OTA Update on 2021 Yukon Denali seems to have bricked my truck

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

Same but I always hold my breath when I complete the first start after the update.

Same here except it was just yesterday. It took maybe 4 minutes to complete and I’ve noticed zero change with anything

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

My OTA update/d yesterday. NO issues and nothing seems to have changed....

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.

who knows if the OTA was the issue, could have been a bad battery from the start

‘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??

This is why I keep and drive my "old" trucks

1. 1991 Suburban 4x4
2. 1988 Suburban 4x4
3. 1988 V-Jimmy
4. 1986 C2500
5. 1983 C2500 Crew Cab

All the updates they need is fresh gas and oil.
