Common initial failure categories
These are the items that most often caused a Mazda 6 to fail its first test, with what each one usually means for a buyer.
- Brake Performance — 6.1% of tests. The brakes underperformed on the rolling road. Expect brake work rather than an adjustment.
- Suspension Arms — 4.9% of tests. Worn arms or bushes. A common age-related repair that affects handling and tyre wear.
- Position Lamps — 4.6% of tests. A side or tail light out. Usually a bulb.
- Mechanical Brake Components — 4% of tests. Worn discs, pads or callipers. Routine wear, but it should be priced into the deal.
- Condition — 3.8% of tests. Corrosion, damage or wear on a tested component. Worth seeing in person, as the cost ranges from trivial to structural.
- Headlamp Aim — 3.5% of tests. Headlights pointing too high or low. Cheap to adjust, and common on every make.
What this does and does not tell you
A pass rate describes how a population of cars behaved on test day. It says nothing about how one car was driven, serviced or repaired, and an MOT does not cover the engine, clutch or gearbox at all.
Use it to know what to look for: if tyres and brakes dominate the list, price those in; if corrosion or suspension appears, get underneath the car. Then check the individual vehicle — its MOT history shows whether these same items have been advised year after year, and its mileage record shows whether the reading is consistent.
