I was wondering if anyone has had any issues with poor fuel economy. I have had my 2015 GLA 4matic for a few months. I work 114 miles from where I live and make the drive 9 times a month roughly. My fuel economy hasn't been that great. Mercedes says there is nothing wrong but it has gotten worse. My drive is mostly flat. Last time all Hwy I got 25 there and back 27 mpg. I drive it in economy at that is 99 and 88 percent.
