General Motors’ startup unit Cruise LLC (GM.N) said Thursday it had recalled and updated software in 80 self-driving vehicles after a June crash in San Francisco that left two people injured.

Federal regulators said the recalled software could “incorrectly predict” an oncoming vehicle’s path. Cruise said it had determined this unusual scenario would not recur after the software update.

The National Highway Traffic Safety Administration (NHTSA) has stepped up its scrutiny of advanced driver assistance systems and autonomous vehicle systems in recent months. Last year, it directed all automakers and tech companies to promptly report crashes involving self-driving vehicles.
