2013 Lexus Is 300H F — MOT failures & pass rate
Across 1,867 MOT tests, the 2013 Lexus Is 300H F recorded an 89.1% pass rate. That is 9.1 percentage points better than all cars of a similar age, which fail at 20.1%. Failures cluster in tyres, lighting & signalling and visibility.
What the MOT record shows
No single area dominates — tyres (6.3%) and lighting & signalling (4.5%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are headlamp aim, headlamp and tread depth — headlamp aim alone was recorded 53 times.
Mileage matters less than usual here: the 2013 Is 300H F fails 8.0% of the time in the 30-60k band and 10.4% at 150k+, a spread of only 2.4 points.
Tyres is the most common advisory, noted on 24.8% of tests — work that passed today but is likely due soon.
The trend is worsening — 9.6% of tests failed in 2021 against 12.2% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2013 Is 300H F
The failure pattern for this year is specific enough to inspect against: tyres accounted for 6.3% of tests. Start there.
- Tyres (6.3% 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 (4.5% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
