Which Jolion have you got?
The petrol Jolion has a 1.5-litre turbo engine and a seven-speed dual-clutch automatic. The hybrid arrived in August 2022 with a 1.5-litre petrol engine, an electric motor and a small 1.6 kWh battery, through a Dedicated Hybrid Transmission. In June 2024 the hybrid changed to a newer model based on the Haval Chitu, and in October 2025 Ultra became Vanta and non-hybrids gained stop/start.
Those changes matter when you're ordering parts or a software update, so give the mechanic the year and the badge on the boot.
Common Haval Jolion problems
None of these come from a recall. They're owner questions answered by CarsGuide, so treat them as things to check.
Hesitation from a stop. A 2025 Lux owner said the car felt dangerous pulling out. CarsGuide linked that to the dual-clutch gearbox and electronic throttle, and suggested a dealer check, a possible software update and a complaint to Haval if it isn't resolved.
Revs but won't go into gear. On a 2023 car this could be anything from low fluid to a serious gearbox failure. Report it early so it stays a warranty matter. Transmission slipping explains more, and if it happens in traffic, get to the side of the road.
Low oil. Some oil use is normal in modern engines. Check the dipstick on a cold car and top up with the oil used at the last service.
Water in the boot. On a 2021 car CarsGuide pointed to the tail-light seal or tailgate seal. A hose and a helper inside will usually find it.
LSS warning light. That's the lane-keeping system. It may be a dirty sensor or camera, so clean the windscreen in front of the camera first. If it stays on, it's a fault for the dealer.
A burning smell. That isn't normal in a nearly new car. One 2024 Ultra Hybrid owner noticed it at 9,000 km, and CarsGuide said it needed urgent inspection. If it's strong, or there's smoke, pull over and switch off.
When a Jolion is due
CarExpert's December 2025 review gives the first service at 12 months or 10,000 km, then later services at 15,000 km intervals. Its Lux listing says every 12 months or 15,000 km, whichever comes first. The first service is the one people miss, so follow the book that came with your car.
If you drive ride-share or do mostly short trips, ask whether the book's shorter intervals for hard use apply to you.
Warranty: the part to get right
CarExpert lists seven years and unlimited kilometres. A qualified independent mechanic can service your Jolion to Haval's schedule and specifications, and that does not by itself void the new car warranty.
A missed service is a different story. CarsGuide warns a skipped service can jeopardise a claim, especially on the gearbox. Ride-share use also changes the cover: one hybrid owner's battery cover dropped to 8 years and 150,000 km, and the car had gone past it. So check your conditions if you drive for work.

If this Jolion were ours
While it's under warranty, we'd take any gearbox, hybrid or electronic fault to a GWM dealer and ask for it in writing, even if they can't reproduce it. We'd keep the routine servicing on time, with a local mechanic or the dealer, and keep every invoice. Out of warranty, a mechanic who regularly works on dual-clutch gearboxes is the one to find.
