lOSS OF PRESSURE IN BRAKES AND FUEL FOOT PEDALS AFTER HITTING A POTHOLE. PRESSURE WAS SO LOW IN BRAKES I HAD TO PRESS BRAKE PEDAL TO FLOOR TO COME TO A JERKING STOP. IT FELT AS IF THERE WAS NO BRAKE AT ALL AS IT WAS SLOW TO BRAKE COMING TO AN ABRUPT STOP ONCE PEDAL FLOORED. I DO NOT HAVE DOCUMENTATION FROM SERVICE CENTER AS I HAVE NOT HAD IT LOOKED AT SINCE THE ISSUE HAPPENED YESTERDAY MORNING, AND I HAVE NO POLICE REPORT AT THIS TIME AS THERE WAS NO CRASH.

While driving on Sept 22 2023 I hit a pothole and immediately felt a change in the pressure in the gas pedal, upon braking I noticed a loss of pressure in the brake system. Vehicle was slow to respond to applicsation of brake pedal to where I had to move my seaty forward so that I could depress the pedal to the floor ( im 4'10" and could not apply the brake to the degree needed to stop my vehicle from the seat position I usually drive in). When pressing the brake pedal it felt as if it wanted to engage the ABS system but was not doing so and I would have to press the pedal to the floor which then would bring me to a jolting stop. I don't know how to explain it but there was also a differnce in the feeling of pressure when pushing on the gas pedal so whatever happened affected pressure in both the fuel and brake syatem foot pedals. I have not had the vehicle inspected as of writing this, nor have I reported it to Police as I did not experience a collisionbeing that it happened a short distance from my house abnd the vehicle has not been driven since the issue began yesterday morning Sept 22 2023.

Lately when I put the car in park it still beeps and say place in park. I have to take it in and out of park to get it to know that it is in park. the other day I put it in park and got out of the car with it still running and then it started rolling up the driveway. it was in the park position but it was moving up the hill like it was in reverse

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.

The contact owns a 2013 Lincoln MKX. The contact stated that while driving at approximately 60 MPH, the brake pedal was depressed and traveled to the floorboard. In addition, the brake pedal needed to be pumped several times for the brakes to operate. The failure recurred three times. The vehicle was taken to the dealer and then to an independent mechanic where the failure was undetermined. The vehicle was taken to the dealer where a diagnostic test was not performed. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 45,000.
