About This Data
The 2018 SEAT Arona has an MOT pass rate of 84.9% based on 47,689 tests — well above the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 30,879 miles on the odometer. With a 15.1% failure rate, the 2018 Arona is rated as "Excellent" for MOT reliability.
If you own or are considering buying a 2018 SEAT Arona, you can expect reliable MOT performance overall. Before your MOT, pay particular attention to tyres: Check tread depth with a 20p coin — if the outer band is visible, the tyre is too worn. Look for bulges, cuts, or embedded objects. Ensure all tyres match the recommended size and load rating. With relatively low average mileage of 30,879 miles, many of these vehicles are still in good mechanical condition.
Tyres — 4.6% of failures
Tyres issues account for 4.6% of MOT failures on 2018 SEAT Arona models. Tyre failures include tread depth below the legal minimum of 1.6mm, cuts, bulges, exposed cords, and incorrect tyre pressure. Tyres are one of the most common and easiest-to-prevent MOT failures. Typical repair costs: £50–200 per tyre. Pre-MOT check: Check tread depth with a 20p coin — if the outer band is visible, the tyre is too worn. Look for bulges, cuts, or embedded objects. Ensure all tyres match the recommended size and load rating.
Brakes — 4.2% of failures
Brakes issues account for 4.2% of MOT failures on 2018 SEAT Arona models. Brake-related failures include worn brake pads, corroded brake discs, leaking brake lines, and faulty brake servos. These are safety-critical components — any brake deficiency will result in an MOT fail. Typical repair costs: £150–400. Pre-MOT check: Listen for squealing or grinding noises. Check brake pedal feel — if it feels spongy or goes to the floor, have the system inspected immediately. Look at brake pad thickness through the wheel spokes (minimum 3mm).
Steering — 2.9% of failures
Steering issues account for 2.9% of MOT failures on 2018 SEAT Arona models. Steering failures include excessive play in the steering wheel, leaking power steering fluid, worn track rod ends, and damaged steering rack. These affect vehicle control and are closely related to suspension wear. Typical repair costs: £150–600. Pre-MOT check: Check for excessive steering wheel play (more than a few inches of free movement). Listen for whining from the power steering pump. Look for fluid leaks under the car near the front wheels.
