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

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 s

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.

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.
