Same issue called the dealer and they said that was strange ha.  They need to have the truck to diagnose but I'm not hopeful. The infotainment system on these trucks are getting worse not better. 15, 18 and now 20 Sierra Denali all have had problems with phone and syncing!  15 was the best but last 2 are terrible and my truck is my office so I need it to work...

Each time I start my 2019 Silverado, many of the contacts do not load. It varies each time to which contacts load and the ones that don’t load

2019 ltz here.  Mine wont load any contacts at all unless on android auto and then it has to relearn every time.

I was having this problem until today. Seems the newest IOS 13.4 update fixed mine.

Thanks hotrods37 I'm going to give it a try.  I typically wait until the kinks are out of iOS updates but this is encouraging...

I have IOS 13.4 on my iPhone XR and still having contact sync issues.  Picked up 3500HD AT4 on March 20 and have issue since driving away from dealer.  Been on the phone with Onstar and apple with no fix.  Truck is in at dealer now as they are getting GM on the phone to help.  Reading the previous posts, I'm not holding out a lot of hope that this can be a simple fix other than replace the radio.  Will advise later what the dealer comes back with.

Yep, no change with 13.4 getting a little perturbed. Very inconsistent when I get in the truck sometimes it sync's up other it doesn't recognize the phone. What can we expect for 70,000 dollars!!

Brought into local GMC dealer in Twin Cities.  They spent hours on the phone with GM tech adviser.  Final resolve was this from GM:  "Advised GM is aware of this issue with the iPhone contacts on the 2020 IOT radios.  We have been seeing that this issue may be something engineering has to investigate.  NO REPAIR IS AVAILABLE AT THIS TIME.  AS ADVISED BY OUR STAFF, CUSTOMER TO USE APPLE CAR PLAY AS WAY OF CIRCUMVENTING RADIO ISSUES UNTIL GM RESOLVES THE PROGRAMMING SITUATION.

 

Service manager at dealer said that it could be months or longer for GM engineers to fix being there is no official recall's or notices at this time.  While I am still able to drive the truck fine, and for that matter love everything else about it, I do find it frustrating that one has to have a work around to circumvent an issue that GM knows about, and admits to knowing about, but doesn't seem to have any urgency in finding a fix.

Thanks Hog, and I hate to say this but I think its time for me to look at other makes the next truck around.  Getting tired of paying big bucks for lackluster performance.  Thanks for your insight...

Have you had it in to the dealer yet?

    • With large equipment or deep mud it is more of a use the higher gear to avoid spinning tires, getting stuck because of spinning tires and doing damage to your machine. The idea is if you run out of torque before you spin tires you can still downshift for more torque. If you are just spinning your tires in the lowest available gear you are stuck and things break.   Automatic transmissions, traction control and electronic transfer cases change the calculation a little as you the driver have less control over each piece. 
    • are there any codes? with lots of rust, perhaps disconnect/clean both sides of the connection/examine cable ends (the wires) for corrosion going into the sheath & replace if necessary/reconnect ALL the power AND ground cables between the battery, engine, frame, cab, fuse box and starter charm.li (website) has a no-start diagnostic procedure you can work through to get it working.
    • Its no wonder you've gravitated to the oil types and brands you have in later years after trying certain brands and one being a specialty oil or at least very hard to come by up here and the other would have been a commonly found oil of the era and the vastly different outcomes as a result to using the vehicles in question the same distance for an OCI . It shows what marketing hype can do without actually having the product to back up the claims and that is no different now with the insane claims that are written on the side of a bottle of oil from some of the off the shelf oils.    What has surprised me and I was already finding this out before I bought my truck with the GDI engine, that this newer fancy technology that seemingly would suggest better fuel economy/emissions with this high pressure spray of fuel is not in reality kind at all to the engine or at least the oils life. Yet they insist on claiming long OCI with this technology just like they did with the port or similar type fuel injection systems when in reality its a step back in oil life to have a GDI system.    I think the mistake your making Grumpy is that your not sending your samples to Blackstone and getting the feel good glowing report that you can run it another 1000 or more miles and then send another sample where they say run it yet another 1000 miles and on and on it goes until your sending in something that looks a lot like road tar and then they may suggest you change your oil within the next 1000 miles 😆
    • I am guessing that engines of that design back then had a better ability to be abused and survive longer than a new design engine with the long timing chain and the overhead cams and phasers etc. But I would never guess that an engine could go that far and not fail spectacularly or at least die a slow death. 
    • In the 80's 90's I'd run Honda's 7,500 miles between changes using Red Line HP 5W20 and do it for hundreds of thousands of miles with issues. Back in the day it was an SAE 20 with the HTHS of a SAE 30 and SN add load. It was also very polar. Oxidation VOA was over 120. Besides those motors were SPFI and lean burn tech. I could have likely run it longer but never did.    We had a Toyota bought new I ran on Pennzoil's latest and greatest synthetic of the day with "Penthane". A made up word for a very low dose of PAO. Tried 7,500 mile OCI's in that Group III/VI chemistry and the rings tapped out at 90K. Rocker box wasn't as bad as the one Punch put up but it wasn't good either. Also a SPFI motor.    I'm around 3,750 across the board on these GDI monsters and the oil it tapped out by then usually on TBN/TAN crossover and color. Red Line HP Euro.    The AMSOIL SS brochures tell you to follow the OEM values for the service class but that it can be run up to 25K if monitored. I can't imagine what motor could go that distance and not tap out. I've never owned one.    Yes, I know. Lot's of people do. I'm just not going to be one of them.
