I just purchased a 2004 RX330 with 6000 miles on it. Love the car so far. However, I just filled the gas tank up for the first time and was only able to put 15.6 gallons in the tank. The range left on the car was 8 miles and the warning light was on, so I assume that I had pretty much emptied out the tank. After I filled the tank, the range was listed as 300 miles, consistent with a 15 gallon tank. The capacity is listed in the manual as being 19.2 gallons. This seems like a fuel gauge or other electronics issue. I am going to call my dealer tomorrow. Has anyone else had this problem and if so, what has been the response of Lexus?
