2014 Chevrolet Aveo — MOT failures & pass rate
Across 835 MOT tests, the 2014 Chevrolet Aveo recorded a 73.8% pass rate. That is 7.0 percentage points worse than superminis of a similar age, which fail at 19.2%. Failures cluster in suspension, lighting & signalling and emissions & environmental.
What the MOT record shows
One area stands out: suspension, recorded in 19.9% of tests against 8.6% for the next-worst category.
At component level the recurring items are coil spring, pins and bushes and ball joint dust cover — coil spring alone was recorded 103 times.
Mileage is the strongest signal on the record: 15.5% of 0-30k cars fail, rising to 28.1% once past 90-120k.
Suspension is the most common advisory, noted on 32.3% of tests — work that passed today but is likely due soon.
The trend is improving — the fail rate fell from 31.4% in 2021 to 24.8% in 2025, as the worst-kept examples leave the fleet.

What to check before buying a 2014 Aveo
The failure pattern for this year is specific enough to inspect against: suspension accounted for 19.9% of tests. Start there.
- Suspension (19.9% 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.
- Lighting & signalling (8.6% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Emissions & environmental (5.1% of tests): More common on older diesels (DPF/EGR) — can be expensive; check for warning lights and smoke. Typical repair: £100–£600.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
