2015 Lexus Gs — MOT failures & pass rate
The 2015 Lexus Gs passed 94.1% of its 2,047 recorded MOT tests. That is 8.2 percentage points better than executive cars of a similar age, which fail at 14.1%. Failures cluster in tyres, visibility and lighting & signalling.
What the MOT record shows
No single area dominates — tyres (4.3%) and visibility (1.8%) 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 brake pads — wipers alone was recorded 47 times.
Mileage matters less than usual here: the 2015 Gs fails 3.7% of the time in the 0-30k band and 3.4% at 150k+, a spread of only 0.3 points.
Advisories point at the next bill rather than this one: tyres was flagged on 20.5% of tests without failing them.

What to check before buying a 2015 Gs
On a 2015 Gs, tyres is what the MOT record says goes wrong most — it appeared in 4.3% of tests. Check these areas before you commit.
- Tyres (4.3% 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.
- Visibility (1.8% 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 (1.6% 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.
