2018 Lexus Ct — MOT failures & pass rate
14,534 MOT tests on the 2018 Lexus Ct are in this dataset, and 94.2% of them passed. Against small family cars of a similar age (10.4% fail rate), the 2018 Ct comes out 4.6pp better. Failures cluster in tyres, visibility and lighting & signalling.
What the MOT record shows
No single area dominates — tyres (3.8%) and visibility (2.9%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are wipers, tread depth and headlamp aim — wipers alone was recorded 462 times.
A 150k+ example is materially riskier than a 0-30k one: 9.5% versus 2.9%.
Advisories point at the next bill rather than this one: tyres was flagged on 19.9% of tests without failing them.
The trend is worsening — 3.4% of tests failed in 2021 against 8.1% in 2025, the usual pattern as a fleet ages.

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

| 5 | Suspension | 1.1% | 158 |
| 6 | Road wheels | 0.5% | 68 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.

What to check before buying a 2018 Ct
On a 2018 Ct, tyres is what the MOT record says goes wrong most — it appeared in 3.8% of tests. Check these areas before you commit.
- Tyres (3.8% 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.
- Visibility (2.9% of tests): Wipers, washers, mirrors and screen damage — usually inexpensive, but check for chips in the driver's line of sight. Typical repair: £15–£150.
- Lighting & signalling (2.5% 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.
