Around September 2019, the brake booster on my Lincoln Mkx began failing, getting worse and worse quickly. It got to the point that I had to almost stand with two feet on the brake to make the car stop. (which was frightening when I was trying to stop the car before hitting the one in front of me, even thought I was only going about 30-40 mph). When I pressed the brake the pedal would slightly depress, then hiss and then with my increased pressure on the brake pedal it would depress further, seemingly close to the car floor. The car became increasingly difficult to stop. My mechanic said my brake booster needed replaced and that there was an extended warranty on the part. I purchased the car used. I called Ford and gave them my VIN number and they said that the bad parts stopped being used in March of 2013 and that my car was produced in may of 2013. Well obviously since I had the exact same problem as that which was the subject of the recall, the bad part was used in my car as well. Ford opened a case (#24559511K4) but refused to cover the repair. I had to pay out of pocket to have my car repaired since it was dangerous to continue to drive. The mileage on the car at the time of repair in October 2019 was 110,334. I believe the Ford should reimburse me for the cost of the repair.

The vehicle was in motion when brake pressure was lost as I was turning right. I have to push the brake all the way into the floor board. This has happened three other times, where the brakes eventually reset themselves to where I gently push down on the brake pedal. At this moment I have to push hard on the brake pedal all the way down to the floor board.

There has been a hissing noise made while depressing the brake pedal for several months. Lately, while pressing the brake pedal, it feels 'spongy' without a noticeable effect on braking performance. Just recently, the effort required to stop the car has increased to the point that it feels like the power braking system is hardly assisting. This matches the description of field service action 13N02 issued by Ford/ Lincoln, which only applies to "certain" vehicles. However, upon contacting a local dealership and the nationwide call center it was discovered that this vehicle was excluded from the fsa. This is a potentially life threatening issue, especially if an individual did not have this serviced and relied solely on driving without power brakes. Ford/ Lincoln should not be able to pick and choose "certain 2010-2013 model year edge and Mkx vehicles" when it is apparent from reviewing Ford edge and Lincoln Mkx reports on carcomplains.com that both vehicles exhibit this issue frequently, and that Ford/ Lincoln have excluded numerous vehicles from repairs. The company is aware that an issue exists, but there are multiple instances of Ford/ Lincoln refusing to replace a faulty part that should last the life of a vehicle. It is unacceptable to allow a company to operate in this manner.

The contact owns a 2013 Lincoln Mkx. While driving 60 mph, the brakes failed. The contact drove to apple Ford shakopee (1624 weston ct, shakopee, mn 55379, (952) 445-2420) where it was diagnosed that the brake power booster malfunctioned and needed to be replaced; however, they did not have the part available. The dealer stated that the vehicle should not be driven because the brakes could fail completely. The vehicle was towed to another unknown Ford dealer and repaired at the contact's expense. The manufacturer stated that there were no recalls for the vehicle. The failure mileage was 38,700. Consumer says that failure is similar to the Ford edge which had a recall. Consumer made manufacturer aware of this connection, but they still refused assistance.

My vehicle's power shut down without any warning on busy city street (3 lane road). I was unable to steer or brake. I had to coast off the road until car stopped. Then I put it into park. It restarted and drove fine after the restart. Very scary. Thankful I wasn't driving 70 mph on busy interstate. Throttle body replaced recently as engine had been bucking and wasn't accelerating when gas pedal was depressed.

Someone at the company evidently does not understand the auto assembly process wherein the component suppliers are required to warehouse components and assemblies for just in time delivery to the assembly plants. Components and assemblies are stored and delivered as retrieved, not in order of manufacture, so the the last parts delivered may have been built months before delivery. By setting a deadline manufacture date of March 2013 for vacuum booster assembly you are assuming that all the defective parts have been purged form the system, when that is probably not the case. So my 2013 Lincoln Mkx #2lmdj6jk2db[xxx] could possibly have a vacuum booster assembly manufactured in 2012, yet your system refuses to allow replacement. This is totally unfair.

On July 18, 2019, the brakes on my 2013 Mkx suddenly became very stiff with poor braking while driving in town. I immediately took it to a local service center and was informed that there was a safety recall on the 2013 Mkx brakes and it was suggested I take it to the local Ford dealership. I went directly there (less than 1 mile) it was diagnosed by the service writer to be a defective brake booster (brake pedal stiff, then while pressing the pedal, it went to the floor, and a whistling noise was heard) I had the brake booster replaced the following day, however that was not the only problem. The brakes went from stiff with poor braking ability to absolutely no brakes at all. Informed that the part needed (ABS module) is on national backorder-none currently available in the United States. My car is still at the repair shop waiting for the necessary part to complete the brake job. Today's date is August 7, 2019. The part is on emergency order, there is no indication as to when the part will become available. I am stranded without a car. I have read several reports of exactly the same problem with the 2013 Lincoln Mkx brakes and some were recalled. I was informed that mine was manufactured in May 2013 and the recall only covered those manufactured through March 2013. I seems obvious to me that the problem with the brakes was not resolved at the manufacturing plant, or the exact same issue would not still be occurring. This is a serious safety issue. Do we have to wait till deaths and serious injuries occur before Ford company will do the right thing and recall all 2013 Lincoln Mkx. I had plans to drive myself and 2 grandsons 300 miles to the beach on July 19, we were all disappointed that our vacation had to be cancelled, but I shutter at the thought of driving on the interstate and suddenly having no brakes. Please do the right thing - recall 2013 Mkx

I was driving on interstate 69 in houston, Texas when I feel lt like the brake petal was hard to push and also heard a sound from the dash. This terrified me so I got off the freeway and immediately looked up brake check location to go get the brakes checked. I found one 8 miles away and drove there and explained to a technician what had happen. The technician got into my Lincoln and stepped on the brake pedal and said it's going all the way down to the floorboard and hard to push. And he asked me if it felt harder to push. I told him yes. He checked the brakes out and told me it was the brake booster. He said with only 41,700 miles he himself would take it back to the dealership. We don't live in houston, and we were on the way home from houston after my husband having surgery and I needed to get him home. We had no choice but to drive home. I drove in the middle lane at 55 mph and keeping a distance in front of me. When I would use the brake I would have to start braking way ahead when someone would cut I front if me because the brakes were barely working. I babied the brakes all our 4 hour drive home. Please inform me what can be done. This should not be happening to a vehicle with only 41,700 miles. We bought it used in 2017 after hurricane harvey. I'm thinking there was a recall on the braking system and it was never done by the prior owners and they decided to sell it. This should apply to the lemon law. Because we were sold a defective vehicle. We could have been killed driving on a busy interstate in houston tx. Terrifying driving home. I

Brake booster issue

- Florissant, MO, USA

I purchased this car in September 29, 2013, with 3 miles on it. It currently has just over 20,000 miles on it. The brake booster started hissing, squealing, when I depressed the brakes to start the car last week, but I thought it was because I had just washed the car. Now the car was just out of warranty. This should be covered under the warranty, but Lincoln wants $1,000 to repair.

While depressing the brake pedal, a hissing noise can be heard coming from the vehicle and the pedal effort required to stop the vehicle has become harder. While investigating this matter, my mechanic found a recall concerning the exact same issue I was having on the same exact make, model, and year as mine (recall number 13no2). When I went to the Ford service department, I was turned away as my VIN wasn't found under that recall even though they acknowledged that my vehicle was having the same issues as the recall stated for the exact same vehicle as mine.

Brake booster diaphragm leak, air hissing sound from brake booster. Ford has already issued 'customer satisfaction program' 13N02 regarding brake booster/master cylinder problem' "certain 2010-2013 model year edge and Mkx vehicles built at the Oakville assembly plant from May 3, 2010 through March 28, 2013. Affected vehicles are identified in oasis." Our Mkx was built in July of 2013 and is experiencing the same problem.
