Complaints of “catastrophic engine failure” involving the 2021 Ford Bronco have led to the National Highway Transportation Safety Administration (NHTSA) initiating a Federal Safety Investigation.

The 2.7-liter EcoBoost engine in the Ford Bronco has become a source of investigation after 32 consumers complained of their engines completely failing in normal, everyday driving conditions. The investigation was opened by NHTSA on May 27.

According to NHTSA, “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”.

Editor’s note: The original headline incorrectly stated that the Bronco had been recalled. This is not the case. We have fixed the headline to more accurately reflect this and we regret the error.

As many as 25,538 Ford Broncos could be affected by this condition, according to papers Ford filed with the federal agency.

The inquiry, which was initially reported by Carscoops and Ford Authority, seeks to determine if Ford will be required to recall the vehicles for engine repairs. The Federal Office of Defects Investigation has received three petitions requesting these investigations on March 17, 18, and 29. The petitions are currently under review by the agency.

“The petitioners alleged that 2021 MY Ford Broncos vehicles are experiencing loss of motive power at highway speeds with no-restart due to catastrophic engine failures,” the federal safety agency has written on its website.

The affected 2.7-liter EcoBoost engine is available as standard equipment on the Wildcat and as an optional engine on all other models except Everglades and Raptor.

Car and Driver is reporting that Ford has told them they are aware of a select number of engines affected and that Ford is cooperating with NHTSA on the matter as well as any consumers who have the 5-year/60,000-mile powertrain warranty.

The 2021 Bronco currently has two safety recalls outstanding: One from October 2021, involving 553 vehicles for potential passenger airbag deployment issues; the other for a misaligned radar module that could cause affected vehicles to not maintain proper distance while using the adaptive cruise control feature.

    So, we've gone from engines that had lots of little problems with emissions and fuel injection and ECUs to engines that are super reliable until they prematurely catastrophically fail.

    This sounds newsworthy: "Over the past nine months, more Wrangler owners have defected to the Bronco than any other brand, with defection rates reaching between 9-10 percent in the first three months of 2022."

      @Jeff S - A friend of mine had an engine failure with his 2.0 turbo in his brand new Jeep Wrangler Unlimited Rubicon. His Jeep was 6 weeks old. He also had an engine failure with his 3.6 V6 in his old Jeep just off of warranty.

  • Ollicat I have a Spyder. The belt will last for many years or 60,000-80,000 miles. Not really a worry.
  • Redapple2 Cadillac and racing. Boy those 2 go together dont they? What a joke. Up there with opening a coffee shop in NYC. EvilGM be clowning. Again.
  • Jbltg Rear bench seat does not match the front buckets. What's up?
  • Theflyersfan The two Louisville truck plants are still operating, but not sure for how much longer. I have a couple of friends who work at a manufacturing company in town that makes cooling systems for the trucks built here. And they are on pins and needles wondering if or when they get the call to not go back to work because there are no trucks being made. That's what drives me up the wall with these strikes. The auto workers still get a minimum amount of pay even while striking, but the massive support staff that builds components, staffs temp workers, runs the logistics, etc, ends up with nothing except the bare hope that the state's crippled unemployment system can help them keep afloat. In a city where shipping (UPS central hub and they almost went on strike on August 1) and heavy manufacturing (GE Appliance Park and the Ford plants) keeps tens of thousands of people employed, plus the support companies, any prolonged shutdown is a total disaster for the city as well. UAW members - you're not getting a 38% raise right away. That just doesn't happen. Start a little lower and end this. And then you can fight the good fight against the corner office staff who make millions for being in meetings all day.
  • Dusterdude The "fire them all" is looking a little less unreasonable the longer the union sticks to the totally ridiculous demands ( or maybe the members should fire theit leadership ! )
