Why is my Kia Niro's hybrid battery not charging properly?

I noticed that my Kia Niro's hybrid battery is not charging as fast as it used to. How can I fix this issue?

First, make sure that you are using a quality charging cable and that it is properly plugged in. You should also check the charging port for any debris or buildup that may be hindering the connection.

If the charging cable and port are fine, the issue may be with the battery itself. The battery may need to be replaced if it is not functioning properly.

Another possible solution is to reset the hybrid system by disconnecting the negative battery terminal for a few minutes and then reconnecting it. This may reset any errors and allow the battery to charge properly again.

If none of these solutions work, it may be time to take your Kia Niro to a dealership or mechanic to have it professionally diagnosed and repaired.
