Hello Scotty,
I recently took my 2013 Ford Focus SeHb to Firestone and they replaced 3 motor mounts, pads and 2 roaters, fid an alignment. Afterwards the car runs smooth but the gas mileage has dropped a good amount, what could be the issue and should i take it back and demand they fix it free of cost? The gas mileage was still very good beforehand even though it had a rough idle, thank you Tim.
Check the receipt to find out what services they have done. With the repairs you mentioned, the mpg should be intact.
I will do that when i get home, the situation makes no sense to me either, thank you for the reply and advice
Maybe they accidentally disconnected a sensor somewhere? Any codes? (Not all OBD2 codes trigger the check engine light.)
They probably accidentally bumped an electrical connector or partially loosened a vacuum line somewhere. Take it back and have them do an engine compartment inspection. It's probably minor.
