A relative of mine had the pre-99 Ford 4.6L intake manifold crack problem. Ford wouldn’t fix it because the engine was in a Mustang and he wasn’t a fleet buyer. Ford WOULD fix the problem if it was in a Grand Marquis or Crown Vic and it was part of a fleet... but if you had a Mustang, truck, Explorer, or anything else that had the 4.6, you were SOL.
He had to sue Ford to get them to fix the problem.
Here’s a discussion of what happened: http://www.flamingfords.info/manifoldSettlement.html
The website seems to exaggerate a good deal (don't have ANY Ford with a cruise control anywhere near where you sleep, even if it's not one of the recalled models - Ford electrical engineers no good, etc.) but that's normal for internet crusades. When you have a hammer, everything looks like a nail.
Similar websites exist for almost every make and model out there . . . e.g. GMLemonCars.com, the first one I found.
