Why does my Elantra Hybrid jerk or hesitate when I pull away from a stop?

Short answer: Many Elantra Hybrid owners feel a delay and then a jolt when pulling away slowly. It's largely how the dual-clutch transmission and hybrid system hand off at low speed, but a clunk or frequent hard jolts deserve a dealer check. Make sure recall 23V589000's software is done on 2021-2023 cars. If the car loses power climbing hot hills, ask the dealer to check motor and battery temperatures, because it can happen with no codes.

Symptom: From a stop or near-stop, you press the gas and nothing happens for a moment, then the car surges with a jolt, sometimes with a clunk. Some cars also slow to about 30 mph on long hot uphill highway stretches.

What to check first

1. Run your VIN at nhtsa.gov/recalls for 23V589000 (motor control software).
2. Ask whether a newer transmission or hybrid software update is available.
3. Note exactly when it happens: from a full stop, rolling, with Auto Hold on or off.
4. For hot-hill power loss, ask the dealer to read motor and hybrid battery temperatures during a drive.
5. Record it with a dash cam so the dealer can see it.
6. Keep repair records.

Likely causes

1. Dual-clutch transmission and hybrid hand-off at low speed. The Elantra Hybrid uses a dual-clutch transmission, an automatic that shifts like a manual with two clutches. Owners say low-speed starts can feel like a missed clutch while the hybrid system decides how to drive the car.
2. Motor control software. Recall 23V589000 updates motor control software on 2021-2023 Elantra Hybrids because it may cause unintended acceleration after you release the brake.
3. Auto Hold or stop-start transition. One owner suspected the car getting ready to Auto Hold. Another turned that off and still had the jerk.
4. Electric motor overheating on long hot climbs. A 2023 owner's car slowed to about 30 mph on hot interstate hills with the hybrid battery at 5%, and a mechanic measured the motor at over 260°F with no codes.

What it usually costs

Owners didn't post prices. Recall work is free, and the hybrid system is under Hyundai's hybrid warranty on most of these cars.

Is it safe to keep driving?

The low-speed jerk is unsettling but usually brief. Leave extra room in stop-and-go traffic. Power loss on a hill with trucks behind you is dangerous. Use the right lane and hazard lights, and get it checked before long summer trips.

DIY or shop?

Not much to DIY. Transmission and hybrid software and diagnosis are dealer jobs.

Quick tip

Some low-speed roughness is normal for this car, but a clunk, frequent hard jolts or power loss aren't. Get the recall done and push for a recorded test drive.
