2008 lexus 460 ls - complaint regarding danger of death due to carbon monoxide. this car is keyless which often results in the failure of their driver shutting off the engine which is at times parked inside an enclosed garage of a home. this occurred on three different occasions at my home. thank god i had a carbon monoxide alarm in my home which alerted me of this problem . lexus should have installed some sort of switch which would automatically shut off the engine when the driver seat has been unoccupied for fifteen minutes. lexus states they have received many complaints throughout the country, however there is nothing they can do about this problem and danger . existing cars should be recalled and repaired and this should be mandatory for all future cars with a keyless system. *tr
