2019 Hyundai Tucson: jerking or lurching

Filed Jan 22, 2026 · Electrical, Steering · ID

On three occasions while the vehicle was idling, the dashboard screens and interior lights went completely black, and the steering wheel jerked abruptly in my hands. This sudden electrical failure creates a serious safety concern, particularly if it were to occur while driving at higher speeds. The dealer has not been able to reproduce the problem. There were no warning lamps, messages or other symptoms prior to the failure. There were no warning lamps after the problem occurred. The vehicle has been inspected multiple times by a Hyundai dealership. On one occasion, the dealership retained the vehicle for approximately two months but reported no definitive findings despite error codes being present. On a later visit following another failure, no error codes were recorded. The dealership replaced the head/stereo unit and confirmed no active recalls, yet the issue continues. This problem first occurred while the vehicle was covered under an extended warranty, but due to its intermittent nature, it was not resolved before the warranty mileage threshold was exceeded. I have since found numerous similar complaints online from owners of the same model year describing electrical blackouts and steering-related concerns. A Hyundai service manager advised me to dispose of the vehicle, which further reinforces my concern that the defect may be known but unresolved. I believe this issue represents a potential safety defect and warrants documentation and review. Thank you for your attention to this matter.

I was merging onto a highway at high speeds when the car stuttered. The check engine light began to flash and I lost acceleration. I could push the gas pedal to the floor and the car would not accelerate at all. The car lost it's speed and I could not go anymore than 30mph, and it would not go higher than 2rpms. It put me and my baby (who was in the backseat) in danger as we were going fast on a highway and out of nowhere the car lost speed and I could not accelerate. I could've easily been hit by another driver going the regular speed limit. I drove it to the dealership that just happened to be down the street, and the car struggled to accelerate from a complete stop, as well as in general. From a complete stop, the car would sputter and jerk when pressing on the gas pedal. The dealership diagnosed it as a faulty Knock Sensor. They said they would replace the sensor as it was still under warrenty. When I left the dealership, the check engine light was off and the car was driving fine. Fast forward to the next day, I was driving again on a highway at about 65mph, when the SAME thing happens. The car stuttered, lost all acceleration, and the check engine light was flashing. I ended up driving it home (about 10 miles away) and the whole time I could not go faster than 30mph without the car shaking. This time the car would not go higher than 1.5rpms. I checked the engine at home and a P1326 code came up, which is a code for the Knock Sensor. I called the Hyundai dealership that I originally went to and they said there was nothing they can do about it at the moment since they had just replaced it. Prior to all of this, there was no warning sign at all that this was a potential hazard. It happened so suddenly and both times it happened put me in a dangerous situation.

2019 hyundai tucson limited. Sporadic hesitation acceleration from starting from a complete stop. I've had the car since june and have less than 3500 miles on it. When you start from a red light the car will jerk and hesitate, almost like it's out of gas but then in the middle of the intersection it will accelerate like normal. This has only happened to me while in normal driving mode. It hasn't done this while in sport or manual shifting mode. I had to select a date of when this happened but it originally started around mid july and sporadically to this day. It happens randomly but when it does it happens at consecutive stop lights and multiple times on the same day. This isn't a dct, so hyundai, nor the dealer can say I'm driving the car incorrectly. Pretty disappointing to have my first ever brand new car have a serious issue like this.
