ENGINE, VEHICLE SPEED CONTROL, UNKNOWN OR OTHER
My car experiences issues around acceleration. It often feels like it gets “stuck” or hesitates when I try to accelerate from a stop (ex. a stoplight) or low speed or when I try to merge onto the highway. At times I have not been able to merge onto the highway at a safe speed because my acceleration gets stuck/lags at a low mph (ex. 35 mph onto a 70 mph highway). My car also excessively consumes oil. I started noticing the excessive oil consumption around 115K miles. My oil lamp does not illuminate when low on oil in nearly all cases I have been low on oil. It has only come on once (did not remain on) and oil was not present on the dipstick. I am 687 miles into my current 1,000-mile oil consumption test and have had to top off my oil twice. I started the test because my oil light flashed and oil was not present on the dipstick. The engine light came on 312 miles into the consumption test. I got a diagnostic code from AutoZone and relayed the diagnostic code to the dealership. The dealership said the code was related to low oil and to fill up with oil and bring the car to the dealership. I filled it with oil and drove the car to Luke’s Auto for an independent inspection. Their inspection found that the check engine light was from a failed e-cvvt and additional wear was present. I asked if this could be caused by oil consumption issues and they confirmed the possibility. Just over 300 miles from that incident, I checked my oil and it was once again low. I am deeply concerned about the safety of my vehicle due to it's stalling and indicators of potentially seizing. I have had near collisions on the highway due to my vehicle getting "stuck" while accelerating and unable to enter the highway at a safe speed. I am concerned about the consequences of lack of oil and failure of my oil lamp to illuminate to indicate no oil such as my engine seizing or catching fire. I have reported these concerns to the dealership since 1/2/23 and have reported my concerns to HMA.

FUEL/PROPULSION SYSTEM
While driving on the country side, my car engine stopped providing power to the car and started making some noise. The engine rpm would fluctuate and increase due to downshifting but there was no power. Luckily, the car had some speed around 50 mph, the road was slightly downhill and nobody was behind, managed to coast to a gas station half a mile away. The engine shut itself off after the car stopped. I was able to restart the car but it would shut itself off within 2 seconds of restart. Car was towed to the dealership and I was told that it had a faulty injector. The injector was replaced a week later and I received my car back later.

ENGINE
Bought a car. In couple days check engine light came on, it was blinking and car was put on limp mode, rpm between 1800-2000, speed 60-62 mph. Went to dealership they did full diagnostics, told that they are going to submit to Hyundai to replace engine at their cost. Hyundai came back that they want to replace knock sensor and then see what’s gonna happen. I replaced and was told that i have to pay even though there is a recall on Knock sensors. They replaced the sensor which was over 600$. And the problem came back in less than 36 hours. Now the vehichle is back again at the dealership and they gonna do diagnostics again. Which is ~200$. I need to help this resolved as i’m only being ripped off with no solution. The vin says it doesn’t have any recalls, but vehichle is experiencing exactly what’s on recall. The vehicle has been in the shops for a month now. Thank you

ENGINE, ELECTRICAL SYSTEM
2021 Hyundai Sonata 59,850 miles RPM jumps to around 1,300 at zero miles on occasion. If I am stopped, at a red light or behind other stopped autos, the vehicle jumps forward when I take my foot off the brake. Because this happens quite often, I am aware of this and keep my foot on the brake until other vehicles are out of the way to avoid bumping into them. When this happens, I can cruise at 30 miles per hour without having my foot on the accelerator, I can slow down or stop by applying the brakes but the engine RPM stays at 1,300. If I stop and shut off the vehicle and restart, the operation goes back to normal but occurs again later. The Hyundai dealer has had the vehicle back 9 times but the issue continues. The first few times, they could not find an issue, I returned to the shop when this was happening and the service manager and a technician observed this condition, the EGR valve was replaced. Was OK for a bit but condition returned, the computer was then replaced. Condition continued. Brought the vehicle back and a scan was done and system “re-learned. After a short time the condition returned. Went back to the service center and they did another scan and another re-learn. Condition returned 4-5 days later. Problem still not resolved. Have 59,850 miles on the vehicle, warranty expires at 60,00 miles. This started around July 1, Now October 5. Waiting for a loaner so the service center can drive it around until the situation occurs and they can bring it in immediately for diagnosis. This is the same issue as reported for the same year vehicle in July 2022.

ENGINE
The vehicle is burning oil at a high rate in a short period of time, a known issue that is affecting thousands of other people, and Hyundai refuses to issue a recall to fix this issue. If I forget to add oil every 500-1000 miles, I risk the engine locking up while driving. Their cars are dangerous to drive and are unsafe to be on the road with other drivers. They put profit over the safety of their customers.

UNKNOWN OR OTHER
To whom it may concern, I was driving on the highway with my sunroof down as the weather was nice. I started to hear a flapping sound and got off at the next exit. I tried to close the sunroof but it would not close. It looked like the windshield thing for the sunroof detached on the passenger side and blocking it. A minute after I started to drive the sunroof panel detached and flew off my car. It shattered on the street in front of another car that was driving behind me. This car had to swerve to miss being hit. I immediately called the Hyundai dealership crying and the women promised me a manager would call me back. I told the lady I dont know what to do. Do I call the police because a 30-pound glass panel is shattered on the street? Do I call my insurance? She said she would have the sales manager and service manager call me back. I was so shaken and scared from the event I called out the rest of the day from work. I had to uber my son home from school because I was nervous to drive the car. If I didnt get off the next exit; would my sunroof have flown off and caused a car accident? It was really scary to see the panel fly off like paper and almost hit another car. That I could have cause another person to have an accident and they couldve gotten hurt. The whole thing is just crazy to me. I did not get a call back from hyundai yesterday. I will try to reach them today. I will uber my son to school this morning as one of the pieces is sticking out and still flapping. When I looked up the recall on my car for this; I could not believe that the hyundai fix is super glue? This car really is glued together.... Thank you to listening to my concern and you can reach me anytime at [XXX] . Thank you, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I bought my 2022 Hybrid Sonata in the summer of 2022. I drove it down to the beach (8 hour drive) about a week after purchasing the vehicle so at that time there were less than 100 miles on the car. We didn't use the vehicle for the week we were at the beach and when we tried to unlock the car to load our bags, the key would not unlock the car and we couldn't get in. We had to manually unlock the doors and call roadside assistance because the Battery reset button would not jumpstart the car. I was assured that there was no issue with the car by my local Hyundai dealership and that this was "normal." I have had the car die on me countless times while it sits idle in my driveway if I don't start it at least every other day. On August 8th 2024, my car was dead and I was able to jump it with the Battery Reset button. The next day, it was dead again. Upon jumping it for the second time in 24 hours, the check engine light came on. I took the car to the dealership to run diagnostics and the hybrid battery has failed their tests. Now I am waiting on my car with a loaner vehicle that I cannot drive out of state. I was told by customer service that they have had this problem with several other customers and some had to wait TWO YEARS for their battery to arrive and car repaired.

STRUCTURE:BODY
My 2016 Hyundai Sonata (pearl white) paint is peeling in many parts of my car. I went to Delray Hyundai where I purchased it in 2019. In August of 2023 I showed a supervisor and she set up an appointment for me to bring in the car for pictures. After Delray Hyundai took pictures I waited and waited to hear from them. I went to the dealership and spoke to the supervisor I was dealing with and she keep giving me excuses why they couldn't do it at that time, she keep telling me they didn't have a loaner car for me, to call or come back. I was frustrated but felt like they were going to take care of the problem. Her name was Piper. Finally after many months I was told they wouldn't do anything for me, and I was told by a worker to try Coconut Creek dealer because they have a paint dept. Well I'm [XXX] old and by myself and I cannot get there. It's very far away and I would have to travel [XXX]. I asked if they would bring the car there for me and was told no. I called Coconut Creek Hyundai and they told me no they couldn't help me. I love my Car and always got compliments on it but it's peeling so bad that it looks awful and I would never get the true value if I traded it in because of the failed paint. I have read and seen pictures of many other people on the internet that have the same problem. Can you please help me. Now it's more than the one side the other side of the car is peeling Thanks INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

STEERING, ENGINE
My engine burns oil like crazy. At least 1 qt every 1,000 miles or less. Took to dealership and was given a hard time about it having an issue. Now my power steering light keeps randomly coming on. I'll feel the steering start to get hard to steer. Thought I needed belts so I replaced both serpentine & water pump belt but it still happens. When my power steering light comes on and steering wheel locks up, I have to put the car in park & rev the engine to get the light to turn off. Mechanics said all pulleys are in good shape so not sure what's doing it. My lights also start to flicker when power steering light comes on. I have a new altenator and battery so it's not caused from that. I have no idea what's causing it but it's extremely dangerous!!

The power steering on the vehicle keeps locking on its own! The dealership say they can’t do anything because once you turn the car off for a certain amount of time it stops and goes back normal. Not safe for driving happens on highway can cause deadly accidents

Car is overheating. Took it to a mechanic They replaced the thermostat but car is still overheating, jerking and so much more. The mechanic wants to charge more to fix it. I got a second opinion from another mechanic and after he reviewed the paperwork from the first mechanic. He searched my vin number and told me to contact this number because my vehicle is on a recall list. So I need someone to contact me about where and how we can get my vehicle fixed.

ENGINE, ELECTRICAL SYSTEM
Around the 70,000 to 80,000 mile range, I began to notice that I needed more frequent oil changes. Additionally, when making turns, the oil pressure light would illuminate. I reported these concerns to the service manager, Steve Purvis, at Noblesville Hyundai, who advised that the light simply indicated the need for an oil change. Due to the ignorance of Steve Purvis, I took my vehicle to Hyundai of Carmel, where the issue was not addressed until I reached 97,000 miles. During this time, the valve covers were replaced twice, yet there were no active leaks, and the problem persisted. Hyundai subsequently denied my request for an oil consumption test to further diagnose the issue. I then took my vehicle to a different shop, where a mini oil consumption test revealed that my car burned over 2 quarts of oil from Friday to Monday. Additionally, my start/stop system has ceased functioning, preventing me from starting the vehicle. I have also noted that there are open recalls for Hyundai vehicles, yet my VIN is not recognized under these recalls. I have incurred significant expenses related to these ongoing issues. My safety has been put to risk because the oil can burn completely out and cause the car to break down in the middle of traffic like it has before. Hyundai dealership has confirmed the car has an oil burning issue, as well as an independent shop by the name of Auto Tech in Indianapolis. Auto Tech has also confirmed that the start/stop system is causing my car to not start. The oil pressure light is not consistent when my oil gets low. Some times it comes on, other times it does not.

Over the last 3 months at least a dozen times the 12v auxiliary battery is completely dead after parking the car outdoors for an hour or so. This poses a safety issue, especially at night because you cannot easily access the car. You have to fumble around trying to get the key hole cover off in order to use the key supplied in the fob. Once you get access, you then have to press the 12v reset button in order to get the car started. This issue has been reported on the Hyundai sonata forums since the introduction of the 2020 sonata. At this point the dealer has not been able to find the issues as they say it has been occur while they have the car. Asking for the problem to occur while they are watching is unrealistic . Their calls to Hyundai tech support has been useless as they claim to have not heard of this issue.

ELECTRICAL SYSTEM
This has happened three or four times now while I have been driving. While driving, my electrical system will "black out"/"power down"/"shut off." Everything on my dashboard turns off/goes black. My lights turn off. It is like my car shuts down for 2-4 seconds, then turns back on and I can continue to drive. There is no warning, sound, or anything. My car will just abruptly shut off. It is random too. There is no pattern that could help me determine what could be potentially causing this issue. It just happened again last night, while I was on the highway going about 70 mph. This could not only hurt me, but other people on the road. What if the next time my car powers down for a longer period of time? Who is to say what could potentially happen? I intend on scheduling an appointment with a Hyundai dealership to take a look at this issue. But I figured that because this has happened three or four times now, it will probably happen again, and other people are probably having this issue too. It could be a potential defect with the electrical system.
