Engine And Engine Cooling Problems of Mercedes Benz SL550

I was driving on a country road when all of a sudden my car lost power all the warning lights camo on the dashboard. Smoke started billowing out from the back and front of the car. It turned off and I only coasted about a 100 feet. I could not safely pull off to the side of the road as the car had no power. Thankfully the road was not very busy and the tow truck collected the vehicle. Upon further inspection I saw a lot of oil on the road and the mechanics were able to confirm that the engine block was cracked and there were 2 large holes. Upon further research I was able to find a lot of similar cases with this specific m278 mercedes engine and premature failures that happen because of bad cylinder coating. In later engines they update the cylinder lining to a more durable steel sleeves. I think this is a very well documted issue and a huge safety risk. There is a class action lawsuit running about the m278 engine and I think you need to get involved and hold mercedes accountable for their poor design.

Cam sensor seals failed which leaked oil into the wire harness, O2 sensors, and ecm. This happens to be a common problem with m278 engine. The repair was $10,217 to fix this issue. The car would not pass emissions without this repair. Could oil into the electrical system pose a fire hazzard?.

The car suddenly slow down in highway goes to limp mode for example from 69 to 35 miles is very dangerous I have to get off the highway.

On July 10, 2015 during 5 pm traffic my wife was making a left turn from the turning lane into our complex where we live, upon making her left turn, she had to cross two lanes of traffic, both lanes had stopped to allow her through safely, as she was clearing the second lane looking as she progressed, no one was in the outer lane turning into our complex, a man pulled out of line and attempted to allude traffic by going around it and struck her car in the passenger door, he never hit his brakes to stop and was attempting to drive through a turning lane which enters our complex only, there is a sign stating that this lane is for entering the complex and has markings on the road that shows where the lane begins further past our turn in entrance, instead he was going to drive over the markings to avoid waiting in traffic. My wife's car was hit hard enough to break both motor mounts and cause the roll bars to pop up, but the airbag never deployed, the other driver's bags all deployed up front in his vehicle.
