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.

So I've had to have 1 tire replaced already working on number 2. First one not sure what the problem was, but this tire is having problems holding air. It'll hold air for about 9 hours then the gauge on inside of car comes in saying low tire pressure.
