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.

U.S. automaker General Motors and its subsidiary OnStar agreed not to disclose sensitive vehicle geolocation and driver behavior data to consumer reporting agencies for five years, the U.S. Federal Trade Commission said on Thursday.

The Federal Trade Commission announced Thursday that GM agreed to refrain for five years from disclosing data on geographic locations and driving habits.

The order comes after GM was caught selling customer data to third-party data brokers and insurance companies — without consent.
