I have a Scion Tc 08 and I had to different shops tell me that my motor mounts are broken and breaking. I've taking it to 2 different toyota dealers also and they both tell me nothing is wrong with it. It rattles when I'm stopped with my foot on the break and in R but not in N. I'm at 52,000 miles and the warranty ends at 60,000. I think there are doing me dirty. What is the next step to take??
