The 2003 Suzuki Alto MOT pass rate is 67.5% of its MOT tests — 5.1 points behind what its age and mileage predict. Suspension is the biggest single reason it fails, at 26.7% of what testers record.

Expert verdict
Body & chassis accounts for 12.1% of everything recorded on the 2003 Suzuki Alto, against 5.6% nationally — 6.5 points above. Suspension is still the single largest share at 26.7%, but at 21.0% nationally that one is ordinary. Look underneath for corrosion near the jacking points and suspension mounts; surface rust is normal, flaking metal is not.

Cars of this age and mileage average 72.6%, so this figure is 5.1 points behind what its age and mileage predict. On a first attempt, before any retests, the figure drops to 56.3%. The median 2003 Suzuki Alto in this dataset had covered 53,645 mi.
Pass rates also shift with the test month: tests recorded October–March passed 67.7% of the time, April–September 67.2%.
The single most recorded failure item is "Registration plate lamp(s) inoperative in the case of multiple lamps or light sources", noted on 7.55% 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 7.5% 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 5.3% of tests
“ball joint dust cover severely deteriorated”
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 brake pipes 4.0% of tests
“rigid brake pipes excessively corroded”
Brake pipes run under the car, usually in front of the rear wheels. Flaking or crusty metal is what fails; a light dusting of surface rust does not. Worth asking a garage to look while it is on a ramp.
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 £40–£112 — and 29% of those repairs are parts that cost under £30.
Estimates from typical UK parts prices, weighted by how often each item appears in 1,616 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.

13 model years on record, from 2001 to 2015. Across them the pass rate runs from 66.4% to 83.1% — a spread of 16.7 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 2003 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.

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.

67.5% of the 1,616 2003 Suzuki Alto tests in this dataset passed, against a national average of 72.6% for cars first used in 2003. First-attempt pass rate: 56.3%.
The three most recorded items are registration plate lamp(s) inoperative in the case of multiple lamps or light sources (7.55%), service brake imbalance across an axle (6.68%), joints constant velocity boot split or insecure, no longer prevents the ingress of dirt (6.44%). Percentages are the share of tests on this vehicle that recorded the item.
Yes. Cars under 30,000 miles passed 72.0% of the time, falling to 70.6% for those over 120,000 miles. The median 2003 Suzuki Alto in this dataset had covered 53,645 mi.
Tests recorded in the winter months (October–March) passed 67.7% of the time; summer months (April–September) passed 67.2%. Brakes, tyres and lights are tested harder in bad weather, but the difference is small on most models.
