Engine And Engine Cooling Problems of Hyundai Palisade - part 2

Component: engine / engine and engine cooling description: my 2020 Hyundai Palisade (approximately 155,856 miles) experienced a serious and dangerous engine-related failure that resulted in a vehicle fire. For approximately 8 months prior to the incident, the vehicle was consuming oil at an abnormal rate with no visible external leaks. This condition persisted without clear cause. While my [xxx] daughter was driving, the vehicle suddenly developed a new oil leak, and the engine failed without warning, leaving my daughter stranded on the roadway. Immediately following the failure, the engine compartment caught fire. There were no prior indications of an active oil leak before this sudden failure. The progression from oil consumption to catastrophic failure and fire presents a serious safety concern. This incident created a dangerous situation with risk of injury or worse, and it appears to be more than normal wear and tear. I am reporting this as a potential safety defect involving engine failure and fire risk. Mileage at time of incident: approximately 155,000 miles no prior accident or external cause contributed to the fire. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

On April 17, 2026, while driving my 2022 Hyundai Palisade with approximately 167,000 miles, the vehicle suddenly lost engine power and was unable to maintain normal driving speed. The sudden loss of propulsion created a safety risk because the vehicle could no longer operate normally in traffic. I was able to move the vehicle out of traffic, but it would not restart. I also observed white smoke coming from the engine compartment. The vehicle was towed to matt bowers Hyundai slidell, an authorized Hyundai dealership, where it remains and is available for inspection upon request. The dealership has inspected the vehicle and advised that the engine needs to be replaced. The exact internal component that failed and the final cause of the engine failure remain under review by Hyundai. I do not recall any warning lamps or messages before the sudden failure. The timing of any prior symptoms is unknown. The vehicle had been maintained through authorized Hyundai dealerships. On December 29, 2025, a Hyundai dealership replaced the oil filter housing because of an oil leak and performed a synthetic oil and oil filter change. On March 11, 2026, approximately five weeks before the failure, the dealership performed another oil and oil-filter change and a multipoint inspection. I am reporting this incident because the sudden loss of engine power while driving, the inability to restart, and the smoke from the engine compartment created a serious safety concern. The vehicle remains disabled and available for further inspection.

My car is misfiring. It will not accelerate as it should. It is like bogging down unable to accelerate when it needs to. It’s struggling. Hyundai is aware of the issue and making owners drive regardless while they “wait for a fix”. It’s extremely dangerous. I’ve almost been hit several times trying to merge onto a highway because it will not accelerate. I’ve had total loss of power one time, putting me and my infant in extreme danger. This has been happening since April.

I have been having an issue with my 2021 Hyundai Palisade's engine oil consumption. It is constantly burning oil at a high rate, requiring me to purchase oil constantly. I had it serviced at Hyundai in gurnee, IL. An oil consumption test was conducted. Hyundai corporate stated that my vehicle's engine was not burning oil at the required rate, which prompted an engine replacement. I reached out to corporate because the issue is persisting, but they never responded to my concern. This issue is costing me a significant amount of money, as I have to purchase oil without a remedy from Hyundai regarding my engine oil consumption. As a consumer, it's frustrating because I left without answers on an issue they definitely know about.

I own a 2022 Hyundai Palisade sel. On xxx, while driving at the intersection of [xxx] and [xxx] in [xxx], the engine abruptly lost power, causing a sudden loss of engine power while the vehicle was in motion. This is my family's primary vehicle, and my wife and children were in the car during this incident. On xxx, I brought the vehicle to courtesy Hyundai in [xxx]. The dealer found essentially no oil in the engine despite my keeping up with scheduled oil changes. The dealer replaced the oil and performed a software update described on the repair order as "9c9 c ecu sw update emissions imprv 26-01-010h," and I was instructed to return after 1,000 miles for an oil-level recheck. At that recheck, the dealer's service assistant reported the oil was full. On xxx, before a planned family road trip, I returned the vehicle for another check. The service department found the engine was two quarts low — this was only 4,000 miles after the oil service on April 10, 2026. The dealer stated they requested an oil consumption test but that Hyundai denied the request. Per the dealer's instructions, I returned again after another 1,000 miles, and the engine was one quart low. I am filing this complaint because I believe the excessive oil consumption and the resulting loss of engine power represent a safety defect that has not been remedied. An engine that abruptly loses power while driving creates a serious hazard, including loss of power steering and reduced braking assist, and I am concerned for my family's safety while this condition remains unresolved.

After emissions campaign 9c9, downshifting using paddle shifters on downhill grades, engine failing to maintain speed. Does not slow car down like it did before, seems like no compression. Fuel efficiency / emissions over traditional transmission braking, forcing drivers to use brakes more often to avoid high rpms. Safety risk: the lack of engine braking can lead to brake overheating or fade on long downgrades, lack of engine braking can lead to brake overheating or fade on long downgrades. Above is what google found [xxx] ) when I put in some key words. Here is what I wrote to a [xxx] . My 2021 Hyundai Palisade campaign 9c in your article about the 2022 having the same downshifting issues after the emissions recall was done. Have you heard from other 2021 owners? I use the downshift for breaking/keeping my speed down to save the breaks here in the [xxx] , [xxx] , and [xxx] mountains. Does not function as designed. "loss of engine braking" " high engine revving" did go back to dealer and drove tech around lot. I called back later and nothing they can do. 5/12/26 went to the dealer again, for an appointment. Dealer service manager said it working as designed. Bull, was not that way before. He said if I don't like it, trade in the car. . He also said that I can't compare the palasade to the other cars that have manual shifting. Bull. I said why have them if they don't do anything. . . Tried to explain that I have been driving for over 40 years and have always downshifted every car. This was fine until the emissions recall. Got no place with the dealer. Contacted Hyundai corporate last week, and they should be following up on Wednesday/tomorrow. 5/13/26 left vm for sales gm at bowser today where I purchase the car. Wrote above and more [xxx] contacting you now. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

- engine leaking oil / burning oil - vehicle stuttered while turning left - can lead to sudden breakdown or stalling - dealer performed warranty repair of oil pan and oil filter housing in February. 2 months later, no oil on dipstick. Dealer reports this is a common issue. - manufacturer states one quart of oil lost every 1000 miles is acceptable. Car holds 6 quarts of oil. Dealership oil change is once every 6000 miles. Engine will be out of oil before next oil change is due - car is at dealer with no loaner available. Hyundai corporate contacted and they say this is very common and oil consumption test is next step. In the meantime, no car for us. - vehicle still has 28000 miles under warranty. A simple internet search will show this is an extremely common issue with no fix. - life of engine, value of car, peace of mind, safety of occupants are all a concern.

The contact owns a 2020 Hyundai Palisade. The contact stated that while driving at an undisclosed speed, the accelerator pedal was depressed; however, the vehicle failed to accelerate as intended. Several unknown warning lights illuminated, and the engine seized. The contact stated that while attempting to start the vehicle, the vehicle failed to start. The vehicle was towed to the dealer; however, the failure was not duplicated. The failure reoccurred. The vehicle was towed back to the dealer, where it was diagnosed with spark plug and ignition coil failures. The contact was informed that the spark plugs and ignition coils needed to be replaced. The vehicle was repaired. In addition, the contact was informed that the oil was a quart and a half low. The contact was advised to add a quart of oil to the engine every 1,000 miles. The failure reoccurred. The vehicle was taken to the dealer, where it was diagnosed with a failed solenoid. The contact was informed that the solenoid needed to be replaced. The vehicle was repaired. In addition, the contact stated that since the vehicle was purchased, the vehicle had displayed nineteen fault codes. The contact stated that months later, while driving at an undisclosed speed, the passenger's side sunroof arm deflector detached. The vehicle was taken to the dealer, where it was confirmed that the passenger's side sunroof arm deflector had detached. In addition, the contact was informed that the driver's side sunroof arm deflector was fractured. The dealer attempted a temporary repair using tape, but the failure reoccurred. The vehicle was taken back to the dealer, and the dealer reapplied tape, but the failure reoccurred. The contact stated that the temporary application of tape and debris had detached. The force of the wind caused the driver's side sunroof arm deflector to detach. In addition, the contact stated that the loud sound and the debris from the sunroof were over the contact's head. In addition, the contact's minor child was an occupant of the vehicle at the time o.

A week or so after taking the car in for an oil change, I was on the highway and heard a rattling sound coming from the engine. There were no indicator or warning lights from the dashboard. The car then stopped accelerating. It was on, and the accelerator increased the rpms but the car did not move faster. I safely got home and checked the oil and it had less than a quart. There were no low-oil indicator lights telling me the oil was low. Separately, this week, while driving in the city, the engine again started making rattling sounds and completely shut off forcing me to pull off the road. Again, prior to the shut off there were no indicator lights. I was able to pull to the side of the road safely. I tried to restart the car and it would idle roughly befor the engine shut off again. After waiting 30 minutes, I checked the oil to see if the previous cause was the culprit, but this time the oil was still full. After 45 minutes, I was able to restart the car and drive home. I researched the issue and there are many complaints on reddit about this for this make and model. Since the issue is intermittent and can't be replicated at the dealership, there is no fix offered. I no longer trust or feel safe driving this car, especially on highways.

At about 60,200 miles, my check engine light went off and I took it to the dealer. They told me all my fuel injectors were failing and I had to replace those to include the spark plugs. I understand there is a current class action lawsuit for similar Hyundai vehicles but does not include the Palisade.

When picking up my children from daycare, my 2024 Palisade (37k miles) would not shift into park. It was stuck in the reverse position. It would not shift to any drive, park, or neutral. Even in the reverse position, the car would not move. I applied the emergency brake and had to turn the car off without placing it in park. When I restarted the car, and place it in reverse, the engine made clunking noise. The dash said "shifting malfunction. Service immediately".

In March had issues with driver and passenger seats not moving up and down without getting stuck have to mess with it for awhile to move up or down and sometimes won't go to a directions it can move to seat even though setting it in a certain position every time turn off car and start goes to a position to high up in a way can't get in till you put it down then get in car when moving the 2nd row seat the passenger seat moved front back instead then folding seats 2,3rd row not working correctly found out mid Mar recall 2,3rd row folding issues child died, 3rd row seat belts called corp said do not allow passenger in 2nd, 3rd row till fixed called service said no fix so had wait week later car was hesitating when push gas engine power train warning light came on tow car to dealership they lied proof in writing they lied said fix the seats even though at that time no fix for recalls only reset engine light even though car was giving issues almost broke down they had car 8 day made me pick up car said was fixed proof it wasn't they threaten harassed me to get it I said recalls show on NHTSA still till off not fixed won't come so they said day I had bring loaner car back or they come repo it they removed it from NHTSA site that day said see it's off I said there no way if no fix yet recalls I called many service dept ask went on Hyundai corp main site said fix for seat belt mid may this was April 7 and I ask them to put in writing several times car safe for my 3 yr old grandson they never once say car safe they illegally fraud took recall off the site all to get me come get car got car seats not fixed they said in writing seat belt fixed with tape tape? they put on NHTSA recalls after got car I confronted them then they removed again to not get in trouble to take off then on. But no seats fixed and could not put passenger car barely drove car was still hesitating gas ac loos power not even month later engine light power train issue again but not just light defect cause.

While the vehicle was off and in my garage, the vehicle started on its own and was idling at an extremely high rpm. I was the only person home, the keys were out of reach on a key rack and had not been driven yet for the day. I walked into the garage and found my vehicles engine running at a high rpm and all the electrical displays within the vehicle were compleltely off with only the engine running. I retrieved my keys and my only thought was to start the car, which I did which then brought the rpm down to standard idle. I am extremely concerned as a vehicle idling in an eclosed garage poses extremely high risk to carbon monoxide.

Vehicle shifted into neutral while driving myself and others were put into danger as I was on the highway with no warning.

The vehicle suffered a structural "seam leak" on the pressurized oil filter housing. This was verified by an authorized Hyundai dealer (dealer xxx, invoice #xxx). The failure is a structural crack in the housing component itself, not a maintenance-related seal or filter failure. This defect causes pressurized engine oil to spray directly onto the hot engine block while the vehicle is in operation, creating a severe and immediate fire hazard. Additionally, the rapid loss of oil and oil pressure poses a risk of sudden engine seizure or stalling at highway speeds, which could lead to a crash. Despite being a known manufacturing defect in a critical engine component, the manufacturer has refused to address the safety implications or offer a remedy.

While traveling to abilene TX to see my doctor my check engine light came on. I pulled into the Hyundai dealership and ask the service advisor to plug into my vehicle and let me know what was going on. After he talked to his service manager he advised me that they "where to busy" and the earliest they could get me in would be the next Monday. This was Wednesday. My home is 100 miles from abilene. I asked if he thought it would be alright and he said sure. I barely made it back to big spring before it started clinking and cluttering. It sound horrible. My son said it sounded like it through a rod. He checked the oil and said that I had low oil however my low oil light did not come on. I notified the dealership and was advised that I had to have it towed back to the shop in abilene which I did. After a week passed I was in abilene and stopped to check on my vehicle. Needless to say my repairs are in excess of 20k. New engine etc. And rear suspension is out also. After researching I have found I'm not the only owner with these problems. There are numerous complaints about these problems with the Palisade. This is a danger to all who own this vehicle. Fires, accidents and no telling what can affect us. All these vehicles need to be recalled because of the engine that was placed in these vehicles. The engine is eating oil fast. My oil changes were on time. Hyundai and the dealership are unwilling to offer any help in repairing my vehicle. The parts on the suspension are sub standard. I can't believe they are called the #1 SUV in America! buyers need to be aware of the substandard parts and engine. They also need to be aware the Hyundai doesn't stand behind their product or the dealership either for that matter. I shutter to think of who I could've been on the side of the road with a blown on fire engine. I'm thankful I made it home before the vehicle cratered.

Last year while traveling on vacation, my family was on the interstate crusing at approximately 70 mph when the Hyundai Palisade suddenly started shaking and slowing down. It was shaking so bad, I ended up having to turn on my flashers because the vehicle would not accelerate up hill while pressing on the gas pedal. Thankfully, I was able to exit the highway and located a Hyundai dealership about 15 miles away in jasper, al. The dealership service department was very nice and indicated my engine oil was low. I could not figure out why this happened because we have always changed the oil at recommended intervals but once the dealership changed the oil, the check engine light turned off and we were able to proceed on our trip. Last night, we were traveling from [xxx] International airport back to [xxx] and the same pattern started all over again. After conducting some internet research based on the 2020 Palisade sel, it appears this is a common issue for vehicles just under 100k miles. The reason I am reporting this is because Hyundai corporate should do the right thing in this situation, by offering to replace the engine since I am within the 100k mile powertrain warranty period. I plan to take the vehicle to my local dealership today becuase there are two outstanding recalls, one of which is considered more serious due to a seatbelt latch. We waited over a month to schedule this service and the local dealership cancelled our appointment and didnt even offer to contact us to tell us this. The seatbelt issue is still not resolved and now we need Hyundai to perform oil consumption testing because the vehicle should not be burning this amount of oil while driving at speeds over 55mph or over. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The vehicle would shut off when idling at lights or in reverse and have delayed acceleration after stops. It also would shut off when idling in park. I took it to the dealership summer-fall 2025 and they were too busy to investigate the issue because no alarms were present. The vehicle started doing the same thing and the check engine light came on March 2026. Now it has been in the shop for many weeks because of an fuel injector issue. The dealership service department says all 6 injectors need to be replace, but warranty won't cover them all. This appears to be a common issue with 2021 Hyundai Palisade vehicles and should be investigated for a safety recall.

The contact owns a 2022 Hyundai Palisade. The contact stated that the vehicle was parked for nine hours unattended in the middle of the night; it caught fire. No warning lights were illuminated before the fire. The vehicle was taken to an unknown local dealer two weeks prior for a recall repair and oil change. While her husband was extinguishing the fire, he sustained burns to his arms and face, but medical attention was not provided. Additionally, part of the home was burned. The fire department was able to extinguish the fire. There was no police report filed, no air bag deployment, or crash. The vehicle was towed to a storage facility by the insurance company. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not notified. The failure mileage was approximately 82,000.

I am reporting a recurring safety issue with my 2026 Hyundai Palisade calligraphy involving severe shaking, sputtering, loss of acceleration/power, stalling, and abnormal drivetrain behavior. The first incident occurred at just under 10,000 miles after driving for approximately one hour. While traveling at highway speeds, the vehicle began shaking severely and lost significant acceleration/power. After exiting the highway and stopping, the vehicle shut off. When restarted, it continued shaking and would not accelerate normally. No warning lights appeared. The dealership reported multiple stored fault codes, including transmission-related codes. The codes were reset and the vehicle was returned to me. The same condition later occurred again after extended driving. The vehicle shook severely and lost acceleration, again without warning lights. After being turned off for approximately five minutes and restarted, the symptoms temporarily disappeared. The vehicle has since undergone multiple repair attempts. Hyundai/dealership technicians replaced the flywheel. After that repair, the vehicle developed new shaking/stuttering during startup and shutdown. The vehicle was returned again and a motor mount was repaired/replaced. Two days after receiving the vehicle back from the latest repair, it is now exhibiting another serious drivability issue and appears to remain in first gear or otherwise fails to shift normally. I have video of the severe shaking. A dealership technician also advised me that multiple other 2026 Palisades at that dealership were experiencing similar issues and Hyundai had not determined the underlying cause. I am concerned the vehicle may unexpectedly lose propulsion, stall, or fail to accelerate in traffic or at highway speeds. Multiple repair attempts have not resolved the safety concern. The system will not allow me to upload the videos I have, but you may contact me for them.

It is burning much more oil per 1000 miles than the Hyundai website says is normal. It has kept burning oil at a very high and abnormal rate. To the point of having to carry oil while driving. Nothing happened to make this start, it just began!.

Seats still don't work after recall fix on 2nd and 3rd row. Front seats also do not work when moving 2nd row seat front to back front seat moved instead. Power train engine issues been in Hyundai service 3 times diff services depts and still not fixed have not been able to drive car since Mar due to these issues. Engine light on 3 power train warning codes on. When pushing gas car hesitates and almost completely stops on freeway or on only 2 way highway making it very unsafe to drive. Loos of power to ac and lights due to this issue!.

1. The exact component that failed is unknown at this time. The fire appeared to originate in the driver-side front area of the engine compartment near the headlight. Prior to the fire the vehicle experienced engine shaking and a check engine light. The vehicle has been towed to a Hyundai dealership and is available for inspection by insurance investigators, the manufacturer, or safety investigators upon request. 2. The vehicle caught fire while it was being operated on a public roadway shortly after leaving our residence. Flames were visible from the engine compartment within minutes of driving. This created an immediate safety risk to the occupants of the vehicle and to other motorists because the fire occurred suddenly while the vehicle was in motion. 3. The problem has not been reproduced. The vehicle was towed to a Hyundai dealership following the fire incident and is awaiting inspection. The vehicle is a total loss. 4. The vehicle has been inspected by a tow operator and insurance representatives after the fire incident. The vehicle is currently located at a Hyundai dealership and may be inspected by the manufacturer or investigators if requested. 5. Yes. Prior to the fire the check engine warning light illuminated and the engine began shaking while the vehicle was being driven. Within moments of these symptoms a loud popping sound was heard from the front driver-side engine compartment area, followed by visible flames.

While driving at normal speed, my 2022 Hyundai Palisade suddenly lost power without warning. Multiple warning icons appeared on the dashboard at the same time. The vehicle immediately slowed down and became unsafe to operate. After pulling over, the vehicle would not restart and had to be towed. This created a dangerous situation on the roadway. I am reporting this because I wonder if other owners may have experienced similar sudden power-loss events with this model year. It was fortunate that I was on a secondary road and not on the highway when this happened because it could have resulted in fatalities.

The engine burns 1 quart per 1000 miles of driving.

My 2020 Hyundai Palisade has an excessive and dangerous oil consumption defect. The vehicle consumes approximately 3/4 of a quart of oil every 1,000 miles. At a standard 8,000-mile oil change interval, the engine loses more oil than it holds between services. At approximately 185,000 miles, my vehicle stalled on the interstate with my family inside the vehicle. Upon inspection, the engine was critically low on oil. I added 5 quarts of oil to restore proper level. Critically, at no point prior to the stall did the low oil pressure warning light illuminate. The vehicle's oil warning system completely failed to alert me that the engine was dangerously low on oil. This is a dual failure: the engine is consuming oil at an excessive and unsafe rate, and the warning system designed to protect the driver failed to activate when the engine was in a critical state. I have reported this issue to my dealership and filed a formal complaint with Hyundai motor America. Neither has resulted in a meaningful resolution. Hyundai's internal "acceptable" oil consumption threshold of 1 quart per 1,000 miles is significantly outside mainstream industry standards set by other major manufacturers and appears designed to deny warranty claims rather than protect consumers. This defect poses a direct and serious safety risk. A vehicle stalling on the interstate due to oil starvation, with no warning to the driver, is a life-threatening failure. I am requesting that NHTSA open a formal investigation into the 2020 Hyundai Palisade for excessive oil consumption and oil pressure warning system failure.

Hyundai's recent emissions software update (9c9) has disabled engine braking, creating a risk of brake fade on grades. The vehicle is no longer able to hold speed while descending grades, regardless of downshifting, forcing the brakes to be implemented to avoid excessive speed. This was never an issue prior to the software update and happened immediately after the software was installed. Instead of holding the vehicle with the engine (foot off the gas, and downshifting) the engine will continue to increase speed up to the point of approaching maximum rpms. Further evidence of this behavior is that trying to use the engine braking no longer shows maximum mpg on the dash, indicating the software update is still feeding fuel to the engine with the foot off the gas.

I am reporting a safety concern involving my 2026 Hyundai Palisade limited involving repeated engine malfunction warning lights and diagnostic trouble code p001600 (camshaft/crankshaft timing correlation fault). This issue has occurred multiple times within the first 60 days of ownership and the vehicle has been taken to a Hyundai dealership twice. The dealer has not been able to determine a permanent repair and states the code is stored as a history fault without an available fix at this time. This defect is concerning because camshaft/crankshaft timing correlation faults can potentially result in engine stall, loss of power, or unexpected shutdown while driving, which could create a serious safety risk. I routinely drive long distances and transport two small children in this vehicle and no longer feel confident in the safety and reliability of this vehicle due to the unresolved engine defect. Additionally, I understand there is a recent safety recall affecting certain 2026 Hyundai Palisade vehicles, which increases my concern about the safety of this vehicle platform. I am submitting this complaint because this appears to be a potential safety defect involving engine operation that could affect safe driving conditions.

Vehicle is consuming or burning oil at a high rate. While dealer has done an oil consumption test and claimed it was "within tolerance," I have on multiple occasions had the car start to shudder at 2,000 miles since last oil change only to find the oil wasn't even on the stick anymore. The symptoms go away when adding oil, on some occasions more than 4 quarts of oil need to be added to get the oil to "full" on the dip stick. Multiple independent service centers have noted how dirty the oil is and how little is drained on oil change. No warning lights have come on at any time, even when car is making grinding noises and shuddering with no oil. This causes a safety issue as drivers reasonably expect to go at least 3,000 miles between oil changes and the engine could seize in traffic. Owners are being tacitly asked to add oil regularly to keep the engine functioning properly.

The contact owns a 2020 Hyundai Palisade. The contact stated that the vehicle was consuming an excessive amount of oil. There was an oil-burning odor coming from the vehicle. There was a misfire coming from the engine before the vehicle stalled. The auto start/stop was activated while driving. The feature was turned off, but quickly reactivated. There were no warning lights illuminated. The vehicle was taken to the local dealer, who was unable to determine the cause of the failure. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 89,000.

Description of incidentthe vehicle experienced a severe engine system defect and catastrophic internal mechanical failure. The primary symptom prior to the failure was excessive, rapid engine oil consumption between scheduled maintenance windows. The issue was officially confirmed by an authorized dealership service center, where diagnostic testing verified that the engine has critically low cylinder compression in cylinder 1. The vehicle is currently completely incapacitated, and the disassembled engine block remains at the dealership facility available for inspection upon request. Safety risk assessmenta sudden and severe loss of internal engine cylinder compression creates a critical vehicle performance defect, an immediate stall risk, and a catastrophic hazard when operating on high-speed roadways. In this instance, the mechanical failure completely disabled the household’s primary, medically modified means of transport. Because the manufacturer and dealership failed to maintain or provide a structurally or layout-compliant alternative vehicle, a permanently disabled occupant was forced into a tight, non-accommodated cabin geometry. This directly induced severe physical trauma, muscle spasms, and an immediate loss of lower extremity neurological sensation while operating the replacement vehicle. The combination of a catastrophic powertrain failure and a total refusal by the dealer and manufacturer to provide an accessible replacement layout has completely stripped a vulnerable consumer of independent mobility and created a severe, ongoing physical safety hazard.

This vehicle is still using the defective style piston rings causing oil consumption of 1. 5qts in 1000miles, with only 100,000miles. This has been ongoing since we purchased the vehicle with 94,000 miles. This needs to be issued as a recall to replace piston rings or the engine entirely. My valuemax level 4 extended warranty is refusing to repair the issue stating Hyundai/kia has carbon buildup on the piston rings. This engine could run low on oil and cause a fire, or a engine shut down causing a crash.

The engine in my 2021 Hyundai Palisade experienced sudden loss of oil leading to engine failure. The vehicle had been regularly serviced and maintained at a Hyundai dealership according to recommended intervals. During multiple service visits, the dealership informed me the vehicle was low on oil. An oil consumption test was performed but the results were inconclusive. At approximately 99,500 miles, the vehicle developed an oil leak which the dealership diagnosed as a gasket issue and repaired under warranty. An oil change was completed at that time. Approximately 5,000 miles later, while driving, the vehicle began experiencing loss of power and rough engine operation. I immediately drove the vehicle to the dealership. The dealership later informed me the engine had no oil in it when inspected. There were no active external leaks observed at that time. The dealership stated that it is “normal” for this engine to consume up to one quart of oil per 1,000 miles. The engine now requires full replacement due to internal damage caused by oil loss. This situation created a safety concern because the vehicle began losing power while in operation. The failure occurred suddenly without warning indicators prior to the loss of engine performance. The vehicle had documented oil level concerns during previous service visits, suggesting a potential excessive oil consumption or engine defect. The failed engine is currently available for inspection at the dealership.

The contact owns a 2026 Hyundai Palisade. The contact stated that the vehicle turned off on several occasions after the engine auto start/stop system was engaged. The vehicle was restarted and was taken to the dealer; however, the failure could not be duplicated. Additionally, upon starting the vehicle after the vehicle was refueled at a gas station, the check engine and several other unknown warning lights were illuminated, and the vehicle failed to respond while shifted to drive(d). The vehicle was towed to the contact's business. The vehicle was then towed to the dealer; however, the vehicle was not diagnosed because there was no warning light illuminated. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was 5,463.

My car is consuming too much oil. I am going through almost 2 qts per 1,000 miles. Combustion cleaning and consumption test have been completed with no fix to the problem.
