1.5L (GW4LY) Plug-in Hybrid PHEV - Ultra
PHEV/Petrol
Navigate a series of tight corners and parking manoeuvres to listen for any electronic steering feedback or clunking sounds, as the H6's steer-by-wire system is highly sensitive to alignment.
Pay close attention to the transition between electric and petrol power during moderate acceleration; if the handover feels jerky, consider asking the seller about the recent software update history.
Check the infotainment system responsiveness by cycling through climate and drive mode settings quickly; a lagging screen can sometimes indicate underlying software communication issues.
Monitor the brake pedal feel when slowing down gradually; since it uses regenerative braking, ensure the transition to friction brakes feels smooth and consistent rather than inconsistent.
First major health check of the high-voltage battery system and standard logbook service.
Inspection of brake pads and regenerative braking calibration, plus a check on the cooling system for the hybrid battery pack.
Significant milestone requiring transmission fluid flush and potential inspection of suspension bushings and steering components.
Keep the GWM app updated to ensure your vehicle software remains current with the latest performance patches.
Ensure the charging port door and seals are kept clean and free of debris to maintain a weather-tight connection.
Stick strictly to the manufacturer's recommended service intervals to preserve the validity of the GWM warranty.
Check tyre pressures regularly, as the heavy battery pack makes these vehicles particularly sensitive to under-inflated tyres for fuel economy.
Clean the cabin air filter annually, especially if you drive in high-pollen or dusty environments, to protect the HVAC electronics.
Estimated repair costs if issues arise
While the battery is covered by a long warranty, as the vehicle ages beyond the initial term, you might eventually need to budget for professional diagnostics to monitor cell health.
If the screen encounters a hardware fault after the warranty period, replacing the integrated digital cluster or main unit is a specialised job. It is wise to consider this a future contingency.
Because of the hybrid regenerative braking system, the friction pads often last longer than standard cars; however, they can occasionally seize from lack of use, so plan for a periodic strip and clean during services.
