The repair is fairly simple.

Subaru will recall 4,216 examples of the 2017 Impreza in the Canada and 33,131 in the United States for an issue with how the vehicles deal with the winter mix of fuel in North America.

The winter fuel blend vapourizes at a lower temperature than other mixes, but the engine control unit’s software doesn’t handle this properly. The radiator fan might not activate at a low enough temperature, which can cause the gasoline to vapourize. This decreases fuel pressure, which leads to a rough idle or a stall. If the problem causes the engine to stop running, it might be difficult to restart, too.

2017 Subaru Impreza


Subaru only reports one instance of this problem happening to a driver. A complaint on January 3, 2017, noted that an Impreza stalled, and a further analysis by the company discovered this fault. There are no known injuries from this issue.

Dealers will install updated ECU software that will fix the problem, which will take about half an hour. Subaru doesn’t yet report when the repair campaign begins. There’s also a stop-sale in effect for units of the 2017 Impreza with build dates between September 13, 2016, and March 15, 2017, in showrooms until the sellers remedy this issue.
