The state Superior Court has affirmed a $15.6 million verdict awarded to a driver and passengers in a Toyota van who were injured when the vehicle malfunctioned and careened into a ravine.

A three-judge panel in Lewis v. Toyota Motor upheld a Philadelphia jury’s award of roughly $11.3 million to Dr. Noreen Lewis, the driver of the rented Toyota Sienna minivan, and roughly $4.3 million to the five passengers who rode with her. The verdict was rendered against the Center City Toyota and Ardmore, Pa., Toyota dealerships, which the plaintiffs claimed did not properly inspect the van for problems.
