My Crosstrek AC was going off and on. Took it to our local mechanic. Apparently the electrical windings related to the air conditioning compressor are part of a defective assembly. Cost to repair estimated at $1,600. Subaru posted an internal bulletin acknowledging the problem and recommending replacement of the unit. Contacted Subaru Customer Advocacy Dept and now I need to take it to a Subaru dealer for another diagnostic. I am hoping Subaru does right and straightens this out for we consumers.
