GM Temporarily Stops Selling Vehicles To Fix OnStar Software Glitch

Posted Sep 8, 2012

General Motors has stopped selling most of the popular 2013 vehicles because of a software glitch that affects OnStar communication systems.  GM spokesman Alan Adler said on Friday that the company is working on fixing the problem on 60,000 vehicles on dealer lots.  The affected models are the 2013 Chevrolet Cruze, 2013 Equinox, 2013 Volt, 2013 Cadillac XTS, 2013 Cadillac ATS, 2013 Buick Verano, 2013 GMC Terrain, and the 2012 Cadillac SRX.  “This should be wrapped up in days, maybe into next week,” said Adler.

The software glitch is a problem that prevents OnStar’s crash notifications system from sending an alert to the OnStar call center in accidents that does not trigger an airbag deployment like a rear-end collision.  The software glitch does not affect the crash notification system in severe accidents,  nor does it prevent airbags from deploying.

The OnStar emergency button is not affected and will still connect the driver to an emergency rep.  GM notified dealers in a memo on Wednesday to “stop the delivery” of the vehicles until they were fixed.  The memo said that the fix “will be completed by late September.”

GM found out about the problem when doing crash testing.  GM does not know about any customers that has been affected.  Vehicle owners were notified about the problem in August.  Some models have been fixed remotely.
