Hyundai Sonata Hybrid jerking problems

Filed Jul 24, 2026 · Transmission · MN

While driving and everything is going along fine it will suddenly jerk and make a sound as if I've been hit behind. I'm not sure if it's part of the detached shift cables or transmission or something else. Sometimes it will jerk violently while going uphill also.

The car will randomly lose acceleration and jerk forward. It will make a beeping noise while the hev system warning flashes on the dash. It also says to turn off engine. While the warning is flashing and engine light is on it goes into a limp mode and you have limited acceleration. It has almost caused multiple wrecks when I go to acceleration from turning or at lights in traffic because I cant go over 20-30 mph. I have turned the car on and off and the hev system and engine light turns off and the car continues to work normal. It eventually comes back on and does the same loss of power/hev warning. It will be random and does not matter on how fast you are going to trigger the warning lights and loss of power.

The vehicle went in for repair at the dealership early July for a check engine light and DTC error code. It was revving high after being driven for more than 20 min or so and wouldn’t get to above 60 mph. Jerky, dangerous acceleration and deceleration seemingly out of nowhere. The dealership replaced the fuel pump which is what they said was causing the error. Today on August 10th, check engine light popped up again with a DTC error code. Weird acceleration and deceleration and general jerkiness when driving. Scheduled service appointment for next week.

Engine Shut Off Without Warning problem of the 2017 Hyundai Sonata Hybrid While driving the car on the freeway, it will jerk forward and then shortly after lose power. I pull over (luckily haven't been killed yet) on the side of the freeway. I've taken my car to a Hyundai dealership third times. All Three time I was stranded on a busy california highway. I have looked into this warning over a year and no one seems to know the problem. This should be a recall and all Hyundai dealers should be made aware of what this warning is. We as Hyundai owners need answers and help.

Same problem with this 2018 Hyundai Sonata Limited Hybrid engine as the already recalled 2017 Sonata’s with the same 4 liter/direct fuel injection engines. At approximately 69,000 miles the problems and check engine light analyzed was done by Auto Zone and Brandon Hyundai (3 times each and finding additional problems each time). I have documentation. P1326 Knock Sensor indicated engine failure problems P0302 Cylinder 2 misfire (occurred next day after repair of this part) U0293 Lost communication with HEV Powertrain control module ( not charging hybrid U1004 H-CAN C135B-08 no code explanation given C1612-08 CAN time-out TCM C1611-08 CAN time-out EPS ECM C1614-08 CAN time-out HCU C2229-08 Towed to dealer for repair. These problems occurred from 4/18/22 to 4/27/22 3 times in less than 2 weeks. car still in service dept today 4/30/22 with no resolution. Failures continued to escalate after each service. Went into “Limp Home Mode” twice. Very unsafe to drive. Stalled, jerked and speed reduced. This happened on I-75 twice and once on Hwy 674. Felt in danger each time (especially the last time on 4/27/22). Turned on caution lights and tried to safely pull over. Check engine light blinking and many other engine lights came on. Brandon Hyundai said engine may need to be replaced, but then they want apply “bandaid temporary fixes”: like replace Cylinders again and now Knock Sensor; instead of addressing safety issues of a failing engine. These engines are unsafe! They need to be recalled and replaced before they could causing major accidents due to engines poor performance as it’s failing. The jerking and stalling put me in danger prior to being able to restart the engine to get off the road. Are these a possible fire hazard as well? I’m scared to drive it, whenever I get it back from the dealers service department!

On 04/09/2022 around 6:30 PM EDT, while driving on the Florida Turnpike at the posted 70 mph in Orlando FL, the 2015 Sonata Hybrid suddenly shut down in the center of 4-lanes with heavy traffic. The engine would not run and only sputtered and jerked when I gave it any gas. The display screen lit up with multiple failure symbols including the Hybrid System failure, lane detection failure, and several others. I exited the Turnpike and had a local auto store scan the vehicle finding the following DTC’s: 1. P1326: Excessive connecting rod bearing wear 2. U0293: Lost Communication with Hybrid Powertrain Control Module 3. U1004: Not certain The vehicle was checked and found to be full of oil. The vehicle was serviced at the Hyundai Dealer on 02/25/2022 where they specifically updated the “Excessive connecting rod bearing wear” knock sensor software along with a turn signal issue. Having the engine go into a default mode at 70 mph in heavy traffic was a near disaster. A simple warning would have been adequate to all me to safely navigate to the roadside.

While driving the car on the freeway, it will jerk forward and then shortly after lose power. The car shows the battery as being barely charged. I pull over (luckily haven't been killed yet) on the side of the freeway. Let the car sit for a few minutes, restart it and the battery is half full and the car is driveable. I've read online that this is a common issue with 2012 hyundai sonata hybrids. I've taken my car to a hyundai dealership twice, and they can't find anything wrong, diagnostics show its fine. The second time I took it in they replaced the battery located in my trunk for $485. That did nothing, as the car is still randomly shutting off, and most times in the most dangerous areas of the road. I don't think hyundai will do anything about this until numerous people are killed. Forgot to mention that sometimes when it shuts down the check oil light comes on. I've had the oil replaced and the oil sensor, so thats not the issue.
