Kyle’s Clarity

I did a cursory search but didn’t see anything that sounded quite like what I started experiencing recently.
I’m about 2-2.5 months into ownership of my ‘19 Clarity and over the past week or so my ICE has engaged at times that don’t seem to line up with any need. It hadn’t been so long since the last time it was on that it would need to run a systems check and I didn’t white-line it. This leaves energy bleed-off on a full-battery and, while this has been a likely explanation on a few occasions, there have been multiple instances where the SoC is 1-3 bars below full and it still engages. Sometimes it’ll engage while braking and sometimes while accelerating.
If I had to made an uneducated guess I would say it seems like the computer is confused. The pattern I’m seeing is that the ICE is engaging (somewhat eagerly I’d argue) to bleed off regen power shortly after starting city driving on a full charge. Like if I hit 2 or 3 red lights, it’ll kick in while braking. It feels a lot more sensitive to this than it’s ever been. The issue beyond this though is that it’ll continue to engage the ICE repeatedly for the remainder of whatever drive I’m doing (regardless of mode) sometimes while braking, sometimes while accelerating, and in many cases for extremely brief periods of time (if I’m trusting the EV indicator on my cluster, for as little as a few seconds sometimes). It almost seems to be behaving like it’s in HV Mode except it’s showing a white power gauge the whole time (whether the EV indicator is on or not it doesn’t seem to change when it’s behaving like this). I’ve heard of and witnessed the power gauge colour issue in other circumstances too so this could be unrelated.
