DETROIT -- General Motors last week 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, Sept. 7, that GM was working to fix the problem on 60,000 vehicles. Affected vehicles are the 2013 Chevrolet Cruze, Equinox and Volt; Cadillac XTS and ATS; Buick Verano; and GMC Terrain. The 2012 Cadillac SRX is also affected.
"This should be wrapped up in days, maybe into next week," Adler said on Friday.
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.
The software glitch does not affect the crash notification system in accidents that set off the airbags, Adler said, nor does it prevent the airbags from deploying. Operation of the OnStar emergency button is unaffected and should connect the driver to an emergency adviser as it does normally.
Some vehicles already are cleared for sale, after GM fixed them through a software upgrade installed remotely through the OnStar system. But because that method hasn't worked on all of the affected vehicles, GM is having dealers fix the remainder through a manual upgrade on their lots.
On Wednesday, Sept. 5, GM notified dealers in a memo to "stop the delivery" of the vehicles until they were fixed. That memo said the fix "will be completed by late September."
Owners of the affected vehicles were notified of the problem in late August. Some of those vehicles have been fixed remotely, too, Adler said, though he could not say how many.
