After complaining twice since purchasing my Niro EX in September/October 2018. I finally got them to find the source and fix it. Front lower control arms worn and cracked. Replaced under warranty even though I do have the 120K extended warranty. I see polyurethane inserts in my future, if it wears early again. So if your Niro creaks like an old stagecoach as weight shifts or suspension loads and unloads. This could be your culprit too.
