Failure Date: 03/15/2005

On 3/15/05 the new gto oil pump failed. Returned to dealer on 3/16/05. On 4/07/05 the car was returned to us and we were told it was perfect!the next day 4/08/05 the car was returned to the dealer. The car was repaired that day, and we were told it was now fixed!!! two [2] days later on 4/11/05 the car was again returned to the dealer. The car is still at the dealer, it is not fixed, it is a piece of used and repaired , broken car. We paid for a new 4oo hp gto, and now after all this agony have had to pay an attorney $4000. 00 to get this mess taken care of. This car on the first day of ownership had a problem with all the windows, execpt the windshield, a spotty and discoloring. This I reported that day. This is a joke, GMC will not help it's customers for any reason. The dealer, early on in this mess asked GMC to exchange cars for me, nope! they said it has to go thruogh the process. The process is a failure!!!! now I want my investment plus!!! your costomer service is a joke!! I was guaranteed answers to my questions and promised a call back and it never happened!!! one gentleman mr. Jarret, said " I will call you in 10 [ten] days . So I can get to the bottom of this. May fisrt was 10 [ten] days. I had to contact mr. Rick wagoner's office 7 [seven] times before mr. Jarret retuned his promised call! I can go on and on with documation about the wat this was mishandled. We wre treated as lairs. While the whole time it was GMC>.
