Question - what kind of defect (whatever the cause) would allow salt water corrosion but not fresh water corrosion? Last August, well before this recall was announced, I had to have a rear wheel bearing replaced due to corrosion and "loss of lubricant". (The grease got hot, melted and flowed out.) Yet the car has not been anywhere near salt water, and I live far enough south that we don't even salt the roads in the winter. (This year, winter happened on February 3 & 4.

)
Comment - I guess I am going to have to talk to my dealer to see if my car is included in the recall. It would be nice to get the bill for the bearing adjusted, and I am curious about the hot cable problem.
Irrelevant but True story about engine fires - long ago and far away, my wife was driving our first car (also a Ford product). She observed that the pale blue paint on the hood was turning brown, and she was starting to look through a definite heat haze in the air. Most odd, as it was the middle of winter (Maryland then, not Georgia!) Anyway, she decided to look into this phenomenon and pulled off the road at the next convenient place. She stopped, got out of the car, and then observed that a major panic attack appeared to be in progress. Everybody in sight was yelling and screaming, and most were running away - FAST! That was when she noticed that (a) she had pulled into a service station, (b) there was now a LOT of smoke coming from the engine area, and (c) she had parked next to the gasoline pumps! Fortunately, the fire station was only two blocks away. Root cause analysis showed that the problem started when the car had received routine service a couple of weeks earlier. The mechanic changed the fuel filter, which threaded into the carburetor body. He got it cross-threaded and rather than redo it again, he just got on it with the proverbial bigger wrench. That resulted in a cracked carburetor body and eventually gasoline leaking onto the exhaust manifold.
(Does everybody remember what a carburetor was? As in a Motorcraft 4-barrel on a 302 engine with dual exhaust!)
