2020 Range Rover Sport HSE, while at a light car goes to park and shuts off.

The fuel saver is turned on, check the owners on how to deactivate it.

You are talking about the gas saver/engine shutdown at a stop light. That is not the behavior, i know how to turn that off. This will NOT put the vehicle into PARK and then shut down all the controls. I have it on all the time and know the distinct difference between that and what is happening.

You didn’t mention the loss of controls in the first post, this indicates something is going on with the computers shutting everything down, better have the dealership check it out and don’t let them tell you they can’t verify it. There should be a memory of the vehicles failures in the computer, if not then for sure there is a major electronic problem.

Thanks - taking it in already.

Good luck with the dealership
