Trailblazer 4WD 6-cyl

  • 75,000 miles
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.

Trailblazer 4WD 6-cyl

The speedometer begins to tick as I press on the gas pedal and jumps anywhere to 80-100mph and I may be only going 30. It stalls and then continues to jump until it is reading off the scale. It now resides off the scale and I have no way of telling what speed I am traveling at other than using my gps. The safety concerns of not knowing the speed at which I am traveling along with the legal issues I may face is why I am filing this complaint.

The speedometer at any givin moment will go haywire. Will read over or under what speed you are actually driving. This is caused by a faulty instrument cluster. Safety concern is that you do not notice right away that the speedometer is out of whack so you don't know how fast you are actually going, leaving you vulnerable to driving too fast for road conditions and potentially causing a very serious accident. This is a known problem in the 2005 Chevy Trailblazer and GM will do nothing to repair this.

About 2 weeks ago the speedometer in my 2005 Chevy Trailblazer stopped working properly. The only thing out of the ordinary was the nearly 16 inches of snow that we got in the chicagoland area. At first it would not move, then it read that I was going 30 mph while the car was in park. Now it is stuck past 120 mph. I am unemployed, still trying to make car payments on this car and do not have the $500 + that Chevy has told me they would charge me to fix this problem that I am sure they are well aware of with this make, model and year SUV.

Trailblazer 4WD 6-cyl

  • 53,500 miles
Speedometer stopped working yesterday as wife drove home. 2005 Chevrolet Trailblazer SUV only has a bit over 53,000 miles. Can't tell how fast or slow we're going now. Seems like a defect that should not occur to vehicles at this age/mileage, let alone any age. Typical GM "quality" I guess. This defect has the ability to affect driver safety and is obviously not rare judging by others who've written on the internet about it, I believe a recall is in order. Have not taken for repair yet, but was told GM will not cover the cost and that it will cost around $500 to fix.

Speedometer on the 2005 Trailblazer. It went crazy on me at about 60,000 miles and after taking it to the dealership, they informed me there was a recall on the Chevrolet trucks with that problem, but not the SUV's, even though the equipment was the same. The cost to me is $500+ which as a retired person on low income I cannot afford. I have received 2 tickets for going over the speed limit....even though I am extremely careful and try to drive with the flow of traffic. I am furious....Chevrolet should recall this and pay to have the problem fixed...it is a defect as I have seen numerous complaints about this with the Chevrolet Trailblazer.

Trailblazer 4WD 6-cyl Diesel

  • 65,000 miles
Speedometer jumped one day from 65 to 160. Almost is constantly pointing near the odometer. Speedometer pin still moves but is completely inaccurate. Dealer wants over $500 to fix it. It happened in a friends 2005 Chevy Silverado duramax diesel 3500 and it was a recall and was fixed. It also happened in a friends 2005 Chevy Impala and was not fixed. It is clearly and issue in all the 2005 models not just the Trailblazers.

Trailblazer

The contact owns a 2005 Chevrolet Trailblazer. While driving approximately 60 mph the speedometer displayed 90 mph as the vehicle mileage increased to 100,000 miles. The vehicle was not taken to the dealer for the failure. Approximately a year ago the oil pressure gauge malfunctioned and the vehicle was taken to the dealer for diagnostic testing. The vehicle was not repaired. The failure mileage was 100,000 and the current mileage was 102,000.

Driving down the road at 50 mph and then you slow down. The speedometer stays at 50 mph then when you speed up it goes up accordingly. When you stop the car completely the speedometer says you are still going 30 mph. Then you have to shut the vehicle off and start it to try and reset it. Doing this only takes 8 mph off so it takes a while. It seems to do it more in the cold weather than in warm weather. I think this is a major safety issue, due to the fact that you have no idea how fast/ slow you are truly going. And when the speedometer does decline with your speed it is very jerky and sticks.

My 2005 Chevy Trailblazer speedometer stopped working. This started as an intermittent problem and has progressively gotten worse. There seems to be no correlation between outside temps and when it works. When it does work it displays inaccurate speeds. This seems to be a consistent problem in 2005 Trailblazers based a an internet search for the same problem.

  • 98,000 miles
The contact owns a 2005 Chevrolet Trailblazer. While driving approximately 5 mph, the contact noticed that the speedometer did not indicate the correct speed. Other components on the instrument cluster were also not functioning properly. The vehicle was taken to an authorized dealer who stated that the instrument cluster needed to be replaced. The vehicle was repaired but the problem occurred again. The failure mileage was approximately 98,000 and the current mileage was approximately 114,000.

Trailblazer 4WD 6-cyl

  • 84,000 miles
2005 Chevrolet Trailblazer...a couple of days ago, while my 15 year old daughter was driving this truck the speedometer got stuck on 10mph and she could not tell how fast she was really driving. We were on a back country road (thank god) not in heavy traffic but I know she had to be going at least 45mph. She has just gotten her learner's permit a few weeks earlier and did not have much experience driving so this really freaked her out. Now the speedometer will work when you first start the truck but if you come to a stop it will stick again and at times it will read higher than what I am actually traveling. Like this morning, upon starting the truck before it was ever put into drive the speedometer read 10mph. This could be a very hazardous defect and GM should recall this problem and fix it. In researching, I see that there have been many complaints about the speedometers in these trucks, yet GM has done nothing to resolve the problem. It is costing consumers approx. $500-$750 to repair. I have gotten an estimate of $600 myself but have not had the repairs completed yet. No money to do so and hoping my warranty will cover it.

  • 58,645 miles
2005 Chevy Trailblazer...power to instrument panel including radio cuts in and out leaving a variety of warning lights lit and low fuel warning audio signal going off. Resets when ignition is turned off, but happens again when car is started and happens in irregular intervals for the entire time the car is running. The door locks (including hatchback) do not always unlock when car is stopped, and interior lights and radio sometimes stay on. All gauges (gas, oil, temperature, etc) go to zero. After talking to a mechanic friend, we took the dashboard apart, pulled out the cluster and put it back in. That appears to have stopped the problem for now, but we have not used the vehicle much since doing the repair. We have been told it could require a new cluster costing in the $400 range not including labor. It is interesting that 2003-04 vehicles with this problem were covered by a special policy, but not the 2005.

Trailblazer

  • 96,000 miles
I have a 2005 Chevy Blazer that we took on a trip to nashville. On the interstate we realized that our speedometer kept going up and everyone was passing us. By the time we made it to an exit the speedometer had made it all the way around to D (drive) at the bottom of dash. When we stopped it would only go back to 50. When we stopped at autozone the guy told us he has seen this in 2 of the Trailblazers that is family owns. We were going to have it checked but the next day the speedometer decided to somewhat work, now it is about 5 miles off. I have been told that it probably will happen again.
