GMC Sierra owners have reported 22 problems related to other fuel system fuel gauge (under the other fuel system category).
Gm mailed a notice that the instrument panel in 2004 sieera trucks is subject to failure including fuel gauge, speedometer, etc. These can be very serious safety concerns depending on driving conditions. Gm has offer to extend the warranty to 70,000 miles or 7 years. This totally unacceptable from a safety standpoint.

Fuel gauge has been malfunctioning for several months now - sometimes works properly, but other times reads empty when tank is full, reads more fuel than in tank, etc. I have several friends who have this generation of gm full-size truck (GMC Sierra, chevy silverado, GMC yukon, chevy tahoe - gmt800 series), and most of them have the same problem. I am told that the issue is with the fuel sending unit.

: the contact stated while driving any speed, the gas gauge goes up and down, and the fuel light flashes. The dealership determined the fuel sending unit needs to be replaced.
My gas gauge dances constantly or just stays on empty with gas gauge always on GMC Sierra 2001. Sometimes it shows the gas level correctly for about 30 minutes after getting gas then it moves around or goes to empty even though it is not empty.
Incorrect fuel gauge readings when at a full tank.

The contact stated that the fuel gauge indicator iwasnot working correctly. When the fuel tank was filled up the gauge will move to empty, and the low fuel light will come on. After driving the vehicle for a while the gauge will move to full. But with continued driving the gauge will drop down to empty, and the fuel light will come on again. The service dealer stated that the sensor needed to be replaced. The contact had not replaced the sensor.

the consumer owns a 2003 GMC Sierra. The consumer stated he has been having problems with the fuel gauge, fuel pump, and fuel filter. The fuel gauge does not work, he has to constantly fill up his truck to make sure he has enough gas. It started at 38000 miles just out of warranty when it stopped working. He had the part estimated by a mechanic and it is going to cost around 700 dollars just for the part. He does know of other people with the same truck and the same type of problem. The fuel gauge reads completely wrong when he is on 3 quarters of a tank it will be empty.

Vehicle stopped running while driving 20 mph, with a quarter of tank of fuel registered on the fuel gauge. Dealer was notified, and dealer informed consumerthat the vehicle was not covered under a recall.
The fuel level gauge in my 2000 GMC Sierra has been erratic and is now consistently reporting the tank is empty every time I fill it up and it will then keep flipping between full and empty for about the first 100 miles after fill up. I cannot trust the gauge any longer to tell me when the tank is getting low either, as it will show 1/8 to 1/4 even when it will take 26 or so gallons of gas. This seems to be a faulty level sensor that is affected when the tank is full, mostly, and I am concerned that the electrical system connecting to the sensor in the tank may be shorting out in the tank near or in the presence of gasoline! I understand this is a common problem with these vehicles and suggest that it should be recalled and fixed by the manufacturer.
The fuel gauge located on the dashboard malfunctioned. The lever fluctuateed between full and empty. The accurate amount of fuel in the tank was unknown. To correct this failure the fuel level sensor has to be replaced. This is a common failure with these vehicles.
While on a trip gas gauge malfunctioned. The fuel gauge remained on 3/4 while the mileage was 335. When filling the tank it showed full after 4 gallons were delivered. The problem continued thereafter till present. The only way to know the fuel level is by the tripometer and guess work.
Dear sirs, in January of 2000 I purchased a new GMC Sierra pick-up truck from a general motors dealership. In April of 2003 the gas gauge began to act erratically for a few seconds after a fill-up. It would go from full to empty, and then act normal until the next fill-up. The odometer reading was approximately 48,000 miles when this problem first occurred. In September 2003 the gauge would only register full. At this time I had the truck inspected by two independent garages. They stated that they had seen a number of GMC's with the same problem. It seemed that the 1999-2001 models had a defective part. When I took the truck to the dealership in September 2003 I was told that the fuel tank would have to be removed in order to replace the part. I was then told that the cost of this repair would be $650. 00, including parts (the part cost was $395. 83). I was informed that because the mileage on the truck was approximately 64,000 miles, the warranty did not cover the cost of this repair. I stated that the mileage should not be a factor for a fuel gauge. I did not expect gm to take full responsibility; however, I feel that some consideration should be given toward the cost of this part. I have contacted the gm consumer department however no relief has been offered toward this repair/part. I do not feel that I should be held fully responsible for a defective part.
Fuel gauge fails to operate after the vehicle has been running for approximately 20 minutes.
See all problems of the 1998 GMC Sierra.
No event leading up to failure. The fuel gauge quits reading full instead reads completely empty giving no indication of fuel level nothing has been currently done to fix the problem as it involves removal of pickup bed to replace sensor in fuel pump. 5 other vehicles in same area have same problem.
