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.

problem #2

Oct 012013

Sierra 2500 SLE 6.6L Diesel

  • Automatic transmission
  • 65,000 miles


GM claims that brake lines are failing due to lack of maintenance. Mechanic (GM Certified) told me that the metal couplers were catalyzing with the metal lines.....causing the lines to rust....inside out. So where in the maintenance manual does it say to inspect steel brake lines? This faulty design has already been reported - affects all 99-2002 1500/2500 frames. GM has skated by and the government will not lift a hand to find them guilty.

problem #1

Sierra 2500 V8

  • Automatic transmission
  • 80,000 miles

My brake line rusted out on the underside of my truck. My mechanic advised this should never have happen. He feels GMC used cheap materials. I have much older vehicles and I have never in my history of owning a vehicle had the brake line rust out under my vehicle. I almost had a serious accident because of this. I saw a similar problem on this site. GMC definitely should look into this matter and issue a recall. There could be serious injuries or lost of life due to this problem.
