2021 Ford Bronco 'catastrophic engine failure' complaints lead to NHTSA investigation

The 2021 Ford Bronco is now the focus of a federal safety investigation after 32 Bronco owners complained of alarming engine failure experiences.

"Under normal driving conditions without warning the vehicle may experience a loss of motive power without restart due to catastrophic engine failure related to a faulty valve within 2.7 L Eco-Boost Engines," according to the National Highway Traffic Safety Administration (NHTSA) report. It says the investigation opened May 27.

Documents filed by Ford with NHTSA say 25,538 Broncos may have this problem.
