Owner complaint summary

When the Vehicle is put into Neutral Tow Mode and Towed behind a vehicle while using a supplemental braking system. The Bronco's Brake system becomes intermittently Active. Causing the slightest pressure to lock up the brakes. The Same issue as reported in. SSM 51415 . The Bronco power brake system is supposed to be de activated once it is put into neutral tow mode. Thus you set the supplemental brake system to respond as a vacuum brake system. So when the brake system on the Bronco becomes active during a stop it will lock up the wheels on the bronco and all four wheels skid. The brakes will stay locked up for what seems to be a long time but, may only be 10 or 15seconds to get them to release. Causing a dangerous traffic situation, huge stress on tires, towing equipment and the towing vehicle, The manufactures service refuses to any more troubleshooting saying the issue does not fall within the SSM 51415. Being this is a new 24 model year. They looked at the firmware and said i have the latest. I had this issue twice the same day. I have used my RVI supplemental brake system on several vehicles for thousands of miles without issue. Only with this bronco and my first 21 bronco have I had these kind of issues.
