Has anyone experienced this? First they were all going off when the speedometer was jumping. I noticed then the hybrid system only warning was on and the speedometer was steady. Now, 2 days later all warnings are off and it’s back to normal? Any ideas?

If lucky you only need a new 12 volt battery because the cold weather makes if harder for your old 12 volt battery. Lower voltage causes all kinds of random warning lights because the systems need the proper amount of power to work.
The recent extreme cold has caused a lot of marginal batteries to fail. It happens every winter.
Get your 12 volt battery checked. Any of the big auto parts chains like Auto Zone or Advance Auto do this for free and will install a new battery too!
If you know it is the original battery or over 5 years old, just replace it and I bet that will solve your problem.

Thank you! I hope so too. I did change the 12v battery less than a year ago with an interstate battery bought at Costco. Anything is possible and I will bring it to get checked. I did stop by my local Lexus dealer and showed the service manager the video and he said it seems like a voltage issue too.
Any advice of something else it could be would be appreciated. Thank you.
I second having your battery checked.. I haven't had this issue with my rx but had a car with all those electronics takes alot of power! I was like noway is this the only thing wrong, but I was wrong, new battery everything resolved just like that!
