2021 Ford Bronco: won't start

Filed Oct 6, 2026 · Fuel system · PA

My car would not start. Turns out it was the fuel pump/filter low pressure recall issue. It was towed to the dealership and has been there since without a remedy from Ford, despite the recall being released over a year ago. Absolutely ridiculous that my vehicle is being held hostage because the manufacturer has not come up with a remedy.

Fuel pump.has low pressure therefore making vehicle stop running completely. Has happened twice , once while driving on highway. This is extremly dangerous to have your vehicle just come to complete dead stop in middle.of road. FORD has no remedy to fix and now i am without a car I am paying for since it wont start now.

I was out offroading in remote desert of Oregon for hours. I stopped with the engine on to hook up my air compressor to refill the air in them before returning to pavement. Truck idled until timeout time and started back up without problem. Drove less than a mile and bronco started sputtering while attempted in move forward. Completed my turn onto the highway and realized there was a problem. Had barely enough time to get to the shoulder where the vehicle wouldn't start again. Pulled negative battery cable to reset, no help. It was very clear there was fuel delivery issue. Tank was full when I started my adventure and was still over half full when the fuel pump/module died. Luckily I just got back into cellular range and was able to call for a tow. I was on a blind corner as well. There really wasn't much time to get the vehcile to safety thus this complaint. Ford replaced the fuel pump and module, with the same part numers. There has since been a part modification. There are others who have had thier fuel pumps fail.

July 15, 2022 - lost power on I80 during heavy traffic. I had to pull to the side as I could not accelerate. Luckily it restarted and I was able to get home. I took it in for service at the dealership the next day (engine light did not come on until the next morning). I was told it was an issue with the catalytic converter and parts were on backorder but it was safe to drive until the part came in. 3 days ago, on Saturday July 30th, I was in my driveway getting to leave and my Bronco wouldn't start, it turned over briefly and then died. The engine made a loud 'knocking' noise and then complete silence. This was a Saturday so they couldn't schedule a tow until until Monday, its been at the dealership for 2 days and they are waiting to hear back from an engineer. I know it's covered under warranty but I think a recall should be issued before someone dies. I was driving about 60-65 mph when I lost acceleration. There was construction ahead but thankfully, it happened before an off ramp. If it hadn't happened in that spot, I wouldn't have had a shoulder to pull over to.

Whilst traveling at highway speeds on the Jersey Turnpike, black smoke suddenly started emanating from the rear of the vehicle. All power was suddenly lost from the vehicle, with the accelerator pedal being nonfunctional. I was able, even though the vehicle was starting to fill with smoke and leave a trail of smoke behind, navigate across the lanes to the hard shoulder. The engine had of course ceased to run. At this time I exited the vehicle to assess the situation. Upon finding no obvious defects and the smoke having cleared, I reentered the vehicle, to see what the engine would do when the key was turned. The engine would not turn over, with only items running off of battery power. Basically the car was dead. At this time I called a AAA for a tow of the car. Unfortunately AAA can't tow on the New Jersey Turnpike, so a local tow company had to be called, to transport the car to a local exit. After the car was deposited in a car park close by, I then reached out to AAA to transport the car to my local Ford dealer. The Bronco was taken to Stamford Ford, in CT, where after inspection, we were told the car had suffered a "catastrophic failure". The vehicle took over one month before it was returned, as the whole engine had to be rebuilt.

On November 14th, 2021, the 2.7 ecoboost engine on my 2021 Bronco, with 2744 miles, shut off without warning. 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. The vehicle was transported to the nearest Ford dealership. After 6 1/2 weeks at the dealership, the Bronco's repairs were finally complete. 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.
