NHTSA's VIN data lists these trims for the 2015 WRX. A trim's engine and numbers are shown as its own only where EPA names versions after the trim and no other version could be it; "seen with" means a source shows that engine on the trim, not that it was the only one. Recalls and complaints cover the whole model year: whether a recall applies to a car depends on its VIN, on NHTSA's recall lookup.
Owners have filed 55 complaints with NHTSA about the 2015 WRX. These are unverified owner reports, counted by the part of the car they name; one complaint can name several parts. Counts aren't adjusted for how many were sold, so they don't show how reliable a car is.

Complaints by model year
Newer years have had less time to collect complaints, and counts aren't adjusted for sales, so a shorter bar doesn't mean a more reliable year.
NHTSA lists 3 recall campaigns for the 2015 WRX over its history. Campaigns are matched by model and year, so each one may apply to a given car, and its repair may already be done: check a VIN on NHTSA's recall lookup for the open recalls on that exact car.
Subaru of America, Inc. (Subaru) is recalling certain 2015-2021 WRX vehicles. The backup light switch may corrode and become inoperative, which can result in the backup lights not illuminating and the rearview camera image not displaying when the vehicle is in reverse.
Risk: Inoperative backup lights and an inoperative rearview camera can reduce vehicle visibility and driver awareness, increasing the risk of a crash.
Remedy: Dealers will inspect and replace the backup light switch, as necessary, free of charge. Owner notification letters were mailed September 16, 2022. Owners may contact Subaru's customer service at 1-844-373-6614. Subaru's number for this recall is WRE-22.
Subaru of America, Inc. (Subaru) is recalling certain 2015 WRX and WRX/STI vehicles, equipped with an optional factory-installed subwoofer in the trunk. Items in the trunk may cause the subwoofer wiring to contact the subwoofer metal frame, possibly resulting in an electrical short.
Risk: An electrical short may damage the subwoofer amplifier, and may result in the subwoofer overheating, increasing the risk of a fire.
Remedy: Subaru will notify owners, and dealers will inspect the subwoofer wire, install a wire retainer clip, and, as necessary, replace the subwoofer, free of charge. The recall began October 31, 2017. Owners may contact Subaru customer service at 1-800-782-2783. Subaru's number for this recall is WTQ-76.

Risk: An engine stall increases the risk of a crash.
Remedy: Subaru will notify owners, and dealers will inspect the turbocharger air intake duct, and replace it as necessary, free of charge, depending on the lot number found on the duct. The recall began April 2016. Owners may contact Subaru customer service at 1-800-782-2783. Subaru's number for this recall is WTA-62.
