I purchased my GXP for my birthday in July of 2005. My car is not even 2 years old yet and I have had major problems with it. I love the car, but hate the problems. I have had horn problems (not working), electrical problems(all lights,windows, and seats not working), and the worst, most unbelievable problem of all, I have already had (1) new transmission and (2) rebuilt transmissions in less than 1 year. i am trying to get GM to take it back and give me another car, but I am not getting anywhere with them. My trouble is that I have 48000 miles on the car. I am under the years but over the mileage. But I don't think it should matter considering I got my first new tranmission at 22971. Oh and I failed to bring up that the throttle body was replaced at 22900. I need help! Does anyone have any suggestions? I just want a GXP that actually works properly. I LOVE my car!
