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.

I was pulling out of my driveway when all of a sudden, the car came to a screeching halt and would not move. I was stuck diagonally in the middle of the road. When I called AAA for a tow they said it looked like the passenger front ball joint failed. Upon inspection, it was found that the ball joint failed and the tie rod, lower control arm, and strut all broke as a result. The axel was also ripped out when the control arm failed. All of these things needed to be replaced. I can only image what would have happened if I had been traveling on a main road or highway at a higher rate of speed. But to have a catastrophic failure like this happen was completely unexpected, especially after having brand new tires and an alignment completed only one week earlier. Ultimately, I am unsure if this was due to an error on the tire shop's part with the alignment they did or a Mercedes general quality issue. Either way, my vehicle is inoperable and I'm faced with a $1,700 bill for what should potentially be a recall. To know that another one could fail at any time at any speed with no warning is deeply unsettling and I will be getting rid of the car as soon as possible, likely never buying a Mercedes again.
