Any help is appreciated. I've searched the forums but nervous that I may have to go to the dealer!

I have a 2017 RR LWB Supercharged. Car has been great. Other than normal maintenance and wear and tear, no issues.

Today got in the car and driver seat wouldn't move into memory position. Dash showed an error that rear passenger door was open. It was not. Checked multiple times. Driver seat controls don't work, doors won't lock (from key fob or any of the interior door lock switches), dash also shows a child security fault. Driver rear passenger power seat controls don't work, but both passenger side power seats work.
Drivers massage seat also does not work. Car won't lock either. Try to lock with key fob, and get the 2 beeps since it thinks the rear right door is open.

I haven't seen anything with all these issues together. I checked all fuses, no issues there, but the really strange part is my ID tool shows no faults. I can see how the door actuator on the rear passenger could be part of the problem, but with all the other seat issues, and only on the drivers side is really strange.

Any ideas or help would be appreciated.

thanks. tailgate works fine. i'll try disconnecting the battery. will keep you posted thanks for the input.

Has damp got in somewhere? I see your in Texas but it does rain there right

tried disconnecting the battery. While we have had rain, it was in the parking garage at the airport all week while it rained and it was sunny dry when it just stopped working. Think I may try to find a used door latch/actuator and replace it. will keep everyone posted. thanks!

Well replaced the door latch hoping that would solve it but it didn't. I'm just stumped as to why the Gap diagnostics tool isn't seeing any code.

I trying to do everything to not go to the dealer, but I may have to. Once fixed I'll update.

See "ghosts in the machine" thread below, maybe problem with earth point in wheel arch, which seems to cause multiple electrical faults? Only Range Rovers since 1988

I'd check the charge state of the battery - you mention that it has been sat for a week in an airport carpark all week - the alarm may have been going off or some other drain on the battery.

There are many post about random dash errors or things just not working because of not enough charge in the battery.

I'd try giving it a good charge or at least checking the voltage before throwing too many new parts at the problem. Ash

Check the ground connections under the front wheel liners. 2017 SDV8 4.4 silicon silver AB

Well finally got everything sorted. The ground under the front driver's seat broke. They had to disassemble most of the interior because the driver seat didn't move. Appearently multiple control units used that ground. It took so long because their one mechanic who could do aluminum welding was out for an extended time. Not a big deal ultimately. They did a ton of trouble shooting and to trace it back to that was impressive. Most places would have given up or replaced a bunch I f components.

Thanks for the help!
