Hello, I just got an A service done at mercedes only yesterday and also got brand new tires and an alignment. Today randomly after going forward from a red light and accelerating, my car jerked a few times. After that it didn’t happen again and then on an open road in my neighborhood I tried to see if I could trigger that reaction again and accelerated quickly and it happened again. I hope this makes sense, I’m not very car savvy and I plan on taking it back to Mercedes to see what is going on but that isn’t till Monday. Any idea what could be the issue? Could the service I got done on it be the cause? Any opinions are appreciated! Thanks
