The Toyota 4Runner is among the most reliable models in our survey. My only concern is how old one will have to be to fall within your price range. Also, it's a large, heavy vehicle and doesn't handle well. Do you need a vehicle this large?
Unless you're planning to tow more than a small trailer or do some off-roading, I'd look for a better-handling, better-riding, more fuel-efficient car-based crossover. If you do need a fairly large vehicle, this would be the Toyota Highlander. But the smaller Toyota RAV4 might have plenty of space for you, and you could buy a newer one for $15k. I'd look at one of those first and only go larger if you determine that the RAV4 is too small. The only year for the RAV4 with iffy reliability is the 2006, first year of the third generation.
Honda's competitor to the RAV4 is the CR-V. It's also worth a look.
