-Plastic radiator neck fails, leaving nothing for the coolant hose to clamp on to. Only solution is a new radiator. Many replace this before 80K as a preventative measure, since a failure = stranded on the side of the road.
-There seem to be two independent transmission problems. One makes it difficult to shift into gear. The other occurs on cold days, when the detent for 5th gear goes away and the shift lever rests underneath fifth when in neutral.
