In August while driving at highway speed on I-94, the engine started to stall in traffic with no warning lights or indicators. Outside temperature was in the mid 80’s. Had to carefully pull over and restart the vehicle, it continued to intermittently stall. After turning ignition off and restarting it cleared up. This is the third time this has happened in traffic at highway speeds. Once in June, once in July and this time in August. There is a recall for this, but it is concerning to drive on the highway.

My Bronco died and would not restart. Beach Ford diagnosed it as a fuel pump replacement. Luckily, I was in a car wash drive approach lane when this occurred. I was not on any roadway when the Bronco stalled. The Engine light appeared on the instrument panel.
While driving my family of 4 the week before last, our Bronco without warning began shaking and then lost all power / ability to accelerate. I was able to pull to the side of the road before the engine completely shut off. A warning light then showed indicating “manual restart required” for which I could not locate any information in the manual. This happened in 110 degree heat and with young kids in the car. There was no previous warning and the engine would not reengage. Vehicle had to be towed 100 miles to Ford dealership nearer to our home. Dealership diagnosis indicated the problem was the fuel pump which then was replaced, although they did not acknowledge that this was a “known” issue. We were fortunate this happened in an area where we were able to pull over outside of a direct traffic lane and did not happen 15 minutes later where we would have been traveling at high speed on a busy freeway.
Vehicle stopped multiple times over the course of 2 weeks. 1 time it shut off while driving on a side road. I was able to restart and continue on. The last time it shut off in my driveway abs would not start again. Vehicle Ford dealership was recently towed to Ford dealership awaiting repair.
While sitting in the Bronco talking on the phone in a parking lot, it shuddered and then stopped. It could not be restarted. Had to have it towed to the dealership. Current diagnosis is that there is a faulty fuel pump.
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.
On June 9, 2022, while traveling on an Interstate Highway at about 80 mph, the engine sputtered and died without any warning light activation. The vehicle failure caused an extremely unsafe condition which caused me to navigate without power, in moderate traffic, from the #1 lane, across the #2 lane and onto the shoulder. The failure caused me to perform this high risk maneuver in front of an approaching big rig traveling in the #2 lane. The vehicle was towed to the nearest Ford dealership where an inspection determined the fuel pump had failed. The fuel pump was replaced but the dealership did not know if the replacement had been redesigned to prevent such catastrophic failures in the future. The loss of power was sudden and immediate without any prior warning messages and/or warning lamp activation.
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.
