About This Data

The 1999 Fiat Seicento Mia has an MOT pass rate of 32.4% based on 37 tests โ€” significantly below the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 71,337 miles on the odometer. With a 67.6% failure rate, the 1999 Seicento Mia is rated as "Very Poor" for MOT reliability.

If you own or are considering buying a 1999 Fiat Seicento Mia, be prepared for above-average maintenance costs. Before your MOT, pay particular attention to brakes: Listen for squealing or grinding noises. Check brake pedal feel โ€” 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). At 71,337 average miles, these vehicles are in the mid-range where component wear starts to become a factor.

Brakes โ€” 156.8% of failures

Brakes issues account for 156.8% of MOT failures on 1999 Fiat Seicento Mia models. Brake-related failures include worn brake pads, corroded brake discs, leaking brake lines, and faulty brake servos. These are safety-critical components โ€” any brake deficiency will result in an MOT fail. Typical repair costs: ยฃ150โ€“400. Pre-MOT check: Listen for squealing or grinding noises. Check brake pedal feel โ€” 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).

Lamps, Reflectors and Electrical Equipment โ€” 105.4% of failures

Lamps, Reflectors and Electrical Equipment issues account for 105.4% of MOT failures on 1999 Fiat Seicento Mia models. Lighting failures cover all external lights: headlights, tail lights, brake lights, indicators, fog lights, and reflectors. A single blown bulb will cause an MOT fail. This is one of the most preventable failure categories. Typical repair costs: ยฃ5โ€“50. Pre-MOT check: Walk around the car and check every light โ€” headlights (dipped and main beam), side lights, tail lights, brake lights, indicators, hazard lights, reverse light, rear fog light, and number plate lights. Replace any blown bulbs before the test.

Exhaust, Fuel and Emissions โ€” 48.6% of failures

Exhaust, Fuel and Emissions issues account for 48.6% of MOT failures on 1999 Fiat Seicento Mia models. Emissions failures occur when exhaust gases exceed legal limits for carbon monoxide (CO), hydrocarbons (HC), or particulate matter (diesel). Common causes include faulty oxygen sensors, clogged catalytic converters, or DPF issues on diesel vehicles. Typical repair costs: ยฃ100โ€“1,000+. Pre-MOT check: If the engine management light is on, get it diagnosed before the MOT. For diesel cars, ensure the DPF has completed a regeneration cycle. Regular servicing and using premium fuel before the test can help.
