Most common faults at 22 years
These figures cover all Ford Ka MOTs at 22 years: cars first used 2000 to 2003, tested 2022 to 2025 (n=2,986). The list uses every first-use year so it has enough tests. Wear items (tyres, brake pads, wipers, bulbs) say more about upkeep than about the design.
MOT fail items
| Fail item | Per 100 MOTs | All cars |
|---|---|---|
| Component mounting prescribed areas: prescribed area excessively corroded significantly reducing structural strength | 13.5 | 3.5 |
| Suspension arm bush worn | 6.8 | 1.7 |
| Seat belt prescribed areas: prescribed area strength or continuity significantly reduced | 6.4 | 1.3 |
| Wipers not clearing screen Wear | 5.1 | 3.5 |

Per 100 of the MOTs above (n=2,986). A test with two items counts once for each.

Fuel type at 22 years

| Fuel | Share of tests | MOT fail rate | Tests (n) | All cars, same fuel | Median mileage |
|---|---|---|---|---|---|
| Petrol | 100.0% | 49.0% | 2,986 | 40.6% | 49,318 miles |
Car tax rules for a 2003 car
- Cars first registered from 1 March 2001 to 31 March 2017 are taxed by CO2 emissions band, from band A (the lowest emissions) to band M. The band is set by the CO2 figure on the V5C logbook.
These are the rules, not the amount for a specific car. Car tax check
ULEZ and clean air zones
- Many petrol cars first registered from 2001 to 2005 already meet Euro 4, but not all of them. For a 2003 petrol car the Euro standard of that car decides.
- The clean air zones in Birmingham and Bristol use the same Euro 4 petrol and Euro 6 diesel standards. The low emission zones in Scotland use them too, but enforce them with fines, not a daily charge.
The Euro standard of the car decides, not the year alone. ULEZ checker
