Over the past few years squirrels have eaten through the fuel line of the truck just above the fuel tank multiple times. As soon as the ignition switch is turned on fuel gets pumped out very near the exhaust system. The driver may not notice anything wrong immediately causing a very real fire risk. Today is the fourth time I have experienced this issue with this truck.
The fuel pump rusted out from the gas tank causing fuel to leak onto the hot exhaust system. There was a stong gasoline odor which kead to the discovery. The repair bill was $911. 00.
This vehicle was sold by a dealership with these issues the frame has a half inch wide six inch long gap needs a fuel pump control module and the engine needs lifters replaced.
I may have a illegal auxiliary emission control devise result in excess emissions of nitrogen oxides that are similar to those made against Volkswagen and 2011 GMC sierra duramax diesel truck. General motors may have intentionally installed an electrical �cheat devices � producing passing emission results.
The throttle body and pedal chip went bad causing a rough running engine, loss of power, check engine light, and loss of traction control. Mechanic stated he's been replacing 5-12 a month on the same engine (5. 3 liter v8). Other models are supposedly under recall. Repairs cost in excess of $500.
Pulling out of a snow covered parking lot the engine light came on dic then the message, reduced engine power, the engine began to run very rough at a lower idle speed, as began to happen the truck lurched forward and I had to press hard on the brakes very hard like I was fighting the engine speed to slow, then the message changed to service traction control, I had no control over the gas pedal and could only move at about 5mph, then the message changed to service stabilitrak, I got to another area of the parking lot, parked and shut off the engine for a few minutes and the issue would not go away. I was more than two hours from my home. I removed the red battery cable then replaced it and was able to start the engine and it operated normally for a while. One and a half hours later while driving 60mph it happened again and I costed off the interstate and could not get it running again. Had to be towed to a dealership. They said there was a service bulletin to replace the throttle body but want to charge me $215 to clean the other fuel related parts. This needs to be a recall. If it was a recall I would not have to pay $215 to complete the work properly.
Went about a mile was getting ready to make a left across MD rt 4 when I lost power and reduced engine power light came, had a close call, on did some research and found a technical notice about throttle body and injector sensors they need a recall.
Noticed one morning when starting up my truck the valves were tapping. Like out of adjustment. My 5. 3 is roller lifters so I was surprised. Took it to dealer and was told that gm had a recall on Cadillac, chev and GMC 5. 3 and 6. 2 engines with defective lifters. Dealer replaced the lifters. Took a week. When I picked up truck service adviser told me to expect to come back around 60k for a new camshaft. Now what!.

For the air bag, the light continually goes on and when I took it to dealer; they said it was fine, but when I took it later; dealer said that warranty had expired and it would cost me $800. I just left it alone. Light continually goes on and turns itself off. For the seat belt, back seat middle, the dealer repaired it twice, but once warranty expired than they wouldn't fix it anymore unless I paid. For the gas, I pump gas and it constant causes pump to pop and shut off. They had fixed the problem at dealer, but once warranty expired they stopped. I had to pay for all repairs.
