My 2014 Subaru Forester was rear ended when it was all of 3 months off the lot. After about $6k in repairs to mainly the bumper and lift gate, plus some “pulling” of the rear quarter panel, it has not achieved the fuel efficiency I had pre-accident. It is rated 24 mpg city and 32 mpg highway (27 mpg combined), and before the accident I was averaging about 28-29 mpg combined and often achieved 32 mpg on highway trips. Now, I’m around 18 mpg city, 27 highway. I took it to Subaru to see if they could figure anything out that was related to the accident and repairs, and they found nothing wrong with it.
Does anyone have any ideas what this might be related to?
