The 2022 Jeep Gladiator belongs to the JT generation (pre-refresh) (2020-2023), built with 3.6L Pentastar V6, or 3.0L EcoDiesel V6 (2021-2023 only, automatic-only). It takes 0W-20 full synthetic on the Pentastar, 5W-40 full synthetic on the EcoDiesel. Oil changes run 10,000 miles (3.6L) / 8,000 miles (3.0L EcoDiesel). This is a late year of that generation, typically the most refined build after several years of running changes.
A 2022 Jeep Gladiator is 4 years old in 2026, which at an average 12,000 miles a year puts it around 48,000 miles - early ownership. Around 48,000 miles you are into cabin and engine air filters, brake fluid on a time basis, and the first brake pad inspections. Costs are still low, which makes this the cheapest period to stay ahead of the schedule rather than catch up on it. On that mileage estimate it should already have had engine air filter, cabin filter and a brake inspection at 30,000 miles, and the next milestone is 60,000 miles - transmission or CVT fluid, differential fluid and brake fluid - roughly 1 years away at average use.
The fault most worth knowing about on this generation is Death wobble, a steering oscillation traced to worn track bar and steering components, most complaints logged in 2020. Owners also report Manual-transmission clutch pressure plate overheating/fracture (fire risk) - recalled 2020, expanded 2021 and again in 2023; and EcoDiesel high-pressure fuel pump failures reported 2021-2023. None of these are certainties on any individual vehicle - they are the patterns worth checking for when you buy or when a symptom appears.

The table above is indexed by service interval. This is the same schedule indexed by odometer reading, for when you know your mileage and want the list. If your odometer sits between these figures, work back to the last one you passed and catch up anything skipped.
| Odometer | Service due |
|---|---|
| 30,000 mi (48,000 km) | Engine oil & filter change (0W-20 3.6L Pentastar), Rotate tires, Inspect brakes, steering, and suspension, Inspect ball joints and track bar, Replace engine air filter, Inspect drive belt, Inspect coolant condition and hoses. The every-8,000 mi service runs on its own cycle - the nearest fall at 24,000 and 32,000 miles. |

The every-8,000 mi service runs on its own cycle - the nearest fall at 56,000 and 64,000 miles. |
| 90,000 mi (145,000 km) | Same as the 30,000 mi service. The every-8,000 mi service runs on its own cycle - the nearest fall at 88,000 and 96,000 miles. |

Maintenance keeps these away, but when the dash does light up these are the codes this vehicle throws most often - each with what it means and what the repair actually costs.
