If you look on your On star page for your truck it will show if its open even if you dont pay for a plan (I dont) 

Follow the link if you get monthly e-mail reminders. 

I thought of that after reading your previous message:

The completion date was the day before I picked it up. The other 'programs' (aux' battery wont charge for example) & recalls (tailgate may open) were completed by the dealer who initially had the truck.

 

EDIT: I had looked @ the 'Incomplete' tab, but hadn't thought to check 'Completed'.

You sure you aren't in tow haul mode? At least on mine, the battery gauge goes away and it replaced with ATF temp while in tow mode.

What "software update"?  The Serial Data Gateway recall?     Towing MPG seems fine if you are gas.  Diesel, hard to say, but a 5th wheel, 12ft tall at 70mph, I hope you aren't expecting grea

Got my 2024 LTZ L5P flashed while getting an oil change today (25k miles in 14 months, servicing every 5k). Took an hour+ over normal service visits. Nothing noticeable to me, other than that the Andr

My main battery was replaced some time ago and the aux battery update was also done this summer but I still have a main battery that will drop below 12.0V charge in 4 or 5 days of no use. The aux battery stays around 12.6

I am hoping this update corrects some of that. Not sure if it is relevant but the trucks is garaged in my all metal pole barn/faraday cage so it may be trying to connect with Marys mothership and it cant get through (read that with the highest level of sarcasm possible)

Don't worry, I have nothing good to say about her. And people thought Roger Smith was disliked...

Does GM even build any cars? No mention of EVs 🤔

Its technically not a recall, GM calls it a customer satisfaction program N242435631. My understanding is that its a new program designed to improve communication between modules and correct a possible situation where the battery may be discharging during a failed update. ( I believe is similar to what happened on some of the Colorados) There wasnt any information about the number or build dates of the effected trucks. I believe this was a mid year change once the new program was written so not all 24's will need it. 

Thanks 64BAwagon !

Today I got the email about the software update. I was planning on stopping @ the dealer on an unrelated matter, so will ask about this in relation to the 'completed' issue on the OnStar report.

Yes, the update had been completed before the sale. Service writer said that they had seen that in the past. Customer gets an email notification after the recall or campaign work had been done.

I took my 2022 Sierra in for unrelated service. They updated my software due to the recall. Radio started cutting off for 15 to 20 seconds and rebooting.  Control panel was slow in responding. Bluetooth calls dropped.  Things were out of sync.

 

So I took it back last week to have it repaired. Some improvements but more of the same. I took it back yesterday, they want to replace the radio at $1300.00. Hell no! My radio worked perfect. GM owes me a radio. If your system is running fine, don't do this update....

I just had my recall performed yesterday and they have since removed the radio reprogramming as of 10/25/2024 as a 5th revision to the recall. So far everything is going great. I noticed the speed of my Apple CarPlay connection greatly increase. I posted as a new topic as well in hopes to inform others when they still have android version 10 after their service.

I think it's unnecessarily expensive and don't see the point in overpaying for such an upgrade.

The upgrade is no charge.

I received my 2024 2500HD 6.6 gas in July of 2023 and I received the software update letter recently.  I took the truck into the dealer last week.  They also completed the replacement of the trailer brake controller, which was another letter I received.  I didn't notice anything different on my 25-mile drive home.  I specifically saw the volt gauge because I recently added a DC to DC charger to charge an auxiliary Lithium battery and I was keeping my eye on the volt meter. 

 

Over the weekend I drove the truck again and noticed that the volt gauge had been replaced with a transmission temp gauge at the bottom right of the dash.  It is the second gauge over from the right, with the 4 gauges across the bottom.  I went through all the dash display options several times trying to find a volt gauge and found nothing.  I am using the classic layout with the "maximum" lower gauges option.  My assumption is that the software update wanted a more permanent transmission temp gauge and for some reason doesn't think the volt gauge is important anymore.  I would prefer to have one again.  Has anyone encountered this?

I just checked my truck & that is the same situation in tow/haul mode.

I have an add on USB/Cig lighter plug that displays volts plus I have it on every page of my Scangage3.  Anything the dash offered was pretty much a bar graph with no numerical value which is useless IMHO

      AFM Experience

      By KARNUT · Posted

      The problem with failure rates or increase failures are there’s people who don’t have a problem. What are you doing wrong they say. We had 4 5.7 GM diesel’s in the family when they came out. One was flawless. My uncle who happened to be the most abusive. Early rotary engines were known to use oil. I abused my first car so bad in six months I replaced the clutch, transmission and rear end. It didn’t use oil. My brother in law has a 2013 Tahoe and an older Yukon. The Yukon has 280K miles. The Tahoe around 175K. He runs them to about 300K. If his lifters fail before that time he would consider it a failure. My Hondas, I know people hate it when I mention them. Identical engines. One with cylinder deactivation one doesn’t have it. One shudders when the eco light goes on or off. Cylinder deactivation. But wait! According to the web. It can happen with lock up too. So now people in the know are changing the oil and transmission fluid more often. Then you read it could be a programing issue. So what do you do? There’s lots of money involved. I see three ways to deal with it. One only works if you don’t drive lots of miles. Lease, never get out of warranty. Or only buy older vehicles with a good track record. They all have bad runs. Usually when there’s a change. Even Toyota and Honda.

      Question @diyer2 on this line if you please. Are you saying the shudder is the system turning on and off at the frequency of the shudder? Guess I'm asking if you are saying you have seen it do this with the bi-direction scan tool in graph mode? If so have you been able to discern the 'trigger'. Something is telling to cycle rapidly.    My truck just started doing this recently. 197K on the clock. My response has been M5 anything under 55 mph. I treat it like a lugging stick shift. Gear down and let it spin a bit. Engauge M5, then tow mode and then M6 lets the trans stay in 5th but the AFM is active. Smooth like Skippy.    My thought was that as a machine ages the friction gets lower and as the system is load based, the lower friction would allow it to turn on at ever lower rpm until it reaches the lugging point. And yes I am ignorant of any minimum rpm requirement for the system. If you know that would be useful information.    As you know I run a Scan-Gauge II which allows me to watch the On/Off of the signal to the VLOM. While in the shudder mode I'm not seeing is cycle at that frequency or at all for that matter outside the triggers @newdude posted a few years back. Now is it possible that the refresh rate isn't fast enough to catch it? Maybe. It is why I asked my first question about graphing and trigging parameter.     As we have observed from members here the failure point is all over the map miles wise as you note yourself in your opening post. That by itself begs a few questions like fellows that comment on these lifters failing even after the system has been disabled. Long after. 😬   https://www.enginelabs.com/news/tech-tips-replacing-ls-active-fuel-management-lifters-with-melling/   The Gen5 lifters operate the same as the LS versions. In fact they are the same lifter.    https://www.enginelabs.com/tech-stories/sorting-out-gen-v-lt-lifter-failure-with-a-simple-valvetrain-fix/

      14-18 Sierra 1500 Heated Steering Wheel Help

      By SwitchBladeSierra · Posted

      UPDATE 2: Steering wheel control backlights and control of the cluster can supposedly be achieved by adding a wire to pin 20 of the cluster and tapping it to pin 2 of the main clock spring harness. I'm going to give it a shot - will update

      Seems to be Missing a lot of Updates

      By newdude · Posted

      GM Global A pickups 2019-2022 can do OTA programming for the radio.  GM VIP (GM Global B) can do OTAs for almost every module on board.  So a 2022.5 and newer pickup can do OTAs for recalls like the 2.7 fuel flow recall.  EVs get OTAs that improve one pedal driving, radio issues, HVAC issues, updated battery management software, etc.     So age of the vehicle/what GM electrical platform its on will alter what amount of updates can be pushed on OTAs.

      Upgrade to a 2026 AT4 with the 3.0L Duramax

      By Blade8971 · Posted

      Thank You.   So far my new ride is making me look like a genius for going with the 3.0L, as my first fuel refill occurred over three weeks from when I took delivery.  This engine combination is very amazing.  So far no issues and had not done a regen yet.
