I have a 5th gen 4Runner, it's a 2013 with 165k on it. I've owned it since 79k, which has been almost 5 years. It's been super reliable in that time, other than routine maintenance the only thing I've had to do is have the AC topped off two years ago. The 4runner is probably going to be more reliable, but the Jeep is going to drive way better, and have way more power if you get the V8. 4Runner doesn't drive that great, and it's underpowered.
