Subaru of America, Inc. has issued two separate safety recalls for different problems affecting various models. 

ECM Software Issue

The automaker is recalling about 466,205 2017-2019 Subaru Impreza and 2018-2019 Crosstrek vehicles for a malfunction connected with the Engine Control Module (ECM). Specifically, the ECM may continue to power the ignition coil after the engine is shut off, causing a short circuit.

This is a concern as a short circuit in the ignition coils may cause the engine to stall, increasing the likelihood of a collision. 

To remedy the matter, Subaru will notify owners, and dealers will update the ECM software, replace the ignition coils and, if necessary, the front exhaust pipe, at no cost to owners. 

The recall begins May 28, 2021. Subaru's number for this recall is WRE-21. Subaru notes that this recall includes all vehicles previously repaired under Recall 19V743.

Rear Stabilizer Problem 

In a second action, the automaker is recalling an estimated 408,271 2018-2019 Subaru Crosstrek, 2019 Crosstrek Hybrid, and 2019 Forester vehicles because the rear stabilizer bracket bolts may loosen and detach.

In the event of missing bolts, there is the possibility that the rear stabilizer bracket can shift which increases the risk of a crash. 

To fix the problem, Subaru will notify owners, and dealers will retorque and replace any missing bolts, free of charge. The recall begins May 14, 2021. Subaru's number for this recall is WRD-21.
