I must place the car in Park and then Drive again in order for it to move forward. I have brought this up with Mercedes multiple times and eventually had the transmission replaced. 2 days later, the same thing happened. They do not have a repair available …

Owner report 11729030 · 2026-04-03 (April 3, 2026)
Car stops accelerating and shifts into neutral without warning I nearly got hit from behind. I have consulted several other Mercedes vehicle owners and all had the same issue. Two of the other owners stated that this happened on the interstate and was very lucky they were not involved in a collision. Both vehicles were GLC 300. Mercedes does not seem to have an answer to the issue and all previous owners traded vehicles for fear of dying.
