DETROIT -- General Motors has stopped the sale of several of its most popular 2013 vehicles because of a software glitch that affects their OnStar communication systems.
GM spokesman Alan Adler said late Friday that GM is working to fix the problem on 60,000 vehicles on dealer lots. The affected models are the 2013 Chevrolet Cruze, Equinox and Volt; the Cadillac XTS and ATS; the Buick Verano and the GMC Terrain. The 2012 Cadillac SRX is also affected.
"This should be wrapped up in days, maybe into next week," Adler said.
A software problem prevents OnStar's crash notification system from sending an alert to the OnStar call center in accidents that do not trigger an airbag deployment, such as a rear-end collision, Adler said.
The software glitch does not affect the crash notification system in more-severe accidents that set off the airbags, he said, nor does it prevent the airbags from deploying.
