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 NHTSA 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,

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 NHTSA 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.

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.

- Burnsville, MN, USA

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 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 with a diagnosis fee of $200 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!!!

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.

March 30, 2011, I spent $80 on fuel to fill my Trailblazer with gas. I started driving and the gas gauge never moved, and was still showing empty with the low fuel warning chiming. When I was almost home the fuel gauge finally started moving but never went past a half tank. I inspected the vehicle to see if there were any signs of a fuel leak and nothing looked out of the ordinary. When I had to leave again to run errands the fuel gauge would move, however, it would go back down to empty when I was stopped or put the car in park. I have also had issues with rear tail light panel wires frying and having to replace those when there were no apparent causes (moisture, etc.). lights dimming while I roll up a window or push other buttons in the car (radio, climate control) and lights in certain areas of the car just blowing out. Fuses are fine, alternator and battery are fine. Why is this vehicle having so many problems at 56,000 miles? I understand that these are not life threatening issues, but what is next. Why do I have to constantly monitor my mileage just to make sure I don't stall or run out of gas when I am driving. Are we the customers supposed to shell out $$$ to have repairs done continually on defective equipment and components. I don't think so. GMC needs to drastically improve the quality and durability of their products, and step up to the plate and take care of the customers they do have. Word of mouth is way more effective than millions of dollars in advertising.

Speedometer cluster malfunctioning. After seeing that this is a very common issue with these models and others that did have a recall I felt it was my duty to file this complaint. The speedometer reads 70 when I am stopped and well over 120 when I' doing 30 as per my gps

The front blower stopped working while my wife was coming home from a trip with my kids.the temperature outside was 28 degrees the windows fogged up and she hit a deer that she would have seen if the windows weren't fogged.I have replced the blower resistor switch which had a burnt connector it lasted 3 weeks and has gone out again. This is a very bad problem because even when you have this problem repaired it still malfunctions without warning. This is putting myfamily at great risk. Onthe other hand had I known that there was problems with Chevy trailbrazers and defective parts I would have brought a Toyota.

The cluster/instrument panel on many 2005 Chevrolet Trailblazer does not work, the gas gauge does not work, along with the speedometer, and the battery meter. The failure of these functions can cause speeding/ driving to slow, which could intern cause an accident. The gas gauge always shows that the tank is empty even after a fill up, which could cause you to run out of gas, and get into an accident. The only way to solve the problem is to replace the cluster panel.

The contact owns a 2005 Chevrolet Trailblazer. The contact stated that one year ago the speedometer failed which made it impossible for her to determine the speed she was driving. The fuel gauge was also displaying the incorrect reading, and the fuel light remained illuminated. The vehicle was taken to a local mechanic who performed a diagnostic test for the fuel failure which indicated that the fuel sending sensor was defective. The local mechanic did not perform a diagnostic test for the speedometer. The vehicle was not repaired. The manufacturer filed report 71-930473192. The failure mileage was 10,000 and the current mileage was 110,000.

- Kings Park , NY, USA

The contact owns a 2005 Chevrolet Trailblazer. The contact stated that the speedometer malfunctioned. The vehicle was taken to a local mechanic who performed a diagnostic test and informed her that there were no error codes or warning lights illuminated; therefore, they were unable to repair the vehicle. The contact notified the dealer in regards to the failure and stated that there were problems with the chips in the computer and they needed to be replaced. The dealer wants the contact to pay for an additional diagnostics test although the local mechanic completed one. The manufacturer was not contacted. The failure mileage was 81,000.

2005 Chevy Trailblazer lt speedometer failed.

- Barnhart, MO, USA

Traffic was horrible bumper to bumper, I was driving and realized not to rush so I stood in the first lane, as I was driving bumper to bumper I always drive within one car lengths in case I get rear ended. As I am driving bumper to bumper all for a sudden next thing you know my car just suddenly accelerated at incredible speed I manage to swerve into the emergency lane to avoid causing a multiple car pileup my car died instantly I started it up again and it just wanted to take off as it did before I turned the car off thinking to myself my god what just happened and what is going on, I am trying to calm my 12 year old child because it was the most frightening thing I am my family ever went thru. I press the break and just relax for a second and started the car up and it was fine. However, my nerves were pretty much shaken, I had taken the car to jj auto shop in hayward who is ase certified he did a diagnostic on the vehicle he said he could not verify what I was saying, no error lights and the history was clean. He also mentioned the computer at times does not pick up a split of a second acceleration. He believes my story and said everything is done thru computer so there is no finding as of the moment. I was not sold on that but he also recommend I could change the body throttle @ $700 but he said I just dont want you to buy the part so you could just drive in the slow lane and if it happens again to shift the car into neutral and turn it off asap> my thing is since cars are computerize this should have why is it they could not verify my situation and also body throttle what he was looking at and what Chevy thinks it was! so my complaint is for Chevy did they overwrite software to overlook sudden acceleration? the only major issue I had had with my vehicle was when the speedometer went crazy as I was driving 110 but was really going 35mph
