Here is my story, 2013 gmc sierra SLT crew cab 5.3 purchased in 2016 with 60k miles . One month after purchase check engine light came on, cylinder #1 misfire...didnt think anything of it but replaced spark plug which temporarily fixed the issue, one month later #1 misfire again...took the truck to dealer and they acted like they knew what the problem was, did an oil consumption test and found it was using 1qt in 2000 miles. Engine rebuild under warranty , I also purchased an additional warranty which stipulated they change the oil of which I demanded the oil be changed every 3k miles which they agreed to ...35k miles later cylinder 1 misfire, now the fun begins because the additional warranty should have kicked in and paid for the rebuild...NOT, the company refused to pay because they said I shouldnt have been sold the warranty in the first place! During all of this the dealer changed hands with a new owner, I ended up saying screw it and took a big loss selling the truck back to the new owner and buying a toyota instead . the tech who worked on my truck let it out that this issue repeats itself, my truck already had the "fixed" valve covers which obviously didnt fix the issue...had I known about disabling the fuel management I would have done it day one....i even considered getting a bigger crate engine and dropping it in the truck after going through this nightmare I find out a coworker was going through this scenerio with a 2014 silverado 5.3, they sold it and bought a 2015(btw the dealer sold that truck with the issue 3 days later)... guess what, same damn issue! dealer bought that truck back and talked them into a 2018 on lease, so far the 2018 hasnt popped this issue up but they have decided to return the 2018 when the lease is up
