Is there a problem with the engine?

Yes, there is definitely a problem with the 2021 Ford Bronco engine. Engines are reportedly failing countrywide.

In addition to at least 28 complaints to the National Highway Traffic Safety Administration (NHTSA) that describe catastrophic engine faults, there is an open investigation that relates to loss of motive power due to an engine defect.

Many consumers are calling for a recall of the defective valves that the Office of Defects (ODI) is investigating.

ODI Investigation

Opened on May 27, 2022, the ODI investigation follows three petitions in March 2022 that request an investigation into an alleged defect of the valves on 2021 MY Ford Bronco vehicles. All of these Ford Broncos are equipped with a 2.7L Eco-boost engine.

The petitioners identify the complaints lodged with the NHTSA. They allege that 2021 Ford Bronco vehicles experience a loss of motive power at highway speeds. They state that to make it worse, there is no restart because the engine failures are catastrophic. The only option is to replace the engine.

What Engine Problems are Owners Experiencing?

So far, NHTSA complaints range from late January 2022 to May 2022. They state that dealers blame defective valves for engine failure. Almost as many complaints state that dealers told them the Ford Bronco engines simply need to be replaced.

Some complaints describe incidents they maintain put them in seriously dangerous predicaments. There are also numerous complaints that 2021 Ford Bronco owners have aired on several forums. Some wisely recommend that owners complain to the NHTSA.

Here are some examples of what NHTSA complaints say.

An owner from Virginia states:

“I was traveling on the interstate, going approximately 75 mph, with my girlfriend and elderly mother as passengers. The Bronco lost all acceleration and the ‘service engine’ light came on. Fortunately, I was able to coast to the nearest exit ramp. After bringing the vehicle to a stop, I attempted to restart the Bronco to no avail. The starter would engage, but the engine would not fire back up. I unhooked the battery cable in an attempt to reset the electronics, but this did not work either. I then checked to make sure all of the fuses were tight, but the vehicle still wouldn’t start.”

This happened without warning when the Bronco had only 2,744 miles on the clock. The owner had the vehicle transported to the nearest Ford dealership. It took 6½ weeks to repair the Bronco.

“The dealership had to replace the entire engine. Based on the paperwork given to me by the dealership, cylinders 4, 5, and 6 had low compression, cylinder 6 spark plug was found mashed from the piston, and they found catastrophic failure in cylinders 4, 5, and 6. Also, the paperwork states that metal was found in the oil, cylinder 6 intake valve was found in the intake manifold, and metal chunks were found in the intake manifold and turbos.

“Needless to say, we were all pretty shaken up over losing complete acceleration and power on the interstate. We were very fortunate there was an exit ramp close to us, but this could have turned out very differently. I feel like we were unnecessarily put in a dangerous situation in an essentially brand new vehicle.”

A more recent complaint from Alaska in March 2022 states:

“I was driving near my home when my vehicle stopped running. I did feel a strange pull in my steering and tires, but I was also driving on ice and assumed it was the traction control system at play. I was wrong. It was my engine losing compression and my engine failing. My dash lit up with a series of errors (all in quick succession and could not catch them all) and my vehicle lost all power and control.

“As mentioned above, I was driving on ice-covered roads and had difficulty steering. I attempted to pull off the road and into a parking lot; however, the drive sloped up and I could not get clear of the entryway. I had to stop blocking the entrance to the veterinarian’s parking lot. To increase the risk here, my vehicle was not visible from traffic turning in because of snow banks that were taller than my vehicle.

“I want to stress how incredibly lucky I was that this happened close to home. I went on a road trip and had returned home the night before. We had contemplated taking the Bronco. If we had, we would have broken down on the Parks Highway in Alaska. This highway is remote at most times with spotty cell service. The risk of having broken down in subzero temperatures with zero help was extremely high in my area. I also consider myself extremely lucky that I had a friend that was able to come move my vehicle from blocking the business entrance.

“When I used the Ford app to get a tow, it quoted me 7 hours. I did call and complain that that was unacceptable. The vehicle was towed to the dealership and catastrophic engine failure was determined with a faulty valve being the contributing factor. This is a known valve issue and I have included my engine build date sticker in the photos. I included a photo of my Bronco being loaded on the tow truck showing the ice roads and snow bank blocking my car from view.”

Other owners have similar complaints:

An even more recent complaint filed in May 2022 describes how engine failure in Granite Bay, California enveloped a 2021 Ford Bronco in smoke.

“My wife was driving the vehicle and was enveloped in smoke and the engine stopped and she was stuck in the middle lane of a busy road in rush hour. A dangerous section of road a few miles from our house. I drove down and gave her my SUV and then called AAA who towed it to the dealership.

“The motor was dead. The vehicle was towed to Future Ford of Sacramento. They then diagnosed it a few days later and informed us that it is a complete engine failure and that it will take several months to get the vehicle back to us. There were no warning lights or any warning prior to the engine stopping and a large amount of smoke to the point that my wife thought the whole vehicle was on fire. Four people stopped to help her and get her to the side of the road.”

Another complaint from Michigan states:

“I was driving to work on the morning of March 14, 2022, on the highway (traveling at) approx. 70 mph. I felt a falter or engine buck, I began to lose power to the engine. The engine light began to flash and I was only able to drive 55 mph. I was in a very unsafe area on a highway with a very narrow shoulder and so I proceeded to manage my speed to reach work safely. I was able to make the additional 10 miles to my workplace. When I stopped at the gate for security, the engine died and I was unable to restart it.”

Yet another complaint, this time from Ohio, states that with only 625 miles on the clock of a new 2021 Ford Bronco, the low engine oil pressure alert came one. After having the vehicle towed to a dealership, this new owner discovered that the engine would need to be replaced.

“It has now been two months and I’m still waiting for my vehicle to be repaired.”
