The 2024 Jeep Gladiator belongs to the JT generation (refreshed) (2024-present), built with 3.6L Pentastar V6 only. It takes 0W-20 full synthetic. Oil changes run 10,000 miles. This is the first model year of that generation, so it is the build most likely to carry early-production quirks and the most likely to have accumulated technical service bulletins.
A 2024 Jeep Gladiator is 2 years old in 2026, which at an average 12,000 miles a year puts it around 24,000 miles - early ownership. Around 24,000 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 the next milestone is 30,000 miles - engine air filter, cabin filter and a brake inspection - roughly 1 years away at average use.
The fault most worth knowing about on this generation is 3.6L Pentastar oil-filter-housing leaks (a long-running issue on this engine family). Owners also report Death wobble remains a solid-front-axle possibility across the refresh; and Electric power-steering pump connector overheating/fire risk (recall 26V363000, issued 2026-06, covers trucks built through December 2, 2024). 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.

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.
