2023 Infiniti Q50

I am reporting a potential safety defect involving my leased 2023 Infiniti Q50, VIN [XXX]. In 2024, I brought the vehicle to the dealership because the passenger seatbelt warning activated even when the passenger seat was unoccupied. I was told the condition was caused by objects triggering the passenger seat sensor, and no further repair was performed. On XXX, I returned to the dealership for a routine oil change and again reported that the seatbelt warning problem was continuing. I was initially informed that a component in the passenger seat required replacement and that the defect affected the passenger-side airbag system. I was later informed by the dealership that the defect affects both airbags, not only the passenger-side airbag. The dealership advised that the required replacement part must come from Japan. As of XXX, the part has not arrived, the repair has not been completed, and the vehicle remains awaiting the necessary part. My concern is that the airbags may have been inoperative or compromised for an extended period after I first reported the related warning issue in 2024. My wife and daughter drove and rode in this vehicle believing its safety systems were functioning properly. Had the vehicle been involved in a collision, they could have faced a substantially increased risk of serious injury. I am submitting this complaint so NHTSA can investigate whether this is an isolated defect, a dealer diagnostic failure, or part of a broader safety problem affecting other 2023 Infiniti Q50 vehicles.

While driving my vehicle on 12/06/2025, a wheel separated from the vehicle at the knuckle/ball joint area. This resulted in an immediate loss of safe operation and required the vehicle to be taken out of service. The failure involved the wheel/suspension/steering assembly. This event created a serious safety risk, as loss of a wheel while in operation can cause loss of control and endanger the driver, and other motorists. The vehicle became unsafe to drive and has not been operated since the incident. The vehicle has not been repaired. It remains available for inspection and is currently being held at an authorized dealership. No teardown or repairs have been performed. The issue has not been reproduced because the vehicle has not been driven since the failure. The failure has not yet been confirmed through repair, as no repairs or disassembly have been authorized. The manufacturer has been notified. No inspection or written findings have been provided by the manufacturer to date. Insurance representatives and dealership personnel are aware of the incident, but no corrective action has been taken. There were no known warning lights, messages, or abnormal symptoms immediately prior to the failure. The wheel separation occurred suddenly without prior indication.

I’m reporting a recurring safety issue with my Infiniti Q50 involving the brake, steering, and acceleration systems. While driving, I’ve experienced the brake pedal becoming unresponsive, the gas pedal not reacting, and the steering wheel locking or feeling stiff, making it extremely difficult to control the car. The most recent incident occurred today, [XXX]. I had to stop driving immediately and had the car towed to an Infiniti dealership, where a full systems check was performed. However, since the issue didn’t replicate while there, the dealer said they could not determine the cause. The car is available for inspection if needed. The safety risk is severe: I could not stop or accelerate safely, and I struggled to steer — this put me and other drivers in danger of a serious accident. I have experienced this more than once. The dealership originally diagnosed worn brake pads, which I had replaced at an independent shop, but the problem continued afterward. I also showed the dealership photos of the warning symbol that appeared on my dash during both incidents. The car has been inspected by the Infiniti dealer and an independent mechanic, but no resolution has been found. No inspections have been done by police or insurance. Given the serious nature of this malfunction, I am requesting this be investigated as a possible safety defect. Thank you, [XXX] Suffern, NY [XXX] [XXX] Infiniti Q50 2023 INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Vehicle was parked in my driveway with the engine running for about 5-10 minutes while I was going into the house to turn off my alarm, then return to take out 2 of my elderly dogs; & finally to take out my other dogs. I then returned to the car, opened the driver's side front door & reached in to push the "stop" button on the dash. As soon as I did, the vehicle immediately went into reverse & pulled me down the driveway by the open door. The vehicle continued down the driveway & crossed the street, hitting a fire hydrant in my neighbor's yard across the street. I never physically got into the vehicle to do the steps required to put the vehicle into reverse, i.e. putting my foot on the brake & depressing the transmission shift button. I contacted the dealership where I purchased the vehicle after the incident & explained what had happened. I spoke to Francisco, but he said there was nothing he could do unless I wanted to pay for diagnostics on the vehicle. I explained that the vehicle had clearly malfunctioned since I was not physically inside of the vehicle to put it into reverse. I asked him to document the incident, but he said he was unable to & suggested I contact Infiniti Consumer Affairs. I did that immediately after speaking with Francisco, & gave a detailed description of the incident. I was given a Case Number at that time. I called another Infiniti dealership to explain the situation to ask about diagnostics, & was informed that the car's computer would not give an error code for the car going into reverse. I called to speak to my dealership service advisor & was able to schedule a diagnostics appointment at no charge. I did an internet search & discovered it could be a linkage issue, which is a safety issue & the recommendation was for the vehicle to NOT be driven. I have since scheduled an inspection with Nissan Corp. but the rep was not receptive to my request for repairs. I supplied a video to the dealership, but Nissan said they did not have it.

My vehicle was stolen by theives using some kind of device to gain access because I have both key fobs that came with the vehicle but somehow they were able to gain access and start it and drive off. I believe this is a security and safety concern for Infiniti vehicles. it should not be easy to steal a locked, secured vehicle.
