First was the right tail light caught fire and blew fuses, then I get power surges that cause the vehicle to accelerate randomly at the worst times and/or will also stall out, which can be potentially very dangerous or end in a fatal accident, it drops in rpms and lights dim then it accelerates... And the last thing is that the fuel gauge fluctuates dramatically and you can never tell how much fuel you really have... Drive 10 miles at quarter of a tank and it either stays close to the same spot or drops and the light comes on for low fuel.
2005 Chevrolet Trailblazer electrical complaints

Tl* the contact owns a 2005 chevrolet trailblazer. While driving various speeds, the contact noticed that the speedometer would fail intermittently and the oil gauge failed completely and would not provide a reading. The vehicle was taken to the dealer for diagnostics where the technician advised that the instrument panel cluster had to be replaced. The vehicle was not repaired. The approximate failure mileage was 81,000.
The speedometer does not reset itself when the vehicle slows or stops. Instead, it resumes from a higher speed. For example, if you are traveling at 45mph and stop at a stoplight the speedometer may drop to 40mph upon stopping. Then when you resume traveling it starts from 40 instead of 0 so the speedometer shows you are traveling 60 when you are going 20, 70 when you are going 30 etc. When you stop again it will come to rest at an even higher speed, until eventually the needle shows over 120 MPH when the vehicle is sitting still! I have done some investigation on line and this appears to be a fairly common complaint from fellow owners. General motors apparently dopes not consider this a safety issue and as such will not pay for the repair which is $500 or more. I'm not sure how not knowing you rate of travel is not a safety concern for them, but it certainly is to me.
Tl* the contact owns a 2005 chevrolet trailblazer. The contact stated that while driving approximately 75 MPH, she noticed that the speedometer would display higher speeds. The vehicle was taken to an authorized dealer and they stated that the speedometer needed to be replaced. The vehicle was not repaired. The manufacturer had not been notified. The failure mileage was approximately 51,000.
Tl* the contact owns a 2005 chevrolet trailblazer. The contact stated the entire instrument panel would operate intermittently. In addition, the fuel gauge and odometer displayed inaccurate readings while driving. The vehicle was taken to an authorized dealer who stated the instrument cluster would need to be replaced. The vehicle was not repaired. The approximate failure mileage was 54,000.
Fuel gauge has failed. Gauge reads empty, even though fuel tank is full. There are sporadic fluctuations of the needle, but gauge is no longer reliable for determining fuel level in the vehicle. Numerous reports of similar failures in the chevy trailblazer / gmc envoy line of vehicles indicate it is a failure of the fuel sending unit.
Gauge cluster inaccurately displays fuel level, oil pressure and temperature. Occurs daily.
I have a 2005 chevy trailblazer. In the last few months the blower for my air/heat/defrost has been acting up. Sometimes it works and sometimes it doesn't. Just recently in the last few days it stopped working completely. I can't use my defrost to clear my windows or use my air or heat. I was told the resistor and harness (which starts to melt and burn) is causing the blower not to work. I checked with mechanics and on line and there isn't a recall on the resistor and/or harness. There are a lot of complaints and was told that it is happening in all chevys.
2005 chevy trailblazer. Heat/AC stops working on 5..then eventually 4 stops and so on until none of it works. The wires get to hot and melt together. I know so many people that have had this problem yet chevy still doesn't recall it!?
During routine driving around keene nh the speedometer stopped working. Nothing has been done yet.
Tl* the contact owns a 2005 chevrolet trailblazer. The contact stated that the speedometer, fuel gauge and the battery voltage indicator on the instrument panel were all operating erratically. The contact spoke with the manufacturer and was told that the vehicle did not fall under the age or mileage requirements to be repaired. The contact was told by the dealer that the instrument cluster was failing. The failure mileage was 89,442 and the current mileage was 108,000. Updated 09/28/2011
About a year ago my speedometer would randomly show a loss or gain of speed. About 8 months ago it quit working all together. It does not register in the numbers. During the same time I ran out of gas twice when my gage had registered fuel and the low fuel light was not registered. It has since quit working all together. I recently called to ask how much an instrument cluster would be to replace and was given a total of about $600.00 this is a very disheartening situation. I have read all other complaints on line and they say the same thing. I believe that this is a very serious issue and am extremely disappointed that it hasn't been resolved by the company.
Tl*the contact owns a 2005 chevrolet trailblazer. The contact stated the fuel gauge and oil gauge failed and no longer displayed readings. The contact stated that they did not know the oil pressure or the amount of fuel in the fuel tank. The vehicle was not taken to have the failure diagnosed or repaired. The failure mileage was unknown and the current mileage is 71,941. Updated 07/21/11 *bf updated 07/25/11
Erratic fuel gauge, reports no fuel even when fuel available, reports 1/4 tank of fuel available and no fuel may be available or I may have just filled the tank; also reports no fuel or low fuel when tank has been filled. Vehicle has stalled out and would not start; was out of fuel but gauge indicated 1/4 tank of fuel. Oil gauge has also become erratic; and goes from showing no oil pressure to low oil pressure to very high pressure. Have to pull over immediately and check oil level at side of road or where ever available to do so at time. Not always safe area to pull off. Both issues create very hazardous and dangerous situations for the driver and passengers in the vehicle.
Tl*the contact owns a 2005 chevrolet trailblazer. The contact stated that the gasoline gauge and the speedometer failed. She was unable to see how fast she was traveling or whether or not she had a sufficient amount of fuel in the vehicle. In addition, the headlights would also shut off on an intermittent basis which caused her to change the bulbs frequently. The vehicle was not inspected by a dealer nor had it been repaired. The manufacturer was contacted and advised her that there were no recalls on the vehicle. The failure mileage was approximately 104,000.
1.) nothing I can think of that I did caused the problem to start. 2.) the speedometer in my 2005 trailblazer simply does not tell the correct speed. Nearly ever time I drive the tack will either stay at 0 or will go up to and beyond 120 MPH. I have resorted to using my GPS to tell my speed, but it is a large inconvenience to me and may others that I have found online. 3.) I have just begun to research the problem so I have not done anything to fix the issue.
Tl*the contact owns a 2005 chevrolet trailblazer. While driving approximately 35 MPH the speedometer began to move erratically. The speedometer reading fluctuated and displayed the incorrect speeds. The fuel gauge also did not display the accurate amount of gasoline in the fuel tank. The vehicle was taken to the dealer where the technicians stated the fuel level sensor and the instrument cluster needed to be replaced. There was an open investigation under the federal safety agency action number: dp10001 (fuel system, gasoline:delivery:fuel pump) which may be related to the failure. The manufacturer was made aware of the failure and agreed to cover the repair cost for the instrument cluster. The vehicle was not repaired. The approximate failure mileage was 50,000.
I have a 2005 chevy trailblazer that I just found out needs a blower motor resistor replaced. This sounds like a very common issue with the chevy vehicle. The wires were melted by the connection which could easily spark a fire. With three young children in car seats a fire inside the cabin of the vehicle would be disastrous. Please make them recall this and take care of this issue. Thank you,
Tl* the contact owns a 2005 chevrolet trailblazer. While refueling the vehicle, the contact noticed that the empty fuel warning light was illuminated on the instrument panel. The contact stated that the fuel gauge reading was inaccurate and would fluctuate sporadically. The vehicle was taken to two different independent mechanics. The mechanic stated that the entire instrument panel would need to be replaced. Also, the contact stated that the speedometer reading would also fluctuate intermittently and provide inaccurate readings. There was a concurrent investigation for the failure under the federal safety agency action number: dp10001 (fuel system, gasoline:delivery:fuel pump) that the contact believed could have been related to the failure. The vehicle was not repaired. The VIN was unavailable. The approximate failure mileage was 58,000.
Tl* the contact owns a 2005 chevrolet trailblazer. The contact stated that the entire instrument cluster failed. The dealer was not contacted and the manufacturer was not made aware of the failure. The vehicle was not repaired. The failure mileage was 80,000 and the current mileage was 102,000.
The speedometer on my instrument panel cluster malfunctioned. Problems included the needle sticking in one place, not moving down when decelerating, and even spinning to the "6 o'clock" position below the gauge. I called chevrolet to find out information and they were not able to offer me any help or reimbursement assistance.
Gas gauge on vehicle does not give accurate gas level in tank. Readings on the gas gauge fluctuate with vehicle in park, gives empty warning ding when tank is full, and readings on gauge fluctuate erratically at times while vehicle is in motion. Have been stuck on highway with an empty fuel tank a couple times with my three young children in the car. It is my concern that this may cause a fire in vehicle so I no longer put my family in it.
Gas gauge reads empty regardless of actual fuel level. It started out as an intermittent, and periodic event. It then would dependably happen immediately after fill-up at the pump. Now, it is continuous.
I have a 2005 chevrolet trailblazer with what appears to be a faulty gas gauge. The gas gauge suddenly stopped working in late-2010 and now remains on 'e' most of the time, regardless of how much gas is in the tank. Although infrequent, the needle has at times began to jump from 'e' to in between a 1/4-1/2 tank. The consequences of this failure are that I have to closely monitor my mileage at all times, reset the mileage each time I refill my gas tank, and notify any persons other than myself that drive my vehicle that the gas gauge does not function properly. Nothing has been done to correct the failure as the part is quite expensive, I do not feel a gas gauge should break so easily on a 2005 vehicle, and I am hoping the vehicle will eventually be recalled for this specific piece of equipment as I know several other people having a chevrolet trailblazer who have encountered this same problem.
Yes my fuel gauge does not tell me the correct fuel amount in the fuel tank ,when I fill my tank up with gas. The gauge goes to empty and when driving it goes back and forth between empty and full its just a inconvenience not knowing if you are going to run out of gas or not there should be a recall on this vehicle because this seems like a ongoing problem also ill be driving and the headlights will just start flickering on and off please recall this vehicle and have gm fix this problem thank you .
2005 trailblazer gas gauge fluctuates wildly. We have been trying to monitor the tank by tracking mileage. My wife used the car and inadvertently subtracted the miles incorrectly and ran out of gas in the fast lane of the 405 freeway !! A very dangerous situation. No one was hurt, just a lot of stress and a rescue mission. The gauge now stays on, or just above empty. Chevy dealer wants 800.00 for repair and says it's not their problem. My on-line research shows thousands of this car have the identical symptom. Most definitely their problem !! In addition, the speedometer has a mind of it's own. I was pulled over on the I 15 for doing 88 when my speedometer read 70. (I'm 58 and have never had a ticket) on pulling over the speedometer came to rest at 25 MPH. The officer understood and let me go with a warning to get it fixed. My problem....I need chevy to fix it !!
I have had numerous electrical problems with my 2005 chevy trailblazer (82,000 miles). I have had sensors replaced, my headlights randomly "flicker" to dim while driving at night, brake lights and front turning signals all going out at the exact same time and replacing the bulbs and/or fuses don't fix the problem, now I have two service engine lights on. Dealer says it is an electrical issue. The car is not drivable over 20 MPH, it has no power and the transmission has been affected by the computer failure. My trailblazer was driving perfectly fine, than the brake lights went out, front signals went out, service lights came on and I was unable to drive the car, all within an hour. The one module that is being replaced is 650.00 with a diagnosis fee of 200.00 to check the computer system of the transmission as 7 different codes came up on the transmission as well. So the repair fee is going to be a fortune. I find it odd that so many other people have had the same kind of issues and there has not been a recall for these electrical issues!!!
Tl*the contact owns a 2005 chevrolet trailblazer. The contact noticed the fuel gauge stopped functioning. The vehicle was taken to the dealer where a technician stated the fuel assembly inside the fuel tank needed to be replaced. There was an open investigation, the federal safety agency action number dp10001(fuel system, gasoline:delivery:fuel pump). The contact stated the speedometer also stopped functioning after the fuel gauge failed. The vehicle was taken to the dealer and the speedometer was repaired. The fuel gauge was not repaired. The approximate failure mileage was 38,000.
Instrument cluster replaced 1 1/2 years ago because of faulty instrument and speedometer readings. January of 2011 gas gauge malfunctioning reads empty when tank has been filled, and continues to misread levels at all times.
Gas gauge indicates low after fill up. It then varies between empty and full. After reading all the complaints on the internet of the identical problem with this vehicle, I feel there should be a recall. This is a serious problem. It is impossible to track how much gas you have left by mileage, especially when there are multiple users of the vehicle. If the vehicle suddenly stops in traffic (local road or highway) it could result in serious injury or death. Since this is a well known problem, I think the nhtsb should look into this and get chevrolet to recall theses vehicles to replace the sending units. I noticed a complaint was filed for the identical problem with the nhtsb back in 2010, why is it taking so long for action, with all due respect. Again, so many trailblazer owners are having this issue.
