2015 Renault Twizy — MOT failures & pass rate
371 MOT tests on the 2015 Renault Twizy are in this dataset, and 81.1% of them passed. Against all cars of a similar age (16.2% fail rate), the 2015 Twizy comes out 2.7pp worse. Failures cluster in brakes, lighting & signalling and visibility.
What the MOT record shows
One area stands out: brakes, recorded in 12.4% of tests against 8.6% for the next-worst category.
At component level the recurring items are switch, service brake performance and rbt (sp) — switch alone was recorded 20 times.
Brakes is the most common advisory, noted on 26.7% of tests — work that passed today but is likely due soon.
The trend is improving — the fail rate fell from 22.4% in 2021 to 19.1% in 2025, as the worst-kept examples leave the fleet.

What to check before buying a 2015 Twizy
The failure pattern for this year is specific enough to inspect against: brakes accounted for 12.4% of tests. Start there.
- Brakes (12.4% of tests): Pads/discs are routine wear; binding, imbalance or corroded pipes are more serious — test for pulling under braking. Typical repair: £100–£350 per axle.
- Lighting & signalling (8.6% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Visibility (3.5% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
