Automatic Emergency Braking Problems of Ford Bronco

Brakes did not engage. Rearended another driver. Have not gotten it to dealer yet. Police report made. Insurance working on claim. Need to get fixed first before getting it to the dealer to check systems. Found warning messages in the Ford app after incident, but nothing on dashboard to signal an issue.

Loss of braking. Note weather was cold in single digits fahrenheit and midly snowy. I drove my 2025 Ford Bronco that was purchased in octorber about 20 minutes to drop off my child at daycare. Going into the daycare I turned to slippery/4a mode. After about 5 minutes inside I pulled out and switched back to normal/2h mode. Less than half a mile later I got multiple warnings that the brakes, ebb, collision detect, and abs had faulted, and I should service now. I only had the electronic parking brake available. I was able to use it and engine braking with my manual transmission to get to off the road to a parking lot, although I did also receive a parking brake overheat fault the turn before getting into the parking lot. I shut the vehicle off without the parking brake on. I turned it back on and the dash warning lights all disappeared after a few seconds. Brake function returned and I drove it to a Ford service center about 1 mile away. They were not able to reproduce the problem or find any dtcs. I did get notifications of some of the faults to my Ford app on my phone. I am uploading the redacted ro and screenshots of the Ford notifications. Losing braking obviously put myself and my passenger pregnant wife at risk. Thankfully I was moving at lower speeds on a flat section of road and not taking a highway exit at the time of failure.

I own a 2022 Ford Bronco. My vehicle has an electronic brake booster failure that causes multiple warning messages, brake system faults, and loss or reduction of brake assist. When this happens, the vehicle also prevents the 4-wheel drive system from engaging or switching modes. This is especially dangerous during winter conditions. When driving in snow or slippery conditions, I am unable to engage 4wd when it is needed most, while also experiencing brake system warnings. The vehicle becomes difficult to control and does not feel safe to drive. The dealership confirmed this is a known issue affecting multiple Ford Broncos and that the electronic brake booster part is currently back-ordered and unavailable. I was told many vehicles are affected, yet there is no recall for the 2022 model year, even though newer model years have a recall for the same component. This issue creates a serious safety risk due to impaired braking performance and inability to use 4-wheel drive in hazardous conditions. The vehicle had to be parked due to safety concerns. And the he issue happens intermittently, making it unpredictable.

When my brakes are cold and I stop on a hill. . . The brakes do not hold and the car moves about a foot forward. Then something kicks in and it jerks the car to a stop (all the while my foot is completely pressed down on the brake. No warning lamps, no lights, nothing. . . Just rolls when brake is completely applied. It only does this when the brakes are cold. After they warm up it doesn't do it anymore. The dealer has looked at it and couldn't replicate (because the brakes weren't cold) and told me to bring it back if it happens again. It happens every morning but by the time the dealer gets it it doesn't do it anymore. A plethora of Bronco owners are experiencing this same thing. Our thread on [xxx] is full of people experiencing the same thing. Some guy in canada said he had every brake part replaced and it still happened. Then they did some sort of software update and he hasn't experienced it since. Why is this update not available to all? this is a serious hazard! someone is going to get hurt! information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

On June 13, 2025 my 2022 Ford Bronco and was involved in a serious collision in which the airbags did not deploy, the emergency braking and forward collision warning did not activate either. The second vehicle was t-boned at an estimated speed at the point of impact was 45mph. Both vehicles were a total loss. The Bronco suffered a bent frame and the passenger door would not open. The repair estimate was in excess of $36,000. I have reported the concern to Ford motor company under case number cxh-04933824-c1c3g9. At the time of the accident, there were no open recalls, warnings or notifications affecting the airbags or other safety systems. The vehicle was as-delivered by Ford from the factory with all regular service conducted by the local Ford dealership.

Our family was traveling from lake george new york to boston MA on Wednesday March 11th. As we passed another vehicle in the far left lane on I-90 the vehicle bounced and we lost control of the backend of the vehicle and it "fish tailed" across the highway nearly causing a collision at 65 miles per hour. The anti-lock breaks were activated and we nearly collided with several cars but managed to pull into the emergency lane. The vehicle was not drivable after this incident because any pothole or bump on the highway, at speeds over 50 mph, made the rear of the vehicle very unstable. It will skid and sway. Our vehicle is now undrivable and Ford says the only available solution is a "buy back" program and a solution will not be available until q3 of 2025. This leaves us with a 4 year old vehicle with only 24k miles undrivable. This is not acceptable.

Claim # cas cxh-026-40233- pre- collision assist(pca) to whom it may concern please forward to customer services since they refused email. We have a 2024 in route to riverhead Ford and refuse to pay their $200 diagnosis fee on pca failure. Not in obd iii plug in diagnosis no way to check if functioning. Will be reported to NHTSA. My Broncos 2022 is still in bumper to plumber warrantee but recently with my key not administrator key noticed the pca was not functioning. On page 24 Bronco quick reference guide states in pertinent parts: " if your vehicle is rapidly approaching a stationary vehicle, vehicle traveling in the same direction as yours or a pedestrian within your driving path, the system is designed to provide three levels of functionality. Alert; brake support & active braking" while driving an speaking to a customer service agents I tested behind a benz at approximate 40 mph and deliberately move my Broncos my22 less that one car length or so. Nada! no display! to place a pedestrian in from to test the pca would be wrong. The limited express warrantee state no charge for warrantee service, yet a call to riverhead Ford service agent who stated a diagnosis charge of $200 or so for one hour. The warrantee also states that power up on line modem saves are updates are no charge. Ford three customer service read " non-warrantee" Ford policy , but refused to disclose where they found that statement in warrantee . ( attached download) further two supervisors read same "non-warrantee" Ford statement said I must pay $200 or more for electronic software/radar type rf signaling systems like proximity sensors for diagnosis purposes. A simple drive with a car in front should when switch by touch screen from high ,moderate or low should function and save lives. It failed that test. Previously, the system function ,when a driver cut dangerous in front of me and if function on screen and I immediately braked, no so today. A non- Ford check the display a.

Break pedal feels very mushy and no breaking effect , very dangerous on highway speed for my car and cars behind me. I went to different dealers for a fix ,they all says it is normal, but it is sure not normal, I had multiple close calls. Break feel is inconsistent everyday. When I apply the break lots of deadline and no breaking effect for first few inches also pedal sinking to floor, Ford and dealership are ignoring this serious safety concern. Kindly do the needful,thank you.

Emergency brake failure. I have a very slight slope on my driveway. My car rolled halfway down my driveway. I assumed I did something wrong although I knew I had the car in gear with the e brake on. Two hours later I came back from an errand parked on my driveway was sitting in my car and my car started rolling backwards. The car was off in gear with the e brake on. I videotaped this happening every 20 seconds the car with balance, and roll back an inch or two. After 4 1/2 minutes, the car rolled the rest of the way down my driveway until it hit the street where it was flat. The car was in gear turned off with the e brake on, and nothing stopped the car from rolling. I tried putting it in an out of gear as this was happening and stomping on the break and nothing happened. I tried several times until it came to a complete stop. I have reported this to Ford. They took a complaint they don’t know what to tell me to do. They don’t have any recalls on my vehicle. This happened two times in the day. The second time was much worse. There were children riding bikes in the street behind my vehicle. I don’t know if the safe to drive this vehicle and the dealer is not able to give me any information. Ford customer service is not able to give me any information. I have video of this. I am not able to upload it to this site. I can email it or any other way that you would prefer.
