Filed Feb 1, 2022 · Fuel system · TN · 1 injury

While driving I suddenly experienced a loss of power. Immediately the truck sputtered to a rolling stop. I was unable to use power steering or power brakes due to the loss of fuel. I later discovered that the fuel line from the tank to the fuel filter was not properly connected. Upon attempting to reconnect, it was noticed that it had broken. The male nipple which goes from the fuel tank, outward about 1 inch, had broken off and was inside of the quick release connection for said fuel line.

While driving at 65 on the freeway truck began to lose power and when I stepped on gas it didn't respond. Had to keep letting foot off and back on to get it to go. Pulled over to the shoulder turned truck off and it ran good for about 3 minutes and it repeated itself. When engine gets hot the truck loses power and you have to shut it off and repeat this step until you get to where you gotta go. No codes, no warning no nothing. Truck also shuts off while driving. Replaced fuel pump, filter, cleaned maf and throttle body replaced crank shaft sensor and it still does this.

Recently my 2002 chevrolet avalanche has begun to shut off while driving which causes the vehicle to lose power. Another important safety issue, the brakes began to press all the way to the floor while braking. On august 3, 2011 while my son was driving the vehicle approaching a stop light, he pressed the brakes which went to the floor and rear ended vehicle in front that was making a turn. The front bumper is now damaged ( t-boned) and the air bags did not deploy. I'm not very pleased that I never received any notices about the braking system. I can't afford to make monthly payments and still have to pay costly maintenance fees. I can not afford to jeopardize my life and my family, especially my granddaughter. Something has to be done about these safety issues: braking, cutting off while driving and no deployed air bags.
