i had the same thing with a citroen c4 grandpicasso had it 7 days and picked up 2 screws one of which was right on the join of thetyre wall so it couldnt be repaired it had to be replaced. major argument with mota as they just wanted them to replace it with the cheapest option rather than the type the car came with.
they agreed eventually but it was a pain. kwikfit were fine very efficient.
