Trailblazer EXT 4WD 6-cyl

I was driving down the road about 20 mph and the drivers window went down by itself and wouldn't go back up, sometimes when you try to start vehicle nothing happens and then a few seconds later it starts on its own, when it rains all the speakers quit working except the front tweeter speakers, sometimes when I shut the drivers door kind of hard it wont start and U cant lock doors with keyless entry, fuel gauge quit working after I filled up with gas.

  • 71,000 miles
Fuel gauge showed I was empty after filling up the car. The gauge now reads erratically and does not show the proper amount of fuel in the tank. My wife is the primary driver of this car and I fear that she will run out of gas due to the "failure" of the gauge. We are doing our best to drive by mileage but our mpg varies quite a bit depending on our driving situation. Just received a letter from GM advising they will pay 50% of repair costs. However, I feel that this safety related item failure should be covered entirely by GM via a recall. Anything you can do to help would be appreciated.

The gas gauge on the dashboard does not work. It always says the tank is empty, even after filling it.

Trailblazer EXT

  • 49,000 miles
The contact owns a 2006 Chevrolet Trailblazer ext. Ever since April of 2009, the low fuel indicator light illuminates on the instrument panel even when the tank is filled with gasoline.

The contact feels that the failure was due to a manufacturer defect. The failure mileage was 49,000.
