NHTSA Complaint #11450360 — 2015 MERCEDES-BENZ C300

Car has 51,000 miles , no check engine light or any other warning light .driving in on the freeway at 70 mph when I hear a pop sound and my car loses power , I pushed on the gas and it started to shake violently and I panicked as the construction on the freeway was not allowing drivers a shoulder to pull over on . I was lucky enough to be driving at 2am and with the construction going on , drivers were already slowing down . My car also started blowing a thick white smoke through the back exhaust that could have made it harder to see that late night as it was already foggy here in California . At first I didn’t realize I was smoking through the back until my car began smelling like burnt oil . I wasn’t able to get off the freeway until the next exit all while thinking that my car was going to explode from the smell of the burning oil . When I pulled over and got out of the car I made sure I didn’t see any fire and then I waited to let it cool down , opened the hood and saw oil everywhere . I had it towed to Mercedes and I got the problem and the estimated cost to repair it . The problem turned out being a cracked piston in cylinder one , when it cracked it allowed oil to mix with the gasoline and that’s what was causing all the white smoke out the rear , the burnt smell was from the oil that was leaked all over my engine getting too hot from the engine. I found out a few days ago that Mercedes’ has a technical billeting regarding a faulty wrist pin that was causing the pistons to eventually crack . In the bulletin the faulty pin problem is fixed by replacing all the pistons and adding a upgraded pin and many other parts . So there are many other drivers that are experiencing this and driving with faulty wrist pins . Prior to all this happening the car always made a tap tap tap sound from engine and Mercedes’ said it was normal for 4cylinder turbos to make this sound, sounded like a diesel . But it turned out being from the loose wrist pin . Mercedes lied to us . THE CONSUMER REQUESTED THAT MERCEDES BENZ VEHICLE
