The biggest downside of a plugin hybrid is the complexity and therefore higher service costs, likely shorter lifetime etc. You have all the maintenance requirements of a regular ICE vehicle and an electric motor + battery on top of that. Also the full electric range is likely much lower than an electric only vehicle so running costs would be higher. Some EVs have full charge range that's not much less than a full tank of gas on an ICE at this point - the range is really a non issue for a lot of people. I drive an EV with a comparably low range (~130 miles) and I can still count on one hand the number of times I've needed to drive further than that in one trip - on those occasions other than my lunch/dinner stop being limited to places with a charging station nothing really changed compared to when I drove an ICE. The rest of the time I get to plug it in in my garage overnight instead of having to stop at petrol stations, which is a nice albeit minor convenience increase.
