Last weekend I wanted to see what the ML system sounded like from the rear seats. I got in and started my RX350h in ACC mode just to listen to my sound system. After listening in the drivers set, I got into the rear seat to see how it sounded like back there. I then got out and tried to open the driver door. It would not open. The mirrors were not folded, and my phone app said that it was opened. I tried to lock and unlock from the app but nothing happened. So, I pulled on the manual latch and was able to get in. I then turned off the RX and then tried to start it. It wouldn't start and there was a message on the dash saying to hold the key fob to the start button. The RX started but then I got another message that my brake pressure was low, see dealer. When I took my RX to the dealer, they checked the error codes and said that when I got out of the driver's seat and into the rear seat that denies entry and diables it from starting. The break pressure message was caused by a low voltage from not being able to start my RX. This is all supposed to be a safety feature. Just thought I'd pass this along in case this happens to you.
