Known problems
- Worth watching
Software updates and Russian localization on parallel-import cars
Symptoms: the car ships with Chinese-market software and voice assistant, so menus and some functions are not natively in Russian; installing a major over-the-air firmware jump (owners reported trouble around the 7.x releases) on a grey-import car that was not properly activated can disable features or lock functions until the car is re-activated.
What to do: Treat firmware as fragile on a parallel import: do not blindly accept a major OTA update — check with a Lixiang specialist first, keep the car on a known-stable version, and have Russian localization and apps installed by a shop that does it properly. Before buying, confirm the seller completed a clean activation.
- Worth watching usually 6,000–37,000 mi (10,000–60,000 km)
Air-suspension compressor failure in cold, damp climates
Symptoms: on air-suspension cars the compressor can take in and hold moisture that freezes in winter, so the car sits low or is slow to raise ride height and logs suspension errors; some cars have needed a compressor replacement relatively early.
What to do: If the car sits low in the morning, levels slowly, or shows a suspension warning, have the air-suspension compressor and its air dryer checked before the fault does further damage — budget for it, as it is a known and not-cheap repair.
- Good to know
Range-extender runs hard in deep cold: higher fuel use, more engine noise, heating quirks
Symptoms: in hard winter the petrol range-extender fires up more often to make both cabin heat and electricity, so fuel use climbs, the engine is more audible in an otherwise near-silent car, EV-only range drops, and owners have noted washer fluid freezing in the nozzles because there is little engine heat up front.
What to do: This is normal EREV physics, not a fault — expect the generator to run more and burn more fuel in severe cold; use proper winter (-30) washer fluid, and pre-condition the cabin while plugged in where possible. Only worry if the engine runs constantly at normal temperatures.
Service schedule
| Item | Interval | Notes |
|---|---|---|
| Engine oil & filter change (range-extender generator engine) | every 6,000 mi (10,000 km) or 12 months | the 1.5T petrol engine drives no wheels — it only spins a generator — but it still needs regular oil. Change roughly every 10,000 km / 12 months, and shorten the interval if the range-extender runs a lot (deep cold, depleted battery, long highway stints on an empty battery). Direct injection is fuel-quality sensitive, so use good petrol. |
| Tyre rotation & condition check | every 6,000 mi (10,000 km) | a heavy battery plus instant electric torque can wear tyres quickly and unevenly on this large SUV — rotate and check regularly. |
| Cabin (pollen) filter change | every 9,000 mi (15,000 km) or 12 months | one of the few frequent consumables on an EREV; change yearly, more often in dusty or pollen-heavy conditions. |
| Range-extender engine coolant important | every 37,000 mi (60,000 km) or 60 months | long-life coolant for the petrol generator engine; check level and condition at every service and replace on the long interval per the maker's schedule. |
| Reduction-gear / drive-unit oil inspection | every 37,000 mi (60,000 km) | single-speed reducers on the front and rear e-axles — inspect for leaks and noise; the oil is a long-life / inspection item, not a frequent change. |
| Battery / drive-unit (thermal-management) coolant inspection important | every 12 months | separate cooling loop for the traction battery and electric motors — check level and condition yearly; the fluid itself is a long-interval replacement item. |
| Brake caliper clean & lubricate important | every 12 months | because regen does most of the braking, the friction brakes are rarely worked hard — clean and grease the caliper slides/guide pins yearly, especially in salt-belt winters, so calipers do not seize or corrode. |
| Brake fluid important | every 24 months | still hygroscopic even though regen braking means the friction brakes see light use — replace on time. |
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.
