I've been seeing people talk about this issue happening to them across this forum as well as other Lexus forums and I have come across this article. It may become a recall to be fixed.

Some Lexus vehicles in the USA are experiencing a navigation system error, causing a reboot loop that makes it impossible to access the vehicle’s infotainment features. The cause of the issue appears to be a faulty over-the-air software update

Moe Durand, a spokesman for the Lexus luxury division, said the problem may have been caused by a faulty application in the kind of software the automaker routinely ships to customers’ vehicles via satellite. Durand said the company hasn’t determined yet whether vehicles will have to return to dealerships to fix the app.
The automaker is getting calls asking, among other things, whether it’s been a victim of a cyberattack or had engaged in some kind of promotional stunt, he said. The issue can also affect radios, which are displayed on the same dashboard screen, Durand said.

This just happened to me this morning when I started the car. Going to call the dealership to see what they say.

Terribly sorry to hear that. But definitely as it is now a known issue. Hopefully they'll put out a TSB or a full recall soon. Let us know what the dealership response is please !

Hello
I had the same issue but it is resolved now. I called my dealership and they said to unplug the battery for 20-30 mins and plug it back in. That worked for me and the issue is resolved.

Dealership has no solution at this time. Really disappointed that this has been going on since Monday and there is no solution. I was advised that unplugging the battery was just a temporary fix.

Per Lexus.com, the errant data from the weather and traffic application caused this problem. The data has been removed and the system needs to be reset. To reset the system, the negative battery cable needs to be removed for 10 minutes. This will remove the errant data from your system and it should load correctly at the next start-up. You may have to reset all of your settings after this process though.

Just disconnected the negative cable of the battery for 10 minutes and started the engine. The system did a reboot and now everything is working! Thanks!

You're welcome! Did you have to reset all of your personal settings (did they go back to factory defaults)?
