3.6L Pentastar V6 (ERB) - Luxury/Limited Trim
Petrol
During the test drive, shift into manual mode and ensure the 8-speed transmission shifts smoothly without any hesitation or 'flaring' between gears, as the ZF gearbox can sometimes display quirks if the fluid hasn't been serviced.
Turn the steering wheel fully from lock to lock while idling; listen for any whining sounds, as the electro-hydraulic steering systems in these units can be sensitive to fluid degradation.
Spend a few minutes testing every button on the Uconnect infotainment screen, paying close attention to touch responsiveness and GPS lock, as the head units in these models can occasionally experience software glitches.
Before starting the engine cold, check the floor mats and the underside of the dashboard for any signs of moisture, as the sunroof drainage tubes can sometimes become blocked in older vehicles, leading to water ingress.
Usually marks the time to consider a transmission fluid and filter service to keep the ZF transmission shifting like new.
A common point where suspension components like control arm bushings and sway bar links might show signs of wear given New Zealand's varied road surfaces.
The general recommendation is to inspect the accessory drive belts and tensioners to prevent any cooling system or charging system interruptions.
Prioritise regular engine oil changes using the correct specification synthetic oil to keep the Pentastar's variable valve timing system happy.
Keep an eye on the coolant condition, as keeping the cooling system fresh helps protect the integrity of the radiator and water pump.
Ensure your battery remains in top health, as these cars are quite sensitive to voltage drops which can cause false warning lights.
Periodically clear out the cabin air intake at the base of the windscreen to prevent debris from blocking the HVAC system.
Take time to inspect the brake rotors and pads annually, especially if the vehicle does frequent city driving, to ensure consistent stopping power.
Estimated repair costs if issues arise
Given the weight of the 300C, the front suspension components work hard. You might eventually need to budget for new control arms or bushings to maintain that signature smooth ride.
If this component needs attention in the future, the estimated cost in NZ is focused on refreshing the water pump and thermostat housing, which are standard maintenance items for the Pentastar V6 as the vehicle ages.
Depending on the car's history, you might eventually need to budget for a genuine ZF transmission service kit, which includes the pan and integrated filter, to ensure long-term longevity.
