 I purchased a 2009 highlander Ltd Hybrid with the expectation that I would experience MPG at or above the sticker stated 27 city and 25 highway.  It seems that there is a problem with the electric motors or the computer which controls the timing of the electric and gas motor operation.  Toyota specifications indicate that the three electric motors come on line in higher torque needs such as when starting from a light or going up grades to minimize the use of the gas engine. This car does not do that.  The gas engine is forced to run in almost all situations because only the front electric motors operate.  The car acts like a standard gas vehicle instead of a hybrid.
