Got the OTA update 2 weeks ago for my 2021, got home, parked and went about my day and has been fine no issues.

i'm sure almost all ota updates will go perfectly, but it's that small percentage that have a problem like anything
all it takes is a voltage drop during the process and wammo instant problem

Ran the OTA last night. First startup this morning was several seconds longer than usual and stumbled before smoothing out. Subsequent starts were a second or two longer than before, but seems to run OK.

‘22 Escalade- The OTA update did its thing and then wouldn’t recognize any key fob and every light was on. I had to disconnect the battery for 15 min and then everything was fine. It was like Kathrine fired up the microwave and it forgot it’s name!?!

I got the OTA update notification several weeks ago and started the update which looked like all was going well and left the vehicle. I came back later and saw this on the screen:

So I waited a day or so and tried again; same notification. I did this several times now... same-same. So I disconnected the battery for 10 minutes to see if a re-boot would work, no such luck, so it looks like a dealer trip in the future. Anyone else have this happen??
