Ford Bronco abs comes on

Filed May 26, 2026 · Brakes · AZ

There has been an SSM release by Ford (SSM 51415) acknowledging that 2021-2022 Bronco vehicles flat towed in neutral may experience inconsistent or unintended ABS (anti-lock brake) module activation while being towed. The ABS module exits sleep mode unexpectedly due to road vibration input during towing, which can cause brake drag or lockup while the vehicle is being flat towed behind a motorhome. This is a safety concern as unexpected braking of the towed vehicle can affect the towing vehicle's stability and control at highway speeds. The vehicle is being operated exactly as documented in the Ford owner's manual, which explicitly supports neutral flat towing. Ford has developed a software update to address this defect but is declining to cover it under warranty or goodwill, instead classifying it as non-covered maintenance. The issue has been confirmed by an authorized Ford dealership who identified SSM 51415 as applicable. A community workaround requiring removal of fuses 28 and 29 to disable the ABS pump has emerged among owners, indicating this is a widespread known issue affecting safety during a manufacturer-approved towing method. Ford should issue a TSB or recall and cover the software correction at no cost to owners.

When braking(going down hill) the Bronco comes to a complete stop and the brakes feel good. But a split second after the full stop, the truck starts to creep forward for about a foot and then you hear a "click noise" and the truck abruptly stops. This is a very scary feeling wondering if your gonna roll into cross traffic. This happens every morning(once every day) and the rest of the day the brakes feel good. This issue has been happening for the last 7 days. I made an appointment with Ford dealer to look at it. Service writer tried looking up any recalls or complaints on this issue and couldn't find anything? On the BroncoG6 forum online, there apparently are other Bronco owners complaining about the same issue. One owner (online) stated that the dealer reprogrammed the ABS system and his truck hasn't repeated the creep anymore. There haven't been any brake, ABS or any warning lamps at all when this happens. This really needs to be resolved before someone get injured.

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.

The contact owns a 2024 Ford Bronco. The contact stated that after parking and turning off the vehicle, the "Steering Assist Fault, Service Required" message was displayed. The message disappeared after restarting the vehicle. The vehicle was taken to the dealer, but the dealer was unable to duplicate the failure. The failure recurred while pressing the Auto Start/Stop button without depressing the brake pedal. The engine revved abnormally loud while the vehicle was parked. The messages "Steering Assist Fault, Service Required", "Pre-Collision Assist Not Available," and "Service Advancetrac" were displayed. The ABS and battery warning lights were illuminated.

Roadside Assistance arrived on the scene and the contact stated that when the tow truck driver started the vehicle, the messages and warning lights were no longer illuminated or displayed. The vehicle was towed back to the dealer, but the dealer was unable to duplicate the failure for the second time. The vehicle was not repaired.

Two different times, my brakes have lost power. Both times were at slower speeds while coasting. The first time a car pulled out in front of me (about 50 feet ahead) and even though I was only going about 15 miles per hour I was barely able to stop in time. When I hit the brake pedal it felt rock hard (like when you pump the brakes with the engine off). The pedal did not go to the floor or anything like that. It stayed high in the stroke. No ABS sensation or warning lights. The next time I hit the brakes they worked normally. I couldn't reproduce the problem until about 2 months later I was leaving work and was pulling up the street at about 5 miles per hour when it did the same thing. It was almost flat ground and It was all I could do to press the brake pedal hard enough to stop in time. The symptoms were the same as the first time. The moment I hit the brake pedal again, all was normal. The weather was warm both times. The dealer cannot reproduce the problem

Abs system worked intermittently. Brakes pulsated, and consumer had to jump the curb. Repair shop determined a module problem & repaired it. Subsequently, while consumer was going 15-20mph and pulling a boat, pressed on the brakes and ABS light came on. Consumer couldn't stop, and rearended vehicle in front. Consumer has been trying to get vehicle repaired; but, dealer didn't seem to have a remedy. *ak
