The fuel level sensor in the fuel tank may fail causing erratic fuel gauge operation. Our technicians tell us that on high mileage vehicles you may wish to replace the complete fuel pump module assembly if this condition occurs.

On certain 2005 - 2007 vehicles, General Motors has provided a special service policy covering the fuel level sensor, agreeing to pay 50% of the repair cost. This coverage extends for 10 years or 120,000 miles from the original "in service" date of the vehicle. Please contact your local GM dealer for more information.

    Eratic fuel gauge after filling up. Low fuel light and alarm sound but gauge sometimes goes back to full. How hard is it to change this sensor and how much should I expect it to cost if I take it somewhere to have it done?

    After filling up, the gage will read empty, but will eventaully read correctly. I'm resetting my trip odometer each time I fill up just in case though!

    We had this fuel sensor problem only about a year after we got this car. At first Gm sent out notification about the problem and offered to fix it for 50% of the cost. So we just kept track of milage when we filled up. Then at about 94000 miles They sent out a notice again in July 2013 that they would cover the whole cost up to 120000 miles, so we went and had it fixed no problem. If any of you paid the 50% to have this done they have a form you can fill out so you can get reimbursed.Ask your dealer.
    Now if they would just do something about the stinking air suspension that keeps leaking ! No more GM for me after this one. Anybody want to buy a lowrider?

    Fuel sensor slowly failed - now permanently on empty. 80,000 is approximate - I have been living with this issue for over a year since I cannot pay to get it fixed.

    Fuel gauge shows empty when full, and bounces around up and down after that.

    Fuel level sensor has long periods of time that fail to correctly display the correct level of fuel in the Terraza gas tank. Today was a first in that the faulty sensor caused the check engine light to come on. The P043 P code indicated that the fuel level sensor has a circuit high input. Now, it can't pass a smog test and I must have the problem corrected instead of just living it as a known problem. This problem started early for this vehicle, for the past 5 years now.

    Fuel guage shows empty after filling, sometimes bounces up and down, now it shows empty all the time.

    the problem starts when the weather is hot, I think. It is chronic, the engine light comes on and the fuel gauge drops to empty. Not repaired yet.
