Greetings all, new to the forum.
Picked up our new Denali here in Toronto a month ago and love it so far but...
I cant help but get a pit in my gut thinking about the valve lifter issue that seems to be prevalent in the 5.3 and 6.2 engines. I know GM is producing 10's of thousands of these trucks each year and many seem not to have issues with the engine but is it a matter of time? There seems to be no manufacturing time frame of this issue that I can see. Apparently they came up with a fix for the broken valve springs some time ago. so that a positive.
From what I gather the issue stems from the Dynamic Fuel Management system and I tried looking for a DFM disabler but there seems to be nothing on the market for the SUV's only pickups.
Its a mixed bag of feelings with this new rig, I love everything about it including the 6.2 engine but there is always the thought of impending doom.
I know it has warranty but who wants to go down that road. Apparently GM not replacing all lifters anyways with some poor folks having repeat failures.
Fingers crossed good luck to all.
