The U.S. government's auto safety regulator has concluded a 2 1/2-year investigation into Ford engine failures after the company took remedial actions to address the issue. The National Highway Traffic Safety Administration revealed that the problem stemmed from intake valves that could fracture within certain 2.7-liter and 3-liter turbocharged engines.
The investigation, which began in May of 2022, encompassed over 411,000 vehicles from the 2021 and 2022 model years, including popular models such as the Ford F-150 Bronco, Edge, and Explorer, as well as the Lincoln Aviator and Nautilus.
