Service bulletins for the 2005 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.

253 on file from NHTSA, as of 2026-10-19.

WVH18R2018-04-02. Service bulletin. ELECTRICAL SYSTEM; ENGINE AND ENGINE COOLING. PZEV MODELS ONLY. REVISED. This Campaign only applies to vehicles with motor vehicle registration in the States of California, Massachusetts, Maine, New York and Vermont. For affected vehicles registered in any other state, see Service Program WVI-19. INTRODUCTION Subaru of America, Inc. (SOA) has determined that vehicles affected by this Service Program require ECM reprogramming along with catalytic converter efficiency testing and possible replacement. Under certain unique driving patterns, such as repeated acceleration and deceleration and/or continuous uphill driving at higher speeds (about 75 mph), the catalytic converters of affected vehicles may develop high internal temperatures that exceed design parameters. If left uncorrected, this condition may eventually degrade the efficiency of the catalytic converters. (The ?CHECK ENGINE? light will illuminate to alert the driver if catalytic converter efficiency has degraded beyond an acceptable level and the vehicle may be releasing air pollutants which may exceed California standards.) To prevent this condition, a modification to the Engine Control Module software logic has been developed that will improve management of temperatures within the catalytic converters. This condition is a software issue and has no impact on vehicle drivability.

If left uncorrected, this condition may eventually degrade the catalytic converters. (The ?CHECK ENGINE? light will illuminate to alert the driver if catalytic converter degradation has already occurred and that the vehicle may be releasing air pollutants which exceed Federal emission standards.). To prevent this condition, a modification to the Engine Control Module software logic has been developed that will improve management of temperatures within the catalytic converters. This condition is a software issue and has no impact on vehicle drivability.
02-164-162017-08-14. Service bulletin. ENGINE AND ENGINE COOLING. This Service Information bulletin announces a design change to the internal contact portion of the oil pressure switch to increase durability
02-162-152017-02-27. Service bulletin. ENGINE. "THIS SERVICE INFORMATION BULLETIN ANNOUNCES A DESIGN CHANGE TO THE OIL PRESSURE SWITCH ASSEMBLY. NICKEL PLATING HAS BEEN APPLIED TO THE INTERNAL SWITCH CONTACTS TO ENHANCE THEIR DURABILITY AND REDUCE THE POSSIBILITY OF POOR CONTACT WHICH COULD AFFECT OPERATION OR CAUSE IMPROPER ILLUMINATION OF THE OIL PRESSURE WARNING LAMP. A SMALL PILOT PORTION WAS ADDED TO THE THREADED AREA ON P.N. 25240KA051 AS SHOWN IN THE ILLUSTRATION BELOW."
