NHTSA Complaint #11508260 — 2016 MERCEDES-BENZ C300

I bought the car with 51k miles . Engine failed at 71k miles , due to piston #1 cracking . Almost caused me to get rear ended on a busy street . I went to the dealership and they charged me $10250 to replace the engine with a remanned long block and they offered a 2 year warranty. 9 months, only 19k miles on “new motor” the “new” engine fails again … same reason piston # 1 cracked failed suddenly on the highway and I had to push the car to safety to the emergency lane while cars where coming.. I went back to dealer demanding a replacement and told them this is a common occurrence and they refused to help me . I called corporate. They refused to help me saying I would have to purchase an engine for the second time out of pocket when it only lasted 9 months. This is a big fault in the m274 engine … it’s also a safety hazard that can cause serious injury, fire , or even a deadly accident. I read that it’s a common issue with these engines.
