💡 What does the warranty cliff mean?

The Morgan Roadster shows a relatively stable failure rate after warranty — the change of 0% is negligible. Peak failure occurs at age 17 (17.9% fail rate).

Note: pass rates may improve for very old vehicles due to survivorship bias — only well-maintained cars remain on the road.

Focus your pre-MOT checks on lamps, reflectors and electrical equipment and lamps, reflectors and electrical equipment for the best chance of a first-time pass. Use our detailed year-by-year breakdown and failure analysis below to understand how your specific Roadster is likely to perform.

Lamps, Reflectors and Electrical Equipment — 6.1% of failures

Lamps, Reflectors and Electrical Equipment issues account for 6.1% of MOT failures on the Morgan Roadster. 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.

Lamps, reflectors and electrical equipment — 5.5% of failures

Lamps, reflectors and electrical equipment issues account for 5.5% of MOT failures on the Morgan Roadster. 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.

Brakes — 4.6% of failures

Brakes issues account for 4.6% of MOT failures on the Morgan Roadster. 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).
