2013 Lincoln Mkx

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.

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.

Our Lincoln MKX had a failure of its power brake booster showing no warning indicator light on the dashboard. The brakes felt like they had air in the lines and excessive pumping was needed to build pressure on the brake pads which eventually needed to be pushed close to the floor in order to stop. We made an appointment at the Ford Dealership. But, since it was a long distance from our home, and not to put us in danger of getting into an accident, we made it to the closest brake repair business we could find that was close to our home. It was found that our Power Brake Booster & Brake Master Cylinder needed to be replaced. We are the 2nd Owners of this Vehicle & we learned that there was an a Customer Satisfaction Program 13N02 - Supplement #1 for certain 2010-2013 Model Year MKX (& Edge) Vehicles that had an Extended Warranty Coverage on Brake Boosters. Our car VIN # falls in the timeframe of this. Moreover, when the Vehicle was purchased from the Ford/Lincoln Dealership, it had 33,341 miles on it & it now only has 51,920. The Customer Satisfaction Program repairs the issue with the power brake booster at no cost within 10 years & on cars up to 150,000 miles. We had to pay out of pocket for our repair & need assistance in getting reimbursement for this expense. This unsafe occurrence also lead to having to replace a Stop Lamp Switch on 02/4/22 which failed & we were charged again (in less than a month's time) for another switch. It was also found on that repair that the booster mount on the inside under the dashboard was not tight & it had a stripped fastener. Now it is being recommended that a removal of the brake booster & master cylinder be inspected for proper installation and that a cut-out of that stripped fastener be done. Access to this requires removal of the instrument panel & steering column to access the firewall to get to the fastener. Invoices related to all this are attached for review except for the last noted recommendations.
