2017 Renault Grand Scenic — MOT failures & pass rate
Across 6,714 MOT tests, the 2017 Renault Grand Scenic recorded an 81.5% pass rate. Against MPVs of a similar age (13.6% fail rate), the 2017 Grand Scenic comes out 4.9pp worse. Failures cluster in lighting & signalling, tyres and suspension.
What the MOT record shows
No single area dominates — lighting & signalling (9.3%) and tyres (7.6%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are stop lamp, headlamp and brake pads — stop lamp alone was recorded 325 times.
A 150k+ example is materially riskier than a 0-30k one: 22.5% versus 12.2%.
Split by fuel, diesel examples fail 2.5pp more often than petrol ones (18.8% vs 16.3%) — worth weighing if you have a choice.
Advisories point at the next bill rather than this one: tyres was flagged on 27.4% of tests without failing them.
The trend is worsening — 13.9% of tests failed in 2021 against 23.0% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2017 Grand Scenic
On a 2017 Grand Scenic, lighting & signalling is what the MOT record says goes wrong most — it appeared in 9.3% of tests. Check these areas before you commit.
- Lighting & signalling (9.3% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Tyres (7.6% 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.
- Suspension (6.5% of tests): Worn drop links, bushes, springs or shocks — listen for knocks over bumps and check for uneven tyre wear. Typical repair: £150–£450 per corner.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
