Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the spark plugs every 100,000 mi; coolant at 150,000 mi. The big-interval services (at 150,000 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

The 2020 Jeep Gladiator marks the debut year of the generation, reflected in its relatively high complaint volume of 478—nearly double that of the 2021 model and over four times the 2022 count—while recalls (7) were slightly below the 8 seen in 2021 and 2022. Complaint trends reveal a steep decline in subsequent years, suggesting early production issues were progressively addressed, though the 2020 model’s top concerns (steering and electrical systems) align with common first-year teething problems. Recall activity remained consistent through 2022 before tapering, indicating systemic issues were likely resolved mid-cycle rather than isolated to the launch year. Crash and fire complaints (11 and 7, respectively) for 2020 are notable but not disproportionately high given the volume of other grievances. The data implies that while the 2020 Gladiator faced typical first-year challenges, later models benefited from corrective measures, making the 2020 a higher-risk choice unless thoroughly vetted for recall completions and updated TSBs. **Takeaway:** Proceed with caution—prioritize a pre-purchase inspection and full recall history verification, as this year sits at the peak of the reliability arc for the generation.
