DETROIT (March 13, 2015) — General Motors Co. is recalling about 64,000 Chevrolet Volts from the 2011-13 model years for a software update to limit how long the car can be left idling.
The move is to prevent carbon monoxide buildup when a driver forgets to shut off the vehicle.
GM said in a statement to Automotive News that it is aware of two injuries related to the issue, both from carbon monoxide exposure. The problem can occur if a driver inadvertently leaves the plug-in hybrid running while it's in electric mode, which eventually will drain the battery and cause the gasoline engine to turn on.
“If the gas engine runs for a long period of time within an enclosed space, such as a garage, carbon monoxide could build up,” GM said.
The Volt emits a warning chime to alert a driver who has exited the car that the vehicle hasn't been turned off. The software fix will limit the time that an idle Volt can be left in the “on” position.
Trax, Encore recalls
Separately, GM told dealers March 12 to halt deliveries of the 2015 Chevrolet Trax and Buick Encore small crossovers for a pending safety recall to fix a potential loss of electric power steering. A GM spokesman said about 2,300 of the crossovers are subject to the stop-delivery order.
