Chevrolet Avalanche 1500 loss of power problems

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.

Car stalled unexpectedly on freeway exit for no apparent reason with loss of power steering and all functions. Had to coast to a stop and luckily no other cars were behind us. *tr additionally, car fuel tank valve does not stop gas when fueling and causes gas to surge out of tank when fueled and onto vehicle. Reported this problem to dodge and they said this VIN no. Wasn't covered by recall.

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.

Since purchasing this truck on 02/01/2007, there have been multiple problems with the transmission, engine, and electrical system that have not gotten resolved, however they do seem to get worse. The worst of these problems has occurred while driving on the northeast extension of the pennsylvania turnpike. While attempting to pass another vehicle in the left lane the engine "shut off". I was doing approx. 60-65 MPH when this occurred during the am rush hour. After losing engine power I somehow made it safely to the right hand shoulder and let the truck "coast" to a stop. The power steering was not working, nor were the power brakes. After finally stopping, the truck did restart and I slowly continued on my way to work. The truck was taken to a dealership, and for almost (2) weeks the truck sat there while they tried to figure this out. After getting the truck back, the same problem occurred, and it went back to the same dealership. Since then it has been ok, except I have lost dashboard lights, radio lights, and also the cruise control indicator light, they claim other problems, however these issues were never a problem before they worked on the truck. Now I have air-bag lights flash at me while driving, and the transmission is slipping, this was the first problem with the truck that I reported on 03/14/2007 to the dealership that I purchased this truck from. I have already paid over $1500.00 I repair costs, only to have them tell me it will cost approx. Another $800.00-$1000.00 to correct the air-bag, and transmission issues. These should be covered by my warranty, except the dealership insists I pay for the repairs. I have paid enough, and I am at my wit's end with this truck, and the dealership. I feel that I can no longer "safely" drive my family around in this truck, and I still have many years of payments left. ( I have never been late on a payment) please help me, I feel as though I have been sold a "money pit".
