While driving on the freeway, my speedometer failed and started reporting the speed well above the speed I was going. My speedometer now gets stuck between 70-120mph even when parked. This presents a safety issue as I have no idea of the speed at which I am traveling.

The speedometer does not display correct speed, will show 80 mph when only going 35 to 40 mph. When turning off engine needle will not go back to zero. Very dangerous.

- Seven Hills, OH, USA

Driving down the highway, looked down to check speed and it read zero. The tachometer said zero. I had to pull over and re-start the vehicle. Re-starting it worked that time but not the next day when it happened again. This happens all the time now. I don't know how fast I am going. I was told that it would cost me around $500 to have it repaired.

- Elmira, NY, USA

Speedometer stops working at random times. It will stick at 100 and stay there for a while. Sometimes it will correct after repeated starting of the engine. This is very dangerous and I was told it would cost $600 to repair. I have seen that this is a pretty consistent problem with this model SUV.

2004 Chevy Trailblazer. The speedometer does not work properly.

- Clarksboro, NJ, USA

The instrument cluster went out on my 04 Chevy Trailblazer which I purchased new at around 40K. Chevy will do nothing to help and in the meantime I have no speedometer, tachometer, or gas gauge.

2004 Chevy Trailblazer speedometer reads much faster than I am actually going. When I am at a complete stop, it reads up to 60 mph. This varies by day, some days it is 30, some it is 45, etc... this is extremely dangerous as I never know the actual speed I am going and just have to use my best judgment. Also, check engine light has been on for 2 years and dealer cant find anything wrong with it.

- Gilman, WI, USA

Speedometer started failing after 30-45 min of driving then got more frequent. I took it into local dealership where I purchased vehicle in las vegas and they told me it could be anywhere from $400-$600 to repair it. I have since learned in the last year that this is a huge GM issue and I am glad I did not have it repaired as of yet.
