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.

Speedometer stopped working. After vehicle was turned off it started working again. Researched internet and I found the this is a known problem with this vehicle. After talking to someone about it and they have a 2003 Tahoe they have the same problem. If chevorlet is aware of this problem something should be done about it. We spend alot of money on vehicles and this should not happen. I don't feel this is a wear and tear issue.

Trailblazer

  • 71,200 miles
The contact owns a 2003 Chevrolet Trailblazer. While driving approximately 10 to 15 mph, the driver traveled over a railroad track and the engine stalled unexpectedly. There were no warning light indicators illuminated on the instrument panel. The contact made several unsuccessful attempts to restart the engine and observed that the "empty fuel" indicator was displayed on the fuel gauge. When the engine restarted, the fuel gauge displayed the accurate reading. The vehicle was able to resume normal operation. The contact has concerns of the significant safety risk. The VIN was rejected from the system. The failure mileage was 71,200. The current mileage was 71,220.

Trailblazer

  • 30,000 miles
The contact owns a 2003 Chevrolet Trailblazer. While driving 25 mph, the contact noticed that the fuel gauge was not registering the correct amount of fuel. Occasionally, the gauge would indicate that no fuel was present in the vehicle at all. The vehicle was not inspected and no repairs were made at that time. One year later, the temperature gauge, actuator on the air conditioning/heating system, and the speedometer failed. The vehicle was taken to the dealer and they confirmed that the actuator failed. The vehicle was repaired at the cost of $720. The manufacturer stated that no compensation would be provided because the failure was not under recall. The failure mileage was 30,000 and current mileage was 44,000. Updated 4/23/09 updated 04/28/09.

Owned 03 Trailblazer for 4 months and has given me electrical & mechanical problems. I had one problem since I first bought this vehicle and now I have 13 things that are a danger to me and my family. Ac turns on by itself whether car is off or on. Ac has turned on while I was driving frightening the hell out of me causing me to almost lose control of the wheel. Ac, engine lacks horse power, hand brake, hazard lights, lights turn off, mirrors move by themselves, car boggs as if it wants to turn off, while driving steering wheel moves by itself, gas gauge has read low fuel when gas is full. I am terrified the car will give out with my child and I in it.I have tried to have vehicle repaired numerous times and still dealer can't seem to duplicate the problem. The vehicle is a hazard to me and my family and to all those who own one. Need the problem to be fixed before any tragedies occur.
