I picked up a brand new 2025 mercedes glc on november 30th. On december 13th, i was driving through a tunnel with my 4 year old niece and my wife when i suddenly lost functionality of the gas pedal and the check engine light went on. I was able to hobble it out of the tunnel even though there was a long line of cars behind me. I was able to get the car towed to the dealership. The dealership inspected my car and advised me that there were bubbles in the fuel line which they have been seeing with multiple 2025 glc models. Mercedes corporate advised the dealership to empty the fuel line and re-fuel it, that a recall was going to be issued, and that mercedes corporate would be working on a permanent fix via software update to be released in q1 of 2025. I have tried to reach out to mercedes corporate but have not had any success.
