2015 Renault Grand Scenic — MOT failures & pass rate
9,031 MOT tests on the 2015 Renault Grand Scenic are in this dataset, and 77.8% of them passed. Against MPVs of a similar age (17.1% fail rate), the 2015 Grand Scenic comes out 5.0pp worse. Failures cluster in lighting & signalling, suspension and tyres.
What the MOT record shows
Lighting & signalling dominates the failure mix at 14.1% of all tests — 7.2 points clear of suspension, so it is the first thing to check.
At component level the recurring items are stop lamp, track rod end and wipers — stop lamp alone was recorded 705 times.
A 150k+ example is materially riskier than a 0-30k one: 19.7% versus 11.3%.
Advisories point at the next bill rather than this one: tyres was flagged on 29.6% of tests without failing them.
The trend is worsening — 17.0% of tests failed in 2021 against 25.2% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2015 Grand Scenic
On a 2015 Grand Scenic, lighting & signalling is what the MOT record says goes wrong most — it appeared in 14.1% of tests. Check these areas before you commit.
- Lighting & signalling (14.1% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (6.9% 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.
- Tyres (6.0% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
