"Between 2008 and 2014, Viking received 170 incident reports of ranges that had turned on spontaneously and could not be turned off using the control knobs, resulting in extreme surface temperatures that posed a burn hazard to consumers. The reported incidents included two consumers who were unable to turn off the range using the controls and were burned while attempting to disconnect the power source. Viking also received five reports that the ranges had turned on spontaneously and caused property damage to the area surrounding the range. Several consumers called 911 for assistance when they discovered that the ranges had turned on spontaneously and could not be turned off or disconnected. Viking knew of this information, but failed to notify CPSC immediately of the defect or risk posed by the ranges, as required by federal law."
