 I am extremely disappointed by the way Hyundai USA decided to handle my handsfree case.  This issue was present since day 1 of us purchasing the vehicle in 2017.  I spent a lot of my time at home and away from work troubleshooting and sending several audio recordings to the company and have been able to re-produce the issue with every single phone call, however the dealership kept the vehicle for several hours and returned it back stating "we don't see a problem".  I purchased a new phone, and switched 3 different carries, however the problem never went away.  I am extremely saddened by Hyundai's lack of ownership of the issue.  The least Hyundai could do is try to replace the radio or the microphone to eliminate the issue, instead Hyundai decided to close the case.  However, after this experience, I will be taking my business to a company that stands behind their customers.  It is such a shame for the entire Hyundai team that they won't stand behind the customer and fix something that is still under warranty.  Overall, the car has a lot of bells and whistles, but what good are they if they don't work.
