I am writing to file a formal safety complaint regarding the extreme delay in the recall remedy for my vehicle. Despite the recall being issued months ago, Ford Motor Company/Lincoln has failed to resolve this critical safety issue in a timely manner. Here are my vehicle details: Year/Make/Model: 2016 Lincoln MKX VIN [XXX] the federal safety agency Recall Number: 25V544 Manufacturer Recall Number: 25S87 Component Affected: Rear Flexible Brake Hoses Description of the Safety Concern: The recall notice explicitly states that a failure in the rear flexible brake hoses can lead to a loss of brake fluid, resulting in increased brake pedal travel and significantly increased stopping distances, which greatly elevates the risk of a crash. Recently, I have started experiencing a noticeable softening in the brake pedal ("increased pedal travel"), which makes driving the vehicle extremely hazardous. When I contacted my local Lincoln dealership, I was informed that they do not have the necessary parts in stock and could not provide a definitive timeline for the repair. As a consumer, I am being forced to drive a vehicle with a known, severe braking defect because the manufacturer has failed to supply the remedy parts. This is a direct threat to my life, my family’s safety, and the safety of others on the road. Furthermore, this prolonged delay is causing me significant financial hardship and stress. I urgently request the federal safety agency to intervene and hold Ford Motor Company accountable for expediting the parts distribution for this critical safety recall.

The contact owns a 2016 Lincoln MKX. The contact stated that while pulling into the ATM at approximately 10 MPH and depressing the brake pedal, the vehicle made an abnormal popping sound, and the brake warning light illuminated. The vehicle was driven to the residence. The vehicle was then driven to an independent mechanic, and was diagnosed with brake failure. The mechanic determined that the rear passenger’s side brake hose had ruptured, and the rear driver’s side brake hose needed to be replaced. The mechanic replaced both rear brake hoses, and the vehicle was repaired. The contact later received notification of the federal safety agency Campaign Number: 25V544000 (Service Brakes, Hydraulic); however, the part to do the recall repair was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was notified of the failure, and a request for reimbursement was made. The manufacturer informed the contact that the reimbursement would be provided once the part for the recall repair was available. The failure mileage was approximately 57,532.

While driving home from work during rush hour, a warning light illuminated on my dashboard and my vehicle suddenly lost braking ability. When I pressed the brake pedal, the vehicle did not slow or stop. I was forced to pull onto the shoulder of the road and pump the brake pedal extremely hard multiple times before the vehicle finally came to a stop. This occurred in heavy traffic and created an immediate and severe safety risk. The vehicle was towed to a dealership for inspection. I was informed that only a “temporary fix” could be performed, and I was required to pay approximately $500 for this repair in order to regain use of the vehicle. The vehicle has not received a permanent repair, and the dealership has taken several months without completing a permanent fix. I have also been waiting several months for reimbursement of the almost $500 paid for the temporary repair, with no resolution. I am concerned that I was charged for a temporary repair related to a serious safety failure and that continued delays in both reimbursement and permanent repair place me at ongoing risk. I am filing this complaint due to the dangerous nature of the brake failure, the lack of a permanent repair, the extended delay in resolving a critical safety issue, and the financial burden placed on me for a temporary solution.

Brake failure. Pedal drops, especially when ABS is activated. Dealer diagnosed ABS control module and HCU hydraulic leak. Parts for this are on back order per dealer leaving me with a dangerous driving situation or inability to use my vehicle. No warning lamp or message displays. The fact that the parts to fix a major safety item are not available is unacceptable.

My brakes have failed on this car three times. I had new front and back brakes installed on [XXX] mileage 44882. Again my brakes failed on [XXX] mileage 47626. A new brake booster was installed along with front brakes. Again on [XXX] brakes failed again and a brake booster and front brakes were installed. Mileage 54924. Today I was driving to my daughters house in Zanesville, Ohio and my brakes failed again. My car is still down in Zanesville because I could not drive it home. The mileage is 57000. Every time this happens I risk an accident. Even though the brake booster is covered by extended warranty, because Lincoln knows about this problem, I still have to pay for brakes and other cost. Isn't there anything that can be done about this? INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
