Known problems
- Worth watching
Infotainment freezes; risky DIY firmware 'russification'
Symptoms: the stock head unit can lag or freeze; on Chinese-spec units, do-it-yourself Russian-localization firmware carries a high risk of bricking the unit, and a botched flash or power loss mid-update can require a costly head-unit replacement
What to do: Buy the officially localized Russian version; never DIY-flash the head unit or cut power mid-update, and use a reputable installer if localization is needed.
- Good to know
Transmission kick when pulling away (early cars)
Symptoms: a shift 'clunk' or kick when moving off after a stop on early-build cars
What to do: Confirm the updated engine/transmission software is installed (GWM issued an update in autumn 2024 addressing this) and test-drive a used early car for the kick.
- Good to know
Winter cabin/climate quirks
Symptoms: below about -10 C the climate system can default to recirculation and fog the windows until switched off manually; some owners note a cold draught around the driver's right knee/tunnel area
What to do: Manually switch off air recirculation in hard frost to clear fogging; treat as a minor comfort trait, not a fault.
Service schedule
| Item | Interval | Notes |
|---|---|---|
| Cabin filter | every 9,000 mi (15,000 km) | — |
| Engine oil & filter change | every 9,000 mi (15,000 km) or 12 months | factory ~15k km; use API SP 5W-30. Turbo owners often shorten to ~10k km in city/harsh use |
| Air filter | every 19,000 mi (30,000 km) | — |
| Spark plugs | every 25,000 mi (40,000 km) | turbo direct injection |
| 8AT (ZF 8HP) fluid important | every 37,000 mi (60,000 km) | not a lifetime fill for a heavy turbo off-roader — change ~60k km |
| Brake fluid important | every 36 months | — |
| Timing chain inspection | — | chain-driven — inspect for noise rather than scheduled replacement |
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.
