Jeanne Moore (plaintiff) purchased a 2002 Ford Explorer manufactured by Ford Motor Co. (Ford) (defendant). Moore was six-feet tall and weighed approximately 300 pounds. Moore was driving when she was rear-ended at low-speed, and her seat collapsed backward. This caused Moore’s head and shoulders to hit the back seat. As a result, Moore fractured a vertebra and became paralyzed. Moore sued Ford, alleging that Ford failed to provide a warning that the driver’s seat would collapse in a rear impact with a driver of Moore’s size and weight. Moore presented evidence that the design of the driver’s seat resulted in a collapse if the vehicle was rear-ended at mild to moderate speeds and the driver was of a similar height and weight to Moore. Moore testified that she would not have purchased the vehicle if she had been warned of this design. The trial court granted a directed verdict for Ford, and Moore eventually lost the case. Moore appealed. After an appellate opinion, the Missouri Supreme Court heard the case.
