Schedule your updates for late evening. Drive the car just before then. Plug it in to charge.

Low 12V can often be the cause of a failed update. My PaaK update failed a couple of times.
I’ve tried that and it’s failed 3 nights in a row. I even disconnected and reconnected the 12v to ensure a tight connection. This update is really struggling to load on my truck. Any other ideas?

I just received notification of 3.5.5, (started rolling out yesterday), but my truck is having issue installing it. It has failed 3 times. I'm wondering if it is a battery voltage issue. It is cold here (at least for TX standards). This update will keep me up to date on everything except PAAK also. Don't know when they will think I'm worthy of that one.
This is happening to me, also. Can't get the update installed!

I tried manually and via scheduled updates three days in a row. Plugged in and connected to WiFi in the garage. The update kept failing. Then today I tried to manually update after parking at work and it uploaded via cellular. I tried driving the block a few times as Coral suggested to ensure the 12v was at a high charge. Not sure if the success was because of a longer commute, cellular instead of WiFi, or just dumb luck.

My vote is because of cellular coverage. WiFi updates seem to be a myth at this point.
