Lexus Lc MOT pass rate & common failures
2,092 MOT tests on the Lexus Lc (2017–2023) give it a 96.0% pass rate. That is 7.2 percentage points better than all cars of a similar age, which fail at 11.2%. Its most common failure areas are tyres, lighting & signalling and visibility.
What the MOT record shows
No single area dominates — tyres (3.4%) and lighting & signalling (2.1%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are headlamp aim, tread depth and wipers — headlamp aim alone was recorded 60 times.
A 60-90k example is materially riskier than a 0-30k one: 11.5% versus 2.8%.
Fuel type barely separates them — petrol fails 3.8% of the time against 4.2% for hybrid.
Tyres is the most common advisory, noted on 15.3% of tests — work that passed today but is likely due soon.

What to check before buying a Lexus Lc
- Tyres (3.4% 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 (2.1% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Visibility (0.7% 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.
