Ioniq Power Window Failure After Battery Replacement
Summary of the thread
After replacing the battery in a 2020 Ioniq electric vehicle, the power windows stopped functioning due to an error related to unsuccessful window regulator initialization. A hard reset by disconnecting the 12V battery did not resolve the issue. The solution involved taking the car to a workshop where the window regulators were reinitialized using specialized software, successfully restoring window operation.

Yes, I disconnected the 12V battery for about 30 minutes, but the problem remains. Is this the same issue you had with your car?

Yep, exact same symptoms. Unfortunately, a reset didn't fix it for me either. In the end I took it to a workshop to get the window motor reinitialized. They told me that they needed special software for that.

Thanks for the confirmation. I took the car to the workshop as suggested. They reinitialized the window regulators and the windows are working again. Repair cost was 290€.

I have a similar Ioniq. I had a power window issue after some electrical work. Did you try a hard reset? Disconnecting the 12V for a bit?
