2012 Lincoln MKX: brake failure

Filed Oct 2, 2021 · Brakes · FL

I had to slam on the brakes due to a driver pulling out in front of me without looking. The brakes went to the floor and I had difficulty getting the car stopped. I took it in to my mechanic and they diagnosed as a master cylinder, which I had replaced 7 months prior for a similar incident. But, replacing the master cylinder didn’t solve the problem. After more work, they replaced the entire ABS system for the rear brakes ($1900). I drove it 3 times and the brakes locked up on their own while I was driving at 60 miles an hour. When we got to the side of the road, smoke was billowing out of the brakes and the car would not move even though we were pushing the gas. We had the car towed ($300) back to the mechanic. They said the brake fuel line had gotten clogged and the front master cylinder needed to be replaced ($900). Drove twice and same issue, this time smoke billowing out of rear brakes. All brake fluid has completely drained and car needs to be repaired again. It is not drivable, so we will have to have it towed again. I’m so frustrated because this is extremely dangerous and I am stuck with a vehicle that seems to be irreparable and not drivable. Shame on Ford for not recalling this when it is obviously such an issue.

Driving late at night from dinner, brakes failed. Took MKX to servicing dealer, replaced m/cyl problem still there, order brake controller two weeks ago, part on shortage no due date. Part fit alot of models and years. FMC should pay for parts, very safety failure, we live in rural area and have the car serviced at Ford/Lincoln. no warning lights

While driving on the highway, brake pedal goes to the floor board. Replaced rotors brake pads and calipers. A couple of weeks later, pedal goes to floorboard again. Replaced master cylinder, but was told it was probably the ABS booster. Needs to be a recall. This is the 60 th complaint. Also back up camera is upside down.

My 2012 lincoln mkx has a very low break pedal and is a result of the (hcu) hydraulic control unit. As my car's break pedal goes to the floor and it makes stopping the car almost impossible at any speed.this is very problematic for this year make and model.I am assuming ford will wait till someone gets seriously hurt or killed before they recall the problem.buyer beware stay away from this model and the majority of ford products. Still very confused as to how and why ford can get away with such a serious breaking problem with no recall since 2012.

When using the brakes the pedal goes all the way to the floor and stops slowly. This is done while driving regardless what speed. The brakes would return and go back out randomly. I have the brakes go out on highway and city street as well as in park or in gear. Brake booster recall was done and the problem persisted. Returned to lincoln and diagnostic was done stating needing to replace brake master cylinder and hydronic control. The hydronic control needs to be recalled. The price can go out without warning and cause vehicle not to stop.

The brakes on our 2012 lincoln mkx have without warning failed placing myself and my family at great risk. The sequence of the failure was a very stiff brake pedal immediately followed by a soft pedal that when depressed goes fully to the floor (endpoint of the brakes). In spite of being fully depressed braking is extremely minimal. There is no cabin warning of a system failure and the only method of knowing of this life critical system's failure is needing to use the brakes. This obviously places the occupants of the car and those innocently in the car's path at a heightened risk of death due to total brake failure. I have seen that this complaint is not isolated to our ford product but extremely prevalent to ford edge and lincoln mkx vehicles. While ford is supporting the issue through a warranty extension given the extreme danger presented by catastrophic brake failure such as this it seems prudent that the federal safety agency demand a recall of all vehicles that may be subject to this issue. Our vehicle has only 67,400 miles on it and is garage kept. Please take action to prevent tragedy!

Had brakes fixed during initial recall 4/17/2018. Was not notified of recall until brakes went out. Brakes failed again on 9/3/19. Prestige ford contacted twice with no return call. Is this going to be fixed at no charge due to manufacture failure? Only 3,300 miles put on car since brakes were fixed the first time. Vehical was moving and on highway braking to make turn. Brake petal went to the floor, car did not stop. Unable to drive at this point.

I noticed a few days ago when I was in traffic my brakes didn't want to hold. I pressed really hard and only then did my car stopped. I took it to a mechanic and he checked it out and said my brakes looked great. Two days ago I was driving and my car just shut off and the engine light came on. I took it to the ford dealer to have it checked out. I was told it was a faulty value and that my brakes were fine. When I went to leave the dealer my car shut off in the middle of the highway and my brakes failed I was thankful that there were no cars in front of me. I immediately turned around and went back to the dealer. The manager came and checked it out and he said the booster part of the brakes were defected and my car was still under warranty. The car is now in the shop. I noticed when I checked online that others have had the same issues. My fear was having an accident!

I drive a lincoln 2012 mkx. As I was driving down the road coming up to a major intersection my brakes failed. After vigorously pumping the brakes, I was finally able to come to a safe stop without an accident. As it turned out, the brakes had a defected power booster and I had to have this replaced. I have been in touch with lincoln and besides offering me an extra warranty they could not assist with getting me into another vehicle. I have had issues with this vehicle since it was purchasednew. The stick shift had to be replaced due to transmisson issue and not going into park, back hatch issues, software issues, radio issues, and the most recently a power steering hose leak, then this issue with the brakes. After the last issue I lost any comort level in the reliability of this vehicle.
