If you tacked the optional subwoofer onto your 2015 Subaru WRX, or the person who originally ordered it did, you should probably take it to a dealer. Subaru is recalling 9,178 Subaru WRX sedans for a potential fire hazard caused by faulty subwoofer wiring.
If you’re one of the 9K affected, your local Subie service department will look over your subwoofer and subwoofer wiring harness and install a wire retaining clip to help keep the wires from rubbing against the subwoofer box’s metal frame, which can produce a short. If the wiring, subwoofer or subwoofer amplifier is damaged, Subaru will replace parts as necessary — free of charge.
There are no current reports of this hurting anyone, but there’s always a risk of harm with a fire hazard. Subaru reportedly received the first complaint about this problem earlier this year, with subsequent complaints rolling in shortly after.
