ELECTRICAL SYSTEM, ENGINE, UNKNOWN OR OTHER
43000 miles on car. original owner. new battery. car does not cold start in the morning. all electronics light up, but engine doesn't start. This is a known issue from all the posts i found online, yet Hyundai has not issued a recall. I paid 300 for a battery 2 weeks ago and the issue didn't resolve. Now i am being told by dealer it is the starter and it's not covered because my 5 yr warranty is expired (my car is 6 years old). This is a known safety issue across the 2018 Sonata line. This should be a recall or bulletin, instead I have to come up with hundreds of dollars more to replace a starter on a car with ONLY 43,000 miles.

STEERING, UNKNOWN OR OTHER
My car suddenly stopped while in drive, with a forceful jerk like someone hit me from behind. This nearly caused a 3 car crash. It grinds when you put it in park but the car doesn't move in drive nor reverse.

UNKNOWN OR OTHER
My vehicle is in the shop now and will be due to 12volt battery charging system failure. I have taken the vehicle to the shop 4 times now because vehicle will not start unless you hit the reset 12volt button. The dealership told me that they were surprised that I was able to start the vehicle. I was told that it is the NHTSA Campaign # 24V868000. This vehicle is not included in this campaign number but it should be. Hyundai needs to include this make and model to the recall so other drivers don't have the same issue and so that they don't find themselves stranded.

VEHICLE SPEED CONTROL, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
Hello, thanks for reviewing. I recently bought a brand new Hyundai (VIN provided) and the speedometer intermittently is inaccurate. Maybe 50% of the time, which I would argue is less safe since I can’t reliably tell what my speed is. When it is an issue, it’s worse the faster I drive. It breaks the 10% threshold I’ve read about around 30mph, where it will say 26mph. I brought it to the Hyundai dealership and they claimed they couldn’t replicate the issue so they won’t fix it - but it’s intermittent and I have picture / video proof from multiple dates. I used various speed sources to be sure. I found some Hyundai forums online where many others have the same issue. The speedometer is an important safety feature, not to mention other dependent features, like cruise control. Happy to provide proof by request.

ELECTRICAL SYSTEM, EXTERIOR LIGHTING
When driving early in the morning while it was still dark outside, the car had what seemed to have been a sudden loss of electrical power. The audio for the radio cut off, then the screen for the radio and speedometer went blank, and the headlights also went out. This all lasted for a couple seconds when this happened and then everything came back on fine. I normally would think that this is a defective alternator which it probably is and would be covered under warranty, but after researching this problem I found out that it is a common issue with the 2024 Sonata. I feel that this warrants a safety recall which I seriously doubt will happen but it needs to. If it causes problems with headlights shutting off at night then this is a safety issue. Who knows what will happen if the headlights shut off on you at night and you couldn’t see where you were going because of it?

ELECTRICAL SYSTEM, SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
I was driving and my car started beeping and the wheel jerked to the left and my car slowed down from 65mph to 20mph and almost caused me to have an accident. After I replaced the breaking module, my battery started shorting out and my car once again jerked off to the side and then slowed down abruptly from 65 mph to 20mph.

ENGINE
Approximately 6-8 weeks ago, I was driving home and my oil light began turning on and off. This had never happened before. It was nighttime and I was only a few miles from home so I continued driving. The next morning, I checked the oil to find that the reservoir was bone dry. There had been no warning light whatsoever prior to this incident. At this point, the vehicle had about 65,000 miles on it. I had to put 2 quarts of oil in before it would even register on the dipstick so I could get it to my mechanic. Upon arriving to his business, he explained that Hyundai is well aware of this ongoing issue of oil consumption but they are doing nothing about it. I had not driven excessive miles without an oil change and faithfully get it changed between 3,000-5,000 miles, which is perfectly acceptable for this vehicle. I have all receipts from these changes. I have begun to maintain a record indicating the oil that I have added over the last 1,700 miles. It has been 2.5 quarts. The morning I brought the car to my mechanic I reached out to the Hyundai dealership and was told I would need to pay for a diagnostic, then two oil consumption tests. I declined and promptly reached out to Hyundai corporate. They told me the same nonsense and then offered to have their consumer division reach out to me. Ultimately, that person told me I would need to do the same thing, so they were entirely useless in facilitating any reasonable resolution. I subsequently found out about the oil consumption problem that thousands of people have reported in various models and years. I joined a few Hyundai oil consumption groups on Facebook and now realize how many people have been impacted by this issue. I still owe $5,600 on the car but feel that the issue will not be handled by Hyundai and don't wish to have ongoing concerns with driving the car and constantly topping it off with oil. As a result, I feel that I am forced to pay off this car and buy something else.

UNKNOWN OR OTHER, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
On three separate occasions, while going very fast (60-78 mph), the automatic emergency braking system turns on. The warning lights flash and there is some type of warning noise. I don't even know if it starts to break because it scares me so much, I just press the gas. It turns off within a couple of seconds, but that is not the point. If I didn't react so fast, I am unsure of what could actually happen.

POWER TRAIN
The push button shifters do not shift gears, unless the brake is depressed. On a slight incline, it is natural to shift from forward to reverse without braking leaving the driver in the wrong gear. So I have often started forward expecting to go backwards. I accidently ran over a portable toilet trying to quickly reverse out of a driveway on a slight incline. I hope no one has run over a person this way. I have had other close calls. This system is far more dangerous than lever style shifters. Even a little mistiming between brake and shift can leave the car going the wrong way.

FUEL/PROPULSION SYSTEM
What component or system failed or malfunctioned, and is it available for inspection upon request? The Fuel Tank expanded, was leaking gas from the gas tank opening. The expansion of the tank caused the metal plates/panel under the back seat to popup, where my child sits. Which caused a gap in the door. ir seepage from the back seat passenger door to where the fuel was leaking out the gas tank and also the fuel gauge on the dash was fluctuating. People on the highway was flagging me to let me know fuel was leaking. The fire department had to come and clear it. How was your safety or the safety of others put at risk? My child and I could have been seriously injured or killed. As well as people on the highway. It could have exploded. You can smell the gas in the car. The gas was coming out the gas tank on the side. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, it was confirmed by Hyundai of North Charleston 8485 Rivers Avenue, North Charleston SC, 29406 and it was also checked by the insurance adjustor. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? It was inspected by the Insurance representatives State Farm Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No I took it into the dealer and they said it was fixed and it did not fix the gas coming out the tank. And the same issue happened again on [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ENGINE AND ENGINE COOLING, STEERING, ELECTRICAL SYSTEM
The contact owned a 2012 Hyundai Sonata. The contact stated that various functions on the steering wheel including the horn, cruise control, and other electrical functions; all failed to operate as needed. The vehicle was taken to an independent mechanic where the contact was informed that a warranty had been placed on the vehicle for the clock spring which they linked to the failure. The steering wheel also began to stick soon after the diagnosis. The dealer was notified of the failure; however, the dealer could not provide an appointment until months out. The contact then stated that while driving at 65 MPH, the vehicle began to hesitate upon the depression of the accelerator pedal. The contact began to pull over as the EPS(Electrical Power Steering) and several other warning lights appeared on the instrument panel. As the contact opened the door, a fellow motorist had also pulled over to alert the contact that the vehicle was on fire. Soon after exiting the vehicle, the entire vehicle quickly became engulfed in flames. The fire department quickly arrived on the scene and extinguished the fire. The contact was not injured, no other occupants were inside the vehicle, and the contact was unsure if a fire or police report was filed. Some of the grass and trees in the area had caught fire as a result of the failure. The remains of the vehicle was towed to an independent tow yard. The dealer nor the manufacturer had yet to be notified of the failure. The vehicle was completely destroyed. The failure mileage was approximately 125,000.

STEERING
Lost power steering in heavy traffic. Was able to move safely to a parking lot and stopped. A light came on with a steering wheel at the same time the power steering went out. Turned off vehicle and when started again no light on the dash and power steering was ok. After 2-3 more miles of driving lost power again with the light came back on. Was able to park safely. Started it the next day and all seemed ok but did not drive. 2 days later started ok and no light on dash, within 1 mile light came on then 10 seconds later the power steering stopped working. Was able to drive slowly to the mechanics and he confirmed that it needs a new module inside the steering wheel.

EXTERIOR LIGHTING
Brake lights become hot enough to melt through housing, hanging loose in the trunk where they can damage wiring and further burn through taillight housing. There was no warning, uncertain how long issue has been ongoing as I only noticed when a light went entirely out. Vehicle has not been inspected since engine replacement under previous recall. Will be available for any inspection on request. This problem has occurred on both the left and right taillight assemblies

ENGINE
Car has been meticulously maintained with the best oil and premium gasoline. The car is only used on the freeway at 60-70 mph. Husband was on his way home and engine light came on. Car started shaking horribly. He had put a fuel injector cleaner in his recent full tank the day before. Drove car to auto zone. Got the code for misfire on cylinder 3. Replaced all spark plugs. Still code. Replaced cylinder 3 coil. Still code. Swapped cylinder 2 coil with 3. Code still on 3. Took it to shop thinking fuel injectors. Car has no compression on cylinder 3. Needs engine. Hyundai has somehow gotten away with not having to replace engines unless they through a rod. This car has the knock update on it. A lot of others are in the same boat as me. Hyundai should be held accountable for faulty engines. It’s not safe to drive an engine with a bad cylinder that shakes violently.
