2018 Lexus Lc — MOT failures & pass rate
702 MOT tests on the 2018 Lexus Lc are in this dataset, and 96.4% of them passed. All cars of a similar age fail 11.0% of the time, so this is 7.4pp better than the group it competes with. Failures cluster in tyres, lighting & signalling and visibility.
What the MOT record shows
No single area dominates — tyres (3.3%) and lighting & signalling (2.9%) 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 27 times.
Advisories point at the next bill rather than this one: tyres was flagged on 14.5% of tests without failing them.
The trend is worsening — 3.6% of tests failed in 2021 against 6.5% 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.

What to check before buying a 2018 Lc
On a 2018 Lc, tyres is what the MOT record says goes wrong most — it appeared in 3.3% of tests. Check these areas before you commit.
- Tyres (3.3% 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 (2.9% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Visibility (1.0% 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.
