Engine Clicking And Tapping Noises problems of the 2013 Chevrolet Suburban

Tapping or clicking noise coming from engine compartment. Car lost power, bucking with hard shifts, and stabilitrack, abs and check engine lights all come on. I took to authorized repair shop and they found misfire on cyl 4. Changed all spark plugs/wires and cleaned thottle body and tune up as well as oil change. Car continued hard downshifting after picking up. Drove for a week and symptoms reappeared again. Shop is currently trying to diagnose if it's a bad lifter(s) or possibly fuel injection problem. Shop owner admitted that he's heard of problems with gm's 5. 3 engines and the active fuel management system wrecking engines. I have my 3 kids in the car and it was scary almost getting stuck in the middle of a busy street.

My vehicle is only 2 years old. At approximately 85000 miles on a car that is properly maintained it suddenly started to burn out spark plugs. After numerous spark plug burn outs and service appointments I was told that the engine is damaged because the number 1 cylinder was cracked and opening the engine was the only way to confirm how significant the issue was. As the cost and remedy was unknown and longterm fix seemed unfavorable to me, I took the option to replace the engine. I have tried to get to a resolution with gm but got absolutely nowhere. I am in a network of owners of these vehicles and a significant amount of drivers are experiencing the same issue. Some gm service stations have also mentioned that the issue was not corrected until the 2015 model year. This tells me that gm is aware of the issue and has chosen to do absolutely nothing to assist customers with this unacceptable issue. Overview of the many issues: excessive oil usage spark plugs burning out or failing sluggish engine clicking noise in engine prior to fixing the engine, I spent approximately $1500 in repairs and lost wages as I use the vehicle for work.
