Cruise, the self-driving vehicle unit of General Motors, has issued a voluntary software recall after Californian regulators suspended the company’s license to operate in the state following an accident that left a woman severely injured.

The recall of 950 vehicles will address a software problem in the car’s response to collisions, Cruise said in a report submitted to federal regulators. Depending on the circumstances of an accident, driverless Cruise cars will either pull over out of traffic following a collision or in some cases remain stationary, it said.
