My vehicle has had 4 of 6 ignition could fail due to excessive corrosion within a span of months. Failure has resulted in sudden engine failure and hesitations causing the vehicle to lose power unpredictably and forced us to pull over. Subaru of America has refused to repair these components because they are beyond the 3 year warranty period. It is unlikely that four components would all fail similarly without a serious defect in the parts or a design flaw in the automobile. There were two occurrences of this failure- one coil failed in September 2014 and three more failed in December 2015.
