2011 Lincoln MKX Brakes Problems

Brake pedal went to the floor couldnt stop nearly crashed

I went to put Brakes on and didn't have any Brakes which created an accident. (9/27/25)

Twice while at a stop light with my foot on the brakes because of an incline, the engine sped up like it was grasping for air and the engine shut down. It started back each time, but the second time, my engine light came on. I called AAA since I am a member and went there for the repair. They diagnosed it as a brake booster problem and printed a copy of the Ford document sent to all US Ford and Lincoln Dealers regarding Customer Satisfaction Program 13N02, supplements 2 & 3. AAA suggested I take it to a Ford/Lincoln dealer and have the repair made under the recall. However, when I contacted Ford/Lincoln, they declined to even look at my car and said the recall was VIN specific and my car was not listed. Interestingly at the dealer and when I called and talked to several people at Ford and then Lincoln, they all asked my mileage. My mileage is 134,000, and 13N02 says it is effective up to 150,000 miles. The Ford document does not mention being VIN specific and my car is listed, a 2011 MKX with less than 150,000 miles. Your site says there are no open recalls for my car as well. Thanks [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2011 Lincoln MKX. The contact stated that while attempting to stop the vehicle, the brake pedal was depressed; however, the vehicle failed to respond as needed. The vehicle was driven to the dealer to be diagnosed. The contact was informed that the ABS system needed to be replaced. The vehicle was repaired; however, the failure persisted. The manufacturer was not notified of the failure. The failure mileage was approximately 60,000.

The brakes suddenly became very difficult to depress to make the vehicle come to a stop. Emergency repair was necessary, as driving to the dealer was unsafe. Brake booster was filled with fluid. The car then had to be towed to Dealer, where repair required replacement of Brake Booster, Master cylinder, and Booster vacuum hoses. There are recalls for this same make, model and year. Though my VIN does not come up in those vehicles covered by the recall, it is the EXACT same problem.

We had to replace the brake booster. Doing research online I saw that other Lincoln models in the same manufacturing year. A lot had recalls for the brake booster. Our mechanic suggested that we file a complaint with you because the recall should have covered all the Lincoln’s. Thank you

Brake pedal faded while in traffic. Was able to steer around other cars, got car to repair shop. Originally couldn't replicate issue. After attempting to drive car mechanic Was able to find problem. Diagnostic tests said master cylinder was bad. Replaced same and still had fading pedal. Diagnosed as hydraulic control unit (abs braking). Had vehicle towed to Ford Dealership for repairs. Replaced HCU no better. Then replaced flex lines at wheels, no better. Finally replaced master cylinder again, and finally fixed braking problems.

Brake pedal will go all the way to floor. Very soft pedal. For over a year we have talked to the dealers around Home. They all say Ford and Lincoln don’t have a problem. I talked to Lincoln concierge and she said if it became a safety issue to contact a dealer. It was still on the csp recall at the time. But I was told it expired. I paid to get the car worked on and had a pedal again. Now it’s back to the floor. Backing up a lot and putting on brakes doesn’t help this time. Now ford says yes they had a problem but it expired a year ago. I don’t drive this car every day. It now has 70700 miles. It had 52000 when I bought it 3 years ago. But to me brakes are important. I had to stop quickly in traffic and stopped in the intersection and luckily didn’t have an accident. It should be repaired without cost to me. It is a very serious problem. I’m also calling NTSB with this information to see how many crashes that there has been

A VALVE STICKS IN THE HYDRAULIC CONTROL UNIT OF THE ANTI LOCK BRAKE SYSTEM WHEN IT IS ACTIVATED WHEN HEAVY BRAKING THAT CREATED A VERY SOFT BRAKE PEDAL WHEN BRAKING BECAUSE BRAKE FLUID IS BEING DIVERTED THRU THE ABS SYSTEM WHEN IT SHOULDN'T BE. I NOTICED THERE WAS A SAFETY RECALL ON FORD, LINCOLN'S UP TO A 2010 MODEL. THERE NEEDS TO BE A RECALL ON MY MODEL VEHICLE ALSO.

ABS MODULE DUMP VALUE-MY BRAKES CAN BE VERY HARD TO STOP AND IT'S VERY UNCOMFORTABLE. I'M CONCERNED ABOUT MY SAFETY. I HAD NEW BRAKES AND ROTORS PUT ON ALL THE WAY AROUND AND I'M STILL HAVING ISSUES. I HAVE BEEN INFORMED THAT THIS IS A COMMON PROBLEM IN THE LINCOLN/FORD. I HAVE INVESTED ALOT OF MONEY IN THIS VEHICLE OVER TIME AND IT'S BECOMING MORE AND MORE FRUSTRATING THAT IT CONTINUE TO HAVE ISSUES. *TR
