Petrol
While accelerating in low gears, listen closely for any metallic rattle from the engine bay, as the timing chain tensioners on the QG18DE engine can sometimes experience wear as they age.
Turning the steering wheel fully to both the left and right while stationary to ensure there is no knocking noise, which could indicate wear in the steering rack or CV joints.
Pay attention to the CVT transmission's behavior if the model is fitted with one; ensure the transition between gears feels smooth without any hesitation or shuddering under light load.
Operating all electronic switches, particularly the central dash-mounted display and heater controls, as these units can occasionally suffer from internal solder joint fatigue in vehicles of this vintage.
Usually the time to ensure the transmission fluid has been serviced, especially if the vehicle has seen regular urban stop-start driving.

A common point to confirm that the alternator and starter motor are still performing within healthy voltage parameters.
Regular oil changes every 10,000km are the best way to keep the QG18DE engine running happily.
Keep an eye on the coolant levels and ensure the radiator hoses feel supple rather than brittle.
Check the tyre pressures regularly to ensure even wear across the tread, as this helps with the Primera's balanced handling.
Ensure the air filter is kept clean to allow the engine to breathe efficiently during your daily commute.
Periodically check your brake fluid levels and colour, as fresh fluid helps maintain a responsive pedal feel.
Estimated repair costs if issues arise
While these engines are quite robust, if you hear persistent rattling, you might eventually need to budget for a chain kit replacement to keep the engine timing precise.
If the transmission starts showing signs of hesitation, it is worth setting aside funds for a professional assessment or a specialist fluid flush to prolong its service life.
As rubber components age, they can become less effective; you might eventually need to budget for replacing various control arm bushings to maintain that original smooth ride quality.
