Ford ST MOT reliability

Ford STs passed their MOT first time 40% of the time across 5 tests in 2025.

These figures come from only 5 MOT tests. With so few cars, a single pass or fail changes the percentages a lot, so treat them as a rough guide rather than a true average.

Pass rate by year of first registration

Older cars fail more often, so compare a car with others of the same age. Years with very few MOTs can show extreme pass rates, even 0% or 100%, so give more weight to years with more tests.
