Yeah I get the same thing since I’ve had my 22 chevy 2500. IOS infotainment. It’s very annoying I don’t have wireless charging so I plug in my phone anyway, I may just try to disable wireless CarPlay and see if it connects. So far best I could do is set up an automation that turns wifi off and then on again when CarPlay connects. It usually then forces a connect with the truck wifi. At least more consistently than not having it. But I need to play with that more.

Had the same issue with 2021 Yukon Denali and finally got it fixed.  Dealer replaced and reprogrammed the OnStar module and now it is working perfectly for last 2 weeks.  Used to disconnect CarPlay multiple time on way to work (in the same places), no longer any drops.  Hope this helps!.

Can somebody please tell me how you got your dealership to replace and reprogram the OnStar module? My dealership is refusing to do anything and keeps trying to tell me it’s my phone. It is not my phone, it’s the vehicle. HELP!!

Is there any way you can tell me which dealership you took it to? My dealership is saying they don’t see this issue in their database of “all logged vehicle issues” so it must not be real… and they refuse to look at this blog. I was hoping that if I could tell them the dealership you went to, they could call their service department and help coordinate an actual resolution.

I have a 2022 AT4 2500 and it has the same issues. It won’t connect when I’m in the truck, but if I leave the truck running and get out while I’m on the phone, then it connects to the truck and I’m missing the conversation, or they think I’ve hung up so they do the same. If I’m on the phone, it is continuously switching from handset to CarPlay, it makes it impossible to talk on the phone. If I turn everything off, it all comes back on and starts switching between the two again. It’s frustrating enough to make me buy a Ford, almost. I agree with the person who said the truck is too expensive for this crap not to work. I’ve been to the dealer and they’ve checked it, I’ve been on the phone with OnStar for hours trying to figure it out. Also, when I get in the truck, my phone will not automatically connect to the Wi-Fi. I have to open it, select my truck and then connect it. My phone connects to every other network it has ever been logged into automatically, except my truck. It’s aggravating to no end.

Alright y’all…I’m about to blow your minds with this one!!  It’s 5G interference!!  You know that thing you heard about in the news and the new 5G cell towers near airports interfering with aircraft radio altimeters…it’s the same thing.  MANY of you have stated that the Wi-Fi interference usually happens in the SAME places around town…next time look around…I bet you there will be a cell tower near by, then look at your phone…bet you’ll have full bars of 5G!!  I have a 2021 Silverado and the exact same thing happens to me.  If I wasn’t in aviation I wouldn’t have figured it out.  Nothing will fix it until GM updates the Wi-Fi equipment in the vehicles.

      This is interesting. My quote tagged here is different from my original quote. After I’m driving them longer. That isn’t me. I don’t talk that way. I definitely wouldn’t express myself that way. Interesting.

      What have you done to your K2 today?

      By UrbanRage · Posted

      I have the same running boards on my truck and I do agree they are bulky. I also find myself stepping over them when getting in and out of the truck. Besides providing protection to the rocker panels, they aren't very useful.  I will be replacing them soon with the Amp Powersteps.

      OCI, not when but why?

      By Grumpy Bear · Posted

      10 Ford and Chevy engines proven to reach 300,000 miles   You may note a common 3K OCI on this list of gas motors. I skipped over the diesels. Dh'O.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By jake111 · Posted

      Thanks newdude!  By the time manual selection is needed, I'm probably too much of a control-freak to depend on the transmission sensing braking to activate automatic downshifting.  I would be anticipating the situation and already be manually downshifting.   This truck replaced a 2004.5 LLY diesel with the Allison 5-speed.  Putting it in T/H made noticeable differences (when the torque converter locked, upshift points, downshift behavior).  On this 2024 gasser with the 10L1000 I haven't been able to detect much, if any, difference.  Ok, I can never tell now when the torque converter locks up.  But I also don't notice differences in shifting.  For downhills, I've probably already manually downshifted by then anyway.  Since it's also more awkward (than the 2004.5) to engage/disengage I don't even bother.  Or maybe it doesn't really matter with just a 3k lb. camper in the bed?   Thanks also for the list of reasons the charging system might select various voltages.  However, what I am seeing doesn't fall into any of those categories.  It very definitely, and very consistently, rises after coasting/braking.  Maybe not immediately, but not very long after coasting/braking.  Very consistently drops voltage when no longer coasting/braking.  It might also be interacting with the camper battery charging (I might disconnect the camper and see if it changes the charging behavior).  I also need to recheck turning on headlights for when I want to force it to charge the camper.   Another JR, in June I converted the camper to LiFePO4.  Since it's not a good idea to try to charge lithiums directly using truck, I installed a Victron Orion XS DC-DC charger (which BTW is AMAZING!!).  Being cheap, I only had to buy that one item (besides the battery, of course) to do the conversion.  The camper OEM 120v battery charger (only 19 years old and works perfectly) and the truck feed the input to the DC-DC charger (not at the same time).  But I didn't want the camper charger feeding back to the truck so I kept the old separator.  I considered replacing the separator with a 30amp diode but that means more work and might add another 1/2 volt drop.  One thing that surprised me was the voltage drop over the long 10awg wire run, so I can only charge smoothly at 8 amps (because the DC-DC charger is completely configurable).  Another reason I don't want an added voltage drop with the diode.  I might also be a little lazy but all this work is being done under the sink with a small cabinet opening.
