Owner report 11564507 · 2024-01-09 (January 9, 2024)
The car radar system apparently had a glitch and locked up the wheels while I was driving 25 mph. Yes, it is available for inspection. We are afraid to drive the car, it is just sitting. The car locked up so suddenly it made the rear wheel come off and rear of car fell to the ground. I was bruised by the seatbelt from the sudden stop. The dealer acted like they were unable to inspect it, I had the car towed there since it is under warranty. They said it had been in an accident. It had not been in an accident. I had to have policemen direct tra…

Owner report 11507694 · 2023-02-16 (February 16, 2023)
I had been driving the car for about ten minutes when the 48v battery malfunction light came on. Within seconds, another warning appeared that said coolant was too hot, and the acceleration stopped accelerating and then went to a complete stop in the middle of the road.

When I restarted the car, it worked fine and I was able to make it home. If this had happened on the interstate, I would not have had time t…
