💡 What does the warranty cliff mean?
The Suzuki Alto Sz3 shows a moderate increase in MOT failures after warranty. The 35% increase is typical — plan for gradual maintenance cost increases. Peak failure occurs at age 7 (22.7% fail rate).
Note: pass rates may improve for very old vehicles due to survivorship bias — only well-maintained cars remain on the road.

Tyres — 14.6% of failures
Tyres issues account for 14.6% of MOT failures on the Suzuki Alto Sz3. 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 — 9.5% of failures
Brakes issues account for 9.5% of MOT failures on the Suzuki Alto Sz3. 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).
Driver's View of the Road — 7.9% of failures
Driver's View of the Road issues account for 7.9% of MOT failures on the Suzuki Alto Sz3. Driver's View of the Road issues are a common cause of MOT failure. Regular inspection and maintenance of these components helps ensure your vehicle passes its MOT. Typical repair costs: £100–400. Pre-MOT check: Have this system checked during regular servicing. Look for warning signs like unusual noises, vibrations, or dashboard warning lights.
