Has anyone experienced a sudden loss of electrical power? On a recent road trip my 2007 LS460L momentarily(twice) lost all power and then blinked back on. It could be felt in the power assist steering and the NAV screen reset to the first screen. There was a flash of other warning lights and then everything reset.

 

check your connections at your battery. loose terminals can cause that.

 

never happened on my car. was your car moving or when it's stopped?!

 

this happened to me with my IS300. it was acompanied with a audible beep. i never figured out what it was, but it never happened again

 

It's happened 3 times. I was moving and it restarted itself. Will check battery connections tomorrow.
