Hello! I am a new 2012 CT200h owner, I bought it used - with 138k kms on it (I am from Ontario Canada). In 3 weeks of ownership, the car has chugged gas like its no one's business! I dont get more than 400 kms (248 miles) on a full tank. I drive in "eco range" and avoid going into the "power" mode. I am not sure what i am doing wrong? there are no lights on the dash. the tires are new, wheels are balanced and alignment has been checked. I called a local mechanic and asked him to "test" my battery and he said unless there is a light he would not do that as it needs a 2-day stay or something weird like that?? i don't wanna take it to the dealership and get robbed to know something basic like "new sparks or XYZ needed"... anyways please give some feedback? what could it be?
