Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

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.
