## NHTSA's summary

NON\-TURBO MODELS \- Subaru of America, Inc. \(Subaru\) has determined that certain 2017 model year Forester normally aspirated vehicles equipped with CVT transmissions will 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 \(i.e. rapid acceleration or hill climbing\).
