2024 Ford Bronco Sport: sudden loss of power

Filed Nov 3, 2026 · Transmission · NM

While driving home from work the vehicle slid like it was hydroplaning but there was not rain or water on the freeway but was unsure why the vehicle would do this. The next day after work getting in the vehicle I received an alert that the powertrain malfunction/reduced power. After checking the vehicle the knuckle hub assembly was found to be completely cracked trough. This part is completely unavailable through Ford and any other market places. When I went to the nearest dealer ship to check any warranties I was told that the vehicle was not within the timeframe of any of the warranties to be able to cover this. This is my primary vehicle to use and because of this broken part it is unsafe to be driving.

The vehicle shut off and lost power while I was driving this July. It happened while I was in the turning lane, about to turn onto the interstate. There were no warning lights on the dashboard, so I had no indication of an issue or any forewarning that the vehicle would shut off. When it shut off, it then restart but would not allow me to use the gas. The engine and battery light came on. Had I made it onto the highway and had the vehicle shut off, the situation could have been significantly more dangerous. Luckily the cars behind me were paying attention and able to swerve around my sporadic spot without any warning from a brake light. I had the vehicle towed to Ford for repair. They said it was an issue with the fuel tank sensor and they repaired it. The exact same thing happened again, less than two months later in early September, this time while I was in the middle of a busy intersection. Again the car behind me slammed on his brakes and I flipped on my hazards and inched slowly to a safe spot. The same lights came on, but when I turned the car off and back on, all the lights were off. Ford replaced the fuel line, but they haven’t been able to find what caused it to shut off or recreate the issue.

When coming from a stop at a traffic light vehicle losses power for approximately 15-20 seconds. This puts the driver of the vehicle, passengers, and other vehicle drivers operating on the roadway in danger of a major collision, possible bodily harm or even death. We have twice taken the vehicle to our dealership, where we purchased the vehicle; in order to fix the recall and we have had no success in gaining a remedy for the issues. The vehicle was seen twice by the Chandler, Arizona Earnheart Ford service department. There were no warning signs before the incident and they started appearing soon after the purchase of the vehicle. We have notice that the hotter it is outside the more frequent the loss of power occurs.

When the car has been driven for more than 20 minutes it has erratic shifting issues shifting up or down. It is most notable when in stop and go traffic. Four times it has given me a wrench on the dash cluster for Powertrain Malfunction/Reduced Power. At the time it suggests to contact a dealer. I pull over as soon as I can, shut the vehicle off, and restarted and the wrench goes away. It will then drive normal again. It has happened on 8/25/24, 10/5/24, and twice on 3/22/25.
