I've got a 2013 Avenger SXT. Few things that I've learned about it since I've owned it, the gas when I fill it up and if I run it to e I will have only driven 200-220 miles. What do y'all get from a full tank? 3.6 obviously. Another thing is the transmission shifting so aggressive , it annoys me have been told it's how they all are and that I got it checked out and nothing. What are some other flaws about y'all cars so maybe I can compare ?
