Expert verdict
Brakes make up 29.5% of everything recorded on the 2012 Infiniti Ex, against 20.9% nationally — 8.6 points above. Have the discs and pads measured rather than glanced at, and ask whether the handbrake holds on a slope.

Cars of this age and mileage average 77.2%, so this figure is 4.6 points ahead of what its age and mileage predict. On a first attempt, before any retests, the figure drops to 78.9%. The median 2012 Infiniti Ex in this dataset had covered 88,145 mi.
Pass rates also shift with the test month: tests recorded October–March passed 84.1% of the time, April–September 79.5%.
The single most recorded failure item is "Registration plate lamp(s) inoperative in the case of multiple lamps or light sources", noted on 12.50% of tests.
Figures count every completed test on this vehicle-year in the dataset, including retests. See methodology for the exact definition.

Regions come from the postcode area recorded at the test station. Areas on region borders are assigned to the region with the majority of their population.
Everything a tester recorded on this vehicle, grouped into the inspection sections that produced it. The notch on each bar is the national share, so you can see at a glance whether this car is unusual or just ordinary.
A test can record several items, so these percentages do not add up to 100%. The exact strings, with prices, are in the full DVSA record at the bottom of this page.
Before your test
These are not generic tips — they are the faults recorded most often on this exact model, rewritten as things you can check yourself. All three take about ten minutes and cost nothing.
Check the lights 12.5% of tests
“registration plate lamp(s) inoperative in the case of multiple lamps or light sources”
Switch everything on and walk round the car: both headlamps on dip and main, every indicator, both brake lights, reverse, fog and the two number-plate lamps. A bulb is a few pounds and a five-minute job.
Check the suspension joints 2.3% of tests
“ball joint excessively worn”
With the car parked on level ground, rock the top of each front wheel in and out while someone watches the suspension arm. Clunks, or rubber boots split and greasy, are what testers record here.
Check the coil springs 2.3% of tests
“coil spring fractured or broken”
Look up inside each wheel arch with a torch, all the way round the spring. A snapped spring usually breaks at the very bottom coil, where a quick glance will not reach.
Shares are the proportion of tests on this vehicle that recorded the item, so they overlap: one test can record several.
Across the 10 items that are recorded most often on this model, the average repair comes to £23–£68 — and 61% of those repairs are parts that cost under £30.
Estimates from typical UK parts prices, weighted by how often each item appears in 88 MOT tests on this vehicle. They exclude diagnostics, retest fees and garage labour where the part is a DIY fit, and they are not figures from the DVSA dataset. Older and higher-mileage examples cost more than the average.

3 model years on record, from 2010 to 2012. Across them the pass rate runs from 80.4% to 81.8% — a spread of 1.4 points. The bar under each year is the item that failed it most often.
Colour is the pass rate on a fixed scale, so a block means the same thing on any model. Each year links to its own page with the full fault breakdown.
The raw pass rate mostly measures age. The year comparison adds the like-for-like figure, the mileage bands and the repair bill.
Closest pass rates among 2012 cars with at least 2,000 tests, so a small sample cannot flatter itself into the list. See the full rankings: best and worst MOT pass rates.
Shares of the 176 individual items recorded on this vehicle, and the same share across all cars nationally. A single test can record several items, so a row is not a percentage of tests.

Severity is as recorded: Major and Dangerous fail the test outright; Minor and Advisory do not. Costs are estimates from typical UK parts prices — see how they are built.
Advisories are the early warnings — the same parts a year or two before they fail. Reading them is how you tell a car that has been maintained from one that has been patched.
