The top U.S. auto-safety regulator is opening an investigation into reported catastrophic engine failures with some Ford Bronco vehicles, yet another setback in the auto maker’s efforts to improve its quality record.
The National Highway Traffic Safety Administration said in a filing made public this week that it was opening a formal investigation into a series of reports involving 2021 Ford Bronco SUVs that experienced loss of power at highway speeds. The probe covers nearly 25,500 vehicles, NHTSA said.
