BLUETOOTH® SOUND QUALITY CONCERNS ON
UVO eSERVICES (UVO 3.0)
This Pitstop provides information to diagnose and repair 2017-18MY Sportage (QL) and
2017MY Niro (DE HEV) vehicles, with UVO eServices (UVO 3.0) head units, produced after
June 15, 2017, in which the following Bluetooth® sound quality customer concerns occur:

While driving, on the other end of the call (not the vehicle side), the voice breaks up and
can hear static

A Bluetooth call is intermittently choppy on both ends

Intermittent clipping (words are muted) especially when talking vehicle to vehicle
through Bluetooth

“I am in an area with strong carrier coverage and the call sound quality is fine when I
switch from the vehicle’s Bluetooth system and talk directly from my phone. However, it
cuts out when I talk through Bluetooth”

“My phone works fine in my other vehicle, however, it cuts out in this Kia”
NOTE: This concern can be improved for some customers by encouraging the use of
Apple CarPlay™ since the phone is connected through the cable and Bluetooth is
disconnected when using Apple CarPlay.
This concern can occur when using Android Auto™ since the phone is connected
through Bluetooth.
The cause of this concern is increased noise cancellation applied in both iOS and Android
operating system software by the phone manufacturers that resulted in combined noise
cancellation by the phone and the head unit (worst case condition is when on a call through
Bluetooth to another cell phone connected through Bluetooth).
It is recommended to have the customer update their phone with the latest phone operating
system software and to confirm if the issue is still present.

If a customer complains about this exact concern and it can be duplicated, and the vehicle
meets the above criteria, replace the head unit with a remanufactured head unit to obtain the
updated software, if applicable. Report any reoccurrence of the issue after head unit
replacement by opening a Techline case.
