I am not sure if this is a standard fear but it is not in mine. I have the base SR5. This is minor but it has bothered me that there is no bell/tone alarm when the ignition key is in or headlights are kept on. It does not remind you of leaving the key in the ignition or walking away with the light s on. They do not automatically turn off. There have been times where I could have easily locked my keys in the car or left the lights on. The reminders for both of these is absent.
