ELECTRICAL SYSTEM, VEHICLE SPEED CONTROL, FUEL/PROPULSION SYSTEM
While on cruise control when climbing a hill, a warning appears telling me that the EV has failed and that I should stop driving the vehicle. At the time the warning appears the cruise control shuts off and the car slow dramatically. All 5 times this has happened the vehicles behind me have had to slam on their brakes in order to avoid running me over. Once it was a triaxle dump truck, fully loaded, he went off the right side of the road and almost hit the guardrails to avoid the collision. The car has been tested at our dealership (Jenkins Hyundai) and they have confirmed the issue.

ELECTRICAL SYSTEM
Owner of 2021 Hyundai Hybrid Ioniq. Auto hold and EPB (electronic parking brake) malfunction lights come on randomly. After inspection at dealership electronic brake control module needs replacing, not communicating with car Module is currently on backorder and may take six weeks for part to come in. Dealership's service dept. fully understood what repair is needed and is taking care of the problem. We were strongly advised NOT TO DRIVE the car until repaired. Vehicle could possibly auto stop going at high speeds. Dealership provided a rental car until the repair is made. This is a great dealership , one that has concern for the consumer's safety over their bottom line. We'll know in about six weeks if replacing the module fixes the problem.

VEHICLE SPEED CONTROL, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
During a highway trip that was bumper to bumper traffic at approximately 15mph, the car suddenly would not accelerate while operating on gasoline (not electric). The engine revs would increase to maximum without movement from the car (as if the car was in neutral). After checking the gear lever to make sure it was still in D, tried to accelerate again and engine rev high without movement. Eventually car came to stop with brakes, and the car could move on electric power (in hybrid mode), pulled over and turned off the car to visually inspect. After not identifying anything, turned on car and operation resumed to normal and would accelerate on gas power.

Hyundai has no date for remedy. Theres a remedy for same car but different vins. They told me our car was produced in a different manufacturer place so no remedy and they said it is what it is. It has almost been 30 days and I cant use the car for my business when this safety recall is out that was fixed in 2018.

POWER TRAIN, ELECTRICAL SYSTEM, ENGINE
In the middle lane of a multiple lane highway, it suddenly gave a very confusing warning on the dashboard. It lost power and slowed down quickly to below 40 mph. It didn't help to press down the gas pedal. I was forced to switch from the middle lane to the passing lane in order to reach the shoulder. The car was side swept by another car in the passing lane because it was at low speed. Once it reached on the shoulder it stopped completely. If it gave a clear warning, for example, "pull out immediately!", and flashed the emergency light automatically, it might save a few seconds, and gave a warning to cars behind. It's a PHEV, and I believe that it used up the battery for driving but failed to automatically start the gas engine.

VEHICLE SPEED CONTROL, SERVICE BRAKES, UNKNOWN OR OTHER
One morning, my father turned on the car. It was still in Park. He and my mom heard a noise, as if my dad was pushing on the gas pedal, but he was not. They turned off the car, turned it on again, and everything seemed fine. After driving for a bit, my father was back home and parking the car. Because of the way the parking lot is, you have to go slowly, less than 10 miles an hour, pushing on the gas a little to go up and incline and then turn right to slide into the parking spot as you break to finally park. As he was pulling into the parking spot, the car suddenly accelerated uncontrollably, and crashed hard into the building ahead. It broke pieces of the building, and the entire front of the car is totaled. My parents saw fire under the hood and my mom suffered a hand injury. They are otherwise unharmed. I know Unintended Sudden Acceleration was an issue with Ioniq EVs from 2019. It looks like it is happening to the hybrids as well. Thank you for looking into it.

POWER TRAIN
While my wife and I were driving on the interstate, all dashboard warning lights came on at once, and the car began rumbling at regular intervals as it tried and failed to switch from electric vehicle (EV) mode to hybrid EV (HEV) mode, and the engine wouldn't start. At the same time, the power steering stopped working, the car struggled to go more than 40 MPH, and it started accelerating on its own and would not stop until I hit the brake. Each time the engine tried and failed to start, the car started accelerating again. I pulled off at a gas station, turned the car off, and called for a tow. I tried to turn it on again but got a "Check Hybrid System" message and could not start the car, so I had it towed to a dealer. They diagnosed it as a dead 12-volt battery; however, they had none in stock and would be unable to get one for 2 weeks, so they charged the 12v and told us we should be able to get home. It happened again a few hundred miles later, and the situation repeated itself. This 2nd dealer also diagnosed that the issue was the 12v but couldn't get one in for at least a week. We rented a car, drove home, and when the dealer replaced the battery, they shipped it up to us. A week later, the car's big battery (not the 12v) was failing to charge, so we brought it to another dealer. They claimed they had no trouble charging it and returned the car. Shortly after that, it died again, in the same fashion described above. We took it back to the dealer, and they had it for over a month, claiming they could not replicate the problem. They returned the car, having diagnosed no problem, so I drove around the dealer and replicated issue myself. It took 15 minutes for the check engine light to come on. I brought it back to the dealer. When they got in the car, the power steering was dead, and the car could barely move. They've now acknowledged that the problem exists and are trying to diagnose it for a 4th time (5th if you count when I was unable to get it to charge).

VEHICLE SPEED CONTROL
Driving on highway at 68 mph. Set cruise control and it raced speed up to 110 mph on its own. Cancelled cruise and tried to set at similar speed approximate 5 times with same result. Restarted car and gripe has not repeated in over 2,000 miles. Dangerous condition that should not be possible. Appears to be computer/software issue as no physical obstructions were present on cruise controls. I have a video of the incident, but cannot upload currently do to unsupported file type.

ELECTRICAL SYSTEM, VEHICLE SPEED CONTROL, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
Two different scenarios with this cruise control are problems with this vehicle. When it is raining the system with the cruise control does not work and the shop told me it happens with other vehicles. A warning light appears when this happens. This last time it was not raining and the cruise control quit working and the warning light came on as well as another system warning light. I showed the picture to the guy at the shop and he said after I showed him the picture he knew what to do, he had to reset the system. Yes, it’s available for inspection. When you’re driving in traffic on the highway going 65 and the car slows down for no apparent reason, that is a problem. The vehicle has not been inspected.

SERVICE BRAKES
The regenerative brakes had an error go off, which caused the brakes to stop working properly. This error went off twice, once in my driveway upon starting my car, then it reset itself. And again while driving, in which I nearly rear ended the car in front of me due to the brakes not working. Hyundai confirmed the error codes but could not reproduce. Hyundai eventually replaced components of the brakes, but I do not trust that it won't happen again. I wanted out of my lease but they refused and made me drive it again, even though I'm terrified of it happening again.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER
My horn failed and was replaced in March of 2021. It stopped working again in January of 2022. The dealer replaced the horn the first time and another horn is on order with an unknown date of when the part will be available. This is a safety concern for me. I drive in the country and many deer run in the road. There has also been an incident where a child ran infront of my car while in my home city. Not having a horn poses a risk to me and others. I would not expect a car that is less than 2 years old to have a horn go out twice. I have driven 50 years and have never had a horn break. There was no warning prior to horn failure nor do I know how long the horn was broke.

ELECTRICAL SYSTEM
The contact leased a 2021 Hyundai Ioniq Electric The contact stated that while the vehicle was parked, he attempted to open the driver’s side door using the key fob; however, the door would not open. The contact contacted Hyundai roadside assistance who assisted him in jumpstarting and recharging the batteries. The contact was still able to drive the vehicle. The contact stated that a couple of days later, the vehicle failed to start after several attempts. The vehicle was towed to the dealer where it was diagnosed that the mechanic switch that applied the emergency brake was not completely closed and kept the electrical circuit for the emergency brake activated causing the two batteries to drain. The vehicle was repaired. The manufacturer was notified of the failure and advised the contact that they would reimburse him for the vehicle rental expenses under the condition that he surrendered his rights to pursue reimbursement for the vehicle repair expenses. The failure mileage was approximately 3,400.
