Hesitation when accelerating on other Santa Fe years
No other Santa Fe model year has enough reports of hesitation when accelerating for a sheet of its own. See every Santa Fe year.
What this problem usually is
This is the narrower sheet inside transmission shudder for a car that pauses before it goes. You press the gas, and for a beat nothing happens, or the engine revs and then the car catches up. What makes it distinct from the wider sheet is timing: the complaint isn't a rough shift at speed but a delay right when you need to move.
What got replaced
Owners who name the part that was replaced mention the transmission (14 reports) and the software (13 reports).
