Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2026 Gladiator.
The 2026 Jeep Gladiator pairs an eight-speed automatic transmission with EPA-estimated fuel economy of 17 mpg city, 22 mpg highway, and 19 mpg combined. Reliability metrics for this model year are sparse, reflecting just one owner complaint—centered on service brakes—and zero recalls across the board. Within the model’s documented history spanning 2020 through 2026, a period that opened with 478 complaints in its first year, the 2026 model stands at the opposite extreme with the fewest reported issues, indicating a significant reduction in documented defects relative to earlier production.

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
Across the Gladiator's generation, federal complaint volume has fallen dramatically and consistently — from 478 in the 2020 launch year to just 1 in the 2026 target year — while recalls have similarly tapered from a peak of 8 (2021–2022) down to zero, and investigations have been absent since 2023. TSBs have followed the same downward arc, dropping from 693 in 2021 to 90 for 2026, suggesting Jeep has progressively resolved manufacturing and design issues identified earlier in the cycle. The 2026 model year sits at the mature tail end of this trajectory, which is generally where you want to be in a vehicle generation: most early-production bugs have been addressed, and the recall and investigation pipeline is clean. However, the single recorded complaint — in Service Brakes — and the near-zero counts across all categories should be read with the caveat that a 2026 model has had minimal time in consumer hands, so these figures will likely grow as more units accumulate mileage. The data does not specify a root cause for the brake complaint. The concrete takeaway: the 2026 Gladiator appears to be the most refined product of this generation on paper, and the established downward trend in complaints and recalls makes it a strong candidate — but buyers should verify that any open recalls from prior years have been completed on the specific unit and monitor brake performance closely given the lone recorded complaint area.
