The truck lost power, starred sputtering and misfiring. I shut the engine down, restarted and was able to drive it home. This same issue occurred a couple more times but each time it was restarted it drove okay. I started doing research and found a history of this same issue being reported by other owners and upon complaining to GM, nothing was done. I stopped driving the truck and it has been sitting for 3 years now. On April 22 2024 I had the truck towed to Stingray Chevrolet to have the issue checked. I was informed that the engine was would need to be replaced at a cost estimated to be 18K. I had the truck towed back to my home and it has been sitting, until I decide what I am going to do. I have continued investigating and I have found where GM acknowledged there were engine issues that dated back from 2013/2014 more than 10 years where the same problems were reported. Several law suits were found to have been filed with some wins and some losses including class action suits. I wrote GM and asked them to step up, do the right thing and replace the engine. They refused naturally so I have been waiting, contemplating my actions but the fact still remains. GM built and sold defective engines back into the early 2000's and replaced these 5.3L V8's with another engine that there are still defects being reported. I would like for GM to fully replace the engine including all components and Auxiliary devices on my truck, at no cost to me. Give it another 100K mile guarantee and compensate me for the 3 years I have not been able to use my truck.

I was told from a mechanic that the header where my spark plugs go is wrapped do to the manufacturer and is causing the spark plugs to misfire. The truck has died at a stop, is causing the truck to run horrible. I am sorry if I am not explaining it all properly. My dad bought this truck brand new in 2013 and he passed away in 2015 and I paid of the car so I could have the memory. So I have had it and been in the truck pretty much off the lot. its has only 95 thousand miles and has had this issue always, but I was always told problems with spark plugs and coils until now. please help

Truck was purchased certified pre-owned in june 2017, in june 2018 problems arose including rough idling, service engine light activation, and stabilitrak off message activation on the dash readout. General motors (gm) technical service bulletin (tsb) #10-06-01-008m was issued december, 2014 to address the repair for this problem. The issue was motor oil reaching the #1 and #7 cylinders thus fouling those two spark plugs.the truck was repaired under the extended warranty. The same symptoms appeared again in august 2020 and the chevy dealership diagnosed the same issue (mis-fire in the #7 cylinder) as described in the tsb. Since the vehicle was no longer under warranty, gm would not pay for the repair. I chose to deal with the symptoms myself which involved installing new spark plugs in the two cylinders. In mid-march of this year (2021), the symptoms appeared again and again the #1 and #7 spark plugs were fouled with motor oil. In each case, the vehicle was in motion when the symptoms presented. It's my understanding that stabilitrak is designed to help prevent accidents by giving the driver better control of the silverado. If a service stabilitrak warning appears, the silverado will no longer be assisted when a loss in lateral traction is detected. Additionally, the rough idling affects acceleration (loss of power.)

The check engine light blinks off and on,traction and stability goes off then back on ,engine runs and idles rough and sometimes shifts hard.this happens while driving and sitting still (for the lights and rough idle) not the hard shifting. While searching on internet ,found it was a common problem with the 5.3l chevy/gmc engine.
