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.
This Service Information bulletin announces availability of a new front brake pad shim kit to specifically address customer concerns of a squeaking or squealing sound on the models listed above.

The failure pattern owners describe
Owners of 2015 Subaru Outbacks describe a variety of brake system malfunctions. The most critical involves complete brake failure—pedal goes to the floor with zero response at traffic lights and low-speed parking situations, forcing drivers to use the parking brake or steer to avoid collision. One owner replaced brake pads and applied aftermarket noise-free compound without stopping pulsing and squeaking during braking; dealership visits yielded no diagnosed problem.
The EyeSight pre-collision braking system has engaged without visible obstruction ahead, triggering hard braking at highway speeds (70 mph down to 25 mph) and creating rear-end collision risk. Dealerships and a Subaru corporate engineer unable to recreate the issue declined to repair it.
Electronic parking brake failures include spontaneous engagement while parked or driving, wheels locking up and immobilizing the car, and failure to disengage. One owner reported this issue reappeared after a previous recall (WTB63) was completed. Some complaints mention sudden unintended acceleration paired with unresponsive brakes, brake pedal positioning that allows foot contact with the accelerator at low speeds, and brake line corrosion severe enough to require replacement. Dealership diagnostics frequently fail to identify root causes in intermittent failures.

Failure modes owners describe
Brake pedal unresponsiveness / complete brake failure
Brake pedal pressed but vehicle does not decelerate or stop. Reported as pedal going to floor with no activation, spongy feel, or requiring extreme force to engage.
When: At parking lot entry (32k mi), traffic light approaches, low-speed situations
Symptoms owners cite: Pedal goes to floor with no brake activation; Brake does not respond to pressure; Requires extreme force to stop vehicle; Spongy pedal feel with excessive travel; Parking brake also unresponsive in one case
Repairs/costs cited: One owner replaced brake pads and added noise-free compound without resolution. Dealership inspections found no issues. One vehicle required tow to dealer.
Brake pulsing and loud squeaking noise
Brakes pulse and emit loud squeaking during braking. Pulsing accompanied by brake tightness and delayed stopping. Reported as ongoing issue from used car purchase through repeated dealership visits.
When: Since initial used purchase (April 2018 through November 2018)
Symptoms owners cite: Loud squeaking noise during braking; Pulsing sensation in brake pedal; Brake tightens up during pulsing; Delayed stopping / does not stop immediately; Noise persists after brake pad replacement and noise-free compound application
Repairs/costs cited: Owner replaced brake pads themselves and applied noise-free compound; neither resolved the issue.
EyeSight pre-collision system unwanted braking
EyeSight automatic braking system engages without visible obstruction ahead. Reported at speeds from 25–70 mph in various conditions (sunny, rainy, highway, residential streets). Braking force can be substantial, creating rear-end collision risk.
When: Multiple occasions over 2+ years and 30k miles; one instance at 65 mph, one at 70 mph with adaptive cruise control, others at lower speeds
Symptoms owners cite: Car brakes suddenly without cause or visible obstruction; EyeSight warning given before braking; Significant hard braking at highway speed (70 mph → 25 mph); System releases control after short deceleration; No cars in front or nearby when braking occurs
Repairs/costs cited: Dealership unable to recreate problem. Subaru corporate engineer inspected vehicle and data recordings but found no issues; stated repairs impossible without recreation.
Recalls/TSBs owners mention: Subaru corporate engineer investigated but could not find fault.
Electronic parking brake malfunction / unintended engagement
Electronic parking brake engages without driver input while parked or driving, or fails to disengage when activated. Wheels can lock up, immobilizing vehicle. Issue reappeared after previous recall repair (EPB Reprogramming WTB63).
When: While parked (12 days, overnight), while driving, at low speeds during parking lot situations
Symptoms owners cite: Parking brake engages without pressing switch; Red warning light blinks while driving; Parking brake will not disengage after repeated starts; Left rear wheel locked in position (others free); All four wheels locked up in one case; EyeSight system shut down in one case
Codes mentioned: C1411, C1194, C1956, C1942
Repairs/costs cited: One repair involved electronic parking brake connector failure. Service advisor recommended not using parking brake for multi-day parking on flat surfaces.
Recalls/TSBs owners mention: Recall WTB63 (EPB Reprogramming) completed, but issue reappeared. Warranty extension repair performed for connector failure case (Code C1411, C1194, C1956, C1942).
Sudden unintended acceleration (SUA) with concurrent brake malfunction
Vehicle accelerates when driver releases accelerator and applies brake. Brake pedal unresponsive simultaneously. Reported at parking lot entry at low speed.
When: 32k miles, parking lot entry, low-speed turning maneuver
Symptoms owners cite: Foot comes off accelerator, vehicle accelerates instead; Brake pedal does not respond to pressure; Vehicle continues accelerating across parking lot barrier; Brake finally engages after prolonged pedal application
Recalls/TSBs owners mention: Vehicle at dealership awaiting evaluation. Owner suspects throttle control computer malfunction.
Brake pedal positioning interference with accelerator
Brake pedal positioned too high or positioned such that right foot can contact accelerator pedal when only partially on brake. Results in unintended acceleration at low speeds (traffic lights, parking).
When: At traffic lights, parking spots, nearly stopped or stopped conditions
Symptoms owners cite: Brake pedal can be depressed below accelerator level; Right foot can depress accelerator while only partially on brake; Car accelerates unintentionally when braking; Occurs at low speeds near stops
Engine surge / acceleration during low-speed braking
Engine revs or vehicle accelerates while braking at very low speeds (parking, traffic light scenarios).
When: Low-speed braking situations (not specified in detail)
Symptoms owners cite: Intermittent engine acceleration or surge while braking; Occurs at very low speeds
Brake line corrosion
Brake lines severely corroded, requiring replacement. Reported at second dealer inspection during trade-in appraisal. Subaru attributed cause to salt damage despite owner's minimal commute use.
When: 86,801 miles
Symptoms owners cite: Severe corrosion of brake lines and sub-frame
Repairs/costs cited: Brake lines and sub-frame required replacement.
Recalls/TSBs owners mention: Manufacturer stated failure was caused by salt damage; owner disputed claim as vehicle used for leisure, not commute.
Sudden deceleration / stall while driving
Vehicle suddenly decelerates from highway speed while cruise control active, losing significant speed and stalling. Occurred in two separate instances over a year apart.
When: 80,700 miles (reported instance); prior instance one year earlier at ~55 mph
Symptoms owners cite: Sudden deceleration from 67 mph to 25–30 mph; Vehicle stalls; Deceleration lasts several seconds; Occurred twice over approximately one year
Repairs/costs cited: Dealership unable to determine cause. Vehicle was not repaired.
Recalls/TSBs owners mention: Manufacturer was made aware but no diagnosis or repair provided.
