Based on this data, the Subaru Impreza earns a "Good" reliability rating. The average Subaru Impreza presents for MOT with approximately 86,295 miles on the clock. Manufacture year matters: 2017 models achieve the highest pass rate at 90.0%, while 1997 models have the lowest at 57.2%. This 32.8 percentage point difference suggests notable variation in build quality or component durability across production years.
The most common MOT failure for the Subaru Impreza is Suspension, affecting 25.9% of all tests. Suspension failures typically involve worn bushes, leaking shock absorbers, broken coil springs, and damaged suspension arms. These affect ride quality, tyre wear, and road holding. The second most common issue is Brakes at 21.1%. Lamps, Reflectors and Electrical Equipment rounds out the top three at 21.0%. Together, these top 3 failure categories account for a significant portion of all MOT failures for this model.

📉 How Age Affects Reliability
MOT failure rate by vehicle age for the Subaru Impreza. The dashed red line marks when the manufacturer warranty typically expires (3 years).
Line chart showing MOT failure rate by vehicle age from 3 to 20 years, with warranty expiry marked at 3 years.
💡 What does the warranty cliff mean?
The Subaru Impreza shows a moderate increase in MOT failures after warranty. The 32% increase is typical — plan for gradual maintenance cost increases. Peak failure occurs at age 14 (37.6% 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%).

Use our detailed year-by-year breakdown and failure analysis below to understand how your specific Impreza is likely to perform.
Suspension — 25.9% of failures
Suspension issues account for 25.9% of MOT failures on the Subaru Impreza. Suspension failures typically involve worn bushes, leaking shock absorbers, broken coil springs, and damaged suspension arms. These affect ride quality, tyre wear, and road holding. Typical repair costs: £200–500. Pre-MOT check: Look for uneven tyre wear, listen for clunking over bumps, and check if the car pulls to one side. A bouncy ride suggests worn shock absorbers. Visually inspect coil springs for cracks.
Brakes — 21.1% of failures
Brakes issues account for 21.1% of MOT failures on the Subaru Impreza. 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 — 21.0% of failures
Lamps, Reflectors and Electrical Equipment issues account for 21.0% of MOT failures on the Subaru Impreza. 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.
