Well, it would seem that the discs on my EcoSport will need changing every 6,500 miles or so. (Error in my previous post, changed at 6,400 not 4,600 miles.)
Dealer said that pads are not changed under warranty so can't do anything about the suggestions made here. The dealer also hinted that there might be an issue that they are aware of but didn't seem to want to tell me about it!
I work for the company in the UK and still don't understand why customers are treated like idiots. We told them what the problem was but they didn't want to know, had to follow the "process".
Love the car but two warranty visits in 11 months?
