Ive just had a water leak problem, back passenger footwell filling with water everytime it rained but no visible signs of where it was coming from. I bought the car as an ex ford owed with 1800 miles on clock. Apparently this water leak was a known fault on the 58 plates, I have a Fiesta Style. The leak was due to insufficient sealant on the A post. Even though I took out an extended warranty, guess what, water leaks arent covered after the first 12 months. However, due to my very helpful service manager, customer relations have agreed to foot 75% of the bill and my dealer is going to cover the rest. This is about my sixth Ford and my fourth Fiesta but its really put me off.
