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.

Trailblazer 4WD 6-cyl

  • Automatic transmission

Speedometer on 2004 Chevy Trailblazer quit working. There are numerous instances of this happening on other Chevy vehicles of the same model year. GM needs to resolve this issue. It is a serious safety issue.

Trailblazer 6-cyl

  • Automatic transmission
  • 47,000 miles
My 2004 Trailblazer's speedometer and tachometer malfunctioned. Everyone I spoke to, including GM customer service and the repairman, seemed to know immediately it was a defective cluster. This is covered on other GM vehicles but not the Trailblazer. There are many cases online where it is obvious it is a manufacturer defect/known problem. My daughter received a speeding ticket for going 49 in a 40 when the speedometer showed she was within the mph limit. It was shortly after that we realized the problem. My situation occurred about a month or two ago. Yesterday I was driving with a friend who had the same vehicle and he mentioned his speedometer was acting up. I told him exactly what happened to me and he is looking into the repair. I feel this is a potential safety hazard and inconvenience and since so many are experiencing the same problem GM should cover the cost of the repair.

Trailblazer 6-cyl

  • Automatic transmission
  • 65,000 miles
I was driving down the road when my speedometer continued to rise even when I stopped. I have a 2004 Chevrolet Trailblazer. There are hundreds of people in various forums with the same problem and Chevrolet has yet to recall or fix the problem. They know that the problem is with the instrument cluster failing but still will not pay to have it fixed in the Trailblazer. The other trucks and SUV's have been found with the same problem and Chevrolet is paying for them but not the Trailblazer. I will need to pay $450 for a new instrument panel to fix the problem. I currently do not have a working speedometer.

2004 Chevrolet Trailblazer instrument panel cluster failure. When taken to the Chevrolet dealer to determine cause of the problem with the speedometer and the instrument cluster they are aware that this is a very common problem with Trailblazers. No recall yet for Trailblazers but there is recall for same problem with many other Chevrolet models including Silverado, Suburban and others. Speedometer failed to work.

  • Automatic transmission

The contact owns a 2004 Chevrolet Trailblazer. While driving 45 mph, the speedometer failed. The contact owned a previous 2003 Trailblazer that had the same failure. The dealer stated that the electronic unit was faulty and they replaced the entire dashboard at the cost of $1,500 on the 2003 Trailblazer. However, the failure recurred. These units can only be purchased from a Chevrolet dealer. The VIN was unknown. The current and failure mileages were 75,000.

GM issued a bulletin for 2003-2004 model year Cadillac escalade, escalade esv, and escalade ext; Chevrolet Avalanche, Silverado, Suburban, and Tahoe; and GMC Sierra, Yukon, and Yukon XL vehicles have reported that the instrument panel (ip) cluster gauges stick, flutter, or become inoperative.

Trailblazer 4WD 6-cyl

  • Automatic transmission
  • 45,000 miles
In December of 2007 the speedometer in '04 Trailblazer with 45,000 miles stopped working. It works on occasion, but is normally stuck. I found this is due to faulty gage clusters and is common on Trailblazers. A recall was recently made on full size Chevy models with the same issue, so I ask that the recall include the Trailblazer model. The speedometer is a vital instrument and is needed for safe driving. I spent $75 for an analysis and was stated the whole gage cluster will need to be replaced for $600 as the stepper motors in these models are faulty.

  • Automatic transmission

When exterior temps are approximately 25 or below, speedometer is completely inop or reads extremely low (20-30mph?) and when at a stop the speedometer will drop well below "0"mph. Instead of a smooth, fluid movement, needle is very jerky and lags. As the truck warms up the symptoms will gradually disappear. In warmer outside temps, the speedometer appears to work normally.

The speedometer cable started acting erratic and no fail to accurately tell me how fast that I am going. From what I understand gmac has a recall on the same cluster that is used on similar vehicles.
