My wife drives a 2003 325CI and was rear ended several months ago. After 2 months in the shop and over $11K of repairs we got the car back. But now it seems to be suffering a multitude of problems. The door lock doesn't work, the windshield wiper sprayer doesn't function, the radio just died, the newly replaced battery had to be replaced again (bad cell). Now the dealership wants $920 to replace the alternator. Since the battery is in the trunk on the right hand side, could the crash (which destroyed the battery), have caused a surge in the electrical system that is causing all these issues? I am fighting with the insurance company to have these items repaired. Any help or guidance would be greatly appreciated.
