A 2018 Toyota Auris is now 8 years old, so an average example has covered around 108,000 miles. The final model year of the generation · generally the most sorted build, so mileage, servicing and condition matter more than build-year faults. Check the state safety inspection and service history alongside the documented faults below, which are sorted by whether a 2018 car has usually reached the mileage where they appear.

The 2018 Toyota Auris is 8 years old, so an average example has covered roughly 108,000 miles. At that mileage 1 of the documented faults are already due, so check those first. A further 3 typically appear later in the car's life.

Build the inspection planDocumented onset mileage is at or below the ~108k miles an average 2018 car has covered.
Severe engine rattle or judder during cold starts when the petrol engine first engages, caused by heavy carbon build-up in the EGR valve and intake manifold.
Age, electronics and build-related issues that are not mileage-driven.
Rear brake corrosion because of regenerative braking
12V auxiliary battery failure
Heavy condensation or water pooling inside the front headlight clusters due to failed factory seals, potentially causing electrical shorts or MOT failure.
Toyota Touch 2 infotainment system freezing, randomly rebooting, or dropping Bluetooth connections.
Typically appear later than this year's average mileage · worth budgeting for rather than inspecting.
Hybrid battery decline on very high-mileage cars
Rear bushes and shock wear on high-mileage cars
Inverter electric water pump failure, leading to hybrid system overheating and dashboard warning lights.

Build my inspection planYes, ex-private-hire cars often run past 200,000 miles with the original battery.
Hybrid health check certificate plus a clean MOT record.
Poor cosmetic condition, not mechanical failure.
Unlike conventional CVTs, the Toyota e-CVT uses a planetary gearset with no belts or pulleys, making it exceptionally reliable. However, it still requires a transmission fluid change every 60,000 miles. Check the service history for this specific job, as neglected fluid can lead to whining bearings and eventual gear failure.
The 1.4 D-4D is robust but highly susceptible to DPF blockages if previous owners primarily drove short urban routes. During inspection, pull the dipstick and check if the oil level is significantly above the maximum mark. This indicates active regeneration failures, causing diesel fuel to dilute the engine oil.
The 1.2-litre turbocharged engine is generally reliable but suffers from ignition coil failures and carbon build-up on the intake valves due to direct injection. On a test drive, apply heavy load in a high gear at low RPMs. Any hesitation or misfiring indicates coil degradation or coked valves requiring walnut blasting.
