Engine
My 2016 Q50 was driving strangely, but no indicator light came on the dashboard. I took the vehicle to the dealer where I purchased it and was told that the engine is dying. No other information was given to me. I called the service advisor asking what in particular was wrong with my car, but he said he wasn't sure. I took issue with the fact that my engine died, and no warning lights what-so-ever showed on the dash. I would only take my car to the dealer for repairs, maintenance and oil changes. I also learned that cars should not go beyond 3,000 miles for an oil change, but for some reason Infiniti oil changes were 10,000 miles in between. I believe this could be a reason the engine…

Jun 5, 2026Service brakes
Something happened to cause power loss. I checked the recalls and work that was supposed to be performed but didnât get done like it was supposed to. I need to have it checked now asap! I see 2 engine replacements and also the turbos and 2 of the catalytic converters. The last 2 need replacing as well or itâs not going to be right.

OUTPUT SPEED SENSOR on 2016 INFINITI Q50t - Took vehicle in for oil and filter change 2 days ago. I drove the car about 40 miles, without incident. Went back to same place for state inspection yesterday. I drove about 2 miles from the inspection place and park in shopping lot. Went in business to shop for about 30 minutes. Returned to vehicle and drove about 100 yards through the parking lot. The car appeared to lose power and made a jerking movement as if it didn't want to go. I drove out onto a very busy street and we were almost rear ended by other traffic. I pulled up in another parking lot to assess the problem. I could not determine what was causing the car not to pick up speed. I…

The vehicle experienced a failure while driving, producing heavy smoke and requiring the car to be stopped immediately. The âLow Oil Pressure â Stop Vehicleâ warning light illuminated on 2/19/2026. The vehicle was subsequently taken to an Infiniti dealership for inspection. Upon evaluation, the dealer determined that both turbochargers have failed and are leaking oil. The turbochargers are covered under an existing warranty extension; however, the engine has failed also. The vehicle experienced a catastrophic engine failure at approximately 50,230 miles, after which both the engine and turbochargers were replaced under warranty with the cause listed as undetermined. Both the original…
Feb 19, 2026Air bags
* the passenger airbag light came on July 2025. I was not in a accident the light just came on. * 7/29/2025 I took my car in for service at Infinity of Las Vegas (the only Infinity dealership in Las Vegas) I asked to check why the airbag light was on. I was told the occupant sensor unit was abnormal. Sensor and module internally shorted out. Recommend to replace passenger front seat frame assembly (only available as a 1 piece both sensor and module internally shorted seat frame Assy). @ $ 8678.76. Because itâs a different seat from the original seat, I would have to also replace the seat belt. @ 116.87. * It is not recommended to drive a car with the air bag light on. This car is my only…

Iâm reporting a safety issue with my 2016 Infiniti Q50. Last Friday [XXX], my the car wouldnât crank and there was minimal dashboard power, but the engine wouldnât start. After receiving a jump, I had the battery replaced assuming it was the issue. However, six days later, while driving, the vehicle suddenly lost all electrical power mid-drive with no warning or dashboard alerts. The engine shut off, the brake pedal became stiff, and I was unable to use any power-operated functions, such as rolling down the windows (98 degree day in Texas) or opening the trunk, which contained my emergency tools. A police officer had to assist and the vehicle was towed. Upon inspection, the issue was…
