20231116SERVICE BRAKES
I brought the car to my Mercedes dealer for a State required safety and emissions inspection. It passed but they said the rear brake line were rusted and needed replacement at a cost of $2546.00. This model and numerous others were recently provided an extended warranty for rusted subframes. This is a $5-$7K repair. They do not cover the brake lines or include them as part of the repair. The sub-frame rust from the inside out so it is not initially obvious of impending failure. There is a pending class action lawsuit against MBUSA that mentions the failure to include the brake line and other components. The rusted brake lines are indicative of internal rust of the subframe. I am facing potential brake failure if I don't act on this expensive repair when clearly Mercedes is not acting in good faith to repair the entirety of their faulty components.

Car looses communication with the Electronic Ignition System (keyless system) and while rolling to a stop light, slams the car into park while still rolling. It also will throw itself into park while first accelerating - almost causing the car following me to crash into my rear end.
