ECU ingested water after 13 months. Replaced under warranty.
Downpipe heatshield rattles. Replaced under warranty.
Plastic runner thing in the driver's door electric window broke under normal use. Out of warranty. Would not sell the plastic part, forced to buy a complete winder unit with a motor for £160.
Sunroof rattles.... dealer could not sort it out.
A/C stopped working, faulty seals and leaking gas, out of warranty (just).
Aside from the problems above, it's a great car and now there are lots of aftermarket accessories available, like engine mods, body kits, suspension upgrades etc. SJB Sport seem to be the tuning people for Seat.
Am waiting for the new Cordoba 1.8T.
What a surprise!
I too had a rattling heatsheild after only 2000 miles. Been to dealer to either be repaired or replaced 6 or 7 times (latest dealer theory was a stone trapped in exhaust!!) but starting to rattle again after 35000 miles.
As for the plastic runner on the electric window, mine too broke resulting in the window falling down between the door skin. luckily I still had 10 days warranty left.
I know I should sell the car before I loose too much money, but I will be sad to see a great car go.
