Wanted to post my displeasure with GM for a 15 year history of camshaft and lifter failure in AFM vehicles. To lose a camshaft on a vehicle that has had all service done, and oil changes well in advance of OLM, is a gross miss in engineering.
Dealerships indicate that this is a regularly occurring issue, and yet 15 years of history still hasn’t brought about a redesign.
I am a 45 year GM customer and, sadly, this may be my last GM. Yes, warranty fixes it, but the lost time and inconvenience, not to mention out of warranty expenses makes me realize the GM does not appear to take this seriously.
C’mon GM, you can do better. Would love to hear GM reply to this question!!!!

I have a 78,000 mile 2019 Sierra with the 5.3 that is in the Dealership getting a complete engine replacement due to this issue. It had been a great truck until this point with no issues. Suddenly I had a misfire, strange noises and blinking check engine light. Brought immediately to dealer. LIfter had stuck, bent push rod, scored camshaft and allowed filings into engine. They are replacing with a brand new GM engine. GM is paying about half. This truck has been serviced regularly at the dealership with proper oil. This should not happen. These engines if properly maintained shoudl last 200,000 miles. I have been a loyal New GM purchaser since 1988. 13 new vehicles plus a few used. All GM. If GM does not step up further, it will be my last and I will continue to tell the story.
Is there a proper preventative measure for this?
