I own a 2025 Hyundai Elantra Hybrid and I’m trying to find out if anyone else has experienced similar behavior.

The issue occurs mainly at low speeds (0–10 mph), especially in stop-and-go traffic or after coming to a near stop.

What I experience:

• After braking to a stop or near-stop, I lightly press the accelerator
• There is a noticeable delay before the car responds
• When power engages, the vehicle suddenly surges forward rather than accelerating smoothly
• The transition is abrupt and feels like a driveline shock or sudden engagement
• At the moment it happens, there is a strong impact-like sensation, similar to a light rear-end collision
• In some cases, I can also hear a noticeable thud or mechanical “clunk” coming from underneath the vehicle area (around the floor/seat region)

When it happens:

• After braking and then re-accelerating from low speed
• In heavy stop-and-go traffic
• Occasionally during EV mode or hybrid power transitions

Additional notes:

• The behavior is repeatable under similar conditions
• I can consistently reproduce it
• The vehicle has already been at the dealership twice
  • First visit: 4 days, issue not resolved
  • Second visit: currently ongoing (~9 days in service)

Question:

Has anyone else experienced similar low-speed hesitation followed by a sudden jerk or impact-like engagement in this model?
