Top problems in owners’ words
Verbatim from NHTSA complaints, newest first
Engine
17 reports1 crash
“I have had several major problems with this car's engine. Once it shut down (was detecting no oil but was full) while on the interstate. Had to replace the radiator fan assembly and module. Coolant Leaks”
Air bags
10 reports1 crash2 related recalls
“The contact owns a 2017 Infiniti Q50. The contact stated that while driving at an undisclosed speed, the air bag warning light illuminated. The vehicle was taken to an independent mechanic, where it was diagnosed with air bags failure. The contact was informed that the air bag needed to be replaced. The vehicle was not repaired. The contact was informed of an unknown recall; however, the VIN was not associated with a recall related to the failure. The contact was advised to contact the NHTSA Hotline to report the failure. The contact stated that the vehicle failed to pass State Inspection due to the failure. The manufacturer was not made aware of the failure. The failure mileage was unknown.”
Fuel/propulsion system
8 reports
“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.”
Electrical system
8 reports
“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”
Service brakes
7 reports1 crash
“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,…”
Seats
5 reports
“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.”
