1--the "big" battery that runs the whole thing doesn't get replaced affordably. The "little" battery--a standard 12v--is replaced just like in an ICE car. From what I've learned, the 12v going bad is what creates most problems reported by EV drivers--easily fixed. Maybe they run out faster than in ICE car? I haven't had that problem myself.
2. It gets hot here, too. And cold in the winter. From what I've seen, both reduce the range by about 30%, so instead of getting 85-100 miles on a charge, it is reduced. Not a problem if you don't drive long distances.
3. It is fantastic doing hills--I can't believe how zippy it is! And on the other side of the hill, the brakes are regenerative.
4. I wish I could answer that--we went from two cars, with a teenage driver in the house, to one car, and then got the the LEAF. I don't think it went up significantly from when we had the Prius and a Subaru before our teenager started driving.
5. The LEAF is the most fun car I've ever driven. We've had the Prius for 10 years and it has been very reliable and pretty zippy itself. If you need more range, I'm a Prius fan (but haven't researched the other hybrids). The LEAF is more comfortable. I really am crazy about the LEAF. Also, the used LEAFs are so darn cheap!
I think it comes down to range. We use the Prius for longer trips, and if we needed a different car for some kind of trip, or the Prius dies, we would rent a car.
I have found Reddit a valuable source of info--and lots of people who are considering buying ask questions and get answers from very experienced drivers. There's an R/Leaf group and an R/Electric Vehicles--both helpful.
Also, if you are considering, everyone will tell you to get LEAFspy app and a little thing that plugs in to check battery health. Lots of deets about that on Reddit.
Have fun looking!
