Subaru Recalls More Than 466,200 Cars in U.S.

Subaru Corp. is launching two recalls in the U.S. to fix faulty electronic engine controllers and emission controls in hundreds of thousands of cars and crossover vehicles.

The broader campaign targets engine controllers in 466,200 of the company’s 2017-2019 Impreza sedans and 2018-2019 Crosstrek SUVs.

The National Highway Traffic Safety Administration says the modules may leave the engine’s ignition coil switched on too long after the engine shuts off, thereby causing the coil to overheat. Overheating could trigger a short-circuit that blows a fuse, which would switch off the engine or prevent it from starting.

A second recall involves 205,300 of the same Subaru models to replace a device that could disintegrate, dump debris into the engine and damage components inside.

The recall applies to Impreza and Crosstrek vehicles whose engines are fitted with an improperly made aluminum positive crankcase ventilation valve. If the PCV value comes apart, bits could enter the engine. Dealers will remove the debris or, if necessary, replace the engine itself.

The tandem campaigns are expected to begin in mid-December, according to NHTSA.
