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.

2003 GMC Yukon Owner Comments

problem #2

Mar 082006

Yukon SLT 5.3L

  • Automatic transmission
  • 50,000 miles


The AC would blow warm from time to time. We took it to the GMC dealer who stated everything checks out fine. Must be a glitch. Well, it has happened several times subsequently, and can be very annoying when it is hot and humid outdoors. Of course, it never acts up while it is Winter time in Florida -- the time when one is least likely to choose AC. In all fairness to GMC as a corporation, the problem has not reoccurred in a couple years. I just wnted others to know about a past problem. Mileage is now 139,000.
