2021 RAV4 Prime XSE
I have a non-premium US-spec XSE - so, I just discovered something today - there is a certain road nearby, with a certain hill that, when I'm going 50 mph (cruise enabled - I'm not sure what other speeds it may do it at but I go 50 on that road), the ICE will turn on every time I go down that specific hill. I have been able to reproduce it 3 times in a row various times over the last 48 hours. Each time I was in EV mode and had between 10-20 miles of EV range. I have about 1/2 tank of gas, which I got about a week ago, so the majority of gas in the tank is new/fresh. I, like many, have noticed the ICE kick on a seemingly random times when in EV mode, but this is the first I've been able to consistently reproduce it. Any ideas? Are those particular conditions just matching Toyota's "turn the ICE on" criteria? Anyone else been able to REPEATABLY have the ICE come on (other than by things like pressing the front defrost button or when the battery is full and there is enough regen to kick it on)?
