I am leasing a 2004 Lexus RX 330 fwd with about 20,000 miles on it. When I try to apply the throttle after slowing down there is a severe hesitation, usually followed by a sudden surge in power. At times there is an additional hesitation while the transmission is deciding what gear it should be in. This is especially noticeable while making a turn at an intersection, and especially dangerous if there are pedestrians in the intersection. I have had it to the leasing dealer (longo Lexus) and they reprogrammed the transmission, which provided a temporary and partial fix. After a few weeks, aparently the transmission reprogrammed itself and the problem returned. I took the car to a second dealer and he said that they had many similar complaints about that driveline, but there was no factory fix. I called Lexus customer service and they said the same. This problem began shortly after I got the car in April 2003 and still exists. If Lexus truly wanted to fix this problem, it would have already been done. They need a push.
