I have read the term "Angry Bees" for months but I had never experienced it, until last night. Christmas Eve I went to a relative's house, 18 miles from my house. Had 36 mile of EV and had used 18 miles of EV when I got to my relative's house. The EV range showed I still had 18 miles. Later that night, I went home but I did not take note of the EV range. It was cold, about 36 degrees. About 8 miles from home the engine started a high rate of RPMs, really high. I let up off the accelerator and it RPMs were still high. During this time I noticed the EV range was zero. I tried all the different mode on the way home, the RPMs were still high. I have owned my Clarity since March 15th, first time this has happened. So, for people who have experienced "angry bees", did it happen when your EV range was zero and before you selected the HV mode? Any explanation for the excessive RPMs? It seems the car would have accelerated with those high RPMs?
