Hyundai Atoz MOT pass rate & common failures
1,836 MOT tests on the Hyundai Atoz (1998–2016) give it a 68.6% pass rate. That is 5.0 percentage points worse than all cars of a similar age, which fail at 26.4%. Its most common failure areas are lighting & signalling, suspension and body, structure & corrosion.
What the MOT record shows
No single area dominates — lighting & signalling (16.3%) and suspension (14.0%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are joints, headlamp aim and service brake performance — joints alone was recorded 145 times.
A 120-150k example is materially riskier than a 0-30k one: 31.6% versus 25.9%.
Suspension is the most common advisory, noted on 38.1% of tests — work that passed today but is likely due soon.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.

What to check before buying a Hyundai Atoz
- Lighting & signalling (16.3% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (14.0% 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.
- Body, structure & corrosion (13.4% of tests): The one to take seriously on older cars — corrosion to structural areas can be costly and is an MOT failure. Typical repair: £200–£1,500+.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
