The Prime has been great. Handles better than the 13 year old sedan it replaced, it has a compliant ride, it's super functional, it's spacious enough for road tripping and car camping with four adults, it has enough ground clearance (8.3") to tackle a curb, a mildly rocky road, or some snow when necessary, and of course it's crazy efficient. I got the XSE with the premium package, too, so it's got enough extra features to help the car at least take a swing at its Lexus-like price.
The 42 EV miles per charge that it's rated for has been spot on, but usually as a floor, not a ceiling. I'm often getting 50+ miles of range if I'm driving only city miles. Pretty solid for about $1.30 worth of electricity. The estimated 35 - 40 mpg on gas alone is accurate, too, though almost all of my gas-only miles have come in highway driving on road trips.
My complaints are minor. I drive with the seat most of the way back (I'm 6' 4") and the wide B pillars are a little obstructive of my line of sight over my shoulder. There's more road noise at highway speeds than I'd like. Toyota's media interface on my '21 model -- which I bypass with Android Auto -- is dated. And . . . that's about it.
You can make reasonable arguments for and against the car based on it's value proposition vs regular hybrid SUVs. But you just need to know those pros and cons going in. Bottom line, it does everything it's supposed to and does them incredibly well
The cable issue you've heard of affected all (or many) hybrid RAV4s, plugin or not, early-ish in the current generation. I believe that Toyota addressed the issue starting in 2021 or 2022. Regardless, they've offered a specific eight-year, 100,000 mile warranty for the affected cars. I got a letter about it last summer.
Here are some details about it. I've not heard anything about more recent model years behind affected.
Feel free to message me if you'd like me to nerd out with even more details.
