I have similar issues with my '24. Took it in - tech fixed factory align issue at 500 miles. Took some away. I drove exact same optioned truck (max trailer w dual alts) out and was worse so I went home. I then did steering stabilizer and hit all grease points and did King 2.5s. A little better, but not as good as my '20 AT4 3500 ( which was hella smooth ). I chalked up to dramax vibrations (though my '15 and '20 were smooth), but seeing the gassers on this thread got me looking deeper. I took a look at Cognito PISK install instructions and it said there are two types of center links - 1 has a bushing for steering pitman and one doesn't - my '24 does not. I looked at parts diagram and one on '24 is most recent. Why did older ones have the bushing? Was that in my '16 and '20 that were smooth? Since it is on steering hole, is that what softens steering input? I saw on Moog site that the bushings are notoriously problematic for wearing out. Is that why new ones no longer have them? Does anyone know when the ones with were replaced with ones without? So I am thinking "what if I put in one with bushing"? Or, should I just go with kryptonite hd one? The kryptonite one changes to dual ball links - will that loosen steering too or absorb vibrations? Wanted to put this out there and gets thoughts ...

Are you still liking the SmartCap? I have had both ARE and Leer on past GM trucks and this was interesting to me ... Any tips?

Hi - All. Had amplifier replaced per PIT6101L last week - fine for a week - issue back today !!!! Given the # of these all over forums and PITs - how do we get a resolution? - dealer wants me to drop off and give me a loaner - hmmm - not sure that is worth the time given it is most likely a software issue? What are others doing?

PIT6101L - I had issues - they did Y172 update - fine for a bit - issue came back - thankfully was doing it when my appt was and they replaced amp per PIT. So far so good. I took a video of it happening to just in case (tip: make sure phone isn't connected to BT or CarPlay as mic won't work). Go to another dealer - PIT is clear, if no audio, replace amp.

TY!

@newdude - thank you for your help above. Condition just came back after several weeks and Y172 Update. Can you send me PDF of PIT6101J? I can only find up to H on web. Want to have in hand before next dealer visit. Previous versions said to check Julian date first and then replace. That will be two trips for me. Want latest version in hand that says replace. Also, do you know way to confirm amp p/n for 2500 Denali Ultimate? The online sites only show 1500 DU. iayh Bob

Hi - Just had this resolved at dealer. There is a new recall (N242435631) that also includes bulletin 24-NA-117 to upgrade radio. I asked about bulletin when recall done and they said it was included. I double checked radio version and it was updated. I have '24 DU and 50% of time audio went out last time couldn't get reset to work. No issues since this recall was done on Monday. Cheers, Bob!

Had recall done. Actually showed up with radio sound not working even after several resets and safe mode. Of course, when tech got to it, it was working. I asked them to do the 24-NA-117 (superseded 100) and they said it was included in recall N242435631 I went in for anyway. How can I check to see what radio version I have now after service to verify?

Thank you @newdude. Looks like fresh recall (N242435631) hit 9/10 for my truck for it. Getting it Monday. I appreciate your help! Bob

Hi - I have a '24 Denali Ultimate 2500 with 700mi. The 2 of the last 5 times I've driven this week I've had no sound. I have to put in "safe mode" to get it going. The hold the mute button to reset doesn't restore sound, just resets. Had to use safe mode again. Are others seeing this? I saw in another forum that someone had to have Bose amp replaced as it does more than just amplification. Don't want to take to dealer to show me how to reset in safe mode or "can't replicate" without being armed with more knowledge. Any thoughts? Cheers, Bob!

Bringing to the top. Anyone have any further info/ideas? @Texas GasserDid you ever get it sorted out? iayh Bob
