Abs Brake Fail problems of the 2017 Ford F-250

While traveling at 35-40 mph in a turn lane, a vehicle moved into my lane from a shopping center between 2 cars stopped in the non-turn lanes who were waiting for the light ahead of them to change. This required me to make an emergency stop. The truck's abs system failed to initiate and the wheels did not lock up. Luckily, I managed to avoid hitting the errant vehicle. I took the truck to the dealer for service the following day and complained about the lack of abs. They kept the truck, test drove it and returned it to me with the notation that the truck's brakes are "normal. " I questioned why the abs didn't engage and was told that the weight of the truck precludes this from happening. Same reason for the lack of the wheels locking up. The service adviser furthermore stated that "that this was the way are engineered. " if this is true, then there is a serious problem with all super duty Fords out there and I might add all lighter trucks loaded anywhere close to their gvwr.
