Fuel gauge intermittently reports empty when vehicle was just fully filled with fuel

Filed Dec 12, 2020 · Electrical · 80,000 miles · CA

I own a 2005 chevrolet trailblazer (bought new) with approximately 79,000 miles. The fuel gauge light is illuminated indicating I am low on fuel however my gas tank is full. I noticed the problem after filling my tank (no light on at the time). After filling the tank, the fuel light came on and the gas gauge bounced back and forth from quarter tank to half tank and now the light stays on with gauge showing empty. I would appreciate any help you can give or recommend any possible action to take.

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 fuel level sensor is a very common problem. The tank is filled full but it will always read empty. I already have a refurbished cluster so it will not be the cluster's fault. Gm needs to recall the fuel level sensor to be fixed to avoid accidents on the road.

Gauges on the instrument panel stopped working. There are currently 3 gauges not working on my instrument panel including the speedometer and the gas gauge. This is extremely dangerous not knowing when your gas tank is empty or how fast your going. The gauges do not work whether I am driving or stopped.
