Known issues on the 2013 WRX. Owners filed 7 complaints on the 2013 WRX, 6 of them about the power train and 2 about service brakes, and 1 complaint reported a crash. The year carries 11 recalls. A brake light switch campaign reaches certain 2013 WRX sedans, where contaminants can stop the switch working, so the brake lights fail to warn following traffic, keyless-ignition cars may not start and automatic cars may stay in park. Certain 2013 WRX vehicles sold or registered in listed states were also recalled over passenger frontal air bag inflators that can burst on deployment after long exposure to moisture and temperature swings. Procedures, specifications, wiring diagrams and diagnostics cover the transmission, brakes and air bag system.
