Renault Grscenic MOT pass rate & common failures
634 MOT tests on the Renault Grscenic (2010–2015) give it a 69.9% pass rate. That is 12.0 percentage points worse than all cars of a similar age, which fail at 18.1%. Its most common failure areas are lighting & signalling, body, structure & corrosion and suspension.
What the MOT record shows
Lighting & signalling dominates the failure mix at 17.0% of all tests — 4.6 points clear of body, structure & corrosion, so it is the first thing to check.
At component level the recurring items are joints, stop lamp and coil spring — joints alone was recorded 96 times.
Condition tracks the odometer closely. Failures run at 23.5% in the 30-60k band and 33.3% in the 150k+ band, a 9.9-point spread.
Advisories point at the next bill rather than this one: tyres was flagged on 31.1% of tests without failing them.
The trend is worsening — 30.3% of tests failed in 2021 against 32.4% in 2025, the usual pattern as a fleet ages.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.

What to check before buying a Renault Grscenic
- Lighting & signalling (17.0% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Body, structure & corrosion (12.5% of tests): The one to take seriously on older cars — corrosion to structural areas can be costly and is an MOT failure. Typical repair: £200–£1,500+.
- Suspension (10.7% 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.
