2018 Lexus Rc — MOT failures & pass rate
2,132 MOT tests on the 2018 Lexus Rc are in this dataset, and 93.6% of them passed. That is 4.6 percentage points better than all cars of a similar age, which fail at 11.0%. Failures cluster in tyres, visibility and lighting & signalling.
What the MOT record shows
No single area dominates — tyres (4.4%) and visibility (2.6%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are wipers, tread depth and headlamp aim — wipers alone was recorded 71 times.
A 60-90k example is materially riskier than a 0-30k one: 12.4% versus 4.2%.
Advisories point at the next bill rather than this one: tyres was flagged on 21.6% of tests without failing them.
The trend is worsening — 5.4% of tests failed in 2021 against 8.2% 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 Rc
On a 2018 Rc, tyres is what the MOT record says goes wrong most — it appeared in 4.4% of tests. Check these areas before you commit.
- Tyres (4.4% 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.
- 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.
- Lighting & signalling (1.1% 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.
