“Electrical failure indicator lit up. I was on my way to the dealership service center. Within 10 minutes of driving, the car completely shutdown right at a busy intersection and before an active railroad crossing. Tow truck was called by the police as the car was not starting and therefore undriveable.”
NHTSA complaint #11499634, filed 2022-12“My water pump went out on my 2021Q7. The car had 57271 miles on it. I looked up the Vin and it is not covered in the class action lawsuit however, my model and my year comes up but not my Vin. I feel a water pump should last until 100,000 miles.”
NHTSA complaint #11699105, filed 2025-11“I have heard a knocking and experienced sudden loss of power while driving- not electrical loss, but vehicle suddenly slows down and unable to pick back up speed effectively creating a safety concern when driving- especially at on ramps. A warning light comes on and then it will go off randomly with the loss of power. I have taken it in multiple times and was told it is an emissions issue and a vacuum hose issue that allows fluid to get into my turbos or something along those lines. …”

I got over as quickly as I could ( no more than 1/4 of a mile) and sat on side of PA turnpike as engine cooled. I was at bottom of an exit ramp. I slowly proceeded up the ramp and warning came on again and red temp light reached again. I pulled right into the gas station at top of TP exit ramp. It still said to continue to run the car. I sat with my son in the car and ran the car in the shade. …”
