Subaru is recalling 2018-19 Crosstreks due to a problem with the engine, which doesn’t shut off after it is shut off.

Subaru of America is recalling more than 450,000 late-model Imprezas and Crosstreks in two separate actions.

The recalls cover as many as 466,205 vehicles, according to Subaru in a statement to the National Highway Traffic and Safety Administration.

The first recall covers 2017-2019 Imprezas and 2018-2019 Crosstreks for an engine problem. After the engine is shut off, power may still flow, and could results in a short circuit of blown fuse, the company noted.

This can increase the risk of a crash if the short circuit happens while the car is in use. There have been no crashes, injuries or deaths related to the issue, according to NHTSA

The second action includes 2017-2019 Imprezas, but only the 2018 Crosstrek. On these vehicles the Positive Crankcase Ventilation valves that may come apart and cause debris to fall into the engine. This can result in loss of power while the vehicle is in operation, increasing the possibility of an accident.

Both recalls are expected to start Dec 13, and the automaker plans to notify owners if their vehicle needs to be inspected. There are no reported incidents of a crash occurring due to these problems. Subaru issued the recall under an abundance of caution.

Subaru had a major issue earlier this year where it recalled 2,000 vehicles, replacing them entirely.

The automaker has advised the National Highway Traffic Safety Administration that it will recall more than 2,000 brand-new Legacy and Outback models due to manufacturing defects so potentially severe that it is offering to buy back or replace, rather than repair them — though the vehicles will later be repaired, a spokesman told TheDetroitBureau.com.

There’ve been a handful of cases where manufacturers have bought back vehicles because of problems that cannot be repaired. Volkswagen did so following its admission it had rigged the diesel engines on a variety of models. But it is rare for a manufacturer to then replace the vehicles with new ones.

The announcement by Subaru covers 2,107 Legacy and Outback models from the 2019 model year. According to the automaker, there are faulty welds below the cowl panel that could fail over time. If that were to happen, it could result in a crash and, making matters worse, reduce the effectiveness of body structures designed to reduce injuries to vehicle occupants.
