It not a brand problem, all have issue's.
But how they look after you ( after sale's Service) say's alot about them. no matter what brand you have.
And yes it's going to cost them. but how much is another matter, ( if a company is going to look after things well ) they will retain the customer. and may get more if the customer tell's others ( how well they looked after them )
But company X does nothing, and leaves everyone out to dry, Could cost them alot more. Just think about it a bit. If you yourself get's looked after well. where is your next purchase coming from.
If they leave you hanging ( where is your purchase going ????????? )
