Symptom: A pause before the car moves from a stop, a stutter or shudder at low speed, rolling back on hills, or in the worst cases, no movement when you press the gas.
Likely causes
- Software. Recall 16V628 and campaign T1B updated the transmission and engine software. Hyundai Forums owners say T1B helped more than the first fix, though some hesitation remained.
- Clutch judder. Hyundai's 2021 bulletin adds a judder test and transmission software update, and replaces the clutch only if the judder continues.
- Driving style. Creeping in stop-and-go traffic overheats the dry clutch.
Cost
Recall and campaign work is free. Clutch replacement out of warranty varies, so get a quote.
