While driving above 30mph, if take foot off accelerator, headlights will dim to almost no light as will the dash lights, on off, on off, when press on the accelerator, lights will go on normally with same brightness. Dome light button to left of steering wheel will work once every 50 tries, lights on left side of radio do not work, cd player will not take cds. I am unable to drive my vehicle at night, it has been to a certified chevrolet dealership twice now, they have stated that everything is running correctly and that they cannot find anything wrong with the vehicle. The speedometer will read 0 (no matter how fast I'm going) which is apparently a known problem with chevy vehicles, but they are not willing to fix it in the trailblazer.
2005 Chevrolet Trailblazer electrical complaints
Page 20 of 22: complaints 551 to 580 of 617, newest first, as owners wrote them.
Speedometer randomly quits working. Started at 70,000 miles.
Speedometer quit working , indicator needle goes up and down, even when car is parked.
I have a 2005 chevy trailblazer, on 1-20-08 the speedometer failed, it stuck on 80 + MPH ( when it should be at zero ) and would only go higher in motion. On 1-23-08 my wife took vehicle to phillips chevy in frankfort, ill. We are told that in instrument cluster is the problem and needs to be replaced, we are not covered under new car warranty because we have exceeded the mileage. I checked with chevy to see if there was a recall in force and there is not. It seems that there are numerous other gm and chevy owners for various years that have same problem and there is a law suit in washington and oregon that are seeking class-action status. I feel that this has been an ongoing problem with gm and chevy and that they should issue a recall to repair or replace as needed.
I purchased a 2005 chevy trailblazer on 4/15/05 shortly there after I was having problems with a whining sound. I took it to a dealer and I was told that it was the ignition pulley. I contacted the corporate office of chevrolet to inquire about assistance with payment considering I was about 3, 000 miles over the warranty. After several calls chevrolet absorbed this cost. Then in sept. Of 2005, my husband totaled his car and I purchased a 2005 trailblazer for him. Again this car began making similar noises and my husband was driving home with our 2 year old son and the car began smoking. My husband immediately pulled off the road and contact roadservice. Once we took it to a mechanic he said that it was the ignition pulley which caused the transmission to die. We took it to a chevrolet dealership and they said that was the transmission. I contacted the corporate office once again and this time they would not offer any financial assistance. It seems that the dealership said that it was the result of an oil change that did not occur at the 3000. They, the dealership based this off of a sticker that was in the window of the car. When I went to look at the car they was no oil sticker in the window. Despite that, I had contacted the chevy office about the same whining noise that I heard in my car (the ignition pulley) that my husband was experiencing in his car. This is still not resolved. We were told to fix this car it would cost $10,000.00, yes, for a new transmission. We have since towed to home in order to avoid storage fees. Here sits a 2005 chevy trailblazer with approx. 50,000.00 and a new transmission is needed. We do not have the money to fix this and also pay the car note on it as well. As a read reports, this is a similar problem with many many trailblazers. There needs to be a recall on this vehicle for faulty transmissions!!!!!
Alternator failed.
Since the purchase of my 2005 chevrolet trailblazer I have had problems with my lights(interior and exterior) flickering (I have noticed this problem at night). My dealership has tried many things on their own and suggestions from chevrolet. The alternator was changed, lights switches replaced, computer reprogrammed. This problem is not being resolved by chevrolet. This problem has some potential to cause serious problems if the events occur during night time driving.
Tl*the contact owns a 2005 chevrolet trail blazer. While driving 55 MPH, the speedometer gauge fell to zero MPH without warning. The dealer stated there is a recall. However, his VIN was not included. The current mileage is 64,610 and failure mileage was 64,510. Updated 01-29-08. *kb updated
Voltage drops occasionally while vehicle is running. This causes my light to dim and engine light to come on. When this happens my vehicle runs funny. I haven't replaced anything yet. I'm still trying to get to a mechanic.
When driving at night only, the headlights and dashboard lights flicker and dim along with the voltage gauge dropping down. After 10 or so seconds, the voltage gauge resets to 14 and the lights brighten to normal. The flickering occurs at steady driving speeds as well as during slow-down.
Speedometer gives an inaccurate reading or sometimes stops working altogether. This problem began 2-3 weeks ago and from other trailblazer owners that I have discussed this with online it is a very common problem. I didn't realize that the speedometer was functioning improperly until it became very obvious - it was registering 30 MPH when I was traveling with the flow of traffic on an interstate freeway. When the vehicle has been turned off and sits for a while, the speedometer seems to reset itself and works properly again for a while, then the problem begins again. From what my research indicates, it is a bad stepper motor that causes the problem, which requires specialized tools and expertise to replace. The cost is in the hundreds of dollars. Given that this is such a common problem and compromises the safety of the vehicle, I strongly feel that this issue should be addressed by the federal safety agency. Thank you.
My alternator went bad, having problems with my lights getting brighter for a second during acceleration and then it goes back to normal. Winding noise coming from my alternator started at 36,175 miles right after the warranty ends.
I own a 2005 chevy trailblazer and I have encountered numerous problems since purchasing this vehicle brand new from the dealer. I have had to have sensors replaced, fuel tank has had to be worked on, and now the main most costly is I am having to replace the transmission. This vehicle has approx. 84,000k miles on it and is only two years old. Please help to see if this should have been a factory recall. I have always had my vehicle serviced at the dealer where I purchased it at.
Alternator bearing started going out at 37,000 miles.
Speedometer in my 2005 chevy trailblazer ext malfunctioned. It read 80 MPH at a dead spot. It would vary its readings, but it was not accurate.
Tl*the contact owns a 2005 chevrolet trailblazer. The contact stated that the seat controls failed and no longer moved the seats properly. The fuses were replaced, but the contact stated that they smelled as if they had burned not long afterwards. She had the fuses tested and was informed that there was a shortage in the fuse box that could result in a fire. The chevrolet dealer stated that they would not repair the vehicle for free because the vehicle was not under warranty. The contact also stated that when she applied the brakes, she heard a clicking noise coming from the fuse box. The VIN, engine size, number of cylinders, and purchase date were unknown. The current and failure mileages were 71,239.
Purchased 2005 trailblazer 3/8/05 @ bacon chevrolet in palestine,tx. Problems: while driving headlight & interior dashboard lights flicker & shut off, engine loses power & surges lunging forward, battery gauge drops & pegs out, check engine light comes on, ding alarm, radio, electric locks, etc, w/ no key in ignition go off & on, no power cant start vehicle. Svc mgr/tech comments: cant duplicate complaint, no codes showing, gm bulletin stating "normal" & working as designed, can not replace or work on anymore due to tech/gm motors stating "normal", or until problem can be duplicated or until they have a way to fix. Repairs:(total of 9 times in shop) 2 headlamp switches, 1 battery, 3 times wiring harness gone through, numerous PCM updates/reprograms, fuel pressure check, ipc reprogram, data recorder installed, replaced bcm body control module, workorders have been altered & work stated done that has not been done. I have all my workorders. Conclusion: took to bbb of tyler,tx.cs#chv0592738, had arbitration hearing. Bbb's decision was that their opinion was that the lights going off while driving was not a safety issue. Thought the bbb was suppose to be a consumer advocate! I found this website while doing a college research paper. How many other consumers have same problem, but do not know about this website. Will anything be done before someone is killed or is that what it will take!
Tl*the contact owns a 2005 chevrolet trailblazer. While the vehicle is being driven or idling, the electrical system shuts down. The failure occurred at night when shutting off the headlights and the instrument panel; however, the engine does not shut off, only the electrical system. The failure has occurred on six occasions. Speed was not a factor. The dealer replaced one of the circuit panels, but the electrical system continues to fail. The contact stated that the dealer was giving them the run around after extending the electrical system warranty to 100,000 miles. She also stated that there has been electrical failure since the vehicle was purchased. The purchase date was unknown. The current mileage was 50,000 and failure mileage was 5,000. The consumer stated the problem still exists. Updated 12/04/07
I have a chevy trailblazer 2005 and the lights keep flickering at night time when you increase and decrease power, I have reported it but nothing.
Lights flash dim then bright shortly after brake is pressed. The problem is intermittent.
My headlights flicker and the voltage meter bounces around. The flickering headlights are a danger to myself and others as those ahead of me think I am trying to flag them down.
Lights (internal and external) dim or flash when the gas is let off while driving. This is a very dangerous situation, people pull over, flash you back, and in one instance I police officer pulled me over. It seems to happen worse when the temperature is colder than 50 degrees. It's been to 2 different service departments and is still under warranty but they either negate the problem as normal or claim they can't replicate it. Some gm explanations refer to low speeds and brief drive times, I can say first hand it's happened every mile of a 300 mile trip, multiple times. I've read numerous identical complaints in your complaint database. Is it going to take a horrible accident to get you to make gm fix this problem?
My head lights and dash board lights dim and flicker. My fuel gauge is never correct it will show empty right after a fill-up.
Bought the 2005 trailblazer new, have taken it to have the flashing lights fixed on 3 occasions, but they could not duplicate the problem, so they could not fix the problem. Then while on a trip the switch went out, and was replaced at a dealer where the vehicle was not purchased, the lights quit flashing. Now the alternator has gone out, only 48,000 miles.
I have a 2005 chevrolet trailblazer and while driving at certain times the headlights will flash (bright -> dim -> bright) in a fast fashion. I believe that this could potentially cause an accident were people think you are allowing them to pull out in front of them, ect. I have taken it to my dealer and they say there is no fix for the problem. From what other people are saying on forums chevy says this is "normal". Due to the potential for an accident I believe these vehicles should be recalled. Here is a site I found regarding the issue http://www.topix.net/forum/autos/chevrolet-trailblazer/tucllqk4uif5na0ut. I'm having the same issue described here and I belief it causes an unsafe condition while driving at night.
On numerous occasions, I have had issues with the headlights dimming upon slowing from highway speeds. I was told that this was normal function, and could not be reproduced by the dealer. Today, I was informed by another dealer that the altenator bearings have gone bad, and the altenator needs to be replaced. Vehicle has 57k miles.
Basically my 2006 chevy trailblazer continues to go dead while driving or not. I have taken it to the dealership more than 5x and they still cant find anything wrong with it. Sometimes it stops in the middle of driving and at other times if I go nowhere it will not crank up. Since the purchase of my brand new vehicle the dealership has put in 2 new batteries which was not the problem as they stated. They have also kept my vehicle for at least a week to see what I was talking about which did occur. One day they were driving it the next day it wouldn't start. They jumped the vehicle and put it on the computer still got nothing. This is posing a problem for me since I have 3 young kids all under the age of 5 that I drive around daily. What might happen when the truck stop in the middle of traffic with my little ones!
Severe fluctuations in electrical power, resulting in dimming of headlights.
The headlights will dim when driving the vehicle. This can occur when idling but mostly happens when the vehicle is at highway speed. This has happened several times and two different dealers have checked the problem and performed all applicable tsbs and replaced the bcm with no difference in the problem. The lights will dim enough that when driving on dark country roads I am not able to identify the edges of the road. Tech support claims this is normal operation of the system.
