Has the car ben standing still for a long time..?
It is most likely a case of one or to modules going bad as described by Harleyguy (he is very knowledgeable).
But don't despair (yet), try this for a repairÖ It can also be a case of battery module (there are 15 modules in you HV battery pack) or cell in battery module being out of balance due to deep discharging. Try to cycle the battery pack a few times by driving it down to zero (not red!) on the battery meter and recharge to full (let it charge undisturbed).
