What stands out
Brakes accounts for 29% of all owner complaints filed against this vehicle, across 5 categories tracked.
The failure pattern owners describe
Buyer takeaway: 2017 Lincoln MKX models have documented brake hose failures in the rear suspension, typically around 70,000–90,000 miles, causing loss of braking power. Two factory recalls are outstanding, but parts remain unavailable or on back order, leaving many owners unable to complete repairs for months.
Owners of 2017 Lincoln MKX vehicles report rear brake hose rupture or failure, with the most common failure point being the rear passenger-side hose, though driver-side hoses have also ruptured. When a hose fails, brake fluid leaks onto the ground, and the brake system loses hydraulic pressure. Owners describe a soft or spongy brake pedal, followed by complete brake failure or the need to depress the pedal all the way to the floor to achieve any braking. The service brake or brake fluid warning light typically illuminates on the dashboard.
The actual brake failures reported occurred between 70,000 and approximately 90,779 miles. In these incidents, owners were unable to stop the vehicle normally and had to use parking brakes, coast downhill, or—in one case—jump a curb at 40 mph to avoid a collision. Independent mechanics confirmed hose rupture after visual inspection showed fluid pooling under the vehicle.
The brake system failures correspond to NHTSA Campaigns 20V469000 and 25V544000, both addressing hydraulic brake service issues. However, the dominant complaint across the cluster is parts unavailability: roughly half the narratives report that dealers have parts on back order or no ETA for arrival. Multiple owners state the manufacturer has exceeded reasonable timelines for recall completion. One owner reported Ford refused to cover collision damage caused by brake failure.

Failure modes owners describe
Rear brake hose rupture/failure
Brake hoses, typically on the rear axle (passenger or driver side), rupture or fail, allowing brake fluid to leak and causing partial or total brake loss. The soft, spongy brake pedal and need to depress it to the floor suggest hydraulic fluid loss.
When: 70,000–90,779 miles reported in narratives with actual failures
Symptoms owners cite: Soft or spongy brake pedal; Brake pedal depressed to floor with no response or delayed response; Visible brake fluid leaking under vehicle; Vehicle rolling forward or failing to stop completely; Service brake warning light illuminated; Loss of braking force
Repairs/costs cited: Replacement of rear brake hose(s). Two owners reported the failure occurred on both passenger and driver side hoses at different times, requiring multiple repairs. Parts availability has been a widespread issue preventing recall repairs.
Recalls/TSBs owners mention: NHTSA Campaign 20V469000 and 25V544000 (Service Brakes, Hydraulic) address rear brake hose failures. However, multiple owners report parts on back order or unavailable, delaying or preventing recall completion. One owner noted Ford refused payment for collision damage caused by brake failure.
Brake fluid loss and system pressure loss
Brake fluid leaks from hose failures result in loss of hydraulic pressure, making the brake system inoperative or severely degraded. Owners report needing to press the pedal to the floor to achieve any stopping force.
When: Occurs during normal driving; some failures noted around 70,000–90,000 miles
Symptoms owners cite: Brake fluid leak visible under vehicle when parked; Brake fluid warning light on dashboard; Complete brake failure requiring use of parking brake or curb to stop; Brakes require full pedal depression to operate
Repairs/costs cited: Brake fluid top-up or system bleed may be temporary; permanent repair requires hose replacement. One owner paid an independent shop for brake repair and realignment after jumping a curb to avoid collision.
Recalls/TSBs owners mention: NHTSA Campaigns 20V469000 and 25V544000 issued. Parts shortages have prevented recall completion for many owners. One owner reported Ford refused to pay for damage caused by brake failure and that Ford was nonresponsive regarding the claim.

I received a recalled noticed regarding a potential brake(s) failure. Currently the manufacture does not have sufficient parts and does not provide any ETA on when parts do become available. In the light of the situation, I would rather filed a complaint than risking my life or the lives of others due to the manufacture unable to provide the need parts to resolved this serious issue. I am…
