The Subaru Impreza and Crosstrek have been hit with two separate recalls in the United States.

The first recall relates to 2018-2019 Crosstrek and 2017-2019 Impreza models. According to the National Highway Traffic Safety Administration (NHTSA), the engine control module used by the cars may continue to power the ignition coil even after the driver shuts the vehicle off. This could lead to a short circuit and a blown fuse.

Were the car to suffer a short circuit while being driven, it could suddenly lose power, increasing the risk of a crash, and may not immediately restart.

To resolve the issue, dealerships for the Japanese car manufacturer will update the engine control module software. A technician will also inspect the ignition coil to see if a replacement is needed. Vehicles that require a new ignition coil will also be equipped with a new front exhaust pipe. This recall affects a total of 466,025 Crosstrek and Impreza models.

As for the second recall, it impacts a total of 205,000 Crosstrek and Impreza models from the 2018 and 2017-2018 model years respectively. In this case, the positive crankcase ventilation (PCV) valve could separate, allowing engine oil into the combustion chamber. Pieces of the damaged PCV valve could also enter the engine and cause vehicles to lose power.

Affected owners will need to take their Crosstrek and Impreza models to a dealer where a technician will inspect the PCV valve and replace it. Tests will then be conducted to see if the new part also separates. If it does, the separator cover and oil pan will be removed and Subaru will replace the short block engine.
