New 2010 Legacy that the A/C fails to cool the car. The A/C is set to max cool, fan fast. After setting in the sun for a few hours, the inside temp is 120 degrees, the output from the vent at best is about 60 degrees. After running for 40 minutes it brought the cabin temp down to about 90 degrees. The cabin filter is new, the freon/coolant is correct with no leaks per dealer. We even went to another vehicle on the lot and tested it with same thermometer and it did do a little better but not much. Dealer tells me that they changed the A/C this year to an on demand compressor with a sensor that determines cabin temp unlike old compressors with a clutch. Has anyone else noticed the lack of cooling in their Legacy or have any suggestions. I opened a complaint with Subaru but they don’t seem to be too concerned. It is a black car with tan leather interior. Subaru did update that the car is working as designed. I plan to go to another dealer for a second opinion but feel their answer will follow the company line.
