Do car makers reserve the right to deny warranty? Two cars went on fire and the car maker denied warranty because they think that the drivers were speeding.

Gotta be more to the story, no crash, going so fast they blew up the egine?

They recalled cars BUT there are no parts available to fix them, forcing owners to wait months for the parts to arrive.
