The automaker issued a recall for 19,205 examples of the Q7 after it was discovered that the Q7's third row seat backs may move forward during a frontal collision. A seat back moving under load violates Federal Motor Vehicle Safety Standard 207, "Seating Systems."

In a case like this, a recall isn't just voluntary -- it's mandatory. Seats shouldn't move during collisions, as they're meant to secure passengers and prevent them from ending up on the receiving end of some nasty physical forces.

The fix is relatively simple. Audi will take the recalled Q7s and add an additional support bracket to the seat back. The recall should start in October, and in conjunction with the law, the automaker will send out notifications to all affected owners by first-class mail.
