The National Highway Traffic Safety Administration (NHTSA) said on Oct. 2 it was expanding its investigation into 708,000 Ford Motor Co. sport utility vehicles (SUVs) and trucks built with a faulty valve that could lead to catastrophic engine failures.
The agency says that under normal driving conditions vehicles without warning may experience a loss of power due to catastrophic engine failure related to a potentially faulty valve in 2.7 L and 3.0 L EcoBoost engines.
