2011 Renault Grand Modus — MOT failures & pass rate
5,294 MOT tests on the 2011 Renault Grand Modus are in this dataset, and 71.2% of them passed. All cars of a similar age fail 23.1% of the time, so this is 5.7pp worse than the group it competes with. Failures cluster in suspension, lighting & signalling and steering.
What the MOT record shows
One area stands out: suspension, recorded in 18.4% of tests against 15.4% for the next-worst category.
At component level the recurring items are coil spring, position lamp and track rod end — coil spring alone was recorded 721 times.
Mileage is the strongest signal on the record: 19.1% of 0-30k cars fail, rising to 27.8% once past 150k.
The petrol cars hold up better: 27.1% fail against 29.5% for diesel, a 2.4-point gap across 5,291 tests.
Tyres is the most common advisory, noted on 28.5% of tests — work that passed today but is likely due soon.
The trend is worsening — 27.7% of tests failed in 2021 against 30.1% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2011 Grand Modus
The failure pattern for this year is specific enough to inspect against: suspension accounted for 18.4% of tests. Start there.
- Suspension (18.4% 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.
- Lighting & signalling (15.4% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Steering (6.1% of tests): Play, leaks or worn track rod ends — affects handling and is a safety item. Typical repair: £150–£500.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
