2017 INFINITI Q50 Recalls, Complaints & Safety

The passenger seat occupant sensor is on. Dealer confirmed the code is related to a bad sensor so even if someone is sitting in the passenger seat and we are in an accident the airbag will not deploy. The dealer said a recall exists for earlier models but not for the 2017 even though they say it’s the same components. They want to charge me between $6,000 to $8,000 to repair which is almost as much as the car is worth. This unfortunately is cost prohibitive at this time so we are driving with the known risk. The light has been on for a couple of years now as we were hoping an additional recall would come out but it hasn’t which is why I am submitting this report.

The problem is on the recall, I understand my car is not on the VIN recall list but it's the same problem. Potential Recalls for 2017 Q50: Fuel Pump Control Module (2.0L engines): Improper software may cause the engine to stall.

I experienced an ongoing grinding/rattling noise from the wheel/brake area. The vehicle was serviced multiple times by a franchised dealer, which diagnosed the issue as brake-related and performed brake repairs. The noise was not resolved, and the vehicle was returned in the same condition. Shortly after service, an independent mechanic discovered a cracked/broken brake pad installed on the vehicle. Due to safety concerns, the manufacturer authorized inspection at a separate franchised dealership under different ownership. That inspection confirmed aftermarket brake pads, rotors, and related components of unknown origin installed on both the front and rear, missing OEM hardware, improper lubrication, and wheel bearing issues contributing to the noise. The inspecting dealer documented that the braking system must be returned to OEM specifications before safe operation and further diagnosis could continue. Despite this, the manufacturer has declined to require OEM remediation, and the vehicle continues to operate with unauthorized aftermarket brake components. The grinding noise has continued and has since shifted toward the rear. The condition is reproducible, documented by video, and confirmed by independent inspection. I believe the vehicle was returned to service in an unsafe condition involving a critical braking system.

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 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.

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.

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

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.

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.

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

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

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.

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.

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.

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.

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 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.

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 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. The manufacturer was notified of the failure and informed the contact that the VIN was not included in NHTSA Campaign Number: 17V476000 (Fuel System, Gasoline, Electrical System). The manufacturer referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 70,000.

When i was driving in highway, all of a sudden gas paddle stop working no matter how hard i press it is not taking gas paddle and not picking up speed. I was panicking, lucky nobody behind me. Nothing bad happen, but this is very dangerous in my opinion.

Turbos blow prematurely, and the motor can end up with porus block at any mileage
