Just got a software update this week....

Just got an update and whole car is dead. Does not recognize key FOB. Its only been about 25 minutes since I chose "start update now"... How long do they usually take?

About an hour.

It's best to leave the car alone while updating. Don't sit in it. Click update, close the door, and come back in 90 minutes. You can also use the app to see if it connects. If it does, the update is likely done.

While unlikely, there have been cases in the past where an update did not install correctly because the owner was sitting in the car which interfered with the process.

Thanks. Will wait 90 minutes.

Most updates take much less time than 90 minutes, but the larger ones can take that long. There are a lot of devices on the bus within the car, and the updates are applied sequentially.

Didn't the screen tell you how long it will take? Usually it says more than an hour-- even when it doesn't take that long. It's really best to let the car install the update overnight. I think it defaults to 2 or 3 AM unless you've changed it. That way you aren't tempted to "check on it" which might screw up the installation, or cause you to panic when the car doesn't respond, and you'll be good to go in the morning.

It's a computer-- you wouldn't expect your Mac or PC to respond to anything while it's installing an operating system update.

UPDATE: Everything back to normal. The update took about 40 minutes. I left the car alone as you guys instructed and after about 40 minutes I go a pop up on my iPhone from the Tesla app that said update complete. Went out to the car and everything appears back to normal.

Oh right, I forgot it sends a notification now when complete. Even better.
