Petrol
Operate all infotainment and cabin comfort controls, specifically the heated/ventilated seats and the electronic parking brake, to ensure the complex cabin electronics are functioning reliably.
During your inspection, check the inner edges of the front tyres for uneven wear patterns, which may indicate that the suspension bushings or alignment require attention.
Gently accelerate from a stop to cruising speed to check for any hesitation or 'hunting' in the six-speed automatic transmission, as smooth shifts are key to a well-maintained Lambda II powertrain.
Turn the steering wheel fully to both locks while stationary to listen for any groaning or metallic clicks from the power steering pump or rack, which can be sensitive on larger Hyundai sedans of this era.
Usually marks the point for a proactive transmission fluid flush and check of the serpentine belt tensioner.
A common window for inspecting the suspension struts and sway bar links for any play or knocking sounds.
Typically the time to ensure the cooling system components, such as hoses and the radiator, are performing at their peak.
Ensure the oil has been changed consistently every 10,000km using high-quality synthetic oil to keep the GDi engine clean.
Keep an eye on the coolant reservoir levels; using the correct Hyundai-spec coolant prevents internal engine corrosion.
Verify that the cabin air filter is replaced regularly to keep the interior climate control system smelling fresh and working efficiently.
Regularly treat the leather upholstery with a quality conditioner to prevent the New Zealand sun from cracking the interior surfaces.
Have a local mechanic perform a multi-point inspection every 12 months to catch any minor electronic gremlins early.
Estimated repair costs if issues arise
Because this engine uses Gasoline Direct Injection, it's common for carbon deposits to build up on the intake valves over high mileage. If the engine feels a little sluggish in the future, you might need to budget for a professional intake decarb service.
Given the Grandeur's weight and comfort-focused ride, the rubber bushings may naturally wear over time. Depending on your driving habits, you might eventually need to budget for a refresh of the front control arm bushings to restore that 'new car' ride quality.
The six-speed transmission is robust, but if you notice delayed engagement, it is worth consulting a transmission specialist. Future budget planning for a solenoid clean or valve body service can help prolong the life of your gearbox.
