I have driven various Lexus's including other 350's as a " loaner" when I took mine in for service, but have noticed no similar problems. My wife was out of commission for for over a year with surgeries, and when she started driving it again, she also complained about the aggressive jerk when pressing the accelerator. It can be controlled but does require attention each time. When a quick start is required, you are going to feel an uncomfortable jerk and very noticeable jerk.
