When set in flat towing mode the Bronco-??s electronic brake boost (EBB) shuts off after 45 minutes or less. Once the EBB shuts off the Bronco-??s brakes, which are connected to the motorhome-??s brakes via an auxiliary brake system, no longer work properly and will not slow the Bronco. This failure then requires the motorhome-??s brakes to stop both the Bronco and the motorhome and creates a serious safety issue because: 1) Stopping distance increases dramatically. 2) The motorhome-??s brakes could fade, while descending grades, leading to total braking failure. Nearly all states require towed units in excess of 3,000# to have brakes but once the EBB shuts off the Bronco is in violation of these laws.

This vehicle is advertised as Flat Tow capable the 2.7 is equipped with electronic brake booster and when hooked up to rv that has a charge line that feeds the bronco with 13.5 volts continuously (as needed) the battery management system shuts off the electronic brake booster rendering the secondary brake system inoperable after 15 minutes in tow mode so the vehicle is set up with power assist brakes for the first 15 minutes then shuts down no matter what power supply is given creating the rv to do all the braking with no assist all while in tow mode

I purchased this vehicle to flat tow behind my motorhome. Ford states that the full size Broncos are flat tow capable, but unfortunately the braking system times out due to the electronic brake boost being on a timer. I have installed a supplemental braking unit to activate the brakes on the Bronco when being towed behind my motorhome. The braking system inoperative after the 45 minutes that the electronic brake booster times out. This is a huge safety concern due to the weight of the Bronco not slowing down as intended while being flat towed. This needs to be addressed with Ford Motor Company. I do know that I am not the only person who has experienced this issue and more people will continue to have this issue until a fix is implemented.

Recreational Flat Towing 2022 Ford Bronco with 2.7L V6 engine. After connecting my Bronco to the motorhome and using Ford instructions for putting it in the tow mode the following will occur: About 45 mins after turning the ignition off and closing the doors the EBB (Electronic Brake Boost) in the Bronco shuts down leaving the Bronco without any brake boost. This will leave the supplemental brake system ineffective. When first connecting the Bronco to the motorhome the brake boost is active and the supplemental brake system is functioning properly. After the boost shuts down the supplemental brake system may not apply enough force to the Bronco brakes to assist in stopping and the distance required to stop the motorhome and connected Bronco is increased. Should an incident occur that causes the Brono to become disconnected from the motorhome while under tow the automatic braking function of the supplemental braking system may experience the same issue and fail to safely stop the Bronco.

Flat Towing 2021 Ford Bronco with 2.7 V6 engine. After connecting my Bronco to the motorhome and putting it in the tow mode the following will occur. About 45 mins after turning the ignition off and closing the doors the EBB (Electronic Brake Boost) in the Bronco shuts down leaving the Bronco without any brake boost and leaves the supplemental brake system ineffective. When first connecting the Bronco to the motorhome the brake boost is active and the supplemental brake system must be set to match, or it will lock up the brakes on the Bronco when you stop. After the boost shuts down the supplemental brake system cannot apply enough force to the Bronco brakes to assist in stopping and all at once it takes a much greater distance to stop the motorhome than it did when the boost was working. This is my second complaint with no reply
