2021 Ford Bronco Investigated Over Reports of Engine Failure [UPDATED]

2021 ford bronco investigated over reports of engine failure updated

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.

  • DenverMike When was it ever a mystery? The Fairmont maybe, but only the 4-door "Futura" trim, that was distinctively upscale. The Citation and Volare didn't have competing trims, nor was there a base stripper Maxima at the time, if ever, crank windows, vinyl seats, 2-doors, etc. So it wasn't a "massacre", not even in spirit, just different market segments. It could be that the Maxima was intended to compete with those, but everything coming from Japan at the time had to take it up a notch, if not two.Thanks to the Japanese "voluntary" trade restriction, everything had extra options, if not hard loaded. The restriction limited how many vehicles were shipped, not what they retailed at. So Japanese automakers naturally raised the "price" (or stakes) without raising MSRP. What the dealers charged (gouged) was a different story.Realistically, the Maxima was going up against entry luxury sedans (except Cimarron lol), especially Euro/German, same as the Cressida. It definitely worked in Japanese automaker's favor, not to mention inspiring Lexus, Acura and Infiniti.
  • Ronnie Schreiber Hydrocarbon based fuels have become unreliable? More expensive at the moment but I haven't seen any lines gathering around gas stations lately, have you? I'm old enough to remember actual gasoline shortages in 1973 and 1979 (of course, since then there have been many recoverable oil deposits discovered around the world plus the introduction of fracking). Consumers Power is still supplying me with natural gas. I recently went camping and had no problem buying propane.Texas had grid problems last winter because they replaced fossil fueled power plants with wind and solar, which didn't work in the cold weather. That's the definition of unreliable.I'm an "all of the above" guy when it comes to energy: fossil fuels, hydro, wind (where it makes sense), nuclear (including funding for fusion research), and possibly solar.Environmental activists, it seems to me, have no interest in energy diversity. Based on what's happened in Sri Lanka and the push against agriculture in Europe and Canada, I think it's safe to say that some folks want most of us to live like medieval peasants to save the planet for their own private jets.
  • Car65688392 thankyou for the information

  • MaintenanceCosts There's no mystery anymore about how the Japanese took over the prestige spot in the US mass market (especially on the west coast) when you realize that this thing was up against the likes of the Fairmont, Citation, and Volaré. A massacre.
