Allion Transport Mode Active Error

I'm stumped. I've got a 2023 Toyota Allion, hybrid engine, with 171873 km on the clock. Randomly, the system is displaying 'Transport Mode Active' and throwing a bunch of errors. The navigation is completely dead, and there seems like a general electrical malfunction. It's like the car's brain just went on vacation. I checked the key fob battery, fuses, but no luck. Could this be some weird car configuration issue? I even tried to reset things through the dashboard, but no dice. Any ideas before I'm forced to surrender to the dealership's diagnostic check?

Whoa, 'Transport Mode' randomly activating? Sounds like my Allion’s midlife crisis a while back. I was going crazy with similar symptoms – navigation dead, electrical gremlins popping up everywhere. Feels like your car is stuck in the Matrix! Did you try any specific sequence with the key fob? It almost sounds like the car forgot its identity. There is a chance this could be related to a software glitch. Did you have the chance to perform a diagnostic check?

Interesting! Key fob sequence, you say? I did try replacing the battery, but didn't attempt any special dance moves with it. What kind of sequence are we talking about? And did you solve it by doing that?

Well, not exactly 'solved', but the symptoms disappeared. Sorry, I was too happy. Anyway, the key fob sequence didn't fix anything but it’s worth a shot just in case. I eventually had to accept my fate. It seems that the problem is deeper than that. The issue might reside in the immobilizer or the ECU. The best thing you can do is to take it to the workshop.

Got it. Sounds like a workshop visit is inevitable. Thanks a bunch! I was hoping to avoid it, but I've learned my lesson. Car is still under warranty, so I dropped it off this morning; they said it was a software issue that needed a reset. All is good and the repair cost was 0€!
