2017 INFINITI Q50 Complaints

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. Sincerely, [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.
