Lifter Failure: I was traveling to a State Park in Northern Michigan when my engine starting running very rough with major power loss. My check engine light activated, and I pulled over as soon as I could. It was dangerous because I was pulling a camper and I had to drive well under the speed limit. The Certified Chevy Dealership discovered a collapsed lifter and Cam damage. They considered this as catastrophic engine failure, and I was completely shocked as the vehicle had roughly 129k miles on it. There was no indication of failure prior to this incident as the vehicle ran perfect. I am very disappointed in GM as I have a co-worker with the same year truck that had the exact same issue shortly after I did. A friend of mine also had this happen with a 2014 vehicle of same make and model. It appears that this is a common issue with GM's newer 5.3 engines which used to be extremely reliable (99-07). GM needs to fix these lifter issues because a newer technology engine should last much longer.
Lags when accelerating. Does not happen every time. Causes safety issues when in heavy traffic. The below date is when it started. It happens very regularly.

My engine has a tick, ,brought it to a shop he told me lifters and its expensive...went to dealer, ,, told me I need lifters $2600 to fix it and apparently my lifter isn't getting oil in it, "from active fuel management" with I have read all over internet that its a huge problem and people have to pay to fix, ,,but wont fix the issue do to the fact the afm cuts the cylinders off causing the lifter to not get the oil
On 26mar2017 I noticed a ticking noise coming from my vehicle. I took it to the dealership 27mar2017 and was told that I needed a new flywheel. I wanted a second opinion because I have never heard of a flywheel going bad in my life. After speaking with a few mechanics we all agreed that it was not the flywheel. On 4apr I took my vehicle to another dealer who confirmed that the ticking was the flywheel. The flywheel had to have been defective at time of manufacturing. It just cracked for no good reason other than it was poorly made. 2012 GMC Sierra 1500 flywheel just cracked out of nowhere endangering the lives of an entire family and who knows who else if it had shattered.the vehicle was ticking after a morning start while sitting idle.
