3.5L Hybrid (VQ35HR) - Hybrid/S
Hybrid
Check the transition between electric and combustion power while slowing to a stop. | Note: On some Infiniti Q50 Hybrid models, the seven-speed automatic gearbox can occasionally feel a bit hesitant or 'jerky' during the hybrid system's regenerative braking phase; it's worth noting if it feels unusually harsh.
Listen for any audible whine or clicking from the steering wheel area while maneuvering at low speeds. | Note: This model uses Direct Adaptive Steering (DAS). While innovative, it's worth ensuring the electronic feedback feels consistent and that there are no warning lights on the dash, as these systems can be complex to diagnose.
Cycle through the dual-touchscreen infotainment system while the car is idling. | Note: It is not uncommon for the infotainment software in these early luxury hybrids to show signs of age, such as occasional lag or screen freezes; confirm that all menus and climate controls are responsive.
Check the condition of the hybrid battery health indicator if accessible via the dashboard menu. | Note: Given the age of these vehicles, it is helpful to ensure the hybrid system charges and discharges effectively during your drive, as consistent performance indicates a healthy battery cell balance.
Usually the time for a major service including spark plug replacement and fresh transmission fluid.
Consider a thorough inspection of the hybrid cooling fan and inverter coolant systems.
A point where suspension bushings and engine mounts might show signs of wear and provide a noticeable improvement to ride quality if refreshed.
Keep the engine coolant and inverter coolant systems serviced on schedule to protect the hybrid components.
Regularly clean the hybrid battery cooling vent located near the rear seats to prevent debris buildup.
Stick to high-quality engine oil changes every 10,000km to keep the VQ35HR engine running smoothly.
Check the condition of the 12V auxiliary battery, as these often fail before the main hybrid battery and can cause strange electronic gremlins.
Ensure the transmission fluid is inspected; while often marketed as 'lifetime' fluid, many specialists suggest refreshing it every 80,000km to 100,000km.
Estimated repair costs if issues arise
Because this system is electronic, if the actuator or steering control module requires attention down the road, it is a specialized repair. It is wise to keep a rainy-day fund specifically for advanced electronics.
While these units are generally robust, you might eventually need to budget for a refurbished or replacement battery pack if the car is staying in your family for the long haul.
As the car hits higher mileage, the weight of the hybrid system can lead to faster wear on control arm bushings. Replacing these as a set is a great way to restore that 'new car' luxury feel.
