Petrol
Check the transmission shift quality by ensuring the gear changes are smooth and free of hesitation. | Detail: The 4-speed INVECS-II automatic transmissions are generally reliable, but in vehicles of this age, it is worth monitoring for delayed engagement when shifting from Park to Drive.
Test the suspension by driving over a few speed bumps at low speeds while listening for clunks. | Detail: The Grandis is a heavier vehicle, so it is common to consider that front sway bar links and suspension bushings may eventually require refreshing to maintain that smooth ride.
Check the interior climate control by cycling through all vent settings and temperature ranges. | Detail: It is worth keeping an eye on the blend door actuators, as these can sometimes become sticky in older models, potentially affecting the cabin temperature consistency.
Check the condition of the engine oil filler cap and the coolant reservoir during your inspection. | Detail: While the 4G69 engine is quite robust, in cars of this age, it is good practice to ensure there are no signs of oil and coolant mixing, which can be an indicator of general wear over long service intervals.
Consider a full cooling system flush and check of all rubber hoses.
Ensure the timing belt and associated tensioners have been replaced, as this is a vital maintenance step for the 4G69 engine.
Assess the state of the alternator and starter motor for potential future reliability.
Keep up with engine oil changes every 10,000km using a high-quality 5W-30 or 10W-30 synthetic oil.
Ensure the transmission fluid is clean and red, which helps extend the life of the automatic gearbox.
Regularly inspect the timing belt service history, as this is a non-negotiable for engine longevity.
Check the condition of your cabin air filter to keep the air quality fresh for your passengers.
Keep an eye on tire pressures, as the Grandis can be sensitive to uneven wear if the alignment is slightly off.
Estimated repair costs if issues arise
If the service history is unclear, you might eventually need to budget for a timing belt and water pump kit to ensure the engine remains protected for years to come.
Given the weight of the vehicle, you might eventually need to budget for replacing worn suspension bushes or struts if the steering starts to feel a bit loose on uneven roads.
Depending on the car's history, you might eventually need to budget for a professional transmission fluid flush to keep the gear shifts as smooth as the day it left the factory.
