The windshield wipers will only go up once they have fully gone down all the way. Therefore, when snow (or something else) gets stuck below the windshield wipers while they are in use, they cannot go all the way down, and they will therefore not go back up again. The wipers become inoperable while trying to complete their cycle, and stay stuck in place creating extremely unsafe conditions. This
... incident occurred numerous times while in the snow, where a large chunk of snow or ice prevented the wipers from going all the way down, and the wipers would not work to remove additional falling snow until I pulled over and cleared the area below the wipers. I contacted HyundaiUSA and they said I had to go to dealer to address this issue, but the problem is not a manufacturing problem or broken part with my car, it is a design flaw that significantly impacts safety.Read more

We bought two of these car seats and the base on account we liked the feature that the car seat can rotate in the base... This car seat is UNUSUALLY UPRIGHT on its own and I believe the base insert makes it worse. I am a first time mom and I didn't realize how bad the ergonomics of this car seat are until recently, but my baby absolutely HATES the car now because she associates it with how uncomfo

Incident date: Aug 13, 2026
The vehicle suffered an abrupt, internal engine seizure while operating in active traffic at highway speeds. This sudden loss of power created an immediate crash hazard, as the vehicle decelerated rapidly in the travel lane, narrowly avoiding a rear-end collision and putting my family and other motorists at extreme risk. The vehicle was towed immediately to an authorized Hyundai dealership serv
... ice center where it is currently awaiting the physical recall inspection. Prior to the complete engine failure, there were no warning lights, abnormal gauge readings, dashboard messages, or noticeable performance symptoms. The engine seized completely without warning. The vehicle has an open, uncompleted Federal Safety Recall 162 (NHTSA Campaign Number: 16V729000) for this exact engine manufacturing defect and bearing failure.Read more

Component Failure I was driving on [XXX] in [XXX] at 70 miles per hour. My red oil indicator light came on, and within seconds the vehicle suffered a catastrophic power loss. I had zero control of the propulsion. I was in the right lane and managed to steer to the shoulder. I contacted Hyundai Roadside assistance/Hyundai care. They sent a wrecker in about an 45-1 hour as I sat on the side of the
... highway. I was then put into a wrecker and my car was loaded on a flatbed truck and we then took a 45 minute drive to [XXX] to Weisner Hyundai where the vehicle was left for diagnostic testing. Safety My safety was undeniably at risk due to going the speed limit to zero in seconds. It put me in harms was due to other drivers on the road not expecting a car to stop at those speeds, unable to react in time without causing a collision which could have resulted in significant bodily injury or death for myself, my passenger and possible many others on the road that were around me. I was afraid, not sure what had happened, very distraught and traumatized. I fear for my safety in this vehicle. Service Center The car was taken to Weisner Hyundai at this time they have been unable to replicate or discover any code. They have seen the oil light come on. They have had my vehicle since XXX until today XXX when they were going to send it to [XXX] Hyundai where I purchased the vehicle. Inspections I am not sure about who all has looked at it within the dealership. Warnings The only warning I had was a red oil lamp that appeared on the dash seconds before the catastrophic loss of power. Special Note, I just found out that my vehicle originally had repairs done as it came from transport to the engine/oil components which were not disclosed to me by the dealership prior to me purchasing the vehicle "new" at full price. The dealership had knowledge that the vehicle already had issues that cause the malfunction and sold it knowing the dangers.

System/Component Failed & Inspection: The vehicle suffers from recurring failures across the engine, powertrain, electronic throttle control, and exhaust gas recirculation (EGR) control systems (DTCs P0524, P0642, P2118, P022100). The vehicle is fully available for inspection upon request. Safety Risk: While driving, the vehicle suffered a complete, sudden loss of motive power on an active highwa
... y entrance ramp. The engine stalled in moving traffic with zero throttle response, creating an immediate collision hazard before requiring a tow. Confirmation by Dealer: Technicians formally confirmed these defect patterns. In May 2026, diagnostics logged major engine and emission/EGR control codes, but corporate refused goodwill repair. In August 2026, the highway stall recurred. Diagnostics confirmed active low oil pressure and throttle failure codes, which the dealer resolved by applying 4 factory ECU software updates under TSB 25-01-010H. Service personnel explicitly confirmed these engine control issues are manufacturing defects, not wear-and-tear or mileage-related. Inspections: Inspected, diagnosed, and serviced by authorized dealership service department technicians during both the May and August 2026 failure events. Warning Symptoms & History: Engine issues began at 341 miles when purchased new (settled). In May 2026, check engine lights returned with diagnostic codes for engine and EGR/emissions systems. In August 2026, total power loss occurred, preceded by check engine, forward collision camera, and radar sensor warnings.Read more

TAKE A BREAK" - the feature prompts the driver to “Take a Break” with that text and a‘Coffee Cup” logo after a certain period of continuous driving. There are instances when turning it off is necessary and Hyundai has removed that option - high distracting false alarm rate. The alert, visual and auditory are intrusive, unnecessary, demonstrate a high false alarm rate leading to frustration
... and distraction. While designed as a safety feature, it has the opposite effect. The system inaccurately interprets the driver’s behavior as signs of fatigue with alerts popping up at an alarming rate. Perfectly normal and safe driving behaviors see the alert popping up again and again. Further there are environmental interferences - bright sunlight, reflections off glasses, bumpy roads requiring frequent corrections - system interprets these as driver inattention and cannot tell the difference between drowsy driving and navigating a poorly maintained highway. New Hyundai models do not allow the driver to disable the Take a Break alert. “You’re cruising down the highway, minding your own business, alert and focused, when your Hyundai flashes a coffee cup icon and tells you to take a break. Again - this for the third or fourth time in 20 minutes. You’re not tired, not swerving, and frankly, you’re getting annoyed”. The system is disruptive and unsafe as it disrupts the driver activating when the system detects inattentive driving, suggesting breaks even if the driver does not feel fatigued. The alert can illuminate even during short drives of less than 30 minutes. The alert can occur extremely frequently, especially during long drives, which is extremely annoying. The warning can appear shortly after starting a trip and may repeat every few minutes, which is extremely frustrating. It is far more disruptive than safe and helpful.Read more

Incident date: Aug 4, 2026
I own a 2022 Hyundai Elantra N Line. The HVAC system began malfunctioning when the center/forward-facing dashboard vents stopped producing airflow, while the side vents continued to work. Changing the HVAC mode does not properly redirect airflow to the center vents as intended. The vehicle was inspected and diagnosed, and I was informed that the ventilator lever/mode mechanism is broken or not fu
... nctioning properly. This appears consistent with a known issue described in Hyundai Technical Service Bulletin 25-HA-001H/26-HA-001H concerning the ventilator lever and loss of airflow from the forward-facing center vents. This failure affects my ability to properly control where air is directed inside the vehicle, including directing airflow toward the windshield for defrosting/defogging. This could potentially reduce visibility in conditions where windshield defrosting is necessary and therefore create a safety concern. The problem has been confirmed through a vehicle diagnostic inspection. The vehicle/component is available for inspection upon request. I have also found other Hyundai Elantra owners reporting similar loss of center-vent airflow and HVAC mode-control problems. The issue occurred without a collision or other known event that would have caused the component to fail. The repair is also unusually labor-intensive because the failed ventilator lever is located behind the dashboard and requires extensive disassembly just to access the component. I was informed that the repair would require at least 14 hours of labor, resulting in an extremely high repair cost for what is essentially a small mechanical component. The amount of labor required to reach and replace the lever makes the repair disproportionately expensive. Additionally, I have encountered multiple other Hyundai Elantra owners reporting the same or very similar symptoms, including loss of airflow from the center/forward-facing vents while the side vents continue to function. Suggests occurring issues.Read more

The vehicle's OEM wiring harness caught fire during standard operation. We had just started our drive connected to a trailer and break controller that functioned flawlessly for a year with a different vehicle prior to this incident. The trailer is a 2025 and the brake controller was new at the time of purchasing the trailer in February 2025. the only thing that prevented further damage was my hus
... band calling to say something was smoking and I needed to stop the car. I was driving to pickup my husband and children from the campground bath house to drive home. Yes, it is available for inspection. The safety of myself and any passengers was put at risk due to the electrical fire and all extenuating risks associated with that. The problem has not been reproduced by the manufacturer that I am aware of. The tech at the dealership verbally confirmed that the part in question was the cause of the fire and that the new (post repair) part did not have a secure 7way plug attachment to the break controller which was also brand new since the original was damaged during the incident. The components have been inspected by the dealership. There were no lights prior to the failure and there were no lights after the failure until the new temporary harness was installed in Slade KY prior to receiving and installing the new (same) OEM part once we returned home.Read more

I am reporting serious repeated safety failures with my 2026 Hyundai IONIQ 9 involving unintended emergency braking and sudden loss of propulsion. While traveling approximately 70–75 mph northbound on I-15, the vehicle suddenly displayed an emergency braking warning and aggressively slowed despite no apparent obstacle or traffic condition requiring emergency braking. Before I could regain contro
... l, the vehicle came to a complete stop in active freeway traffic with vehicles around and behind me, creating an extreme risk of a high-speed rear-end collision. Something similar has happened on two other occasions. On a separate occasion while traveling on I-40, the vehicle again unexpectedly initiated emergency braking. I was able to disengage adaptive cruise control and regain control before the vehicle came to a complete stop. The vehicle has also experienced two separate loss-of-propulsion incidents. During one, the vehicle suddenly limited its maximum speed to approximately 22 mph and would not accelerate normally for approximately four miles before returning to normal operation without explanation. During another incident, the vehicle suddenly would not exceed approximately 40 mph. I safely pulled over, but once stopped the vehicle would not accelerate from 0 mph, leaving me unable to re-enter traffic. Normal operation returned only after shutting the vehicle off and restarting it. The Hyundai dealership has inspected the vehicle 3 times and has had it for more than 3 weeks, but states it cannot replicate the conditions. These failures are intermittent but have occurred repeatedly and involve critical braking and propulsion systems. I am concerned another event could cause serious injury or death, particularly if the vehicle brakes unexpectedly at freeway speed or loses propulsion while merging or crossing traffic. I am requesting NHTSA investigate this potential safety defect.Read more

The contact owns a 2011 Hyundai Sonata Hybrid. The contact stated that while driving at an undisclosed speed, there was an abnormally loud sound coming from the vehicle. The contact turned off the vehicle, and while inspecting the vehicle, the contact became aware that there was a puddle of oil on the ground underneath the vehicle. No warning lights were illuminated. The vehicle was taken to a nea

The contact was informed of Technical Service Bulletin: 22-EM-006H-2. The contact was advised to tow the vehicle to a Hyundai dealer for assistance. The vehicle was towed to an alternate dealer where the failure was confirmed. The vehicle was not repaired. The manufacturer was made aware of the failure, and a case was filed. In addition, the contact was informed that the repair was not covered under warranty. The contact was informed that the repair was denied because of the previous owner's negligence with maintenance of the vehicle. The failure mileage was approximately 120,744.Read more

In the past two weeks, our 2021 Hyundai Palisade has shut off completely when driving. It has around 110,000 miles on it and was just purchased used (second owner) three months ago. At that time, the dealership had to fix a leak in the engine and did a complete oil change. Based on internet searches, we just checked the oil dipstick and it is COMPLETELY empty. We have NOT driven more than 3,000 mi
... les since purchasing the vehicle and there is absolutely no oil left. Based on searches, it appears this is a fairly common, known issue and nothing is being done. It is incredibly dangerous that the car shut down while driving (on the highway, in the middle of a right-hand turn). Every single warning light lit up at once then the car completely shut off within a matter of seconds. Thankfully my husband was able to get to the side of the road and no accidents occurred, but this is terrifying and completely unacceptable. The car is going to be towed to the dealership to check for excessive oil consumption, but again, based on research, it appears that this is a known issue but Hyundai says it is "within acceptable limits."

The engine mounts on this vehicle failed. Dealership and many others online have stated that this seems to be a reoccurring issue with the 2021-2023 generation of Hyundai elantras. The vibrations of these failed motor mounts become so severe that they can dislodge the brakes making it very unsafe to drive. Hyundai should be doing a recall for this to avoid safety issues for their customers

The fuel range calculation is often very wrong in our plug in hybrid. This issue has been brought to the attention of the manufacturer and dealer with no results but pointing at the other organizations. With a full fuel tank the gasoline range should be about 387 miles. Often the computer will show 610 miles but sometimes has other ranges but has never been correct after the first fill up. Whi
... le this normally isn't a big problem, there is a danger for some people. Say you see a sign on a curvy mountain road with no shoulders showing the next fuel is in 100 miles. If the car computer says you have a range of 150 miles, you would think you can easily make it to the next gas station. However, because of the computer error, you really only have a range of 95 miles. It is probable that you would run out of fuel, losing power steering and power brakes. Additionally you could end up stopped blocking the lane and causing a collision. This has been occurring for three years, ever since our first fill up of the gas tank.Read more

I bought my 2012 Hyundai Tucson from a used car dealership back in November of 2024 . When I bought the vehicle it only had 55,000 miles on it and came with a 2 year unlimited mile warranty on the drive train and a full Carfax history in which everything came back clean , regular oil changes with synthetic oil every 4,000 miles and for my warranty through the used car dealership requirements I hav
... e continued to honor the every 4,000 mile oil change with synthetic oil every time . I have my Carfax that shows that my vehicle was brought to a certified Hyundai dealership back in 2019 for maintenance and the dealership never applied the required KSDS software update to extend my warranty. Flash forward to 8/06/2026 my vehicle with only 94,000 miles on it is sitting at a Hyundai dealership with the engine blown . I filed a claim with Hyundai and of course they denied it . I filed a complaint with corporate because it was at a certified Hyundai dealership back in 2019 they have had the updated KSDS software available at the time knew that it was a requirement for the extended warranty and didn't add the software update to my vehicle. I have asked for a good faith gesture and was also denied . I'm on a fixed income with a disabled husband and a disabled son . I still owe a considerable amount on the vehicle since I've only owned it for 1 year 7 months . The used car dealership I bought it from will only cover up to $2,900.00 of the repairs and the new engine is costing me $7,601.01 . Leaving me with a remaining bill of $4,701.01 . While that's pennies to them to me that's 4 months rent and my family not eating for 4 months . . I even tried to work with them to split the cost and again was denied . They know their 2.4 theta engine is inferior and was court ordered to extend their warranty. I was informed when I brought it to the dealership that is fixing which is also a certified Hyundai dealership that it has 4 open recalls attached to my vehicle that needed to be fixedRead more

FORMAL SAFETY COMPLAINT – REPEATED SIDEWALL BUBBLES IN PIRELLI SCORPION MS TIRES Vehicle: 2026 Hyundai Santa Fe Calligraphy Tires: Pirelli Scorpion MS Size: 255/45 R20 I am submitting this complaint because I am extremely concerned about a recurring and potentially dangerous tire problem involving my nearly new 2026 Hyundai Santa Fe Calligraphy. The vehicle is equipped with Pirelli
... Scorpion MS 255/45 R20 tires. Within only four months of ownership, the first tire developed a significant sidewall bubble on the right rear tire. The vehicle had approximately 816 miles at that time. What is particularly troubling is what the dealer told me when addressing that first tire: the first replacement tire they received also had a sidewall bubble, and the dealer had to obtain another tire. In other words, a replacement tire supplied for my vehicle reportedly arrived with the same type of defect before it could even be installed. At approximately 10 months and 7,425 miles, another tire — the left rear tire — developed a sidewall bubble the same as the prior tire In total, two tires have developed sidewall bubbles during the first ten months of ownership of this car plus the ‘replacement’ tire. There have been no known impacts, pothole strikes, collisions, or other events that would explain these repeated sidewall failures. There have been no blowouts, and fortunately no one has been injured and the vehicle has sustained no damage. However, I consider myself fortunate that these problems have been discovered before a catastrophic failure occurred. The most recent tire was replaced by Oxendale Hyundai in Flagstaff. The dealer submitted the tire to Pirelli for warranty consideration and mentioned the bubbles in the other tires. Pirelli’s response was simply: “REJECTED.” There was no explanation, no apparent investigation, no request for additional information, and no discussion of the fact that multiple tires on the same nearly new vehicleRead more

The AC/heating blower motor circuit on my 2020 Hyundai Sonata failed intermittently due to extreme electrical resistance overheating and melting the terminal pins inside the engine fuse box. I took it to the dealership and they inspected it said it was out of warranty but it needed part number 18980-09910-FFF and wiring kit 91300L1000-FF to repair at a cost of 780.00 including parts, tax, and labo
... r. This matches the severe design defect acknowledged in Hyundai TSB #25-EE-002H or alternative TSB-24-EEOO-1H. I filed case number 43138757 with Hyundai corporate. For now this just affects my air conditioning. However, the root failure is a known design defect that presents a severe vehicle fire hazard and potential loss of windshield defrosting capability, lights, etc. if the whole electrical system should fail. As you should know the engine bay fuse box (which currently has melted parts) is the "brain" for the car's electrical distribution. It doesn't just power my AC fan; it holds the fuses and relays for the cars fuel pump, engine control module (ECM), headlights, and electronic power steering. If left unfixed and over time as the plastic melts, copper wires will cross and touch each other, causing a massive short circuit. My engine could suddenly cut out and stall while I am traveling at 70 mph on the highway, instantly killing my power steering and power brakes and putting me in extreme danger. Again not to mention the fire hazard this situation is likely to cause. This should be addressed via a mandatory safety recall, so that I don’t have to pay for a known engineering design defect and in case the TBS bulletin fails or further unknown damage has already occurred.Read more

Multiple occasions of the ADAS lane centering system operating unsafely. The worst one was on a gentle left-hand curve on a concrete surfaced bridge at night. The system allowed the vehicle to slowly drift to the outside of the lane. When it was fairly close to the white line, it jerked the wheel back to the left and then released the steering to my control while pointed hard into the oncoming
... lane. It will do similarly during the day when approaching a center turn lane on the highway. Sometimes it will decide that it should be in the turn lane, will make a rapid input, and then return control to me, now pointed at the oncoming lane. When the vehicle returns control to me, it indicates it by making the steering wheel and lines in the HUD grey, no chime, no warning icon, just green to grey and release the wheel in whatever direction it's pointing. It also sometimes slows drastically for vehicles that have exited the highway when on cruise control or applies hard braking for vehicles in the other lane while in a curve on a hill. There are no lights or malfunction warnings and the vehicle self-diagnostic says everything is operating correctly.Read more
