The 2013 Subaru Impreza has 3 recalls, the most serious being a fire risk on turbocharged models where a faulty relay causes the secondary air injection pump to run continuously, overheat, and melt.
On the engine side, valve springs can fracture and cause the engine to stall unexpectedly, raising the risk of a crash. There is also a brake light switch concern where the brake lights may not illuminate when the pedal is pressed, leaving drivers behind without warning that the vehicle is slowing or stopping.
