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 Chevrolet Suburban Owner Comments

problem #2

May 012010

Suburban LTS 5300 v8

  • Automatic transmission
  • 80,000 miles


Occurs intermittently. Never overheats. Pressure tested the system and found no leaks. No accumulation under car after parking. I'm totally bewildered!!

problem #1

Mar 092009

Suburban V8

  • Automatic transmission
  • 140,000 miles

I have to constantly use coolant every 2 weeks $17.89 and paid 258.00 to stop roaring noise and clicking sound when I turn and it still does it. I constantly smell gas, engine pressure problem etc

Update from Apr 26, 2011: I've replaced a motor with 85,000 miles and still continue to buy antifreeze since 2010 current now imagine spending over 30.00 a week depending on how much you drive it within that week
