Ford Bronco Sport loss of power problems

Filed Nov 4, 2026 · Engine, Fuel system · AZ

I am filing a safety complaint regarding my 2021 Ford Bronco Sport 1.5L and Ford Motor Company's handling of recall-related repairs. Beginning October 22, 2025, I repeatedly attempted to have the applicable recall work completed through two authorized Ford dealerships. The programs involved include: • Recall 24S24 – the federal safety agency 24V267000 • Customer Satisfaction Program 22N18 – the federal safety agency ID 10233848 Despite multiple dealership visits and Multi-Point Inspections, the work was not completed until November 4, 2026. During this period, my vehicle experienced significant loss of engine power, particularly when traveling uphill and at higher elevations. Powertrain warnings also appeared, creating potentially dangerous driving conditions, especially on highways where maintaining speed is critical. The vehicle is now experiencing a failing turbocharger and other major mechanical problems. My concern is that these issues were overlooked or not properly investigated during previous dealership inspections. Had the necessary work and inspections been performed in a timely manner, these problems may have been identified before my 60,000-mile factory warranty expired. I am now facing substantial repair expenses as a result. I contacted Ford Motor Company's corporate Customer Relations department but was told they could not help. My complaint is not simply about warranty coverage or repair costs. I am concerned about the safety implications of the vehicle's loss of power, the delayed recall work, and whether the recall remedies adequately address the underlying problems. I respectfully request that the federal safety agency review the recall history, investigate the reported loss of power and engine failures, and determine whether additional safety action or investigation is warranted.

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.

I have had issues dating back to when I first got the car with rough idling and it turning off while idling. Most recently about 2 weeks ago experienced inability to turn the car on after fueling with gas. Rough idling and turning off while idling were also associated with gas filling. I took this car to Ford dealership multiple times. Check engine light came on associated with EVAP leak code. Ford dealership unable to diagnosis. I took to an independent mechanic who diagnosed in 10 minutes it is an EVAP purge valve malfunction and that likely this had been defective for some time. I reported this to ford and they refuse to compensate for this. I have seen multiple reports online of same issue with other ford bronco sport dealers. This failure seems abnormally premature and defective design. Concerning it results in loss of power of the vehicle as well.

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.

Air Conditioning / Engine Cooling System / Belts and Pulleys My vehicle experienced a sudden failure of power while driving. When restarting the car as instructed by the vehicle to try and get it back home, it kept losing power. Eventually? there was a loud under-hood popping noise and visible smoke billowing from under the hood. Upon inspection by the dealership the A/C compressor locked up and broke a belt. The purge valve has failed and is leaking. This means the compressor, condenser, purge valve, and ac lines and txv valve needs to be replaced. A broken belt causes an immediate loss of power steering assist, loss of alternator charging, and rapid engine overheating. Experiencing a sudden loss of steering control at highway speeds drastically increases the risk of a severe motor vehicle crash. The vehicle has been taken to an authorized repair facility. Ford has not issued a safety recall for this defect. I would appreciate it if this issue was looked into.

The vehicle's entire powertrain and transmission system failed completely. The vehicle will not turn on, will not start, and the electronic rotary gear shifter is physically locked out, refusing to shift into Park or Neutral. The transmission assembly component is currently available for physical inspection upon request. The sudden loss of powertrain and electrical control module communication caused an immediate loss of motive power, stalling the vehicle and leaving it completely stranded and un-drivable. The physical lockout of the shifter mechanism prevents rolling or shifting the asset safely, creating an immediate rollaway or crash hazard if stranded on an active roadway. The car was also jerking vilolently in the middle of an intersection almost causing an accident where we would’ve been rear ended. Yes. The failure was formally diagnosed and confirmed by an authorized dealership, Jim Taylor Ford in [XXX], under Repair Order (RO) #XXX. The component has been physically inspected and diagnosed by the certified technicians at Jim Taylor Ford dealership, who confirmed a total internal failure. They have ordered an entire replacement transmission assembly under Ford Part Number LX6Z-7000-F and Fluid XT-12-QULV. Symptoms and warning signs began showing around XXX, starting with minor shift jerking then eventually turning into violent jerking within a few days. The vehicle suffered from electrical system degradation and complete module power loss, which directly aligns with the known failure symptoms of Ford's active Powertrain Control Module (PCM) and battery safety recalls (such as Campaign 24S24). Ford Corporate was contacted but is refusing to cover this catastrophic mechanical destruction under the safety recall mandate due to the vehicle's mileage (118,365 miles), despite the physical damage being explicitly caused by the unaddressed manufacturer safety defect.

The contact owns a 2025 Ford Bronco Sport. The contact stated that while driving downhill on the freeway with the adaptive cruise control engaged, the transmission independently shifted into neutral, the vehicle lost power, and failed to accelerate as needed. The vehicle was pulled over to the side of the road and shifted back into drive. The contact exited the freeway, and the vehicle was towed to a dealer. The contact stated that the word “CANCEL” in orange was displayed on the instrument panel, and the vehicle went into LIMP Mode. The dealer was unable to duplicate the failure. The vehicle was not repaired. The engine had seized but was operating under reduced power.
