Service bulletin WQS-54

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Subaru of America, Inc. (SOA) is recalling certain 2015 model year Subaru Legacy, Subaru Outback, Subaru Impreza (4Door and 5Door) and Subaru XV Crosstrek vehicles and certain 2016MY Subaru WRX vehicles equipped with a Driver Assist System. The programming of the Driver Assist System will not detect a fault in one of the associated system components. In the event of Brake Lamp Switch (BLS) failure, the Vehicle Dynamic Control (VDC) correctly detects the BLS failure, but the Driver Assist System will be delayed in detecting the BLS failure. Therefore, it will take longer for the multi information display to inform the driver of a malfunction. In addition, VDC will not receive the brake request from the Driver Assist System, resulting in no automatic braking, including Adaptive Cruise Control and PreCollision Braking.
