The National Highway Traffic Safety Administration (NHTSA) said in December it had opened a formal safety probe into the GM robotaxi unit Cruise after reports of three crashes in which Cruise vehicles were struck from behind by other vehicles after the autonomous vehicles braked quickly, resulting in two injuries.
"Inappropriately hard braking results in the Cruise vehicles becoming unexpected roadway obstacles and may result in a collision with a Cruise vehicle," NHTSA said in its letter.
The DMV in August had directed Cruise to remove half of its driverless vehicles after another crash.
