Speedometer first showed speed of 60 when sitting still. I turned off the engine, restarting it 3 times and the speedometer reset. But a few days later it once again stuck and I had just started it. This time at 48 at all times whether the engine is on or off, idling of traveling. It continues to be stuck at 48 at all times, never decreasing or increasing.

I can't tell if my tank is full or empty

As of 2011 (while driving on freeways in multiple occasions) I've been having electrical issues such as my fuel level gage would read full and vehicle would shut off cause no gas in tank, air bags sensor would show it on when no one is sitting in the passenger seat, and there are some electrical issues on driver seat controls not working, dash board gages not showing readings while vehicle is in motion (rmp, speedometer, oil, gas).

The speedometer doesnt work.

- Hyattsville, MD, USA

The speedometer has become unreliable; it sticks / jerks while driving after which it does not display an accurate speed. I've had my speedometer read 30mph while completely stopped. It has a greater tendency to stick around 50-60mph. Repeatedly starting the engine, causing the speedometer to go through its reset cycle will move the needle back to 0mph in approximately 5mph increments for every start. This only provides a bit of reliability for short trips.

Car will not accelerate. Revs up really high without acceleration.

First my rear wiper and rear washer stopped working but when you turn the button it sounds like it wants to go. Second my speedometer is all over the board. Sometimes it runs low, sometimes it's higher and at times it just won't move. It has also been off the board pointer down at the prnd321. Third my oil gauge stopped working.

The speedometer gets stuck on a speed and the only way to get it back down to 0 is by turning the engine on and off several times. This has happened to me several times in the last few months. From my research on this it appears this is happening to many many people but nothing gets done about it. It seems to me like it should be a recall to get it fixed.

The airbags will show that they're not enabled even with a passenger sitting in the seat.then it would come on as being on but no passenger in seat. A lot of sensors have popped up in the electrical panel, on top of that the car kinda shut down on me and started going 10 miles per hour, as I was going out in traffic.

Dash controls and readings all go out. Speedometer does not show speed. Oil pressure gauge does not read correctly.

- Streator, IL, USA

The engine light constantly comes on even after I had a tune up. I had diagnostics done and there is some type of fuel misfire. Two winters straight I have had issues with the power steering lines bursting and replaced 3 times. The speedometer malfunctions, most of the time it just stays at zero. If GM uses a lot of the same parts to make multiple models why has the 2005 Trailblazer not been recalled? I was told the GM Envoy has the same engine and other inner workings as my Trailblazer so why wouldn't their recalls apply to my vehicle especially if I may be having the same issues.

The speedometer in my car started not working a week ago.. it would say I was going 70 and in reality I was only going 55. Now it starts out at 110mph when I start driving....making it really difficult to know how fast/slow I am going. I have read many articles of this happening with this make and model of vehicle.

Speedometer stopped working a few times until it completely has gone dead and doesn't work at all. My Trailblazer also has stalled if stopped at a red light more than once.

When the steering is turned too far the car automatically and very suddenly shuts off, no matter where we are. Seatbelts in the last row of the vehicle don't lock so, our car seats just slide due to never ending seat belt. Engine and oil light come on when car is started and will stay on for days as result of gas cap being not screwed on properly. Delayed turning reaction with steering wheel, horn got stuck and would not stop sounding so it had to be disabled.

I purchased my SUV in August of 2008 about a month later after pumping gas I noticed the fuel gauge spinning uncontrollably. Due to the warranty I purchase carmax fixed the problem at that time not it is 5 years later and exact same things has happened as well as all the other gauges spinning. Shortly, after the fuel gauge went out I notice the speedometer and the accelerator gauges doing the same thing. I have had my SUV for 5 years and has constantly complained about the gauges spinning back and forth.

The contact owns a 2005 Chevrolet Trailblazer. The contact stated that while driving at 35 mph, the accelerator pedal was released but the speed failed to decrease. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The VIN was unavailable. The approximate failure mileage was 127,000. Djr

My trail Blazer check engine light stays on we cannot reset it. The full gauge says it has more gas then what it does, I have to guess to avoid running our of gas. Speedometer stops working then it fixes its self. The radio and lights sometimes stay on, and kills my battery.
