I had to rent a vehicle and leave the truck behind.
Bring a ODB reader and clear the error. You can then DC charge normally below 80% and AC below 90%. Above this, charging may slow more than usual as the truck protects itself against overcharging the out of family errant voltage cell. If you don’t have an ODB reader, stop by an auto parts store and they’ll let you borrow one in the parking lot for free.

The cleared error will return in a few days, depending on temperature, pushing the cell out of voltage for enough time. So, get it addressed when convenient. (The dash message says service vehicle “soon”)

@pmac1010 Please provide Year, model, ER/SR, and build date for the tracking sheet (in my signature). Not sure if the number of battery module failures are stabilizing yet.
