i charged o/n w 110v charger to auto charge stop. Next day left home (1006 on odo) on EV/Econ and within a quarter mile the ICE came on at low rpms. Stopped car, turned off within less than 4 min, and on restart could reenter EV/Econ mode and drive off with usual behavior for rest of day. I noticed that info screen showed at one point ICE was charging HV battery (foot off accelerator), and power meter was all hashed white not blue. Also noticed loss of 2 miles on HV range. Here’s what I don’t understand: -I don’t think it was because regen had to have ICE operation because HV battery was full since there are no hills involved and I was driving sedately. -and I don’t think it was Service Mode since the ICE had started on its own just 7 days/168 miles beforehand with no reason to that I could tell. However both times happened very close to home when leaving with a full charge. But that’s just like I’ve done every day for for 6 weeks without this happening. So any ideas on what’s going on?
