The U.S. National Highway Traffic Safety Administration said on Friday it was opening a preliminary probe into 877,710 vehicles manufactured by General Motors , after receiving reports alleging engine failure.

The agency said it analyzed 2,759 reports identified by Cruise that involved collisions, including 1,113 that involved a “pedestrian conflict.”

The National Highway Traffic Safety Administration’s Office of Defects Investigation has closed their preliminary investigation into General Motors' (NYSE:GM) Cruise division and will take no further action.

Through a newly proposed order, GM and OnStar will be banned from disclosing data for five years from the date the order is entered. The companies must also obtain affirmative express consent from consumers before collecting connected vehicle data, except in some cases, such as providing location data to emergency first responders.

“GM monitored and sold people’s precise geolocation data and driver behavior information, sometimes as often as every three seconds,” FTC Chair Lina Khan said in a statement. “With this action, the FTC is safeguarding Americans’ privacy and protecting people from unchecked surveillance.”
