Service brakes, hydraulicReported December 31, 2014 · 200,064 vehicles affected
What is wrong
Subaru of America, Inc. (Subaru) is recalling certain model year 2008-2011 Impreza, 2008-2014 WRX and STI, and 2009-2013 Forester vehicles, currently, or formerly, registered in Connecticut, Delaware, Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, West Virginia, Wisconsin and the District of Columbia that were remedied under recall 14V‑311 prior to December 23, 2014. The brake lines may experience brake line corrosion due to salt water splashing on the brake lines through a gap in the fuel tank protector.
Risk
Brake fluid may leak due to the brake line corrosion and may result in longer distances being required to slow or stop the vehicle, increasing the risk of a crash.
Remedy
Subaru will notify owners, and dealers will apply an anti-corrosion wax to the four-way joint connector area of the brake line system, free of charge. The recall began on January 27, 2015. Owners may contact Subaru customer service at 1‑800‑782‑2783. Subaru's number for this recall is WQQ-52. Notes: This recall is specific to affected Forester, Impreza, WRX, and STI customers who had their car remedied under the federal safety agency recall no. 14V‑311 prior to December 23, 2014. Subaru has determined that this remedy was inadequate due to incomplete repair instructions provided to dealers. Affected Forester, Impreza, WRX, and STI vehicles that were not repaired under the federal safety agency recall no. 14V‑311 prior to December 23, 2014 will continue to be processed under the federal safety agency recall no. 14V‑311. Affected vehicles not currently, or formerly, registered in the salt belt states identified in this recall are eligible for repair, at no cost to the customer, upon request.

The firewall welds that support the brake master cylinder and the clutch master cylinder are making a popping sound when I release the clutch pedal. I found online that this is a known issued with the 2008-2014 model year subaru wrx. I also read that the firewall can completely break from repetitive clutch and brake pedal use and if it would break I would have no clutch or brake pedal to use and could become a safety issue. This issue happens when at a stop or moving as long as you hit the clutch pedal it pops. This issue has happened since I purchased the vehicle in january of this year. I am reporting this issue with hope that the fix becomes a recall considering how dangerous it can be if the firewall does break.
