Was driving the car earlier today. I had just gotten home and parked with the usual 75-80% charge in the SOC gauge. 10 minutes later I back out. I backed out, then was cruising down the street for no more than 200 meters at an easy 15mph. The ICE then kicked in as there was a hill up ahead. Next thing I knew, I felt a slight give in the gas pedal, heard and felt the engine rev up. I glanced at the dash and noticed that the SOC had all of a sudden dropped to 2 bars, all within a span of less than a minute. This has never happened before. I understand that the EV can significantly deplete the hybrid battery, but never this severely and quickly. The opposite had happened about 10 months ago, when the ICE hyper-revved to over 3k RPM while I was going no more than 25MPH, but the SOC never dropped. There was a posting of something similar in a Gen 2 a few years ago but I wasn't able to find this occurring in another Gen 3 user. Any clues would be greatly appreciated.
