3.5L J35Y V6 Hybrid - Sport Hybrid SH-AWD
Petrol/Electric
Engage the Sport Hybrid SH-AWD system by accelerating moderately while turning; listen for any hesitation or clunking from the rear electric motor units, as these systems are complex and benefit from a smooth response.
Cycle through the 'Integrated Dynamics System' modes while stationary and moving; observe if the transition between EV mode and V6 petrol engine power feels fluid, as a jerky transition might suggest a need for a software calibration or sensor check.
Check the infotainment and head-up display functionality by navigating through all menus; ensure the dual-screen interface responds promptly, as these intricate electronics are specific to the KC2 generation and can occasionally require attention.
Monitor the braking feel during gentle stops; since this model uses a sophisticated regenerative braking system, the pedal should feel linear and consistent rather than grabby or uneven.
Consider a comprehensive fluid flush, including the SH-AWD transmission and rear motor gear oil to maintain the efficiency of the hybrid drivetrain.
A common point to inspect the engine mounts and suspension bushings, as the torque from the J35Y V6 and the weight of the hybrid system can place consistent demands on these components.
Typically the time to assess the overall health of the hybrid battery pack capacity through a professional diagnostic scan to ensure your real-world range remains optimal.
Prioritize regular engine oil changes using high-quality synthetic lubricants to keep the complex VCM (Variable Cylinder Management) system functioning smoothly.
Keep a close eye on the SH-AWD system fluids, as clean fluid is essential for the longevity of the rear-mounted twin-motor unit.
Periodically clear out the hybrid battery cooling vents located in the cabin to ensure the battery remains at its peak operating temperature.
Ensure the 12V auxiliary battery is tested annually, as a weak battery in these high-tech vehicles can occasionally trigger phantom electronic warnings.
Maintain the braking system by having the regenerative brake calibration checked periodically to ensure the transition to physical friction brakes is seamless.
Estimated repair costs if issues arise
In cars of this age, it is wise to keep in mind that the hybrid battery is a long-term component. If it eventually requires replacement, it is a significant task that involves sourcing specialized cells.
The SH-AWD system is a marvel of engineering. Depending on the car's history, you might eventually need to budget for specialized servicing of the rear electric drive units to ensure continued performance.
If the active suspension components show signs of wear, replacing these advanced dampers can be an investment in maintaining the Legend's signature ride quality.
