“While I was driving the car, with the seat belt fastened, the seat belt suddenly popped out. This was a scary experience! Repeated attempts to fasten the seat belt again did not work. On closer inspection, it appears that something inside the fastening system was probably broken, and the seat belt wasn't getting fastened in there. I immediately took the car to the dealer (Mercedes Benz of El Dorado Hills). After inspecting it, they were able to reproduce the issue (seat belt not getting fastened at all) and advised replacing the seatbelt system on the car. …”
