Can you ensure the car is in park?Move lever to D and then back into Park and see what happens.I have heard with this particular model, we have the environmentally unfriendly RX 330, that the batteries lack of charge may play havock with the electrics in these cars.I religously charge my battery every six months with a smart charger so its always in peak, I also find a quick zap at the first cold snap of autumn / winter gives us trouble free motoring.
