3.5L (VQ35DE) - SE/SE-R performance trims
Petrol
Gently accelerate from a stop; feel for any 'rubber-banding' or shuddering sensation, as the CVT transmissions in these models can occasionally exhibit hesitation or heat-related fatigue over time.
Listen carefully while steering at low speeds; clunks or pops from the front end may suggest that the sway bar links or control arm bushings have reached the end of their service life given the age of these vehicles.
With the engine at operating temperature, shift between Park, Reverse, and Drive; delayed engagement or a firm 'clunk' might indicate that the engine or transmission mounts are starting to soften or crack.
Inspect the area around the valve covers and oil filter housing for signs of dampness, as the VQ35DE engine is known to develop minor oil seepage around the gaskets as the rubber ages.
Consider checking the cooling system health, specifically replacing the thermostat and inspecting radiator hoses for brittleness.
This is a sensible time to have the suspension dampers and strut mounts inspected for ride quality degradation.
A major milestone; focus on inspecting accessory drive belts, tensioners, and verifying the condition of the spark plugs for optimal V6 performance.
Prioritize regular engine oil changes using high-quality synthetic oil to keep the variable valve timing components happy.
Keep a close eye on your transmission fluid; even if marked as 'sealed', a professional drain and fill can help extend the life of the CVT.
Check your brake fluid quality every two years, as moisture buildup can lead to internal corrosion in the ABS module.
Periodically clear out the cabin air intake near the windscreen to prevent debris buildup and keep the air conditioning system smelling fresh.
Stay on top of coolant flushes to prevent internal radiator sludge, which is important for keeping the transmission cooler efficient.
Estimated repair costs if issues arise
While the CVT is efficient, they do have a finite lifespan. If you notice signs of slippage, you might eventually need to budget for a specialist transmission flush or, in worst-case scenarios, a professional rebuild or replacement.
With the weight of the V6 engine, the front suspension components work quite hard. You might eventually need to budget for replacing the struts and control arm bushings to restore that factory-fresh steering precision.
It is quite common for the valve cover gaskets on the VQ series engine to weep oil over time. If you notice a faint smell of burning oil, you should eventually budget for a gasket refresh to keep the engine bay clean.
