The Engine has unexpectedly spun a rod bearing causing the engine to run erratic, low power and knocking. I have taken it to a automotive repair shop and that is their diagnosis. This is the 6.2 liter that has the issue that has recently had a recall issued but my VIN does not show a recall

Transmission would not select gear then without warning would engage. Loud thuds when changing gears. 10spd automatic.

The engine light is blinking while driving on the highway, it comes and goes, I have a video for that. Also it has a ticking noise and I’ve had the noise since I bought the truck and took it multiple times to the dealership, first it was the pump they replaced for free but the ticking never went away, I took it back and they said that all the trucks tick like that, and all that should be documented. Also while sitting still it sounds like the truck is shacking just a little. I have an appointment to which I have to pay $250 for them just to look at it. I think that my truck should be up under the new recall for the 2021 Chevy Silverado because my truck is knocking and also throwing off a blinking engine light.
