At a congressional hearing yesterday, General Motors CEO Mary Barra hinted that the ignition switch issue may go beyond GM's doors. It seems that may be true. The National Highway Traffic Safety Administration announced it has opened two probes into similar possible ignition switch defects in about 1.25 million Chrysler vehicles. The investigation, which Chrysler officials said they are cooperating with, actually has a tie to GM’s recent issues, according to the safety agency.
