Saab 9-5 MOT Reliability Overview
The Saab 9-5 is a very popular vehicle in the UK, with 413,870 MOT test results recorded in our database spanning 16 manufacture years. It has an overall MOT pass rate of 63.8% and a failure rate of 36.2%, which is around the UK average of approximately 37%.
Based on this data, the Saab 9-5 earns a "Average" reliability rating. The average Saab 9-5 presents for MOT with approximately 102,549 miles on the clock. Manufacture year matters: 2012 models achieve the highest pass rate at 80.2%, while 1998 models have the lowest at 56.6%. This 23.6 percentage point difference suggests notable variation in build quality or component durability across production years.
The most common MOT failure for the Saab 9-5 is Suspension, affecting 30.6% 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 29.9%. Lamps, Reflectors and Electrical Equipment rounds out the top three at 25.4%. 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
Based on MOT data, 2010 models have the highest pass rate at 71.8%.
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 Saab 9-5 shows a moderate increase in MOT failures after warranty. The 42% increase is typical — plan for gradual maintenance cost increases. Peak failure occurs at age 15 (42.5% 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 9-5 is likely to perform.
Suspension — 30.6% of failures
Suspension issues account for 30.6% of MOT failures on the Saab 9-5. 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 — 29.9% of failures
Brakes issues account for 29.9% of MOT failures on the Saab 9-5. 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 — 25.4% of failures
Lamps, Reflectors and Electrical Equipment issues account for 25.4% of MOT failures on the Saab 9-5. 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.
