Non-Turbo with CVT Models only. Subaru of America, Inc. (Subaru) is initiating a Service Campaign for certain 2017 model year Forester normally aspirated vehicles with CVT transmissions. Subaru has determined vehicles affected by this Service Program require additional CVT fluid.
The CVT fluid (CVTFII) in affected vehicles was not filled to the proper specified level at the factory.
The condition could cause a noticeable air vacuum noise or possibly even chain slip under high levels
of shock load depending upon driving conditions (i.e. rapid acceleration or hill climbing). Extended
driving under this low-fill condition is not recommended.
