I didn't have my car 6 months and the brakes started making a very high pitched squealing noise. It occurred every single time you were in reverse. Some times the breaks would work and the car would stop but sometimes it wouldn't. I took the car to the dodge house and they told me I must have dirt on them, because that's the only reason they would do that. After having my car a week, they tell me they took the breaks apart and there was no dirt so they put them back on the car. I still have no clue what is causing this problem.
