My 2000 Honda Accord was rear-ended a few months ago. A month after it was fixed the alternator failed! 2 months later I heard wierd noises coming from the back & under the car--like metal being dragged over a rough surface. What's happening? I checked the underside; couldn't spot anything amiss. I'm not a car person, had bought the Honda because of its great reputation and now I'm really upset! It was always on time for its servicing etc. & in great shape. My questions--do you think it's related to the rear-ending? else what could be wrong? Thanks in advance for your help.
