My brakes stopped working with no warning while driving. All of the brake related lights came on and the pedal went to the floor and I was unable to stop the car. This is a safety issue for the driver and everyone else because there seems to be no warning that the brakes will stop working. I brought the vehicle into a repair shop and they could not find anything wrong with the brakes, however there are multiple reports on this website of the very same issue that I dealt with. When attempting to report this to the Ford/Lincoln manufacturing, they stated that their system was down and they had no way of taking a report. This is very dangerous and needs to be addressed.
Breaks suddenly stopped working. Lights on dash including abs came on. Car would not stop until pedal pressed almost to floor. Almost as quickly it started working again and our mechanic can not reproduce it. There a number (17) of other complaints describing the problem with more drama. (see 11403440 for one) incident happened three times, twice going forward and once backing up. Please recall this quickly before someone is killed.
