In January 2021, my vehicle had reached about 60,000 miles. As I was backing out of my driveway, I noticed multiple warning lights on the instrument panel and as I tried to stop the car discovered that the brakes were not working. I pulled the emergency brake handle and stopped the car. Had the car not stopped, I probably would not have avoided going into the street. I turned off and restarted the car but the brakes did not work (after you start the car, the abs light goes on and then the brake warning light goes on; the brakes only work a little near the floor). The vehicle was taken to the dealer and both the abs module and hydraulic control unit had to be replaced at a cost of about $3200. I noticed a recall for basically the same thing but the recall only went up to 2010.
The brake service light comes on periodically as well as the service advance trac message across the dashboard and the brakes don't function properly at this time preventing the vehicle from stopping while driving.
Brake light led assembly has 2 of 3 rows not functioning; Ford extended warranty on 2010 & '11 model year, but not 2012 for this failure. Seems a defect failure Ford has admitted on earlier model years, but does not want to admit it also happens on this model year. Guess they are using left over parts�. Lots of pictures of this problem on the web / internet. Passenger / right side brake lights.
