2.4L (4B12) - PHEV plug-in hybrid
Petrol/Electric
Observe the EV-to-petrol transition. During your test drive, accelerate firmly to engage the petrol engine; notice if there is any hesitation or unusual shuttering, which can be common in higher-mileage examples needing a software update or simple maintenance.
Cycling through all climate control settings. Ensure the air conditioning blows cold and the heating warms up quickly, as the heater core and compressor in these PHEV models are electric-driven and complex to troubleshoot.
Navigate over speed bumps and listen for clunks. The Outlander is a heavier vehicle due to the battery, so check the suspension bushings and sway bar links for play, which may show signs of wear in units used primarily for heavy commuting.
Monitoring the state-of-charge gauge during the drive. Take note of how quickly the bars drop; while some degradation is expected in cars of this age, a very rapid discharge may suggest the drive battery has reached a point where its daily electric-only range is reduced.
Usually marks the point where the initial spark plugs and drive belt check are advised.
Consider a full cooling system flush, specifically for the inverter and battery thermal management loops.
Common stage to assess the condition of the regenerative braking components and suspension struts.
Keep up with the engine oil and filter changes every 10,000km to keep the 4B12 petrol engine running smoothly.
Periodically check the health of the 12V auxiliary battery, as this is essential for starting the car's computer systems.
Ensure the PHEV battery cooling intake vents are kept free of dust and debris for optimal battery longevity.
Flush the brake fluid every two years, as the regenerative braking system can lead to different wear patterns compared to standard vehicles.
Regularly inspect the underside of the vehicle to ensure the battery casing remains free from impact damage or corrosion.
Estimated repair costs if issues arise
As these vehicles age, the total electric range may decrease. Depending on your usage patterns, you might eventually need to budget for a professional battery health diagnostic or, in the long term, a battery pack refurbishment.
The PHEV uses a sophisticated cooling circuit for its electrical components. If this requires attention in the future, it is best handled by a technician familiar with Mitsubishi's hybrid architecture.
Because of the extra weight of the battery pack, suspension bushings and struts can wear faster than in a non-hybrid Outlander. You might want to set aside funds for a refresh if the ride quality becomes less composed.
