they had fires just from a parked car that is off? that doesn't seem right.

Yup! One example: brake fluid leaking onto the electrical system and igniting.

I stand corrected... dang!

Yes, in fact there were two different recalls, announced within days of each other, that both led to that result:

1. An electrical short can cause the parts within the PCV valve to melt, increasing the risk of a fire, even when the vehicle is not in use.

2. Wiring that overheats could cause the electrical connectors to melt, and increase the risk of a fire, even when the vehicle is unattended.
