Parked overnight, remote start next morning, hopped in and accidentally tapped accelerator bringing RPM's up a little (not a rev), and then inserted key and turned on ignition. Put truck in reverse and loud womp-womp-womp-womp with accompanying vibration from engine. Service Stabilitrack message, Traction Control Off message, Check Engine light popped on. I switched to 2WD, no change. Put truck in park, engine smoothed out some, shut off and restarted, put in gear and same scenario as before. Was somewhat reluctant to go back in park.
GM mechanic told me sounded like it was misfiring. Didn't want to drive to dealership for fear of washing out misfiring cylinders, so had it towed. Got a call and they say need to replace pistons! One cylinder has low-or-no compression and oil-fouled plug. I'm having trouble remembering exactly what he said because I was so taken aback and in shock when getting the news. $3000 to replace the one piston! He said might as well do all for another $600 and basically have a new engine. That would get new lifters, too. I am distraught!
The truck has 89K miles, however is about a year out of warranty. It had an oil-fouled plug in the past and using a little oil, but they addressed that with the splash shield under warranty some time ago. I asked them to see if they can somehow repair this under warranty, so they will be checking into that tomorrow. No promises, they said, but they will check.
I asked how this could just happen so suddenly, and he said it's probably been getting this way for some time. I get monthly diagnostics from OnStar, and there's never been any indication that anything was awry.
I'm sorry about rambling on and the disjointed grammar, it's just that this all seems so incredulous and I am just sick. Any advice or help is greatly appreciated.

My 2009 5.3l Has the EXACT issue your truck had.
My truck has 85,000 miles (under the 100,000k warranty) but over the date by 1 year 2 weeks.
My dealer is planning on opening the engine monday 01/18-16.
Thanks for giving me some hope that GM might help me out.
Did you truck burn oil before this happened?
My 2009 has burned 1 quart of oil every 1000 miles since new. The "TSB fix" which the dealer performed on my truck at 40k miles did not work, oil consumption continued. Deal said 1 qt per 1000 miles is acceptable.
I hope GM does the right thing and treats me as fairly as you got treated.
Do you have any info that might be able to help me out with like TSB numbers, recall notices or anything that you can think of.
Thank you so much!
