The Jeep brand embodies the essence of rugged, go-anywhere vehicles. Jeeps have a long history of customer loyalty despite lagging in fuel economy, comfort, and interior fit and finish. Nowhere has that been truer than with the roughrider Wrangler, an iconic workhorse loved by its owners. The Gladiator pickup truck version broadens the model’s appeal even more. The Grand Cherokee is, by far, the Jeep with the highest road test score thanks to its accomplished ride, handling, seat comfort and easy controls. Reliability is a mixed bag across the brand.
