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. Notes: Carrying the not-so-proud traditions of its 2002 predecessor, the 2003 has a handful of instrument panel malfunctions that can leave you guessing your speed, engine temperature or how much gas is left in the tank.

problem #11

Trailblazer 4WD 6-cyl

  • 65,000 miles


2003 Chevy trail Blazer. Noticed very odd wear pattern on front tires. Front end of car seemed "loose". no accident, car just hard to steer accurately. Took to dealer. Both front lower ball joints were loose. Front struts were shot. Dealer replaced lower ball joints and struts. I'm a little old lady who drives in town - only 65,000 original miles and front end is going out. Pour quality! dealer said front end worn because car has 4 wheel drive and is heavier than passenger car. I do not drive off road. Repairs not covered by warranty. No help on 60,000 mile front tires completely shot in 17,000.

I was backing out of my driveway and the driver side control arm snapped on my 2003 Chevy Trailblazer ltz. The consequences could have been fatal if it happened 2 days prior while I was driving out of town on the freeway going 70 mph. A new control arm has to be installed. I have the dealer saving the old parts including the bolt. I found the bolt head at the end of my driveway.

I have a trail Blazer, Chevrolet 2003 for which I have had to change the bushings/links over 6-7 times. The part in reference is made in a material "calamine""?" which is not a metal and breaks easily. There is not a campaign on that part, yet I know several trail Blazer owners that have had the same problem. The links in the rear suspension came out in iron or some type of metal. I am totally frustrated because my vehicle is not longer under warranty.

Complaint received via E-mail. My son was driving car at 45 mph, when all of a sudden the rear end came loose. This made him lose control of the vehicle and crash. The vehicle was totaled. My son had minor injuries. His initial statement to the deputy was, the vehicle felt like the rear end came loose. The deputy looked under my SUV, and found the sway bar with a clean break on it. He then proceeded to have someone else look at it also. They both stated there was no twisting or distortion of the sway bar. It appeared the sway bar just broke.. rear sway bar was replaced.
