My 2012 Lincoln Mkx is experiencing an issue with the brakes making it almost impossible to stop. The brake pedal is requiring extreme force to stop and goes all the way to the floor, followed by a hissing airy sound. The vehicle was taken to the Lincoln dealer who diagnosed the issue as a brakes and charged me $900. After picking up the vehicle and test driving it, the problem persisted. After re-diagnosing they pointed the finger to a hydraulic control unit. This issue poses great danger and the inability to stop without literally standing and applying force to the brakes. I have had to stop driving the car because when coming to a stop at any speed, the force needed to stop and a couple close calls with ramming in the back of someone, the car is just too dangerous. Additionally, I've had other issues with this car where the trunk will not stay open. It does not detect a person putting things in the trunk and I've had to run and push it up to save a kid who was loading sports equipment.

When shutting passenger door latch, latch will not move to grip inner part of the door. This will cause the door to bounce back or not close. This usually occurs when existing or entering car. Open door warning will remain on until latch is properly hooked.

The driver door latch would say its till open when the door is closed. Had to repair it twice at the dealer. Now the right rear door has the same issue.

The driver's side door ajar lite stays on even with the door closed. This is a intermittent problem. Was fixed by the dealer on 07/3/2014 now it's happening again.

Driver door ajar warning light is on. Has been repaired once under warranty. When on, the door locks do not secure the vehicle should it be involved in an accident! appears to be a consistent problem with Ford but they are not willing to resolve the problem. A recall should mandidated.

When my car is turned on and stationary with all doors closed, the dash gives me a warning that says the driver side rear door is ajar, when again, it is closed.

Drivers side door latch mechanism has failed. The door open warning light on the dash stays on. Attempts to get it to go out have failed. The car dings the entire time while driving it. At night the overhead lights stay on and interfers with visibility. When car is parked the interior lights stay on, draining the battery due to the door open warning on the dash.

The rear passenger door latch mechanism closed without the door actually being closed. This caused a false positive condition for the "door ajar" warning system. I thought that the door was secure, however the door was in fact not latched to the vehicle. My eight year old daughter was sitting in the seat. Were it not for the perception of my wife who suspected that the door was insecure I would have been driving with a door that would open while the car was moving. This false positive condition is caused by the fact that Ford has placed the sensor that tests for the door being closed on the latch mechanism rather than on the vehicle body. As our circumstances demonstrate the simple fact of the door latch being closed does not insure that the door is actually secured to the vehicle body. While no injuries occurred in our incident the potential for a serious injury is obvious. Had the door actually opened my child may have easily fallen out of a moving vehicle. The driver of the car must know with absolute certainty that all doors are truly secured. Testing the latch for being closed is not a sufficient test for the closure of the doors.
