“I brought my vehicle to mercedes benz for a rear tail light recall. When I picked up my vehicle the brake pedal went to the floor. Note: this was not happening prior to me dropping the car off to the dealer. The service manager drove my car back to the mechanic. I was then told that, ironically, the brake line rusted (metal line) out causing the brake fluid to leak out. Also, passenger front seat sensor went. Seat will not move back or forward.”
