I never said electric only. I mean coasting with engine running and IMA not charging (no bars) with foot off the gas pedal.

ICE is always running unless you shut it down. The car can coast (no foot on the gas) without the IMA recharging. ICE shuts down cylinders when coasting to maximize regenerating IMA but it is possible to coast without charging. This happens for me when traveling between 25-40 miles per hour and I remove my foot off the gas slowly (I can't be going down a hill when doing this or it regenerates). Most times I have to give a quick pulse of gas to trip it to regenerate for me when I want to slow my speed (when I don't want to use the brakes). I think it relates to the way I drive my car.

I can't imagine why this never happened for you. Unless you remove your foot quickly every time, it should be able to coast.
