“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.”

“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. …”

“While driving with my 4 year-old daughter a notification appeared on the driver display that there is an “Electrical Malfunction” and to call the service department. A few minutes later, while actively driving on the same busy road in my town, the vehicle completely turned off, including the power steering and ABS breaks. I was stuck in the middle of a busy intersection with no hazard lights and no ability to even shift the vehicle into neutral to move it. …”

“Driving on highway at 70 mph and high engine temp light came on. Said to pull over and continue to run car until temp decreased. 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. …”
