About This Data
The 2017 Porsche Cayman has an MOT pass rate of 94.8% based on 5,762 tests — well above the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 26,219 miles on the odometer. With a 5.2% failure rate, the 2017 Cayman is rated as "Excellent" for MOT reliability.
If you own or are considering buying a 2017 Porsche Cayman, you can expect reliable MOT performance overall. Before your MOT, pay particular attention to tyres: 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. With relatively low average mileage of 26,219 miles, many of these vehicles are still in good mechanical condition.
Tyres — 2.0% of failures
Tyres issues account for 2.0% of MOT failures on 2017 Porsche Cayman models. 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 — 0.6% of failures
Brakes issues account for 0.6% of MOT failures on 2017 Porsche Cayman models. 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).
Visibility — 0.3% of failures
Visibility issues account for 0.3% of MOT failures on 2017 Porsche Cayman models. Visibility failures relate to the windscreen, wipers, washers, mirrors, and view-obstructing damage. Cracks in the windscreen swept area, ineffective wipers, or empty washer bottles are common causes. Typical repair costs: £10–300. Pre-MOT check: Check the windscreen for chips and cracks — damage larger than 10mm in the driver's swept area or 40mm elsewhere will fail. Test washers and wipers. Ensure both door mirrors are intact and adjustable.
