What owners report

  • Battery fails repeatedly, sometimes multiple times within the ownership period, even after dealer replacement.
  • Vehicle randomly dies or bogs down while driving, with warning lights appearing across the dash.
  • Windshield or rear windshield cracks or develops a hole on its own with no impact, in one case at 5,200 miles.
  • Vehicle fails to start, later traced by an independent mechanic to a telematics control module needing replacement.
  • Rear seatbelt webbing frays without warning, and the dealership declines to treat it as a warranty issue.
  • Brakes fail to stop the vehicle in an emergency situation, leading to a crash where airbags did not deploy and the seat belt failed to lock.

    Exterior lighting:back up lights:switch

    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.
