I just had the same problem with my 2008 GS350. The brakes worked intermittently, shifter would not release and/or not smoothly, ABS warning on, and car wouldn't start with smart switch. I noticed that the brake petal would sometimes be extremely firm, but other times would go almost to the floor. Pumping the brakes several time seemed to unlock the shifter and allow driving. Problem identified as the stop switch.
