Lexus Is250 MOT Reliability Overview
The Lexus Is250 is a well-known vehicle in the UK, with 158,105 MOT test results recorded in our database spanning 9 manufacture years. It has an overall MOT pass rate of 80.7% and a failure rate of 19.3%, which is well above the UK average of approximately 37%.
Based on this data, the Lexus Is250 earns a "Excellent" reliability rating. The average Lexus Is250 presents for MOT with approximately 68,263 miles on the clock. Manufacture year matters: 2012 models achieve the highest pass rate at 86.3%, while 2005 models have the lowest at 78.0%. This 8.3 percentage point difference suggests notable variation in build quality or component durability across production years.
The most common MOT failure for the Lexus Is250 is Tyres, affecting 16.1% of all tests. 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. The second most common issue is Brakes at 15.0%. Lamps, reflectors and electrical equipment rounds out the top three at 7.4%. Together, these top 3 failure categories account for a significant portion of all MOT failures for this model.

What Fails Most
Best Year to Buy
All manufacture years perform similarly at ~78.8%.
Based on 2024 MOT test results only — the most recent data available. "Built" = year of manufacture. Cars need their first MOT at 3 years old, so the newest cars shown are from ~3 years ago.

💡 What does the warranty cliff mean?
The Lexus Is250 shows a moderate increase in MOT failures after warranty. The 37% increase is typical — plan for gradual maintenance cost increases. Peak failure occurs at age 18 (30.0% fail rate).
Note: pass rates may improve for very old vehicles due to survivorship bias — only well-maintained cars remain on the road.
* High Fail Rate badge indicates an MOT pass rate below 65% (failure rate above 35%).

About Lexus Is250 MOT Data
The Lexus Is250 is a well-known vehicle in the UK, with 158,105 MOT test results recorded in our database spanning 9 manufacture years. It has an overall MOT pass rate of 80.7% and a failure rate of 19.3%, which is well above the UK average of approximately 37%.
For Lexus Is250 owners, these results suggest a reliable vehicle that generally passes its MOT without major issues. Focus your pre-MOT checks on tyres and brakes 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 Is250 is likely to perform.
Tyres — 16.1% of failures
Tyres issues account for 16.1% of MOT failures on the Lexus Is250. 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 — 15.0% of failures
Brakes issues account for 15.0% of MOT failures on the Lexus Is250. 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 — 7.4% of failures
Lamps, reflectors and electrical equipment issues account for 7.4% of MOT failures on the Lexus Is250. 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.
