2006 Mercedes-Benz ML350 Owner Comments

problem #5

ML350 6-cyl

  • 93,200 miles


The vehicle is getting stuck in 7 gear on the freeway and not down-shifting to allow passing. Even when coming to a stop, the car will remain in 7th gear. This is a dangerous condition because the consumer does not know the car is not shifting correctly. Mercedes is aware of valvebody and conductor plate issues with these cars.

While traveling in the center lane on a major parkway at the posted speed limit, our 2006 Mercedes-Benz ML350 experienced a complete engine failure. The car would not accelerate; steering was compromised, as was braking. Braking and steering were very difficult, but possible allowing the car to be guided to the shoulder. All four family members were present including our two young sons. After being towed to a local authorized dealer repair shop, 4 days after the incident...the problem was reported as "engine jumped time? and the repair department would have to ?remove engine and tear down to find cause of failure?most likely needs engine assembly?. as that the quoted price of the diagnostics and repair exceeds the current value of the car by several thousand dollars, the car was returned without further diagnostics or repairs. At no time in the past 4 years has there been a ?check engine? light nor were there any indicators of any serious mechanical issues as per the car?S onboard computer reporting system or in general daily operations. Again, it is important to note, that there were no indicator lights or warnings prior to the failure. It is also important to note that in January of 2010, the same authorized dealer repair department mentioned above conducted the following repairs: ?removed engine, replaced balance shaft, replaced oil pump, replaced cam solenoids, replaced gaskets?? in response to a persistent ?check engine? light. Our records indicate that the 2010 ?check engine light? occurred at 55,395 miles. This recent failure has occurred, minus the ?check engine light" or any other indicators, at 99,424 miles. Our research indicates that this may be a known issue with this particular engine.

The consumer owns a 2006 Mercedes ML350. When she purchased the vehicle the motor raced when it was started. The vehicle lurched forward when her foot was first taken off the brake. On August 9, 2005 the consumer was pulling into the garage with her foot on the brake and the vehicle surged forward. She stated she could hear the motor surging. She pushed the brake pedal all the way to the floorboard and the vehicle did not stop. The vehicle pushed a ping pong table through the wall and then stopped. This caused $5000 damage to the garage and $4000 damage to the vehicle. When she took the vehicle to the dealership they stated there was nothing wrong with the vehicle and she may have hit the accelerator.
