It does affect the Mk2 model Ka, which I have, and has 5-spoke 16"alloy wheels, in fact I'm going to Dagenham Motors tonight for the 3rd time to have it out with them over my buckled alloys and I've only owned the car for a month! I had the 1.4 petrol Fiesta Zetec with 8-spoke 15" wheels from October 09-10 and never had a single problem with the car, changed to the diesel Ka to save money on travel (I do a lot of motorway miles) and it's been a nightmare since day one. I took it back a week after having it because the car was pulling to the left, mechanic phones me within an hour and tells me both front alloys are buckled and the inside edge of the tires also need replacing as a result. I said I'd only bought it last week and subsequently got a callback in an hour from the rep who sold me it saying that they'd replace one wheel for free and the tracking was indeed out, but that the other wheel and tires were fine - so who's telling the truth right? Another week passes and I take it back because the car still pulls to the left, they say the tracking is out again, try to charge me to fix it (I refused and they accepted as it was an ongoing problem), but it still isn't right. Changing to this car was a bad idea, can't wait to change back to the Fiesta. I don't think it's a coincidence that almost all the used Mk7 Fiestas available on the Dagenham Motors website are Titanium models with the alloy wheels you're all describing. Hoping I won't get modded for my kind of-on, kind of-off topic reply, long-time reader first-time poster!
