About This Data
The 1998 Maserati Quattroporte has an MOT pass rate of 70.0% based on 80 tests — slightly above the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 71,385 miles on the odometer. With a 30.0% failure rate, the 1998 Quattroporte is rated as "Good" for MOT reliability.
If you own or are considering buying a 1998 Maserati Quattroporte, you can expect reliable MOT performance overall. Before your MOT, pay particular attention to brakes: 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). At 71,385 average miles, these vehicles are in the mid-range where component wear starts to become a factor.
Brakes — 22.5% of failures
Brakes issues account for 22.5% of MOT failures on 1998 Maserati Quattroporte 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).
Lamps, reflectors and electrical equipment — 17.5% of failures
Lamps, reflectors and electrical equipment issues account for 17.5% of MOT failures on 1998 Maserati Quattroporte 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: £5–50. Pre-MOT check: Walk around the car and check every light — 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.
Steering — 10.0% of failures
Steering issues account for 10.0% of MOT failures on 1998 Maserati Quattroporte 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.
