2014 LINCOLN MKX Complaints

In 2021 I took vehicle in for intermittent soft brakes where the pedal would suddenly sink to the floor. Dealer replaced brake booster under warranty. Issue was still intermittent and 2 months into driving after the booster was replaced I suddenly lost all brakes. Took vehicle to dealer and now I am out of warranty and they claim there is a bad Hydraulic Control Unit (HCU) for the ABS system. Said there’s nothing they can do and it’s a separate issue even though it’s the same issue they failed to correct previously. The part number is DT4Z-2C215-A. I believe this is a replacement part for the obsolete BT4Z-2C215-A. The dealer is now quoting me $2000 for the fox and said it’s very common issue. Looking at other safety bulletins the year of my vehicle wasn’t included and believe it was either cut off at 2010/2011’s. But if most vehicles still have this issue 2012-2015 then why were they not included in the safety recall. I believe losing brakes warrants a recall especially sudden intermittent loss. Luckily the times I’ve lost my brakes I wasn’t on the freeway or in bumper to bumper traffic where I needed them.

on or about dec 24, 2022 while driving my brakes would not engage the pedal went to the floodboard. Mechanic inspection of my vehicle found that the control assy -ABS Hydraulics had failed . This was the 3rd incident the mechanic had found in the last month. Ford motor has acknowledged the problem but no parts are available. Over 900 customers are waiting for parts since the beginning of December 2022 (that we know of). There is no estimate time of when this part will be available and many vehicles to include mine are on the road with improperly working brakes.

In 2021 had an issue with brakes failing and becoming unresponsive/difficult to press almost causing a crash. Vehicle was inspected and the dealer replaced the brake booster and a vaccum line. This didn’t fix the issue. Recently had the same problem occur again where the brakes are intermittent and sometimes become soft and sink to the floor while driving. Apparently a bunch of people have been having this issue and the fix for it is to put your vehicle into reverse going 20mph and to slam on the brakes several times until the brakes become firm. Apparently there must be an issue with the ABS/HCU having a valve stick. Have seen Ford and Lincoln recall older cars up to 2010 in the past few years for DOT 3 causing corrosion to cause valve in HCU to stick. Remedy had dealer flush DOT 3 brake fluid and put DOT 4 and change HCU and master cylinder cap to say DOT 4 fluid. No recalls for my 2014 but I believe this is definitely a safety issue that should be addressed. https://m.youtube.com/watch?v=EqIkUE46Kvk

VEHICLE STATES THAT IT IS NOT IN PARK EVEN THOUGH THE GEAR SHIFT IS CLEARLY IN PARK. PASSENGER SIDE CLIMATE CONTROL TURNS ITSELF TO LOWEST TEMP. FOGS WINDSHIELD BECAUSE OF PASSENGER SIDE CLIMATE CONTROL ISSUE. DRIVER SIDE DOOR SAYS AJAR EVEN THOUGH DOOR IS CLOSED.

SPORADICALLY GET A MESSAGE THAT THE DRIVER FROM DOOR IS AJAR WHEN IT IS CLOSED. ALSO, GET A MESSAGE THAT TRANSMISSION NOT IN PARK WHEN THE SHIFTER IS IN PARK, MORE RECENTLY I HAVE ALSO GOTTEN THIS MESSAGE WHEN I START MY VEHICLE AND PUT IN DRIVE. SO FAR I HAVE BEEN ABLE TO GET BOTH MESSAGES TO GO AWAY BY OPENING AND SHUTTING THE DOOR A FEW TIMES(FOR THE DOOR AJAR MESSAGE) AND TURNING THE VEHICLE OFF AND BACK ON(THIS SOMETIMES TAKES 3 OR 4 TRIES, FOR THE TRANSMISSION NOT IN PARK MESSAGE). *TR

THE DRIVERS DOOR AJAR SENSOR IS NOT WORKING CORRECTLY. THE DOOR SENSOR ON THE DASH SHOWS AJAR WHEN THE DOOR IS ACTUALLY CLOSED. IT WORKS INTERMITTENTLY. CAUSES A DRAIN ON THE BATTERY. *TR

PUT CAR IN PARK AND RECEIVED A MESSAGE ON THE DASH SAYING "TRANSMISSION NOT IN PARK" BUT THE GEAR SHIFT WAS IN PARK.

I HAD NOTICED A WEEK PRIOR TO DRIVING TO WORK EVERYDAY THAT MY BRAKES WERE SOMETIMES GOING TO THE FLOOR AND SOMETIMES STOPPING ALL THE WAY UP MAKING THE PEDAL HARD TO PUSH. I DRIVE 20 MILES BOTH DIRECTIONS DAILY SO I AM ON THE HIGHWAY TO WORK. ON A MONDAY MORNING I EXITED OFF THE INTERSTATE AND I HAD NO BRAKES THEY WENT ALL THE WAY TO THE FLOOR SO I IMMEDIATELY DROVE IT TO THE NEAREST BRAKE REPAIR SHOP JUST DOWN THE STREET FROM WHERE I WORK. I HAD JUST HAD MY CAR AT THE DEALERSHIP ON FRIDAY PRIOR TO THE HAPPENING ON MONDAY FOR A COMPLETE SERVICE. THE BRAKE SERVICE REPAIR SHOP CALLED AND SAID IT WAS THE BRAKE BOOSTER AND THAT WAS HAPPENING TO SEVERAL OF THE FORD EDGES AND MY LINCOLN MKX IS ON THE SAME MAKE AS THE FORD EDGE. I CALLED LINCOLN GOT A CUSTOMER SERVICE REP AND HE SAID IT IS NOT COVERED. YOU ARE OUT OF WARRANTY SO I ASKED HIM TO CHECK IF THEY HAD HAD ANY PROBLEMS WITH IT. HE TOLD ME NO. I JUST LEARNED THIS WEEK FROM A REPAIR SHOP LOCALLY THAT THE BRAKE BOOSTERS WERE ON RECALL AND THEY SHOULD HAVE TOLD ME THAT. I ALSO CALLED LINCOLN AGAIN AND QUESTIONED THEM SHE SAID THEY HAD NO RECORD OF ME CALLING. I TOLD THEM YOU MIGHT NOT HAVE RECORDS BUT I DID MAKE THE CALL AND MY CAR SHOULD HAVE BEEN ON THE RECALL LIST. I HAVE OWNED SEVERAL FORD VEHICLES AND A BREAK BOOSTER HAS NEVER GONE OUT ON ANY OF MY VEHICLES. THIS IS A BAD MANUFACTURED PRODUCT AND I COULD HAVE BEEN KILLED IN AN ACCIDENT BECAUSE IT BROKE. THE REPAIR SHOP I TOOK IT TO SAID YOU CAN NO DRIVE THIS CAR. I RECEIVED A DEFECTIVE PART ON MY CAR AND THEY SHOULD HAVE RECALLED IT AND REPLACED IT BY LINCOLN. THEY ALSO TOLD ME BECAUSE I DIDN'T TAKE IT TO A DEALERSHIP THAT IT WAS NOT COVERED BUT I COULD NOT GET IT TO A DEALERSHIP BECAUSE I HAD NOT BREAKS. THEY SHOULD HAVE TOLD ME THAT WHEN I CALLED LINCOLN THE DAY IT BROKE BUT THEY DIDN'T. I FEEL LIKE THEY SHOULD REFUND THE EXPENSE FOR THIS REPAIRS
