2.4L (4B12) - PHEV flagship hybrid
Petrol/Electric
Observe the EV-to-Engine transition while accelerating. Ensure the switch between electric power and the 2.4L engine is smooth, as lurching may suggest the hybrid management software or battery health warrants a closer look.
Check the S-AWC system by finding a safe, quiet patch of road. Gently test the handling to ensure there are no unusual clicks or vibrations from the drivetrain, as persistent noises could indicate wear in the complex all-wheel-drive components.
Monitor the infotainment screen and charge levels. Use the 'Save' or 'Charge' mode to verify the engine successfully drives the generator, which helps confirm the health of the high-voltage electrical system.
Listen carefully at low speeds. Keep the windows down to ensure there is no whining from the electric motors, as unusual high-pitched sounds might suggest early wear in the motor assemblies.
Usually marks the first major inspection of the drive battery cooling system and air filter cleaning.
Often the time to inspect the condition of the drive battery capacity and high-voltage cabling for signs of corrosion or wear.
Consider a comprehensive check of the regenerative braking system and auxiliary belt health.
Ensure the engine oil is changed every 15,000km or 12 months, as the 4B12 engine relies on clean oil for variable valve timing efficiency.
Periodically inspect the charging port for any debris or signs of heat stress to ensure your home or public charging remains efficient.
Keep an eye on the 12V auxiliary battery, as this often bears the brunt of the vehicle's computer systems even when the main hybrid battery is full.
Check the coolant levels for the hybrid battery cooling system specifically, as keeping the battery at the right temperature is vital for longevity.
Ensure the brake pads are inspected regularly, as the regenerative braking system often masks the wear levels compared to standard petrol vehicles.
Estimated repair costs if issues arise
As the vehicle ages, the hybrid battery may hold less charge than when brand new. It is wise to perform a health check to understand its current capacity, and you might eventually need to budget for professional balancing or capacity degradation management.
If this component needs attention in the future due to the high torque of the hybrid system, replacing worn drivetrain mounts or bushings ensures the car remains refined. It is a good idea to set aside funds for this as the vehicle enters higher mileage.
Depending on the car's history and whether it has spent time in salty coastal environments, the friction brakes might require a deep clean or pad replacement due to lower usage from the regenerative braking system. Budgeting for a thorough brake service helps prevent long-term seizing.
