| Since the purchase of my vehicle, there have been multiple issues with the vehicle 7-8 issues, one selling point was the onsatr cellular service, never worked, etc. etc. etc. the salient matter at this time is that the drive train orginally exhibited a clincking sound shifting from 2nd-3rd and from 3rd-2nd, the noise was sporadic and went from a clincking to a decirnable clunk all the time, the dealer has attempted multiple repairs and now states the matter is a concern but it is not a problem, the oem, gmc, has states that ther is nothing they can do, the problem is getting worse and i am running out of options, i can not sell it as is. *jb | |||

| 2004 gmc sierra sle w/trailer towing package, 2-wheel drive. 2nd owner. never used to tow whatsoever. extremely well cared for. 59,665 miles. started making roaring noise from read end. called gm to ascertain if help for problem available. they told me to take it to lawrence-hall, abilene, texas for evaluation. lawrence hall says bearing in differential has failed. gm refuses to help in any way whatsoever with the repair, and even says that i am liable for the cost of the evaluation, even though they are the ones who told me to take it there, and even though they never said that they would not pay for it. when they told me to take it there, they implied that they would pay for the evaluation. i contend that at 59,000 that bearing should never have failed; that millions of vehicles go 2, 3 and 4 times that distance and never have that problem, and that had this locked up, it could have caused death and injury to driver, passenger and others. also contend that gm should have told me that if they declined to pay for the repair, that i would be liable for the diagnostic charge. when i dropped the vehicle off, the service manager told me 3 times that the courtesy vehicle is out there waiting for you, implying for me to hurry up and get out there, but then, as i was on my way out the door, brought me a clipboard and told me to fill in my contact info so we can get a hold of you. i handed it back to him, and he said i needed to sign it to give them permission to work on it. because he had been rushing me, i signed it and walked out. now it appears that they think that since i signed that form that i acknowledge to them that i am liable for the cost of the repair. *tr | |||
