“I was driving the car and just stop in the middle of the street, I almost had and accident. I took my car to my mechanic, he can't fixed, the dealer need to do the job for tree times more. Than my mechanic. This is unfair! I buy my car in 2012 original mileage 10000miles. To my knowledge is to low very mileage for having this type a problem.”
NHTSA complaint #10713388, filed 2015-04, 24,000 miles“I have 2010 mercedes benz C300, my car would not start with my key even though the battery checked okay. This is a very common failure among C300 models (2008 to 2013). So meaning cars are vulnerable to this failure around 5 year mark. Manufacturer should issue a recall on these parts, as they have a very bad reliability.”
NHTSA complaint #10749702, filed 2015-08, 68,000 miles“After backing out of handicap parking space and moving forward at a slow speed my vehicle was rear-ended, at which point the vehicle forcefully accelerated forward independently without warning and crashed into another parked vehicle (forcefully moving this vehicle approximately three feet) the vehicle continued to speed through the handicap parking lot as I continued to brake without results of stopping. …”
NHTSA complaint #10863485, filed 2016-05, 63,000 miles“Luckily I took car in for a safety check and belt tensioner was found to be shredding. It should last longer than this and is a safety hazard. This extra visit to the dealer may have save me from having an incident. I otherwise never would've know the belt was shredding.”
NHTSA complaint #10715252, filed 2015-05, 65,000 miles“The check engine light comes on dealing with the catalytic converter/fuel system. The sensors are off causing the emission of too much gas. The car runs out of gas fast and does not drive well to get good gas miles per tank. The car's exterior lights also go out fast. This should not happen with a top of the line mercedes car.”
