Because of a problem with OnStar's software, General Motors has ordered a stop-sale on some of its most popular Chevrolet, Cadillac, Buick, and GMC models. The glitch will keep the car's OnStar system from notifying the call center that the vehicle has been in a crash that's has not caused an airbag deployment.
There are eight affected models: the 2013 Chevrolet Cruze, Equinox, and Volt; the 2013 Cadillac ATS and XTS; the 2013 GMC Terrain; and the 2012 Cadillac SRX. Some 60,000 vehicles need to have their software updated, which can be done remotely in some cases. However, not all cars have been able to be updated through the OnStar system and will have to be reprogrammed manually by dealers.
GM spokesperson Alan Adler told Automotive News that the issue should be resolved by the end of this week. Most of the cars that are affected by the software issue are still on dealership lots, and GM has instructed dealers not to sell them until they've been fixed. Adler also made it clear to both us and AN that the software glitch will not cause any problems with the airbags deploying, just the crash notification to OnStar.
Owners with cars that need to be fixed began being contacted at the end of last month, and GM expects the glitch to be fixed in all vehicles by the end of this month.
