  Transmission problems began around 60,000 miles (but we didn’t know what it was) — jerking and hesitation, that worsened over time. We took the vehicle in (November 2025 ),at around 109,000 miles at which time they couldn’t find anything. I took it back in December and they recommended the spark plugs. We took the car back again in March at which time they recommended other little things. We took the vehicle back yet again on March 10 and told them to check the transmission. The dealership said “ As far as the transmission, we cant get it to really do anything so if you dont have an extended warranty we would recommend waiting until the issue gets worse and then put a transmission in it unless you wanted me to get you a price on it”. The vehicle has been at an authorized Hyundai dealership since the third week in June 2026 (because I wanted them to tell me why I had a bad transmission in my three year-old car) while awaiting resolution from manufacturer's consumer advocate (they took 60 days to resolve absolutely nothing). A replacement transmission was authorized on August 6. The manufacturer-supplied replacement was installed and found defective on August 27 (when I asked to test drive the car with a mechanic) it would not shift past 3rd gear. When I asked the dealer why I was not informed, prior to my picking up the vehicle, he told me “we don’t tell the consumer every little thing”. A second replacement was supposedly ordered from the manufacturer August 27, and is still not installed as of October 17. The manufacturer told me “the part was in and being worked on” 10/2. This was false. Th dealership is holding my vehicle hostage and demanding $5,786 for the defective replacement. My vehicle cannot be retrieved. The original transmission that was jerking and hesitating was a hazard to myself and other drivers around me, especially on the highway. The dealer even told me “ this is the third defective manufacturer replacement part received this month”.

  While driving at highway speeds, the emergency brake system will apply and alert me. It’s happened twice now in the last 3 weeks. I’ve experienced a random loss of power while driving on the highway with no check engine light on the dashboard. Lastly, at lower speeds the car will randomly jerk while accelerating with no lights on the dashboard as well. I’ve gone to the dealership but they wanted to charge me a diagnostics fee to first look over the vehicle, which I don’t feel I should be on the hook for since the issue isn’t user caused.

  I own a 2023 Hyundai Sonata SEL. Over approximately three years, the vehicle experienced four separate incidents involving sudden loss of engine power and recurring fuel injector/powertrain problems. Three of these incidents occurred while the vehicle was being driven on interstate highways, creating serious safety concerns. The first incident occurred on XXX, on [XXX] [XXX]. My daughter was driving the vehicle at the time when it suddenly lost power while traveling on the interstate. She had to maneuver the vehicle to the shoulder under unsafe traffic conditions. The second incident occurred on XXX, on [XXX] near [XXX]. I was driving the vehicle when it again experienced sudden loss of power while traveling at highway speed. The third incident occurred on XXX, in [XXX]. The vehicle experienced another significant power-loss event and required roadside assistance. The fourth incident occurred on XXX, on [XXX]. The vehicle again experienced a sudden loss of engine power while I was driving on the highway. Despite multiple repair attempts, including repairs related to the fuel injectors, the same or substantially similar power-loss problem continued to recur. Because the vehicle has repeatedly lost engine power while being driven, including multiple incidents at interstate highway speeds, I believe this recurring condition presents a serious safety risk. I am reporting these incidents so NHTSA can evaluate whether this may represent a broader safety-related defect affecting this vehicle model.

  This is an extremely common issue plaguing Hyundai & Kia vehicles with the Theta III 2.5L Turbo engine, Such as Kia K5 GT, Hyundai Sante Fe, Hyundai Santa Cruz, & Hyundai Sonata N-Line. Its a failing ITM (integrated thermal management) unit or otherwise known as an ITMS unit. There is a rod within the ITM that prevents proper control of the flow of cooling the oil and engine coolant of the engine. Results in Cooling issues, such as a cold lower radiator hose while the engine is hot, or 'limp mode' during acceleration, that causes a sudden loss of power while trying to merge on the expressway. There has been other Kia models and years that have had TSB's related to fixing this issue, but Hyundai has released nothing. I have uploaded an example of one of the TSB's that do not apply to my car. Technical symptoms often include: Fans running 100% full duty (high) while the lower radiator hose stays cool. Or Fuel dilution or a 'rich' running engine. Because the engine is overcooling that keeps the car's fueling rich and in a open loop mode affecting emissions and contaminating oil. Personal Details of exactly what happened when i noticed mine was failing. I ran home on my lunch break, and while accelerating on a ramp to get up on a highway, my car started beeping and flashing "Engine Overheated" and i immediately let off the gas with preparation to pull over. The second i left off the gas, the coolant temp within 1-2 seconds went from a little over 3/4 the way up the gauge back to normal a little below half temp. I resumed driving a 3 mile drive back to work, with it showing normal temps the rest of the way. I popped the hood when i got to work to see if coolant was low, and it was completely normal, a little over halfway between the min/max lines. The car continues to run hot, often with the cooling fans running at 100%.

  Was driving and stopped at a stoplight. When I went to drive it started sputtering and if I wouldn’t have driven into a gas station, it would’ve given out in the middle of the road. It wouldn’t let me switch to drive or reverse , only neutral or park. It threw a code P0301, cylinder 1 misfire. Had to get it towed. Now I have to get my spark plugs and fuel injectors replaced.

  The contact owns a 2023 Hyundai Sonata. The contact stated that while his wife was driving at an undisclosed speed, the message "Engine Overheated" displayed. The contact checked the Hyundai app, but it showed no failure. The contact's wife drove to their son's residence, who inspected and discovered that there was no coolant in the engine. The contact's son added coolant to the engine. The vehicle was taken to the dealer, who replaced the coolant valve, exhaust muffler assembly center, clamp assembly exhaust pipe, two gasket exhaust pipes, and added coolant. The contact related the failure to Technical Service Bulletin: 23-EM-009H (EHRS Coolant Leak Repair); however, the vehicle was not covered under the TSB. The manufacturer was made aware of the failure, and a case was filed. The failure mileage was approximately 18,500.

  Battery Management System completely exhausting the 12V battery resulting in the car acting as if it has no power. When this happens, you can't unlock the door or open the trunk. On two separate occasions, I have encountered a complete loss of power in my Sonata Hybrid, preventing me from unlocking the trunk or doors upon returning from extended trips. The first incident occurred after a ten-day absence last Fall, and the most recent was on Saturday, March 14, 2025. During the latest incident, I returned from a seven-day trip and found my vehicle parked at Orlando International Airport. Upon approaching the car, I anticipated being able to unlock the trunk, load my luggage, enter the vehicle, and drive home. However, once again, the vehicle was unresponsive. Accessing the car required removing the cap from the door handle and manually inserting the key, a process that took approximately ten minutes, which was particularly inconvenient and concerning in an airport parking lot. This situation was even more challenging considering I am a [XXX] woman of smaller stature attempting to resolve this issue alone at night. I believe this poses a serious safety concern for all owners under similar circumstances. Following the incident last Fall, I brought my Sonata Hybrid to Key Hyundai in Jacksonville. I was informed that this is a known issue for which there is a recall; however, my vehicle model year is not included in the affected range. It was suggested that I would need to manage this problem independently. I believe this recurring issue represents a known vulnerability that could potentially expose Hyundai and its dealerships to liability should an owner suffer harm while addressing this malfunction.

  Reported this previously, but more information was gathered, thanks to collision mechanic who guessed immediately when he heard 2023 hybrid Sonata - he said "they're notorious for it." Was at a stand still in a parking space/lot I know well. Cautious driver, watch my speed, very aware of other drivers, quick reaction time. Incident mid day, no pedestrians, distractions, no moving traffic. Vehicle doors shut, seat belt on. Not on incline. Pulled into parking spot I use weekly, spot has parking curb. Was at a full stop. Realized I had not pulled into the spot quite far enough, and attempted to inch vehicle forward. (Do not recall any warning lights, but this car usually alerts at literally anything - even shadows.) Very lightly applied gas to inch forward, slowly. Felt slight "scrape" of undercarriage on the parking curb. Put car in reverse, lightly applied gas to inch back. Car did not rev, no screeching tires, it was at a standstill previously. Was in Eco mode. All seemed normal, until vehicle suddenly launched UP the parking curb, full force, and into a building pillar directly ahead. The car never moves with that much force, I'm not a pedal-to-the metal driver. Eco mode on. No airbag deployment, injuries, etc. Sheriff took report for the building, simple incident. I couldn't make sense of it. I know how overly cautious I am while parking, what I do, and don't do. Took responsibility, but was still analyzing a week later, and explained what I remembered to the mechanic. He guessed right away. Said Sonatas were notorious for it. He said they're known for randomly applying the ebrake unexpectedly - and also randomly releasing the ebrake - and aggressively (and silently) switching from electric to gas when met with resistance, aka the parking curb. Insurance totalled the car. 2.5 years old, 17k miles. This was my 3rd Hyundai in 20 years, others were great. Discovered 40,000 Elantra hybrids, same year as my Sonata, were recalled due to "unintended acceleration."

On February 14th it sport Hyundais negligence was the direct cause of an auto accident were the car was unable to move out the way because of lack of power /limp mode. I begged them in the final days of me having the car to fix it and saying I didn’t feel safe and they wouldn’t without an extensive amount of money I could not provide . I’m currently filing a claim with Hyundai consumer affairs and the dca in Newark and also my senators office and I have a lawyer also who might help I wish to report this to the NHTSA.

  Vehicle WITHOUT WARNING will start to jerk then go into “limp” mode. Pressing on gas pedal makes the revving noise but with not physical movement made. This has happened on MULTIPLE occasions (13 times in 4 months) including in the snow and on the interstate while driving at 70mph where no shoulder is available to pull over. Car was taken to dealership 3 different times with no actual diagnosis, tests were ran all 3 times with nothing. Eventually the 3rd time at the dealership I was told the transmission was being replaced although they were not sure what actually caused the issue (this is written in the service report by the rep/mechanic). CAR REMAINS UNSAFE AND UNRELIABLE. Livelihood of myself, family and other drivers is at risk EVERYTIME I put the car in drive due to this mechanical issue. NO WARNINGS NO POWER NO FIX.

  I am filing this complaint regarding Recall 25V-796 (Hyundai Recall 286). On November 27th, while driving, my vehicle made a loud popping noise twice and then began sounding muffled. About a week later, while on a long-distance drive, I attempted to refuel and the gas would not go into the tank. At another gas station I was able to fuel it, but afterward the vehicle began rapidly leaking fuel while I was driving. The fuel gauge was also malfunctioning. It showed 53 miles remaining and then suddenly jumped to 200 miles. It was not accurately reflecting the fuel level. When I stopped again for gas, the same muffled noise occurred and the fuel level rapidly dropped again. Due to safety concerns, I took the vehicle directly to the dealership.I dropped the vehicle off on December 6th and it has remained at the dealership ever since. The vehicle is currently sitting in their lot with no remedy available. I am still making monthly payments on a vehicle I cannot use. Although Hyundai provided a rental vehicle, it has now been over three months of inconvenience, including having to exchange rental vehicles for service. This has caused disruption to my daily life and financial strain. Hyundai has offered to pay off my loan and provide 8% toward the purchase of another vehicle. However, I am a single mother who is currently rebuilding financially after losing my job in prior years, and my credit score has been affected. I do not believe I should be pressured into purchasing another vehicle due to an unresolved manufacturer safety defect. I also attempted to seek guidance regarding Florida Lemon Law, but was informed that I may not qualify because the vehicle was purchased in April 2023 and the issue occurred after the two-year period. However, this is a manufacturer recall involving the fuel system, and I believe it is unfair that I am left financially responsible for a vehicle with a serious safety defect and no available remedy. I am requesting investigation

Put in reverse to back away and car stayed still...then I tapped the gas again to back up and insted vehicle plowed forward.instead.of reverse ...went over the parking block and hit concrete beam in front, when the car should have backed up in reverse. I'm a person who drives speeed limits, and ulta careful when i drive, and parked at this place/spot for years. This has never happened not sure why it did. No injuries or other people involved thank god, but scared the heck out of me. Wracking my brain, my recalls and software and service appts are up ro date.Nothing out of ordinary that day. I'm confused and shaken, why the first lurch forward and why did going in reverse move it forward? ugh. It drove home fine. Commute to work daily for years, no issues. All I can guess is gear didn't click to reverse and was somehow in drive? Ive been going over the possibilities in my head for human error but they dont make sense - again I've been driving for 40 years. If it happens to other models, would love to know! Car will go to repair tomorrow as "my fault" via insurance, hoping they can see more if any error codes, to at least say if Reverse didn't engage or something else happened. May have been human error but it's so out of the ordinary for me. Thanks!

  My Hyundai Sonata 2023 is experiencing two recall codes. The first one was 9b1 which was resolved, but the other one is indefinite which is 286. I dropped my car off on December 4 of 2025 and a month later Hyundai’s corporate team reached out to discuss the state of my car. They asked me for things such as the payoff balance of what I owe through CarMax who I’m financing the car from, they asked me the mileage on the car, the registration and the lien. They then told me they would provide me with an update by certain dates it’s been over two months and I haven’t received any updates. The car shop called me to come pick up my car because one of the issues was resolved, but after reviewing the recall code 286 and seeing that there is very much so a safety risk when driving the car, I ultimately chose to leave the car with Hyundai. Hyundai has been unsuccessful with providing me with the solution. I’ve waited two months almost 3 months and I believe that this vehicle is a lemon and I need a solution. Hyundai took back the loaner, I have nothing now and they keep telling me they’re going to follow up, but have not followed up with anything I need help. I don’t want to risk my life, driving the car and being paranoid that it could catch on fire and harm me or other people driving in it please help.

  At least 8 times when driving the car the transmission switches from the drive “d” position to the park “p” position and I have to cut off the car and then restart. It is very dangerous as I can be rear ended which can result in personal injury as well as an insurance claim. I’ll put the last date it occurred but started experiencing soon after I bought car.

  On January 6, 2026, during my morning commute in heavy traffic, my 2023 Hyundai Sonata engine unexpectedly turned off, causing a sudden loss of power. This created an extremely dangerous situation, and I came very close to being involved in a major collision. While I was fortunate to avoid a crash, the incident posed a direct threat to my safety and life because of the dense surrounding traffic.

  Hello Sir/Madam, While driving on Interstate I-75 at approximately 70 mph, the yellow check engine warning light suddenly illuminated. Immediately afterward, the vehicle began to shake violently, lose engine power, and run extremely rough. The vehicle experienced a sudden loss of power, and pressing the accelerator pedal did not result in normal response or acceleration. The throttle input was significantly reduced, making it difficult to maintain speed and safely control the vehicle. At highway speed and in heavy highway traffic, if we had not been able to safely exit the roadway, this loss of control could have put not only the occupants of this vehicle but also other drivers at serious risk. Fortunately, we were already in the exit lane, and a McDonald’s parking lot was located immediately off the exit. This allowed us to leave the highway quickly. Otherwise, this situation could have been extremely dangerous in active, heavy highway traffic. As the vehicle continued to shake, a strong smell of gasoline and a burning odor entered the cabin, raising concerns about a possible fire hazard. We safely stopped the vehicle in the McDonald’s parking lot and then shut the engine off due to the severity of the symptoms. After shutting the vehicle off, we attempted to restart it, but the engine would not start. The vehicle had to be towed to a Hyundai service center for inspection. The Hyundai service center later confirmed that the failure was caused by a faulty fuel injector, and they have changed all 4 injectors as I attached receipt from Hyundai This failure created a serious safety risk due to sudden loss of engine power, reduced accelerator response, severe shaking at highway speed, and fuel and burning odors inside the cabin.

  My car was having an issue where it was losing all the coolant, causing my engine to overheat twice while driving down the highway. Unfortunately I couldn't find a leak anywhere and there was no fluid leaking in my garage. I lost an entire reservoir of coolant overnight. After taking my car to the dealership to get repaired, I was told that it was leaking my coolant into the exhaust system and burning it up. I was also told "it was a know issue, they had a bulletin from Hyundai on how to fix the problem, and Hyundai completely redesigned the part to stop the leak and it had to be special ordered." I was without my car for a week and left with a $1300 bill as apparently it was not covered by my warranty. I have no idea how a known issue is happening so frequently that requires a nationwide bulletin and a part redesign, yet somehow is recalled. Especially considering it left me stranded on the side on the side of the highway in Indiana during a snow storm but someone seriously needs to investigate it.
