Consumer Description

Brought vehicle in for Recall-SC340 Theta II 2.4L GDI ECM S/W Upgrade. After service was performed I took my vehicle back home and noticed that my down shifting was different, jolty and clunky. Prior to the upgrade my vehicle shifted flawlessly. Took my vehicle back in to have them check it out and they told me that they couldn't feel it and that the upgrade wouldn't cause that. Called Kia Corporate and filed a complaint.
