Anyone have problems with AFM lifters/cam on 2015 and up 5.3 GM engine?

Where their made/assambled. 1=USA. 2=Canada. 3=Mexico. I have had many vehicals over the years. Not 1 was any dam good when made/assambled in Mexico. I’ll never ever buy 1 again with the dreaded 3. I have many friends and relatives that feel as I do. 1 of my friends didn’t make it 100 kilometers when the tranny crapped out on the way home from the dealer. Brand new truck. Kim
