I must have a lemon or something wrong with my 2011 Aveo5. Has 65k miles on it. All tuned up, plugs, tires, filters, tranny flush, all done by GM tech. My fuel economy is 22city 27 highway. I live in Florida. All flat roads. I get between 230/250 miles on a tank of gas. Unbelievable low for such a tiny car. No check engine lights. Car some days runs rough, sometimes bogs down, feels gutless. Then most days is all fine no issues. GM tech says car is fine, nothing is wrong. Recall replacing plugs and boots were done according to GM records by my Vin number. Idk what else to do. This car is a gas guzzler for no reason.
