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.

CarComplaints.com 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.

For approx. 4 months I would go to get into my Trailblazer and the vehicle would be dead. Would not start unless I had it jumped. It would go 2 weeks with no problem then out of the blue, not work. I had the battery changed 2 times, alternator, starter checked with no problem. Finally after the last time, I had the alternator people come and get it and they checked it out for 2 days. The ABS system is what came up. I had to have it taken to the dealer that I purchased it from (I have only had this vehicle purchased used for a year and couple of months-vehicle is only 4 years old now) and it is the ABS module costing me $1150 to be fixed. Dealer states that it stays on after vehicle is turned off and running my battery.
