The headlights are stating headlight low and triangle with a exclamation ⚠️ appears.

Car stalled then started smoking followed by flames. We exited vehicles and ran a safe distance away and called 911

WHEEL LOCKED UP WHILE DRIVING, RED LIGHT CAME ON THE DASHBOARD. ONCE I TURNED CAR OFF AND BACK ON IT WAS FIXED, THIS IS THE SECOND TIME THIS HAS HAPPENED. ANY IDEA WAHT IT COULD BE?

Knocking noise in the engine, super loud sound, engine sized up because there was a lubrication failure from the oil pump, rock arm bearing was gone on cylinder 3 crankshaft catastrophic damage, and tulsa hyundai send an application to hyundai USA and they refuse to fix my car because the previous owner didn't do 4 recalls that are not even close to be related to the problem in the engine. Abs light recall, seat belt recall, parking brake light switch recall and smart junction box recall, none of this has anything to do with the negligent fabrication on rotating parts in the oil pump, and rock arm bearings, this is very upsetting and disappointing that a recognized brand like hiunday did such a big mistake in fabrication and they found the perfect stupid excuse to wave their responsibility to the customers that invest their money on this cars

I am the only owner of a 2015 Hyundai Sonata: in December 2018 the car had a new engine put in when the mileage was 106,894 due to the engine burning oil much too fast. On 9/20/2023 while getting an oil change Jiffy Lube told me the oil was almost empty, as the engine was burning oil way too fast again. This was at mileage 162,148. I checked the oil periodically to make sure the engine had oil. I added a quart around 163k and on Feb 3, 2024 I checked the oil at 165,000# miles on it barely had any oil in. I filled with about four quarts and then I started the car. Upon starting there was an explosion in the engine and all the oil drained out. My complaint is Hyundai replaced a know defective engine with the same defective engine, which unknowingly to me but me at risk driving the car. I am lucky the engine did not blow while driving on the highway. In researching after the engine blew the second time I found there was class action suits for this same problem in the past and there was some settlement. I do not know if the NHTSA was involved

The contact owns a 2015 Hyundai Sonata. The contact stated that the engine was consuming an excessive amount of engine oil. There was no warning light illuminated. The contact was frequently topping off the engine oil between scheduled oil change service. The vehicle was taken to a dealer and a 3,000-mile oil consumption test was performed. The test concluded that the vehicle was consuming an excessive amount of engine oil. The contact rejected the results. In addition, the contact stated that the brake pads were frequently replaced due to the vehicle shuddering upon the depression of the brake pedal. The manufacturer had been notified of the failure. The vehicle was not repaired. The failure mileage was approximately 60,000.

Car was going approximately 50 miles an hour on a side street when warning lights went on, brakes stopped working, and the engine smoked and appeared to catch on fire. Car was steered into a parking lot and abruptly placed in park. Occupant grabbed valuables and quickly exited the vehicle. At that point, the front of the vehicle, under the hood went up in flames.

The same as all other Hyundai I’ve seen from 2011 to 2019. Error code reads P1326 manufacturer control. the vehicle shut off on me 65 on the highway without warning. hook up the car to the computer and it has returned no code so we troubleshoot by that the starter was burnt up and we replace it everything‘s fine for two days. Then of course I get the manufacturer code P1326 and find out that 100s are not thousands of Hyundai have been recalled for the same issue. Also, like all other complaints, I’ve seen car went into limp mode or reduced power mode and the check engine light is flashing

Engine has an oil consumption issue.

About 20000 miles ago, I was informed by my servicing center that my Sonata came it without oil on the dipstick. My car currently has 90k and my engine is burning about 1qt of oil every 1000 miles. Many people have been having issues with these engines from Hyundai and Kia. My engine has been a part of a class action lawsuit regarding this problem but my specific model is never included even though the engine is. I've been checking my oil regularly and keep oil in my trunk at all time since this first happened but I'm getting close to my car being out of warranty. When I get my oil regularly changed at 3k - 4k miles, well below the the suggested 6k, is it my responsibility to add oil all the time or is it the responsibility of Hyundai to replace my engine for being faulty? My warranty expiration is coming up and I'm keeping this engine alive by adding the needed oil and even though my engine is part of a class action lawsuit. I'm not going to get any benefit of warranty extension or replacement from that lawsuit as my specific model isn't listed. I have a Sonata Eco 1.6 liter and it always the Sonata 2.0 and 2.4 they are listed even though the Tuscan with a 1.6 engine, the same as mine are included. There are thousands upon thousands of these vehicles on the road burning oil. It's bad for the environment and a ticking time bomb for everyone driving them. We need an investigation into these faulty engines and an actual fix from Hyundai and Kia.

Car has a distinct burning smell when driving it. This has been going on since late summer of 2023. I moved to a different state from NC to AL. Had it inspected and because it wasn’t smelling at the time the mechanic stated there were no issues. Also, got a recall for campaign 993 with my vin number from Hyundai and no dealership will honor it bc when they look up the vin it says no recall due. Please help me rectify this situation so I’m not out of a car. I don’t know if it’s bc I relocated that I’m not getting cooperation. I’m not able to even schedule an appt with the dealership bc of this. Please help.

I was driving down [XXX], about 20 miles southwest of Atlanta when I saw flames and smoke come underneath the hood of my car. I pulled over to the right shoulder and I was able to exit the vehicle before the entire front engine compartment was melted and engulfed in flames. Local FD responded and extinguished the fire. FD was unable to explain what may have caused the issue. Vehicle is a total loss. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The car has been having problems with oil consumption. The problem became known in 2022, but the dealer/service department (Frank Hyundai, National City, CA 91950) did not take care of the issue and did not care about safety. The dealer told me, "Your car is OK." On 7/3/2023, the engine light came on. A second round of oil consumption tests began along with a 90,000-mile service, including replacements of filter assy and gasket, four new tires and front and rear brakes, spark plugs, suspension/steering repair, shaft assy, engine repair, cooling system service, and fuel induction service. Shortly after, the car slows down even when my foot is on the accelerator. It feels as though the vehicle will stop. I can see the rpm gauge erratically going up and down. The car lurches or jerks. I reported the jerky problem to the dealer at the second 1000-mi oil consumption test, but the dealer did not make any diagnostic tests or repairs because, per the dealer, "it did not jerk while we test-drove it." The problem continues.

The problem continues.

When I press on the brake the vehicle accelerate before it slows down. Sometime the car accelerates for no reason. This has been a recent problem for the past few months. The engine has been replaced from a prior recall.

My break went out while trying to make a stop.

Panoramic Sunroof randomly exploded while i was driving down the street. Appears to be a known issue and a class action lawsuit has been filed.

In the first incident(2020) after the check engine light was on, the car was towed and needed the valve cover and fuel pump gasket replaced due to leakage. In November of 2023, the check engine light kept flashing and again the car was towed to the dealer. The valve cover was removed and we were told a new engine was needed, but we would have to pay for it. We were old that we have neglected to keep oil in the vehicle.

Between oil change intervals, the check engine light flickered intermittently. I checked the oil level and it was very low. I added 3 quarts of oil and took it to my Hyundai dealership. They performed all the oil consumption tests and told us that the car now burns seven-tenths of a quart every 1000 miles. Hyundai USA claims that this is acceptable oil consumption. I disagree of course. I called my service adviser at the dealership and requested that Hyundai replace the engine because a 2015 Hyundai Sonata with only 70K miles should not be burning that much oil. He agreed and told me to keep monitoring the oil consumption and if it burns 1 quart or more after 1000 miles, to bring it back.

Oil consumption issues. Had a brand new factory motor to replace original motor due to engine failure from oil consumption issues on June 29 2020 at 154,285 miles. The new motor only has 56,665 miles on it and I'm having to add extra oil in between changes because it is bone dry after about 1800 miles from oil change each time.

The wheel of my car as I would turn literally locked on me and the car went off to the other side of roadand engine shuts off .this seems to only happen when I make a right turn quickly it is random and I never. Know when this will occur it hurt my hand because the wheel snapped out of my hand as to keep straight . So it's very scary I am looking for help to get itfixed . But I won't feel safe driving it until then I had to buy another car so that I could drive meanwhile I see what I can do about this car

The vehicle is demonstrating clear signs of engine failure based off the symptoms Hyundai states on its website for the rod knock bearing recall (no power, enters limp mode, white smoke out tailpipes, etc.) Hyundai states vehicle passes testing. Engine also has oil consumption issues, has had its PVC value fail twice in ten months, and burns through 1.5 qts of oil every 496 miles (has failed all 3 consumption tests). The vehicle has stalled out on multiple occasions and risked my/my child's life, has required cylinder cleanings and fuel injection cleanings, and the engine gets extremely hot. This is the second failed engine in the Sonata, and Hyundai has not stated if they will replace it.

My hydraulic brake booster went out, Very dangerous i almost had an accident, the car doesn’t stop, there are no brakes the car would not stop I’f the hydraulic brake booster goes out you have no brakes and if you’re over 50 miles an hour the E break barely does anything it just sounds like you grinding into the ground. Very scary and I had a child in the car. Towed car to Hyundai.

After Hyundai Dealership performed RECALL 953, vehicle is having uneven engine idling, especially while stopped at traffic lights/stopsigns and when starting the vehicle. It is noticeable enough that I am concerned the theta ii engine is failing, or about to fail.

My car was smoking from under the hood. I had it towed to the dealer. Service dept said valve cover. Picked car up 2 days later and less than 1/4 mile from dealer the car was smoking, I called service department was told it was normal. Stopped at red light, smoking intense, turned back to dealer. I lost my brakes, stopped by the grace of God. Passerby told me to get out, my car was on fire. 2 minutes later it was fully engulfed. Total loss.

My son was driving my car home from work and while waiting at a light, he went to go in the car would not move the engine. He just died right there in the middle of the street on him. He was stuck in the middle of the street for quite some time waiting for a tow truck because it was way too dangerous for him to get out of the car. It was during traffic hour. The car only had like 48,000 miles on it. After repaired by the dealer car started having other issues with the engine light coming on with intake manifold but dealer claimed that part is not covered, which that part is part of the engine that they supposedly replaced.

Insurance companies are not proving insurance because of rise in theft of Hyundai vehicle. Now they are asking to install remote start kit for physical engine immobilizer. Cost of this installation is $350 - $500, Hyundai is not entertaining this issue. Hyundai are saying we have done anti theft software update but insurance companies are saying that is not enough.

The failure mileage was approximately 60,000.

Hybrid system warning comes up often and everytime I take it to get assessed, something different is getting fixed. These repairs are all expensive out of pocket repairs. The problems continues to happen and I’m constantly repairing something different.

Steering Column making Clicking sound. Steering Wheel completely locked during a turn.

Vehicle displayed hybrid warning while moving through an intersection on a highway. The car's engine turned off along with the power steering and brakes. Had the light not been in my favor, I would have been unable to stop on a high speed highway with oncoming traffic.

I am 86 years old. I bought the car brand new so I am the original owner. I have kept the car perfectly maintained and garaged from the day I bought it. My wife is also 86. She and I are the only ones that drive the car. To date, it has 73,822 miles on it. The main issue I am having is random, unpredictable stalling and hesitation when trying to accelerate. We have also had unintended acceleration. This always happens at the worst times which causes grave concern for our safety. We have taken the care to the dealership here in Cape Girardeau, MO called Chris Auffenberg Hyundai. They've charged me $130 only to tell me nothing is wrong. I have continued to try to work with them and they now have decided a new fuel pump will fix this which is $730. I have noticed there are already hundreds of complaints on the 2015 that all say they have the same exact issues I am having but this dealership doesn't seem to care. Here is what I have read. "The most common issue in the 2015 Sonata lies with its faulty throttle control system, which can cause stalling, hesitation, and even unintended acceleration. Currently, there is no fix from Hyundai." My dealership will not acknowledge this even though it is public information. I feel like they are going to keep replacing parts and are taking advantage of me. [XXX] is the Service Manager at this dealership and I am not happy how he is handling this. Please let me know if there is any additional information I can provide. INFORMATION REDACTED PU

Trying to break after being hit to prevent hitting another driver . Ended up hitting the driver still and my car ended up catching on fire .

The driver's seatbelt does not retract. The engine is burning oil.

The contact's friend owned a 2015 Hyundai Sonata. The contact stated that while her friend was driving at 20 MPH, a motorist informed her that there was a fire visible underneath the hood. As her friend opened the driver-side door, the vehicle became engulfed in flames. The contact's friend was taken to the hospital where she sustained severe burns to the left side of her body. The contact's friend had her skin grafted from the right side of her body to repair the severe burns sustained to her left thigh and ankle as well as other parts of her body. A police and fire report was filed. The vehicle was completely incinerated due to the failure. The remains of the vehicle were towed to an independent tow yard where it was deemed a total loss. According to the fire report, the fire was caused by an unknown electrical failure malfunction; the source of the failure was undetermined. The dealer nor the manufacturer had yet to be notified of the failure. The vehicle was destroyed. The failure mileage was 71,820

This is the second engine that has been replaced for the same issue. It had a connecting road bearing failure & went into limp mode.

Car stalls intermittently. When at a stop sign or red light, then when my turn to go I step on gas peddle, car starts to go, then stalls. I have to let off gas pedal and step on it again to get car going. This is dangerous as it leaves me in intersection and vulnerable to oncoming traffic. I had a mechanic check it out and they cleaned Throttle body, but that did not fix problem. No trouble codes showing up apparently.

Over the course of this last year I've been in contact with Hyundai motors of America and my local Hyundai dealership after my 2015 Hyundai was showing signs of engine issues i was traveling along i-95 with my child at highway speeds when my car suddenly came to a stop causing panic and what could've been a tragic accident. had I wasn't able to regain control of my car. I was told to schedule an appointment which I did that same day taking my car in for service where I learned about several recalls on my car make and model. I was informed that a update was need along with knock sensor detecting software since that initial contact I've taking my car back to the dealer regarding smell of something burning and excessive oil consumption. my local dealership have since performed Nemours oil consumption test finding issues and picking and choosing what information is being sent up to corperate. I had the service manager tell me Hyundai is not willing to honor the repair unless my car engine brakes down or catch fire which is very likely. the service manager then proceeded to state I would in fact need a new engine eventually. "I have everything documented " which then I contacted Hyundai motors America for a second time and was told to return to dealership where a case was open not once but twice and ended up closed stating Hyundai motors America not honoring the extended warranty on my vehicle. this is very hazardous and concerning cause my car again on 9/15/2023 came to a sudden

Consuming 1 quart of oil every 2 weeks, which is about 800 miles of highway driving for me.

Hybrid car with various hybrid system failures that results in sudden loss of power while driving. this has occurred 3 times to me while on the highway (I-75 in South FL). Car suddenly loses power, could not accelerate but I was able to get off the highway safety. This has been reproduced at the dealer and they first replaced the hybrid generator then the hybrid battery and ECM and now it occurred again yesterday while I had 2 children with me and now they blame the transmission. This is a dangerous car that should be recalled and investigated for the true cause of sudden and unpredictable power loss.

Noticed a smell of gasoline in the passenger compartment and took it to my local mechanic. Upon his inspection he found that the gas smell was caused by a crack on the plastic connector for the fuel line on top of the fuel pump. He showed this to me and recommended replacing the fuel pump as the connector is built into the pump and there was no proven way to fix the leak. Said leak caused gasoline fumes to fill the passenger compartment and therefore a risk of igniting a fire in the passenger compartment.

The contact owns a 2015 Hyundai Sonata. The contact stated while driving approximately 30 MPH, the sunroof detached from the roof of the vehicle. The cause of the failure was not yet determined, and the vehicle was not yet repaired. The vehicle also experienced severe engine knocking and the vehicle was taken to the local dealer who diagnosed that the engine was faulty and needed to be replaced. The engine was replaced, and the vehicle was repaired. In addition, several safety features including the Lane Departure, Cruise Control, and the Forward Collision Avoidance system intermittently malfunctioned. The cause of the failure was not yet determined. The manufacturer and local dealer were notified of the failure. The failure mileage was approximately 92,000.

The car has had multiple issues with the hybrid system. I’ve taken it to the dealership about 4-5 times. They “fix” the issue but a little while later I’m having more hybrid warming issues. This last time I took it to a different dealership, paid for a diagnostic test, and was told my hybrid system was bad but because it was repaired too many times instead of replacing it, it’s no longer covered under warranty. The issue from the last diagnostic test showed the master brake cylinder was faulty, I replaced it but I’m still having the same issue. The mechanic I took it to did their own diagnostic test and it showed there is an issue with the hydraulic booster, high pressure accumulator short term charge. When I searched the issue, I’ve found that many people are having the same issue with the same car/year as mine. I contacted the manufacturer and they are still not willing to fix it even though it is a possible defect in the car.

Engine light came on, checked the oil and there was no oil in the engine.

I purchased a 2015 Hyundai Sonata from Carmax on 12/6/22 in Tinley Park, IL. The motor on the car went out on 8/30/23. I took my car to family mechanic to find out that the motor has a hole in the back of it. I had it towed to Happy Hyundai on 9/1/23 in Oak Lawn. I was by Happy Hyundai that they will not be able to look at my car for for 4-6 weeks. Carmax claimed to have did an all point inspection on the car but yet the motor went out. I’ve only had the car for 8 months. The motor went out while I was driving on the express way going over 50 mph. My safety and others around me was put at risk. Luckily me and no one was hurt. The only time the engine warning lamps came on while I was on the expressway and that’s when the car started to slow down while trying to get to the right side of the expressway.
