I have been sent a pretty egregious recall by gm. i made an appointment with the dealer i purchased the car from. dealership told me they had to order the part. it's been a month. when i went to the dealership, they said the part was not in. meanwhile, my friend had her recall fixed there. this is regarding a joint in one or both front lower control arms that can separate your tires from the vehicle. pretty scary, but i am getting nowhere with the chevrolet people. i call every day. how can you help me ?
