I have a lexus 300 es hybrid that advertises 39/40 mpg. i have been getting in the upper 28-31 mpg for 2 and a half years now .when i first received the vehicle in the first month i complained about this gas mileage problem. they told me the vehicle needed to break in for 500 miles. after that i contacted lexus again, they said the car needed a 2000 mile break in . i keep getting more and more excuses and the run around. then they told me it was my driving habit. i have a class a commercial drivers license and have been driving big rigs for over 15 years . i now how to drive and i have a very good driving record with no incidents to date. so that excuse was another pass-the-buck routine from lexus. i let this go for such a long time, since i was discouraged and very disappointed in the horrible customer service and accountability from lexus. this was just too much to understand. i had a lexus 200 ct pre paid lease that gave me very good mpg. i wanted a larger vehicle so after seeing the maroney 39/40 mpg boasted on the lexus 300 es hybrid and on many national advertisements, i decided to turn my ct 200 in six months early at a $2000 pre payment loss to me. this decision was solely based on the proclaimed advertisement claims under federal law and testing updates that i solely relied on . i now feel that i was exploited to lease my 300 es hybrid under false advertisment claims and fruadulent claims by lexus.why do i say that? because the vehicle has never given me anything close to the mileage claimed , never have i had 35 + miles on this vehicle and most of the time always exclusively in the 29-31 mpg range. this is not a problem i caused. this is a problem lexus caused. i have been cheated and deceived and ignored, told there is nothing they can do . i had the car checked and they gave me a song an d dance story. since they need the car for a while to check this.
