What stands out
All 2 active brakes recalls on this vehicle land at critical or severe — none classified moderate.
Brakes accounts for 21% of all owner complaints filed against this vehicle, across 10 categories tracked.
Ford Motor Company (Ford) is recalling certain 2014-2015 Fusion, Lincoln MKZ, and 2015 Mustang vehicles originally sold or ever registered, in Texas, Louisiana, Mississippi, Alabama, Florida, Georgia, South Carolina, North Carolina, Virginia and Hawaii
A separated brake pedal bumper can cause the brake lights to illuminate continuously, causing confusion to other drivers and increasing the risk of a crash. On automatic transmission vehicles, a missing brake pedal bumper can allow the driver to shift the vehicle out of the "PARK" position without depressing the brake, allowing the vehicle to rollaway, increasing the risk of injury.
Fix: Dealers will replace the brake pedal bumpers and clutch pedal bumpers, free of charge. Interim owner notification letters notifying owners of the safety risk were mailed on March 4, 2022. Owner notification letters were mailed on June 13, 2022. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 22S02.

Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering brakes on this vehicle — documented
repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall
(it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
Service BulletinSSM 51261Dec 2022
Some Ford and Lincoln vehicles may exhibit noise when the brakes are applied. When diagnosing and repairing brake noise conditions, use the Workshop Manual (WSM) and the appropriate pinpoint test in section 206-00. The brake rotors should only be machined if directed by the WSM because one or more of the following conditions are present on the braking surface: scoring, excessive corrosion/rust or pitting, bluing/discoloration and/or heat spots. For additional information, refer to WSM section 206-00.
Some 2013-2016 Escape/Fusion/MKZ vehicles may display an error message when updating the All Wheel Drive-ATC Barcode using the IDS service function after installing a new rear drive unit assembly (RDU) or active torque coupling (ATC) clutch assembly. To prevent this error from occurring, enter the universal ATC 4 digit barcode 7772. Once programmed, perform several figure 8 turns at parking lot speeds to verify there is no binding from the all wheel drive (AWD) system. If the vehicle binds in a turn, perform Pinpoint Test A. Refer to the Workshop Manual (WSM), Section 308-07A > Diagnosis and Testing.

The failure pattern owners describe
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
