The Jeep brand embodies the essence of rugged, go-anywhere vehicles. Jeeps have a long history of customer loyalty despite lagging in reliability, fuel economy, comfort, and interior fit and finish. Nowhere has that been truer than with the rough-rider Wrangler, an iconic workhorse loved by its owners. The latest Wrangler (JL) touts many improvements over the previous model, and a Gladiator pickup truck version should broaden the model’s appeal. The Grand Cherokee is, by far, the Jeep with the highest road test score. Reliability is a concern across the brand.
