2015 Ford transit connect 150: while driving on the freeway 60-65 mph, the brakes seem to lock up without depressing the pedal, slowing to 40 mph and shaking uncontrollably. putting on the brake to exit the flow of traffic, braking caused the vehicle to shake even more finally by pumping the accelerator, the speed increased again. finally getting off of the freeway the brake pedal went to the floor. i had to pump the brake pedal until it finally reacted. less than a week later, getting on the freeway almost the exact thing happened. luckily i was a bit more prepared when i felt the shaking. today, driving the van back to our warehouse approx 15 miles on regular streets (not freeway driving) the brakes again went to the floor. master cylinder not leaking, brakes seem to be in good shape...but something is wrong we brought the vehicle to Sawgrass Ford in Sunrise Florida. they had it for over a month. they were unable to determine the problem and only made suggestions to completely change out all the brake components for $5-$6,000 but also said that they could not guarantee that this would fix the problem. the brakes were serviced approximately 6-7 months prior to these incidents I called Corporate Ford office. was told that the 2016 ford transit connect had Brake Hydrolic Control Unit recalls, but the 2015 doesn't have the recall listed. I also looking on manywebsites to verify any other2015/2016 problems with the brakes "locking up" or vehicle going into safe mode (another possibility) there were numerous complaints and concerns regarding 2016 & even 2017 situations very similar to what i went through. ford told me that model DV6Z2C405D BRAKE HYDROLIC CONTROL UNIT did not have an official recall. but that Ford stopped using that model and started using model EK4Z2C405A which was recalled and then replaced the recall with FK4Z2C405C. Seems like there may have been a problem with the 2015 model which caused the to change and with the 2016 model as well
