Trailblazer EXT 4WD 6-cyl

  • Automatic transmission
  • 71,700 miles


My 2003 Chevy trailblazer has a third brake light across the top hatch.while driving down a busy highway it was flying like a wing on the back of my vehicle luckily dot falling completely off but when I stopped it came crashing down onto my window of hatch luckily not breaking all I could do is break it completely off so it would not fly into someone's windshield behind me I work with a lady with the same make and model and hers flew right off her latch causing it to smash luckily no one was behind her. I also have it in the shop due to rusty corroded hoses that went to transmission causing all fluid to drain almost burning up my transmission no indication lights ever came on other than it skipping a little luckily a service engine light came on a week later I took it to garage and just in time. Unfortunately even with power train warranty this problem is costing me $500 out of my pocket no fault of mine wheel wells and brake drums have been beaten due to lots of rust build up and doors that were recalled and fixed three times still not working right also front headlight replaced twice in two years causing me to be pulled over twice as I did not realize the problem of my lights going out frequently.

Trailblazer EXT 4WD 8-cyl

  • 40,000 miles
About two years ago while I was trying to close the glass rear hatch on my 2003 Chevrolet trailblazer it exploded in my face. I was cut on my hands, face, and got glass in my eyes. I went directly to the dealer (arrow Chevrolet, now called sunrise Chevrolet, in midlothian il.) the service dept. Looked at the damage and said they never saw anything like that, (I found out later that it is common) they sent the vehicle out to a "window repair shop" to have the glass replaced. When I got the car back, I noticed that the window was not aligned properly; the service dept. Looked at it quickly and told me that it was fine. Three weeks ago while driving down the interstate at 70 mph a loud vibration came from the glass window hatch, as I slowed down the high mount rear stop tail lamp assembly, which is a large fiberglass body piece as wide as the car and 3 feet across flew off my car striking a car in back of me. I pulled over and so did the other driver, the other driver was very shaken as so was I. slight damage to the hood and the bumper of the other car and he said that it was ok since the car was old. My car now is missing a large piece of the body and the third brake light. It was run over by a truck... the window company that replaced the rear hatch window did not affix the panel properly to the window; I have seen may complaints on other web site that the factory install and the double face tape that is used malfunctions all the time, please help me, we are dealing with two issues here, the rear window exploding and injuring me and the faulty double faced tape that is used to secure outside parts to the car. In addition, the Illinois state police stopped and told me that they could have given me a ticket for driving an unsafe vehicle but they gave me a pass and told me to write to you and send them a copy of my letter.

The contact owns a 2003 Chevrolet Trailblazer ext. The contact opened the rear hatch and heard a cracking noise coming from the top. Approximately three to four days later the contact noticed that the center high mounted stop lamp bracket failed. The vehicle was brought to the dealer simmons-rockwell Chevrolet. The dealer took the vehicle to another mechanic, and informed the contact that the failure was typical for that type of vehicle and was indeed a safety issue. The mechanic stated that the entire center high mounted stop lamp could become detached while driving and strike another vehicle. The contact found another complaint online with ODI # 10061979. The contact filed a complaint with the manufacturer, and was given case # 71-500170558. Also, the contact stated the fuel system failed. In January of 2007, the contact detected an aroma of gas while driving the vehicle. The odor became increasingly potent, and the vehicle was taken to the dealer, who stated that the fuel pump module was corroded and leaked. And the dealer quoted a repair price of $800. The fuel pump filter was repaired, and after serious negotiations, the contact was only required to pay $196. The contact searched online, and found an open investigation, PE07013 from NHTSA dated March 12, 2007 for the fuel system. The failure mileage was 42,229.
