Tl*the contact owns a 2004 chevrolet trailblazer. The contact stated that the headlights and interior lights would dim intermittently. At times, the headlights are so dim that he can hardly see the road. The dealer was able to duplicate the failure, however, they were unable to provide a remedy. The contact was advised not to drive the vehicle at night. The current mileage was 29,000 and the failure mileage was unknown. Updated 02-01-08.
2004 Chevrolet Trailblazer electrical complaints
Page 21 of 22: complaints 581 to 610 of 627, newest first, as owners wrote them.
I have owned this vehicle for 2 1/2 years. The first problem was noticeable only at night when the windshield glare was so bad on the freeway that I could not see very well. We had the windshield replaced. The second problem has been on-going for the past six to eight months. The speedometer sometimes works, but is usually not very correct, and most of the time it just picks a number and sits there for several days, whether the car is running or not. I usually use the rpms to figure out how fast I am going until my mechanic can fix it for more than a week at a time.
Daily failure of seedometer on my 2004 chevrolet trailblazer. This was in addition to failure of the fuel gauge. The speedometer problem was inconsistent and made me question the actual speed at every moment and made me measure based on other traffic. It is a very distracting way to drive with all gauges moving at times and then returning to a fixed setting. I had the clusterboard replaced by the dealer who claimed this was not a common problem. Instrument panels on 3 year old cars do not fail unless there is a manufacturing problem. Please prevent accidents in the future this is not a safe way to operate a vehicle.
Tl*the contact owns a 2004 chevrolet trailblazer. She stated that the speedometer and the gas gauge works intermittently. When making a right turn she hears a humming noise. The dealer stated that they were unable to duplicate the problems however; they suggested that the instrument panel be replaced. The dealer has not made the replacement. The failure mileage was 35,000 and the current mileage was 49,000.
Insturment panel not working properly. The speedomoter started out showing random speeds and nowwa s permenantly stuck at 89 MPH no matter if the cawass running or not. The RPM gauge also doid not move. This should be a recall, there appearse dto be a large problem with this issue.
2004 chevrolet trailblazer speedometer is malfunctioning. Gives a 100 MPH reading when going 60. Sometimes doesn't work at all. I know there to be thousands of similar complaints about gm speedometers. Gm should recall this and not be afraid to stand behind its product.
Most dashboard gauges failed on the 2004 chevrolet trailblazer. Total loss of fuel gauge, amp gauge, temperature gauge and oil pressure gauge. In addition to these failures odometer did not work properly. Also, other driver information computer items did not function. Abs, parking brake and battery lights illuminated. After a while of driving all dashboard functions returned to normal. This has happened several times in the past few days.
My speedometer sometimes reads about 20 MPH off then won't reset when I turn the vehicle off. It just stays at 20 MPH...then sometimes it does reset and works fine. I took the vehicle to a chevy dealership and they said that since the problem wasn't happening at the time I took it in they couldn't do anything except re-program the speedo. That didn't help, it happened again after that.
Speedometer does not work, so I do not know how fast I am going. The temperature gauge sometimes says my engine is too hot when it is not, so now I am not sure about the status of my engine's cooling system. This is an ongoing problem. I am extremely concerned and discovered on the internet that many people are having this problem.
Intermittent headlight and voltage problems, the vehicle is a 2004 trailblazer, the problem began in the fall of 2004...headlights and voltage gauge would dim and drop, would continue to do this intermittently...dealership replaced the alternator twice..also the dash has been replaced once due to the voltage spikes caused by this...the last time I took it in the service manager told me that gm had issued a bulletin on this saying it was " the nature of the beast" that it was caused by a secondary smog pump that was supposed to come on only when the vehicle was 1st started...but could also keep kicking in and out causing a severe voltage draw...my truck now has 50,000 miles on it, am afraid these voltage spikes will take out another dash, I feel gm has a serious defect with this and feel this a serious safety issue as the headlights all but go out at low speeds, the dealership here has done all that gm will allow them to do according to them.
Speedometer faulty and showing wildly inaccurate speeds. When driving on a highway, the speedometer will range from 10 MPH to 120 MPH! While conducting research online, this appears to be a major widespread problem with gm trucks and they have not taken any action to correct this dangerous situation. My vehicle is recently out of warranty and the repair will cost over $600.
The speedometer in my 2004 chevy trailblazer began to show the wrong speed at about 45,000 miles. The needle would increase with speed as it should have but would not go back down again like it should. Then it quit working altogether and the needle just hangs limp. We had the speedometer diagnosed at another facility since this occurred around the holidays and gm dealers could not get us in. My wife has been commuting 20-30 miles daily having no idea how fast she is going because gm refuses to correct the problem. I have found hundreds of similar stories after researching it on the internet. Every person I know with a large gm vehicle has had to replace it between 40,000 and 50,000 miles. The facility that diagnosed the problem said that the speedometer head was stripped and the dealerships know the price of this part off the top of their heads, presumably because they replace many of them.
My 2004 chevy trailblazers speedometer started malfunctioning. It will register speeds 25-35 miles per hour over actual. It also does not operate smoothly but jerks to the next number. Very dangerous, and very expensive to fix. It appears that this is also happening on the envoy, tahoe and avalanche models. This should be qualified as a safety recall.
Odometer failure after 81,000 miles... Odometer will lock on different speeds, from 10-40- 110 MPH even though I am not traveling that speed. My mechanic says that this part needs to be recalled because he has had to replace so many chevrolet tahoe and trailblazers with the same problem. This part can run over $300.00 sometimes.
Speedometer suddenly started reading randomly, usually 10-15 MPH too high. Intermittent.
Dash warning lights come on/stay on/go off randomly. Additionally, on four separate occasions, decreased engine power has occurred. Shutting vehicle down with a restart has always solved the "decreased power" issue. But dealership & an independent garage cannot fix due to "no codes stored". Warning light involved are: service engine soon, oil change due and reduced power. This is an ongoing problem having started almost as soon as we took delivery of vehicle new with 250 miles .
Headlights blink while driving and speedometer and tachometer stopped working.
On 8/1/06 I was awaken by a neighbor at 1 am saying my car was on fire. The fire department was called but the entire interior was destroyed. The fire department said it had to have been an electrical malfunction. The vehicle had been parked since 8 pm that night and it was locked. There was no sign of forced entry and no sign of any other reason for the fire. The car was purchased new in 10/04 and had less than 30,000 miles on it. I used the roadside warranty to have it towed to a dealer but the dealer refused to have anything to do with it. It took two weeks for gm to send a fire investigator out and their investigator said he couldn't determine the cause of the fire. I filed a complaint with the vermont state attorney's office but gm did not respond to the complaint. I had electrical repairs done just a few months after purchasing the vehicle too and the stereo system had stopped working just a month before the fire. The car is still sitting at the dealership. I did not have collision insurance because the car was paid in full and my current finances did not allow me to maintain anything more than liability insurance. So now I have no vehicle and this is tough with 3 young children. Gm refuses to honor their warranty and insists that this model vehicle doesn't have electrical issues. It's time someone made gm honor the warranty they charge for when you purchase a new vehicle.
The speedometer & tach do not work properly they read wrong or not at all. You can be driving at 50 MPH you think, but it might be 60 or 70. When I called the dealer service the rep seamed to know right away what the problem was. Cost $400.00+ to fix.
This car has had problems before cutting off for no reason. The dealer where I bought it from said that "they could not find anything wrong with it". Now the car gauges and dashboard lights do not work properly. They sometimes do not work at all and after a while turn on.
Speedometer started acting erratically. Either posts no speed, or shows a speed that is obviously not correct. Turning off car, and restarting corrects the problem for the moment.
I have a 2004 chevy trailblazer. Early last month I discovered my speedometer meter not stopping at 0 MPH when I approached a traffic light. It stopped at 20 MPH. This meant the speedometer was indicating a speed faster than I was actually going. When I turned the vehicle off that evening and back on the next morning, it reset and returned to 0 MPH. As the month progressed, the speedometer indicator continued exhibiting this problem. This problem has caused the indicator to exceed passed the 120 MPH indicator. The only resolution has been to continuously turn the car off and back on. Depending on where the indicator stops will dictate how many times I'll have to turn the car off and back on to get the indicator back to 0 MPH.
I parked and turned off my car and it burst into flames. I had absolutely no warning, no warning light came on and I had no problems with the car at all until the fire.
The speedometer and tachometer gauges on the dash don't work. The get stuck at say 50 MPH and 7000 rpms. So you don't know how fast you are going or what the true RPM's are. Than it takes about a week and your dash will start working again. My mechanic had 4 other trailblazers at his shop with the same issue. It cost 400.00 to fix and you are with out a car for two days.
Dt*: the contact stated after driving the vehicle for an hour to an hour and a half, the controls on the door and steering wheel became hot enough to cause a minor burn to the contact. The control panel on the radio also blacked out and the clock reset itself. When the vehicle was taken to the dealership, the computer stored no codes and the problem could not be determined.
Car died on exit ramp of 290 and thorndale. Pushed car to side of road where we noticed smoke coming from under hood. Upon opening hood saw fire coming from filter under air cleaner compartment. Flagged down police officer who helped put out fire with fire extinguisher. Had car towed to advantage chevrolet who said they had never seen anything like this and perhaps a cigerette got sucked in and started the fire. Contacted gm who sent out a rep and could not explain fire so he concluded gm was not responsible under warranty because the car must have sucked in some foreign object and it was not a mechanical failure. Car was repaired under my insurance, who is fighting the claim. Parts replaced were air cleaner compartment, ducts, clamps, sensors, snorkel, element etc. Was told old parts were in back of car, but when we looked parts were missing. Dealer still looking for parts. No one has yet to address why car died in the first place.
I own a 2004 trailbrazer that have the same problem as the gm recall on lose brake-lamp function or have brake lamps that are always on. On vehicles with cruise control, that function also becomes inoperative. . The federal safety agency contacted gm to inquire about the issue after receiving three complaints, and the company issued the recall in response, adler said.
We have a problem with our vehicle 2004 chevy trailblazer, purchased new. It has a problem where it will shut down while driving. It may or may not stall, but it goes into reduced engine power with all service engine lights on. It did stall one particular time while my wife was driving it. She was on a steep hill and the vehicle stalled and rolled backward down the hill. It was vary difficult to steer and brake for her without the power steering and braking on. Luckly no one was behind her. This vehicle has been to our dealership for the 5th time now and twice to another dealership for the same problem.
While driving at night, I noticed the dash lights dim and headlights dim at the same time. The lights then immediately flicker back to normal nighttime lights. It appears they are flickering between daytime and nighttime settings. When I took the car to the dealer, they could find nothing wrong.
2004 chevy trailblazer electrical system has serious problems. In the rather short time I have owned it, it has been in the dealer repair 7 times for the same group of problems. The outside mirrors keep pointing to the sky randomly causing brief confusion when they are needed for safety. The pre-set memory keeps clearing itself. The headlights and dash lights often go very dim and flicker causing distraction to the other drivers and fear in the driver operating this vehicle. The driver's side heated seat stopped working. The passenger side door window controls randomly stop working. Turning off the vehicle and restarting it is the only way to correct it. All of these items have been looked at by the dealer but no solution has been found. Several computer reprogramming and parts have been replaced but the problems still remain. The dealer does not acknowledge that information posted on the internet by other owners of this vehicle is valid. That is bull~h@t !they seem reluctant to continue troubleshooting it. My greatest fear is that it ends up burning to the ground like many other owners have reported. Something has to be a common problem for all of these electrical issues with these vehicles.
