  GW4B15A 1.5T Excessive Engine Oil Consumption

  A proportion of GW4B15A 1.5T engines in early Jolion production have shown above-average oil consumption, with some owners reporting the need to top up between scheduled services. The issue is associated with piston ring sealing on pre-2022 build-date units and can be identified by blue-tinged exhaust smoke on cold morning start-ups. GWM Australia carried out engine inspections under warranty on affected vehicles. Pre-owned examples without documented warranty investigation of this issue should be treated with caution.

  What you would notice

  • Oil level dropping noticeably between services
  • Light blue smoke from exhaust on cold start
  • Burning oil smell after hard acceleration
  • Fouled or oily spark plugs on inspection

  Typically ≈A$460–5,060 to put right.

• Common issue

  Drive 15-20 minutes with all assists in their default state and count the false warnings — pre-update cars chime almost constantly.

  Driver-monitoring and lane-keep false alarms; LSS fault codes

  The Jolion is one of the models GWM explicitly named when it confirmed in September 2024 that engineers were rewriting ADAS and driver-monitoring software for Australia, after complaints of rest-break nags minutes into a journey and false alerts for violations that never happened. CarsGuide owner reports also include lane-keep (LSS) fault codes on 2022 cars and a frozen 360-degree camera on a 2025 car. The fix is a free software update through GWM dealers, but many used examples have never had it applied, and camera/radar faults outside warranty are the owner's cost.

  What you would notice

  • 'Take a rest' or attention warnings soon after setting off
  • Constant lane-keep chimes and steering tugs
  • LSS or driver-assist fault messages on the dash
  • 360-degree camera freezing or dropping out

  Typically ≈A$0–740 to put right.

• Common issue

  With the bonnet open, have an assistant blip the throttle while you observe the engine movement.

  Engine Mount Deterioration Causing Low-Frequency Vibration

  Hydraulic and rubber engine mounts on the Haval Jolion have been reported to deteriorate prematurely, particularly the front lower torque arm mount. Worn mounts allow excessive engine movement under acceleration and load, resulting in a low-frequency vibration felt through the cabin and a clunk when moving between drive and reverse. The issue has been identified on units with as few as 40,000 km. Aftermarket replacement mounts are available but OEM sourcing through GWM dealers can have extended lead times in Australia.

  What you would notice

  • Low-frequency vibration through the cabin, particularly at idle
  • Clunk or thud when engaging drive or reverse from park
  • Vibration increases under moderate acceleration
  • Engine rocking visibly when revved in neutral

  Typically ≈A$320–830 to put right.
