The engine in these cars are defective and can cause serious harm due to a part that was put inside the motor made of plastic. There was a lawsuit but if you didnât get in on it you losses out for not knowing. I was recently at Mercedes dealership to fix recalls and they brushed me off. The car can catch fire and Iâm already experiencing engine failure after only owning the car for a year. They donât care because itâs an old car but itâs still being sold to unsuspecting buyers. Iâm not the only one there are thousands of us who are at risk driving these cars because Mercedes wonât admit their off the showroom floor mistake.
