What the MOT record shows

No single area dominates — tyres (2.5%) and lighting & signalling (0.9%) 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 20 times.

Tyres is the most common advisory, noted on 13.9% of tests — work that passed today but is likely due soon.

What to check before buying a Lexus Nx 350H

Tyres (2.5% 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 (0.9% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
Visibility (0.4% 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.
