I love my car .
My husband has a 2006 my friend has a 2007 and another friend has a 2008.
I was backing up and this loud squeeking sound came from my car, my husband was with me and said his car does the same thing, I had my breaks checked and the pads are fine . I was leaving work one day and it happened again and a co worker who owns a tc came out to stop me and said her car does the same thing, Where I live is an aparment complex and I could not beleive it a girl that drives a tc was backing up and her car did the same thing I stopped her and she said it started out of the blue , This only happens when you back it up . This should be looked into i think it is a manufacture issue
