The problem was discovered to during a production trial, in which one in 50 vehicles exhibited the defect.
At the moment, no crashes or incidents have been reported as a result of the programming error, though it's worth noting that only a third of the 10,179 vehicles covered by the recall actually belong to customers. The rest are either unsold or are awaiting delivery.
GM dealers will reprogram the HVAC software to fix the bug free of charge.
