“Timing chain on the vehicle stretches out over time. This causes the vehicle to not start properly and can snap while driving and stop the car in the middle of traffic and driving. There is no service recommendation for the timing chain and usually starts giving trouble after the vehicle's warranty has expired. I have not had my car stop in traffic but there are many complaints on the mercedes benz forums.”

NHTSA complaint #11354633, filed 2020-09, 85,000 miles“I have been having issues with my vehicle since I purchased it. Starting with me not having enough power from a start, in an attempt to gain enough power to drive at a safe speed from the start, as if the vehicle lags & no matter the gasoline or service, the problem never corrects. When I'm trying to gain speed to maintain with the flow of traffic safely the vehicle lags notably before gaining speed. I'm now having to replace the engine bc the oil coolant hose burst while I was driving on the highway with my child in the car. …”
NHTSA complaint #11385548, filed 2020-12, 117,000 miles“I was driving a of maybe ten minutes on the highway . As soon as I was off the highway ; the vehicle suddenly stopped without warning of a check engine light .(malfunction). Days before that the vehicle was serviced at a mercedes benz dealership without any issues. After their research I've been told that I need a new engine . There are complaints after complaints listed online in regards to engine failure, cam shaft adjusters etc. This is something that clearly needs to be handled . This could have caused a life threatening situation.”
NHTSA complaint #11350193, filed 2020-08, 100,000 miles“I bought the certified car at 50k and at 70k miles, right after the warranty ended - check engine light came on and the dealership said it will cost $8k due to camshafts to repair!! They even suggested that I should consider trading the car in! Keep in mind I still owe $28k so that option is out! Since then the check engine light still on even after I got it repaired at a local/affordable mechanic and it's about 110k mileage and the engine is rattling as it runs. This is my 3rd benz and the first 2 failed due to the transmission failure. …”
