2013 LINCOLN MKX, CONSUMER WRITES IN REGARD TO DEFECTIVE ABS HYDRAULIC UNIT.
When stepping on the brake pedal about four months ago, it traveled nearly to the floor with correspondingly poor breaking but better than nil. Although it could be pumped up a bit to improve stopping it would continue to travel toward the floor. There was not room between the floor and pedal for the toe of my shoe. It was re…

When stepping on the brake pedal about four months ago, it traveled nearly to the floor with correspondingly poor breaking but better than nil. Although it could be pumped up a bit to improve stopping it would continue to travel toward the floor. There was not room between the floor and pedal for the toe of my shoe. It was repaired with parts that were not Ford a Lincoln OEM. Two months later, it happened again and was repaired with OEM booster and master cylinder. It has again happened in Jan 2022 with about 130,000 miles. I’ve read some of the issues with the booster but this has defied competent, hopefully competent, technicians on two prior occasions.

Brake Booster faulty almost caused me to not to be able to come to a complete stop in traffic. My thoughts were that I needed to have brakes replaced. I did have front and back replaced. But braking are still the same the same ..not coming to a complete stop, hissing sound.
The Brake Booster on my vehicle failed. I had it replaced and two years later it failed again. Many owners of the 2013 Lincoln MKX have this same issue. This is very dangerous and it putting my families and others lives in danger if my brakes were to completely fail while driving down the highway. There should be some kind of re…

The Brake Booster on my vehicle failed. I had it replaced and two years later it failed again. Many owners of the 2013 Lincoln MKX have this same issue. This is very dangerous and it putting my families and others lives in danger if my brakes were to completely fail while driving down the highway. There should be some kind of recall on this as I have seen thousands of complaints for the same thing on this exact thing.
The brake booster went out, as well as the PTU

Jul 2, 2014
Ford Motor Company (Ford) is recalling certain model year 2012-2014 Ford Edge and Lincoln MKX vehicles manufactured September 2, 2010, to November 30, 2013; 2013-2014 Ford Taurus and Lincoln MKS vehicles manufactured August 25, 2011, to November 30, 2013; and 2013-2014 Ford Flex and Lincoln MKT vehicles manufactured September 12, 2011, to November 30, 2013. In the affected vehicles, the halfshaft retention circlip may not have been properly installed, and as a result, the halfshaft may move outward and disengage from the linkshaft while driving and without prior warning.
Consequence & remedy
Consequence: If the halfshaft and linkshaft become disengaged while driving, power will no longer be transmitted to the wheels, increasing the risk of a vehicle crash. Additionally, if the parking brake is not applied before exiting the vehicle, the vehicle may roll away despite the transmission being placed in 'Park', increasing the risk of injury to exiting occupants and bystanders.
Remedy: Ford will notify owners, and dealers will inspect the vehicles to make sure that the halfshaft is properly retained. If it is not, dealers will replace the linkshaft and also replace the halfshaft if it shows evidence of spline damage, free of charge. The recall began on August 4, 2014. Owners may contact Ford customer service at 1-800-392-3673. Ford's number for this recall is 14S10.
