Which Cannon have you got?
This ute went on sale here as the GWM Ute, in Cannon, Cannon-L and Cannon-X dual-cabs, with a 2.0-litre turbo-diesel. It became simply the GWM Cannon in a 2025 facelift that added the 2.4-litre turbo-diesel. The Cannon Alpha is a separate model, so check the badge.

What those services include
Those points come from GWM's service sheet, and whichever comes first counts. It covers the first five services. Past those, ask the mechanic to follow the book.
Timing belt. This is the toothed belt that keeps the engine's valves in step with its pistons. On the 2.0-litre, it's first replaced at 75,000 km, then every 80,000 km. On the 2.4-litre, it's first at 70,000 km, then every 75,000 km. Put that kilometre reading in your phone now.
Diff and transfer case oils. On the 2.0-litre, first due at 45,000 km. On the 2.4-litre, first due at 40,000 km or 36 months.
EGR valve. The sheet has the 2.0-litre's EGR valve (it feeds some exhaust gas back through the engine) inspected at the 18-month service and every second service after that. On the 2.4-litre, GWM lists a shorter cleaning interval for severe duty.
2.4-litre owners with an old reminder. GWM announced the longer first service on 19 June 2025, and said some owners might still get a 5,000 km reminder from the original book. GWM announced no change for the 2.0-litre.
Towing, dirt roads and heavy loads can count as severe duty, and GWM says that can shorten some items. Tell the mechanic what your ute does in a normal week.
Common GWM Cannon problems
Fuel filter O-ring recall. CarExpert reported 2,872 Cannons built in 2023 recalled, because the wrong lubricant on the diesel fuel filter's seal can degrade it and let fuel leak, with a fire risk.
Cannon Alpha steering recall. 2,458 Alphas built 2023 to 2025 were recalled because the power steering wiring harness can rub on the driveshaft. If you lose steering assist or the engine cuts out, pull over somewhere safe, stop driving and have it towed.
Short trips in a diesel. CarsGuide warned that a diesel particulate filter (DPF, which traps soot) can clog on a ute that only does short runs. See the DPF warning light.
Brakes that don't let go. A 2021 owner reported front brakes that applied and wouldn't release. CarsGuide called it potentially lethal and said to stop driving and have it towed. Any brake problem is the same: pull over somewhere safe, then get it looked at.
Warranty
carsales lists seven years and unlimited kilometres on the 2022 ute. If a qualified independent mechanic services your Cannon to GWM's schedule and specifications, that does not by itself void the new car warranty. Service it on time, and keep invoices that name the oils and parts.

Our take on the Cannon
Don't rely on the dash reminder or a general rule for utes. Open the book, find your engine, and write down the next service and the timing belt reading. Check the VIN on vehiclerecalls.gov.au for the fuel filter recall. When you ask for an estimate on a timing belt, ask for the tensioner and pulleys to be listed too.
