It has gotten cold in Northwest Florida and have noticed something strange when starting my 2000 Rx 300 in the morning after sitting for 24 hours. Right after startup the steering wheel does not turn like it should; if I can describe the issue in words (try to turn to steering wheel and it reacts forcefully against me; almost feels like the belt or something is slipping when backing and turning, it also feels like low engine RPMs just before a stall, but RPMs are fine. Does not do it all the time, only after sitting for a while. Any clue?
