there was no passenger located in the front passenger’s seat during the failure. The vehicle was taken to the dealer where it was diagnosed that the OCS sensor had failed, and the contact was informed that the front passenger's side air bag and the front passenger’s seat needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 86,000.

UNKNOWN Driver noticed increased volume of audio system without driver interference.

I went into Infiniti of Massapequa for an oil change I was told that my car has a recall for the ecm and by law they’re required to fix the recall in doing that it instantly caused a check engine light and are asking me to pay out of pocket for the oil pump adapter wire harness code P06DA repairs caused by the updated ecm I don’t feel that it is fair that I have to pay for anything due to issues from the dealers update of the ecm

SINCE MARCH OF 2020 I HAVE HAD ISSUES WITH THE DISPLAY SCREEN AND THE GPS SYSTEM. THESE PROBLEMS ARE ONGOING AND THE DEALER CANNOT REPAIR THE ELECTRICAL ISSUES. I HAVE ELEVATED THIS COMPLAINT TO INFINITY CUSTOMER AFFAIRS AND WAS ISSUED CASE# 43115404 TODAY. I HAVE TAKEN ATTEMPTED TO HAVE MY INFINITY DEALER FIX THE PROBLEM FOR ALMOST A YEAR AND THEY HAVE BEEN UNABLE TO REPAIR THE TWO ISSUES.THIS PROBLEM APPEARS TO BE GETTING WORSE AS THE FREQUENCY OF THE PROBLEMS IS OCURRING MORE OFTEN NOW.THE DEALER CONTACTED THE CORPORATE TECH ASSISTANCE DEPARTMENT WAS WAS DISAPPOINTED BY THE LACK OF SUPPORT AND THE REFUSAL TO APPROVE ANY REPAIRS. THESE ELECTRICAL PROBLEMS ONLY OCCUR WHILE THE VEHICLE IS BEING DRIVEN.

My vehicle's windshield washer sensor has malfunctioned as it regularly flashes a warning light indicating low washer fluid regardless of the actual washer fluid reservoir level. The persistent warning light on the dash is a constant distraction to the driver. Furthermore, a driver may become ambivalent to the warning light if another system actually malfunctions (or in the case of the washer reservoir actually being low or empty) thus creating a real safety threat. Infiniti vehicle forums as well as my independent mechanic note this problem to be fairly widespread and, according to my mechanic, is also prevalent in certain Nissan models. I brought this matter to the attention of Infiniti's Customer Care team but no action was taken to remedy the situation nor does it seem any action will be forthcoming. While this may seem to be a relatively small issue, such small issues can still result in significant negative outcomes if not addressed. Given the regularity in which this issue occurs, the manufacturer should be responsible for repairing this defect.

My sunroof exploded when I was driving. No warning. Weather was perfect where I was. No other vehicles around me, I was completely alone on the highway.

THIS CAR SOME WITH AN INTERNAL REAR VIEW MIRROR THAT IS SUPPOSED TO AUTO DIM (NO FLIP LEVER) MIRROR DOES NOT AUTO DIM. LIGHTS OF CARS BEHIND ME ARE FULL STRENGTH WHEN VIEWED THROUGH THE MIRROR I HAVE HAD THE CAR TO THE DEALER THREE TIMES FOR THIS AND I HAVE WORKED WITH INFINITI CONSUMER AFFAIRS. THEY TOLD ME THAT THIS IS HOW THE MIRROR WORKS. IT IS VERY UNSAFE I HAVE TO TILT THE MIRROR UP AT NIGHT AND AM UNABLE TO USE IT TO SEE ANYTHING BEHIND ME WHILE DRIVING.

I am the owner of a 2017 INFINITI Q50 purchased in 2019. My vehicle has suffered three separate turbocharger failures in four years: 2021 (~75,000 miles): turbocharger failure; replaced under my extended warranty (~$6,000 authorization). 2023 (~98,000 miles): turbocharger failure; replaced again under extended warranty (~$6,000 authorization). 2025 (143,000 miles): diagnostic confirms another turbocharger failure; quoted $8,900 out of pocket because my extended warranty has expired. These failures follow the classic symptoms of excessive exhaust smoke and MIL illumination that INFINITI has explicitly linked to premature turbocharger bearing wear in the February 2025 “limited emission warranty extension” for 2016–2018 Q50 and 2017–2018 Q60 vehicles. INFINITI’s bulletin states the company “is conducting a warranty extension to Full Useful Life (FUL) of 10 years or 120,000 miles” for select turbo assemblies where white smoke/oil-leak with MIL-on requires turbo replacement, and explains the reason as “possibility that the turbocharger bearing may leak engine oil internally due to premature wear.” INFINITI’s public owner-facing campaign page likewise describes this extension and its terms (10 years/120,000 miles), including reimbursement for qualifying prior repairs. Infiniti Assist While my current mileage exceeds 120,000 miles, my car has required two full turbo replacements before 100,000 miles and now requires a third at 143,000 miles. This pattern evidences a latent defect present well within the extension period and is consistent with the failure mode INFINITI acknowledges. They have offered no help and only assume 50% responsibility when they 100% have manufactured defective and poorly labored parts.

The contact owns a 2017 Infiniti Q50. The contact stated while driving 40 MPH and attempting to accelerate, the RPM increased quickly; however, the vehicle lost motive power, prompting the contact to discontinue driving the vehicle. Upon arriving at the residence, the contact shifted the vehicle into park and released the brake pedal, and the vehicle started rolling forward. The contact engaged the parking brake to secure the vehicle. No warning lights were illuminated. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 24V470000 (Power Train); but the VIN was not included. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA Hotline for assistance. The failure mileage was 112,000.

The airbag light came on for the passenger side. The dealership said I had to pay $246 to find out what the problem is. They told me the entire seat/airbag structure needed to be replaced at a cost of $6k-$13k. I searched the problem online and there is the exact recall for this car/problem but not my vehicle. I don’t feel like I should be responsible for a safety issue in a 7 year old car. I believe this model should be included in the recall. I also am requesting the $246 be refunded.

Air bag light came on which can render air bag inoperable in case of collision. Dealer states not under warranty. This is their results: UPON INSPECTION, FOUND DTC B00A0-00 TO BE STORED IN AIR BAG SYSTEM. Correction AS PER ITB19-024B, RECOMMEND 75 ZERO POINT RESET (CALIBRATIONS AND SYSTEM RESET/REPROGRAMMING NOT COVERED UNDER WARRANTY)

The contact owns a 2017 Infiniti Q50. The contact stated while driving at various speeds, the vehicle would shudder while the brake pedal was depressed. The contact stated no warning lights was illuminated. The vehicle was not taken to a local mechanic to be inspected. The manufacturer was not informed of the failure. The failure mileage was approximately 16,000.

I PURCHASED MY 2017 INFINITI Q50 ON OCTOBER 06 2018 FROM CARVANA LLC. THE VEHICLE WAS USED AND HAD APPROXIMATELY 38K ON THE ODOMETER. WITHIN 2 WEEKS OF OWNING THE VEHICLE THE REAR BRAKES PADS NEED TO BE REPLACED AND THE ROTORS NEEDED TO BE RESURFACED. THIS WAS EXPECTED DUE TO THE HIGH MILEAGE ON A 1 YEAR OLD VEHICLE. THEN ON JANUARY 11TH 2019 I TOOK MY 2017 INFINITI Q50 IN FOR ITS OIL CHANGE AT 43,000 MILES WITH GLENDALE INFINITI IN GLENDALE CALIFORNIA. WHEN THE SERVICE WAS COMPLETED THE SERVICE ADVISOR HAD NOTIFIED ME THAT MY REAR BRAKE PADS WHERE AT 4/32'S AND WOULD NEED TO BE REPLACED WITHIN 6,000 MILES. I HAD THE BRAKE PADS REPLACED WITH THE FACTORY RECOMMENDED BRAKE PADS AT FIRESTONE IN ALHAMBRA ON 6 OCTOBER AS STATED ABOVE. I DID TAKE THE CAR BACK TO FIRESTONE IN ALHAMBRA CA FOR SQUEALING BRAKES MID DECEMBER 2018 AND IT WAS ALSO DISCOVERED THAT THE FRONT BRAKE PADS NEEDED TO BE REPLACED ALONG WITH THE ROTORS NEEDING TO BE RESURFACED. THE REAR BRAKES NOW SQUEAL AND WILL NEED REPLACEMENT FOR THE 2ND TIME IN LESS THAN 3 MONTHS. MY CAR IS USED TO DROP MY SON OFF AT DAYCARE AND MY WIFE AT WORK AND THEN TO PICK THEM BOTH UP AND SOME OCCASIONAL TRAVEL AND WORK FOR MY PART TIME JOB AS A RIDESHARE EMPLOYEE WHICH TOTAL 859 MILES IN DECEMBER. I HAVE SEEN COMPLAINTS FROM OTHER OWNERS ABOUT HAVING THE REAR BRAKE PADS WEAR PREMATURELY. I ASK ED THE SERVICE ADVISOR WITH GLENDALE INFINITI ABOUT IT AND HE SIMPLY STATED IT IS DUE TO HARSH BRAKING. I RESPONDED WITH IS THAT SO BECAUSE THEY WHERE REPLACED WITH FACTORY BRAKE PADS IN OCTOBER 2018. SINCE THE FIND THE SQUEALING IS INTERMITTENT WHEN COMING TO A STOP AND MY STOPPING DISTANCE HAS INCREASED EVEN AT LOW SPEEDS ON CITY STREETS.

WHEN STARTING UP FROM BEING PARKED THE WHEELS STEER THE CAR TO THE RIGHT WHILE I HAVE TO PULL THE STEERING WHEEL TO THE LEFT TO KEEP THE CAR DRIVING STRAIGHT. THE MOMENT I REMOVE THE PRESSURE FROM PULLING THE WHEEL LEFT THE CAR TAKES AN IMMEDIATE RIGHT TURN. THIS IS NOT A FRONT END ALIGNMENT ISSUE AS THE PROBLEM WILL CORRECT ITSELF. IT HAS TAKEN AS SHORT AS A COUPLE OF MILES OR AS LONG AS A FEW SHORT TRIPS FOR IT TO CORRECT ITSELF. IT HAS HAPPENED FIRST THING IN THE MORNING, IN THE AFTERNOON AND EVENING. THIS SAFETY ISSUE STARTED WHEN THE OUTSIDE TEMPERATURE WAS STILL WARM. WHEN THE STEERING DOES CORRECT ITSELF I CAN FEEL THE STEERING WHEEL BEING PULLED TO THE RIGHT AND THEN THE CAR DRIVES STRAIGHT AGAIN WITHOUT ME APPLYING PULLING PRESSURE ONE WAY OR THE OTHER.

TL* THE CONTACT OWNS A 2017 INFINITI Q50. THE CONTACT STATED THAT THE POWER STEERING FAILED TWICE. THE VEHICLE WAS TAKEN TO RAY CATENA INFINITI OF EDISON (900 US-1, EDISON, NJ 08817, (732) 603-9600) WHERE IT WAS DETERMINED THAT THE VEHICLE WAS STILL UNDER WARRANTY. THE VEHICLE WAS REPAIRED, BUT THE CONTACT FELT UNEASY ABOUT DRIVING THE VEHICLE. SHE SPOKE WITH HER STATE'S ATTORNEY GENERAL'S OFFICE BEFORE CALLING NHTSA. THE MANUFACTURER WAS NOT NOTIFIED. THE FAILURE MILEAGE WAS 10,276. *TT CONSUMER STATED THE VEHICLE WAS PARKED IN MY DRIVEWAY WHEN THE POWER STEERING FAILED/MALFUNCTION THE FIRST 2 TIMES, THE THIRD TIME ON MAY 2ND I WAS LEAVING THE BANK PARKING LOT WHEN IT FAILED AGAIN. IT WAS TOWED 3 TIMES TO THE DEALER (RAY CATENIA INFINITI IN NJ) THE CAR IS CURRENTLY AT THE DEALER. I DID CONTACT THE MANUFACTURER AND AFTER THE FIRST 2 FAILURES THE OFFERED ME AN EXTENDED WARRANTY OF 7 YRS/ K100 MILES, I WAS ABOUT TO ACCEPT WHEN IT HAPPENED THE FOR THE 3RD TIME AGAIN. I AM VERY AFRAID TO DRIVE THIS VEHICLE, THE NEXT TIME I MAY NOT BE SO LUCKY. I DON'T HAVE THE TIRE INFO SINCE THE CAR IS IN THE DEALER'S SHOP. *JB *DT*JB

DUNLOP SP SPORT 5000 DSST P245/40RF19 DEVELOPED SIDEWALL BUBBLE SPONTANEOUSLY.HAD TO REPLACE TWO TIRES AT LESS THAN 30,000 MILES. BOTH TIRES HAD PLENTY OF TREAD LIFE LEFT (> 6/32)

I RENTED A VEHICLE FROM HERTZ AT GEORGE BUSH INTERCONTINENTAL AIRPORT IN HOUSTON, TEXAS FRIDAY MAY 18, 2018. ABOUT 2 HOURS INTO MY TRIP I CHECKED THE VEHICLE INFORMATION AND DISCOVERED THAT THE TIRE PRESSURE WAS NOT AT MANUFACTURES SPECIFICATIONS (35PSI). THE FRONT TWO TIRES WERE AT ABOUT 44PSI, THE REAR DRIVERS SIDE TIRE WAS AT 59PSI AND THE REAR PASSENGER TIRE WAS AT ABOUT 40PSI. I IMMEDIATELY CALLED HERTZ EMERGENCY ROAD ASSISTANCE (8006544174) AND NOTIFIED THEM OF THE ISSUE. I WAS ADVISED TO NOTIFY THE LOCATION UPON RETURNING THE VEHICLE. AFTER MAKING THIS CALL I WAS IN AN AUTO ACCIDENT. THE VEHICLE HYDROPLANED AND SLID ACROSS THE HIGHWAY, EVENTUALLY MAKING ONE OR MORE 360 TURNS UNTIL STOPPING. I CALLED HERTZ EMERGENCY ROAD ASSISTANCE TO NOTIFY THEM OF THE INCIDENT AND WAS ADVISED TO DRIVE TO THE CLOSEST OPEN LOCATION WHICH WAS OVER 130 MILES FROM THE ACCIDENT, SINCE THE VEHICLE WAS STILL OPERABLE. I DO NOT BELIEVE THAT THIS INCIDENT WAS A RESULT OF MANUFACTURE ISSUES, I DO HOWEVER BELIEVE THAT NEGLIGENCE ON BEHALF OF THE RENTAL CAR COMPANY IN MAINTAIN THE VEHICLE RESULTED IN THE VEHICLE HYDROPLANING. WHEN I RETIRED TO THE HERTZ LOCATION AT BUSH INTERCONTINENTAL, I SPOKE WITH ALEC, A MANAGER AT THE LOCATION, AND HE CONFIRMED THAT IT IS STANDARD PROTOCOL THAT TIRE PRESSURE IS CHECKED FOR ALL RETURNED VEHICLES. IF THE TIRE PRESSURE ON THIS VEHICLE WAS NOT CHECKED I AM CONFIDENT THERE ARE OTHERS WITH THE SAME OR SIMILAR ISSUES. I AM NOT SURE IF THIS IS THE PROPER AUTHORITY TO HANDLE THIS MATTER BUT I DO BELIEVE AN INVESTIGATION OF SOME SORT IS NECESSARY. ATTACHED TO THIS COMPLAINT ARE PICTURES OF THE CAR TRIP INFORMATION WITH PSI. THE PICTURE FROM FRIDAY WHEN I ORIGINALLY NOTICED THE ISSUE. THE PICTURE FROM SUNDAY AT 3:12 WAS SHORTLY AFTER THE INCIDENT AND THE PICTURE AT THE MOBILE AIRPORT IS WHEN I RETURNED THE VEHICLE. THERE IS ALSO A PICTURE OF DAMAGE

I PURCHASED MY 2017 INFINITI Q50 AS A CERTIFIED DEALER OWNED VEHICLE WITH 4710 MILES ON IT FROM AIRPORT INFINITI ON 12/31/2018. SINCE TAKING POSSESSION OF THE CAR, I HAVE HAD THREE SEPARATE INSTANCES WHERE MY CAR LOST POWER DURING ACCELERATION, IN WHICH ONE OF THE INSTANCES NEARLY CAUSED ME TO BE HIT BY A SEMI-TRUCK WHEN CROSSING A DIVIDED HIGHWAY. I HAVE PROVIDED VIDEOS TO THE MANUFACTURE BUT THEY HAVE REFUSED TO TAKE ACTION BECAUSE THE VEHICLE DOES NOT SET ANY DTC CODES. WHEN THIS CONDITION HAPPENS MY 3.0T Q50 ACCELERATES EXTREMELY SLOW EVEN WITH 100% THROTTLE. THE NET RESULT IS THAT WHEN I INTEND TO CROSS A DIVIDED HIGHWAY, I EXPERIENCE A 1-1.5 SECOND DELAY FROM THE TIME I PUSH DOWN THE ACCELERATOR TO WHEN THE CAR BEGINS TO MOVE, THEN THE ACCELERATION FROM 0-15MPH CAN TAKE UPWARDS OF 5-6 SECONDS. THE RESULTING FEELING IS A CAR THAT ROLLS INTO A DANGEROUS INTERSECTION AND EXHIBITS STALL LIKE CONDITIONS. ONLY ONCE DID THE CAR SET DTC CODES DURING THIS INSTANCE. THE CODES SET WERE B130D, C1A16 AND PO340. THESE CODES SET THE FIRST INSTANCE, BUT HAVE NOT SET DURING THE PAST TWO OCCURRENCES OF THE SAME ACCELERATION ISSUE. THESE INSTANCES ARE COMPLETELY RANDOM WHICH MAKE THEM EXTREMELY DANGEROUS. FOR INSTANCE, THE CAR WILL BE DRIVING COMPLETELY NORMAL, I WILL STOP AND AN INTERSECTION AND THEN WHEN I GO TO TURN OUT INTO THE INTERSECTION, I GO INTO THIS STALL CONDITION WITHOUT WARNING. THE DEALERSHIP HAS HAD THE CAR 4 SEPARATE TIMES AND EACH TIME THEY HAVE REFUSED TO FIX ANYTHING ON THE CAR, DESPITE HAVING A VIDEO OF THE OCCURRENCE AND CONFIRMING THAT THE ACCELERATION WAS ENTIRELY ABNORMAL. I HAVE NO CHOICE BUT TO DRIVE THIS CAR IF INFINITI REFUSES TO FIX IT, BUT FEEL IT IS LIKELY THAT IT WILL CAUSE INJURY OR DEATH TO ME AND MY FAMILY IF I DRIVE IT. I HAVE ATTACHED A SUMMARY OF THE DAILY LOG I HAVE BEEN KEEPING SINCE I PURCHASES THE CAR ON 12/31/2018.

TL* THE CONTACT OWNS A 2017 INFINITI Q50. WHILE MAKING A LEFT TURN AT 10 MPH, THE VEHICLE SUDDENLY ACCELERATED. THE BRAKE PEDAL WAS DEPRESSED, BUT THE VEHICLE FAILED TO STOP. AS A RESULT, THE CONTACT'S VEHICLE REAR ENDED ANOTHER VEHICLE. THE AIR BAGS DID NOT DEPLOY. THE CONTACT SUSTAINED NECK INJURIES THAT REQUIRED MEDICAL ATTENTION. A POLICE REPORT WAS FILED. THE VEHICLE WAS TOWED TO THE DEALER (INFINITI OF MANHASSET, 1225 NORTHERN BLVD, MANHASSET, NY 11030) TO HAVE THE BRAKES DIAGNOSED, BUT NO REPAIRS WERE PERFORMED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE AND REQUESTED A REPORT OF THE VEHICLE'S DATA RECORDER. THE CONTACT WAS AWAITING A RESPONSE FROM THE MANUFACTURER REGARDING THE DATA RECORDER REPORT. THE FAILURE MILEAGE WAS 8,000. *TT

My vehicle has been stalling and burning/leaking oil internally for some time now with white smoke coming from the rear. Well Infiniti sent a post card and stated that the emission warranty is extended for 120,000 miles which my vehicle has had the issue for some time and it was already over 120k miles at the time of the loss. The issue Infiniti reported in their postcard is, you may experience issue with the turbocharger, Overtime there is a possibility for the turbocharger thrust bearing to wear and leak oil internally. The most likely conditions you will experience are excessive white smoke from the exhaust, MIL-On an in rare cases reduced engine power or damage to the internal components. My vehicle is experiencing all these issues reported and the company, Infiniti, knows this is an issue and did not issue a recall the extended warranty instead, most people will not qualify for which will require people to thousand of dollars replacing the turbocharger assembly and engine control model. I got a quote and was told 8000 dollars unfortunately I cannot have repairs done. I believe it was January 2025 when the post card came from Infiniti identifying the issue

The engine and turbo system failed in my 2017 Infiniti Q50 Signature Edition (VIN [XXX] ). The vehicle remains at CarMax Naperville, where it has been since March 2025. Internal repair orders show CarMax performed two failed inspections in August 2020 before selling the vehicle as “CarMax Certified” on September 3, 2020. The vehicle should not have passed certification. Shortly after purchasing the vehicle, I noticed it was pulling hard to the right. During my first tire rotation and oil change, the technician informed me that all four tires were severely dry-rotted and unsafe to drive on. CarMax had represented the vehicle as fully inspected and road-ready. These conditions suggest the vehicle had sat for an extended period after a prior four-point accident and should have never been certified for sale. None of this was disclosed to me at purchase. In March 2025, the engine failed. CarMax later reported that a replacement engine was installed, part #10102-6HN3A (single-turbo) instead of the required #10102-5CH2D (twin-turbo VR30DDTT). This engine does not match the original factory specifications for my VIN. Infiniti of Naperville confirmed that my vehicle qualifies for a free extended turbo and engine warranty (TSB P4A05/P4A06), but CarMax declined to use the required OEM one-time-use parts, voiding that coverage. CarMax has refused to provide inspection reports, diagnostic data, emissions test results, or engine serial numbers despite over forty written requests. I have no documentation confirming what work was performed or whether the vehicle is safe or compliant with emissions standards. The car has now been sitting at CarMax for over seven months, with rusted brakes and unknown mechanical condition. They are just concerned about me coming to get the car. This raises serious concerns about safety, emissions compliance, and potential consumer fraud involving improper certification and undisclosed prior damage.

Subject: Urgent: Check Engine Light After Vehicle Return I am contacting you regarding my vehicle, I dropped it off the dealer for oil change & they informed me it was recalled so they have to fix it, but they returned it to me with engine light on. They mentioned after fixing the recall the engine light came on…tested it and showed thermostat, but to pay 249 for them to diagnose because it’s a different problem, but that issue wasn’t there when I took my car. I have never had the check engine light on. I want my car back without the check engine light on. They now saying it’ll be $2700 to fix that. I said, no. They mentioned giving me a discount and it’ll be 1800 and they’ll cover labor. I said, all I want is my car back the way it was when I brought it. Then they changed it to $3400 I am very concerned about this and would like to understand why the vehicle was returned to me in this condition. I ask that you please review this issue and arrange for a prompt inspection and resolution — at no additional cost — as this may be related to the recent service or handling by your team. Please respond as soon as possible with next steps. I’d prefer to resolve this directly with your service department, but I will escalate the matter if necessary. Sincerely, [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My car has a start and stop problem and the dealer reprogram the ecm but it didn't work got back on the road and almost got hit twice bc my car went into limp mode. And they won't fix up unless I pay even know it's a recall and my drive shaft has a recall but they said that was close out

In October of 2023 I was driving onto the high way and my car just started to slow down I could not accelerate that gas while I was on the highway which is very dangerous when you are on the highway. My car turn off completely the engine light started to blink. All the lights were blinking. The only thing that was on was my radio. I could not move the car I was having. Trouble putting the car into park. Everything was stuck. Good thing I was not in the middle of the highway and not on a really busy highway but it was late at night. Drivers on the high way and myself are out at risk I could not even put my hazards on. A car could have crash into me and serious injury’s could have happen. I was stuck and was having trouble putting the car in park. Could not go into neutral. For a car to come to a sudden stop not be able to put the car in park that can be a risk factor due to if the car turn back on going into neutral on its own. The car was fixed with new engine at an auto body In July or August 2024 Now the engine light is on again the car will not even turn on. All the oil leaked out. Infiniti did my last oil change and said it was due at 117k which that is my current reading. When the oil all leaked out the car had a steering issue it crashed into a guardrail. That is the second time the car slow down had some type of issue is a big risk factor In August 2024 when the oil came out the car that can cause a fire and lost of steering the car crashed into rail with us in it. I did not have any warning signs about this going to happen. The car has not been driven since

Vehicle stalls or shuts down while driving. Diagnostic code is low fuel pressure.

The seat belt light went on without a passenger and the dealer decided to perform a zero point reset on the passenger seat and that resulted in a failure and now the airbag light is on. This causes the passenger airbag to not be operational. Before it was just the seat belt. They are now asking for $8000+ to replace the seat and OCS module and they said that they would cut the price by 50% but that is still $4000. The seat belt is covered by 10 year warranty but the airbag is covered only 7 year. I feel that since the seat belt was the iniial problem that it should all be covered under the warranty. Searching online there are numerous other Infiniti owners are having the same issue with the passenger seat and they are all being told that the seat needs to be replaced. This looks to be like a fauly module issue and thiink that Infiniti should be responsible for the fix. This has been happening with models from 2014-2018 two different series of Q50 models. THIS CAUSES THE PASSENGER AIRBAG TO BE NON OPERATIONAL AND FEEL THAT THERE ARE A LOT OF Q50 and other models on the road that are NO LONGER SAFE TO DRIVE!!!!

I took the car into the dealership to diagnose the reason that I was getting a Seat Belt light and they said that the guide suggested to do a zero point reset on the seat. When they attempted this they said that it failed and now the system has an airbag light on. There is no more seat belt light on now for the passanger side, but there is a hard error code for the airbag system on the passenger side. The Dealership now says the cost to repair is over $8500 when the car is only valued at $10000. I saw that there was a voluntary recall on a 2016 edition and it said that if the zero point reset should fail then the OCS module needs to be replaced, but now they are saying tha the OCS module and Seat need to be replaced. This looks to be like an issue with the model itself. The reason this is a safety issue, is that now the airbags will not work on the passenger side. This is caused by the zero point procedure that Infiniti has instructed their techs to do. I believe they are causing issues and had this not been needed then I would not have had an airbag issue. If there was an airbag issue before this procedure then the symbol was not correct and was false. It was a safety issue since the Passenger side airbag will not deploy in this case.

The sunroof leaks when it rains creating water inside the interior that holds standing water. It has caused issues with mold which my son it highly allergic to. This issue seems to be a common defect in sunroofs for Infiniti. I've had it repaired, but the problem persists. I have to park it in the garage but I'm not able to when I'm at work.

Hydraulic Bushing of the Lower Control Arm Leaking, very common problem amongst Q50 models.

Independent service center ran diagnostics and Code that pops up is the P0090. FUEL PUMP .no inspection by dealership when requested. We called dealership and they wanted to charge for inspecting vehicle. When driving vehicle stalls,in the middle of traffic. Check engine light turned on .No exaleracion when I press gas pedal. Very dangerous it stalled in the middle of traffic with children in vehicles.. the car goes to limp mode and didn't want to move . The muffler smokes and when checked the engine oil smells like gas.

The contact owns a 2017 Infiniti Q50. The contact stated while driving 50 MPH and depressing the accelerator pedal, the vehicle hesitated to respond. The check engine warning light was illuminated. Additionally, the contact stated that the vehicle was experiencing inaccurate fuel gauge reading. The contact stated that the failures had been recurring while driving. The vehicle was taken to the dealer several times, and the dealer diagnosed that the fuel pump had failed. The vehicle was not repaired.
