Glad to have found this group and hope someone can help. Car was bought new in summer of 2014. It was fantastic for the first 4 years — 50-55 MPG and sometimes more on highways, mid-30s suburban/city in cold weather and 40s in warm.
About 10 months ago, the MPG fell through the floor. We now get on average 10 MPG less than before.
No changes — same drivers, same gas stations, same roads. Car has been dealer serviced from the start and they can’t find anything. Thanks in advance and HELP!!!
