What Isuzu's New Zealand booklet asks
The standard warranty runs three years from the day the ute was first registered new in New Zealand, or 100,000 km, whichever comes first, and roadside assistance lasts as long. It only applies to utes retailed, registered and operated here. Check your own papers as well, in case your ute came with extra cover.
Most of what the booklet won't pay for comes down to upkeep: damage from missed maintenance or the wrong fuel, oil or lubricants, improper maintenance by someone other than an authorised dealer, modifications Isuzu hasn't approved, and an odometer that has stopped or been tampered with. It recommends keeping receipts for the regular maintenance, and that's worth doing.
The first check comes early, at 3,000 km or three months. After that, the schedule runs by distance or time, whichever is reached first.
What a working ute needs from its mechanic
A D-Max that tows a trailer, carries a full tray or lives on gravel roads works its brakes, suspension, tyres and driveline oils far harder than an MU-X doing the school run. Tell the mechanic how it's used, so the checks match the work.
Running a diesel here means keeping road user charges current, and AA New Zealand notes that modern diesels carry a particulate filter. If yours also uses diesel exhaust fluid, act on the first warning, because the engine won't start once the tank is empty.
Canopies, bull bars, towbars and lift kits are common on utes. The booklet excludes modifications Isuzu hasn't authorised, so mention anything that's been fitted.
What a D-Max or MU-X service should include
- The service Isuzu's schedule lists for the kilometres or months, by name.
- Engine oil and filter to the grade the handbook gives.
- The fuel filter, when the schedule says it's due.
- Brakes, steering joints, suspension and tyres, checked with the ute's workload in mind.
- A receipt showing the date, kilometres and parts, for your records.
Questions for an Isuzu mechanic
- Do you service D-Maxes and other diesel utes most weeks?
- Will you follow Isuzu's schedule and put the details on the receipt?
- Can you check the particulate filter and read the ute's fault codes?
- Can the work fit around the days the ute is needed on the job?
Your side of running an Isuzu
You can

- Set tyre pressures for the load, using the placard on the door pillar.
- Keep the road user charges licence up to date.
Leave to the mechanic
- The scheduled service and filter changes.
- Fuel system, injector and particulate filter faults.
- Brake and suspension work on a ute that tows.
What we'd do with an Isuzu
We'd work out when the ute will reach 100,000 km, because on a busy ute that ends the warranty well before the three years do. Then we'd use a local garage that services diesel utes every week, keep every receipt, and tell them about the towing and anything bolted on. A local mechanic who specialises in your car.
