The picture
Across 902 MOT tests, the Corsa Ultimate Nav Turbo Auto returns 86.7% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is wipers that don't clear the screen. A seriously damaged tyre and a defective wiper blade round out the top three. Average tested mileage sits at 13,936, which is the lens to read those failure rankings through. If you own one and the next test is close, the ranked list below is a sensible pre-test checklist.

Year-band analysis
First-time MOT pass rate split by registration band. Pass rates barely move across bands here, so the year you buy Vauxhall Corsa Ultimate Nav Turbo Auto makes little measurable difference to MOT outcomes.
Best band to buy
88.8%
2018–2020 registration
the 2018–2020 band climbs to 88.8% — a 0.4-point improvement. Failures here are mostly wear items: does not clear the windscreen effectively, blade defective — the structural issues that drag down older examples don't appear in the top-10 for this band.
Band to be cautious about
88.4%
2021+ registration
On the 2021-on band, the data shows a 88.4% pass rate against a fleet average of 88.8% on the newer band. The main culprits logged at test: has a cut in excess of the…, does not clear the windscreen effectively, and blade defective. Average mileage on test for this band is 14,638 miles — high-mileage wear items are a recurring theme.
Best band to buy: 2018-2020 (88.8% first-time pass). Worst band to avoid: 2021+ (88.4% pass). That's a 0.4-point spread across 855 older tests and 1,392 newer ones — year of build makes a material difference on this model.

Verbatim faults logged by owners on honestjohn.co.uk over recent years. We didn't summarise — these are the words people typed in.
Report of repeated failures of coil packs on a 2015 Vauxhall Corsa 'Limited Edition'. First coil pack failed in 2017. Coil pack failed again in January 2019. Dearer wants to charge £250 to replace the coil packs.
Report of 2014 Vauxhall Corsa 1.4 torque converter automatic randomly going into limp mode (yellow symbol appear on dash of car with spanner in) and hardly move. Car regularly driven about town. If driver turned the engine off then restarted the fault would clear and the car drove normally. Owner took it twice to supplying Vauxhall dealer but diagnostic tests couldn’t find a stored fault. They replaced an ignition coil and a spark plug. The fault continues to happen intermittently (weeks in between or once 3 times in 1 day). Vauxhall dealer recommended an independent member of http://www.fer.co.uk /
Report of driver's information screen of new 2018 Vauxhall Corsa 1.4 Turbo randomly going blank. This displays individual pressures of each of the four wheels and autumn condensation might be affecting the TPMS and hence the info screen.
Report of repeated fault with engines in 25,000 mile March 2016 Vauxhall Corsa 1.0T, thought to be LSPI (Low Speed Pre-Ignition Detonation). Since February 2016 Vauxhall dealer has: Replaced spark plugs and leads - Fault returned; Stripped engine, replaced pistons, conrods and bearings - Fault returned, engine failed; Replaced engine - (Vauxhall Exchange Engine). This engine failed before it left the workshop. Stripped the replacement engine reported back to Vauxhall and is now fitting a second replacement engine. Owner thinks that the Exchange engines are re-conditioned, not new, are already faulty and may have damage in the actual block. He thinks that after suffering LSPI the block may have stress fractures that are not detected or repaired and only the internal components are replaced. This may be the reason the 1st replacement engine failed before leaving the workshop.
Report of timing chain of 2015 Vauxhall Corsa 1.3 CDTI failing at 60,000 miles. But car was a used buy so no record of how it had been maintained.
Report of vibration from doors, dashboard and hatchback of pre-registered Vauxhall Corsa bought in June 2017. Has been in for repair 3 times where the doors have been packed then both doors replaced and the dash taken off. The dealer stated they would replace the car if he wasnt happy with it. These vibrations were still there after the works carried out. Owner then told its a characteristic. Dealer then emailed to state it would not replace the car under rejection and neither would Vauxhall support it.
Report of clutch failing on 2015 Vauxhall Corsa 1.2SXi at 10,250 miles.

Use the failure ranking as a pre-test checklist or a haggling lever. Treat the headline pass rate as a fleet-wide trend, not a guarantee on any individual car.
If you own a Corsa Ultimate Nav Turbo Auto and your last MOT looked nothing like the ranked failures above, that's normal — individual cars vary widely. The ranking shows the patterns testers flag most often across the country.
