On June 1, 2023 I was driving on a highway, suddenly lost the ability to accelerate, the car suddenly losing power and a warning message said to leave the road and have hybrid system checked. I pulled over, car idling, reentered highway only able to use low speed ( was 55 mph zone) to get to an exit a short distance away I had to be towed, the warning message still appearing at the dealership but no problem could be identified. This was an extremely dangerous situation, I have not had a problem like this again but remain concerned about a reoccurrence I have reached out to Hyundai about my concerns about 1) how roadside assistance was handled (response obtained) and 2) my concerns about this vehicle failure. I have reached out again this month to Hyundai, last contact they did not have the correct car or case number, have not called back since . This is case #21511789
2022 Hyundai Tucson Hybrid fuel system complaints

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.
05/11/2023 Driving on Highway (Work Zone) Dash Flashed Hybrid System Failure - I was in the fast lane with Tractor trailer in front ,behind ,and alongside me - Gas pedal stopped working at that point nothing worked - managed to coast to the shoulder (could have been killed) Had it towed to Hyundai - They checked the computer and said nothing was wrong . that means if we were killed - Hyundai would be off the hook and they would say human error because they said no faults were stored and the codes were clear
I turned right into my driveway at a slow speed. As I went onto the driveway, the car surged forward. To avoid driving into the garage door, I turned to the left to drive along the side of my house thinking I would be able to stop it. I kept hitting the break but the car kept going. When the vehicle did not stop, I steered to the right because I thought it could be possible that my neighbor's dog could be in the adjacent yard (to the left of my house) The ground between the houses is pitched down (to the left) towards my house and I side-swiped the back half of the side of my house. Although applying the break, my car continued after sideswiping the side of my house with the front right side of my car and went into the house behind my house causing damage to that house. My car stopped when it went into the house behind my house.
HeV and engine light came on while car was in motion and immediately lost power/decelerated, causing traffic hazzard to other potential drivers due to sudden and unexpected change in speed and inability to move car out of road. There were no prior warnings. Car is in shop and available for inspection.
The contact owns a 2022 Hyundai Tucson. The contact stated while driving at an undisclosed speed, the hybrid alert warning light illuminated, and the vehicle then decelerated. The contact veered the vehicle off the road and turned the vehicle off and restarted the vehicle. The collision alert and check engine warning light illuminated. The vehicle was taken to the dealer where the contact was informed of an unknown issue with the power train however, the contact was informed that failure was corrected independently and that the check engine warning light needed to be reset. The vehicle was repaired; however, the failure recurred. The manufacturer was notified of the failure and provided a case number. The failure mileage was approximately 4,000.
The car slowed down so I tried stepping on the gas pedal and noticed it wasn’t working, then I tried stepping on the brake pedal and it didn’t work neither. The car slowed down and called it to get towed.
Attempting to enter I-295 South in Portland, ME at Exit 7 on March 18, 2023. We were in our 2022 Hyundai Tucson Hybrid Limited with approximately 6,000 miles. I tried to accelerate from the ramp to merge into traffic. The vehicle would not accelerate at all. I made several attempts to accelerate and nothing would happen. Pulled into the breakdown lane while applying pressure to the accelerator but it would not accelerate. The vehicle was in EV (electric vehicle) mode. After approximately 1 minute the vehicle did accelerate. No further problems that day. We called the dealership immediately and left a message regarding the incident. On Monday March 20th We followed up with the dealership and scheduled an appointment for the next day On the 21st of March We dropped the vehicle at the dealership. We picked it up at the end of the day and they told us they installed a software update TSB 23-EE-002H to repair the issue.
I am an active-duty service member who purchased a new 2022 Hyundai Tucson Hybrid on 16 October 2021. The car occasionally makes a strange humming noise while the vehicle is completely turned off. I recorded my car making this strange noise, and the video recording can be seen at https://youtu.be/bY8GJenoWBQ. I had previously notified Hyundai Maintenance of this during a scheduled vehicle check; nothing was done to resolve this matter. The advertised fuel economy on this car is 36/37/37 (city/combined/highway) Miles per Gallon. I am currently getting 28 MPG (see attachment), which is approximately 30% below the advertised fuel economy. Since I purchased this vehicle, it has consistently delivered a poor fuel economy well below the advertised fuel economy. After trying to resolve the poor fuel economy issue with Hyundai for 9 months (see attachment), I reached out to the Better Business Bureau seeking a resolution. On 17 November 2022, I was notified by the Better Business Bureau that Hyundai rejected my proposed resolutions of Hyundai repairing the car under manufacturer warranty or replace it if unable to fix the poor fuel economy, as well as reimburse me for money spent due to excessive fuel consumption. Additionally, other persons have reported their Hyundai cars delivering a fuel economy much lower than advertised (visit https://www.reddit.com/r/Hyundai/comments/nwayqv/2022_tucson_hybrid_poor_gas_mileage/). I have the perception that Hyundai lied and deliberately deceived me. Something is wrong with my car, and Hyundai has been either incompetent or unwilling to repair the issue under the car manufacturer warranty. I believe that it's important to hold companies such as Hyundai accountable. Otherwise, it would have no incentive for doing what is right. I request your assistance with investigating, and if possible, taking actions to hold Hyundai accountable for deceiving consumers by exaggerating its car fuel economy.
