What stands out
Of the 9 model years of Subaru Legacy we track for brakes problems, this one carries the most owner complaints on file — 25.
All 2 active brakes recalls on this vehicle land at critical or severe — none classified moderate.
Brake line corrosion may result in brake fluid leakage. Fluid leakage may result in longer distances being required to slow or stop the vehicle, increasing the risk of a crash.
Fix: Subaru will notify owners, and dealers will test the brake system by depressing the brake pedal and inspecting for brake fluid leaks. If no brake fluid seepage is observed, the affected areas will be rustproofed with anti-corrosion wax. If brake fluid seepage is observed, the brake lines will be replaced followed by rustproofing with anti-corrosion wax. These services will be performed free of charge. The recall began July 2014 and second notifications will run through November 2014. Owners may contact Subaru at 1-800-782-2783. Subaru's recall campaign number is WQK-47. Note: This recall supersedes recall 13V-110 which applied to certain 2005-2009 Legacy/Outback vehicles. Vehicles that were remedied under the previous campaign still need additional areas rust-proofed.

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 Bulletin06-90-24Jun 2024
This bulletin provides diagnosis and procedure information to be applied when diagnosing potential fluid leaks on front and rear brake calipers. This information has been developed to reduce unnecessary brake caliper replacement.
This Service Information bulletin announces instruction for application of additional lubrication between the brake caliper support and pad clips. This will prevent the pad from dragging due to corrosion buildup which may result in uneven or premature wear of the replacement brake pads. This additional instruction applies to all models with brake pads using the upper and lower pad clips and has been added to the brake pad installation procedures found in the related Service Manuals.

The failure pattern owners describe
Brake line corrosion is the dominant issue across these 23 complaints, with rear lines above the fuel tank or near the rear passenger wheel rusting through and leaking fluid. Owners describe the brake pedal sinking to the floorboard while driving—at 25 to 60 mph—forcing them to rely on parking brakes or downshifting to stop safely. The problem typically emerges between 88,000 and 229,000 miles, often three to seven years after Subaru applied anti-corrosion wax coating under recalls 13V110000, 04V274000, 14V311000, or WQK47-2. Multiple owners report the wax treatment failed to prevent renewed corrosion; some had the coating reapplied in later years (e.g., 2019) only to see lines rust again within months.
Dealerships and Subaru have refused repeat repairs under warranty, citing geographic registration restrictions, prior service completion, or mileage thresholds. One owner faced a $3,997 repair estimate for line replacement after the recall treatment proved ineffective. One dealership disputed recall-completion status with NHTSA despite official records showing the repair was done, leaving the owner stranded with inoperable rear brakes. A smaller subset mentions early rotor warping and excessive pad wear at 14,000–26,000 miles, and one ABS failure at 34,000 miles, but the brake line corrosion dominates complaint volume and severity.

Failure modes owners describe
Rear brake line corrosion and perforation
Brake lines, primarily in the rear above the fuel tank and near the rear passenger wheel, corrode and perforate, causing brake fluid leaks. Occurs in vehicles treated with anti-corrosion coating under previous recalls, suggesting the treatment is ineffective long-term.
When: Between 88,948 and 229,126 miles; often 3–7 years after initial corrosion-treatment recall service
Symptoms owners cite: Brake fluid leaking visibly from underbody or rear wheel area; Low brake fluid level in reservoir; Brake pedal sinking to floorboard under braking; Loss of brake pressure or stopping power; Brake warning light illuminated
Repairs/costs cited: Owners cite full brake line replacement as the required repair; one estimate was $3,997.17. Dealerships treated under prior recalls (#13V110000, #04V274000, #14V311000, WQK47-2) applied anti-corrosion wax coating only; rust recurred shortly after in some cases.
Recalls/TSBs owners mention: NHTSA recalls issued: #13V110000 (2013), #04V274000 (pre-2013), #14V311000 (2014), WQK47-2. Treatment was anti-corrosion wax spray on brake lines. Multiple owners report Subaru and dealerships refused warranty assistance for recurrent corrosion after recall service, citing geographic registration issues, mileage, or prior service completion. One dealership disputed recall-completion status despite NHTSA records showing completed.
Front rotor warping and excessive wear
Front brake rotors warp prematurely and brake pads wear excessively, causing vibration and loss of braking power. Owner suspects ABS malfunction; dealership attributed it to normal wear.
When: First occurrence at 14,000 miles; recurrence at 26,000 miles
Symptoms owners cite: Sudden, significant loss of braking power; Major vibrations during braking; Difficulty slowing vehicle
Repairs/costs cited: Dealer resurfaced rotors at first occurrence; replaced front rotors and brake pads at second occurrence. Owner notes the problem is repetitive despite repairs.
ABS (anti-lock brake system) failure
ABS fails during low-speed driving. One owner notes the system cannot be disconnected at the owner's request per dealership policy.
When: At 34,000 miles
Symptoms owners cite: Antilock brakes fail while driving at 25 mph
Repairs/costs cited: Owner requested system disconnection; dealership declined to perform this work.

Hydraulic brake failure while driving. Upon brake application, pedal went to floor, had to use parking brake to stop vehicle. Inadequate, ineffective preventive recall done to brake lines as a rust proofing measure was done twice and lines still rusted through and perforated in rear near fuel tank.

Tl* the contact owns a 2005 Subaru legacy. While operating the vehicle, the brake sensor suddenly illuminated. Moments later, the bakes failed and the brake pedal extended to the floor. The vehicle was towed to the dealer where it was diagnosed that the brake lines positioned above the fuel tank were corroded and caused the brake fluid to leak out. The contact was informed by the dealer that the…

The vehicles brake lines have corroded and started to leak, resulting in the stopping distance increasing and the vehicle not being safe to drive. When getting the airbag recall performed at the Subaru dealership 3 years ago I mentioned the brake line recall. They stated they inspected the lines, and no issue was present. There is now an obvious issue with the brake line corroding and failing.…
