So, the shop has had mine for 2 days and as you can expect nothing has been found as of yet. They say batteries tested good, cables pass resistance test and all cables are tight. Mechanic is periodically going by truck and remote starting. None of the symptoms have happened since jumping it off. They are saying it possibly went through reset. They are keeping it tell Tuesday and will let y’all know more then.

So I picked up my truck today after it being in the shop for 6 days. They did an update that was to fix the black screen after remote start. It seems to be fixed.They thought that the USB port was faulty because I had a problem with Apple CarPlay not working. So it was changed out and still have a problem with the Radio recognizing my phone. They plugged a test device into the port and still no recognition. I need the truck tell next Wednesday and will bring back in for them to call and work with Tech support. Mechanic believes it is the radio. It will also show phone is connected by Bluetooth and will not play media even though phone says it is. Will check back in next week.

My screen went black after remote starting a few weeks ago. Once I shut off and restarted the screen returned to normal. No other issues at the time. Haven't driven my truck in a week. Went out to start the truck and nothing. Tried to jump start it and nothing but clicking. Going to give the dealer a call in the AM.

Hopefully, I get my truck back tomorrow. Dealership told me they completed a software update and everything checks out fine. They want to keep it overnight to make sure. I hope the problem is solved.

I had my 2020 2500HD HC in for oil change and the next morning after remote start, the infotainment would not come on.  The infotainment used to come on when on ACC or engine start from the ignition, but would not any more.  I called the dealership and two "Master Technicians"  stated this is how it is supposed to work.  According to them, you have to shut the truck off and start it from the ignition to get the infotainment system to come on.  

So, after being tongue-lashed by the dealership, I decided to reset the truck by pulling the negative terminals and low and behold, the infotainment comes on without turning off the truck now.    "Master Mechanics" can't know everything, but this back-yard shade-tree mechanic go to move on all electronic issues is pull the battery.  I hope the rumored upcoming update fixes these glitches for good.

Two days after my truck was parked wouldn’t start. Boosted it and drive it to dealer. Took them three hours to figure out what you guys all told me. Updated from version 148 to V150. Seems to be working great now. My advice is if this happens to you before you let truck sit ensure you have restarted manually or will die. Thanks again everyone.

    • While waiting for parts I have been working on installing the AC compressor, new accumulator, and orifice tube. Also changed out the high side ball valve (original). The orifice tube that was in there wasn't too bad. Slightly dirty, a little bit of junk, but not blocked. Glad I changed it out.   The accumulator, which should have been a 5 minute job, may have just burned $50. Put some PAG in it, wrote the date and mileage on the side, fresh o-rings and gooey'd up the threads and rings with Nylog. Got everything connected and snugged and was going to vacuum down the system, and....   My manifold gauge won't fit on the port. It's not an R12 service port. It LOOKS like an R134 service port but the diameter is a hair too large. There's a sticker on the accumulator that says it's designed to be used with R12 and R134a systems only. So it's not R1234yf. Even if I reduced the diameter slightly with a file, the shoulder on the port is too large so the quick-connect valve won't lock on. I'm stumped. It's going back, and 50/50 on if they'll give me a refund.   Also, I did a fuel pressure test.... Key on, the gauge spikes to about 60psi and quickly bleeds off, like 2psi per second. The fuel isn't going into the plenum, no smell, starts fine, so I'm guessing there's a bad check valve in the pump and the fuel is just draining back into the tank. oh, hell. But, it shouldn't be a problem, pump primes just fine and the truck starts right up. It just means I can't really ever use fuel pressure to verify a leak at the injector or intake.
    • Got this yesterday out of nowhere. Truck is a 25',6.6 gasser with 8k miles.  Only semi anomaly is that the truck had been sitting, uncranked for 6 days. Elec Stability Control showed immediately upon cranking, not while driving. No drivability issues, just the message. Battery didn't seem to be weak when cranking over.  I drove it, killed it, let it sit a few hrs with no avail.  Truck is 100% stock. No damage. 
    • This can be done.  It is not cheap and requires an instrument cluster swap with custom programming, new steering wheel with the controls on it, and a special jumper harness.   The cluster upgrade - 12.3” Digital Cluster Upgrade – 2022.5–2026 Silverado / Sierra (T1 Refresh Pickup) - WAMS   The wheel upgrade - Steering Wheel Upgrade Kit – 2022.5–2026 Silverado / Sierra (T1 Refresh Pickup) - WAMS   The column harness upgrade - 2019 - 2026 Silverado / Sierra: Steering Wheel LIN Bus Harness - Harness Dr. - DIY Done Right     The problem with doing all of this?  You pretty much can't have any programming done to your truck that involves the cluster ever again.  The dealer won't be able to program the cluster as GM's system will only pull data for the cluster the truck came with.  So it would be advised also to turn off over the air updates.   TLDR;  Should have bought an LT double cab?  You'd have a power seat, the wheel controls, the cluster, all things that you've been seeking in your various posts so far about your new WT regular cab.  
    • I was unaware of that, thanks for updating me.
    • Yes.  The 2.7 Turbomax has Active Fuel Management.  It is NOT the same as the V8s.  Totally different system.     Here is an article from GM when the 2.7 came out explaining the cylinder deactivation and the valve lift system.  Starts at the section called "SCS Valvetrain":   New Turbocharged 2.7L 4-Cylinder Engine Powers Full-Size Trucks – TechLink         This is an internet myth going around.  It was alleged that some 5.3s had this mystical 8th digit of the VIN as an "E" which somehow meant it had a new one year only 5.3 that didn't have DFM.  The writer of said article and the person that made the claim conveniently can't count because they posted the VIN.  The 8th digit was a "D" which meant its still the 5.3 with DFM.  The 9th digit of the VIN was an "E" and the 9th digit isn't the engine code.  At all.
