Known problems
- Good to know
Early winter squeaks and occasional slow cabin warm-up
Symptoms: after the first winter some cars develop squeaks from rear suspension rubber bushings, especially where road salt is used; a few owners also report weak initial cabin heat traced to air trapped in the coolant loop rather than a heater fault.
What to do: Have squeaking rubber bushings inspected and lubricated or replaced if needed — often a cheap seasonal fix; if cabin heat is weak, ask the service to bleed the coolant system and check its level. Keep the underbody and suspension clean through salt-belt winters.
- Good to know
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; owners rely on aftermarket russification, and a careless major over-the-air firmware update on a grey-import car that was not properly activated can disable 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.
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 — 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.
