Listen carefully at low speeds over bumpy roads. It is common for these models to develop worn suspension bushings or sway bar links, which can present as a light clunking noise.
Observe the transmission performance while accelerating smoothly from a standstill. Being a CVT transmission, it is worth noting if there is any hesitation or unusual 'rubber-banding' feeling, as fluid condition is key to longevity in this unit.
Opening the bonnet while the engine is running and observing for any high-pitched squealing. Older accessory drive belts can occasionally show their age, and a quick inspection for cracks or glazing is a smart preventative move.
Operating all interior electronics, specifically the windows and air conditioning. In cars of this age, minor electrical switches can occasionally become sticky or unresponsive due to dust or lack of use.
Usually the time to ensure the spark plugs have been refreshed and the CVT fluid has been inspected or changed to keep the transmission shifting smoothly.
A good point to look at the overall health of the suspension components, as struts and shock absorbers may begin to lose their original damping efficiency.
Consider a comprehensive cooling system check, including checking hoses and the radiator for signs of weeping or age-related brittleness.
Keep up with engine oil changes every 10,000km using a quality 0W-20 or 5W-30 synthetic oil to look after the 1NR-FE engine internals.
Ensure the cabin air filter is replaced annually to keep the heater and air conditioning system breathing fresh air.
Perform a regular check of the engine coolant levels and ensure the fluid is bright and clear rather than discoloured.
Monitor tyre pressures monthly, as the Trezia is quite sensitive to rolling resistance, which can impact your overall fuel efficiency.
Every two years, have the brake fluid tested for moisture content, which is a simple way to maintain consistent stopping power.
Estimated repair costs if issues arise
Regular fluid exchanges are vital for the health of this transmission. If the vehicle history is unclear, you might eventually need to budget for a professional flush to ensure long-term reliability.
If the ride starts to feel a little floaty or harsh over bumps, it is common to consider a suspension refresh. Depending on the car's history, you might eventually need to budget for new struts to restore that 'factory' handling feel.
As part of long-term preventative maintenance, if this component needs attention in the future, it is often best to replace the drive belt at the same time to save on labour.
