Reliability Issues with 2018+ Lexus LS Models - Anyone Else Experiencing Them?

I'm experiencing recurring issues with my 2019 Lexus LS, including intermittent stalling and complete loss of engine power. Others on this forum have reported similar problems. Has anyone else had reliability concerns with their 2018+ model? Are there any known solutions or updates addressing these issues? I'd love to hear from others who may be experiencing the same problems.
