Reva G.Wiz MOT pass rate & common failures
Across 9 model years and 1,083 tests, the Reva G.Wiz passes its MOT 82.5% of the time. All cars of a similar age fail 26.6% of the time, so this is 9.1pp better than the group it competes with. Its most common failure areas are lighting & signalling, suspension and brakes.
What the MOT record shows
One area stands out: lighting & signalling, recorded in 17.4% of tests against 5.9% for the next-worst category.
At component level the recurring items are headlamp aim, headlamp and service brake performance — headlamp aim alone was recorded 101 times.
Suspension is the most common advisory, noted on 21.6% of tests — work that passed today but is likely due soon.

What to check before buying a Reva G.Wiz
- Lighting & signalling (17.4% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (5.9% 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.
- Brakes (4.9% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
