No experience on the 2024 Model, I have a 2018 and it's been superb. Had some recall fuel pump change. done for free by the dealer and I've changed battery, getting close to.needing a new one. It's not uncommon for batteries to only last 3yrs in Houston.

The radio died, and it's the only thing I believe may be a common problem issue.
My next car would be another Highlander, hybrid this time, or a Tundra. However the 2018 Highlander still has a LOT of life left.
A friend has a hybrid Rav4 and only has praise for it
if the 2024 is anything on par for Toyota, it should be a great drive.
