What to look out for

The checks worth doing on a GWM Haval Jolion before you hand over any money. Every documented fault is listed below, each with its own page.

  • Costly issue

    Check the oil dipstick and compare against the service date.

    See why

    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 $500–$5,500 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.

    See why

    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 NZ and 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 $0–$800 to put right.

  • Common issue

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

    See why

    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 NZ and AU.

    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 $350–$900 to put right.

OccasionalEngine $500–$5,500 to fix

Can't confirm for this car

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.

Symptoms to 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

What to check

Check the oil dipstick and compare against the service date. On a cold start, observe the exhaust for blue smoke. Review service history for records of repeated oil top-ups or GWM warranty oil consumption investigation. If a workshop inspection is possible: Remove and inspect spark plugs for oily or carbon-fouled deposits.

Where to look: GW4B15A engine internals, piston rings

Ask the seller

  • “Has the oil level needed topping up between services?”
  • “Has any blue smoke been noticed from the exhaust?”
  • “Has GWM carried out a warranty inspection for oil consumption?”

  • Vibration increases under moderate acceleration
  • Engine rocking visibly when revved in neutral

What to check

With the bonnet open, have an assistant blip the throttle while you observe the engine movement. Excessive rocking or a visible lurch indicates mount failure. Physically check the torque arm mount under the engine for cracking or collapse of the rubber element.

Where to look: Engine mount brackets, front lower torque arm and right-side mount

Ask the seller

  • “Has any vibration or clunk been felt when selecting drive or reverse?”
  • “Have engine mounts been inspected or replaced?”
  • “Is any vibration felt at idle with the air conditioning running?”

Symptoms to 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

What to check

  1. Drive 15-20 minutes with all assists in their default state and count the false warnings — pre-update cars chime almost constantly.
  2. Check the dash for any LSS/ADAS fault message on startup, test the 360 camera in a car park, and confirm whether warnings stay disabled after switching the car off and on.

Where to look: Windscreen camera, driver-monitoring camera above the steering column, surround cameras

Ask the seller

  • “Has the free GWM ADAS/DMS recalibration software update been installed?”
  • “Any dash fault codes for lane-keep or cameras, and were they fixed under warranty?”
  • “Which NZ GWM dealer maintains the car?”
