2021 Lexus Ct — MOT failures & pass rate
The 2021 Lexus Ct passed 95.9% of its 629 recorded MOT tests. Small family cars of a similar age fail 8.2% of the time, so this is 4.1pp better than the group it competes with. Failures cluster in visibility, tyres and lighting & signalling.
What the MOT record shows
No single area dominates — visibility (2.4%) and tyres (1.9%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are wipers, headlamp aim and tread depth — wipers alone was recorded 16 times.
A 60-90k example is materially riskier than a 0-30k one: 15.4% versus 0.4%.
Advisories point at the next bill rather than this one: tyres was flagged on 16.5% of tests without failing them.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.
| # | Category | % of tests with advisory | Tests |
|---|---|---|---|
| 1 | Tyres | 16.5% | 104 |
| 2 | Brakes | 6.8% | 43 |
| 3 | Other defects | 5.4% | 34 |
| 4 | Visibility | 4.1% | 26 |
| 5 | Road wheels | 0.8% | 5 |
| 6 | Steering | 0.3% | 2 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.
| Mileage band | Tests | Fail rate |
|---|---|---|
| 0-30k | 263 | 0.4% |
| 30-60k | 322 | 5.3% |
| 60-90k | 39 | 15.4% |
Failure rate by age
Trend over time
| Dataset year | Tests | Fail rate |
|---|---|---|
| 2024 | 306 | 4.3% |
| 2025 | 294 | 4.1% |
What to check before buying a 2021 Ct
On a 2021 Ct, visibility is what the MOT record says goes wrong most — it appeared in 2.4% of tests. Check these areas before you commit.
- Visibility (2.4% 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.
- Tyres (1.9% 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 (1.8% 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.
