Several times that I've been driving the trailblazer, the speedometer goes crazy and says that we are traveling at a much higher rate of speed than we are. Like if im going approx 70mph, it states we are going about 110mph! this is definitely a safety issue! and it has never been a recall?
I own a 2004 Trailblazer ext and a couple of months ago the RPM gauge stopped functioning and doesn't even register. Less than a month later the speedometer started malfunctioning and many times doesn't even register a speed while driving for several hours. This has been a daily occurrence every time my wife and family get in the vehicle. This is a serious safety hazard for my family and for anyone else we may pass on the road. I know from reading multiple other complaints across the internet that this is not an isolated issue and that GM has already recalled the console cluster on several other models having the same or similar issues. When are they going to be held responsible for also recalling the same problem on this vehicle make?
I started to lose the high speeds on the fan blower. In checking the internet I found this is a common problem for G.M. the problem is the blower motor resistor. When I went to replace this part I found that the whole wiring harness had been burnt to. It got so hot that it melted everything. The fuse for this did not even blow. This could have set the truck on fire. It is funny how the parts to fix this has much thicker wire. The parts in total was around $118. Thanks to a friend I had no labor cost. If I would of taken it to a G.M. dealer for sure they would of wanted over $300. G.M. knows they have a problem and are doing nothing about it. I feel this is a serious matter as it could of set the truck on fire.

I have many electrical issues with my 04 trailblazer from my window lights on the drivers door and the passenger door. I have had my radio replaced because it melted one of my cds. My head lights work when they feel like it same with the rear wiper. It has stalled out in traffic on me. I have also heard that in most 2000 to 2006 trailblazers the reason for the electrical problems is because water is running down the passenger side door into the dash and hitting one of the main wiring harnesses causing it to have many electrical issues. I heard this from someone who has an 06 trailblazer that just had it a replaced for $700 to fix and was told that it will just have to be replaced in a few more years because they cant fix the problem.
Speedometer freezes and you can't tell how fast you are going. Happens quite often. Brought it in, but they were unable to diagnose the problem as it wasn't happening at the time.
We have a 2004 Chevy trailblazer, that originally began with the speedometer appearing to be stuck for a few days, would gradually decrease. Followed by the RPM having the same problem. Today, 11/28/08, all gauges lit up, warning bells rang, and then the entire instrument panel shut down. There was a recall for the Silverado for the same year, but trailblazer owners are required to pay the repair bill for a faulty instrument panel. Being unable to know your speed, how much gas you have, or if your running low on vital fluids seems to be pretty dangerous to me. The fact that GM will repair the Silverado, but not the trailblazer despite the fact that they are both in the "truck" category is ridiculous. It seems to me that any one of these problems can lead to death or injury of the occupants of my vehicle, either by fire, stalling in traffic and being hit by another vehicle at a high rate of speed, or because of the inability to ensure that my vehicle is operating with the proper vital fluids, as well as maintaining a safe rate of speed. My teenage children also drive this car on occasion, and though they've been driving for 3 & 4 years, they do not have enough experience to operate this vehicle safely. There was a recall for the brake lights, how can they justify that when people are driving around without properly working instrument panels? the solution being offered is for the consumer to pay at least $500 to repair something vital to the safe operation of the vehicle, but GM will replace the taillight/brake light that costs pennies on the dollar.
I own a 2004 Chevrolet Trailblazer ext. In Nov 2007, the speedometer and tachometer started acting erratically. The tachometer would seem to stick and the speedometer would register either grossly over or under my current speed. It sticks when trying to accelerate after a deceleration. I have been able to get it to reset only after turning the engine on or off several times consecutively. I have been going down the interstate at speeds of 70+ (within legal speed) and the speedometer will show -5 mph. Also, I have been going approx. 60mph and the speedometer shows 90+mph. I took it to the dealership where I purchased it in Nov 2007 and at the time, their instruments couldn't detect a problem mileage at time of failure approx. 104,000 (had a 100,000 warranty). They charged a $100 diagnostic fee to tell me they didn't see a problem. Current mileage is approx. 134,000. I have not had the problem fixed.
Automatic transmission shifted out of third and would not shift back while I was on the freeway. Dealer said a transmission flush and fluid change would fix it. After performing flush dealer transmission was shot and needed replacement. Instrument cluster functioning intermittently, speedometer works at first and then slowly goes down to zero.
The speedometer on my 2004 trailblazer works intermittently. This began in the fall of 2007. Sometimes it works seemingly fine. It will then freeze on a speed. Sometimes it will register a speed that is obviously incorrect. For example it will register a variable speed that is 20 or more mph faster than we are traveling. It sometimes points straight down. Then last week "out of the blue" it worked again for a few days. Unfortunately, this only lasted a few days. I never know how fast I am going and try to stay in the flow of traffic. I asked the dealer about this and they did not mention any other problems with this and told me it would cost $500 to repair. This is a real safety issue.
2004 Chevy trailblazer. Intermittent engine stalling since new. Many service visits to Chevy dealers to fix, however mechanics stumped. Local gas station mechanic found the problem having to do with components in the emission control / vapor recovery system. Now Chevy needs to figure out the cure. In the meantime I get to drive around with the "check engine" light on. I guess this is better than being crashed because my car stalled in an intersection or on the highway. Chevy mechanics and engineers need to get the "duh" award. Very bad customer service and diagnostics performed by Chevy. I would still like to have the check engine light to go off, and have the engine not stall if that is possible. Please send info to have this done if possible.
I am complaining about a 2004 Chevy trailblazer problem the speedometer is measuring incorrect speed or not working at all. I can be parked and it reads 60 mph I am driving it reads 120 mph. In speaking with several GM owners this is a problem with quite a few GM vehicles and is very dangerous. I think this should be looked into before someone gets hurt. It is very scary not to know what speed you are driving at. In speaking to several owners and looking at web sites of complaints this is a problem and has been one for a long time. I do not blame my dealer I blame Chevrolet or GM whoever made the car there are so many complaints about this speedometer with other makes from GM, its not the dealers fault for this problem.
Engine stalls at various times for no reason. Have had it into dealership many times. Dealership has been unable to isolate problem. Service engine soon light came on after first stall. Dealership reset computer. Since then, the engine has stalled at least 5 times. Ses light has not come back on. Engine usually restarts after approx 5 minutes.
Full destruction because of fire I was on the way back from a long trip in southern chile (up to ushuaia) over the "carretera austral" and, after about 9'000 km drive without any problem, I saw a white smoke back my vehicle. Oil pressure: Normal, motor temperature: Normal. This meant immediate stop along the "ruta 40 norte" in argentina (about 100 km North of bariloche, on the way to neuqu). While stopping, I felt the brake pedal just going without immediate reaction but the pression came back. While bringing the gear shift to position parking, I did not feel any sensation, as if it would have no connection; the automatic door blocker connected to the gear shift did not work too, so that we had to unlock the doors manually. After having disconnected the engine, I saw white smoke coming out from the upper left corner of the motor. I opened the capot and the smoke came from the left corner (close to the driver's place). Suddenly, some material in flames fell to the bottom, about middle light left of the car. I tried to put out the flames with the extinguisher, but other burning material fell. Other people had stopped and helped me. We pushed the car a little ahead - though the hand brake was tied and the gear shift on "P", but burning material fell again. In the meantime, my wife and children throw out the luggage, so that we could save almost all of it. But the car burned entirely. What could be the reason of this incident ? thanks god, I stopped immediately so that nobody was injured nor burned and no third party suffered any damage.
There has not been an accident yet, just one looking for a place to happen. My vehicle I believe has an electrical problem. Which in turn affect all functions of the vehicle, safety being one. I have had (2) fan switches go bad (2) crankshaft sensors go bad. (1) cruise control malfunction. (1) turn signal relay (1) radio console replaced for overheating (1) headlights when below 32 degrees flucuate in brightness till vehicle warms up. Dealer stated this is normal operation. Ha, ha, and transmission shifting problems (1)they reprogramed computer to solve, next some solinoid replaced and now the problem is back. I have a family of 6 that I have in the vehicle 90 % of time. I now have concerns that the wiring must have a short somewhere. Which potentially could cause a fire, or an accident due to what happens when the headlights go out or antilock brake system fails or taillights, etc. GM refuses to replace wiring in vehicle. GM rep told me to contact whoever I wanted to. They are not going to stand behind fixing the problem. Just keep replacing the electrical items as they go bad.
