The National Highway Traffic Safety Administration is taking a second look at Audi A6-family models. Last March, the agency recalled some 173,000 A6, S6, and Allroad models after reports of dashboard fires, but it has since heard of more incidents, and is thus revisiting the issue.

NHTSA is also checking in to some 700,000 Ford Super Duties (MY 1999-2001) after 31 complaints of stalling engines that resulted in three low-speed accidents.

In addition to the potentially leak-prone gas tanks NHTSA announced it was investigating on Tuesday, NHTSA is reviewing an existing recall of approximately 38,000 2004 Chrysler Pacificas, also due to stalling engines. The agency has received 60 complaints covering 2004-2006 examples, so it is re-opening the books on the problem.

Finally, NHTSA is turning its gaze to 2004-2005 Toyota Siennas equipped with run-flat tires after 12 owners complained that the tire pressure warning system failed to do its thing.
