About Renault 50 Series MOT Data
The Renault 50 Series is a rare vehicle in the UK, with 48 MOT test results recorded in our database spanning 1 manufacture years. It has an overall MOT pass rate of 39.6% and a failure rate of 60.4%, which is significantly below the UK average of approximately 37%.
For Renault 50 Series owners, these results suggest above-average failure risk — thorough pre-MOT checks are recommended. Focus your pre-MOT checks on brakes and steering 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 50 Series is likely to perform.
Brakes — 62.5% of failures
Brakes issues account for 62.5% of MOT failures on the Renault 50 Series. 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 — 43.8% of failures
Steering issues account for 43.8% of MOT failures on the Renault 50 Series. 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.
Lamps, Reflectors and Electrical Equipment — 35.4% of failures
Lamps, Reflectors and Electrical Equipment issues account for 35.4% of MOT failures on the Renault 50 Series. 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.
