The dominant complaint pattern for the 2015 Subaru WRX centers on the powertrain and engine. On the powertrain side, owners report issues with drive axles, differential seals, and drive belt failures, often discovered during dealer inspections prompted by unusual noises. The engine complaints are the more serious thread, owners frequently describe a loud knocking or ticking sound that develops while driving, with several reports pointing to connecting rod bearing failure requiring short block or full engine replacement. This pattern shows up across a range of mileages, with some failures occurring before 60,000 miles. Exterior lighting rounds out the top three complaint categories, though at much lower volume. The connecting rod bearing failures are the most consistently described symptom, with owners reporting sudden loss of power and audible knocking as the typical warning signs before the engine is pulled for inspection.

By System
The 2015 Subaru WRX has 3 recalls, the most serious involving the optional factory-installed trunk subwoofer, where cargo shifting in the trunk can pinch the wiring against the metal frame, causing a short that can overheat the amplifier and start a fire.
On the engine side, a cracked turbocharger air intake duct can cause the engine to stall unexpectedly, leaving the driver without power in traffic. The third recall covers the backup light switch, which can corrode and stop working, leaving the reverse lights dark and the rearview camera image blank when the car is in reverse, reducing what the driver can see behind the vehicle.
