Welcome to the forum @ZeeSpurs. What does your trip computer say your mileage is?I am having same issue. LX model 2022 bought in Canada. I had 16 Touring Civic and gas was good on it. I really wanted to get into an electric but Honda has been doing nothing in terms of options so I went for a new Civic thinking it would save me gas and money. I drive around 120 KM roundtrip 3-4 days a week and I am having to fill up once or twice a week. I actually believe my wife's Audi Q5 has better gas mileage than this thing. It is costing me around $50 to fill up the tank at around 1.36/L. I am at around 5,000KM and I thought it would 'break in' by now. This is absolutely ridicilous to be honest for a company to go backwards on gas mileage in this day and age.
As a side note, is anyone experiencing crappy bluetooth connection and loss during Apple Car Play?
