I actually do want a RAV4, but since it's so new it's a bit too expensive for me at the moment. My only hope of getting one would be a few years down the road, when I can buy one used. However, I don't think I'd want the 2019 model, it needs some refinement and fixes/updates honestly.
I hear it's loud, a lot of engine noise, not insulted well, I want to see improvement on quietness, sound deadening.
I also think that many of its features needs to be standard features at the high-end trim level. Things like the heated/cooled seats you can't even get unless you get a certain package upgrade. Heated seats should be a standard feature at the top-end these days for crying out loud. There's too many features currently wrapped up in packages and not part of the standard trim features. They need to bundle more of the packaged items into the top-end trim and Adventure trim as standard. Right now you have to purchase like 4-5 extra packages on top of the top-end trim to get everything, and that's just ridiculous.
It needs some fixing/editing of the AWD system in regards to sending more power to the back wheels more often. I've seen a lot of people do a lot of tests, and it is very FWD biased, even though it can send 50% of power to the rear wheels, it usually opts not to, it needs some tweaking there.
I'd like to see further refinement of the interior materials.
Fix those main issues for me, and maybe in several years I'll get one. Maybe a 2021 or 2022 model, when the kinks are worked out.
