NHTSA Complaint #11696869 — 2015 GMC SIERRA 1500

This occurred 5+ years ago. Coming home one night I had a sudden loss of power with the truck and barely made it home. Was able to limp the truck to the dealership the next day and was told that one side of the engines lifters had failed. Prior to the failure I had noticed a ticking sound coming from the engine that was becoming increasingly more prominent. It was several thousand dollars to repair. Fortunately the failure occurred near home, not on the freeway where I could have been dodging cars while trying to limp the truck to the shoulder. Some online research while the repair was being done revealed that several other owners with the 6.2L engine had the same problem. When I mentioned it to the dealer the response was that they had no bulletins from GM on the issue and I was stuck with the bill. Got the same response a year or two later when the torque converter on the transmission went out. The reason I am reporting it now is I saw that GM is recalling 6.2L vehicles with lifter issues but not back to 2015 even though the issue appears to go back farther than that. They claim it's limited to a specific run of engines for the recall. They have been having various lifter problems for many years that have put drivers in danger when they fail but refuse to acknowledge it. As for the repair they made to the engine I've driven another 70 K miles and the ticking has started again. I fear another failure. Please note that the date previously given for the incident is my best guess.
