Sudden Low Beam Headlight Failure
The 1st generation TrailBlazer's low beam headlights can suddenly shut off even though the lights themselves are perfectly fine. The issue is a a defective headlamp driver module which is responsible for distributing power to the lights.
One of Chevrolet’s solutions for stopping thieves from driving away with a car is, coincidently, doing the same thing to the actual owner.
Inaccurate Gas Gauge
One of the more infamously problems with GM vehicles is a faulty fuel gauge that often leaves owners wondering just how much gas is left in their tank.

1st Generation Trailblazer Key Numbers
I was driving home from a wedding on the interstate at 55 mph, and my headlamps failed. Everything went completely dark. After a panic, I was able to turn on my high beams, and they worked properly. I turned the car off, waited a few minutes, and turned it back on. The low beam headlamps worked then. Since the first incident, I have had approximately 10-15 other incidents of the same occurrence.
I was positive that my vehicle was included in the recent recall, but when I called my local dealer, I was advised that my vin number was not included. I don't understand, since the issue on the recall is exactly the issue that I am dealing with. I have had to limit my use of the vehicle at night for fear that the headlamps will fail. Side note - they have failed at night twice in the last week alone.
