NHTSA investigations into the 2024 Infiniti QX50
An investigation is the step before a recall: the agency has seen enough
complaints to look into a pattern itself. An open one means it thinks
something may be wrong and nothing has been fixed yet.

I was driving from [XXX] to [XXX] on Saturday, March 28th. I started smelling a strong, chemical odor and my eyes started burning and watering, so I pulled off of the highway and found that my back passenger side seat heater had started burning. There was a pillow and a down jacket on the seat that also burned. It really scared me because I was in the middle of nowhere and only had a cup with ice, but luckily there was a mud puddle that I was able to get some water from and pour on the back seat. My granddaughter was riding in that seat in her booster seat the night before. I am thankful she or no one else was in the seat when it burned. There were no warning lights or messages appear - I just smelled the burning. I had to continue to drive the car with the windows down to my son's home in West Virginia, and on Monday, March 30th, we took the car and dropped it off at the nearest Infiniti dealership (Cochran Infiniti in Monroeville, PA). We spoke with the service manager and many employees came to inspect and they all said they had never seen anything like this before. They confirmed there had been no recalls on the vehicle.

ELECTRICAL SYSTEM
The system falsely beeps and displays collision alerts even when no vehicles or objects are present. The system has also initiated braking on the highway with no obstacle present, which is a major safety concern for me and for other drivers. Conversely, when an actual vehicle approached too closely, the system failed to alert or respond at all.
