I hit a pothole a couple of days ago and my car wouldn't start...

I called mbrace they came to give me a boost and that didnt work.

Then the tow truck came to take it away , then the car starts out of nowhere.

Made an appointment for the dealer.

They said the negative cable that connects to the starter was loose.

But after that day, I am experiencing other issues, when I'm driving the command screen starts to flicker. The dealer didn't notice it. But its really hard to catch it happening , since it happens out of nowhere.

Any recommendations.

 

Bring it to the dealer, mine went out and then came back on when I got to the dealership. They found a code that was stored stating their was a problem even though it was working at the time.

 

I brought it. They said they didnt find any codes.

 

I've had the head unit replaced on the first visit and the command computer on the next visit when it went out again. The second time the screen went black and then came back on. When I drove the car into service, the tech said they found a code (I guess via Bluetooth) prior to hooking anything up to the car. Just my luck, yesterday the bottom half of the screen got fuzzy and then it went out completely (again), but came back on in a few seconds and went through the start up (AMG logo) and worked the rest of the way home.
I'm really getting fed up with this POS. I haven't even made my first payment and it will be making it's 5th trip to the dealer for issues. I should have just bought another Porsche!
