The speedometer on my 2005 Chevy Trailblazer is out of wack. It registers at least 3 to 4 times faster than I am going. I have no way of knowing how fast I'm going.

- Otisville, MI, USA

Speedometer stopped working while driving on the freeway. The only reason I found out was chp stopped me for going 45 mph. Once I began to slowdown the speedometer jumped to over 100mph! I explained the situation and he followed me to the next exit where I let the car rest. He knew I need to let the car rest because he had pulled over another Trailblazer with the same problem!!

I own a 2005 Chevrolet Trailblazer, have own it since I bought it in 2005 and have no problems up until recently. Today I was driving down the highway when my speedometer quit working. I would not show the correct speed in which I was traveling on the highway for the posted speed limit, realizing that everyone else on the road seem like they were parked on the highway, as I am flying by them is when I realized that my speedometer/instrument panel. This problem happened on my travel to a location and back on a couple of occasions. I managed to figure out that the longer I had the vehicle running the problem would occur. If I shut the vehicle off and let it cool down it would be fine for about 15-20 mins than act up again. This is something that is unsafe and can potentially cause harm in the near future if it is not addressed with other owners. Luckily I did not cause any accidents or pulled over.

We bought a 2005 Trailblazer about a year and a half ago. Out of the blue about two weeks ago, the speedometer goes haywire. It says that I am going 60 mph. When I was actually going about 15 because I was in a residential area and it was snowing. A few days later it started working again, and then today it just completely stopped working. It wont move at all. Its completely broken.

- Hinesville, GA, USA

The speedometer in my 2005 Chevy Trailblazer has broken and I only have 45,000 miles on my vehicle. I heard about a recall or getting assistance from GM to replace but learned it is only for Tahoe's, Suburban's and trucks. I don't feel that is fair they won't help me and that a speedometer should not wear out that quickly. Replacement cost can be $600 - $800.
