2016 Hyundai Sonata Complaint Log

The hood open sensor is displaying that the hood is open when it's been closed and is latched.

INTAKE CAMSHAFT CVVT COVER AND SENSOR INTAKE CAMSHAFT CVVT OIL PLUG PLUG Exhaust Manifold I am up to date on all me oil changes and everytime I get and oil change the oil goes so fast! This has actually been happening ever since I got the vehicle. My acceleration has been decreasing when I get an oil change.

My vehicle has been consuming oil very often. I have done regular maintenance on it since I purchased the vehicle. I first noticed the issue in August of last year. My remaining oil in my engine before an oil change would be little to none. I brought it to a Hyundai Dealership and they told me they can do nothing. They told me if my check engine light came on and my engine seized, to call them. I had a check engine light of O2 sensors being out. I replaced those. My engine continued to consume oil. I had another check engine light come on last week and it was my timing sensors. They went out. I replaced those and my technician looked inside my engine, and it is filled with metal shavings. My timing chains will go off if I drive my vehicle and my engine will no longer function. Hyundai in Sioux Falls, South Dakota told me numerous times they did not see why my engine was consuming oil. They also told me they would have a tow truck come get my car to repair if it was seized or damaged. They refused to last week. They told me the only way to fix my engine is if the code of P1326 was present. My code now is P001000. I am stuck without a car because i cannot drive mine.

The contact owns a 2016 Hyundai Sonata. The contact stated that while operating the vehicle, the check engine warning light remained illuminated. The vehicle also experienced reduced power and would not properly accelerate. The vehicle was taken to a local mechanic who determined that the engine had experienced excessive oil consumption. The vehicle was later taken to the local dealer who performed an oil consumption test and determined that the engine was faulty and needed to be replaced. The vehicle was not yet repaired. The manufacturer was notified of the failure, but no assistance was offered. The failure mileage was 78,000.

Recall code on my engine p1326

Both rear view mirrors on the doors have quit working cannot adjust them. apporx. mileage 86000 miles.

My car was burning through oil fairly quickly. I had to refill my oil in between oil changes. I was also getting oil changes about every 2k miles until I realized it was not normal. I contacted Hyundai about an oil consumption test on December 19th. I did not hear back until almost 2 weeks. The email did not ask me what I needed but basically said” you’ve talked to someone if you need something let us know” I had called in to check the status. Not sure why they thought this was resolved. About a week later my engine failed. Hyundai will not fix my engine because it does not fall under warranty. From what the mechanic told me, my car has carbon build up due to the burning oil which caused my cylinders to crack. I don’t know much about cars but oil is not suppose to burn that fast.

Engine began misfiring, spark plug coated in oil which indicates piston ring defect. I get regular scheduled maintenance, often needing oil far before maintenance would be due. This is a KNOWN issue and Hyundai is NOT TAKING RESPONSIBILITY.

I am writing about my concerns on a 2016 Hyundai Sonata SE that I purchased for my daughter in October 2023. After purchasing I took it to my local Hyundai dealer to have it checked out. It was one of the cars that came with a lifetime warranty for the rods DO TO A DEFECT.On January 2024 my daughter was driving on the freeway when all of a sudden it just stopped accelerating and when checked it was a Knock sensor detection system. The dealer took it in and inspected and said it was a defective sensor and replaced it.This made me uncomfortable as I felt the sensor did its job and it was just a matter of time before the rod blew through.During the next few months it became very apparent that the car was going through unbelievable amounts of oil.It had a ticking so we replaced all the spark plugs and noticed oil saturating the plugs and realized a leak in the valve cover gasket which was also replaced.We thought this might be the cause but no oil was on the ground and nowhere on the engine.I just thought it was burning oil but no indicator lights were going off. The car could have no oil and it would not let us know. She's lucky to drive 300 miles a month.She has complained of a strong gas oder and we replaced 2 gas caps and went back to the Hyundai dealer.They told us there's a problem with the fuel filter and pump.If we pay $273 of inspections it might cover it if it's a failing part, and when I did the oil change the car was very low on oil despite the fact that we check it monthly and put 3 quarts of oil in the car.Her car is consuming 3-4 quarts of oil per every 250 miles.This could cause her engine to fail and possibly throw a rod which given the fact she has already taken out one Knock sensor it is just waiting to happen.So as oil disappears every few hundred miles without a warning the engine locks up and if a rod punches through onto the exhaust this can cause it to stall and potentially catch on fire especially when it wreaks of gas from the fuel filter.

On the way home after I purchasing my son his 2016 Hyundai sonata limited, he noticed his oil light come on and he stopped to check his oil and it was almost empty. He got an oil change and called the dealer and they told us that it was probably the oil change place that didn’t tighten the drain cap. We took it to them and they said no issues with the cap. Went back to Hyundai and when you open the hood the engine is shiny and coated in oil . They would not do anything for us , the car was at 117k and they told us to drive it till it knocks and fill it and maybe Hyundai would replace engine . Hyundai did not warranty this cars engine. He has had his car now for 5 months and puts over a gallon of oil in it a month. It started misfiring, so we replace his spark plugs and noticed oil all over the spark plug number 2. This was a one owner car, that showed she took good care of it, and that is why we purchased it. We are stuck with this car and it is not safe and my son is 19.

The contact owns a 2016 Hyundai Sonata. The contact stated while driving 65 MPH, the vehicle stalled. The contact stated that several unknown warning lights were illuminated. The contact had the vehicle towed to a local dealer, where it was diagnosed and determined that the engine had seized and needed to be replaced. The vehicle was not repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 158,000.

I am reporting multiple serious issues with my 2016 Hyundai Sonata Sport 2.0, which has only 30,000 miles. Despite the low mileage, the vehicle is experiencing major safety and quality problems. The Electronic Stability Control (ESC) light stays on constantly, indicating a system failure. On startup, the car sometimes applies the brakes by itself, and there’s a loud noise like something is stuck or grinding. The traction control light also comes on during this. While driving, the car will suddenly slow down on its own, even when I’m not braking. When I press the gas pedal, it barely responds or takes too long to accelerate. Sometimes, this happens at the same time as the ESC warning, which feels extremely unsafe — especially on highways or in traffic. The push-to-start button often delays before the engine turns over, which is abnormal. The A/C system only blows warm air, regardless of temperature settings, and no cold air comes out. I also have a serious issue with the paint peeling off in large chunks from the body of the car. It’s happening despite proper care, and I’ve seen other Hyundai Sonatas of the same year with the same issue, which suggests a widespread paint defect. These issues have not yet been diagnosed by a dealership, but given the low mileage and frequency, I believe this model may have serious defects in safety systems and paint quality. I’m very concerned for my safety and request a full investigation.

While driving the car a noise came from the engine and I lost acceleration and then the car just died in the middle of busy traffic. The car was stuck in busy traffic till it could be towed since it wouldn't restart. After doing research it is a known problem with Hyundai and Kia engines and there are thousands of people like me and Hyundai refuses to take responsibility and puts the blame on the consumer stating they didn't maintain the vehicle. I could of been seriously injured by this and a lot of others are in jeopardy with these faulty engines.

I Bought a Hyundai Sonata in the spring of 2018 from a previous owner. Before buying the car, I contacted Hyundai and they told me engine issues would be covered. In December 2022 I talked with the customer service national office and told me I was lucky that I had two engine warranties, one up to 120k miles and the other unlimited. I was told to check my oil usage every month to ensure a warranty. The car started using oil this fall 2023. I took the car to the dealership as requested by Hyundai. We have paid almost $1000 for tests. Hyundai of Noblesville says the car is drinking oil 2.8 quarts for less than 1000 miles, a test Hyundai requires. Making you drive a car with less than half its engine oil is self-destroying the engine. Hyundai is not willing to pay for the repairs. Being required to drive a vehicle until the engine ceases to get the engine covered under warranty is a very dangerous practice that risks the lives of ourselves and others. The car has less than 100,000 miles.

The contact owns a 2016 Hyundai Sonata. The contact stated while driving at speeds of 50 - 60 MPH, the vehicle stalled. The check engine warning light was illuminated, and the vehicle shut off. The driver made several attempts to restart the vehicle while attempting to accelerate. The vehicle was towed to the dealer three times. The first diagnostic report was that the knock sensors had failed and needed to be replaced. The knock sensors were replaced twice however, the failure remained persistent. The manufacturer was made aware of the failure. The failure mileage was 70,000.

My hyaundai is burning through oil every 500-1000 miles it will be completely empty

I am writing to report a concerning issue with my Hyundai Sonata 2016 regarding excessive oil consumption. Every 1000 miles, the vehicle requires approximately 1.5 quarts of oil, if not more. This rapid depletion of oil presents a significant safety risk for driving the car. Upon contacting the dealership regarding this matter, I was informed that they have no knowledge of such issues, which contradicts the numerous complaints I have read and heard from fellow Hyundai owners experiencing similar oil consumption problems. The dealership has suggested conducting an oil consumption test, which they advise will cost us a minimum of $280. However, it seems unfair to incur this expense for what appears to be a common manufacturing defect, particularly since our vehicle is no longer under warranty due to its mileage of 110,000 miles. I firmly believe that Hyundai should take responsibility for any related repair expenses arising from this issue. I urge you to address this matter promptly to ensure the safety and satisfaction of Hyundai customers. Thank you for your attention to this concern. I look forward to your prompt response and resolution.

On the evening of 11/28/2023 I had my vehicle parked in my garage of my home when my smoke detectors went off. I went to my garage to discover it was full of smoke and it particularly was coming from the front of the engine I had my son call the fire department and poured water on the small fire as it was still smoking when they arrived. there is visible burn marks on the engine hood from the fire

The contact owns a 2016 Hyundai Sonata. The contact stated while driving approximately 30 MPH, the vehicle started to make an abnormal knocking noise. The contact stated no warning light was illuminated. The contact pulled the vehicle over and stopped. The contact turned the vehicle off and on. The contact stated that she was able to shift into drive (D) and while depressing the accelerator pedal the abnormal knocking sound was heard. The contact stopped and had the vehicle towed to an independent mechanic. The vehicle was diagnosed, and it was determined that the engine had thrown a rod due to lack of engine oil and the lower part of the engine needed to be replaced. The contact stated that she had had the oil changed two weeks prior to the failure. The contact stated that she had not noticed any oil stains on the driveway at her residence prior to the failure. The vehicle was not repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 70,000.

I own a 2016 Hyundai Sonata and on vacation in Florida the cap to the shark Finn Antenna flew off on the highway. I noted there are recalls on newer versions of the Sonata but not on the 2016. I feel that is a problem that Hyundai should address as it is a safety hazard and could cause an accident resulting in injuries. Also the cost to replace the antenna is almost 500 dollar as they do not just sell the cover for the antenna. Thank you for any help you can provide in addressing this issue as I do not want anyone to get hurt because of this faulty problem with the antenna cover.

Engine is burning is oil at least 1,5 qt on 1000 miles, added 7 quarts of oil in 3500miles, dealership is playing around and says everything is ok, did a oil consumption test and wrote down that is burning 0,5 qt and don’t want to recognize that the have to change the engine on warranty

I am writing to bring to your attention a critical issue affecting Hyundai car owners that warrants investigation and public awareness. Hyundai cars are currently plagued by oil consumption problems that ultimately lead to engine failure, a concerning issue that remains largely unknown to most customers. When these issues arise, car owners are often left to grapple with uncooperative dealerships that either deny the problem or offer minimal assistance. Even Hyundai corporate and extended warranties fail to provide adequate support, frequently citing owner negligence as a reason for denial. This occurs despite the fact that engine sludge buildup is inevitable, even with consistent car maintenance. Furthermore, car owners are forced to endure long waiting times for their vehicles to be inspected and, if approved for an engine replacement, face additional months of delay. The situation is exacerbated by the lack of loaner vehicles and no assurance of rental reimbursement. This leaves countless individuals burdened with car payments for vehicles either stranded in garages or idle in driveways. My personal experience has been with First Hyundai, and many others have voiced similar grievances. Numerous complaints have been filed with the Better Business Bureau (BBB) and the National Highway Traffic Safety Administration (NHSTA), yet little action has been taken to aid the thousands of people who lack the resources to rectify this issue. It is imperative that attention is drawn to this matter as Hyundai's approach to selling cars with hidden engine issues puts customers at risk and places them in dire financial straits. I implore the Boston Globe to conduct an investigation into these concerns and help shed light on a situation that demands immediate attention

The contact owned a 2016 Hyundai Sonata. The contact stated that while her son was driving at approximately 45 mph, the check engine warning lights illuminated. The vehicle began to shake, lost power, and failed to accelerate. The driver pulled over and noticed smoke, and the vehicle caught fire. The fire department was on the scene and extinguished the fire. It was unknown if a police report was filed. There were no reported injuries. The air bag did not deploy. The vehicle was towed to a tow lot. The local dealer was not contacted. The vehicle was not diagnosed or repaired.The insurance company deemed the vehicle a total loss. The manufacturer was not contacted. The contact mentioned that in 2021, the motor may have been replaced.The failure mileage was approximately 62,000.

The contact owns a 2016 Hyundai Sonata. The contact received notification of NHTSA Campaign Number: 21V749000 (Exterior Lighting, Electrical System) however, the part to do the recall repair was not yet available. The local dealer was made aware of the issue and confirmed parts were not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact had not experienced a failure. Parts distribution disconnect.

I am having electrical issues with my 2016 Hyundai Sonata plus the other recalls. It started as issues with the lights on the driver side. I have replaced several bulbs and the entire light even and still have issues with the lights working properly. Now the issue is the battery, alternator or the starter. The starter had to be replaced as I was advised by Hyundai dealership when my engine had to be replaced, per recall. I had to purchase a starter, that was three times the amount at the dealership because the one that is manufactured in the auto stores is not correct, so it should not be the starter as it is only 1 to 2 years old. I have had the alternator replaced as well as 2 batteries and I’m still having issues. It cut off completely while driving on more than 1 occasion. There was no warning, no power steering, gear lock, no lights & no power so I could not move and almost had a major accident. It is definitely a safety hazard even after the repairs, it has happened again! My vehicle is currently not working because the new battery will not hold a charge and they both have been replaced. I’ve been having other electronic type issues with this vehicle. My information center has not worked for the past 8 months or so! I reported this to Hyundai and they agreed that it could be a part of a previous recall, and advised me to go to the dealership to have it repaired. The dealership refuses because they don’t have required information to show it as a Current recall and want to charge me half the price of a new car to repair. I am not the only one experience this as my research has led me to several other Hyundai owners experiencing the same issues. It is not fair that they cannot be corrected as these are things that are none of consumer fault & should have been high demands to proper repair or recall being a major safety issue as it can cause a horrific accident! Shame on Hyundai for putting their Hyundai customers at risk & through so much chaos!

Yesterday while driving my vehicle engine stalled and wouldn't go over 40 MPH, about 10 seconds later the engine would not go over 15 MPH.

My husband (Scott) was driving the car on Florida highway 408 eastbound approaching the exit 21 on 10/12/2023 around 8 am. Scott heard something pop suddenly and saw fire shooting out from both sides of the car in the rearview mirrors. Upon noticing the fire, he tried to slow down to pull over the car, but brakes failed (went to the floor). A police officer on the road happened to see the fire so he drove next to my husband's car and Scott yelled at officer that he had no brakes. The officer went ahead of Scott to help Scott's car slow down. When approaching uphill slopes by the exit, Scott was finally able to use the emergency brakes to come to a complete stop. The fire engine came right away and put out the fire which took over 20 minutes. My husband is handicapped and him walking away from such car catastrophic fire unharmed was near miracle. Two weeks before the fire, I happened to take the car in for checkup at Greenway Hyundai Orlando and the 2.5 hour inspection found nothing wrong with my car. I wanted my car checked because my car stalled briefly pulling out of a parking space a few days earlier.

I constantly have to purchase bottles of oil and put into the car in between oil changes. The oil burns so fast and the car does not give a low oil signal on the dash. This is a known issue because the dealer recommended I return in between the oil change for a free top off because Hyundai engines are known for burning oil. I spend extra money every 2 weeks buying oil.

The White pearl paint is bubbling and peeling right above the driver door window. It's getting worse by the day. While driving with my window open a piece about the size of a nickel flew into my car and hit me on the face right under my eye. If it had flew into my eye I surely would have had an accident. Took car to Delray Hyundai on August 3,2023 for pictures and was lead to believe it would be taken care of. I'm getting the run around from them. I have read many many articles on the internet about this problem, can you help me or assist me in what I can do to get this taken care of. Thanking you in advance for your help.

The driver side mirror control will not move the mirror left to right. The button will only move the mirror up and down.

On 10/06/23, I went to the Meriden Hyundai Dealership to get my transmission and brakes serviced. During the multi-point inspection, the technician noticed that the oil pan had a hair line crack at the drain plug site. I found that peculiar especially since my oil changes have been performed at the same place for the past 5 years. My last oil change was performed on 09/09/23. The technicians never mention any problems. I did not notice any oil leaking. The oil was actually being trapped in the undershield. I have contacted that company and they have conducted an investigation. They do not find any fault with their workmanship. However, something is wrong. I see there are other Hyundai vehicles having trouble with their oil pan and drain plugs.

THIS VEHICLE AND MODEL HAVE A DEFECTIVE ENGINE; I HAVE MADE SEVERAL ATTEMPTS SINCE I PURCHASED THIS VEHICLE FROM THE DEALERSHIP TO HAVE THIS ISSUE CORRECTED, AND NOTHING HAS BEEN DONE. THIS IS A VERY COMMON ISSUE WITH THIS PARTICULAR ENGINE, AND IT IS A WELL-KNOWN PROBLEM; THERE ARE SEVERAL CLASS ACTION SUITS REGARDING THIS ENGINE, AND THE MANUFACTURERS STILL HAVE NO RESOLUTION FOR IT. THE VEHICLE REQUIRES CONSTANT NEW OIL IN BETWEEN OIL CHANGES AND HAS BEEN LIKE THAT SINCE NEW. THE ENGINE BURNS OIL, AND IT IS NOT GOING ANYWHERE, NOOEN SEEMS TO KNOW.

On September 25, 2023, I was involved in a motor vehicle collision while driving my Hyundai Sonata 2016, during which the front driver-side airbag failed to deploy despite the impact being significant enough to cause injury. This non-deployment represents a malfunction of the airbag system, including its sensors and deployment components, and aligns with issues already reported in class-action complaints involving Hyundai vehicles, making my case further evidence that an airbag defect exists. Because the vehicle was declared a total loss by my insurance company and later sold at auction, the physical component is no longer in my possession now; however, I retain documentation on accident-related records that clearly show the airbag did not deploy. The failure of this critical safety system placed my safety at direct risk because the protective barrier intended to reduce impact forces was absent, resulting in greater injury than would reasonably be expected had the system functioned properly. The problem has not been reproduced yet because the vehicle was transferred to insurance immediately after the incident and was not repairable. But working with accident reconstruction engineers on this matter. Prior to the crash, the vehicle displayed no warning lights, SRS messages, or other symptoms indicating an issue with the airbag system, and at no time before the collision was I alerted to any malfunction that would have suggested the system would fail at the moment it was most needed.

Engine seized on the highway

Was driving home when my car went into limp mode - couldn’t pick up speed to keep up with the flow of traffic. This seems to be due to the car’s engine knock sensor being triggered. It is impossible to get it to the dealer in a timely manner. We are having to wait half a month before it can even be diagnosed.

Car stalled check engine light came on took to auto zone said a engine problem

DROVE ABOUT A BLOCK AND WHILE MAKING A LEFT TURN I NOTICED MORE SMOKE COMING FROM UNDER THE HOOD. PULLED BACK INTO JOB'S PARKING LOT (SINCE IT WAS CLOSE) AND WITHIN 5 MINUTES THE ENGINE WAS IN FLAMES. FLAMES WERE EXTINGUISHED, BUT CAR WAS NO LONGER DRIVEABLE. INSURANCE CLAIM WAS FILED AND VEHICLE WAS DEEMED A TOTAL LOSS. CAUSE OF ENGINE FIRE IS STILL UNDETERMINED PER INSURANCE COMPANY.

Car has been consuming oil fast since around 75,000 miles. Car is under 100,000 miles and I have been told by an independent shop that it basically has piston ring failure which means engine failure.

Steering sticks and releases under pressure at 60/65+ mph on interstate. Very difficult to keep vehicle in lane consistently. Constantly correcting both right & left to maintain straight line is extremely fatiguing especially on long trips. Safe driving at highway speeds is compromised and presents safety concerns for occupants as well as motorists nearby in addition to the apprehension it creates wondering if you're able to correct the steering drift before having an accident. There aren't any dashboard warning indicators when this happens Reported to dealer in central Florida on March 22, 2024 and dealer ordered parts Ref TSB 23-ST-003H. Hyundai Extended warranty TXXO. Factory has sent some parts to dealer twice that I know of and each time vehicle has been taken to dealer I've been told they were not what was needed. On most recent appointment of 12/19/24 I was told the needed parts were unattainable from Hyundai. On 3/20/2025 the dealer has offered to put in some of the parts they have as a possible solution but repair has not been scheduled. Dealer said they had another vehicle that took over a year to repair. This has been 14 months. We're only using this vehicle at slow speeds locally, anticipating complete failure, as we don't trust it for highway use.

The first time my engine light came on was about a month after I had purchased it. The dealership told me to go to autozone to see what it could be. Report said it could possible be an oil clog or oil change. I got an oil change and the light was off. Light came on an every now and then but the car was driving fine. I got another oil change at the recommended mileage. My car won’t start now, I thought it was a battery issue so I took it in to a mechanic to have it looked at and they said I need a new engine.

See attached document for complaint

My 2016 Hyundai Sonata started using and leaking oil in August 2023 when it had about 129,000 miles and when you tried to go faster than 55 miles per hr. it would not accelerate. We feel there is a danger to drive it in traffic. We took it to the dealership in Pensacola, FL. They found a valve cover gasket had multiple leaks which they replaced. Found a code P1326 (whatever that means), Performed T3G campaign and followed a flow chart and BCT test passed. Don't know that any of this addressed the fact that the motor won't accelerate. Charged me $3,000 for something. Car ran okay for a while and started doing the same thing again. In June of 2024, took it to local mechanic who ran diagnostics and replaced a coil and plugs which cost another $600. It ran a little better until August 2024 and took it back to local mechanic who did another diagnostic and replaced 4 plugs and PCV valve for another $300. It's now November 2024 and the car won't accelerate over 55 mph and we can't use it to drive to work.

The contact owns a 2016 Hyundai Sonata. The contact stated while driving at 55 MPH, other drivers started beeping the horn and shouting that the vehicle was on fire. The contact immediately veered to the side of the road. The contact then noticed flames under the front end of the vehicle, near the engine location. There was no warning light illuminated. The contact stated that the fire was extinguished independently. There was no injury sustained. The contact stated that the vehicle was towed to her son-in-law's repair shop, where it remained. There was no police report filed. An unknown dealer was notified of the failure and informed the contact that a repair fee would be charged for the engine replacement. The vehicle was not diagnosed nor repaired. The contact related the failure to an unknown recall. The manufacturer was notified of the failure and advised the contact to take the vehicle to the dealer to be diagnosed. The failure mileage was approximately 108,000.

found me driving on I 75 and I put the Cruise Control at 70 miles, instead of maintaining the speed at 70miles the vehicle accelerated to more than 90 miles per hour I had to quickly put my foot on the brake otherwise I could have an accident with the vehicle from the front, after all this happened, I felt the car was losing speed, I tried to accelerate but it did not go over 60 miles per hour. I took it to the mechanic and they did not detect anything in the vehicle's computer. This vehicle also turns off at times when you are driving and it turns off it also spend too much oil motor , I started looking for information on this model of car and I see that there are more than 550 people who have the same problem as me, this is an unsafe vehicle for the road

Engine is constantly burning through oil. I would get my oil checked 4 times more just to make sure I had oil and even then it would burn empty. I did not have a leak. This cause my engine to blow. This was unsafe as I could have been driving when this occurred. This is being confirmed by a certified Hyundai mechanic. No warning. Other Hyundai cars have a recall for this SAME engine issue but not my model and make

Engine failure. Metal in the engine oil pan. P1326 code. No warranty coverage and no recall. Replacing the parts myself. Vehicle went into limp mode without warning. Oil bypassing one of the pistons. Lower end was loose.

Bought the car on 08/20/2022. On 09/07/2022 we took the car back to Allen Turner because the engine light was flashing and the car would not go over a certain speed. There were metal shavings in the oil. It was throwing code P1326. They did an update on car and told me the cylinder walls were scored but the motor had a lifetime warranty no matter what happened to it. Every time we would have the oil changed, we would have to add 3 quarts of oil every 10-15 days. The vehicle stalled out at a very busy intersection nearly causing a wreck with my teenage daughter driving. Had it towed to dealership and they said it needed a new motor because it has one of the defective motors in it according to the VIN. Then they told me it was oil consumption and they could replace spark plugs and oil and it would be drivable but it would stall, it would break down and the motor will seize. It is only a matter of time. Hyundai will not honor the warranty on it because the motor is not seized up. The service manager told me to drive it until it seizes and then they would cover the engine replacement. The vehicle is not safe to operate. It is a safety hazard for anyone to drive. Hyundai will not stand behind their products when they already know it is defective.

Timing chain failure at 150k. Unknown cause prior to failure at around 135k miles. Only intermittent vibration or mild vibration while accelerating (pass. Side) Sudden loss of power going into limp mode with check engine light flashing.

There was no warning light illuminated. The contact stated that the failure recurred while driving on another occasion. The check engine warning light illuminated. Additionally, the contact stated that on the third occurrence, the vehicle lost motive power and shutoff after pulling into a parking lot. The check engine warning light, the battery warning light, and the low oil pressure warning light were illuminated. The vehicle was towed to an independent mechanic, where it was diagnosed that the engine had seized and needed to be replaced. The vehicle was not repaired. The dealer and the manufacturer were not notified of the failure. The failure mileage was approximately 127,000.
