My RX400H mileage was pretty good for the first three months, but over the past week, in town mileage dropped from 28-29 MPG to 22-25MPG. Motorway (freeway) driving performance seemed to climb from 30-31 MPG to 31-32 MPG.
Have sent the car back to be checked out - I live in London and do a lot of in town driving. Will report back - has anyone else experienced the same drop in MPG?
