Failure Date: 11/17/2011

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.

Engine and engine cooling:engine the drive belt pulley on the engine is develop fatigue cracks in the metal and break. The drive pulley breaks, the car would not have engine cooling, battery charging, and/or power steering. Consequence: loss of these systems can cause the car to over heat, lose power from the battery, and loss of control of the car increasing the potential for a vehicle accident I took it to the dealership, and they said that there is no recall on the car and they can not help me so nothing was done to correct the failure.

Failure Date: 06/10/2005

Crank position sensor (cps) started to fail when the outside temperature was above 95f. Car (1999 Mercedes Benz E320) failed to start twice when parked after driving for a short distance. Only after cooling it would start again. At one point the engine became very erratic while in traffic. At another point I was stopped on the traffic light and the engine just stopped running. Fortunately I was near home and after waiting a few minutes it started again. It was embarrassing to say the least , having a mb car stall in front of other much cheaper cars on the traffic light. Fortunately, I was using this car for only short trips and did not incur the risk of having it stall on a highway, but I am sure it would as long as the engine temperature was above a certain point. .
