“I have 2005 Chevrolet avalanche..I'd been smelling gas everyday I drove the truck for about a week. I left work and made it home one day and gas was leaking all over the drive way. I checked for recalls and there is a recall for the year, make and model, but the recall does not apply to my VIN according to GM. I will need to have the truck towed for repairs because it is not safe to drive to a GM dealership.”
NHTSA complaint #10550851, filed 2013-11, 160,000 miles“I have a 2005 avalanche that I was driving to work and I started to smell gas in the cab of the truck. When I arrived at work a co worker came over and stated your truck is leaking fluid. I got out of the truck and it was leaking gas all over the ground. I had just filled up the tank and it was a little over 1/4 filled. Upon further inspection after the lines dried I noticed a hole in the fuel lines. It looked like it had rubbed together with another line and causing a hole.”
NHTSA complaint #10466221, filed 2012-07, 106,808 miles“Driving home from work, I notice a raw gas smell. Pulled into my driveway, left the truck running and got out to see what was going on. Looked under the vehicle and saw gas pouring out. Stopped the engine and got under the truck for a closer look. Upon inspection, I noticed that the two plastic braid over rubber fuel lines were coiled over each other causing them to rub, wear away the plastic braid and rub the rubber hose to the point of creating a hole. This is where the gas was spraying out from, right neat to the exhaust pipe! …”
NHTSA complaint #10507194, filed 2013-04, 81,194 miles“Driving home I started to smell gas in the cab of the truck. After the truck was parked I found gas on the ground under the engine. When I had a mechanic look at the problem he found that the factory installed fuel lines were touching and had rub a hole in the fuel lines and were leaking gas on the engine also the e85 sensor module was cracked and leaking gas. No fuel line parts were available for the repair. I was told not to use the truck as the leak could cause a fire. This to me is a big problem as their is no warning.”
NHTSA complaint #10402272, filed 2011-05, 112,900 miles“Filling up with gas on my 2005 chevy avalanche. While filling with gas, with the lock on the gas despener, and watching to make sure it stops, when the gas despenser stops, about 2-3 seconds later gas starts to spray and/or leak out of the gas tank. At first I thought it was just the gas station that I used, but it has occured at mutiple gas stations. I feel this is a major safety concern that should be looked into. The dealer has said that there is nothing wrong with the vehicle, and nothing they can do.”
