Tom-
It sounds like you have a Polybutylene water pipe system-I know nothing about a “recall” per se- but it was part of a very large class action lawsuit that has been ongoing for some time now-with several manufacturers involved-most of them are major oil companies (Shell & Texaco… I think- this was 6 years ago). The name of the manufacturer should be on the pipe itself & you can probably research from there. If you don’t particularly feel like ripping into your walls, going under your house, or into your attic, Try researching the name “Quest” or “Qest” (I can’t remember How it’s spelled). As far as repairing the pipe goes… fittings & replacement pipe are sometimes hard to come by since it is a discontinued product (due to the fact that it was a poor system that was prone to leaks) but, I have seen crimp rings & fittings at the Home Depot from time to time. A repipe is recommended & with some of the new products available (Wirsbo & Plumb-pex polyethylene systems)-repiping the house yourself…or even hiring a plumbing contractor would be fairly cheap & easy). As far as suing the manufacturer goes, you may be successful.
good luck
