My 2005 trailblazers headlights flash when you let up off the gas pedal. Also, the amp gauge drops, the engine revs down and the inside fans and lights dim down. The flashing of the headlights is getting worse, and like others have reported, the traffic ahead thinks you are blinking them to either pull over, or speed up. I too notice it more in the colder months. I agree -this is definitely a safety hazard! Something needs to be done about it. I have reported the problem, but they say nothing can be done. Purchased this SUV brand new, had problem from the beginning. Too many people with same problem. General motors should be ashamed.

I have a 2005 chevrolet trailblazer ls v6, and I was going down the interstate when I notice my speedometer read 30 MPH. I knew I was going faster than this so I pulled over to the side of the road and cut the engine off and restarted it. It began to work fine until the following monday evening when it did it again, this time only registering 0 MPH when I was driving approximately 30 MPH. Finally on 01/13/08, I got in it to go to work and it was registering 120 MPH but the vehicle was at a standstill.

I have a 2005 trailblazer and the speedometer is not working correctly sometimes is stays on zero and then there are times it reads 120miles when im guessing I'm going around 30 miles and there are times when in park it reads any where from 40 to 60 MPH. Has of now I do not have the means to fix the problem and not that I feel I should have to pay out of pocket seeing how I believe this is a gm problem and not mine are the other hundreds of gm owners with the same problem! This is a safety issue that should be resolved as soon as possible....oh and it is a everytime I drive this gm product occurrence,,,I never know what speed I am truly going!!!

2005 chevy trail blazer. I've heard several complaints on this speedometer subject, and from what I understand it can be a very expensive procedure, hopefully my complaint can push for a recall.

I was driving down the road driving about 40 MPH, when I noticed that my speedometer was reading 80 MPH and above. By the time I got home it was on 120 MPH and now it wont go back down, it just stays on 80 MPH until I drive it, then it jumps back up again.

Speedometer would be reading a speed when I was sitting still and would just keep increasing until now it sits way past 120mph and move at all.

Speedometer is broke mostly on 0 miles per hour while driving. I may be over speed limit without knowing.

My headlights and dash lights flicker while driving. Also while driving my lights will dim and the blower for heat & A/C will slow and then pick up to normal speed again. It also revs by itself, even in park and will go forward slightly when it does surge. These problems only started after the alternator was replaced. I think it is a safety hazard to have lights flickering and engine surges.

Sudden speedometer failure.

Speedometer shows wrong speed while driving. It corrects itself after 2-3 days. Usually occurs while driving on the highway.

My speedometer is not reading to correct speed on the chevy trailblazer from 2005. It is up and down and when parked could be at zero or 15 MPH...it is always changing. This could be very dangerous if you are on the highway or trying watch your speed in a neighborhood. I have seen lots of complaints about this problem. It should be fixed by gm since it is a common problem. I am taking this back to the dealer to see what they can do, but I probably cannot afford to fix it any time soon.

Headlights, dashlight dim, battery gauge jump. The headlights, dashlights and all power dims or cuts out when letting off the gas. When in the gas it works fin. When I let off everything starts dimming and cutting out. At night time people in front of me think I'm wanting them to pull over because the light flash like a police cars would. I see many of the same complaints in msg boards and the dealerships know of the problem but have no fix. They tell you to deal with it. I think its a real safety issue and need to be addresses.

I recently bought a 2005 chevrolet trailblazer and suddenly the speedometer began sticking, and not working, then working again. Unfortunately when it does work, it does not tell you the correct speed that you are traveling at. This is a safety issue that needs to be addressed to general motors. It continuously works then stop, and displays inaccurate speeds. Looking at the complaints on this website there are numerous people having the same problem.

The headlights, dash lights and dome lights all flicker intermittently. I have had this problem since nov 2004 when I bought the truck. Recently I've noticed the battery gauge fluctuate rather wildly when this problem is occurring. In my case, there seems to be a connection to the outside temperature. However, given the intermittent nature of the problem I can't be certain. I have noticed the problem more when the temps are around 35-45f. The dealer has seen the vehicle several times for the problem and still can't determine the issue. The big problem is they haven't been able to reproduce the condition. The truck now has 75000 miles and is 4 years old. The flickering/flashing has gotten much worse. On dec 2, 2008 the flickering was more akin to outright flashing. Other drivers being noticeably affected.

While driving at approximately 30 MPH, my speedometer suddenly went to 90 MPH. I stopped and turned the ignition off. Afterwards, the speedometer has steadily increased to the point where it begins at 100 MPH. I have no idea how fast I am really going! I have not replaced any parts as this happened last night. Moreover, I understand the cost of repair to be rather excessive at ~$500.

Instrument cluster malfunctioning. Speedometer, tachometer and oil pressure gauges are inaccurate. Also had to replace fuel sensor/sending unit before vehicle reached 50,000 miles.

Instrument cluster. My speedometer has failed. My fuel gauge had failed a few months ago. My doors lock by themselves even when you are out of the vehicle. A couple of times away on a trip and locked out of the vehicle. My lights flicker at night to almost off. Chevrolet said they don't see a problem however if you get on line you are able to check many complaints about the trailblazer of the same situation. Why does the consumer have to pay out of pocket for a product with many failures that should not have happened.

The speedometer on my 2005 chevrolet trailblazer went haywire last weekend. On tuesday with my wife driving our 3 month old infant to daycare, and herself to school, the gauge on the speedometer quit completely and currently is pointing straight down and will not move regardless of the speed that I am traveling.

The vehicle in question is a 2005 chevrolet trailblazer with under 40,000 miles and very well-maintained. This is a continuing concern and have had the dealer mechanics look at this problem. While driving at any speed, the lights will dim dramatically when the accelerator pedal is released. The headlights and interior lights dim and return after accelerating for any length or magnitude and then return to normal brightness. Typically, they will dim 3 times. I am concerned about how severe this could become. The dealership said gm acknowledges this happening but says it is normal and no repair is available. This does not happen all the time but does happen 2-3 times a week and inconsistently. I cannot identify what causes it or what conditions consistently exist. However, this cannot be normal or safe.

The speedometer does not register the correct speed all the time. I was driving down the highway at 70 MPH and the car said I was doing 110mph. The dealer said file a complaint because they get this problem a lot. There have been recalls on other gm cars with the same gauges as the 2005 trailblazer. So why has there not been a recall for the trailblazer?

Speedometer worked fine then started going in and out, now completely stopped working, spoke with several other trailblazer owners same problem, spoke with a worker at gm stated several vehicles have been repaired for problem.

When driving at night typically while "coasting" between 30-50 MPH my headlights on my trailblazer dim, the battery charge goes down, and the blower stops working for just a second. After researching this on the internet I have noticed that many other people are having a similar, and unresolved problem with their trailblazers as well. This is dangerous because headlights are necessary, also something that should not be a consistency with many consumers. Mine is a 2005 chevrolet trailblazer ls. I hope is matter is looked into more since there is a huge problem that many customers are having that is getting ignored. We need someone to look out for us!

My vehicle headlights in my 2005 chevrolet trailblazer, blink, flicker or flash when too much power is going in, I don't think this vehicle has a big enough alternator, but the dealer or gm will not do anything to help me, they said its normal. If its normal that the headlights flicker, I would have never bought this vehicle. It is just so frustrating to have a vehicle in a shop when you need it for day to day living. This has been going on for 8 months now. This could kill someone and according to multiple blog sites this is a problem for a lot of people.

2005 chevy trailblazer v6 ls speedometer has failed. This is extremely dangerous. Chevy has refused to issue a recall although there are hundreds, if not thousands of complaints. My speedometer often reads 0-40 MPH on the highway. I have a 3 and 1 year old who are with me every day in this vehicle. The fuel gauge has also failed. I have to rely on my tripometer to know when to refuel. I cannot afford to run out of gas with 2 young children, especially with the new england winter around the corner. Please, please, please investigate this issue and require chevy to take immediate action. With the ecomony so bad, struggling to make ends meet, and the $400+ monthly payment for this vehicle there's no way I could afford to have a dealership fix these issues. Thank you!!!

I have an 2005 chevy trailblazer that the lights constantly are flashing. They dim and then come very bright again non-stop. This can not be safe because for several instances they are so dim that you can't see in the dark. I have had the vehicle in several times when it was under warranty and gm said it was normal when the fan kicks on. Well it is not normal or is it safe. I can not manually flick the lights as fast as they flicker when I am driving down the road. It is very unsafe and gm needs to find a fix for it.

Headlights and dashlights flicker erratically that it almost looks like you are flashing your lights at oncoming motorists. Have had it to the dealer more that six times for this without resolve. The dealer says it is normal, and they don't care if we get killed.

I have a 2005 chevy trailblazer lt, and I have noticed this strange sound lately when I start it up and it gets louder as you drive it. My father said that it is the bearings and the alternator, so I decided to look it up on the internet and saw multiple complaints on this issue with this particular model. I was told to file a complaint on a site, and was directed by many others who have experienced this issue. I am not happy, and I still owe on this vehicle and the warranty is conveniently up just as this is happening. I want this correct, and someone contacted gm and they stated that there is an issue with the pump and the electrical, well then they need to recall this vehicle and fix it for free.
