With any Toyota hybrid or Lexis it is impossible to run just the gasoline engine if there's a problem with the hybrid transaxle.

It the car runs on the gas engine...why can't it just stay in that "mode?" Seem simple to me..why is it not?
Expert:  Skyvisions replied 3 months ago.

It may seem like a simple thing but the logic that controls the system is very complex. It will not run on just the gas engine due to the way the system is designed. It is designed to regenerate the battery when slowing down or braking and if there is an issue with the battery that's causing it to kick out and you wanted to run just on engine it won't do that. There's no way to override it with the software.

You are welcome. I can't argue your logic they are definitely more complex and not made as simple as it used to be. If you have not done so please do not forget to apply a rating of three or higher so I may be compensated for my time.
