Yeah, we can't seem to kill our battery either.So this same issue has been happening since 2017? Are they still using the same part?
Ours just failed at 13k on our 2021, within the first few weeks of regularly cold weather.
I understand this is safe to drive, but ours is at 100% battery, and even driving 40+ miles yesterday, it never allowed us to use more than ~10% charge on electric. Then the ICE comes back on and recharges it. We live in a hilly area and it drives terribly in this mode at 100% - the ICE keeps cycling on and off every few seconds. Any ideas how to discharge the battery?
