Use heavier or thicker oil I heard is a remedy if you catch it early, swap to 5w instead of 0w

Wow I did have a lifter failure destroyed my cam as well and $4500 down the drain still doesn’t run right. Is there actually a class action lawsuit?

All Chevy has to do is make it possible to turn it off from factory 😭 sport mode is the only thing that kinda helps on our Escalade

Chevrolet and Dodge do the same shit, Ford, Toyota, Nissan all are 8cy s all the time. Junk ass AFM, DOD, MDS are because they can make the horsepower, just cannot meet EPA requirements like the other 3. Shitty engineers!!
