Anyone have intermittent power loss to front motor?

[WaterboyNorCal]

Twice now in the past two weeks, my “available power” gauge has gone from 95-100% immediately down to somewhere between 64-65%, and the “power distribution” graphic indicates that the front motor is neither receiving power, nor is any regen braking occurring. The rear motor appears to be operating normally. I have received zero error messages, and the truck FEELS pretty much as usual, though isn’t accelerating quite as quickly. I’ve seen this happen at ~85% SOC and today at 33% SOC. When it happened today, I pulled over when it was safe and powered down the truck, waited 30 seconds, and then restarted. The available power started at 95% and almost immediately dropped to 64%, and the graphic indicated that I was getting no power to the front motor, though regen braking in 1-pedal mode felt pretty normal. After parking the car again, this time for ~15min, I was back to 95% available power and the front motor, according to the Power Distribution graphic, was behaving normally. I drove home (about 6 miles, took 15 minutes), and everything was normal, as if the previous episode had never happened.

Anyone have any experience with something similar? It’s weird behavior, and concerning because I have never seen this before, and I have over 31,000 miles driven over 14 months of owning this truck. Is it possible this is a software glitch, and I am not really losing the front motor? I would hate to lose AWD in the snow…

I have had it happen once so far in 40K km. Yes it was a snow day and the loss of traction was very noticeable. I haven't seen any remedies posted other than what we both tried - 1) wait, 2) restart a few times. Highly technical troubleshooting approach.

I had this happen right after a non-inhibit update had processed on my truck, just as you did I got to my destination fine as it was a short drive, and shut down, then let it sit for a couple minutes, afterward, all was fine, no problems since.

Yes, three times in 46,000 miles. Each time I pulled over. I had to do more than just turn off truck off and on. What I found works is pull off road, turn off truck, get out, lock truck then unlock, get in and start up truck. If I left out any of these it would not return to both motors. Doing all the last two times worked.
