OnStar bug forces GM to halt deliveries on 60,000 vehicles

General Motors stopped the sale of certain 2013 Chevrolet Cruze, Equinox and Volt models as well as 2013 Buick Verano units, GMC Terrain crossovers and 2012 Cadillac SRX, XTS and ATS vehicles due to a problem with the onboard OnStar crash notification system. According to Automtotive News, the affected units would not notify emergency responders of an accident in any collision that did not actuate the vehicle's airbags. That could include rear-end impacts. GM says the software glitch won't take long to address and doesn't impact the crash notification system in accidents that involve deployed airbags. The trouble doesn't prevent the airbags from deploying, either.

All told, the stop-sale covers around 60,000 vehicles already on dealer lots. GM has already cleared some of those for sale thanks to a remote reflash sent through the OnStar system. Automotive News reports that unfortunately, the fix hasn't worked on every vehicle, and dealers are having to manually install the fix on the remainder of the impacted units. GM expects the repair to be completed by the end of September.
