I was changing lanes and went to accelerate when the vehicle completely lost power. The cause of the loss of power is a plastic(yes plastic) rod that opens the intake to initiate turbo boost. The fact that his rod is made of plastic that can break so easily when you step on the gas pedal is dangerous. Mercedes benz is supposed to make a quality car that is very costly and it is shameful that it is made so shoddy creating a false sense of safety and quality. I am lucky to be alive and now have to fix this junk.

The wiring in the trunk that goes to the rear brake and license plate lights failed and opens the trunk failed. It was not possible to open the trunk with the remote or the button in the car. The only way was to use the valet key. There was also a warning in the dash about all of these lights being out. I took the car to a repair shop and they found the ground wire in the wiring harness between the trunk liner and the trunk lid had broken due to excessive wear.

Dear officer, from the beginning (2010 august, 0 mileage, mb e320) the car has a chemical smell. At first, I thought it will go away. However, in few months it became the most awful chemical smell (it is not mold, diesel fuel or exhaust). This extremely penetrating chemical(s) is/are coming from carpet. Venting/air-recirculation increases chemical concentration in the compartment to extreme levels. The chemical(s) is/are definitively toxic give strong headache, dizziness, cause nausea, vomiting, light-headedness, cause and activate asthma (personal complains) and other problems (google search). Deterioration components of synthetic organic compounds are known inducers of carcinogenesis. I will be happy to provide additional information on health issues. Based on google search chemicals in the car compartment are common problems of mercedes, volkswagen and bmw. The dealership rep agreed wit chemical smell. They offer chemical/deodorizer treatment what I am hesitant to accept as chemical odor reappear in few weeks (google search). Also many chemical deodorizer' are toxic (u.s. Environmental protection agency and the consumer product safety commission). Based on google search the sound proofing under the carpet is the source as it decompose in these vehicles and release the toxic chemical. Dealership agrees the source of chemicals but they do not agree to change sound proofing (although they admit this common problem in mercedes). I respectfully ask the federal safety agency at u s department of transportation to investigate this health issue caused by decomposition of sound proofing. This is an issue that severely effecting safety of driving and importantly well-being of us citizens. Sincerely, on behalf of many us citizens.
