Elantra central locking failure
Summary of the thread
A 2023 Hyundai Elantra Hybrid experienced a central locking failure, with none of the doors locking or unlocking and an error code being displayed. The issue was not related to the fuses or the car alarm system. A possible cause was identified as a faulty cable connection in the fuse box. The problem was resolved by a workshop, confirming the defective cable connection as the source of the issue.

The car alarm seems okay, so I don't think it's the security system. You mentioned a faulty connection in the fuse box - was it visibly damaged, or did you have to test each connection?

Nah, couldn't see any damage. I tried wiggling a few wires but didn't want to mess with it too much. Honestly, I'd recommend taking it to a workshop. They can properly diagnose the issue and avoid causing further problems. It sounds like it might be the same defective cable or plug connection I had.

Thanks for the advice! I took it to the workshop, and you were right – it was a defective cable connection. Cost me 95€ to get it fixed. Appreciate the help!

I had a similar issue with my Elantra, although it wasn't the hybrid version. Does your car alarm still work? If not, it could be related to the security system or a faulty connection in the fuse box. Have you noticed any other electrical issues?
