Here's a list of qualifying vehicles:
The 4Runner is the clear winner in reliability. Very few vehicles hold up as well. You've driven the Limited? A good friend just bought one.
Among the others, the Flex has been pretty reliable from 2011 on in our stats. If this is a vehicle you'll only have for three years or so, it should be fine. Drives BIG, though. As does the Explorer, but in a different way. We own a 2008 Ford Taurus X, which shares some components with both. At nearly seven years of age various bits are clearly less than robust.
The Grand Cherokee is probably the best fit, except for reliability concerns. Note that even with the Jeep your odds of no repair in a given year aren't bad (we have odds stats for the 2011 and 2012). How long are you likely to keep it?
