2008 Mercedes-Benz E-Class Power Train

The contact owns a 2008 Mercedes-Benz E350. The contact stated that while approaching a stop, she heard a roaring sound coming from the vehicle. The contact stated that the vehicle then stalled without warning. The vehicle failed to restart. No warning light was illuminated. The vehicle was towed to the dealer where it was diagnosed that the rear differential had failed and needed to be replaced. The vehicle was repaired. The manufacturer was not notified of the failure. The failure mileage was 71,888.

The vehicle will intermittently go into limp mode with a max speed of 45mph. At a stop vehicle will not accelerate FWD unless transmission is put into park and the vehicle turned off and then re-started. Professional diagnosis suggests the transmission needs to be replaced and this is common for cars with 100k miles or more. Only a Mercedes Authorized Technician with a real time connection to a Mercedes Server can properly perform this task. This is a sub par design that creates a safety hazard. The repair procedure coupled with the frequency of this serious failure makes this vehicle a Lemon. Mercedes Benz Is Totally Responsible.

REAR DIFFERENTIAL NOISE DIAGNOSED AS FAILING PINION GEAR. THIS CAR HAS BEEN DRIVEN CAREFULLY. THE MILAGE IS 63,000. REAR DIFFERENTIAL PROBLEMS APPEAR IN VARIOUS FORUMS AND MAY OCCUR MORE COMMONLY THAN IS CURRENTLY KNOWN BY THE NHTSA. SIMILAR/SAME MAY ALSO BE OCCURRING IN CHRYSLER PRODUCTS. THE REAR DIFFERENTIAL WILL NEED A REBUILD OR REPLACEMENT.

THE TRANSMISSION IN MY CAR WILL INTERMITTENTLY SHIFT INTO LOW GEAR WHILE DIVING. THE CAR SUDDENLY LOOSES POWER WHILE AT HIGHWAY SPEED. THE CHECK ENGINE LIGHT CAME ON AND NOW THE TRANSMISSION WON'T SHIFT OUT OF FIRST GEAR. I'M TOLD BY THE MERCEDES-BENZ DEALER THAT THE TRANSMISSION MUST BE REPLACED AND I HAVE TO PAY FOR IT, $7000! THIS IS A SERIOUS SAFETY ISSUE AND I SHOULD NOT HAVE TO PAY FOR THEIR FAILURE. *TR
