NHTSA Complaint #11506545 — 2015 FORD EXPLORER

I was driving my explorer in the snow and had put it in 4 wheel snow mode..as I was driving down a hill and began braking to make a turn the car slid a little bit and I thought nothing of it. I parked and drove again in snow mode a few miles and noticed that after I put the car back into regular drive the brake pedal seemed harder than usual. I parked, waited a minute, turned my car back on, touched the brake pedal and it seemed ok or better. A few hours later, I leave work and brakes seem harder than usual again. I had not put it in snow mode nor were any warning lights on. I only make it a mile or so when I find myself in the left lane of a highway attempting to drive up hill and my car barely goes 20mph. Something is seriously wrong at this point, with my 4 way flashers on, I had to navigate heavy rush hour traffic on a highway until I could find a safe place to pull off. Still no warning lights. I call my mechanic and he advised me to have it towed to his garage, Meineke. He is able to look at it the next day and finds the brakes are locked up and possibly something wrong with the 4 wheel drive. He's unable to determine for sure what is wrong and I have it towed again to the Ford Dealership. Ford Dealership has it for a few days and they had a tough time determining what was wrong. They checked codes and because no warning lights were on they didn't have much to go on. They determined it wasn't my 4 wheel drive but that it was my ABS module. They replaced it and flushed the fluid (which I was told was not the problem, it showed no signs of being compromised). They also replaced brakes rotors and calipers in the rear which I believe we're damaged in the ordeal. I do believe my safety and the safety of others was at risk. I should have seen a warning light to let me know something was wrong before I was on a highway.
