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.

  • 77,000 miles


Speedometer started fluctuating around 55K miles. Finally quit totally at 77K which was beyond my extended warranty. Don't have enough money to pay the 500 bucks to get it fixed with $4 a gallon gas. As smooth as the Trailblazer rides it is hard to tell how fast you are going, ,,,,,,,,,,certainly a safety hazard. GM should be covering this for life of car.

The instrument panel goes haywire when car in operation. The speedometer will not show correct speed. The tachometer will not operate at all. These problem are intermittent. I have not had the problem fixed because I am hoping this will be covered by a recall through GM.

  • Automatic transmission

The motors on the gauge cluster start to fail around 50K miles. Mine is failing right now with 51K miles causing a false reading on the speedometer. After a short time on the road the speedometer starts to lose speed with out lifting off the gas pedal. After a 1/2 hr on the road doing(atleast I think) 65mph it will read that I am doing only 20-30 mph..

I have a 2003 Chevy Trailblazer. My instrument cluster has stopped working. My speedometer, gas, oil, temp, and amps do not work. Chevy currently has a recall on other models for this problem, but not the Trailblazer. I feel Chevy need to take responsibility for all of their vehicles.

I have a 2003 Chevrolet Trailblazer ltz. There are "stepper motors" that run each gauge inside the gauge cluster. My speedometer stepper motor has gone bad causing me to not know what my speed is. I have seen this same problem on numerous message boards as well.

The speedometer on my 2003 Chevy Trailblazer went from 0 to 120 at a stop sign. Now it is stuck past the 120 and just vibrating. Sometimes it will go back to 120 but seemed to go right back to the dead space past 120. The Trailblazer only has 45,000 miles.

Shortly after the warranty expired on our trail Blazer, the speedometer started giving false readings or would quit working. We talked to the selling dealer and was told that the repair would cost about $500 dollars. To me this is a safety issue and should be repaired by General Motors at no cost to us. We have been told that GM is replacing speedometers on other models with the same problem.

The speedometer on my 2003 Trailblazer quit working. It displays a speed that is anywhere from 10 - 70 mph over what the actual speed is. The problem is due to a bad cluster of gauges.

When driving @ speeds over 60 mph, the speedometer would just keep going until the needle was pointing straight down. It would then stick at about 70 mph, and then each time you would turn the vehicle on, the speedometer would go down 5 mph, and eventually reset itself.

Instrument cluster stopped working properly. Speedometer would register various mph while vehicle stopped, can only guess how fast vehicle is actually traveling when moving. Taken to dealership, diagnostics run, quoted $390 to replace, including a charge for programming new instrument cluster. Temporarily reset.

2003 Chevrolet Trailblazer ltz; 71, 000 miles. Speedometer stopped and started at 70 mph while I was driving slowly on a residential street. Later that day it dropped to 50 mph as the starting and stopping point even when the ignition was turned off. If an accident had occurred, what speed was being recorded in the vehicle's black box? the Chevrolet dealer says I have to replace the instrument panel. This would cost about $500. Vehicle is out of warranty and I have notified GM.

Trailblazer 4WD 6-cyl

  • Automatic transmission
  • 60,650 miles
I own a 2003 Chevy Trailblazer. It has just over 60,000 miles. The speedometer stopped working correctly a few days ago. The speedometer reads between 85-120 mph no matter how fast I am driving. I have been told by my local Chevy dealer that it will cost around $400 to have the speedometer repaired. I believe Chevrolet should be responsible for the replacement/repair costs since this is a safety issue that numerous other Chevy truck/SUV owners have also experienced. They should have recalled the speedometers on their SUVS/trucks a long time ago.
