10:32 AM EST, 11/04/2024 (MT Newswires) -- The US National Highway Traffic Safety Administration said it has closed an investigation into more than 411,000 Ford (F) SUVs and pickup trucks due to issues related to "allegations of loss of motive power."

"Under normal driving conditions without warning the vehicle may experience a loss of motive power without restart due to catastrophic engine failure related to an alleged faulty valve within 2.7 L and 3.0 L EcoBoost Engines," the NHTSA said.

The regulator said it initially launched a probe in July 2022 into 2021 Ford Bronco vehicles. The investigation later also included other Ford vehicles like the F-150, the Edge, and the Explorer, as well as the Lincoln Aviator and Nautilus, according to documents on the regulator's website.

The regulator said that on Aug. 23, Ford submitted a recall for vehicles with the affected engines.

"In view of the recall action being taken by Ford, [the NHTSA's Office of Defects Investigation] is closing this Engineering Analysis," the regulator said.

Ford didn't immediately respond to a request for comment by MT Newswires.
