Parts/Service

The release of the 2014 XV Crosstrek Hybrid brings with it a great deal of new
technology and innovation. Chief among these are Start/ Stop and EV Mode
drive operations. These modes of driving are new to our customers and as a
result will undoubtedly prompt some questions on the Service Drive.
In order for technicians and SOA to better understand these inquiries and
customer comments, FHI has created a Hybrid specific Interview / Diagnostic
Check Sheet. This three page form combines a customer interview form that
the Service Advisor can use to gather the full details of any customer concern, a
diagnostic check sheet for the Technician to use to document their findings, and
an appendix of reference information for the Technician to refer to during this
diagnosis. This useful tool is found on Subarunet under Service >> Forms.
We highly encourage and strongly request the completion of this form anytime a
customer presents with a concern related to Hybrid System operation. Subaru
Service Managers and Directors are requested to review this area with all Service
Advisors and Technicians and implement appropriate processes to ensure its
completion anytime a Hybrid owner presents with a concern or question
regarding Hybrid drive functions.
