I was having some problems with my parking assist feature. It wasn't working. I took it to the dealer to have it repaired under warranty. The dealer had it overnight. The next day they called and said they had to special order a part and I could take the car and use it in the meantime. I picked the car up and took it home. Later I noticed there was a very deep scratch shaped like a Z about 2 inches across near the seam between the front bumper and the fender on the driver side. It was obviously made when they removed or replaced the bumper. I complained and the service person said they would look into getting it fixed. What eventually happened is that the scratch is still there, but it's painted black and barely visible unless you look right at it. It is still visible. Since cars will get scratched even with the best of care when you take them out in the world, I'm wondering if I should be content with the "repairs" or try to get them to sand it out and repaint it.
