Our vehicle died at a turn signal light in a dangerous intersection. No warning from the vehicle as it was running normal. It would turn over but no start. Police force a tow out of the busy intersection right away. It starts up at the mechanics. They tested fuel filter and other stuff. We get on the highway in traffic and get 6 miles out and no warning we die and had to push the car to the shoulder on in dangerous conditions. Sit for 2 hours and it fires up. So we found shade and waited for cool down. 2 hours away from home and it took us 9 hours to get home. We drove it to the store and when we were done shopping it fired up. Went around the corner to other store and shopped 2 hours and came out and it would turn and no start. Tried starting every 30 minutes to hour from 9:30pm to 1:40am and then it fired right up then drove 30 minutes to home. After researching and finding quite a few with same year make and model having the same issue we found that it is the pwr/trn relay plug in area in the fuse relay center. When we broke the plastic off the relay and wrapped a rubber band around it so it's constant contact and plug it in, it will fire up every time. I can drive it all day like that with no issues. I have to turn the key from running to accessory mode then remove the rubber band and then power off the car. Don't want to fry com. The relays are good and problem is the fuse relay center. Chevrolet said themselves that this model is notorious for fuse relay center problems and usually require replacement. It's a known defect. There are two pictures attached from one of the other people with same vehicle same problem and in order to make his fuse relay center work properly he had to wire/reroute his pwr/trn relay as seen in the picture. This needs to be investigated as this is a well known issue with Chevrolet and the Trailblazer.

The check engine light comes on&off a lot right after fueling, I took it to the GMC dealership&had the camshaft replaced because it kept cutting off every time I turned a curve.I tried to show or tell them about this GMC recall letter I got on my 2005 Chevrolet Trailblazer, but they said that it didn't apply because of the mileage&I told them the car is not 10yrs old& the paper is saying 10yrs/120,00 miles& for me to take it to the dealership so that the manger can send my bill & receipt in for reimbursement they wouldn't do it.I guess because I'm a woman.driving to work on the interstate the car shut completely off. The car was still moving when all of a sudden all the lights and gauge's lit up and the car cut off. It did not lock up so I was able to steer it from the middle lane of a three lane interstate highway to the grass on the side without getting killed or hurting someone else.I had just filled it up with gas with a quarter of a tank from the full line. Once I got the car to a complete stop and thanking god that this was not tragic, I put the car in park and waited a few minutes before starting it back up. It started back up as if nothing had happened. I took it to auto zone to get a free diagnostic check&it showed that nothing was wrong. A few weeks later after I would cut the car off the air conditioning would not stop&the engine light constantly comes on every other time I hit the brakes. I had to keep taking out fuse #35 to get it to stop even after the car was cut off just so the battery won't run down. Took it to the dealership and was charged an arm&leg to get it fixed. I showed them the recall letter again and they said it was too late for them or myself to do anything about it. I have all of my receipts & the letter from GMC about the recalls.im sure my vehicle fits in there somewhere with these problems& truly would like 4 them 2 give my free car.

In 2007 I paid off my vehicle and now became the proud owner of my truck. In 2009, I noticed some problems with my truck. First, the gas gauge would say "F" full, but really it was on "E" empty. Then the mileage gauge " I can be on the expressway going as fast as the other cars, but my car reads 20 mph. This is crazy!!!! I called at 800-number for GMC and was informed that there was no recalls or any others calls for the 2005 Trailblazer, which I knew was a huge lie!!!! I decided to go on line and google the make and model of my car. Wow? guesses what I seen" there were over 41,000 people who have the same problems that I had for their 2005 Trailblazer. Again, the problem with my truck has gotten worst. In 2010, I called again and was informed that their still wasn't any other calls or concerns with my truck and that I should take it to an authorize Chevy dealership. Well, I did... in 2011, I called again.. same script same story!!! I received a letter for a emission test for my car. Well, let me tell you when I took my vehicle up to the emission testing it failed!!!. I got an estimate cost of $ 1900, plus they found 3 additional codes.. well, I got a 2008 Chevy Impala. I went from paying no car note, to $381 a month note. The week of September 4th, 2011.. I receive a letter from Chevrolet addressing the issues with the 2005 Chevy Trailblazers, and offering 50% on repairs for the same problems that I have been calling on for 2 years.

Gas gauge malfunctioning, engine light keeps coming on and off. In looking at different web-sites, this is common for this vehicle. I purchased the vehicle on 06/20/2010 and have had several things go wrong in the (8) months that I have owned it.

My 2005 Chevy Trailblazer's gauges/panel is not working at all. It reads that the truck is running hot, that I'm going way over the speed limit (when the truck is actually parked), and that I have no gas (after I fill it up). My oil gauge it also out of whack. Please help.
