Service brakes, hydraulic:pedals and linkages
Model years: 2020
Problem: Subaru of America, Inc. (Subaru) is recalling certain 2020 Outback and Legacy vehicles. The brake pedal mounting bracket may have a missing or insufficiently tightened bolt.
Risk: A missing or loose bolt may cause the brake pedal mounting area to deform over time, which can reduce braking performance and increase the risk of a crash.
Fix: Subaru will notify owners, and dealers will inspect the brake pedal mounting bracket hardware and replace the hardware or brake pedal assembly, as necessary, free of charge. The recall began October 1, 2019. Owners may contact Subaru customer service at 1-844-373-6614. Subaru's number for this recall is WUL-97.

Model years: 2017
Problem: Subaru of America, Inc. (Subaru) is recalling certain model year 2017 Outback vehicles manufactured June 20, 2016, to June 23, 2016. The affected vehicles may have improperly tightened attaching bolts for the front left and right brake calipers, wheel hubs, and the right stabilizer clamp.
Risk: If any of the front brake caliper, wheel hub or stabilizer clamp attaching bolts loosen or detach, the related components would also become loose and may detach possibly making the vehicle unstable and reducing the braking capability. These conditions would increase the risk of a crash.
Fix: Subaru has notified owners, and dealers will inspect the bolts for proper torque, and replace any loose bolts, free of charge. The recall began on August 8, 2016. Owners may contact Subaru customer service at 1-800-782-2783. Subaru's number for this recall is WTE-66.

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.
