I don't remember the specifics about that situation. Something melted and slowly leaked and eventually caught fire. I don't think whatever happened in that case rose to become a recall. It was a relatively new Cadillac in the mid 1990s IIRC. I was a kid at the time it happened.

But yeah, vehicle fires happen to parked cars all the time. As mentioned I've had multiple cars have "don't park in the garage" kind of recalls, one car has even had multiple (Hyundai). In the article posted above it opens with:

> WHILE SOME FIRES in motor vehicles occur as a result of collisions, most occur in motor vehicles not involved in collisions. These non-crash-induced fires are relatively frequent (one for every 1,000 registered vehicles) but in general are less hazardous to occupants and bystanders than crash induced fires.

It later states:

> They occur on an average of one out of every 1,000 registered vehicles and can result in significant property damage
