The National Highway Traffic Safety Administration (NHTSA) has opened an investigation involving the Ford Bronco. More specifically, Broncos that are equipped with the 2.7-liter EcoBoost V6 engine. According to the Office of Defect Investigation (ODI), three petitions were submitted in March requesting a defect investigation of alleged valve defects on select Broncos.

The NHTSA document states that 2021 model year Ford Bronco units are involved, and ODI recorded 32 complaints in connection with this alleged failure. The document’s problem description says that “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 EcoBoost engines.”

The 2.7-liter Ecoboost V6 turbocharged engine is the more powerful option customers could choose from for the Ford Bronco, offering 330 horsepower and 415 lb-ft of torque. It’s also found in the Ford F-150. The base engine is a 2.3L EcoBoost four cylinder, which is also found in the Ford Ranger and Ford Mustang.

As of May 31, 2022, 50 reported units on the Bronco6G forum have experienced engine failure. Some vehicles only have 3 miles while others have almost 7,000. Though it’s unconfirmed at this point, reports have stated that the issue lies with valves used in the 2.7-liter engine, which were supplied by a vendor. It seems that a bad batch of valves has defects that cause them to become brittle from the heat of the combustion.

The issue is still under investigation, and it appears that not all of the 25,000 2021 Ford Bronco units are affected. At this time, it’s unclear if other Ford products equipped with the same EcoBoost engine are experiencing the same issue. The ODI didn’t disclose when the investigation involving the Bronco units began. The petitions are under ODI numbers 11461178. 11460125, and 11460124.

Zac's love for cars started at a young age, after seeing the popular Eleanor from Gone In 60 Seconds. From there, fascination and enthusiasm blossomed and to this day the Ford Mustang remains a favorite. His first job started out detailing cars, but also provided the opportunity to work on restoration including an 1968 Ford Mustang, Ford Firebird, and a C3 Corvette, though he left that job before further work and experience could be had. From there, he was a detailer at a car dealership before quitting that job to try and finish college.

Much of his free time while studying was spent watching YouTube videos regarding new cars, or off-roading. 4WD247 is a personal favorite channel which rekindled a dying flame in car enthusiasm, now tailored towards trucks and SUVs and the fun that can be had building up an overlanding rig, and going on adventures, though, that chapter remains unwritten for the time being.
