Service bulletins for the 2015 Subaru Outback

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.

WQS-542018-06-11. Service bulletin. VEHICLE SPEED CONTROL:CRUISE CONTROL; LANE DEPARTURE: LANE KEEP: STEERING ASSIST; FORWARD COLLISION AVOIDANCE: DYNAMIC BRAKE SUPPORT/BRAKE ASSIST; ELECTRICAL SYSTEM. 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.
15-182-15R2018-06-11. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE; EQUIPMENT:ELECTRICAL:NAVIGATIONAL SYSTEM(GLOBAL POSITIONING SYSTEM). This bulletin announces a procedure for updating the navigation / audio unit?s operating system software. The following list of symptoms and related changes provides a brief description of which customer concerns the updates are intended to address.

WTB-63B22018-06-11. Service bulletin. ELECTRICAL SYSTEM; PARKING BRAKE. New Service Program: WTB-63 Electronic Parking Brake (EPB). ReprogrammingThe EPB system is designed such that the parking brake will apply upon initial activation and re-apply approximately 150 seconds (2 ½ minutes) after initial activation. Due to improper software programing of the EPB system, if an affected vehicle?s ignition switch is turned to the ?ON? position at the same time the parking brake is re-applying, electric current will be provided continuously to the left rear EPB motor, eventually causing the motor to seize and prevent release of the parking brake. Should the left EPB motor seize, it will be necessary to replace the EPB Motor Gear Unit- EPB LH.

WTB-63B2018-06-11. Service bulletin. ELECTRICAL SYSTEM; PARKING BRAKE. TSB. The EPB system is designed such that the parking brake will apply upon initial activation and re-apply approximately 150 seconds (2 ½ minutes) after initial activation. Due to improper software programing of the EPB system, if an affected vehicle?s ignition switch is turned to the ?ON? position at the same time the parking brake is re-applying, electric current will be provided continuously to the left rear EPB motor, eventually causing the motor to seize and prevent release of the parking brake. Should the left EPB motor seize, it will be necessary to replace the EPB Motor Gear Unit- EPB LH.

11-145-14R2018-06-11. Service bulletin. ENGINE; ELECTRICAL SYSTEM; EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL. Revised TSB. This bulletin announces the availability of reprogramming files and a revised oil level switch to optimize the ECM logic for engine oil level detection in the event of false or premature low engine oil level warning lamp illumination. Should a customer present a concern with a low engine oil warning lamp illumination and the diagnosis indicate the oil level is full or nearly full (oil level between the full and add marks/holes on the dipstick) and the customer has not added any engine oil, the ECM must be updated with this new logic and the oil level switch specified below replaced. The new oil level switch part number supplied in this bulletin must be used. If the customer has added oil, determine how much was added. Based upon the information provided, estimate where the oil level was when the lamp illuminated in order to determine if additional action is required beyond what is described in this bulletin (e.g an oil consumption test). The ECM must still be updated with this new logic and the oil level switch replaced.
01-168-09R2018-06-11. Service bulletin. EQUIPMENT ADAPTIVE/MOBILITY; EQUIPMENT; EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL. Revised TSB.
