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.

2003 Chevrolet Trailblazer Owner Comments

problem #3

Jun 012004

Trailblazer LS 4.2L I6

  • Automatic transmission
  • 10,000 miles


Strange knocking noise going over small bumps. Most noticeable if I am turning right when going over small bumps with left front wheel. Also noticeable, but less so, when going straight over several small bumps in a row.

(reported on)

Trailblazer LT In Line 6 cyl

  • Automatic transmission
  • 35,000 miles

Rattling noise started when the vehicle had approx. 35,000 miles on it and got progressively worse over time. When I brought the vehicle back to the dealer that I bought it from for new tires in Oct. 2007 I asked them to check what might be causing the rattle. The vehicle had 50,000 miles on it. No trailer pulling and 99% highway miles. One ride around the block on city streets I was informed that my stabilizing link bushings were bad and should be replaced as over time they will continue to wear and cause a handling problem. The links were around $350 and labor was $100. The service guy did inform me that this has been a common problem with this vehicle. Called a couple of other Chev dealers and was told the same thing. Having owned GM vehicles all of my life I was really pissed off as my other vehicles usually made it beyond the 50,000 mile marker before I encountered major out of pocket expenses. I then sent a copy of of my bill from the dealer to the GM consumer center as I was concerned that these parts should not have failed at this point in time on a fully loaded very expensive Chevrolet Trailblazer. I was hoping for GM to at least admit that there was a problem and buy me a cup of coffee if nothing else. I did get a call from them and after a total of 59 minutes on my cell phone and two service reps latter I was told that they failed because of normal wear and tough sh*t but the replacement parts would have a one year warranty one them which does me alot of good since they will not fail until 35,000 again. I could not get any assurance that the replacement part was any better than the ones taken off. GM did involve the dealer in the process, 2 times and still no luck on getting any help on this repair. Can you imagine in this day and age a rubber suspension part failing and GM claiming due to normal wear and tear. Wow.
