NHTSA Investigating Ford Bronco over Complaints of 'Catastrophic Engine Failure'

• NHTSA's Office of Defects Investigation is looking into complaints that owners' 2021 Ford Bronco SUVs suddenly stopped running and would not restart.

• The cause is believed to be a possible valve defect in the 2.7-liter EcoBoost engine, which is standard on the 2021 Bronco Wildtrak and optional on most other models.

• The safety agency received three separate petitions in March 2022 requesting the investigation, which could lead to a recall if the results warrant one.

The ultra-popular Ford Bronco is now being investigated for a possible recall after 32 owners complained that their 2021 model SUVs stopped running suddenly and would not restart. The National Highway Traffic Safety Administration's Office of Defects Investigation is currently at the stage of reviewing three separate petitions filed in March asking for an investigation into the issue.

According to the agency's documents, the problem is believed to relate to a defective valve in the 2021 Bronco with the 2.7-liter EcoBoost engine. That engine is standard on the Wildtrak (pictured above) and optional on all other models except the Everglades and Raptor, on which it's not available. NHTSA describes the problem this way: "Under normal driving conditions without warning, the vehicle may experience a loss of motive power without restart, due to a catastrophic engine failure related to a faulty valve within 2.7-liter EcoBoost engines."
