2022 Hyundai Tucson Hybrid Driver assistance Problems

While driving my 2022 Hyundai Tucson Hybrid, the vehicle suddenly lost power, began shaking, and all warning lights illuminated at once. The car would not accelerate properly and became unsafe to operate in traffic. After pulling over and restarting the vehicle, the warnings cleared, but the issue has occurred more than once. It first occurred 3/25/26. The dealer was not able to reproduce the issue but found numerous faults and reset them. This is a serious safety concern because the vehicle can unexpectedly lose motor power while driving, creating a risk of collision. The problem is intermittent and unpredictable.

The blind spot warning went off and locked all the brakes up. We were not able to move the vehicle and could not even pull off the road out of traffic. There is no way to disable the brakes when the computer or sensors are malfunctioning. We had to get the vehicle towed.

Hyundai has a service bulletin for their 12V battery but isn’t notifying owners. Today my vehicle stopped working and lost all acceleration on a busy 3 lane street that is 55mph. I was able to limp it to a left turn lane where I had to research the issue and found many others had instances like mine. The battery stops working and subsequently stops the vehicle from accelerating and tells you to ‘stop safely’ with no warning or indication that you’re about to stop moving on a road.

A week ago, I was driving my 2022 Tucson Hybrid Limited on the highway on my way to work around 7:50 a.m. It was a bright day, good weather. I was in the center lane when my car suddenly braked HARD and came to a stop on the highway! My foot was still on the gas pedal, but the Automatic Emergency Braking light was on. I panicked because I had no control over what the car was doing. Thankfully, I was not rear-ended and didn't cause an accident. I put on my hazard lights, shifted into park on the highway's center lane, then back into drive and it seemed fine. There was not really any traffic in front of me that I remember, but there were some cars on either side and behind me that had to swerve around me. I don't trust this car anymore. It is going to get me or someone else killed. I took it to the dealer 2 days ago and the initial inspection didn't show any problems or error codes. They told me I could have it back since there didn't seem to be a problem or they could give me a loaner car and keep testing my car. I have a loaner. I hope they find something wrong with the car, otherwise, I am afraid of my car getting me or someone else killed. I am especially scared after reading about all the others here who have had this same issue.

On August 1st I was on the highway at 55 mph when my 2022 Hyundai Tucson decelerated to 20 mph and would not go faster. This occurred on the highway at 5:45 pm. This placed myself and others in danger as I was on the highway in the center lane at the time of the deceleration. After turning the car in, the dealership returned the car with no repairs but stating that I engaged a button that caused a limit to the car's speed. I didn't understand but took their word. I drove it from the dealership to the store and home. The very next morning while taking my grandson to school at 5:15 am the car decelerated from 45 to 20 mph with my grandson inside the car. This placed myself and a family member in danger along with cars around me. Each time I had to drive to the dealership in unsafe conditions. They stated that I was not engaging the brake enough to charge the battery. I do not know of ANY documentation stating the number of times the brake must be engaged per drive. I have never heard of such engineering that allows a car to only go 20 mph and create a hazard for the occupants unknowingly. The dealership has stated that refuse to fix the problem but I should engage the brakes more often when I drive. The car has spent several months in their care due to continued repairs over the time that I've had it and is currently their because of the engine light being on.

While driving over 50 mph the emergency brake has initiated 3 times in a 4 month period. There are no cars in front of my vehicle and it is not the collision warning but it will flash on the dash the the emergency brake is engaged in red, it will make a warning beeping noise and the car will brake on its own.

Driving at night when it snows is unsafe. The forward collision warning sensor is covered with snow within minutes and so are the headlights. They are placed in the front bumper and covered with snow because by their design they are not flush with the bumper. They are sitting deep within the bumper which creates a trap for snow and slush. I hade to stop every few minutes to clean the headlights from snow because they were covered and I couldn’t see anything in front. It’s a design flaw.

On 9/3/23, driver was waiting at a stop sign to turn left. When driver accelerated into the highway, there was no power and the vehicle would only go 5-10 mph. Warning lights came on to check the hybrid system with the HEV indicator light. Driver pulled over. Restarted car and engine was stuttering. Was able to drive a few miles to a safer location. Started car on 9/4/23, again it had a rough start. Driver waited until the vehicle sounded normal. The vehicle immediately lost power and could not accelerate when on the main road. Called Hyundai and they were unconcerned. We are in remote Alaska, 250 miles from a dealership. Because it happened on a holiday weekend, we have been unable to contact the service department yet. Vehicle is available to be inspected. Safety is a huge risk because the car suddenly stops propelling forward. I'm afraid we will get rear-ended because of the sudden loss of power. It is a danger to ourselves and others. I'm also concerned that we will be stranded because the car has to be stopped when this occurs. We were supposed to be enjoying a trip for a week, and now we don't trust the vehicle and will likely need to go home early and lose hotel costs. This issue will wind up killing someone because there are reports that these Hyundais are stopping in the middle of the highway. Please hold Hyundai accountable.

The car shook and then lights and alarms went off indicating something went wrong with the hybrid system. The car stopped accelerating, would shake, and then accelerated no more than 10 mph. It was absolutely crazy! Luckily, the highway that I was traveling on was not a busy one at the time because all I thought was this could have been a major accident if on a fast moving freeway. I managed to pull over and started reading online about this issue occurring with other customers who purchased the same or similar vehicle. So, I found a post and had shut the car off for 5 minutes, then restart and sit for 10 minutes, and then the car should work. It did! However, during the time of waiting I did reach out to the dealership and they said if the car is working there is nothing they could do. So, I assumed it was safe to use travel to work for a meeting and set up my classroom for the start of the new school year. On my way home from school, the issue happened again. I immediately contacted the dealership and was able to get the car to them. They started running diagnostic tests and currently have the vehicle on hand. However, I don't really feel safe now with this car given the circumstances. What if this should happen again? What if this happens to me or someone else who is traveling on a busy highway and it causes injury or even death to an accident. The engine light came on, battery light flickered on and off, the car shook, the car's HEV system warning was going off, etc. Please help and look into this matter. I do not have any documentation of repair as the car currently sits at the dealership, but I was so upset thinking about what could have happened and felt the need to report the issue.

The vehicle has had 2 instances of accelerating extremely fast unexpectedly. Once when I was backing up and lightly pressed the accelerator the car shot backwards in a fast speed. The second time I was parking and lightly pressed the accelerator as I was pulling into the parking spot the car sped super fast crashing my car into the pole and damaging my front car bumper.

On at least six occasions since I took possession of this Hyundai vehicle the vehicle has been automatically slowed down accompanied by a "25 mph speed limit" sensor light coming on - and most of these instances could be dangerous because they were not in low-speed zones. This has happened in low-speed zones or near those, in particular on/near a college campus that I drive through or near, but several times this happened when I was in a 35, 45, or 55 mph zone. In fact, yesterday around 6 p.m., after starting the car a minute earlier I pulled out of a driveway onto a rural highway (55 mph) and the car slowed immediately and that warning came on and it did not go off until I shut the car off about 5 minutes later. This was nowhere near a low-speed zone, it was several miles from one. When this has happened in higher speed zones the only thing that makes sense sometimes is to try and "override" the setting by putting the accelerator to the floor, but that isn't ideal as I have discovered, because while it will eventually override the sensor it also causes the car to rocket once it does. Besides that, the car can be shut down and that seems to reset the sensor as well, but sometimes you can't just pull over and restart.
