Need help with C63S Issue

What's going on guys,

I need to pick your brain if possible, I've done research, but they've been inconclusive.
So a few months ago I purchased a 2017 C63S AMG and I've been having real issues with the car since then.

It's the 4th time in about 2 months that I need to have the car towed because of issues the dealer categorized as sensor problems, yet don't fix anything.
When I drive, sometimes the car will randomly starts to jerk, struggle to accelerate until it ends up completely stalling/shutting off and then won't start or do anything as long as the check engine light is on. When brought to the dealer, they just erase the code and brush it off.
It's starting to be a real pain as everytime it's a fight with the dealer to have the towing refunded, I'm literally thinking about dumping the car at this point because I'm afraid of driving it sinceI don't want to end up stuck on the side of the road.
Anyone heard of the issue? Any hint would be very appreciated

Def. sounds intermittent short to ground to me. I had a similar problem with my GTR. You need to find a decent tech. to dig in and fix this thing. I got lucky.

First thing I'd do is determine the code that's causing the CEL to turn on. Hopefully your service records will show the code, but if not you can scan it yourself. You can either scan it at a local auto parts store for free or invest in a cheap OBD2 scanner to check the code if your stranded like you described. If your dealer cleared the code, you're going to have to wait until the next time it comes on to scan it.

Knowing what code the car it throwing is central to figuring out your issue.
