Subaru recalls certain 2017 Imprezas to recode engine control software

on Apr19

The company issued a stop-sale order for new, unsold Imprezas that are affected by the recall.

Subaru is recalling certain 2017 Impreza models to fix a software issue that may lead to stalled engines.

The recall covers 33, 131 Impreza sedans and hatchbacks in the U.S. built between Sept. 13, 2016, and March 15, 2017, according to documents posted on the National Highway Traffic Safety Administration’s recall database.

The company also issued a stop-sale order for new, unsold Imprezas that are affected by the recall. 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 documents said.

Premature vaporization can lead to rough idling, the inability to start the engine or a stalled engine.

The software program in the engine control unit, which operates the radiator fan, is not set to a low enough temperature when using winter blend fuels, the documents said.

To correct the issue, dealerships will reprogram the engine control unit to turn the radiator cooling fan on at a lower temperature, free of charge.

Subaru will begin notifying owners this month.

Last month, the company recalled 25,567 Imprezas for a software problem within the car’s infotainment unit.
