“2007 Gmc crewcab Sierra with 5.3 liter ,auto, has had three plastic fuel line failures in last two years. After detecting a fuel odor, gas was found to be dripping/sprayed in the area of the exhaust pipe. Appears to be a fire risk. Same truck was delivered with warped flex plate, and has experienced major and repeated A/C failures. This truck is driven by a 50's female, has never towed, been off road etc. It is at a repair shop but has about 35000 miles on it.”
NHTSA complaint #10535356, filed 2013-08, 30,000 miles“5.3 vortec with afm is now burning oil at the rate of 1 qt every 800-1200 miles. The more highway driving the more oil it burns. Gm is very aware of the issue and just refuses to make the proper repairs volunteerly, but is more than happy to put the customer through all kinds of bs. Will start the oil consumption test, tomorrow. If that fails the dealer told me they will try the oil shield fix and if that fails, they will replace pistons and rings. Seems like a huge waste of time when they know there is a major problem.”
