Unknown Or Other problem #1

Cable harness and connectors in steering cloumn airbag, poor connection from using steering wheel. Engine and transmission mounts disintegrated and needed to be replaced. Front thrust arms with bushings had torn boots and needed to be replaced. Crankshaft sensor was faulty and needed to be replaced. Transmission data link connector was faulty and needed to be replaced.

Unknown Or Other problem #2

2004 E320 4matic wagon. Engine stalled while merging to I-65 sb. Vehicle was 7qt low on oil. Vehicle was not equipped with a manual dipstick to check oil. Vehicle is equipped with flexible service system that monitors oil level, conductivity, temp, pressure. Owners manual shows that if any parameters are outside normal, or in the case of sensor/system failure, a red warning would appear on instrument cluster to instruct the driver to stop the vehicle and turn off the engine. No warning was displayed. Dealership states instrument cluster failed to communicate with central computer due to a software issue. Engine must be replaced. Requested Mercedes Benz to replace engine and assign engineering team to address issue and issue a service campaign to prevent failure from happening to others. Mercedes benz stated that they will provide no assistance. I am concerned that this issue could also fail to provide other important information (brake system, airbags, engine cooling paramaters) as well. As an engineer, in my opnion, this is clearly a design flaw that needs to be addressed and should have been evaluated by a failure mode effects analysis prior to deciding to remove the manual dipstick. If instrument cluster could not communicate with central computer, it should display a warning to stop the vehicle.

Unknown Or Other problem #3

Unknown Or Other problem #4

My 2004 Mercedes Benz e-320 began emitting a strong odor of gasoline in 2010 and was taken to the local dealership (schumacher mercedes in scottsdale, arizona) for inspection when it was determined that there was a leak in the fuel tank and that it needed to be replaced along with the left sender pressure sensor and tank fittings. The vehicle had approximately 60,000 miles at this time and was outside of the initial warranty so the $2,500 repair was undertaken. Approximately 2 years later and 40,000 miles later, the same symptoms returned and the vehicle was taken back to the same dealership for inspection. It was determined once again that the same problem was occurring and the fuel level sensors were leaking fuel and needed to be replaced again. The cost for this repair was estimated to be $1,200 and this time the repair was rejected. The service advisor at the dealership claimed this is a common problem with these cars and there was nothing they could do about it. The vehicle had always been maintained by the dealership since the beginning and apparently there have been no recalls issued that we were aware of for these malfunctions and defects. I have contacted mercedes corporate office and they opened up an investigation only to determine that the dealership acknowledged the problem with the vehicles but neither party was willing to accept responsibility for the defect and no additional assistance would be available or commissioned for me. This is a major safety issue and should not be considered a common issue or routine maintenance for any car, let alone a Mercedes Benz. If something does not get rectified with this epidemic malfunction of these vehicles, it could lead to a major accident or even death.

Unknown Or Other problem #6

Contact stated when stepping on the accelerator pedal the vehicle will not accelerate. This caused a safety concern because while merging into traffic the vehicle failed to accelerate. This only occurred when the vehicle is stopped or was close to stopping. The majority of the time it happened when the vehicle was started up. There was no indication as to when this will occur. It happened approximately 30 times. The service dealer attempted to repair the vehicle once, but because it happened periodically they could not duplicate the problem. The manufacturer refused to service the vehicle. Consumer felt the problem with the vehicle could be the drive- by -wire or computer system. The right rear brake locked up while the consumer was making a right turn. This occurred after the brake had been reprogrammed. On cold morning the gps did not work properly. The leather on the driver's side air bag was peeling. The tire pressure monitoring system had to be reprogrammed. The front wheel bearing had play in it. The rear alignment was off slightly which caused the vehicle to shimmy while driving above 62 mph. On August 22, 2005 while driving a loaner Mercedes Benz e350 from the dealer the consumer experienced the same intermittent hesitation on acceleration as he had with his own 2004 e350. The consumer believes this hesitation problem is not isolated to vehicle.
