More info on the Dealer’s repair pursuant to SB N212353840 which states all 16 lifters must be replaced. After connecting with the Dealer’s General Manager (GM), the Service Manager went back to the mechanic and asked how many lifters were installed? The mechanic produced records showing 16 lifters were installed PN 012698946. This PN matches the PN in the SB which call for 16 PN 012698946. I am satisfied that the repair was done correctly.
I asked if GM might offer an extended warranty on the repair because it was a major engine failure at only 14K? The Dealer GM agreed that an extended warranty was reasonable and said he would contact the GM regional rep.
There is some chatter on the internet asserting that this lifter failure is caused by the AFM/DFM. I am not convinced. However, I do agree with owners who say that they bought a V8 and not a V4. Even my 6.2L seems slow off lights and I am not a “racer.” I have purchased a Range Technology AFM/DFM eliminator. If anyone is interested in how this changes my Sub’s 6.2L performance, then let me know and I will continue writing comments here. I am not one who writes comments anywhere. I especially dislike the ad hominem requests for reviews that retailers email to me. But, if there is interest I will comment here.
Thanx and stay safe and well.
