I recently bought a used 2016 Sierra Denali 5.3L 4x4 in March with 48k miles. Truck has been great until yesterday (now 52k miles) when I ease into the gas it shudders and shakes like crazy until i punch it. The tach is bouncing up and down and it doesn't matter if it's in v8 or v4. It almost feels like it's a misfire but it's weird that it only does it when I'm easing into the throttle or going uphill. The truck has the 8 speed transmission. Has anyone else ran into something like this and would the manufacturer warranty cover the fix for this?

Truck Does Not Run Right...Tachometer Bounces...Hesitation from the start...Going up hills is Jumpy...Skips and Bucks, Feels like truck is Misfiring...Transmission shifts are consistently Rough and Random... Dealership confirmed the problem after test driving and they then found TSB #PIP5457C: Surge hesitation Chuggle Misfire Feeling With A Light Tip In - (Feb 10, 2017) which they believe match's the problem. The Dealership says GMC is aware of this (TSB #PIP5457C) the cause is unknown at this time. Do Not Know How Long It Could Take To Get A Fix. I called GMC customer assistance and requested a replacement or buyback they opened up a case number for me. They next day GMC customer assistance denied any kind of replacement, trade assistance, or buy back. Closed my case because they do not know what the cause is at this time and do not have a fix for the problem. I was told I must drive the truck (AS IS) until such time a fix is available. They also encouraged me to exercise the Lemon Laws in my state if I wished to pursue a replacement or a buy back. Extremely unhappy with my first GMC Truck and that's a shame because it’s a beautiful truck It just happens to be a Lemon that runs like Crap... Just keep driving (AS IS) is not what I paid for...I hope someone else has any insight to how to fix this problem. I hope others will post there concerns as well so we can get these trucks fixed or replaced...

Hello all, This is my first post on this forum. Last year I bought a 2009 Chevy Silverado 1500 Ext cab LT with a 5.3l V8 that is Flexfuel capable. Well, I never intended to use flex fuel, but last week, I did so on the spur of the moment. We drove about 3/4 of the tank gone. Then as I was pulling up to the gas station to refill before going out of town for work, my truck's idle began dropping and feeling like it is about to stall out at idle. This happens whether park is engaged or not. I filled up, put some seafoam in my tank and drove about 1.5 hours to work. It continued to idle like this all throughout the trip and even later when I went out and sat at idle while on my break. What could be the problem? I can't imagine that an engine that is meant for flex fuel could get that messed up by it. A side note: we had the transmission rebuilt in January, just in case that makes a different. It has only been a few weeks since last oil change. All fluids were checked and filled up at that time and have been checked a couple of times since.
