When does it fail?
Of the 16 brakes complaints filed for the 2015 Lincoln MKZ, here's the actual mileage breakdown — failures cluster heaviest at 100,000-125,000 mi.

Each bar shows the share of total complaints filed at that mileage range. Peak failure window highlighted. Some owners report problems earlier; some make it well past 150,000 miles symptom-free. Maintenance habits and driving conditions shift the curve as much as mileage alone.
What stands out
Brakes accounts for 21% of all owner complaints filed against this vehicle, across 10 categories tracked.
No new NHTSA brakes complaint has been filed on this vehicle in over 7 years — the issue may be aging out of the active population.
The failure pattern owners describe
Buyer takeaway: Multiple 2015 Lincoln MKZ owners report brake hoses rupturing at relatively low mileage (59k–122k miles), causing sudden pedal collapse and loss of braking power in driving situations. NHTSA has issued recalls (23V162000, 22V011000) for hydraulic service brakes, but parts have been delayed; some owners report repeated failures even after repair.
Brake hose ruptures dominate complaints across this cluster. Owners describe brake hoses developing visible bubbles or splitting outright at mileages between 59,000 and 122,000 miles—well below typical hose life—releasing brake fluid and dropping the pedal to the floor. One owner found fluid pooled under the front passenger tire after the pedal went to the floor during a parking maneuver; Pep Boys found both front hoses bubbled and replaced them. Another owner experienced the same failure on the rear passenger hose at 99,200 miles after passing state inspection just months earlier. One case stands out: the driver-side brake line ruptured, then ruptured again after repair, nearly causing a highway collision.
Beyond outright rupture, owners report the brake pedal sinking to the floorboard during normal driving at speeds between 20 and 30 mph, with some cases showing repeated pedal drops that temporarily recover when pumped. Brake fluid warnings accompany these failures. A handful of complaints mention electronic parking brake engaging on its own while driving, locking the rear wheel and causing smoke—one owner replaced multiple components (caliper, actuator, rotor, pads, wheel sensor, bearing) without fixing it.
Lincoln and Ford issued recalls 23V162000 and 22V011000 for hydraulic service brakes, but owners report parts remain unavailable or delayed. The manufacturer directed at least one complainant to file an NHTSA complaint rather than address the failure directly.

Failure modes owners describe
Brake hose rupture
Front and rear brake hoses develop bubbles, split, or rupture completely, releasing brake fluid and causing sudden loss of braking power. Occurs on both front driver and front passenger sides, and rear passenger side. Owners report pedal going to the floor with loss of braking ability.
When: 59,000–122,000 miles; one case repeated rupture approximately 9 months after first occurrence at 70,000 miles
Symptoms owners cite: Brake pedal goes to the floor; Sudden loss of braking power; Brake fluid leaking under vehicle; No warning prior to failure; Service Brakes warning light illumination
Repairs/costs cited: Brake hoses replaced by independent mechanics and dealers; owners report hoses showed visible bubbling or splitting. One owner was given defective hoses and noted they should not have failed at that mileage and age.
Recalls/TSBs owners mention: NHTSA Campaign Numbers 23V162000 and 22V011000 issued for Service Brakes, Hydraulic; parts unavailable or delayed during recall. Manufacturer advised filing NHTSA complaint in at least one case.
Brake pedal unresponsiveness and floor-dropping
Brake pedal becomes unresponsive or drops to the floorboard when depressed while driving at normal speeds. Occurs intermittently and repeatedly, forcing driver to use emergency brake or coast to stop.
When: 99,200–117,000 miles; also reported at 115,000 miles with jerking
Symptoms owners cite: Brake pedal drops or sinks to the floorboard; Inability to stop vehicle immediately; Pedal may recover temporarily when pumped; Vehicle jerking during braking at various speeds; Brake fluid warning light illuminated
Repairs/costs cited: One case diagnosed as brake line rupture and repaired at dealer. In other cases, vehicle was not diagnosed or repaired at time of complaint.
Recalls/TSBs owners mention: NHTSA Campaign 23V162000 issued; in one instance, manufacturer advised filing NHTSA complaint rather than addressing failure directly.
Electronic parking brake malfunction
Electronic parking brake engages automatically while driving, locking the rear tire and causing it to smoke. Multiple replacement attempts of calipers, actuators, rotors, pads, wheel speed sensor, and bearing have not resolved the issue.
When: Timing not specified
Symptoms owners cite: Parking brake engages on its own while driving; Rear tire locks up; Tire smoke and friction from locked wheel; Potential fire or accident hazard
Repairs/costs cited: Replaced caliper, caliper actuator, rotor, brake pad, wheel speed sensor, and wheel bearing without resolution
Brake line rupture (recurrent)
Brake lines rupture repeatedly—driver side brake line ruptured for the second time, creating near-accident conditions. Owner states other MKZ owners report identical issue.
When: Mileage not specified; second rupture occurred after previous repair
Symptoms owners cite: Brake line rupture; Sudden loss of braking; Near-accident during highway driving; Driver forced to steer off road to avoid collision
Repairs/costs cited: Prior rupture was repaired; second rupture indicates defective replacement or systemic hose problem
Brake failure in winter conditions
Vehicle becomes unstable and uncontrollable on snow roads, with inability to stop or turn as needed. Brake pedal becomes unresponsive at normal speeds, trapping driver unable to stop at red light or turn at intersection.
When: Not specified; 12-mile trip reported
Symptoms owners cite: Inability to stop at red light; Inability to make left turn at low speeds; Vehicle instability on straight road; Unstable handling on snow

A quarter of owners report trouble before 59,000; a quarter make it past 115,000. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
What does it cost to fix?
Independent shops typically charge around $450 for brakes repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to brakes?
No active recalls currently cover brakes issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
