On my second Highlander, the first one is owned by a family friend and is not being well cared for, however it is still going strong. My latest model is a '19 and I have not had one issue with it, no recalls that I can remember. I think they are the best SUV on the market, the only thing mine have never delivered is mileage. In town I don't think the first one ever got better than 17, this one did the same until it finally broke in at around 15K, it gets 18 now. I did not opt for Hybrid drive in either Highlander. My wife's little Camry is a Hybrid, fifteen years old and no problems other than replacing the starting battery twice, another amazing little vehicle. She can have anything she wants and has no interest in replacing it with anything, to me that speaks volumes about being satisfied.
I see where Toyota is doing a ton of research into hydrogen fuel cells rather than EV, we'll have to see how this works out.
