Blind Spot Detection problems of the 2020 GMC Sierra 1500

I have had no issues with my vehicle since I purchased it in July 2022 and keep up with the routine maintenance on it. About 2. 5 weeks ago I was driving to work like I normally do and the truck started making a knocking noise and all these sensors lights came on the dash. The alerts were saying to service the parking brake, service esc, and that steering assist is reduced and to drive with care. The vehicle also started shaking and would not accelerate properly or shift gears. We ended up taking it to the closest GMC dealership and they were in able to diagnose it just by simply hooking it up, they had to fully dismantle the engine in order to diagnose it. They came back and said cylinder number 4 is damaged as well as the lifters and cam shaft. I am no car expert but it is weird that a car that is relatively new and has the maintenance kept up on it should not experience a serious malfunction like this. What is even weirder is my sister in law has a 2020 chevy silverado where the almost identical thing just happened to theirs and it too is now in the show as well needing its engine and stuff repaired.
