From what I've read, it's a real issue that dates back at least as far as '04.
The real problem in my mind is not that the throttle sticks, but that the brakes cannot overcome the engine. Their ~280 hp V6 cars have the same measly brakes as the ~180 hp 4-cylinder cars. That's just not smart.
Another issue is the throttle/brake override. After the Audi 5000 debacle, most (all?) German cars kill the throttle when the brakes are engaged. I'm not sure if it's once a certain threshold is reached or just any brake contact, but that could really hamper left-foot braking (not that 99.99% of car owners would care).
Anyway, I hope this makes Toyota and Lexus used values drop for a little while. I want another IS300.
