Subaru recalls 400,000 vehicles due to engine control and valve defects

Subaru is recalling over 400,000 vehicles in the U.S. to repair two separate problems with engine computers and motor debris.

The first recall from the Japanese automaker concerns 466,000 Impreza compact cars from 2017 to 2019, together with the 2018 to 2019 models of the Crosstrek sports utility vehicles. Subaru stated the engine computers in the models can continue to power the ignition coil after motors are shut off. That can result in a short circuit and a blown fuse.

Subaru stated car dealerships will update the software and replace the coils and front exhaust pipes if required.

The second recall concerns 205,000 vehicles in 2017 to 2019 models of Impreza cars, together with the 2018 Crosstrek SUVs. The automaker stated the aluminum positive crankcase ventilation valves can fall apart, potentially causing debris to fall into the engine and result in a power loss. 

Subaru owners can get dealers to replace valves if required. If a valve has separated and parts can’t be discovered, engines will be replaced.

These recalls will start on December 13.
