2005 trailblazer alternator voltage dips alot as you drive. Radio does not work unless it is 100deg, then only one speaker works. Gas gauge reads empty after I filled up. Ignition is very hard to turn, you have to keep inserting and removing key until it frees itself.
2005 Chevrolet Trailblazer electrical complaints
Page 14 of 22: complaints 371 to 400 of 617, newest first, as owners wrote them.
Burning smell coming from the A/C. Speed 4 and 5 both quit and now the whole thing has stopped working. This will be the third time is has been replaced and the dealer I take it to tell me this is a common problem on 2005 chevy trailblazers. Blower motor resistor is burnt out and the harness (which would cost about $200). They said that this was another common problem for this car model.
Speedometer on my 2005 was acting up and then stopped working all together...this is a safety issue. And it is amazing to me how many people have complained about this, and nothing is being done with this problem. My husband has a 2005 chevy impala and his speedometer stopped working and his gas gauge. Why is this continuing with chevrolet...someone needs to put a stop to this nonsense. Oh...and by the way I have already had the cluster replaced just 2 years ago because of a winding noise and then a year later it acts up...hmmm...did they really replace it? Take a look at this website for more complaints: http://www.carcomplaints.com/chevrolet/trailblazer/2005/electrical/speedometer_gone_haywire.shtml.
My 2005 chevy trailblazer ext 4x4 has a short in the electrical that runs the AC/heat fan. Chevy acknowleged there is an issue and have created a service bulletin on how to address the issue. But say it is up to the car owners to pay for the fix. This has caused my electrical wires to melt together and I can smell the smell of burning plastic almost everytime I drive the car and have on the heat for more than 10 min. I am afraid my car is going to catch on fire.
I have a 2005 chevy trailblazer ls and I have two complaints regarding part defects that should be investigated. 1. The speedometer sticks. I can be driving along and all of a sudden my speedometer is not moving at all. This is extremely dangerous being that I have no clue how fast or slow I'm going. 2. The fuel light gauge/sensor just completed stop working. The gas needle does not move at all, I have no idea how much fuel is in the tank. This is also extremely dangerous!. I have many friends that own chevy trailblazers who have encountered these same issues and I feel that chevy should fix the problem. I have also read many blogs online where trailblazer owners are complaining of the same issues so this is clearly a problem for thousands of trailblazer owners. I hope that this complaint will help jump start an investigation of these defects, because it is a major problem! I have contacted my local chevy dealer and they stated that it will be $1,200 to fix this issue.. This is outrages being that the problem is something that was caused by chevy.
Fuel just stopped working, driving down the road and headlights start dimming gauges go all over the board. Put a new battery in, changed the alternator and it continues to do this. Check engine light keeps coming on for oxygen sensor had that replaced 1 year ago needs replaced again.
2005 chevy trailblazer instrument cluster going haywire, speedometer saying you are going 80mph while you are not even moving. You have to guess on how fast you are going.
Fuel gauge started functioning erratically - would go from empty to full or just start going between full and empty floating around. Eventually it just stayed on empty even when I had just filled up. From the time the problem started till it stopped working was only a matter of weeks. Now my oil gauge stopped working also.
Speedometer suddenly quit. And will not read over 25 MPH. Luckily cruise was set so I know my speed. Odometer still counts correctly. Estimates for replacement of instrument cluster are %500 and up. This is a known safety issue with over 1000 complaints.
2005 chevy trailblazer...speed/gas/oil/basically all gauges are messed up...I see online there are many complaints as to this issue...this causes a safety issue for my kids and myself...if I can't depend on my gauges then what do I do...
Speedometer stops working , very erratic behavior. Will work for few minutes at a time.
Speedomter failure.
Speedometer does not work on 2005 chevrolet trailblazer and 2005 silverado.
My speedometer stopped working while I was driving down the street near my house, driving at 45 MPH when it went out. Since then it has not worked and I never know how fast I am going. I called chevy because I had read online that gm is extending the warranty on quite a few cars and trucks that are having this issue and as long as your car has less than 70k miles and/or 7 years old they will fix it at no cost to the car owner. When I spoke to the representative she said that my trailblazer was not included and then made me an appointment with the local dealer. Although it was nice to make the appointment I still have to pay the 200 dollar diagnostic fee and the 700 dollars to get it fixed. I see so many complaints online with my year and make that it is inconceivable that this is not a recall.
I just bought a 2005 chevy trailblazer ls. Speedometer is going haywire. Needle points straight down and slowly ticks backwards. When im stopped it normally shows im going 60 MPH and when driving it goes into the 100's and then way passed the 120 MPH mark. Also my oil pressure gauge needle is way passed full and is almost facing straight down. Apparently there's been a ton of people with this exact problem and it should be a recall but apparently gm won't do anything about it.
Just as so many other 2005 trailblazer owners, neither my speedometer or gas gauge has worked for some time. I refuse to pay the cost to have these repaired at $500 + on a vehicle that I feel is still new. To deal with the problem, I purchased a garmin which will tell you what speed you are going and have figured out with my gas gauge that when I have gas, my low fuel light stays on and when I am getting low, it goes off. So I work backwards, when my low fuel light goes off, I fill my gas tank and monitor the miles I have driven. Why is gm not held responsible for this problem, it is obviously widespread.
I have a 2005 chevy trailblazer with 50,000 miles. Starting a couple months ago the speedometer regularly malfunctions and gives me the wrong speed. Gm refuses to correct the problem and tells me I have to spend $125 to diagnose the problem and possibly over $500 to ultimately fix the problem the problem has happened to many 2005 chevy trailblazer owners and nothing has been done.
Just adding another 2005 trailblazer speedometer to the growing list of failures. Speedometer quits working so many people are having the same problem . 450.00 to get it fixed I need a bail out to fix it.
My speedometer in my 2005 chevy trailblazer has started not working on occasion. It will work only after I turn the vehicle off and let it sit a bit. This is very disturbing to me due to the fact that I am a very safe driver and when this happens I feel I am a threat to others on the road.
The chevrolet trailblazer has a history of the gauge cluster in the dash being defective. It seems that many consumers are having problems with them going out. When this happens the fuel gauge and speedometer do not work. This is a huge problem and it seems that chevrolet does not feel the need to help the consumers correct this problem. We have checked into the time an cost of the repairs and it is very time consuming and expensive for the consumer.
The speedometer on my 2005 chevy trailblazer malfunctioned saying I was going faster than I really was. This has happened 3 times; the first time on january 28th 2010, and twice on the night of february 4th 2010. It appears to be getting worse each time. The speedometer will increase during acceleration and not move for deceleration. With each deceleration and subsequent acceleration the speedometer continues to increase until you hit max speed of 120 MPH. This is a large danger for frequent freeway/highway traveling considering the vehicles approaching from the rear and I have no way of knowing how fast my vehicle is really going. The only way that I have found to reset the speedometer, is to stop and shut off the vehicle, then restart the vehicle. However, this must be done multiple times, sometimes up to 10 times or more. Each time the vehicle is shut off and restarted, the speedometer will reset approximately 5 MPH. This evening I had to restart my truck 12 times to get it back to zero. The first time this happened, a friend was driving for me, and this malfunction has resulted in a speeding ticket.
1. Driving on the highway, minding my business... 2. Speedometer is stuck at 0 when I'm driving, says I'm going 100+ when I'm at a standstill, & is never accurate any more. Happens every time I drive now. Already one speeding ticket- 55 in a 40 and I had no idea. 3. Nothing done yet- dealer says cost will be $500+.
I own a 2005 chevy trailblazer. On highway 61 near troy, mo, there is a speed radar set along the road to display vehicle speed to drivers. On 2 occasions, my speedometer showed speeds of 60 MPH when the radar display showed 40 to 45 MPH and on 3 occasions, my speedometer indicated speeds of 60 (the speed limit), while the radar displayed speeds anywhere from 75 to 85 MPH. I was going 15 to 25 MPH faster than the speed limit, but did not know it according to my speedometer. This does not happen all the time, but has occurred at least 6 or 7 times over the past year at different locations. I have found that when I stop the trailblazer, when the speedometer is registering low, the speedometer needle will actually move below the 0 MPH. On those occasions when my speedometer was registering high, when I have stopped the vehicle, the needle will still be showing 25 to 40 MPH! My fear is that on one of those occasions that my speed is actually faster than indicated, my speed my cause an accident. I have found that after stopping the car and turning it off, if I just turn the ignition key to run without starting it several times, the needle will gradually reset itself back to 0 and I won't have any more problems for a while. I have had an estimate to replace the instrument cluster for $500 to $600, but I feel this is a recall problem that chevrolet needs to take care of. I have read numerous complaints from other trailblazer owners on the internet, this is what moved me to file this complaint.
All gauges on my 2005 chevrolet trailblazer have failed. It appears to be a very common problem, and many other chevrolet models using the same gauge cluster have been recalled, but not the trailblazer.
I have a 2005 chevrolet trail blazer that the tachometer and speedometer fail to work. Doing research on the web this seems to be a common problem. Why is there not a recall for this safety hazard?
The speedometer malfunction began on january 11, 2010. First the speedometer appeared to be stuck at zero. Now it has gone up and past the highest MPH reading on the 2005 trailblazer. There has been a recall on the other chevy trucks with the same speedometer but has not included the trailblazer. How can one safely drive when you don't have an accurate reading on how fast the vehicle is traveling?
Tl*the contact owns a 2005 chevrolet trailblazer ls. He stated that the instrument panel displayed the incorrect fuel level, mileage, and speed traveled. The dealer stated that the instrument cluster needed to be replaced. There were no recalls on his vehicle. The dealer stated that the repairs would be at the owner's expense and that the panel could possibly fail again. No repairs were made to date. The failure and current mileages were 57,413.
I just purchased a 2005 chevrolet trailblazer last night 1/25/10,today the speedometer and the gas gauge do not function. The speedometer rotates when it want all the way around the dial. The dealer states it is an as is car and they are not responsible. I researched today and found way too many complaints on this issue on this model. Why isn't gm adding this to their recalls on other models with the same issue?
Speedometer stopped working.
Absolutely nothing out of the ordinary, regular driving conditions. The speedometer on my 2005 chevy trailblazer does not work. It is continuously reading the wrong speed and skips when moving. It will go all the way to 120mph and then beyond when I know I am only going 50. At 55 to 65 miles an hour the speedo sticks then continues to climb. The only way I have figured out how to change it back is to turn on and off the vehicle until it resets back to 0. This takes for ever and is damaging to the vehicle. It only goes back 4 MPH at a time whenever I have to do this. It happens almost everyday now and I am livid with my vehicle. I will never buy a gmc again.
