  My car is involved in the class action lawsuit because of engine failure and fire with my 2016 Hyandia Sonota. I have concerns with the above issue because of knocking in the engine and using 1 quart of oil every 400 miles. Hyandia extended the Power train settlement for life time. Yet, they denied to do anything about my car because or 98,700 milage. Dealer said only way Hyandia will do anything if the engine goes out. Hope it just goes out instead of catching fire. Need help, if you settle take care of the customer. Should take care of the customer before settling .

  My 2016 Hyundai Sonata experienced a sudden engine failure while in operation with no prior warning lights or symptoms. The engine seized unexpectedly, creating a safety risk. This failure appears consistent with known engine defects affecting Hyundai Sonata vehicles of this model year. Hyundai Motor America denied my claim without addressing these known defect patterns.

  My 2016 Hyundai Sonata is sitting at the Red Hoagland dealership in Winter Haven, FL after the engine started knocking. Rather than continue driving it and risk an accident with our 19-yr old child driving it, or risk worse damage to the engine, I had it towed to Red Hoagland service department. This occurred less than a week after we had it at the dealership for the third and final oil consumption test. These tests were being conducted as part of Hyundai’s process to identify the known engine issue with this model. Each 1,000 mile test revealed that the engine was consuming approximately 3.5 quarts of oil per 1,000 miles (approximately 1 month timeframe). Despite the results of the tests and now the engine failure, Hyundai has denied the claim on the lifetime warranty of the engine. Their stated reason is “out of warranty caused by time in service and mileage on the vehicle.” The mileage on the vehicle was 143,260 on 10/29. Apparently to Hyundai a “lifetime warranty” on an engine that is known to fail due to this oil consumption issue does not mean “lifetime” but only less than 145,000 miles. I will appeal this decision and if they do not honor their lifetime warranty on this known issue they will hear from my attorney and hopefully the NHTSA will also help to enforce what Hyundai should have already done rather then making me go through this additional effort and trouble.

  Wind deflector came loose on highway after recall was performed. The wind deflector was originally reattached in 1996 shortly after purchase. The recall doesn't take into account that the manufacturing issue may of been previously repaired. I believe when the "recall" was performed(2020) the lack of removing the previous adhesive created a weak bond enabling the wind deflector to become detached. Attached is a copy of the recall instructions which contains no step to remove previous adhesives or check for previous repairs; only the use of alcohol to remove dust or particles. Hyundai corporate followed through on an investigation Case Number #[XXX](December 2024) finding that the recall was performed and they had no ability to investigate the proper method for subsequent repairs.

  I was driving to work when my car stuttered then reduced power allowed me to pull to shoulder of the road at the same time my check hybrid system light came on with all others on dash. Car would not restart. Had it towed to the dealership where I’m told they will diagnose next week.

  On November 10, 2025, my 2016 Hyundai Sonata Hybrid (VIN [XXX] , approximately 150,000 miles) experienced a sudden loss of power while I was turning right and accelerating into traffic. The vehicle immediately entered limp mode with flashing warning lights and audible alerts. The vehicle lost normal propulsion and could not accelerate properly, creating a dangerous situation as it was blocking a traffic lane. I was forced to limp the vehicle into a nearby parking lot to get out of traffic. The vehicle was not safely drivable afterward and was towed home. A few days later, the vehicle was towed to Murdoch Hyundai in Lindon, Utah, for diagnosis. The vehicle was found to have diagnostic trouble code P1326, which Hyundai identifies as activation of the Knock Sensor Detection System (KSDS) related to connecting-rod bearing wear. This condition is part of Hyundai’s known engine defect and safety recall/warranty extension programs. During inspection, the dealer observed that the valvetrain did not show signs of neglect or sludge, which is inconsistent with oil starvation or severe maintenance neglect. This further supports that the failure is consistent with the known connecting-rod bearing defect addressed by Hyundai’s KSDS safety recall, rather than a maintenance-related issue. This is a safety issue because sudden loss of propulsion or reduced power while entering traffic creates a high risk of collision. Hyundai customer care has been unwilling to open a new case number or escalate review, and the dealer has indicated possible denial of engine replacement coverage based on incomplete oil-change records, despite the vehicle exhibiting the KSDS safety condition. I am requesting NHTSA review of this safety-related defect and the manufacturer’s handling of KSDS/P1326 failures.

  I am writing to bring to your attention a critical issue affecting my 2016 HYUNDAI SONATA 4 DOOR SEDAN, that warrants investigation and public awareness. Hyundai cars are currently plagued by ENGINE OIL CONSUMPTION PROBLEMS that ultimately lead to ENGINE FAILURE, due to there being NO WARNING LAMPS, MESSAGES, or OTHER SYMPTOMS OF THE PROBLEM PRIOR TO THE FAILURE. This is a concerning issue that remains largely unknown to most customers. When these issues arise, car owners such as myself, are often left 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, I am forced to endure long waiting times for MY 2016 HYUNDAI SONATA 4 DOOR SEDAN, THAT HAS BEEN INSPECTED and, then DENIED FOR an ENGINE REPLACEMENT, and face additional months of delay for them to explain why. The situation is exacerbated by the lack of loaner vehicles and no assurance of rental reimbursement. This leaves countless individuals burdened with repair payments for stranded vehicles. My personal experience has been with Ourisman 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 are experiencing the same problems 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 SAFETY RISK AND places them in DIRE and DEADLY HARM. I implore all News Media outlets to conduct an investigation into these concerns and help shed light on a situation that demands immediate attention

My safety was at risk because when it happened at first it scared me and I didn't know what happened. 2nd if it had came all the way off it could have flown into someone else's windshield and causing them to crash or swerve to miss it flying in the air. I did mention it to the dealership when it was there, but rather they looked at it or not I have no idea. No one else has inspected it. No warning lamps or other signals appeared before hand.

  I have been going to the dealership since July as my engine light was not shutting off. I kept being told that there were no loaner cars and that they could not fix the problems I was having kept putting a band aide on the issue and saying that I would have more problems. They told me the cat converter would need to be replaced but it was an engine recall issue. They had a loaner car for me for one day told me it was fine that it would probably go again I had them check the car again and they filled the oil and sent me on my way. Now I was on the side of the road with no car and am now being told they can’t work on my car until March which since I have been seeing them for 4 months now for the same problem that just got worse you would think they would try to help me. Instead they told me to go somewhere else turn in my dead car or I have to tow it and then tow it back in March. I can’t afford this right now it is terrible and there are no cars out there they are so expensive. Please help me I am very poor and have 2 jobs that require me to drive.

  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.

  This event took place on or about [XXX]. A month or two prior, my vehicle had just undergone a safety inspection with over $2,000.00 worth of repairs that were performed with great care, due to noticing loss of power upon acceleration. I'm currently living in Wyoming, and the engine blew while driving on the highway in Colorado, causing a mild underbody fire while driving at high rate of speed. At this point, my safety is of great importance and concern, the radiator had internal damage that was not disclosed by the initial dealership, that took possession of my vehicle. So I truly don't know what or who to believe (which parts have been properly repaired on my vehicle or what has not), it took me to personally tow my own vehicle back to the local repair shop here in Wyoming, and the repair shop could not get power to the vehicle. Eventually the repair shop realized that the original "ground" bolt that "was" on my brand new battery was stripped out of place and replaced with a tapping screw, that's why no power was getting to the vehicle as needed to operate properly. The repair shop also noticed internal damage to the radiator (inside bay) with 2 puncture holes (that was not disclosed at any point of interacting with the dealership. Now my safety is an extremely huge concern. Again, I don't know if the vehicle is in worse or better condition with the most recent repairs that have been done to my vehicle. The engine was confirmed to have been damaged internally and externally "beyond repair". I was never given an exact description of any and all damages "requested by me at the time I called the dealership". My son and I are still without our vehicle, we are in dire need of transportation, and to have our vehicle back and running in a condition that is sufficient to perform for our everyday needs, to get back and forth to doctor appointments, etc. We are in great hopes to get this unnecessary nightmare behind us, so that we can press on with our lives....INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

  My 2016 Hyundai Sonata with the DOHC GDI Theta-II engine is experiencing severe engine oil consumption consistent with Hyundai's known TXXI/TXXC extended warranty defect. The oil pressure warning has flashed while driving or braking, the engine runs rough when slowing down, engine has made knocking noises, and there is smoke/vapor with a burnt oil smell when removing the oil cap after driving. The oil level drops rapidly between changes despite proper maintenance. This issue poses a risk of engine failure, stalling, or fire while driving. I have maintained the vehicle on time with all oil change receipts. A Hyundai dealership refused to perform the required warranty diagnostics even though this issue falls under Hyundai's extended warranty for Theta-II engines. This is a serious safety concern, and no corrective action has been taken.

  My Hyundai is experiencing severe and continuous engine oil consumption that creates a safety risk. The vehicle loses a significant amount of oil within 1,000–1,500 miles, sometimes showing almost no oil on the dipstick despite recent oil changes. There are no external leaks, no burning smell, and no visible oil under the car. The cause remains UNKNOWN, but it appears to be internal engine burning or a manufacturing defect. I have taken the vehicle to the Hyundai dealer multiple times. They performed oil consumption tests but either reported “normal results” or did not provide clear explanations. The issue continues exactly the same. I also contacted Hyundai corporate, but no meaningful assistance or goodwill support was provided. The dealer acknowledges no leaks but still refuses to repair or replace the engine. This problem is dangerous because the oil level drops without warning lights or error codes. If I do not manually check the dipstick, the engine could run dry and seize while driving. Sudden engine failure on highways or in traffic can cause accidents. I now have to frequently top up oil just to keep the engine alive. I have maintained the vehicle properly and completed all requested tests. The cause is still UNKNOWN, but based on similar Hyundai cases, it may involve piston rings, valve seals, or internal engine wear. Many Hyundai owners report the same issue, suggesting a broader defect. The dealer’s only advice is to “keep monitoring oil,” which is not a safe long-term solution. This defect poses a serious safety concern and financial burden. I am filing this complaint so NHTSA can investigate, as the engine may fail unexpectedly, putting me and others at risk.

  The vehicle consumes an excessive amount of oil causing the engine to stall out

  My engine has catastrophic damage due to not being notified by the manufacture about a recall that occurred years ago. Had I known about the recall, I would’ve addressed it and prevented the engine failure. It is currently sitting at a Hyundai dealership as they are working with me to try to get Hyundai to cover the costs of the engine failure. So far, they refuse. My safety was put at risk due to the car stalling out on me at any given moment. I cannot and have not been able to safely drive this vehicle therefore, it has been sitting mostly unused as I continue to make payments on it over the last 6 months. This problem is a reoccurring issue with my vehicle and others and there is a class action lawsuit against Hyundai for it, in which I missed the deadline because I just recently became aware of this. The vehicle has been inspected by a dealer and was noted as “catastrophic engine damage” needing a $7,000 new engine. The engine light first turned on about 6 months ago for me, but I was in the process of moving across the country that same week, so I put repairs on hold until I was settled in to my new area. Now that I have the time, and after the car had been sitting for 6 months, I took the car in to a dealer where they told me the bad news. It is worth also mentioning that this is the 2nd time I’ve had damage done to my vehicle due to lack of recall notice. However, the 1st time my car was damaged, the dealer was able to fix the issue free of charge. This time around, they are needing to charge me $7,000 but are pushing that I get Hyundai to cover the costs due to the reoccurring issues with these recalled engines and their failures. I regularly maintained my vehicle and kept most of that documentation, so I know I did my part in taking care of my car. This is simply due to lack of recall notice that could’ve prevented a large bill for myself and my car being out of commission and unsafe to operate without probable cause of an engine fire. Please help

  Car unexpectedly stopped working and became disabled while trveling 40 - 50 mph on the freeway. Complete loss of power. Danger of a collision on the freeway. All dash lights and warning lights came on. Car would not shift and would not accelerate. It was unsafe to drive and could hardly move off the road. The first year I had the car the engine light came on and loss of power. I took it to the dealership immediately. Whenever I took the car to the dealer they said there were no codes and the car was was fine. The entire time I owned the car I would lose power on inclined roads and engine light would come on and off. Last week November 18 the car stalled and could not drive uphill again risk of a collision from the rear. I took the car to the dealer they said the car was fine. The dealership has never tried to fix the problem and claimed they could not duplicate the problem. Today 12/1/2021 the car stopped operating on the freeway completely and I had to tow it to the dealership. This car has been a safety hazard within the first year and Hyundai has done anything to address the problem.
