2019 Lexus Nx — MOT failures & pass rate
The 2019 Lexus Nx passed 95.1% of its 19,030 recorded MOT tests. That is 4.5 percentage points better than mid-size SUVs of a similar age, which fail at 9.4%. Failures cluster in tyres, visibility and lighting & signalling.
What the MOT record shows
No single area dominates — tyres (3.4%) and visibility (2.0%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are wipers, headlamp aim and tread depth — wipers alone was recorded 445 times.
Condition tracks the odometer closely. Failures run at 3.1% in the 0-30k band and 12.9% in the 90-120k band, a 9.8-point spread — more than double.
Advisories point at the next bill rather than this one: tyres was flagged on 22.1% of tests without failing them.
The trend is worsening — 3.5% of tests failed in 2021 against 6.1% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2019 Nx
On a 2019 Nx, tyres is what the MOT record says goes wrong most — it appeared in 3.4% of tests. Check these areas before you commit.
- 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.
- Visibility (2.0% 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.
- Lighting & signalling (1.3% 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.
