Overview

2018 Jeep Grand Cherokee

The 2018 Jeep Grand Cherokee, particularly in its higher trims, presents a compelling package of power and off-road capability. This model year boasts a strong V8 engine option and a robust 4WD system. However, a significant number of Technical Service Bulletins (TSBs) suggest potential for various minor issues that, while not safety recalls, can impact long-term ownership satisfaction. Its safety ratings are generally good, with excellent scores in side impact protection.

Critical Failure Risk

Early detection can help you avoid a $500-$1,500 repair.
