Fuel gauge drops to empty constantly, even where there is half a tank. Only 5-10% of the time it shows how much fuel there really is. This happens while traveling and while stopped.

The gas gauge shows empty even after the tank is filled. Other 2005 trailblazer models have had a recall on this issue regarding the gas gauge and sensor but my model did not. It also causes the check engine light to come on after putting fuel in the gas tank. The gas gauge shows empty at all times ( when your moving, and stationary). Not accurately knowing how much gas is the vehicle can cause you to stall out while on city streets or on the highway driving 60 MPH.

The vehicle has an idle issue and cuts off once you turn the AC on. I have spent a lot of money over time and I read I'm not the only one with that issue.

I have a 2005 tb ls, and it's a pos. As soon as I drove off the lot I've had nothing but issues. My brakes pulsate, go to the floor, get stiff as a board, basically they don't work. I have to pump the brakes quickly in an effort to avoid a crash. I filled the gas tank to full, huge mistake. The moment I did that the check engine light has flashed and sporadic idling. It has a loud whine under the hood, front turn signals and hazard flasher randomly stopped working. Car will die if I run the A/C for more then 15 mins. It will pull to either side when I apply my brakes. I have always kept up with proper maintenance, tune up, etc. This is absolutely terrible, that so many have the same [xxx] issues and yet chevy will not recognize/take responsibility for their obvious flaws and lack of mechanical knowledge..I just want out of this [xxx] lease and a replacement car!!!
