Best thing I ever did was tune the AFM out with the Diablosport Intune. Same economy, much smoother, significant power gain, etc.

all I got in the mail was an explaination that they are extending warranty on a powertrain condition to 10/120k of course if you bring it in and it is not that exact condition you are on the hook for it of course lol http://www-odi.nhtsa.dot.gov/acms/cs/jaxrs/download/doc/UCM429727/CSC-10047220-3332.pdf

 

That is for the TPS, not related to the AFM system directly.

The one I got was about the dip-stick possibly cracking due to vibration and causing an oil leak / fire. The put a little O-ring on the dip stick some where to reduce the vibration... I didn't see them do it (our dealer does the waiting room thing). One about the rear-axle pin replacement, but my truck was not in the VIN range. The only other one I remember receiving in the mail was the Dexos info card, saying we should use it even though our manual, oil cap and engine don't say its. My 2011 was made before Dexos oil caps showed up on engines.

 

I don't remember an AFM ones..

Mine has done that since day one.....normal is what I'm told

Definitely not normal. When mine switches between 4/8 cylinder-mode I cannot tell.

As soon as I mentioned it, the shop foreman said that "It was normal, and GM even rearranged the firing order to accommodate the AFM system, and that I've may have noticed that the idle isn't at smooth as my '06" (sure do miss that truck), and he's right, the idle does seem do be a little off

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.

      2026 6.6 L5P oil cooler leaking oil at 4,000 miles

      By Brendan C · Posted

      New to diesel trucks. I happened to find my oil cooler leaking oil externally with only 4,000 miles on the truck. I didn’t realize this was an issue until I started researching it. Dealer is going to replace it under warranty but I’m wondering if there’s anything GM is working on to fix this issue. I’ve heard the oil filter used is the same as they use on their V6 motors and that’s what is causing the problems. Should I switch to a bigger filter or keep using the OEM recommended?

      Seems to be Missing a lot of Updates

      By Vu1can · Posted

      So, GMCustomerService:  Judging by the Update History pictured above, is this truck missing any updates that it actually needs. If it's just for the infotainment system, the radio is working fine and no trouble with SeriusXM. and Android Auto is working fine wirelessly with my phone. Some months ago, an update notice was sent to my truck. I approved the update and it finished saying that the update was successful, but it seems that whatever that update was, it didn't actually get installed - at least not if I'm to go by the Update History shown above.   So, again, are there any updates that this truck really should have? I've checked with my dealer but they're reluctant or commit to anything and if I want them to check, they require a $200.00 fee just to check it out and then I'd have to pay for the actual update(s).    Ignorance is bliss, and if none of the updates goes to fixing any mechanical discrepancies, I'll just leave things as is.
