I tried to start my car this morning. It would not start. There was a loud popping noise, the headlights started flashing and a red box popped up on the control panel with the words brake failure. It was fine yesterday. There is a recall on the brake hoses. I called the dealership I bought the car from, Oxmoor Ford, Louisville, Ky and they said they don’t service Lincoln products anymore and referred me to Bill Collins Ford. I called them this morning and they haven’t called me back. I do have AAA, so I can have the car towed to the dealership. I need my car, what do I do?

While driving, the right front brake hose ruptured, releasing a large amount of brake fluid, dropping the brake pedal to the floor and causing a sudden loss of braking power. I have the faulty hose in my possession. I was not able to brake while driving out of the mountains in Tennessee. My wife and I consider ourselves lucky to be alive. Had it happened minutes earlier, we would not be here to tell you about it or to show you the faulty part. The faulty hose was inspected and replaced by an auto mechanic. I advised our local Lincoln dealer/service and I also spoke to the Lincoln Concierge service about what should be considered an ongoing safety hazard. I am hoping to show it to you and anyone else that may be familiar with an identical issue regarding the Ford Edge/MKX version of the same brake hoses. There was no warning at all prior to the sudden loss of brakes.

I JUST HAD MY STATE INSPECTION IN JAN. ON 3.28.20, I GOT INTO THE CAR, STARTED IT. I PLACED THE CAR IN REVERSE, PUSHED ON THE BRAKE PEDAL AS I PARK ON A SLIGHT INCLINE. I FELT A RESISTANCE AND THE PEDAL WENT TO THE FLOOR. THE VEHICLE DID STOP. UNSURE OF WHAT HAPPENED, I PUT IT IN PARK AND I APPLIED THE EMERGENCY BRAKE. AS I WAS PARTIALLY IN TRAFFIC PUT IT IN DRIVE TO GO FORWARD AND USED THE EMERGENCY BRAKE AGAIN, PUT IT IN PARK. TRIED BRAKE PEDAL AGAIN, IT PUMPED TO NOR MALFUNCTIONED POSITION. THINKING IT WAS A SYSTEM GLITCH, I TRIED AGAIN. WHEN I PUSHED THE BRAKE THIS TIME TO PLACE IT IN REVERSE, IT WENT TO THE FLOOR AGAIN. TURNED CAR OFF AND EXITED TO LOOK. SAW BRAKE FLUID ON THE GROUND AROUND THE FRONT PASSENGER TIRE. CALLED FOR A FLAT BED TOW. IT WENT TO PEP BOYS. THEY SAID THE FRONT PASSENGER BRAKE HOSE HAD BUBBLED AND SPLIT. I REQUESTED THEY CHECK ALL THE HOSES. THE FRONT DRIVER ALSO HAD A BUBBLE DEFECT. THEY REPLACED BOTH. I AM THANKFUL IT HAPPENED AS IT DID BECAUSE I GO DOWN A STEEP, DOWNHILL MOUNTAIN BACK ROAD TO GO HOME. THEY MADE THE REPAIRS AND CHECKED EVERYTHING IN THE SYSTEM, ALL ELSE IS WELL. THEY GAVE ME THE HOSES BECAUSE THEY SAID FOR THE MILEAGE AND AGE, THIS SHOULD NOT HAVE HAPPENED. NOTHING WAS NOTED AT THE TIME OF INSPECTION EITHER, AT THE SAME PLACE. I FOUND NO RECALL OR BULLETIN ON THIS. IT NEEDS INVESTIGATING BEFORE THERE IS A TRAGEDY.

I WASN'T ABLE TO STOP ON A RED LIGHT , AND I WASN'T ABLE TO MAKE A LEFT TURN, TWICE ON ONE 12 MILES TRIP. FIRST I DROVE WITH LITTLE SPEED NO MORE THAN 25 MILES AN HOUR, AFTER, ON SECOND INTERSECTION I STAYED ON A RED LIGHT AND STARTED MY TURNING FROM 0 SPEED.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2015 Lincoln Mkz Hev verdict →
