Grade a specific Jeep Gladiator
Reliability changes from year to year. Pick a model year to see its grade, then add mileage and price to get a deal score and estimated miles remaining.
The Jeep Gladiator earns an F overall reliability grade from GradeMyCar, with a C- for its engine and a D for its transmission. It ranks 4th of 4 off-road SUVs we grade. The transmission (D) is the weaker of its two major components, so ask for transmission service records and pay close attention to shifting on a test drive. Grades are based on 951 owner complaints filed with NHTSA for the 2020-2023 model years, adjusted for how many were sold.
