2025 Ford Bronco Sport engine problems

Filed Oct 4, 2026 · Engine, Fuel system · NJ

On about 5 or 6 occasions over the course of one year, my brand new 2025 Ford Bronco Sport with the Big Bend trim with the VIN number in this report has completely lost engine power with severe engine hesitation with a highly rhythmic / even-patterned computer-controlled-like clicking and severe engine shaking (!!!) and a near stall while traveling from anywhere between 5 and 50 mph and the speed grinds down to a crawl, because it most often happens on an incline (maybe once on flat ground, and never downhill), and either way can be extremely dangerous! Fuel tank was full or half full on every occasion. Oil changed every 5k miles. Luckily at the higher speed, I was on a quiet hilly state highway road. I suspect it can happen at any speed though, which makes it even more dangerous! It is as if fuel stopped getting to the engine in these cases, or a computer failure in the fuel system, but I can be completely wrong about the cause. It is impossible to recreate on command obviously, being that it only happened 5 or 6 times over the course of one year, so neither myself or the dealer can recreate it on command. I complained about it to my local dealer that I bought it from, but they said they saw no codes stored, and of course couldn't recreate it. They suggested I got bad gas, but it has happened this many times. Impossible. It began happening at about 5k miles most noticeably. I currently have 12k or so on it. It's not like a throttle body or any injector or fuel system should be so dirty to cause this at the vehicle's age. No way. This is extremely dangerous. The dealer will not investigate further. Note: When this problem doesn't occur, then engine seems to run well, which leads me to think it is a fuel system / pre-engine problem, if I had to guess. I will include the first most noticeable date. I was driving much more in the first few months of the vehicle, but I let the car break in at speeds below 60 for the first 500 miles or so. I use 87 or higher octane.

The contact owns a 2025 Ford Bronco Sport. The contact stated that while driving at low speeds, the vehicle hesitated while depressing the accelerator pedal. There was no warning light illuminated. The vehicle was taken to the dealer, where the failure could not be duplicated. Upon returning to the residence, the contact received notification of the federal safety agency Campaign Number: 26V122000 (Engine and Engine Cooling). The vehicle was taken back to the dealer, where the recall repair was performed; however, the failure returned two days after the repair. The failure continued for several weeks, and the vehicle was taken back to the dealer; however, the dealer failed to duplicate the failure. A technician stated that the failure was likely due to the excessive hot climate in which the vehicle was being driven and that the hesitation was normal vehicle operation. The manufacturer was notified of the failure, and the contact informed the manufacturer that he did not feel safe driving the vehicle. The contact was then informed that the vehicle did not qualify under the Lemon Law, and the contact was provided a case number. The failure mileage was approximately 6,900.

This is a third occurrence related to the federal safety agency complaints 11749893 and 11750183. On July 15, 2026, at approximately 7:30-7:42 AM, while driving to a scheduled Ford service appointment, the vehicle exhibited hesitation and delayed acceleration at multiple intersections, not isolated to one location. Although the vehicle's auto start-stop feature has been manually disabled, the hesitation at each stop felt similar to that feature engaging and re-engaging the engine. The vehicle then stalled completely at an intersection and would not move for approximately 10 minutes. The check engine light illuminated for the first time during this incident. Kent Police Department was contacted, event number 2026-44221. The vehicle was subsequently dropped off at a Ford dealership on July 15, 2026 for diagnosis under warranty.

While driving home and stopped at a red light, the dashboard displayed a "Service Required" warning followed immediately by a "Shift System Fault" message. The vehicle would not accelerate and stalled in the middle of the road with traffic going around me. I was unable to move the vehicle until I was able to restart it, which took at minimum 2 tries and 5 minutes. The warning cleared after restarting but the vehicle had been purchased 11 days prior with only 18,241 miles. The problem has not yet been confirmed by a dealer but I am scheduled to take it in for inspection. No prior warning lamps appeared before this incident. The vehicle is available for inspection upon request.
