  1. Will the Disabler void the warranty? I still have 8K miles left. It was the fuel lifters. They even replaced a rod on the first failure. I have seen examples of GM giving an extended warranty because of this issue. Is there a way of requesting this? I asked at the dealorship and they just said NO. I would rather not pay the $4000 for the extended warranty..
  2. I am considering trading the Tahoe in for a Yukon Denali XL. Is the AFM with the 6.2L any better? Any thoughts from you guys?
  3. I purchased a 2016 Chevy Tahoe LTZ about 4 months ago. About 2 months ago the fuel lifter went out in the #4 cylinder. The dealership did all the work after getting the parts, which were back-ordered for 3 weeks. Thankfully it is still under warranty. I drove it 3 weeks and the same thing happened again in cylinder #6. I think the AFM system is complete crap. Both problems occurred when I gave it some gas to merge into traffic. I asked the dealership if there could be a problem with the head, but they said they'll look at it. I love the vehicle but am extremely concerned about ongoing problems.
