2.5L VQ25DE V6 Petrol - RWD

Check this by shifting through all gears while stationary and then on the move to ensure the 5-speed automatic transmission transitions smoothly without any noticeable 'flaring' or hesitation.
While driving at low speeds, turn the steering wheel to full lock in both directions to listen for any clicking or knocking sounds that may suggest wear in the CV joints or steering rack bushings.
Inspect this by running the climate control on full heat and then full cold; E51 models can occasionally develop issues with the heater blend door actuators, which can be tricky to access.
While parked on level ground, visually check the underside near the rear suspension for signs of leaking or 'sweating' shocks, as the E51 is a heavy vehicle and the rear air-assisted or standard struts do a lot of heavy lifting.
Usually the time to ensure the spark plugs have been replaced, as accessing the rear bank of the V6 requires significant labor.
A common point to evaluate the condition of the engine mounts, as the VQ25DE generates vibration that can eventually cause these to sag.
Consider having the transmission fluid flushed and checked for metallic debris to prolong the life of the drivetrain.
Stick to high-quality engine oil changes every 8,000km to keep the variable valve timing system operating smoothly.
Keep a close eye on your cooling system; ensure the coolant is fresh and the radiator hoses aren't feeling brittle or hard.
Inspect the cabin air filter regularly, as these vans move a lot of air and the filters can trap a surprising amount of dust.
Check the tire pressures frequently, as the weight of the Elgrand makes it sensitive to alignment and pressure changes.
Ensure the sliding door tracks are kept clean and lightly lubricated to prevent the motor strain that can lead to electrical gremlins.
Estimated repair costs if issues arise
Because the E51 is a substantial van, the rear suspension works quite hard. If the ride starts to feel bouncy or wallowy in the future, you might eventually need to budget for replacing the rear shocks.
If you notice excessive vibration at idle, the engine mounts may have reached the end of their service life. This is a labor-intensive job due to the tight engine bay, so it is helpful to plan for this over time.
The VQ25DE engine is fantastic, but changing the rear spark plugs requires removing the intake manifold. If you get a misfire, it is wise to consider replacing all plugs and potentially the coils as a preventative measure.
