Some people have problems with it in the first 50K miles. Others go 300K with no issues. The system works with oil pressure so when one of the AFM lifters fails and wipes the cam, low oil pressure (another common issue) is often the smoking gun.I own a 2012 Tahoe LT 5.3. I would like to know at about what mileage can I expect the AFM to start giving me problems. Or has GM worked this out?

Just trying to get their average MPG fleet wide high enough for the EPA.What is, 1 mile. Thank you Alex. Let's move to "What was GM thinking", for $800.

Yep.Oh I know, it's just a classic case of good plan (mpg) poor execution (AFM) and really adds to my love hate relationship with GM V8s.
