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.

2004 Chevrolet Trailblazer EXT Owner Comments

problem #1

Trailblazer EXT LS 4.2L

  • Automatic transmission
  • 118,000 miles


My 2004 Chevy Trailblazer Ext has such terrible fumes in the cabin of my truck that I would feel nauseous and have a headache after driving 15 miles to work. I took it to my local mechanic to have it checked out. I mentioned a bad smell inside and outside my vehicle to the mechanic. He came out of his shop and walked around my vehicle and said this is not an exhaust smell as I suspected, but the smell of gas. He looked over my vehicle and said that my fuel regulator switch had a big gas leak. He replaced my fuel regulator switch and I had no further fumes in the cabin of my vehicle.
