Probably not what you want to hear, but - when this happened to me - there had been no recall issued (still hasn't as far as I know, it's probably not regarded as safety related) and I believe that it was decided by Mazda to only "fix this issue if it occurs". Mine was under warranty at the time fortunately so was sorted straightaway. FYI, the CX5 doesn't even appear on the DVSA recalls list
http://www.dft.gov.uk/vosa/apps/recalls/default.aspThe net result of that, if true, is that there are a lot of early models changing hands now with an inherent problem which may or may not have been sorted. As knowledge of this problem becomes known, these vehicles are going to become unsaleable unless Mazda agree to sort it irrespective of age or warranty status. If a good solicitor got involved, a group action on behalf of affected owners might be the way forward?
