Seven problems related to engine exhaust system have been reported for the 2005 Chevrolet Trailblazer. The most recently reported issues are listed below.
Started smelling exhaust fumes in the cabin of the truck. Shortly after this began, the truck exhaust started getting louder. Dealer diagnosed as cracked exhaust manifold. Cost over $1,000 to repair. Dealer would not warranty.
Exhaust manifold on the 2005 Chevrolet Trailblazer ext with 4. 2 engine leaks exhaust fumes into the air and into the interior of the vehicle creating an emissions problem as well as a health hazard of driver and passengers of the vehicle breathing the fumes. Replacement parts are near to non existant since there are apparently so many of the vehicles with his problem. I have been looking for a replacement part for 3 weeks and nothing yet. Have been told by parts stores, and dealerships that they do not have them and their distribution centers do not have them either, neither do the online websites. There are no parts available in junk yards either. No options at the moment and vehicle will not pass current state inspection.
My 05 chevy Trailblazer ext lt with 4. 2 l cracked its exhaust manifold at 85,000 kms. Gm dealership in 2 different cities refused to repair under warranty. This truck was purchased as a new used demo from the original dealership with 14,000kms may 06.
Under normal driving conditions the exhaust manifold cracked with 70,000 miles on vehicle.
Just after purchasing the vehicle on December 29, 2008, I noticed the engine has accelerated and the car surges forward when stopped. If I do not keep my foot on the brake, there is a high potential of surging into the back of a vehicle in front of me. An accident has almost happened many times. I have had it looked at by the dealer I purchased the vehicle from on February 4,2009 and was told there is not a problem. It most likely will "not be a problem" until I rear end someone while stopped. This continues to happen on a regular basis, a year and a half later. I was not aware I had an opportunity to report until the Toyota recall happened. I have been living with it, anticipating the surge every time I am at a stop.
When I bought this vehicle 2 months ago, I thought the gas gauge was empty upon purchase, as it was a used car, but no it is the fuel system problem that everybody keeps mentioning. I fill the vehicle, and it only shows a half tank. Then it will go to empty with the warning light coming on. As someone who travels a lot, and for long distances, this is a horrible defect. The exhaust manifold has become loud, which means another expense on a 2005 which shouldn't be happening.
