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.

Yukon SLT 5.3L V8

  • Automatic transmission
  • 28 miles

This model year Yukon is terrible. Many, many problems. Electrical & mechanical. I have more than $8,000.00 in repairs to date. Some were pr-existing conditions the dealer wiggled out of during the warranty period. I have another $3,800.00 in repairs that are still needed. The transmission went out at under 80,000 miles (this is a weekend car by the way), the front differential needs to be repaired as well as the front seat memory module. I will not buy another new GM in the future. Not just because the vehicle is garbage. Because how GM made it my problem & not taking steps to properly repair it.

Yukon Denalli 6.0L

I HAVE AN ELECTRICAL DRAW ON MY 2003 YUKON DENALLI. I HAVE REPLACED THE BATTERY TWICE AND THE ALTERNATOR IS GOOD. I HAVE PULLED EVERY FUSE THAT HAS POWER TO IT AND THE DRAW IS STILL THERE ACCORDING TO MY VOLT METER. IVE CHECKED ALL THE EXTERIOR LIGHTS AND DOOR BUZZERS AND NOTHING SEEMS TO BE ON IN THE VEHICLE AS FAR AS ACCESSORIES THAT I CAN TELL.
