The Columbus lawyer who won a $105 million jury verdict against General Motors in 1993 over exploding gas tanks in a pickup has sued the automotive company again because it has failed to take hundreds of thousands of the same trucks off the roads.

Two suits in federal court in Atlanta contend that GM—after more than two decades of litigation over the fuel tanks—has detailed knowledge of hundreds of injuries and deaths stemming from fires that erupted because of the location of the pickups’ fuel tanks.
