I have a 2019 Forte S and have encountered a similar problem, to no avail to any actual formal acknowledgment or insight, as well. Coming from a 2009 Vw Jetta with the Audi A4 Independant suspension, I can simply add my own feedback and insight into the KIA’s single rear axle suspension being very unforgiving on bumps, and this might be a factor in the front suspension noise, as less road impact vibration is absorbed, and its distribution is not as localized on my newer vehicles’ more primitive and less premium suspension design.
