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 Avalanche Owner Comments

problem #1

Feb 152006

Avalanche 8-cyl

  • Automatic transmission
  • 55,000 miles


2003 chevorlet Avalanche 1500 - drive shaft universals failed (front gone, rear going. I had dealer replace both) - I noticed the noise and immediately took vehicle in. Had I not noticed or could not pinpoint the cause I may have continued driving and it could have failed and failing while driving on the thruway would not have been a good thing as the front end of the driveshaft impacts the road. My concern is that when talking with GM customer service on more than one occasion the folks with whom I talked could not say whether GM had a data base on the average/mean failure time on the universals. I wanted to determine should I start concerning myself as I get to 100,000 miles, but they were unable to assist me. So I am writing you if you have had other universal failures around 50,000 miles.
