The speed keeps changing and it will not stay accurate and all gauges keep messing up.
2005 Chevrolet Trailblazer electrical complaints
Page 5 of 22: complaints 101 to 130 of 617, newest first, as owners wrote them.
Sir/ ma'am, I noticed recently in the news that several gm product lines have been plagued by faulty ignition switches causing the vehicle to lose power and/or cut out. I implore you to look into the trailblazers. I emailed gm while I was deployed (2012) and they gave me the runaround saying that it is not a documented problem, as expected. A simple internet search would show that a lot of other trailblazer owners have bad ignition switches/ electrical issues that cause the vehicle to lose power at all speeds. My wife lost power going about 35 MPH and I had my two children along with her. This is just one example, on one occasion. Granted, I do acknowledge this problem is intermittent, it still occurs at random and at all speeds. Gm tells me to go to a dealer and have them look at it. I refuse to pay gm any money to have a dealership rip me off for an ignition switch that is flawed and replace it with the same faulty oem style/model number. I have ran a scan tool looking for codes and it doesn't have any. Like stated previously, this is another line of gm that is plagued with ignition and electrical issues that gm refuses to take ownership of. The mileage I have entered is approximate. I cannot remember exact numbers, but it has happened for years, intermittently. When the vehicle has coasted to it's final destination after losing power, it starts up and drives normal again after it is put back into park. Also keep in mind that it doesn't show any check engine lights, indicating a problem or need of servicing. Again, please look into this product line as I know the result(s) will show that gm is liable and I don't want any fatalities because nobody spoke up about it.
Speedometer randomly parks on 0 MPH no matter what the speed is. The fuel gauge randomly indicates "e" or other inaccurate fuel readings regardless of how much fuel is in the tank. The car randomly stalls when stopped at traffic lights.
Tl* the contact owns 2005 chevrolet trailblazer. The contact stated that a burning smell was emitted from the control module on the driver's door. The contact mentioned that after inspecting the door she noticed that the wires were melted. The vehicle was not taken to the dealer. The manufacturer was made aware of the failure. The vehicle was not repaired. The failure mileage was 175,000 and the current mileage was 180,000. The VIN was not available.
The speedometer is stuck and will not move.
First my gas gauge started to malfunction. After purchasing gas my gauge would work sometime. Now it doesn't work at all. Then my oil pressure gauge went. Now my speedometer works most times but after driving a distance it does not register correctly. After shutting off and starting the car a few times it starts to work again. I've been told it is a common problem with chevys. My brother had the same problem in his chevy truck.
The heater levels started to go out. First 5, then 1 until it no longer worked at all. I got it repaired but the 5th level does not work any more. The left half of the radio/cd player no longer lights up. My gas gauge would only register a quarter tank and then would eventually dropped to empty. It no longer works at all. Most recently my speedometer will occasionally quit working or register the wrong speed. I have to shut the car off and restart until it works again. Also, my tachometer goes way up when I begin driving and the car seems to rev way up before it changes gears and jerks into gear. I questioned a mechanic about this, thinking it was the transmission, which it isn't. There doesn't seem to be enough power. I have constantly had issues with this trailblazer every since I purchased it. I also owned a blazer at one time and also had a lot of trouble with it. I should have known better to purchase another chevy, but never again!
My fuel gauge reads empty after I fill the tank with fuel. After driving some duration of time the tank will only read a quarter of a tank full. I find this to be a hazard because I travel for long distance trips and you are unable to get an accurate reading of the amount of fuel that is in your tank. I have read this to be an issue on multiple different websites with the same make and model and I believe that gmc should offer to pay full price and fix the issue because it appears to be a defect.
Tachometer and speedometer began acting erratically. Speedometer now acting properly but tach has never functioned correctly since. Researching online I have discovered that there are literally thousands of these instrument cluster units that are failing and eventually additional instruments within the cluster are likely to break. In fact, a class action suit forced general motors to recall/replace the instrument clusters on silverado pickups for similar problems. When I contacted gm about working with me to replace the failing cluster and they told me there were no recalls and to basically "pound sand." with so many documented instances of failure and gm's now documented history of avoid recalls even at the cost of human life I believe it is time for the federal safety agency to step up and bring pressure on gm to resolve this issue affecting thousands of owners who have been rebuffed in their efforts to have the automaker accept its proper responsibility for using inadequate or faulty materials.
Since I got the vehicle approx 5 years ago I began having issues about a year later. It started with my speed odometer gauge stopped working then over that following year eventually all the gauges stopped functioning. Little did I know that this was the beginning of my issues with the vehicle. My break lights will work off and on, my driver side windows works off and on, my blower stops working when ever it feels, a diagnostic test showed my throttle on has pedal never closes so I average 9 miles per gallon in gas mileage, the interior lights decide when to work and not, and the locks on their on causing me to get locked out of my car at times. This to me is clearly a electrical issue and have spoke to gm because I can't even trade the vehicle in to get a safer vehicle because no one wants it. Either way I worry of the safety for anyone in this vehicles and they need to be taken off the streets.

While sitting at a stop light, the fuel gauge stopped working. The gauge went all the way down to "e" and the low fuel level indicator appeared on the display. Now when I fill up the tank, the gauge reads empty and after I drive about 20-30 miles it will move up to about 1/4 tank but no higher and sometimes it will still move back to empty that slowly move back up. Also sometimes the oil pressure indicator will drop all the way down while idling or in park and the low pressure indicator will appear, but as soon as the gas is pressed, the pressure will go back to normal. Also, about 1 1/2 years ago, the keyless entry/alarm/back liftgate lock and license plate light all stopped working simultaneously. I was told that it is probably a grounding wire issue but not definitive. Now my liftgate will not lock at all.
While traveling we noticed the we were being passed excessively, we looked at the speedometer and saw that we were doing slightly above the speed limit. Out of curiosity we checked our speed against our GPS / smart phone and saw that we were doing 30 MPH under the speed being reported by our speedometer. After searching on the internet we found that 100's if not 1000's are having the same issue or even sometimes in reverse where it states that they are doing 120 MPH when they are only doing a fraction of that. In addition we have found that there has been a recall on this same part on other gm vehicles for the exact same reason but the trailblazer was excluded for whatever reason. How can not knowing how fast your actually going not be a major hazard especially with a proven history of failures.
Dash lights come on all the time .had it in to local dealer .we have took it in all the time they have replace everything they could to find problem.still didn't fix it. Warranted run out.even took in and pd for ourselves still not fixed lights come on now and stay on.can't keep taking in don't have money to take in.
Starting up my car last wednesday morning,I went to roll my window down on the drivers side and there was a hesitation then it stopped and I smelled something burning.from that point forward I was no longer able to roll my window down or up and lost all functions from that contact pad....in looking thru the varies recalls for this vehicle I noticed the recall for the drivers door module in 2006,2007. If this recall initiated with the 2005 trailblazer in 08/12, why is this model not included in the recall???? Why will I have to pay the $400 in repairs somehow this doesn't seem ethical. Especially if you knew this was happening in the 2005 chevy trailblazer...I am sure I am preaching to the choir but maybe you can provide me with incite as to the logic!!!!!!!!
Multiple gauges on the instrument panel stopped working. They include: fuel gauge, speedometer, voltmeter, and tachometer. The first to go out was the fuel gauge. Then speedometer, followed by the voltmeter and the tachometer about the same time. Chevy has fixed the fuel gauge issue by recall. But has not addressed the other gauges on the instrument panel.
I was driving down the highway in a rainy state with the driver's window partially cracked. Water began dripping in onto the driver window control panel, so I closed the window. A few minutes later I went to roll down my window and none of the controls worked. There was a faint electrical burning smell. All four window controls on the panel would no longer function as well as the heated seat buttons. The door lock still functioned as well as the window lock out button. I'm just glad this happened with the window up. Swapping the passenger side door control panel with the driver's side door control panel allows you to raise and lower the window, so it is the control panel that is defective. I see that the 2006 and 2007 models were recalled for this due to fires, but no recall exists for the 2005 fires as fires haven't been reported yet.
Saturday night (03/1/14) on our way home it started snowing heavily, the visibility was low and our windows were fogging up and the front heater blower went off on our 2005 chevy trailblazer and would not come back on. While trying to find a place to safely pull over we almost hit another vehicle because we couldn't see through our fogged up windows.. After we pulled over and turned the car off the blower motor came on and continued to run with the car off and the key removed from the ignition, so we re-started the car, and the blower went off and never came back on... Then today I went out started the car to warm up the engine and the blower came on. I drove to the store shut the car off and the blower continued to run so I re-started the car and turned it off again and the blower motor stopped. When I re-entered the car to go home the blower once again would not turn on at any speed. So I figured if I didn't have heat at least I had a heated seat but after about 5-10 mins the seat part of the seat got so hot it was burning my butt and thighs so I had to shut it off. Then about 1/2 home the blower just started blowing again, I pulled into the gas station shut the car off and the blower motor once again continued to run with the car off and the key out of the ignition so again I put the key in started the car then turned it off again and the motor stopped. This could be a very serious issue with not being able to defrost the windshield/windows in these hazardous driving conditions< plus not having heat in below zero temps is a health hazard as well. ( since we live in such a cold snowy state).
I have any issues with my fuel gauge and dash reading for years now. I thought it was an issue with just my truck but in reading other complaints it seems as there is an issue. I bought my truck new and currently have 178,000 miles on it. I was told bythe dealer that the gas gauge issue would not be covered as it's 10 years or 120,000 which every came first. My dash board has not been working for some time first it was the speedometer and then the oil and other's components soon followed.
I just purchased this vehicle yesterday from a dealership. They filled the gas tank up before I drove it off the lot because, they said, "the gas gauge isn't working." I was looking up what it could be and noticed there was a lot of people with complaints of this, 668 people. I suppose I'm the 669th person. There wasn't a recall that I could find, but investigations were being done?
Vehicle's headlamps will power surge, dim while driving periodically. Fuel sensor showed constant empty until repaired by the recall. Vehicle will occasionally surge forward revving on it's own at random times. The blower resistor pack has burnt up twice, the blower motor has been replaced as well as the melted wires.now the vehicle will not start. The power windows, locks, radio, dome lights, dash lights are inoperative and the vehicle will not attempt to turn over. Seems like this vehicle has had a lot of electrical issues.
Driving at a low speed through a residential area the engine would serge between 2k RPM and 4k RPM. If surging is allowed to persist then it is followed by the vehicle's power steering shut off ultimately ending in the engine shutting off. After vehicle is restarted the cycle starts again after a short period of driving.
First speedometer quit working. Reads "0" all the time. Then the gas gauge quite working. Reads empty and the light is on all the time. Then the oil gauge also quit working. This happened all within about 6 months of each other.
Driving on the highway to the shore my speedometer increased to 95 MPH. When we parked it was stuck on 10. Since then it has happened many times. When I park I have to check what it stops at. Sometimes, its 10, 20, 30, etc. I have tried disconnecting the negative battery cable and that helps as a temp fix. My dealer says there is no recall, but I saw online a class action suit against gm, but not for trailblazers. This is a gm issue and I don't have the money to get it fixed. Updated 03/11/14
I was driving on the highway when I slowed down & stopped for an accident ahead of me. I did not slam on my brakes and I did not go over any bumps that would jar the vehicle. I was stopped for approximately 20 minutes. When I began accelerating I noticed the speedometer was no longer accurately reading my speed. I was doing around 50 MPH, but my speedometer was reading 22 MPH. I tried turning the car off once I got home, then restarting it, but it was still reading 22 MPH. When I drove it the next day, it started out reading 10 MPH, and has varied since then, but still not reading accurately.
I went into town to grab dinner and as I am driving along, my headlights shut off. The only thing that remained on, were the orange turn signal lights. I frantically turned the headlight knob on an off and nothing happened. I was looking for a place to turn off the highway, however it was night time and I had no headlights. I ended up pulling over to the gravel side of the road, and turned the car off. Now I am stuck on the side of the highway at night time, with no working headlights. I turned the car off and got out, tapped the headlights and looked for any physical damage and did not find an answer. Upon starting the car again, it sounded like someone had turned on a vacuum cleaner. The noise pitched up for about 5 seconds before pitching back down. After re-starting the oil pressure gauge moved from its normal position at "12 o'clock" to an abnormal "6 o'clock". I tried to call onstar for a vehicle diagnostic, however now my radio would not work either. I tried the headlights again, and they still would not turn on. I turned on my high beams, and proceeded back home. While en route my speedometer was reading 10mph over my actual speed. When I pulled into my driveway and turned the car off, the speedometer stayed at 10mph. I find it very hard to believe that all of these things happened all at once as a coincidence. This is a huge safety concern as I lost the ability to see at night, as well as the ability to monitor my speed all while trying to drive. Not to mention all of the motorists who were blinded by my high beams on the way back.
While driving my vehicle, the speedometer stops working. It works when you start the car, then when stops are made, it stops working altogether and goes to zero. I have researched the internet, and this is a huge problem for this vehicle, and gm should have recalled this faulty part years ago. When I took it to get repaired the service place said it was a cluster that would cost over $500 to get fixed. Once again, this is a huge problem and gm should take care of ts customers.
My speedometer needle would read the wrong MPH and start to bounce all over the place and about a week after that started it just wasn't working all together and now doesn't move at all.
Bought this vehicle used in oct 2010. Not long thereafter, noticed the speedometer wouldn't work all the time - normally it works when I first start driving but when the vehicle warms up, it stops working all together. I think it's a safety issue if you do not know how fast you are going. The cruise control also doesn't work once in a while. Most of the time it does, but occasionally I can't get it to go on at all.
Tl* the contact owns a 2005 chevrolet trailblazer. The contact stated that the speedometer failed to operate normally without warning. The contact also mentioned that the fuel and temperature gauges failed to operate. The vehicle was not taken to a dealer or independent mechanic. The vehicle was not repaired. The manufacturer was notified. The approximate failure and current mileage was 48,000. Updated 11/29/13
The fuel gauge stopped working then all the other gauges of the instrument panel began intermittently then permanently stopped working. Aside from the battery gauge, the least important of them all.
