Hyundai Tucson Hybrid jerking problems

Filed Nov 6, 2026 · Brakes, Driver assistance · WI

On approximately three to four occasions, my 2025 Hyundai Tucson Hybrid has suddenly jerked or decelerated while driving, creating the sensation that the brakes were being applied unexpectedly. During there episodes, the vehicle did not respond normally to acceleration until the apparent braking released. A particularly dangerous incident occurred on XXX, when I was entering traffic after leaving a Subaru dealership in [XXX]. The vehicle unexpectedly jerked and failed to accelerate normally while applying the gas pedal. Another driver had to brake to avoid a collision with my vehicle. Hyundai Recall 302 addressing potential unexpected activation of the forward collision avoidance braking system, had already been completed on my vehicle on June 30, 2026. I reported these recurring incidents to the Zimbrick Hyundai service manager on XXX. The braking concern has not been diagnosed or repaired. I do not know whether these incidents are related to Recall 302 or another malfunction. However, I am concerned about unexpected braking or deceleration occurring in traffic and the risk of a serious collision. Attached are documentation confirming completion of Recall 302 on June 30, 2026 and email correspondence with Zimbrick Hyundai service manager documenting my report of the recurring braking incidents dated XXX.

The contact owns a 2025 Hyundai Tucson. The contact stated that while driving at an undisclosed speed, the vehicle unintendedly stopped. The vehicle suddenly experienced an automatic emergency braking failure. The vehicle was stuck in gear and was jerking while moving forward. While in drive, there was an abnormal popping sound coming from the vehicle. The battery discharge message was displayed and after several minutes the vehicle resumed normal operation. The vehicle was taken to the local dealer previously, but the dealer was unable to determine the cause of the failure. The local dealer was contacted again, and the contact was informed about the federal safety agency Campaign Number: 26V316000 (Forward Collision Avoidance) and about a trade-in. The vehicle was not diagnosed or repaired. The contact called another local dealer Feldman Hyundai of New Hudson Service & Parts Center (30492 Lyon Center Dr, New Hudson, MI 48165); where an appointment was scheduled for a later date. The manufacturer was contacted and filed a claim. The failure mileage was approximately 100.

The issue involves the vehicle’s drivetrain and hybrid/electronic control system, where the car suddenly jerked forward in stop-and-go traffic on the freeway as if it had been struck from behind. Immediately following this event, the vehicle would not accelerate beyond approximately 40 mph, indicating a loss of normal power. This created a significant safety risk, as the sudden jerking could have led to a rear-end collision, and the inability to accelerate properly made it difficult to keep up with traffic on the freeway. I was barely able to safely pull off the freeway while surrounding traffic continued at higher speeds, increasing the risk to myself and other drivers. The problem appeared to resolve after turning the vehicle off and then back on; however, this raises concern about intermittent failure. The vehicle was taken to a dealership for inspection, but they were unable to reproduce or identify the issue. The vehicle remains available for inspection upon request. The vehicle has been inspected by a dealer but not by the manufacturer, police, or insurance representatives. Prior to the failure, there were no warning lights, messages, or noticeable symptoms indicating an issue. Based on similar reported experiences, this event may be consistent with a “limp mode” condition or a malfunction in the transition between the electric motor and gasoline engine, potentially involving the transmission or hybrid control system.

While driving, my entire dashboard lit up with every warning sound and symbol for the car. It would cycle through collision, airbags, braking, all of it. Luckily I was able to drive to a safe place. I let the car sit overnight and the alarms stopped. Took it to service and they could not recreate it and no codes showed up. Second time it happened, the warning sounds and lights didn’t stop. The car would jerk when I tried to put it in drive, so I had it towed to dealership. They have video and photos of it. After 2 weeks, they said it was fixed-a pin in a connector was bent. Had car for 3 days and it happened again. Had it towed again. They have had their ‘senior’ techs looking at it, and none can figure it out. There are Reddit posts with this same issue, as well as Hyundai group sites.

There are several electrical issues occurring that have put me in danger when driving. First the screen both on the windshield and the speedometer screen randomly go out completely and I have no idea how fast I am going or any other important features like how much gas my vehicle has, if the vehicle is over heating. The forward/ break feature has gone off multiple times and the vehicle has stopped in the middle of traffic and the freeway with zero warning and with several car lengths between me and the car in front of me. Almost hit from behind when this happens and has put the vehicle in park on the freeway. Steering wheel has jerked to the side when driving making the vehicle almost hit curbs and other vehicles. Has come back to my vehicle that is off and locked and the ac has been running causing the engine to be hot. All the warning lights have turned on and won't go off even after stopping and restarting the vehicle. The vehicle is currently at the dealership with them having to answer to the problem, stating hyundai is aware of the issues but does not know how to fix it. I bought the car in April 2025 and there is just under 2800 miles on the vehicle.

On June 3, 2025, I experienced a terrifying and dangerous incident while driving my 2023 Hyundai Tucson Hybrid on a three-lane road at approximately 50 mph. Without any warning, the gas pedal became completely unresponsive, and the car abruptly decelerated from 50 to 20 mph. This sudden loss of acceleration was incredibly frightening, especially with vehicles close behind me that nearly collided with mine. There were no warning lights or check engine alerts. Fortunately, I was able to safely cross all lanes and pull over before having the vehicle towed to a local Hyundai dealership. I shudder to think what might have happened if this had occurred on a highway at higher speeds. This is not the first time I’ve experienced serious issues with this vehicle. In February 2024, at about 17,000 miles, I received an urgent alert recommending a system check. At that time, the car was revving while idle and would occasionally lurch at low speeds. The dealership had difficulty diagnosing and resolving the issue, and my vehicle remained in the shop for over a month before they ultimately replaced the oxygen sensor. Since then, the car has continued to lurch intermittently — for example, when backing out of a parking space or in stop-and-go traffic. In fact, approximately 10 minutes before the June 3 incident, the vehicle lurched several times while moving slowly in traffic. When the car began to lose speed during the most recent incident, I pressed the gas pedal all the way down, but it failed to respond at all. I believe the current issue may be related to the unresolved problems from last year and represents a significant and recurring safety concern. I’ve also read in Tucson owner forums that other drivers have experienced similar issues, suggesting this may be part of a broader, systemic defect. At this point, I do not feel safe driving this vehicle. I truly believe this car is a lemon. This vehicle is still at the dealership, but they have not given me any updates yet.

As I was (very slowly) pulling into a parking place at a park near my home and I was braking to come to a full stop, the car suddenly lurched forward, jumped the parking place barrier, and hit a tree. The front end of the car was badly damaged and the airbag opened. I sustained injuries to my left hand and my chest, though nothing was broken. The car was towed to a body shop, where it has been declared not reparable. Photos of the car at the scene are attached. This accident seems to be consistent with reports/recalls of the Hyundai Elantra of unintended acceleration when releasing the brake. We did talk to police shortly after the accident but we are unsure if they filed a report.

1) Transmission: while driving car jerks. when I’m accelerating from a stop sign or stop light the wheels kind of feel like they’re spinning/shaking and driving over gravel when I accelerate, before it actually starts and shifts gears. Car accelerating but not moving. 2) Not safe. Almost hit other cars around and people. 3) Dealer confirmed and replacing with new transmission. 4) No warning signs

My son was backing out of a parking spot at a strip mall. He released some pressure on the brake and indicated that the car lurched backwards and even though he reapplied full pressure to the brakes, he hit the car at the curb resulting in damage to our Tucson, but luckily not the to the other car. The Rear Cross-Traffic Collision-Avoidance Assist system did not engage, but my son indicated that the rear distance warning system did beep. I am concerned due to the sudden acceleration/lurching incident my son experienced and this is not acceptable in any car. I ask the federal safety agency to see if other Hyundai Tucson or Kia Sportage owners, especially with the Hybrid engine are experiencing this.
