2021 Ford Bronco electrical problems

Filed Aug 13, 2026 · Brakes, Electrical · GA

While driving, I experienced the brakes beginning to fail, followed shortly by a complete loss of engine power. My 2021 Ford Bronco is subject to recall 25S75 (the federal safety agency 25V455) for a low pressure fuel pump defect that can cause loss of fuel pressure or flow and engine stall. I was stranded on the side of the interstate in 100 degree heat with my newborn in the vehicle. This was a dangerous situation, not a minor inconvenience. I had the vehicle towed to an AAA Car Care Center in Charlotte, NC, where the fuel pump failure was diagnosed. AAA could not perform a repair because the issue falls under an open safety recall. I contacted the Ford Recall Assistance Center and was told no remedy is currently available for recall 25S75. I also visited Capital Ford Charlotte, who confirmed the same, that no remedy exists yet. With the vehicle inoperable and no repair available anywhere, I paid out of pocket for private transport to move the vehicle to my home in Newnan, GA, since Ford could not confirm coverage for towing to my home dealership. As of August 12, 2026, the federal safety agency materials still list the remedy for 25S75 as under development. My vehicle remains inoperable with no path to repair. This is now also preventing me from selling or trading the vehicle. A dealership (Buford Toyota) declined to even appraise it because it will not run. I am filing this complaint to document that an open, unremedied safety recall directly caused a vehicle failure that endangered myself and my infant child, and continues to leave the vehicle unusable and unsellable months later.

Window actuator does not properly open or close passenger window to open door properly, which is a safety risks to a child. Window could shatter because window will not roll down the inch or so to pull the door open. In order to open the door, the window will shake vibrantly and risk of a child of a possible window shatter. Ford says this is a normal wear and tear and it’s at owners cost to replace. To me that’s unacceptable.

I am submitting a safety complaint regarding my Ford vehicle’s infotainment screen failure, which has been identified under a recall but currently has no available remedy or repair timeline. When the screen goes blank or becomes unresponsive, I lose access to critical safety features, including the rearview camera, which is federally required. This significantly increases the risk of accidents while reversing, especially in areas with pedestrians. The system also affects access to navigation, hands-free communication, and important vehicle alerts, forcing me to either drive without these features or become distracted trying to compensate. Although Ford has acknowledged this issue, there is no clear timeline for a fix, and no accommodations have been provided. I am expected to continue driving a vehicle that does not meet expected safety standards, which puts both myself and others at risk. I rely on my vehicle daily, including transporting passengers, and the lack of a functioning safety system is a serious concern. The absence of communication and support from Ford regarding a resolution is also concerning. I respectfully request that the federal safety agency investigate this issue and require Ford to provide a timely remedy or appropriate accommodations, such as a loaner vehicle or interim solution, to ensure driver and public safety while awaiting a permanent fix.

The digital gauge cluster where it shows sensitive information is a blacked out screen. I took it an automotive shop to investigate the issue. They ran a diagnositic and confirmed the screen is receiving power, fuses are good, but the screen is not powering up. I cannot view the digital speed, fuel gauge, mileage, access GOAT modes, view tire pressure, view oil life, and other critical data, etc. This first occured a few months ago and would randomly turn back on, but not the screen is black more than it is on. Luckily I am able to track the fuel gauge (miles to empty) on the infotainment screen.

I received an alert on the dash stating there was an issue with the blind spot monitoring/rear cross traffic system. It was erroring off and on for that entire drive. When I got home, I googled the issue and it appears it's a known issue with '21 and some early '22 broncos where they factory installed the blind spot module wiring harness too close to the rear bumper. Over time, the wires rub and eventually rub bare and corrode or short out. I went out to take a look and sure enough, I had rubbed through on the driver side (photo) and the passenger side was nearly rubbed through. I have an extended warranty and it's at the dealership today. This is a manufacturing defect and should be covered (even if out of warranty) in my opinion. We will see what kind of story the dealer can come up with to wiggle out of it being covered under warranty.

Bronco wire corrosion cross traffic refers to a known issue where wiring under the rear bumper, often for the blind spot/cross-traffic sensors, chafes, frays, and corrodes, causing system faults and failures, sometimes due to design flaws or environmental exposure to salt, requiring inspection and repair of the harness. This problem triggers error messages like "Cross Traffic System/Blind Spot System Fault" in the instrument cluster, impacting safety features, with potential fixes involving harness repair, protective sheathing, or sensor replacement. My car’s wiring was corroded due to this flaw and required a repair exceeding $1,000.

Location of wiring from the factory for Blind Spot Warning and Cross Traffic Alert systems is not protected. The wiring has frayed and broken due to the wiring being unprotected, loose and rubbing on the rear bumper, causing the systems to not function. This is a blatant design defect from the factory, causing two safety systems to fail. Reporting now as, to the best of my knowledge, the manufacturer has not issued a TSB or recall and dealerships have acknowledged the issue.

I was driving on the highway at a speed of approximately 70 miles per hour when the Bronco driver screen gave multiple warning notices and at the same time, the accelerator would not react. Steering power was fine. I was in the second from far left lane on a six lane highway and losing speed quickly. I was able to move to the right and drift to the side of the road without incident. Once stopped, I turned the ignition off and waited a few seconds and then turned it back on again. The error messages all cleared and the Bronco accelerator reacted appropriately. I drove it straight to the dealership for inspection. They found the 210 connector was not making a good connection. They cleaned it and added electric grease and reconnected. Everything cleared and the connection was deemed good. I have not worked in the Bronco engine compartment or had work done that would have resulted in loosening the 210 connector. My understanding from the shop is that corrosion caused this connector to loosen.

I have been getting a message that my blind spot and cross traffic alert deactivated because trailer is attached. I have never had a trailer attached but do have a trailer hitch- the dealer said Ford refuses to pay to have it fixed because the bumper to bumper warranty is out. the car has been garaged and has only 9,000 miles on it. This is a safety issue that I think they should cover as I have no blind spot or cross traffic warnings.
