Subaru recalls certain 2017 Imprezas to recode engine control software

Subaru is recalling certain 2017 Impreza models to fix a software issue that may lead to stalled engines. When using a winter fuel blend required in some North America regions, which vaporizes at a lower temperature, the fuel may begin to vaporize in the fuel line under high ambient temperature, low speed or stopped driving conditions. The software program in the engine control unit is not set to a low enough temperature when using winter blend fuels. Dealerships will reprogram the engine control unit to turn the radiator cooling fan on at a lower temperature, free of charge.

Key Takeaways:

  • Premature vaporization can lead to rough idling, the inability to start the engine or a stalled engine.
  • The company also issued a stop-sale order for new, unsold Imprezas that are affected by the recall.
  • The recall covers 33, 131 Impreza sedans and hatchbacks in the U.S. built between Sept. 13, 2016, and March 15, 2017
