All electronic gauges within the instrument cluster failed at random times and very frequently, leading to the clusters' current state, which is all gauges are non-operational (dead). Hazardous condition caused due to speedometer failure. Chevy replaced the instrument cluster two times while under 36/36 mfg warranty. Chevy refuses to replace current instrument cluster since 36/36 has passed.

The contact owns a 2003 Chevrolet trailblazer. While driving approximately 65 mph, the contact observed that the speedometer would fluctuate continuously providing inaccurate speeds traveled. In addition, the tac and oil pressure gauges completely failed to operate. The vehicle was taken to an independent mechanic for inspection. The technician was unable to locate the problem and the vehicle was not repaired. The failure mileage was approximately 88,976.

Bad electrical problem. My side mirrors aren't working at all. My rear brake lights are always inoperative. I always get a constant vibration coming from the engine. My gearbox sometimes freezes or gets stuck. Poor fuel efficiency.

2003 Chevrolet trailblazer - instrument cluster malfunction. Speedometer readings are erratic, fuel gauge is stuck above full level, water temperature gauge also has erratic readings. GM recalled the Suburban and Tahoe for this issue but not the trailblazer.

Chronic problem/failure of instrument gages/cluster relating to speedometer, temperature and oil pressure for a 2003 Chevy Trailblazer ext. For example, the speedometer will unexpectedly raise to an alarming speed reading while the vehicle is not actually traveling more than a few miles per hour. Dealer advises that this condition is not covered by any recall notice and GM is unwilling to provide any assistance to alleviate this serious and unsafe condition. Other GM vehicles have been recalled for this exact condition. Also, this vehicle has experienced a cracked exhaut manifold due to poor design/engineering.

Headlamps keep going out and the connectors keep melting and burning the rear radio speakers go out the rear heat/air goes out the level 5 setting on the fan does not work these are not unusual complaints for this vehicle, there seems to be a standard being set with these issues.

I own a Chevy trailblazer 2003, and all the gauges are have quit working, it is unsafe to drive without a speedometer and gas gauge along with all the other gauges. I have replaced fuses and relays nothing has yet to fix the problem.

I own a 2003 Chevy trailblazer ls. Bought it new off the dealer's lot. In 2007, approximately 100,000 miles later the tachometer began to function intermittently. At 120,000 miles, it quit all together. Shortly thereafter, the speedometer began to malfunction intermittently. Now in 2009 and 150,000 miles it does not work 90+% of the time. When it does, the speed indication is unreliable. I have taken the vehicle into the local Chevy dealer for diagnostic and repair estimate; $800 to $1000 all day situation. Have taken it to other repair shops, but they refer back to the dealer in order to obtain parts. So far, have been able to operate vehicle, but awaiting the next gauge to fail.

My RPM gauge and fuel gauges both stopped working.

Beginning 2 weeks ago the speedometer on my 2003 Chevy trailblazer has not been working properly. The needle will go past 120 mph and when your stopped it will be at 30-40 mph. This is extremely dangerous since my son has his learners permit and was driving the first time the speedometer malfunctioned. We were on the highway. I looked on-line and found several people with the same problem. One suggested disconnecting the battery for 5 minutes. I did this and it worked for 1 week. I disconnected it 2 more times so far. Today I called GM at 800-630-2438 to report the problem & see if there was a recall. I was told there was no recall but that I should take it to the dealer for diagnostic testing. I asked if I would be charged and she said yes. I told her that I can't afford to pay them just for diagnostics and that they already know what the problem is since it is all over the internet about so many of their vehicles doing this.

I purchased the vehicle with approximately 63,000 miles already on it. Within a month I noticed the speedometer was doing funny things like reading 100mph when I was only driving about 25mph. I contacted a dealer and was told it would cost $500 to repair. We do not have that kind of money so I left it. The problem continued until the speedometer stopped working altogether. I had learned how to gauge my speed by using the takometer but that started to go shortly after the speedometer. Now my battery gauge is starting to show signs of fritzing. I have read online that this is a very common problem with these vehicles and that GM has not issued a recall. I now have a gps which can tell me my speed but the battery gauge is a definate safety issue. Thank you!

My check engine light came on but the vehicle ran O.K. took it to mechanic and was told that the oil pressure gauge was not working and he believed there was a recall on this. It wasn't a recall so we were told we would have to pay for the repairs ourselves and since we regularly change/check our oil I wasn't too worried. Now we have noticed the temperature gauge has shot all the way around and has stayed but when it is really cold outside it drops back to normal. The speedometer and the RPM gauge also sticks. Spent many days for a few years trying to solve problem with the radio and dvd player not working properly and switching stations on its own and after several replacements finally gave up because it was never corrected. This is a real concern as I do travel by myself and rely on the instrument panel and this seems to be a real problem with the trailblazer and should be recalled by chevorlet.

My 2003 Chevrolet Trailblazer ext gauge clusters malfunction. One by one the instrument panel gauges have been failing. First the RPM gauge stuck at zero in March '08. About two months ago (Oct '08), the oil pressure gauge dropped to zero and now fluctuates erratically. Often times, restarting the car will temporarily reset the oil pressure gauge until it fails again. This month (Dec. '08), the temperature gauge pegged high and the speedometer will temporarily hesitate. The only gauge that appears to work properly is the fuel gauge, and I'm guessing that will eventually fail too. During my last oil change at a Chevy dealer, they indicated that most likely the instrument cluster/gauge drivers are bad and can be replaced for about $800. I've done a lot of searching on the internet and found that many people are experiencing this same problem with Chevy vehicles, yet Chevrolet has done nothing to correct or remedy the situation.

While driving, the speedometer got stuck at 40mph. It never came back down, but eventually went all the way to the right side. After $900 for a new instrument cluster it was fixed, but the following year a friend of mine with an 05 trailblazer had the same thing happen to her. She won't get it fixed because it seems just a tad bit suspicious that so many speedometers have gone out in these things.
