Hello Y'all -

 

Friday night, I took delivery of another "suburban" been driving them for 20+ years. Anyway, the new one is a 2016 AWD Denali XL, and I am having a couple issues. The most frustrating one is that the "Safety Seat" alert function doesn't work in either vibrate or chime mode 99% of the time. I have used it on a 2015 Cadillac and remember it being pretty sensitive. However on the new Denali, I can't get it to consistently trigger even when I am trying to. The automatic "steering" and the adaptive cruise control work VERY WELL. However, it seems like the alert system should be chiming or vibrating my seat any time that it is applying the brakes or correcting my steering - it is not.

 

Also, the parking alert is essentially non-functional. I can pull close enough to my garage or another vehicle that I have to fold in my mirrors before it alerts. Most of the time it just doesn't alert.

 

I have read the manual and have the settings correct in the VEHICLE section of the touch screen options. I also have the buttons correctly selected on the dash.

 

Have many of you experienced similar issues?

 

Do your SEAT / CHIME alerts trigger each time that the vehicle makes a correction?

 

Thanks

...so it should be working as you described it. Sounds like a dealer refresh or update to the program.

thanks - is this a "known issue" for lots of folks?

Known issue for some of what you describe, but not necessarily for a lot of folks. With these common day software driven vehicles, occasionally these trucks roll off the line without all of the updates and dealers usually do them when you take the truck in for routine service.

GMC dealer driving to deliver a loaner to me tomorrow, while they take this one back for service. Meanwhile, I stopped by a Chevy store and test drove a LTZ Suburban. Its sensors were more responsive than my Denali, but still nothing like the 2015 Escalade ESV I had for a while. Is there some sensitivity setting the dealer can tweak?

Any fix, mine started. The chime always works, but the seat vibrate defaults to chime half the time.

      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.

      Vehicle Payments

      By ChristopherDobson · Posted

      Monthly payment is only part of the equation. With today's prices and interest rates, I'd look at the total monthly cost: payment, insurance, registration, fuel, maintenance, and expected repairs. A vehicle that fits comfortably into your budget is usually the better choice than stretching for a higher trim. I've also kept my vehicles longer over the past few years. New cars have gotten expensive enough that driving one for 10+ years, while staying on top of maintenance, often ends up being the most cost-effective approach.

      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.
