In regards to MPG, I think our onboard trip computer system that calculates MPG may be off. Since the day I purchased my GT back in May 2018, I have logged every fill-up into an app and each time, the average MPG under 'Accumulated Info' on our dashboard is about 2 MPG higher than what I manually calculated. I usually drive in ECO mode. For example, this morning I filled up and I calculated my MPG to be 20.98 for the past 250 miles driven, the average MPG under 'Accumulated Info' shows 22.7. I would say every time, the trip computer shows an estimate that is 2 MPG higher than actual.
