2014 Vauxhall Cascada — MOT failures & pass rate
Across 4,255 MOT tests, the 2014 Vauxhall Cascada recorded an 82.3% pass rate. Coupes & convertibles of a similar age fail 13.2% of the time, so this is 4.6pp worse than the group it competes with. Failures cluster in suspension, tyres and lighting & signalling.
What the MOT record shows
No single area dominates — suspension (8.4%) and tyres (5.5%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are coil spring, brake pads and headlamp aim — coil spring alone was recorded 386 times.
A 150k+ example is materially riskier than a 0-30k one: 29.4% versus 14.1%.
Fuel type barely separates them — petrol fails 17.3% of the time against 18.1% for diesel.
Tyres is the most common advisory, noted on 26.8% of tests — work that passed today but is likely due soon.

What to check before buying a 2014 Cascada
The failure pattern for this year is specific enough to inspect against: suspension accounted for 8.4% of tests. Start there.
- Suspension (8.4% of tests): Worn drop links, bushes, springs or shocks — listen for knocks over bumps and check for uneven tyre wear. Typical repair: £150–£450 per corner.
- Tyres (5.5% of tests): Usually a quick, known-cost fix, but check tread, age and uneven wear (which can hint at alignment or suspension issues). Typical repair: £50–£120 per tyre.
- Lighting & signalling (4.6% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
