What stands out
Owners have filed 161 brakes complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
No new NHTSA brakes complaint has been filed on this vehicle in over 5 years — the issue may be aging out of the active population.
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.

The failure pattern owners describe
Owners consistently describe brake pedal sinking to or near the floorboard—sometimes intermittently, sometimes persistently—with severely reduced stopping power and extended braking distance. This happens without warning lights in many cases, though some report check brake system messages, ABS warnings, or a "spongy" pedal feel.
The failures often follow ABS activation (hitting a bump, hydroplaning, or hard braking on slick surfaces), then the brake pedal loses pressure and won't respond normally until the driver pumps it repeatedly or restarts the engine. The problem recurs unpredictably—from days to weeks apart—making the vehicle unsafe for emergency stops.
Dealers and independent shops struggle to diagnose it. Common repair attempts include bleeding brake lines, replacing brake pads/rotors, replacing the master cylinder, and flushing brake fluid—none reliably fix it. Most mechanics eventually point to the ABS hydraulic control unit (HCU) or ABS module as the culprit, citing internal valve corrosion or sticking valves that remain stuck open after an ABS event. Replacement parts are frequently on national backorder. When repairs happen, costs range from $850 to $2,764 for parts and labor. Some owners report premature rear brake wear with pitted and scored rotors at very low mileage (under 27,000 miles), attributed to stuck calipers.

Failure modes owners describe
ABS hydraulic control unit (HCU) valve malfunction
Internal corrosion or mechanical sticking of ABS valves, typically triggered by an ABS event (bump, hydroplane, hard braking on ice/snow), causes the valve to remain open. This bypasses brake pressure, sending the pedal to the floor with little to no braking power.
When: Intermittent, often follows ABS activation; can occur at any mileage from early ownership (~5,700 miles) to 220,000 miles
Symptoms owners cite: Brake pedal sinks to or near floor; Loss of braking power after ABS event; Pedal goes soft/spongy; Extended braking distance; Pedal regains pressure after pumping or engine restart; Unpredictable recurrence; Usually no warning light before failure
Codes mentioned: ABS system fault codes (when detected), Check Brake System message, ABS warning light
Repairs/costs cited: ABS hydraulic control unit replacement; parts frequently on national backorder. Costs cited: $850–$2,764 for part and labor. Some owners report shops manually fabricate test devices because factory diagnosis is difficult.
Recalls/TSBs owners mention: Ford issued recall 19S54 for 2006–2010 model years (Fusion/Lincoln/Mercury) with same ABS valve issue, but 2011 model year excluded despite identical complaints. Parts backorder due to high demand.
Brake master cylinder failure
Master cylinder loses pressure or leaks brake fluid, reducing hydraulic pressure and causing the pedal to sink. Some owners report multiple replacements within months or years.
When: Variable; one owner reported three failures within 6 months
Symptoms owners cite: Brake pedal sinks to floor; Reduced braking power; Hard to stop vehicle; Occasionally brake fluid leaking from the unit
Codes mentioned: Check Brake System message (sometimes)
Repairs/costs cited: Master cylinder replaced, sometimes multiple times. Despite replacement, failure often recurs, suggesting underlying system issue or poor part quality.
Premature rear brake caliper and rotor wear
Rear brake calipers stick or fail to release properly, causing excessive friction, pitting, and scoring of rotors. Occurs at unusually low mileage and age (under 27,000 miles, 3.5–4.5 years old), despite light driving.
When: Early in vehicle life; documented at 23,544 miles (4.5 years old) and 26,600 miles (3.5 years old)
Symptoms owners cite: Rear brake pads worn to 2 mm in short time; Rotors pitted and scored with uneven wear; Rotors gouged several mm deep; Calipers not functioning properly/sticking
Repairs/costs cited: Complete rear brake overhaul (calipers, rotors, pads). Dealers and mechanics cite corrosion causing caliper malfunction.
Brake failure with loss of pedal pressure and no warning
Complete or near-complete loss of braking power with brake pedal depressing fully without resistance, often with no prior warning lights or symptoms. Most dangerous scenario as it occurs with no advance notice.
When: Occurs suddenly without pattern; mileage varies from 5,700 to 220,000 miles
Symptoms owners cite: Brake pedal goes to floor with no resistance; Little to no braking power; Vehicle cannot stop or stops very slowly; No warning lights or messages before failure; Check Brake System or ABS warnings appear after failure begins
Codes mentioned: ABS fault codes, Check Brake System message, Brake warning light
Repairs/costs cited: Diagnosis difficult; multiple shops may be unable to identify cause. When found, usually ABS HCU or master cylinder. Parts backorder common.
Recalls/TSBs owners mention: Ford directs owners to NHTSA. Earlier model years (2006–2010) covered under recall 19S54, but 2011 excluded.
Spongy/soft brake pedal with excessive travel
Brake pedal feels spongy or soft, requiring significantly more travel (press halfway to fully depressed) to achieve normal stopping power. Persistent condition that worsens over time.
When: Develops at varying mileage; one owner noted onset around 100,000 miles, becoming constant by 105,000 miles
Symptoms owners cite: Brake pedal feels soft/spongy; Excessive brake pedal travel required; Need to press brake further down than normal; Intermittent at first, then constant; Stopping power still present but pedal feel abnormal
Repairs/costs cited: Brake fluid bleeding attempted; may be temporary fix. Often points to ABS HCU issue.
Brake vacuum hose/assembly failure (early 2011 model)
Defective vacuum hose or assembly in brake system causes brake warning light and tone, affects hybrid electric mode operation.
When: Documented at 5,700 miles (5 months old)
Symptoms owners cite: Brake warning light and warning tone; Vehicle drops out of hybrid/electric mode; MPG display fluctuates
Repairs/costs cited: Vacuum hose/assembly replacement; part was back-ordered, not available until October 2011.
Recalls/TSBs owners mention: Ford technician hotline identified the part; back order issued.
Single-side ABS activation during braking
ABS engages only on one wheel (usually driver-side) during braking, causing tire wear on that side and unpredictable braking response.
When: Occurs repeatedly over time
Symptoms owners cite: ABS engages on one side only; Uneven tire wear on one side; Unpredictable braking during sudden stops
Repairs/costs cited: Root cause not identified in complaints; relates to ABS system malfunction.
Unintended acceleration concurrent with brake failure
Vehicle experiences unintended high-speed acceleration while in reverse; brake pedal fails to stop the vehicle immediately, resulting in crash.
When: Documented once at 90,000 miles
Symptoms owners cite: Sudden unintended acceleration in reverse; Brake pedal depressed but vehicle does not stop immediately; Vehicle crashes into parked vehicle then residence; Airbags did not deploy
Repairs/costs cited: Not repaired; vehicle taken to body shop. Owner suffered facial and neck injuries.
Recalls/TSBs owners mention: Dealer visits twice before crash found no cause; Ford opened a case and directed owner to NHTSA.
Right-front brake caliper freezing
Caliper locks in compressed position, preventing brake release after hitting a bump. Occurs twice on same vehicle within 1,000 miles.
When: First incident at 116,000 miles after front-end rebuild; second at 117,000 miles after hitting bump
Symptoms owners cite: Right-front brake compresses and locks; Brake does not release; Vehicle immobilized after hitting bump
Repairs/costs cited: First incident: caliper replaced, rotor turned, pads replaced. Second incident: HCU/PCM replacement recommended (not performed in complaint).
Recalls/TSBs owners mention: Dealer identified as common problem in Fusions; suspected defective pin in HCU/PCM.

I was driving my 2011 Ford fusion hybrid at around thirty MPH on a city street and my brake system warning light popped up on the dashboard. As soon as that happen I had no brakes, and there was no resistance in the brakes. They went straight to the floor, luckily I was able to stop the car with my emergency brake. I restarted the car and the brakes worked fine after that.
After starting the vehicle and putting the car in reverse with the brakes engaged, the vehicle kept reversing even with the brakes completely depressed. The brakes engaged after a couple of seconds and after that they worked normal. This issue has happened 3 more times since this first incident and the pattern has always been the same. *js
The ABS control unit failed and almost made me crash in the highway on n 680 exit treat blvd ,and I spent $1500 just to find a solution. This is a recall that needs to be addressed.
