Common initial failure categories
These are the items that most often caused a MG ZS to fail its first test, with what each one usually means for a buyer.
- Headlamps — 4.1% of tests. A headlight fault, from a blown bulb to a failed unit.
- Mechanical Brake Components — 4% of tests. Worn discs, pads or callipers. Routine wear, but it should be priced into the deal.
- Brake Performance — 3.7% of tests. The brakes underperformed on the rolling road. Expect brake work rather than an adjustment.
- Condition — 2.7% of tests. Corrosion, damage or wear on a tested component. Worth seeing in person, as the cost ranges from trivial to structural.
- Headlamp Aim — 2.7% of tests. Headlights pointing too high or low. Cheap to adjust, and common on every make.
- Exhaust Emissions — 2.5% of tests. The car exceeded its emissions limits. Can be a sensor or a service, but on a diesel it can also mean an expensive filter or catalyst.
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.
How many MG ZS are left?
At the end of 2026 Q1, DfT recorded 133,658 licensed and 3,320 SORN vehicles in the MG ZS generic-model group.
