When I brought my FX a dash replacement just two day before my warranty was to expire the dealership listed off a bunch of other repairs that were common problems with the car and asked if I wanted them "fixed". Since it was no cost to me and some of them might act up next week I had them do all the list.
Sounds more like a dealer scamming the warranty program to me. Nice way to drive up costs for the manufacturer. Wonder who pays for that in the long run...
