Does AWD stop working with reduced power output/range?

This is the third winter I've had my lightning in the UP of michigan. We get a lot of snow, and I've never had an issue.

I was driving down a driveway that isn't maintained well. I would estimate 4-6 inches deep of snow with icy snow pack bottom. (no sand or salt) Usually the truck just drives fine through that though.

Turning around the rear tires were in slightly deeper snow and I got temporarily stuck. I also barely made i back down the driveway, and barely made it up the ever so slight incline out on to the road. Even when front tires were on asphalt, the rears just spun.

For the first time I enabled the off road rear locking differential, which may have helped a tiny bit but rear kept spinning out still.

I had to do many many attempts rocking back and forth and it probably took 10 minutes to make it out of the driveway.

It only used the rear wheels. I kept spinning out no matter how hard I tried.

It was kind of cold, and didn't have much range. I think the left power output dial gauge was at high 30s or 42 percent max output?

There were no notifications or alerts or errors, other when the limited traction light came on.

Does power stop going to the front in limited range or something?

There is a power distribution display on the IPC, take a look at that to confirm that the front motor might not be putting out traction energy.

Usually the limited power to motors on the left side of gauge relates to software controlled limits because of cold conditions and low HVB SOC, not that it's shut down the motor all together, but we have seen such conditions when the truck is throwing a reduced power error code.
