Suzuki Grass MOT failure rate

What a Suzuki Grass fails its MOT on, and the part that fixes each.

What it fails on, and why

Tyres25.0% of failures

Tyres fail for tread below the 1.6mm legal limit across the central three-quarters, uneven or exposed-cord wear, or sidewall damage. The tester inspects all four; a single illegal tyre is a fail.

Other25.0% of failures

This covers a range of smaller items, from a non-working horn to a warning light left on.

Lamps & electrical25.0% of failures

Lighting is the single most common MOT failure and the cheapest to put right. A blown headlight, brake-light or number-plate bulb, a cracked lens, or a headlamp beam that points too high or low will all fail. Most are a two-minute bulb swap.

The parts that fix each

If your car has just failed, you have 10 working days to fix the items and get a free partial retest. Confirm the exact fitment against your registration or VIN before buying.
