Coming back from Key West a few weeks ago, my car started to vibrate a lot when i would step on the gas at about 35-40 mph. All the lights came on and a "decreased power" warning came on. It kept happening periodically, I took it to the dealer and they told me one of the fuel injectors went bad. Apparently it's a common issue for the IS. Took a day to fix, GOOD AS NEW. good luck
