Check your own book against that table
Those are the figures in CarsGuide's August 2022 table, and they cover the cars it listed at the time. Your service book is the final word, because a Wrangler can also have a diesel, and that's not in the table.
If you tow or spend time on dirt and sand, ask the mechanic whether your book lists shorter gaps for harder use.
Five years or 100,000 km: what the Jeep warranty means
Jeep's factory warranty is 5 years or 100,000 km, whichever comes first. Drive more than 20,000 km a year and the kilometres will finish it before the five years do, so note that if you use the car for work or long trips.
Roadside assistance runs for the length of the warranty on every new Jeep. A capped maximum price applies to the first five scheduled services on new vehicles sold after 1 July 2026.
Servicing by a qualified independent mechanic, done to Jeep's schedule and specifications, doesn't by itself void your warranty. Warranty repairs are handled by Jeep dealerships and Mopar Service Centres.
The small electric Avenger has a condition worth knowing. Its 8 years or 160,000 km high-voltage battery cover lapses if the scheduled servicing, including the battery check, isn't done at the frequencies in its Owner Handbook Supplement.
Why a Wrangler isn't like other 4WDs on the hoist
A Wrangler keeps a separate chassis and solid axles (a single beam joining the wheels on each end), where most SUVs have independent suspension. That's why it's good off-road, and it's why the steering and suspension need someone who understands the layout.
Lift kits, bigger tyres and bull bars are common, and each one changes how the steering and brakes behave. Tell the mechanic what's been fitted, because an alignment on a lifted Wrangler isn't the same job as one on a stock car.
A Grand Cherokee is a different animal: a family SUV with a lot of electronics. A workshop that does both is worth finding.
What to ask a Jeep mechanic
- Do you see Wranglers and Grand Cherokees regularly?
- Which schedule are you working from, and does my use change it?
- Can you read Jeep's own fault codes on this model?
- If it's been lifted, how will that change the alignment and the steering checks?
- Which oils will go in the engine, gearbox, diffs and transfer case?
What's safe to do on your Jeep
You can
- Keep a note of everything fitted since new, with dates.
- Check the oil and tyre pressures cold, and set pressures to suit your tyres and load.
- After mud or beach trips, rinse the underside from beside the car.
Leave to the mechanic
- Steering and suspension checks on lifted cars.
- Diff and transfer case oils, particularly after water crossings.
- Reading fault codes and electrical work.
What we'd do with a Jeep
We'd start by checking which interval the car's on, because 12,000 km comes up fast. We'd give the mechanic a list of every modification, and ask for a written estimate that names the oils and marks anything that can wait. Then we'd choose someone who has a Wrangler on the hoist most weeks. Tell us the model and what's been fitted. A local mechanic who specialises in your car.
