General Motors Co.
said Monday it is upgrading the software on about 4,000 2013 plug-in hybrid Chevrolet Volt cars because a glitch could cause the electric motor to shut down.
GM said the issue only affects owners that use the delayed charging function that allows users to recharge the vehicles at certain times.
A Volt owner on a fan site www.GM-Volt.com reported receiving a call from a GM adviser "that there has been a problem with some of the 2013 Volts mysteriously turning off the electric motor while driving. Apparently the steering and brakes will still work, but you have to safely coast to a stop, turn the car off and then power it up again 2-5 minutes later."Read Article
