Credov's researched list of the 2 faults the Ford Fiesta-ST is known for (2013–2017), 2 of them serious or costly. Each one says what to look for when you check the car, so you can spot it before you buy. Not every car has these faults: they are the ones worth checking on this model.
What to look for: Ask for a dated receipt showing the timing belt and tensioner have been replaced.
Why it matters: A belt failure on this engine means major, expensive engine damage, so a car with no belt history should be priced to include it.
What to look for: On the drive with the gearbox warm, make quick 1-2 and 3-2 changes and feel for crunching or baulking.
Why it matters: Fixing worn synchros means a gearbox rebuild or a second-hand box, so a crunch found at inspection is worth pricing in before buying.
