“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.”

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. …”
