more errors than I can shake a stick at

My wife called me and texted me a picture of lights on the console of my 2012 Cayenne. I told her to drive home as she was only a mile or so away. She called back and said the car was making noise and bumping. I drove over and observed the lights she mentioned and when pulling out slowly from the parking spot it seemed the brakes were grabbing the wheels randomly. I put the parking brake on and off but no difference. I took this video:
that showed the various errors that were cycling on the screen. I drove home and it sits now. I contacted dealer. Car has about 14K miles. Any thoughts?

I had the AWD System Fault last week. I pulled over, put it in offroad then back in normal, shut the ignition off and restarted. Gone. I hope it does not come back. Too many electronic gadgets seem to complicate an otherwise competent performer.

Not battery. That was my first thought and put it on the charger but judging by the time the charger hit 7 green lights, it was already pretty well charged.

I tried starting up a few times and eventually everything but the ACC came back so I tried driving it. NO GOOD! Idling was ok but as soon as I even touched the accelerator, both front brakes (and maybe rear) engaged and car abruptly almost stopped.

ha ha! LOL.

So I had the car towed to the dealer. Fault in PSM for R/R speed sensor. Replaced all 4 speed sensors per technical bulletin!

They updated PCM to 3.43. My loaner 2016 had 4.53 so I'm wondering if anyone with 2012 has a PCM newer than 3.43?

They also did multipoint inspection and all seems good.

I had the below error pop up on my ACC twice now. Then after about 30 minutes of driving and a couple of restarts it goes away. When I saw this on Christmas Morning while going snowboarding, I snapped a picture of it. Tomorrow I drop it off for service and I'll show them the pic.

I'm also not buying that it was cold and snowy outside when the pic was taken as the other time the ACC did this, it was 90 and I'd been using it on the freeway for hours...

Given there was a service bulletin to replace all 4 speed sensors for causing a similar warning, I wouldn't be surprised if it's the same thing. What year and model?
