I have a 2009 GTS and last night as I drove to the gym I noticed a knocking sound coming from the rear drivers side. The sound is rotational and sometimes gets worse with braking. On the way back I noticed that it started to turn into a grinding type of noise. It only happens under 10-15 mph. I tried to run it to the dealership today but they have no openings until tomorrow. It sounds terrible today. Has anyone else experienced something like this? I'm guessing it's something loose, maybe something with the brakes? I really have no idea.

 

admin you can close this thread. I got it all figured out, and the car is fine
