2017 Lexus Gs — MOT failures & pass rate
Across 1,984 MOT tests, the 2017 Lexus Gs recorded a 95.0% pass rate. Against executive cars of a similar age (11.6% fail rate), the 2017 Gs comes out 6.6pp better. Failures cluster in tyres, visibility and lighting & signalling.
What the MOT record shows
No single area dominates — tyres (3.2%) and visibility (2.5%) 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 49 times.
A 150k+ example is materially riskier than a 0-30k one: 11.8% versus 3.0%.
Advisories point at the next bill rather than this one: tyres was flagged on 19.9% of tests without failing them.

What to check before buying a 2017 Gs
On a 2017 Gs, tyres is what the MOT record says goes wrong most — it appeared in 3.2% of tests. Check these areas before you commit.
- Tyres (3.2% 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 (2.5% 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 (2.0% 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.
