The contact owns a 2001 GMC Sierra 1500. The contact stated that the fuel gauge malfunctioned and provided erroneous readings. The vehicle was taken to the dealer who diagnosed that the sending unit inside of the fuel tank was defective and needed to be replaced. The manufacturer was not made aware of the failure. The vehicle was not repaired. The failure mileage was 80,000 and the current mileage was 83,000.
Gasoline sensor or computer indicator shows low fuel and gas gauge shows no fuel when engine cold and weather is cool or cold outside, regardless of the quantity of gas in the trucks tank (full, 1/2, 3/4, etc). This just recently happened and also four to six times last winter.
Gas fuel gauge-: gauge registers empty when tank is full. Refuel light comes on & stays on. Gauge bounces back & forth & is hard to tell how much fuel is actually in the tank. Have to watch odometer to figure out when to fill tank up with gas. On -going problem!!!!!.
Gas gauge goes to empty without warning, even after filling up the tank. "low fuel" warning stays on when on empty, even when there's plenty of gas in the tank. This should not be happening, GMC should take care of there customers. This is my second GMC truck, and I bought this one because of the quality my 1st truck was good. My wife wants me to buy a Toyota next time, that's all she ever owned. GMC take care of this problem, or I'll won't be coming back for a 3rd.
First thing was that my gas gauge started to fluctuate. Up until the point that I didn't know how much fuel I had in my tank. Then my instrument cluster started to go. It started to fluctuate then dies from time to time. Rpm's , speed, gas, oil press, park, neutral, reverse, drive, 1,2,3, and miles driven cannot see anymore. Everything died the first time when I was driving home from work in the middle of the night on a dark road. Called dealer and dealer said it will cost me almost $600, which is ridiculous considering the fact that I just paid off the vehicle. I know that this is a repetitive problem with gm vehicles and am still wondering why gm won,t recognize it except only for '03 and '04 model trucks with under 70,000 miles. I bet you if people knew that one day their cluster would die under 7 years they would rather place their investment in a vehicle elsewhere. If I was stationed stateside when this problem started 2 1/2 years ago; I would have had the dealer take care of it. //signed// concerned owner.
