I would guess that one reason we haven't had any apparent issues at 55k is that our car is rarely driven in bad weather. But I should check them out, with only a year left on the replacement warranty.

That goes for the OP too.
The original service campaign 09203D explained the cause of failure:

This could cause premature wear of the ball joint, which could result in a clunking or rattling noise when the vehicle is driven over rough roads, wheels out of alignment, and/or premature tire wear.

FWIW when I bought mine the LBJ was so bad it had killed the inner bushings on the arms. The arms are so cheap its easier to just buy a complete set with all new stuff anyway though.

Another one is the rear ABS harness/sensors. I believe this one to be a mostly northern car thing though.

The radio screen/AC control will just not turn on sometimes. Apparently its some bad connections between the screen and board. Fairly common from my research
