   Recalled master cylinder brake booster was repaired at the dealership under the recall approx 4 or 5 years ago. The same issue has began again. Out of nowhere while braking, the pedal will become soft and press to the floor. During this time, the car will not slow down. This is resembling a defective part.

   Entering I-294 express ramp, vehicle was not accelerating beyond 40mph. then as I entered highway it shut down completely. I coasted to the right shoulder. The dash displayed a "low oil pressure" alert. So I did not attempt to restart the car. When I had it towed home, I checked the oil level and it was full. Nothing like this happened before. The vehicle is almost 12 years old with 167,000 miles. Had this happened in traffic on the expy, I could have been creamed by other cars or a truck. I am going to the dealer today to investigate but this seems like an anomaly where the engine shuts down because the computer thinks there is a catastrophic failure that is not really happening.

   I am having issues with my touch screen. My screen will go black every other week, for about a day and the the SNYC will update. This time, it’s been over a week, and the screen is still black. I have tried changing fuses to no avail. Also, the rear camera does not work. Along with the blind spot warning or the rear cross traffic warning. How should I proceed? I believe it may be a faulty chip in the computer board.

    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

    The braking system failed to adequately stop the car. In contacting the Lincoln Customer Service, this failure mode is associated with a Lincoln Customer program # 13N02. This program has a 10 years or 150000 miles limit for repair. The vehicle (MKX - 2012) has 65000 miles and was purchased 12/20/2011. It is 1 month out of the defined period. The car has only been driven a few hundred miles since 2020 due to illness and death of the owners. The brake system is a safety device and should not be considered a "Customer Care" program with limits as noted above. The failure of a breaking system will cause potential personal injury including death and should be reconsidered as a safety recall or the program should be extended. The incident of a major traffic accident on the highway was avoided that would have involved multiple cars if not taking evasive action in the median. The problem was confirmed by a dealer, verbally given the operation of the brake system. There were no warning lamps or any other indication prior to the incident. The VIN: [XXX] Thank you for your follow-up of this situation. [XXX], [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

    I have a 2012 Lincoln MKX and a piece of the transmission broke off while I was driving on the highway at night. I was able to get the vehicle to the shoulder but this could have caused a serious accident even resulting in fatalities. I have contacted the dealership but he is not cooperating and says that he is going to do nothing about it. I have an estimate from the repair where I had to have the vehicle towed. There were no type of warning lights at all on the dash board.

    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.

    I was driving and when I pressed on the brake, the pedal went far down and had no indication of the care stopping. It did, but it took a long time to brake. I took it for repair at Firestone, because my dealer warranty was expired. However, the Firestone let me know there is a booster brake replacement letter; the number of the recall is: 13N02. My car still qualifies as it is under 150,000 miles. The dealership repair denies my car is eligible; the main Lincoln office customer service representative also denied my car based on the vin. Is this correct? The letter of Customer Satisfaction Warranty shoes no exception based on vin?
