Daihatsu Cuore MOT Failures

An analysis of 6,992 real DVSA MOT tests on the Daihatsu Cuore — what fails, how often, and how that compares to every other car on UK roads. Generations covered: L701 (1998–2007).

Where the Daihatsu Cuore fails its MOT

The single biggest MOT failure point on the Daihatsu Cuore is seat mounting fault — this model is 104 times more likely to fail on this item than the average car on UK roads. That makes it an extreme outlier for anyone buying or owning this model. Across 6,992 MOT tests, 6.93% of all Daihatsu Cuore tests recorded this as a failure.

Other notable weak points include structural corrosion (100x the fleet average), abs fault (79x the fleet average), suspension joint dust cover severely deteriorated (39x the fleet average), and vehicle structure corroded to the extent that t... (70x the fleet average). These ratios compare the Daihatsu Cuore's failure rate on each item against the national average for all cars tested — a ratio of 10x means this model fails ten times more often than a typical car.

The failures span 4 categories: Seatbelts & Airbags, Bodywork, Suspension, Brakes. If you're inspecting a Daihatsu Cuore before purchase, these are the areas to focus on — and if any have been flagged as advisories on a previous MOT, they're likely to become failures in the near future.

How failures change with mileage

The Daihatsu Cuore's weak points shift as the car covers more miles. Understanding these patterns helps you know what to expect — and what to budget for — at each stage of ownership.

Under 60,000 miles

At this mileage, most failures are either design-related or caused by age rather than wear. Components like bushes and drop links may not have been replaced yet, and original-fit parts can deteriorate even on low-mileage cars that spend a lot of time sitting.

For the Daihatsu Cuore specifically, the DVSA data shows the most common failures at this mileage are seat mounting fault (104x the average) and structural corrosion (100x). abs fault (79x) and vehicle structure corroded to the extent that t... (70x) also appear frequently.

60,000 to 100,000 miles

This is where routine wear items start to show up. Brake components, tyres, and exhaust parts have done serious work by this point. Cars that have been well serviced will show fewer of these failures — this mileage band is where good maintenance really separates the well-kept from the neglected.

For the Daihatsu Cuore specifically, the DVSA data shows the most common failures at this mileage are structural corrosion (38x the average) and seat mounting fault (35x). vehicle structure corroded to the extent that t... (34x) and abs fault (32x) also appear frequently.

The shift from seat mounting fault at lower mileages to structural corrosion at higher mileages is typical — early failures tend to be design or factory-related, while high-mileage failures reflect accumulated mechanical wear. A car that's been well maintained will usually dodge the worst of both.

Known issues beyond the MOT

An MOT only tests roadworthiness at a single point in time — it won't catch developing faults, intermittent problems, or issues that haven't yet reached the failure threshold. These are the issues that Daihatsu Cuore specialists and owners flag most frequently, drawn from manufacturer technical bulletins, workshop data, and verified owner reports.

Structural corrosion reducing body rigidity (L701) Dangerous

The Cuore's lightweight construction uses thin steel panels that are particularly vulnerable to through-corrosion in structural areas. Affects L701; typical independent garage repair cost is £800–£2,000.

Subframe mounting point corrosion (L701) Dangerous

The mounting points where the front subframe attaches to the body structure are particularly vulnerable to corrosion on the Cuore. Affects L701; typical independent garage repair cost is £1,200–£2,500.

Brake system imbalance (L701) Major

Brake imbalance across an axle occurs at 27.6 times the fleet average on the Cuore, where one brake applies significantly less force than its partner on the same axle. Affects L701; typical independent garage repair cost is £150–£400.

CV joint boot deterioration (L701)

The rubber boots protecting the constant velocity joints on the driveshafts deteriorate at 35.5 times the fleet average rate on the Cuore. Affects L701; typical independent garage repair cost is £80–£150.

What to check before buying a Daihatsu Cuore

Based on the MOT failure data and known issues above, here's what to prioritise when inspecting a Daihatsu Cuore:

Seatbelts & Airbags — check for seat mounting fault. Bodywork — check for structural corrosion, vehicle structure corroded to the extent that t..., transmission shaft constant velocity joint boot.... Suspension — check for abs fault, suspension joint dust cover severely deteriorated.

Beyond the MOT items, ask specifically about structural corrosion reducing body rigidity and subframe mounting point corrosion. These won't show up on a standard MOT but can be expensive to fix — repairs start from £800. A specialist pre-purchase inspection is worth the investment on this model.

Always check the car's full MOT history for patterns — recurring advisories often become failures within 12 months. And verify the service history to confirm maintenance has been kept up to schedule. Enter any reg into our free car check to see the complete picture.
