Service bulletins for the 2006 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.

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

WVU31R2018-04-02. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE; ENGINE AND ENGINE COOLING. 2.5 Liter N/A engine only. REVISED. Subaru of America, Inc. has determined that vehicles affected by this Service Program require ECM reprogramming. A modification to the Engine Control Module software logic has been developed to improve the performance of the emission control system. This software change will not adversely affect fuel economy or performance. This software update is intended to improve vehicle emissions when the vehicle is operated in cold weather and the engine is turned off and restarted within short periods of time such as in several minute intervals. The A/F sensor contains a heating element, which is controlled by the ECM, and which assists the sensor in reaching an optimum temperature, resulting in better accuracy. When the vehicle is operated under the conditions described above, there could be a longer than desired delay in the ECM?s turning on the A/F sensor heating element, resulting in higher than desired emissions. This software enhancement will correct that condition.
WVM23R2018-04-02. Service bulletin. ENGINE AND ENGINE COOLING. REVISED. CA PZEV SPEC MODELS ONLY. Subaru of America, Inc. (SOA) has determined that vehicles affected by this Service Program require ECM reprogramming. Under certain severe driving patterns, such as high speed highway/uphill driving and/or accelerating with high engine revolutions, the efficiency of an affected vehicle?s catalytic converter may begin to degrade beyond design parameters. (The ?Check Engine? light will illuminate to alert the driver if the catalytic converter efficiency has degraded beyond an acceptable level and if the vehicle may be releasing air pollutants that exceed Federal or California emission standards.) To prevent this condition, a modification to the Engine Control Module software logic has been developed that will improve management of the catalytic converter. 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."
