Noises coming from underneath the SUV, check engine light constantly came on and one night I was going around 55 mph my 15 yr old daughter, we heard a loud pop it sound like we had hit something in the road so I stop to see what it was, we saw nothing but the squeaking sound from under the SUV got louder some day later jumped in the car started the car and there was that loud sound again only this time the SUV would not move in reverse I could hear some spinning like noise so I took it to a shop and I was told that the transmission was striped out in reverse, and that some shaft had broken or something, the mechanic also told me that he had several people come in with the same problem the same model Trailblazer 2002 what hurt me so bad is this was my first brand new car, I only had it for two years, and if I every buy another car it want be from GM, I also had problems with my tailgate lamps, windshield wipers, steering column.
