    NHTSA complaint 11674402
  3. Filed Mar 30, 2025Failure Mar 29, 2025Fort Lee, NJElectrical system

    Car turns off completely while driving with "Battery malfunction" and "Towing not permitted" error. This happened while driving on a highway at the end of a bridge going downhill so I was able to pullover to the shoulder before the vehicle came to complete stop but if this happened while on the bridge going uphill, that could've been extremely dangerous as there was no shoulder to pull over to. This has happened about 5 times already and we've taken it to the dealership. They upgraded the vehicle's software at one point saying that would address the issue, but the issue keeps happening. I don't feel safe driving this vehicle knowing that the vehicle can come to a complete stop at any time without any warning.
