The number of approved death compensation claims related to a recall of a faulty General Motors ignition switch has risen to 84. The claims were approved by a fund set up by GM to compensate victims of a defective part in mid-to-late-2000s model cars that has led to a massive recall and a federal investigation. The number of approved claims stood at 19 in mid-September and had grown steadily to 36 at the beginning of December and then to 42 in January.
