Unfortunately, you might not have any acceptable alternatives. The Toyota 4Runner, though very reliable, is V6-only and doesn't handle or ride nearly as well as the Jeep. The Nissan Pathfinder was available with a V8 through 2012, but I'm unsure of its reliability, since we have no data on its more recent years. Earlier model years were iffy. Other alternatives are European, and they tend to be riskier than the Jeep.
Basically, people seeking a recent midsize true SUV must choose between the Grand Cherokee and the 4Runner. The Toyota is reliable and performs well off-road. The Jeep is offered with more power and rides and handles much better on-road.
