My brand new Es300H shows different milauge capacity each time I fill the tank. When I purchased it brand new it showed the driving range of 675 miles with full tank. Since then it has been continuously dropping by 20 to 30 miles each time I fill it up. Now I will be lucky if I can get even 500 miles range. I showed it to two different dealers in dallas, Texas area. They both claim that the car is adjusting to my driving style (that indirectly means I am a bad driver). It has been 3.5 months since I purchased it and it is still dropping. Can driving style make that big a difference (nearly 200 miles less than the original range indicated)? I don't think so and I believe that dealers themselves do not know what is going on with my engine/ hybrid system. But they refuse to do anything about this problem.
