2019 TRDOR here.
I want to start off with, I love my 4Runner. I'm a huge fan of the LC Prado, and wishing I could get it here. This is as close as I can get, unless I got the Lexus which I don't want.
However, I've found a few things I don't like.
My brakes rattle over bumps, it's a LOUD metal against metal noise. I've added grease, another anti rattle clip on the top AND had the dealership look at it and try their way which all failed.
The brakes are mushy, mushy, mushy - but I knew that going in. Not a *huge* deal, you get used to it. I am starting to kind of like it now, oddly enough.
The steering wheel gets a LOT of feedback from the road, from the engine vibrations and every pothole or uneven surface kicks the steering wheel pretty hard. I've always had rack and pinion steering, and my first car was hydraulic but my last pickup truck was electric and I guess I can feel the pump working in addition to everything else. It's a truck, so if you like feedback and not the numb feeling, you'll love this.
The biggest thing I HATE HATE HATE and makes me regret it every time I get on the highway is the steering input required. At 65 MPH+ I have to input steering to keep center lane or it drifts like nuts. It doesn't pull to one side or anything, I just have to keep moving the wheel a tiny bit left, right, left, right, left, right... It is tiring on my commute to work, and I HATE IT so much. I've NEVER had a vehicle track so poorly.
Last thing, and I don't know if it's doing it itself or if I am maybe bumping it on my way out of the vehicle... but the drivers seat back reclines on its own overnight. It's SO WEIRD. I am the only person who lives in my house, it is parked in my garage and my keys are by my bed and I know no one is going out there and messing with it. I'll get in and the dang seat is halfway reclined... like really?
I've listed some not so great, so let me list some great ones.
I love the height, for a mid size it's great. I love the look, very utilitarian. I love the 4wd lever in my TRDOR, I love my cloth seats very comfy. More than anything, though. I've come to love the fact that there are so many options for the 4Runner. It has so much possibility. You can make it whatever you want. The possibilities are endless.
Every vehicle is mechanical, you never know what issue you'll get. It's not a huge deal, though. It's a Toyota which means even clunking down the road, it'll get you from point A to B over any terrain, and in one piece and reliably.
Cheers
