I filled my tank at a gas station and when leaving the "check engine" light came on and the fuel gauge dropped down to "e" and low fuel light came on. After 10-15 seconds the fuel gauge went all the way to "full". A few minutes later it did the same thing again, and has continued.

The fuel sensor on my vehicle swings wildly from empty to full even when the fuel tank has just been filled. This results in the check engine light to constantly be on. I am unable to determine how much gas is in the car due to the faulty sensor. I have checked the internet and this appears to be a widespread problem that has been reported for years. I called gm and they told me that they have known about the problem and will cover 50% of the cost only if I take it to a gm dealer and that my portion of the cost would be between $500 - $600 dollars. They would not cover any of the cost if I take it to my local mechanic. This problem has been known by gm for years and they should have issued a complete recall to repair the defective part(s).

Fuel sensor, located in gas tank, has failed. No matter how much gas is in the tank, be it full, half full, or less, the sensor bell rings and the gauge registers empty. This also causes the check engine light to come on. Gmc should recall, as this is very dangerous. I thought I had more fuel but ran out of gas on a major road, thankfully no accident. Gmc has admitted there is a problem and has agreed to pay 50% of repairs, but this is only done under a vehicle warranty extension, not recall.

Problem with severe fluctuations of fuel gauge. Research shows your ongoing investigation # is dp10001. Upon filling tank to aprox. Tank the gauge suddenly started going wild and within 1 mile of driving the "check engine light" appeared. After investigating numerous on-line resources it is clear that this problem is not only limited to this vehicle but is a serious problem in the gm lineup. Dealership repair costs are estimated in the $800.00 to $1000.00 range. This is unacceptable for a problem that gm knows to exist yet refuses to take any unilateral action on.

Gas gauge reads empty at most times, never gives accurate measure of tank fill. Also check engine light turns on sporadically, although diagnosis by engine tech confirms no bad codes are causing this warning light to glow. Research on the internet and talking with dealerships and mechanics have confirmed that this is a very common defective part problem that gm has not issued a recall on. Hundreds, probably thousands of frustrated drivers. It effects gmc envoys, chevy trailblazers, and other gm makes in 2004 - 2006. Thank goodness taxpayer dollars are keeping them afloat! God forbid they actually support their products and maintain customer loyalty and integrity!
