Sienna Hybrid Transport Mode Issue

Interesting. I have a Sienna Hybrid, too, and I ran into something similar a while back. Transport mode usually means the car's immobilizer and some other systems are locked down for shipping. Are you sure it wasn't accidentally activated? Maybe a software glitch? Does the key fob work properly?

I appreciate the information. The key fob appears to be working correctly for locking and unlocking. However, I am unfamiliar with how transport mode could be activated or deactivated. Could a software refresh be a potential solution?

Yeah, that sounds like what happened to me. The dealer had to reset something with their diagnostic tools; probably a car configuration issue. It's likely a software thing related to the immobilizer, so a software refresh could help, but honestly, you'll probably need them to take a look and clear the transport mode. It's a pain, I know!

Thank you for the clarification and advice. I contacted the dealer, and they confirmed the vehicle was inadvertently left in transport mode during preparation. They reset the system, and everything is now functioning correctly. Repair cost: 0€
