“Engine misfire, AFM lifter collapse, defective AFM/DOD lifter technology. The three diagnosis I have had done to check for multiple opinions have all come back the same with a collapsed AFM lifter causing camshaft damage”
“The 6.2 L engine on my 2017 Cadillac Escalade failed at around 97,000 miles. I took it to Heritage Cadillac dealership for a diagnostic check and had it repaired. The engine had a broken engine rod and lifters damage to the engine”
“The engine is a 8 cylinder 6.2 liter. It starts out using 8 cylinders and progressively drops to 4 at highway speeds. The lifter failed, seized and gouged and ruined the block and camshaft. This preventable repair necessitated an entirely new engine”
