ISSUE 1: On [XXX], I was driving my vehicle ( License Plate [XXX], Vin# [XXX], Infinity 2017 Q50 Sedan, purchased in 2020 at Infiniti of Massepequa) on [XXX] ( a very busy highway on Long Island) traveling East.Suddenly the steering wheel locked and I could not turn the wheel. I was going straight on [XXX], and I tried to steer right and could not turn the wheel. Ater a minute I was able to force the steering wheel, against resistance, to the right and veered into the middle lane of the next cross street. I then had to back the car up at an angle in order to clear the next left turn. This enabled me to park on the right side curb while forcing the wheel to turn to the right. I needed to get…

Jul 31, 2026Steering
Affected: Steering/Electrical/Direct Adaptive Steering, 50K miles While driving my 2017 Infinity Q50s under normal driving conditions, the vehicle suffered an instantaneous, catastrophic, and total failure of the power steering assist system without any prior warning or dashboard fault indicators. The sudden loss of steering assist immediately caused the steering wheel to become incredibly heavy and virtually locked, requiring extreme, dangerous physical exertion to maintain minimal control over the direction of the vehicle. Due to the violent and unpredictable change in steering dynamics at speed, I was forced out of my lane and ran over a curb and came moments away from experiencing a…

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 itâs 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 hasnât 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.
Feb 9, 2026Wheels
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…

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…
