My third complaint about my 2005 Trailblazer. I really do hate this car. So, I'm driving down the highway and start to freak out when I notice my speedometer. It read 110mph!!! How could I be going that fast! Other cars were flying by me. I'm sitting at a stop light and my speedometer reads 35mph. What the hell is going on here!!! It has been just a few weeks since this started. I'm sure it will cost a lot of money to fix. I again, refuse to pay any money to fix a problem that should be fixed by Chevy. I will report my complaint like the others and get rid of this hunk of crap ASAP!!!

My speedometer has multiple personalities. It works when it wants to, but more often than not it doesn't. Sometimes it says I'm going 0-40 on the highway. This is SO dangerous and once again, Chevy won't do anything about it!!! I really like the vehicle, but hate the problems with the gauges. My check engine light has been on for a year, the fuel gauge has failed and the speedometer. (I've submitted those complaints as well)

I think I may just buy a new (used) gauge cluster. Do I need one with similar mileage or will my car retain it's current mileage with a different cluster??

I have been having this problem with my speedometer for over a year, but just recently tried to get it fixed. GM has not issued a recall on this particular vehicle, even though there are recalls for the EXACT SAME PROBLEM on several other GM vehicles. It can be fixed if you are good with a soldering iron. You have to replace the Stepper Motors on all of the gauges in the instrument cluster. There is a guy on Ebay selling the motors for around $10 with $3 shipping. Just search for Stepper Motor. If you can not do the work yourself, the dealerships are charging anywhere from $400-$600!! The only way we can get a recall issued on the Trailblazer is if enough people file a complaint with the National Highway Traffic Safety Administration, or NHTSA. Their website is

PLEASE, go there and file a complaint.

Update from Jun 26, 2009: I wanted to update my original post. I spent a week talking to several differnt people at GM trying to get them to pay for this to be fixed, but they told me that it was not a "safety issue" and therefore, they could not issue a recall. I have found a solution to the problem though. I use a GPS unit with a speedometer on the screen. This cost me way less than taking my car to a mechanic, and I am not good enough with a soldering iron to fix it myself. Unfortunately, another motor has gone out, and now my gas gauge does not work. I have to keep a close eye on the odometer to see how much farther I can go without gas. This is a huge problem, but I doubt that GM will do anything about it now due to all of the financial problems they are having.

Two days ago my speedometer also went berserk after taking it off cruise control. I called Chevy customer service at 1-800-222-1020 and spoke with a representative who stated "no recall" yet. He further stated the problem had not been common. However, my husband called the local dealer who stated they had fixed MANY, MANY 2003 and 2004 models. It is a matter of time before recalls on the 2005 start if consumers will do their part and call it in. There is no way I am going to pay out of pocket at this point. It is too expensive.
