Senator calls on NHTSA to explain why it won’t investigate GM steering sensor

A Democratic senator is asking the National Highway Traffic Safety Administration why it decided against opening an investigation into an allegedly defective steering sensor on thousands of General Motors Co. vehicles.

Sen. Richard Blumenthal of Connecticut sent a letter to NHSTA urging the agency to further investigate the sensors and control systems. Reuters first reported last week that the administration would not be opening a formal investigation on the sensor systems after reviewing information in a lawsuit that was filed by the widower of a woman who died in a crash allegedly caused by the faulty sensor.
