| Jul 2024 | POWER TRAIN,ELECTRICAL SYSTEM,ENGINE | I was driving on the interstate at interstate speeds and the car started to lose power. I was able to steer the car to a safe location and call roadside assistance. It appears that the engine control system had a failure in one of the control modules. The problem was reproduced at the time that I dropped the car off with the service center. The history of the issues for the vehicle are available. My safety was put at risk because the car lost power at high speed and I was only able to limp to a safe location. No warning lights happened until the issue was already taking place. After being notified by my Hyundai app, I was able to discover that the vehicle had a history of having this code (I have only owned the car for 32 days) | Crash: No Fire: No | Unknown |
| Jun 2024 | ELECTRICAL SYSTEM | 2023 Hyundai Sonata Limited, 1.6 T. Battery discharged within 10 days while parked. This problem is well known to dealership. The dealership has to jump start cars and start them frequently on the dealership lot. It is impossible to park this model car at an airport or parking lot for more than a couple of days and maintain a battery charge. No warning or alerts. The problem is that the RESERVE amp hours of the standard stock battery is not adequate to supply the electronic drain of computers while parked. | Crash: No Fire: No | Unknown |
| Jun 2024 | STEERING,ENGINE,FUEL/PROPULSION SYSTEM | On two separate occasions, one at @9500 miles and the next at @19,000 miles the car engine started shaking and lost all power while driving. Unable to steer car. Both times towed to dealer and they say it needs new spark plugs and need to clean cylinders. They do not know root cause of problem and have not done any testing of the engine, no leak/compression testing. Dealer refuses to cover cost of repairs saying out of warranty but cannot give any assurances this won’t happen again. I’ve requested they contact Hyundai engineers to find out what’s causing this and, to date, they’ve done nothing. Vehicle is unsafe to drive and is still at dealership with no reason to underlying issue. | Crash: No Fire: No | Unknown |
| May 2024 | POWER TRAIN,ENGINE,FUEL/PROPULSION SYSTEM | The car would not accelerate, nor switch gear while I'm driving middle of the highway. The car engine started to shake after my car wouldn't switch gear. The car engine would not start after turning the car off and caused a engine misfire. The transmission gear has a hard time switching gear from 0-40mph. This same incident occurred twice since purchasing the car in late November 2022. | Crash: No Fire: No | Unknown |
| Apr 2024 | STRUCTURE | See attached document for complaint | Crash: No Fire: No | Unknown |
| Apr 2024 | ELECTRICAL SYSTEM,VEHICLE SPEED CONTROL,ENGINE | I have had three occasions where the dashboard lights would flash and the car would lose all power. The first occasion occurred on December 29th at around 12:20 pm at a crowded intersection. The dashboard lights lit up and all of a sudden the car had no power at all. I managed to get it through the intersection and pull it off to the side of the road. To start it up I have to TURN OFF THE CAR by putting it in park and start it up again. This is stressful and terrifying to think about if this had happened on the freeway. Additionally, I took the car to get serviced and was charged a $1,800 bill to fix it in January. This repair took two weeks to complete. The car has since turned off two additional times on February 15th going down a hill at 40 mph and March 26th on a mountain road going 60 mph. I am very concerned this will happen on the highway and I will get into a serious accident or worse. To make matters more difficult, I have taken the car back to the Hyundai dealer again to have it looked at in April and will most likely be without the car for at least another week. I bought the car brand new and the check engine light has gone off four times since then. | Crash: No Fire: No | Unknown |

| Mar 2024 | FORWARD COLLISION AVOIDANCE | This is the 3rd time it happened to me. I was driving on the highway at speed 60-70 and a flash came across my dash that said emergency brake warning and my car started slowing down. I panicked and pulled over the road. The warning came on so fast and not even a min it stood on. It went off within 5 seconds. This is a safety hazard and can cause death when this happens. Please issue a recall for this to be fixed because this is dangerous to me and other drivers. I want my money back because this is the manufacturer defect or issue. They need to correct this before fatalities happen. | Crash: No Fire: No | Unknown |
| Feb 2024 | FUEL/PROPULSION SYSTEM | Had been traveling for approximately 2.5 hours in a winter storm, pushed on brake to slow down and park and the car started to chug. Turned car off and then back on again. Car would not start and had to be towed to nearest Hyundai dealership. There were no warning signs at all, car just suddenly quit. We were later informed that it was the fuel injectors. We were very fortunate that this did not occur in a place with no cell service on a very frigid, stormy night. | Crash: No Fire: No | Unknown |
| Feb 2024 | EXTERIOR LIGHTING,ELECTRICAL SYSTEM | Instrument cluster lighting is too bright even on lowest setting. Combined with poor side visibility from headlamps it is easy to hit object or pedestrians when turning on unlit areas. Have run over a curb three times and damaged two wheels because they can't be seen from the overly bright instrument lighting at night. | Crash: Yes Fire: No | Unknown |
| Jan 2024 | ENGINE,FUEL/PROPULSION SYSTEM | Driving going 30 mph, vehicle stopped accelerating. Error code was Engine Control System failure. Codes P2178, P0301 and P0087F0 were shown at dealership. Car was taken to dealership for repairs where the fuel injector on cylinder #1. 16 days after receiving car back, we went to start the car and it wouldn't start. After several attempts, gasoline began spewing from the car leaking an entire tank of gas on our garage floor and driveway. Very dangerous! Being towed to dealership again today. | Crash: No Fire: No | Unknown |
| Jan 2024 | FUEL/PROPULSION SYSTEM | I was traveling on the freeway when I began experiencing erratic acceleration, around which time the check engine light came on. I took the next exit, and continued to experience the same symptoms, as well as rough idling, and a bit of smoke. The car was towed to the nearest Hyundai dealership where the fuel injector was replaced under warranty. | Crash: No Fire: No | Unknown |
| Nov 2023 | FUEL/PROPULSION SYSTEM | Took a trip to the grocery store, and started up my car when I got back. The engine turned over but after a few seconds, it stalled. Tried this again, but lightly pressed the accelerator. This raised the RPM, but it dropped quickly and stalled the engine again. Made a couple more attempts after and eventually, the engine light came on. Shortly before this incident, I had about 10-15% of gas left in my tank. After this happened, bluelink reported that I had 1% left. Got the vehicle towed to the dealership, where they confirmed the condition and found that the fuel injector for cylinder 3 needed to be replaced. I consider myself lucky that this happened while my vehicle was parked. This would've been a huge safety concern if it happened out on the road. | Crash: No Fire: No | Unknown |

| Oct 2023 | STRUCTURE | MY 2023 HYUNDAI SONATA LIMITED HAS AN ISSUE WHERE WATER ENTERS THE REAR LEFT DOOR AND GETS TRAPPED BETWEEN THE LOWER DOOR SEALS. WATER POURS OUT WHEN THE DOOR IS OPENED. A GOOGLE REVIEW OF "SONATA REAR DOOR LEAK" SHOWS THIS IS A WIDE SPREAD ISSUE WITH THIS DOOR AND CAR MODEL. IF THIS WERE TO OCCUR IN A NORTHERN CLIMATE THE DOOR WOULD HAVE ICE COLLECT BETWEEN THE DOOR AND DOOR SILL AND PREVENT THE DOOR FROM OPENING IN AN EMERGENCY. GOOGLE SHOWS NUMEROUS PEOPLE HAVE TRIED TO GET THIS ADDRESSED . MOST WITH NO SUCCESS FROM HYUNDAI. I HAD TAKEN MY CAR TO COCONUT CREEK HYUNDAI IN COCONUT CREEK FLORIDA IN AUG 2023 AND WAS TOLD "THIS CONDITION IS COMMON TO THE MODEL". NO FIX ATTEMPTED. I ESCALATED TO HYUNDAI USA, AND THEY LITERALLY STATED THEY CANNOT SUPERCEED THE DEALER AND TO TAKE THE CAR ELSEWHERE. THEY IGNORE THE DOOR ISSUE AND ALSO STATED ON RECORDED CALL ( THEIR RECORDING) THAT THIS CONDITION IS COMMON TO THE MODEL. I FEAR THE FIRST ACCIDENT THAT THE DOOR CANNOT BE OPENED DUE TO INTERNAL ICE COLLECTION. PLEASE JUST GOOGLE "SONATA WATER IN DOORS" TO SEE HOW COMMON THIS IS! | Crash: No Fire: No | Unknown |
| Sep 2023 | POWER TRAIN | Transmission goes into limp mode Please note this is an N line and shift points are low taking off from a light vehicle goes into limp mode in first 150' cars to the rear almost ran into the back of the vehicle. Car is 2 days old and I have an appointment tomorrow to have it looked at. This sounds like similar problem that caused a recall last year on the 2022. This is a dual clutch auto. | Crash: No Fire: No | Unknown |
| Sep 2023 | SUSPENSION,SERVICE BRAKES | The brake rotors are faulty and become warped at 9k mile I now have 27k and are extremely warped causing braking issues at higher speeds. I have been waiting over two months for new rotors from the dealer with no word as to when they will arrive. If the vehicle is left un-driven for a couple days the rotors will become rusted. Even the brand new vehicles in the Hyundia showroom are covered in rust. The suspension of the rear shock are extremely weak and bottoms out on the smallest rut. Cornering I’m the vehicle is subject to enormous amounts of whee hop which could result in an accident. | Crash: No Fire: No | Unknown |
| Sep 2023 | VEHICLE SPEED CONTROL | My concern is a potential unintended acceleration forward as. I was. parking vechicle. Sudden burst of speed, went thru shrubbery and off a 2 foot wall. Felt as if we were taking off a runway in a plane. Car went nose up over the wall and then dropped into a neighbor yard digging a divot, ripping rear left fender and bumper with some undercarriage problems. My spouse and I were seatbelted and not injured. I can not recall any safety warning until car stopped and then do recall a message being on dash but cannot presently recall what it said. Vehicle currently being worked on at collision center where Insurence Appraisor gave go ahead with estimate to repair damages | Crash: Yes Fire: No Towed | Unknown |
| Aug 2023 | VEHICLE SPEED CONTROL,ENGINE,FUEL/PROPULSION SYSTEM | Purchased a new Hyundai 2023 Sonata from McGovern Hyundai Rt 2 May 22, 2023. After two weeks of driving the vehicle, I noticed it hesitates when I push down on the gas pedal. I had planned to have the dealership take a look but have a very busy schedule, the issue continued each time I drove the car to the point it was hesitating, basically pausing as I cross intersections. On the 26th of July I was driving on the highway, as I started to experience issues when stepping on the gas. Entering a tunnel in Boston, I pushed down on the gas pedal and noticed the car was decelerating, I was losing speed, in a panic in the center lane of the tunnel, I was able to get the car over to the far right. The car was shaking aggressively then finally just gave out and I called 911. They towed the vehicle to the police headquarters, I called Hyundai for assistance. Had some hiccups but two days later they were able to service the vehicle, supposedly found a faulty fuel injector. They changed out the 1 faulty injector test drive and said the problem was fixed. I picked up my car on July 28th 2023. There is something still wrong with the car, it still has some hesitation and now misfires. Have not heard from Hyundai, I was assigned a case manager and told someone would follow up, no one has reached out. So lucky my children were not in the car and that i'm safe. I could have been killed, others could have been hurt/killed. This should not happen to brand new cars. | Crash: No Fire: No | Unknown |
| Jul 2023 | UNKNOWN OR OTHER | The power-operated driver seat has moved on its own, without warning, while the vehicle is in gear, potentially moving the driver away from being able to reach the brake pedal or otherwise control the vehicle. The vehicle uses seat position memory pre-sets and/or driver profiles, such that even if a new driver sets the seat position manually or by using a pre-defined memory setting, will move the seat to the position it was last driven in. The driver can stop the seat from moving further by either activating the seat position controls or by selecting a seat position memory setting. | Crash: No Fire: No | Unknown |
| Jul 2023 | ELECTRICAL SYSTEM,UNKNOWN OR OTHER,ENGINE | When I approach an intersection to stop my car auto shut off engages. When trying to hit the gas to release my car from auto shut off the emergency auto shut off engages and I must put my car in park. Turn the ignition to off and then crank my car back all the way on. Release the park and drive. This happens intermittently for several weeks and I’ve almost been rear ended several times. I have taken the car to a Hyundai dealership for the issue and they tell me nothing is wrong. | Crash: No Fire: No | Unknown |
