Piper Gt MOT failure rate
What a Piper Gt fails its MOT on, from real DVSA test data, and the part that resolves each item.
Based on 32 MOT tests in DVSA data.
We hold 32 MOT tests for the Piper Gt in the DVSA data. That is a smaller sample than our high-volume models, so treat these figures as indicative rather than definitive.
On what we have, about 12.5% fail, most often on lamps & electrical, visibility/wipers, brakes. For a precise picture of your own car, use the registration check on the home page. Confirm any part against your registration or VIN before buying.
What it fails on, and why
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.
Visibility failures include torn or smearing wiper blades, a washer jet that does not reach the screen, and chips or cracks in the driver's swept area. Blades and washer fluid are quick, cheap fixes.
Brake failures cover worn pads and discs, an imbalance between wheels, corroded or scored discs, or a binding caliper. Braking efficiency is measured on a rolling road, so a spongy or pulling brake shows up as a low reading.
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. These are the usual parts; confirm the exact fitment against your registration or VIN before buying.
