Example complaints

Fuel system: “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.”

NHTSA complaint #10654777, filed 2014-11, 59,600 miles

Engine: “The oil cooler on the vehicle is leaking oil. This is a large, 15 hour repair, the total estimate to replace the cooler and seals is $2350. I have not had this repair done yet. Also had other oil seals replaced in the turbo area of the engine which cost me $989.91.”

NHTSA complaint #10778933, filed 2015-10, 123,000 miles

Electrical system: “2 highway stallings: 1) dec.1. 2009 traveling on I-95 south at 70mph, check engine light on, car suddenly stalled, managed to pull to shoulder. Car towed to benz dealer 90 miles away. They changed a new fuel pump in charleston, sc. Continued driving on 2) dec.3,2009, after 400+ miles on I-95 south at 70mph, check engine light on, car suddenly stalled again, managed to pull to shoulder. Car towed to benz dealer in melbourne, florida. They changed another fuel pump and filter. Now I am driving with my finger crossed.”

NHTSA complaint #10296303, filed 2009-12, 2,302 miles

Engine cooling: “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. …”
