2.0L (MR20DD) - S-Hybrid fuel efficiency model
Hybrid
Check this by shifting through the CVT range while stationary; if you notice a slight delay or shudder, it is common in vehicles of this age to consider a transmission fluid flush to maintain smoothness.
While driving at low speeds, listen for any light clicking from the front end, as suspension bushings and sway bar links often show their age on NZ roads and may eventually need inspection.
During the test drive, pay attention to the S-Hybrid stop-start system; if it seems hesitant to re-engage the engine, it is helpful to note that the secondary auxiliary battery may be nearing the end of its typical lifespan.
While parked, verify the sliding door operation; if the motors sound strained, it is wise to keep the tracks clean to prevent future tension on the internal mechanisms.
Usually marks the point where cooling system hoses and thermostat health should be reviewed.
Common timeframe to consider inspecting the S-Hybrid electrical connections and the health of the primary starter/alternator motor.
A good milestone to have the suspension dampers and strut mounts assessed for fatigue.
Keep up with 10,000km oil change intervals using high-quality synthetic 0W-20 oil to keep the direct-injection system running happily.
Check the CVT fluid every 40,000km to ensure the transmission continues to operate with the reliability these units are known for.
Have your mechanic test the charge levels of both the main battery and the S-Hybrid auxiliary battery during your annual WOF.
Keep the sliding door rollers lubricated with a silicone-based spray to ensure smooth movement.
Ensure the air intake filter is clean to maintain that excellent fuel efficiency the MR20DD engine is famous for.
Estimated repair costs if issues arise
Future Budget Planning: While the CVT is generally reliable with care, if the transmission fluid has not been changed, you might eventually need to budget for a professional flush to ensure long-term longevity.
Future Budget Planning: This secondary battery powers the electronics while the engine is stopped. If you notice the stop-start system isn't engaging as often, you might need to budget for a high-quality replacement.
Future Budget Planning: Given the weight of the Serena, the front struts and sway bar links work hard. Depending on the car's history, you might eventually need to budget for a suspension refresh to restore the ride quality.
