What does AFM scare everyone? I’ve never had an issue? I’ve own a 08 Tahoe, a 10 Denali XL and a 15 Yukon....
I guess it's all the engine failures that are being reported. I still think, however, that not all will fail and the failures are the ones that are making the most noise, not the ones that are working fine. Sure, the failure potential is there and I recognize that, but that will still not prevent me from considering buying one.
My wife's 07 LTZ didn't have issues, the 2010 doesn't have issues and neither does my 07 Silverado. Maybe I've just been lucky so far. Who knows... Just as a precaution, though, I have and will also in the future always disable AFM asap after purchasing one with it.
