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

  1. 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.
  2. Clutch judder. Hyundai's 2021 bulletin adds a judder test and transmission software update, and replaces the clutch only if the judder continues.
  3. 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.

  3. In traffic, leave a gap ahead and pull away smoothly instead of creeping.

Safety / mechanic note
