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.
