ENGINE
Me along with thousands of others are experiencing the “excessive oil consumption” issue. Hyundai is doing nothing except making us pay tons of money for testing when they already know what the issue is and is refusing to do anything. Enough is enough. I can’t afford a new car nor should I be forced into buying one. The dealerships have been instructed by Hyundai USA not to admit negligence or helping g the car owners.

FUEL/PROPULSION SYSTEM
(August 29th) My girlfriend and I were driving in my 2020 Sonata, when the check engine light turned on and my gas gauge dropped from being full to then only half way. About an hour later, driving back home we heard a loud pop as if something exploded. Next day, I took my car to the Autonation Hyundai dealership and after taking a look at my car they quoted me about $6,000 to get my fuel tank and charcoal canister replaced. Our safety was put at risk due to the fact that had the damage been any worse, it could have caused the car to possibly explode or give out while driving on the highway, and in turn would put many more lives at risk.

ENGINE, UNKNOWN OR OTHER
This is the seventh occurrence of complete loss of power while driving on the interstate. The hybrid system warning activated, followed by the engine shutting down, and all dashboard lights illuminated with alerts indicating "Shut Off Engine/HEV." An 18 wheeler was pulling out from the shoulder as I was losing power and barely missed getting crushed. The former problems have all been at interstate speeds with similar accident avoided. The service history clearly demonstrates that Hyundai has repeatedly attempted to address this issue by replacing numerous critical components, including the engine, transmission, knock sensor, battery (three times), integrated brake actuation system, and smart cruise control, among others. Despite these extensive repairs, the problem persists. On this latest occasion, less than 4,000 miles and four months since the last major incident, the dealership has proposed replacing the intake manifold, EGR valve, HSG belt, and spark plugs. The belt was changed less than 20K miles ago. and I believe the spark plugs were as well. Each time my vehicle experiences this issue, it is out of commission for weeks or even months at a time, causing significant inconvenience and raising serious safety concerns. I no longer trust this vehicle and I don't believe the many recalls have successfully addressed the root cause of issues with the 2017 Hybrids.

ENGINE AND ENGINE COOLING
The contact owns a 2015 Hyundai Sonata. The contact stated that the check engine warning light illuminated after having the oil changed. The vehicle was taken to a certified mechanic and the contact was informed there was no oil in the engine. The contact had paid for a better grade of oil in the vehicle. The mechanic inspected the engine and could not find any failure. After having the oil changed the check engine warning light was illuminated. The contact had taken the vehicle to another mechanic approximately 3 weeks later who was unable to find any failure with the engine. The mechanic had reset the sensor. While driving approximately 5 MPH, the check engine light illuminated. The vehicle was returned to the mechanic who reset the sensor again. After having the vehicle serviced, while driving approximately 50 MPH, the warning light illuminated again, and the vehicle stalled. The vehicle was towed to the mechanic and the contact was informed that the O2 sensor had failed causing the engine to seize. The vehicle had not been repaired. The dealer had been contacted, and the contact was informed that the vehicle had a Salvaged Title and there would be no assistance provided. The manufacturer was not made aware of the failure. The failure mileage was 97,000.

STRUCTURE:BODY
My passenger side rear door will not open from the outside or the inside. You pull the handle on the outside and nothing happens. You push the door from the inside and nothing even budges (the door lock still works not that there's a use for it right now). This seems to me to be a safety risk for anyone that has to sit in the backseat behind the front passenger seat. If there were an emergency, they would not be able to open the door to get out. I have Googled this and it seems to happen quite frequently in Hyundai cars. It's the door actuator. If this happens a lot, then I think Hyundai needs to take a deeper look into their door actuators. Thank goodness I do not have kids in a car seat because I would be unable to get them in or out on that side of the car. I've never had this happen on any of the Toyotas I've owned.

I have been driving at night about 3 times now and my headlights have gone off on their own and come back on after about 10 seconds. This has happened on countless other Hyundai drivers vehicles and needs to be investigated.

My vehicle has an oil consumption problem despite the fact that my car has been excluded from the class action lawsuit. I’ve had it in the shop and they have confirmed the oil consumption issues. There are countless other vehicles excluded from the class action lawsuit that have the same theta engine as the other vehicles that were included in the lawsuit. This needs to be investigated. I still owe over 6k on my car and it’s one trip away from being completely undriveable

FUEL/PROPULSION SYSTEM, POWER TRAIN, SEATS
Hello, I have Hyundai Sonata 2023. The fuel tank of this car is expanded on [XXX]. I have never heard about this issue to any cars. I took my car to dealership they said they don’t know why this happened and they said they cannot fix it, my car at the dealership more than a month. I have created a case with Hyundai corporate office in CA, it’s been a month since this case was created and I could reach out to my case manager only twice for this period of time. They are keep saying they are working on it, but no results they don’t even look at my car. Today I barely could reach my case manager and she told me that this is not under warranty and I will need to fix it out of my pocket. When I bring the car to the dealership they told me this not under warranty since warranty was up to 60k miles, I have 90k I asked them to fix it and I will pay but they said they don’t know how to fix it. Today I have researched and found that this issue is really common among Kia K5 and Hyundai Sonata’s 2021 2024, I will provide a link here: [XXX] Please check this link and you can see that most of the cars fuel tanks are expanded and back seats popped up. I have same exact problem. Kia asked drivers to inspect the cars with this issue and they said they will fix it for free since this is fuel tank defect. But what should I do with my Hyundai Sonata. I have same exact issue as you see at the link I have provided. I had powertrain DTC PO451 since march of this year dealership said just check if gas cap is on properly, but this caused this issue I see Hyundai will not help me it will almost 2 month I don’t have my car and I am still paying for it, please let me know what I can do Thank you!

ELECTRICAL SYSTEM, VISIBILITY/WIPER
Improperly seated strip fuse High Resistance Connection on the IG-2 40amp blower motor fuse receptacle causing melting of plastic fuse box components and ultimately failure of blower motor circuit and potentially loss of other circuits. Loss of blower motor leads to loss of cabin HVAC as well as loss of front windshield defrost ability during adverse driving conditions. Not only does this pose a potential electrical fire hazard, but a safety hazard due to inability to clear windshield from loss of defrost feature. Brief research finds this to be a very common problem with these vehicles. Manufacturer's recommendation is complete replacement of engine bay wiring harness. Problem begins as intermittent, but leads to total circuit failure over time if not identified.

ENGINE
The contact's husband owns a 2015 Hyundai Sonata. The contact stated while the vehicle was at an independent mechanic for an oil change, the contact was informed that the vehicle was experiencing excessive oil consumption and that it was a known failure. Additionally, the contact stated while driving 73-74 MPH, the vehicle shuddered and stalled. The contact was able to pull to the side of the road. The vehicle failed to restart and was towed to an independent mechanic, where it was diagnosed that the rod bearing had caused engine failure. The dealer determined that the engine needed to be replaced. The mechanic informed the contact the failure was due to a factory defect and would reoccur even after the engine replacement. The vehicle was taken to the dealer, where the same assessment was made. The dealer filed a claim with the manufacturer and sent a diagnostic report with pictures of the failure; however, the manufacturer denied the claim several times. The contact stated that the engine was previously replaced. The manufacturer was notified of the failure. The failure mileage was approximately 152,550.

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
I have had this car for 2 years (13K miles)....intermittently the car stops short when backing up. This has happened at least 15-20 times, backing out of my garage. It also happened twice backing out of a parking space. The most recent incident was driving on the hwy at 70MPH and the emergency brake warning light came on causing the car to swerve, stop for a few seconds. Needless to say this was very scary. I am attaching a link with the same or similar complaints: [XXX] I have been in touch with Corporate. The car is currently at the dealer ship and has been for 2 weeks. They are trying to duplicate the problem, but it is so intermittent, I doubt they will find anything. I was told they have to keep it for 30 days, then....I don't know what the next step is. I love this car, but no longer feel safe in it. Please advise how you can help. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ENGINE
I had the engine replaced in Feb of 2024 which was covered by the engine replacement recall. In May of 2024 I started having issues with my check engine light flashing on then off. The engine will lose power briefly during this time and the engine shakes. It feels like you are going to lose control of the vehicle when this happens. This has happened approximately 3 times at freeway speeds and a total of approximately 15 times total. I have taken it to the dealership 3 times for this issue. They made us pay for spark plugs that were fine when the engine was replaced (3800 miles was driven between the engine replacement and this issue starting). The dealership has now had the vehicle since the middle of May said they can’t recreate the problem but are saying it is a fuel pump. This was also fine when the checked it when the engine was replaced.
