Porsche 718 common problems and MOT failures
What goes wrong on a used Porsche 718, year by year: known faults from UK buying guides, the parts flagged at MOT more than on other cars (from 2,983 MOTs done during 2023–2025), and what to check before you buy one.
The 2016 Porsche 718
Too few Porsche 718 cars first registered in 2016 had an MOT during 2025 for reliable MOT figures. There are no known faults on record for this year in the UK buying guides we use, so the rest of this page covers the Porsche 718 as a whole.
What to check on a 2016 car
- MOT history
Check the reg below: its MOT history shows what has been failed or advised, and whether the mileage adds up.
- Service history
Look for regular servicing and receipts for big jobs like a cambelt or clutch.
- Finance and write-offs
MOT records don’t show outstanding finance or insurance write-offs. A history check does.
- Test drive
Listen for knocks over bumps, check every warning light goes out, and make sure the gears and brakes feel right.
Other years

Where this comes from: MOT figures are the DVSA’s anonymised results for every MOT test done in Great Britain during 2023–2025, grouped by the year each car was first registered. How many are on the road is from the Department for Transport’s vehicle licensing statistics. Known faults are from UK buying guides, in our own words, with links. How we score
