The '22+ with the 2.5T has that idle start/stop. According to 2021 Kia Stinger Features & Options, the 21 2.0T did not have this. Or maybe it did... It's unclear!@# Owner's manual makes reference to it, but says some models.
With the ISG, i expect the 2.5T to have a beefier starter. Hopefully last longer too, esp if you disable ISG.
Dropped off at 9:30am - May 3rd
They gave me a loaner 2023 Kia Sportage.
My car was completed the following day, May 4th, around 4:00pm
In addition to the starter motor, they also replaced 1 headlight assembly ($246.60 labour) and 1 door mirror ($65.80 labour) during that same visit j-. But the massive bulk of the labour was clearly the starter motor remove and replace.
