I first noticed an issue with the alignment. The vehicle would always pull to the left. After 3 different alignment procedures, it remind the same. I started noticing a clunking sound when I would brake. While driving I hit a moderate pothole and the car lurched side to side, causing me to lose control. It was fortunate that I was on a surface street, and that I was only traveling about 35 mph. I almost struck the vehicle next to me, but my quick reflex prevented it. I limped the car, going 15-20 mph with hazards on, to my mechanic. He called me the next day informing me that I had a complete rear subframe failure. I researched and found that Mercedes, had extended the warranty on all models of the same year but my model was not included. Numerous mercedes of the same year and model are having the same issue. This is an EXTREMELY and dangerous issue that Mercedes need to address. Others my not be so fortunate as I was to have been on a surface road under speed. I would not have been able to control the vehicle had I been traveling at highway speed.
