I have 2004 Trailblazer in Jan my tach and speedometer have not worked properly...I cannot afford the 500 dollar plus fix on this vehicle. I have read many complaints in regards to the same situation. Apparently no one has taken care of this problem. Ifrom my understanding there have been recalls on most other vehicles with the same problem, I do not understand why there isn't one for the Trailblazer.please advise what to do.

I can start my vehicle and the gauges started sticking. I am constantly being shocked by the driver door. My gauges no longer work at all and have completely went haywire. I have no dash lights. My vehicle has just died in the middle of a busy street. I do not know how much fuel I have, how fast I am going. My cruise control either at times increases my speed or does not hold the speed. I have to use a gps device to know approximate speed. This vehicle needs to be recalled. I love my vehicle but it has tons of issues.

Instrument cluster started going bad in 2006 and every year another gauge is faulty - first it was the gas gauge, next the oil, etc and 4 years ago the speedometer started sticking. I talked to the dealer and they wanted $800 to fix it. I have researched at the time and this it is a very common complaint. This should have been recalled. I have complained about it for years and even called GM - no help and I don't have the money to repair this. I would appreciate help with this and feel that GM has known that this is an issue. I drive a lot of kids in my car and I am afraid that one day this is really going to be a problem.

While driving the vehicle it began to smoke. The car wouldn't accelerate so I stopped the car shut it off, popped the hood, and it was engulfed in flames. I grabbed my 2 children out of the car and called 9-1-1 the car was a total loss!

Speedometer gets stuck at random places. Impossible to know how fast you are going. All other controls have also gone out too. The oil pressure gauge was the first to stop working and the rest have gone out about a month or 2 apart.

Vehicle goes into shutdown mode with an unresponsive accelerator. Motor still runs but no acceleration. This is a serious safety issue when driving in traffic as you have no power to get out of traffic and harms way. There is no warning that a problem is imminent. A reduced power light comes on and you're stuck. Vehicle in question is a 2004 Chevrolet Trailblazer.

The speedometer began to be erratic and would not show the correct speed. I could be traveling 40 mph and the speedometer would show 10 mph. Then it would jump to 110 mph, then zero. I went to the dealer and was told a new cluster board was needed. The replacement cost is $600-$700. I did an internet search and found out that his is a wide spread problem with the Trailblazer. I also found out that chev. Has recalled other vehicles with the same problem, such as Suburban, Silverado and Yukon, but has not recalled the Trailblazer. This is a serious safety issue. Chevy must be aware that this is a big problem for Trailblazer owners there needs to be a recall of the cluster board on the Trailblazer.

I have safety concerns in regards of my vehicle. While driving, my speedometer is reading off wrong numbers. For example, I can be driving 60mph, but the speedometer is reading at 80mph. It is a real concern for me because I have know idea how fast I'm driving. Now that a lot of cities have photo-enforced cameras to record how fast you are driving, I have to guess how fast I'm going and hope that I don't receive a ticket in the mail. I have been researching this particular problem and I see several complaints on this topic. Unfortunately, my warranty is expired so I will have to pay out of pocket. I hope GM sees this and consider a recall

The contact owns a 2004 Chevrolet Trailblazer. The throttle body failed while the contact was at a stop light causing the vehicle to stall. The vehicle restarted immediately and there were no warning lights illuminated. The vehicle was driven to a mechanic where they inspected and replaced the throttle body at her expense for $200. The dealer was also called and informed her to bring the vehicle in for diagnostic testing but she informed them that she would take the vehicle to another mechanic and they will replace the throttle body. The manufacturer was called, filed a claim and was also informed to contact NHTSA and file a claim. The failure mileage was 121,000. Updated 12/8/10.

I have never been in an accident or anything like that. I loved my vehicle and took very good care of it....

  • 74,100 miles
I was driving at highway speed (approximately 65mph) with the cruise control set, when my vehicle suddenly responded like I had slammed the gas pedal down to the floor. My speed climbed rapidly, but I had the presence of mind to drop the truck into neutral (the tachometer continued to be at its maximum level and the engine still whined high) and steer to safety, across several lanes of traffic, to the breakdown lane. When I shut the vehicle off and turned it back on again, this issue was no longer present.

Driving on dry pavement, clear day. Took freeway offramp, when I reached 40mph, the brakes locked up, went past stop sign into other highway missing other vehicle passing in front of offramp. Happened twice at same speed, brakes lock up, and I pass through the stop sign. Loud grinding noise coming from wheel well area, brakes recently changed about 3 months ago, noise occurs at 25-30 mph, sounds like dragging something underneath. Service man checked, nothing visible. Has occurred 5 times in less than 2 months. Interior lights dim on vehicle then brighten constantly. Door ajar light constantly coming on, back hatch window constantly opening on own driving down road. Instrument panel knobs, panel itself and window and door buttons on doors extremely hot to touch. Various lights on instrument panel quit working and then resume on their own. Reported tach/odometer not working already. Both units registering offline while driving. Where are the fixes to these problems?
