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.

Print this page 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.

Transmission failure. I own a 2003 Trailblazer and have had numerous problems with it. They have replaced 4 fan clutches, 3 computers, transmission just had its 2nd overhaul and numerous other little items. This vehicle only has 66,400 miles on it and I bought it brand new.

problem #1

  • Automatic transmission
  • miles
: the contact stated the instrument panel did not function properly. The speedometer indicated 30 mph while the vehicle was parked. Also, the tachometer, the oil and fuel gauges, and the odometer did not give a reading at all. The fuses were removed and put back in, which only corrected the problem temporarily. The vehicle was taken to a private repair shop, where the mechanic was unable to determine the problem.
