Hello everyone: A firmware update was done about the time a recall was completed addressing the rusting brake distribution valve issue ! After the firmware was updated my fuel mileage dropped from 24mpg to 19mpg. I complained to my dealer who basically shrugged it off. I told the dealer I wanted to address the issue with Suburu's dealer support representative but I never hear back from anyone! Have others had a similar firmware result?
