R1S Motors Heat Up During Charging on RAN

Last night, when I reached my Rivian truck after work, my iPhone displayed a message. I captured a screenshot to show what happens if you avoid signing back into the app. The Phone as a Key (PAAK) feature still works without logging in again. If you're in an area with poor cell service, don’t try to sign in. Instead, keep using the app and PAAK until you’re somewhere with a good signal and can access your password. The screen’s text explains this, but some users still get confused. This is a quick tip for PAAK users to avoid trouble.

Has anyone ever had an issue while charging on RAN the motors heat up?

RAN Charger 2B
Right front 100 degrees
Left front 70 degrees
Both rear motors 80 degrees

As soon as I stopped charging the motors started cooling down, battery temp was 89 degrees. Right front turned orange. I only added 20kw to the battery in about 13 mins. Stopping the charge removing the connector and starting a new charge didn't replicate the same issue.

Someone told me it’s normal. That the motors are used to warm the battery to optimum charging temperature. I just want to hope that they're right and if so, that means I still have some Rivian learning to do.
