Lack of Fuel Pressure Causes Stalling in the 2017 Impreza

Are winterized fuels to blame for the stalling engines in 2017 Imprezas? If you ask Subaru, that’s what they’ll tell you.

According to the automaker, while the car is stopped or moving slowly the winterized fuel begins to vaporize in the lines under higher ambient temperatures. When vapor builds up, the fuel pressure goes down which leads to rough idling, stalling, or even a problem starting the engine.

More than 33,000 Imprezas will be recalled but Subaru doesn’t know when.

It’s been a rough couple weeks for the 2017 Impreza which was also recently recalled for memory issues causing blank or frozen rearview camera screens.
