Known problems
- Worth watching
Diesel DPF / EGR clogging in short-trip use
Symptoms: loss of power, warning lights and more frequent regeneration cycles on the turbodiesel when the truck is used mostly for short, low-speed urban trips; over time the EGR and diesel particulate filter can soot up
What to do: Give the diesel regular longer runs at highway speed so the DPF can complete its regeneration, use good-quality diesel and the correct low-ash oil, and keep the fuel filter fresh. If a regeneration warning appears, drive as instructed rather than ignoring it; have the DPF/EGR checked if power stays down.
- Good to know
Cold-weather electronics and transmission warnings
Symptoms: in hard frost (around -20 C and below) some owners see transmission or system warning messages until the drivetrain warms up; behaviour normalises once up to temperature
What to do: Let the truck warm through before demanding full load in severe cold, and note that these messages usually clear on their own. Have it checked only if a fault light stays on after warm-up.
- Good to know
Touchscreen-heavy controls and infotainment quirks
Symptoms: climate and most functions run through the central touchscreen with few physical buttons, which is awkward on the move; owners also report occasional head-unit lag or freezes and some rough Russian menu translations
What to do: Keep the head-unit software updated at the dealer, and note the exact conditions that trigger any freeze so service can reproduce and reflash it. Treat the button-light layout as an ergonomics trait of the truck.
Service schedule
| Item | Interval | Notes |
|---|---|---|
| Engine oil & filter change | every 6,000 mi (10,000 km) or 12 months | GWM specifies roughly 10,000 km; the 2.0T petrol can stretch toward 15k, but many owners shorten to ~7,500 km for short-trip, dusty or towing use, especially on the turbodiesel |
| Cabin filter | every 9,000 mi (15,000 km) | — |
| Fuel filter (diesel Common Rail) important | every 9,000 mi (15,000 km) | diesel only — the Common Rail system is fuel-quality sensitive; drain any water separator regularly. A DPF is fitted, so give the diesel periodic longer highway runs to let it regenerate |
| Air filter | every 19,000 mi (30,000 km) | — |
| 8-speed automatic (ZF 8HP) fluid important | every 37,000 mi (60,000 km) | not a lifetime fill for a heavy pickup that tows — change the fluid around 60k km |
| Timing drive service critical | every 56,000 mi (90,000 km) | the 2.0 diesel (GW4D20M) is timing-BELT driven — replace the belt on schedule (many mechanics do it preventively earlier) because a snapped belt can cause serious engine damage. The 2.0T petrol (GW4C20B) is chain-driven — inspect for noise rather than scheduled replacement, and change its spark plugs around 40k km |
| Brake fluid important | every 36 months | — |
Manufacturer-declared fuel economy
No manufacturer-declared figures for this model are in the Knowledge Base yet. A figure without the cycle it was measured under is not comparable to anything, so we publish none rather than a number you cannot interpret.
