2015 Lexus Ct — MOT failures & pass rate
Across 19,057 MOT tests, the 2015 Lexus Ct recorded a 91.4% pass rate. That is 6.9 percentage points better than small family cars of a similar age, which fail at 15.6%. Failures cluster in tyres, lighting & signalling and visibility.
What the MOT record shows
No single area dominates — tyres (5.0%) and lighting & signalling (4.7%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are headlamp, wipers and tread depth — headlamp alone was recorded 475 times.
Condition tracks the odometer closely. Failures run at 3.0% in the 0-30k band and 11.1% in the 150k+ band, a 8.1-point spread — more than double.
Tyres is the most common advisory, noted on 22.5% of tests — work that passed today but is likely due soon.
The trend is worsening — 6.8% of tests failed in 2021 against 10.7% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2015 Ct
The failure pattern for this year is specific enough to inspect against: tyres accounted for 5.0% of tests. Start there.
- Tyres (5.0% 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 (4.7% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Visibility (2.6% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
