The 2013 Subaru Impreza has 3 recalls, the most serious being a fire risk on turbocharged models where a faulty relay can cause the secondary air injection pump to run continuously, overheat, and melt.
On turbocharged models, that same overheating pump can reach temperatures high enough to ignite nearby components, so this recall is worth checking first if your car has a turbo engine. The second concern involves the engine's valve springs, which can fracture and cause the engine to malfunction or stall without warning while driving, leaving the vehicle suddenly unpowered in traffic. Finally, the brake light switch can fail to illuminate the brake lights when the pedal is pressed, meaning drivers behind you may not see that you are slowing or stopping in time to react.
