Having the same issue all of you are experiencing on a 2018 Honda Pilot Elite - currently at 22k miles. It first appeared about a month or two ago with all the alarms flashing on the dash and cleared itself after a couple hours of shutting off. I thought that was the end of it. It’s Memorial week 2020 and I had it twice in three days now. It started after I stopped at a red light and started to make a left turn, that’s when the car stuttered for a bit and every alarm came on. Acceleration was hard and steering the wheel was slightly harder. RPM and the speedometer is at 0 when I’m driving with all the alarms flashing. I will see if I can get my car in for service today as it should still be under warranty and I got the Honda maintenance package too. Hopefully they have an update to this issue by now.

Update from Jun 9, 2020: Week 3 of having my car in the shop. They haven’t figured it out yet. Last week they told me to get my car and see if the issue comes back. After 10-15 minutes of driving, it came back. I took it in the next day and now it’s week 3. My car is still under warranty so Lemon Law will need to be enforce if they can’t fix it.
