My Mercedes 350 e has a tendency to cut off for no apparent reason, it recently had a tune up. It also did this once before the tune up. The thing I noticed is on blazen hot days this will occur, never cold. Could you please help, I have invested to much to throw the car away.
I would suggest that you take this vehicle to a certified shop or dealership to have it diagnosed. It's not safe to have the vehicle shutting off while you're driving.
You will probably have to leave it with them, and maybe for a couple days, until they can get the problem to happen. This will be the only way to diagnose the problem. Good luck.
