While applying brakes coming to a stop light, the vehicle gave a message stating service brakes. The brakes still felt normal. Then after a few minutes, the brakes felt like they suddenly stopped working and then the rear tires started locking up and releasing. The frong brakes felt like they were not working at all. Stopping distance approximately tripled and not really any way to adjust braking pressure. Releasing the pedal would give a 2ish second delay before the brakes would reapply upon hitting the pedal again, and withing 1 second would lock up the rear brakes again, starting the cycle over again. Took approximately 3 applications to fully stop in a safe manner. Luckily I was already driving slow due to the warning and was able stop before hitting the car in front. Was driving approximately 30 mph when this happened. Under normal circumstances and driving distances this would have not been possible. The car was taken to the Ford. They determined there was internal failure in the Electronic Brake Booster. The fix was to replace the full assembly (EBB, ABS, etc), and flush the brake fluid. Along with diagnostics of the issue, the cost was $4,100.87 to fix. Since replacing the EBB assembly, the problem has gone away. There were no other indictions of an issue before this happened. I know other Explorer years, and other models that use this same component have been recalled for similar issues as well, and think there is a issue with this module as well.

Vibration: First use of the day, at about 35 MPH vehicle exhibits vibration throughout, especially around 40-41mph. Felt in steering wheel, seat, and with a loud rumble often heard. Has been since car was new. Has a vibration in rear view mirror at highway speeds. Goes away after driving for 15 miles or so, and at least a half hour. Returns after vehicle cools off. Cruise control: Adaptive cruise sometimes causes extreme braking at highway speeds for no reason. This happened while driving past a vehicle on Alligator alley causing all my passengers to comment, even though I had not touched the brake. Happened again 10/28 on 75 coming down from Sarasota. Braking: ABS engages on dry roads, especially when turning, for example into a driveway, but it cold be just a normal stop for a traffic light. The brakes also “grab” when coming to final stop, causing the car to stop suddenly
