Service Brakes Problems of Lincoln MKX - part 2

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.

The contact owns a 2013 Lincoln Mkx. The contact stated while driving 35 mph and attempting to decelerate, the brake pedal was depressed and went to the floorboard, but the vehicle failed to stop as needed. After pumping the brake pedal, the vehicle was able to come to a complete stop. No warning lights were illuminated. The vehicle was taken to an independent mechanic, who diagnosed a failure with the brake master cylinder. The vehicle was repaired, but the failure reoccurred. The vehicle was taken back to the independent mechanic, who diagnosed an additional failure with the abs. The vehicle was not repaired. The manufacturer was notified of the failure but referred the contact to the NHTSA hotline for assistance. The failure mileage was 126,000.

The contact owns a 2013 Lincoln Mkx. The contact stated that while driving at 35 mph, the brakes was firm causing more pressure to be put onto the brake when trying to slow down. The abs and traction control warning light was illuminated. The vehicle had not been diagnosed or repaired by an independent mechanic or dealer. The manufacturer was made aware of the failure and determined that the VIN was not included in a recall. The failure mileage was approximately 199,000.

The brake booster on this car is going bad. It is exactly the same part that was recalled on our daughter's 2013 Ford edge. There are no warning lamps or other feedback to the driver. It is an audible sound of air escaping that I recognized from her experience. It is not yet difficult to make the car stop, but, it is a significant concern. I first heard the issue in August of this year at just over 108,000 miles. It has not been inspected by a mechanic yet, I will be taking it in. This is a significant issue. It is continuous and I first thought it was in the air conditioning. My husband identified it as the same sound we heard on my daughter's edge.

The brake pedal is very difficult to depress. You have to push very hard for the car to come to a stop. The brakes do not work correctly causing not stopping when pressed. Safety issue for myself and others on the road. My car now has 122,890 miles on it. There was a recall that expired 2015. Never repaired under the recall, before I took ownership.

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.

The contact owns a 2011 Lincoln Mkx. The contact stated that while driving at an undisclosed speed, she depressed the brake pedal to stop the vehicle; however, the vehicle failed to stop as needed. The contact stated that she had to apply added pressure to the brake pedal causing the brake pedal to extend to the floorboard before the vehicle glide to a stop. No warning lights were illuminated. The vehicle was taken to the dealer where it was diagnosed that the brake booster had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure and the contact was informed that customer satisfaction program: 13n02 had expired. The contact was advised to call the NHTSA hotline for assistance. The failure mileage was approximately 190,000.

The contact stated that while her father was driving at an undisclosed speed, the brakes became inoperable; however, the contact stated that the father was able to safely drive the vehicle to the residence. The vehicle was driven to an independent mechanic, where it was diagnosed as a brake control module failure. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 50,000.

Brakes went out completely and it took several times to hit the brakes in order for you to stop. I almost had to choose hitting a pole to keep from endangering someone else. I could have lost my life. I am still frightened about this incident. After having the brake pads and rotors replaced, for $500, at jiffy lube, the vehicle still wouldn’t stop. I contacted Ford to inform of the issue and was informed that’s there two active recalls. After I found out there was a recall on the brake booster, I had the vehicle towed to Ford autonation, arlington, TX. They told me they were two weeks behind and would get to the vehicle ASAP. Waited over three weeks and not until the week of September 11, 2023, I was informed, that the recall expired in March 2023. I purchased vehicle in 2017. The incident occurred in July 2023. I informed them that this isn’t fair, because from research, several consumers are still complaining about the brake booster going out. I called Ford and was advised the same thing. I asked to speak with someone above and was informed, I’m it. He was the case manager. I called autonation back asked if they can give me a discount. Finally, I was advised repairs would go from $1413 to $865. I still feel the recall should be honored. I had no idea about this recall and it went out when it did. I guess Ford doesn’t care about their consumers life or the life of others that could have been hurt or killed. This is very poor customer service. So now, I have to spend more money which is now coming to a total of $1913, (includes brake pads/rotors), and Ford took approximately $600 off repairs, still leaving me with almost $900 out of pocket. Please assist me with my concern to this matter.

Without any warning light on dashboard, brake pedal on our 2013 Lincoln Mkx became very difficult to press. So difficult my wife is unable to do so at all. Takes an alarming amount of space to come to a complete stop. Very dangerous and almost caused an accident. A recall took place a few years back before we owned this vehicle (recall 13n02) and listed brake booster as the cause up through the 2013 model. For some reason our vehicle was not included. Regardless of if manufacturer says the problem was resolved by the time our vehicle was manufactured, that is clearly not the case. I have read countless testimonials from people in similar situations (same vehicle, year,and problem), so why is this not being addressed? why has this recall not been reopened? do you really need to wait until enough people have been effected, or enough accidents have been reported, or enough lives have been lost before this becomes something you'll address? this is extremely dangerous, happened with no warning, and I'll be damned if I'm going to wait on the sidelines until someone finally decides to pay attention. Somebody needs to do their damn job and get on this. For christ's sake, do better.

When braking there is no resistance on the brake pedal and is slow to break. Very scary when it randomly happens when driving and unable to quickly stop!.

The master cylinder for the brakes wen out an I replaced it on may 30th 2023 and today is June 15th and the same problem is happening.

Nhtsa recall number 13n02/ extended warranty coverage on brake booster.

Had to press brake pedal very hard, brakes were not working well. All pads/rotors were good. Had to bring it to a dealer and they said the brake booster had to be replaced. I noticed there was a recall on later model Mkxs but for some reason not the 2103 - it seems like the problem affects a lot of people though.

I had to get my brake booster replaced as it caused delayed braking almost causing me to crash.

I placed my foot on the brake to release the emergency brake. I heard a pop. The brake pedal immediately went to car floor. I didn’t know what it was initially but quickly realized something was wrong with my brakes when I was on the highway. When I tried to brake the pedal went to the floor and the car did not slow properly. I made it to the subdivision entrance when the low brake fluid indicator light came on. I made it home safely. When I stopped, smelled an odor (I was told it was likely brake fluid). I had it towed to the dealership. It was diagnosed the day after, informing me brake line had broke. I asked what was the cause and possibly wear and tear? he informed a weak spot in the line. I called Lincoln customer relations bc it’s a safety issue whether it is a new or old car under warranty to address my concerns. They explained I would have to pay since a warranty was not in place. As a customer, my car is under 100, 000 miles and I service it routinely. I am more concerned of this being an issue with safety than a warranty being in place. My son or myself could have been in a bad accident sustaining serious injuries with no brakes. The Lincoln rep implied my car was old, which is an insult. It’s only 7 years old. My 22 year old Toyota is still working and the brake line has never broke. I was informed by the service tech it is unusual to see this occur in the back brakes. The brake line/hose broke and the brake fluid leaked out. In my opinion, it’s a defect, durability, and a safety issue regardless of the age of my car. It is a much bigger problem that should be addressed. The customer service rep and her manager were eluding to their extended warranty program and they could not offer financial assistance. I have paid more for services when I feel it’s wear and tear. It is a safety issue with a possible defective part, which I should not be responsible to pay, regardless of a warranty being in place or not. Safety and durability are the bigger issue.

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.

The contact owns a 2017 Lincoln Mkx. The contact stated that while driving at an undisclosed speed with the brake pedal depressed to the floorboard, the vehicle failed to come to a complete stop. The contact stated that the brake pedal had to be manually moved to its normal resting position. Upon visual inspection, the contact observed brake fluid leaking from the rear brake lines and pooling underneath the vehicle. The brake fluid warning light was illuminated on the instrument panel prior to the failure being experienced. The vehicle was taken to an independent mechanic, who determined that the right rear brake hose had ruptured. The vehicle was repaired, but the failure later occurred in the left rear brake hose on June 20, 2023. After investigating the failure, the contact related it to NHTSA campaign number: 20v469000 (service brakes, hydraulics). The manufacturer was notified of the failure, and a case was opened. The failure mileage was 70,000.

2013 Lincoln Mkx, consumer writes in regard to defective abs hydraulic unit.

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.

I was driving and went to apply the brakes and they went almost to the floor, with very little braking ability. Thankfully I was going uphill and the car in front of me was not too close or I would have hit that car. And in a snowstorm to boot! I had no warning lights or any other indication that my brakes were going to suddenly go very soft. I got the car to my mechanic and he stated that the brake booster was leaking and needed to be replaced, and that is what caused the loss of pressure in the braking system. He said that there was a service bulletin #13n02 for that exact same problem for model years up to 2013, but because I had a 2014, the cost of the repair was not covered.

The contact owns a 2016 Lincoln Mkx. The contact stated that while driving at 45 mph and depressing the brake pedal, the brake assist, brake, traction control, and anti-skid warning lights illuminated. The auto-braking system became inoperable. The vehicle was taken to the local dealer, who was unable to determine the cause of the failure. The vehicle was not diagnosed or repaired. The vehicle was taken to an independent mechanic, who replaced the wheel hub, wheel sensor, lower control arm, and ball joint. Additionally, the mechanic informed the contact about several low voltage codes. The battery, alternator, and starter were working as designed, but there was low voltage. The manufacturer was contacted and referred the contact to the NHTSA hotline. The failure mileage was approximately 100,000.

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.

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.

First incident 10-15-2019 (purchased used vehicle 09-30-19) exiting freeway at 55mph and suddenly brakes stopped working( was able to pull aside) then brakes worked normal again. Took vehicle to check breaks and nothing wrong was found. Second incident 02-17-2020 driving son to school at 35mhp brakes stopped working while doing a right turn and ran over sidewalk to avoid hitting vehicle in front. Bumper got a little damage. Brakes check again and nothing was found. Third incident 05-15-2022 driving at 55mph on road and brakes stopped working before trying to stop at red light. Hit cement in middle of the road to avoid crashing. Used emergency brake and bumper was scratched. Turn on and off truck and brakes work normal again. June 22-2022 took to mechanic after being inspected at several places and found nothing wrong. Replaced brakes, front shocks and fluid. November 23-2022 driving on freeway at 70mph. Brakes failed again and almost crash with eighteen wheeler. Was able to hit the brakes with all my strength and merge into honking traffic to pull over on the freeway emergency lane. (could have been fatal) this incidents indicated are major but the problem has been in occurrence on and off randomly and frequently.

Have a hard brake pedal. U0401 code. Ford replaced battery. It got rid of code but still had a hard brake pedal. Ford replaced power assist unit. That fix the problem.

Brake booster faulty almost caused me to not to be able to come to a complete stop in traffic. My thoughts were that I needed to have brakes replaced. I did have front and back replaced. But braking are still the same the same . . Not coming to a complete stop, hissing sound.

While leaving out my driveway my brakes went straight to the floor before stopping. After I put the car in park and put my foot on the break again it was hard to push the brake pedal. I also hear air coming from the break pedal area. I had no warning and still do not have any warnings. I’ve noticed after reading a lot of reviews this seem to be a common problem and it’s not safe. Mileage 104,000.

We have had numerous failures in the braking system. This started with occasional spongy pedal issues that resulted in replacement of the brake booster. This started a two year long journey to repair brake issues. This has gone thru two of the most reputable auto mechanic shops in our area. We have gone thru three brake boosters, one master cylinder, and about to replace the second abs hydraulic unit. The abs hydraulic/module unit is the most frustrating because it is failing at such a rate the mechanics cannot get them new and we have had to use refurbished ones. This is a tremendous safety issue and we as consumers are working diligently to repair the issues. . . Only to have erratic unsafe braking conditions. This is a huge lawsuit waiting to happen if Ford/Lincoln does not address the issues and research a solution.

Brake booster problem. When looking online this is a common problem with my year make and model. This is very dangerous concern as I had my children in the car and my brakes would not stop no matter how hard I pressed my brakes. I was lucky there was no on coming traffic or I would have been in an accident.

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.
