Upon exiting my garage I always stop to close the door. My driveway has incline. I begin to roll back, hit the breaks several times with no engagement, begin pumping the brake pedal several times, no response. Continued to roll in reverse going across the street and hit neighbor's park car in their driveway. Police Officer noted that brake pedal was very low upon applying brakes and a hiss sound of like a vacuum or pressure lost. Reported a claim to insurance company. I never observed any indication of faults. Had truck toed to Greiner Ford to be inspected and or repaired. They said they could not find anything wrong with brake system or electronics. Since the incident I have reviewed by Ring camera video of that day and noticed that the DRL lights were flashing like a turn signal light which are not supposed to do. Truck is presently at Greiner Ford Collision Center for repair of damage to drive side rearend. I will have Greiner reinspect once collision damage is repaired and advise them of the flashing DRL's Other problems encountered prior to this incident: 1. Several times with adaptative cruise on and lane departure on there has been several notifications of cancelations were noted. 2. Several times horn has sounded when opening door with truck turned off. 3. Pre collision notification without anything in front of truck. I will also note that after receipt of new vehicle, approximately 1 to 2 months the truck was updated with new software.
