general problems of the 2021 Hyundai Palisade - part 1

The engine oil system failed due to a persistent oil leak that was present from the time of purchase on December 16th 2024. The vehicle is available for inspection upon request and is currently immobile due to a completely seized engine. My safety was put at serious risk because the vehicle has no functioning low oil warning indicator to alert the driver of critically low oil levels. I was driving this vehicle regularly for work with no indication whatsoever that the engine was losing oil. A seized engine can cause sudden and complete loss of vehicle control which puts not only the driver but other drivers and pedestrians at risk. This failure occurred without any warning while the vehicle was in regular use. The oil leak was brought to the selling dealership, auto merchants inc. In plano texas, for repair on January 6th 2026. They kept the vehicle overnight and confirmed it was fixed. The problem was not resolved as the vehicle continued losing oil. On March 3rd 2026 I discovered the engine was completely empty and added 6 full quarts of oil with no warning light appearing. I also contacted Hyundai consumer affairs and the Hyundai dealership directly who confirmed the manufacturer warranty had already expired at the time of purchase on December 16th 2024 and declined to cover the repair. The vehicle has not yet been formally inspected by the manufacturer or insurance representatives. The dealership serviced it on January 6th 2026 and claimed the leak was repaired however the engine seized on April 20th 2026 due to continued oil loss. There were zero warning lamps or indicators of any kind prior to the engine seizing completely on April 20th 2026. No low oil warning light appeared at any point during the 4 months I owned this vehicle despite the engine running completely out of oil on three separate occasions. The only symptom prior to full engine seizure was the vehicle sputtering when coming to a stop on April 19th 2026, one day before the engine seized completely.

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.

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.

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.

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. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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.

Oil filter housing leak. Does not impact oil levels but more notable during cold weather as the ring tends to shrink.

The engine is burning oil at a rapid rate. It's burning one liter every 70 miles.

Excessive oil consumption. The vehicle is burning nearly 4 quarts of oil between changes. This started at around 100,000 miles with no warning lights. The only indication was a strange tapping noise coming from the engine.

Vehicle experienced engine failure previously and received a Hyundai-installed replacement engine in February 2025. Replacement engine is now setting dtc p000a00 – intake camshaft position slow response (bank 1). Hyundai dealership master technician confirmed excessive variance between commanded and actual cam timing, indicating a vvt / cam timing failure controlled by oil and actuators. Hyundai is refusing to cover diagnosis and repair under replacement engine warranty and is requiring customer-paid tear-down despite fault originating within the engine assembly. Concern is for internal engine timing failure that may lead to engine damage or loss of power. This appears consistent with known Hyundai engine timing and oil control issues.

I bought my vehicle almost 2 years ago with 30k miles on it. In December 2025, the car started stalling and wouldn’t run properly. I took it into the dealership and they stated that the engine was burning oil. This was at 90k miles. Hyundai refuses to fix the motor issue because I’m not the original owner. This issue would have started even before the 90k miles because the vehicle had almost used all its oil in between the normal oil change interval. They did a sludge clean and we checked the oil again after 1500 miles and it had already used over a quart of oil.

My vehicle experienced a sudden and immediate loss of motive power due to a catastrophic internal engine failure, creating a severe road safety hazard. While driving and attempting to accelerate or merge, the vehicle exhibits extreme hesitation, severe misfiring on cylinder #2, and rough, unstable idling. This unexpected loss of drive power made the vehicle unpredictable and unsafe to operate under normal driving conditions, significantly increasing the risk of a crash. The vehicle is currently at the Hyundai dealership (fox ann arbor Hyundai) for diagnosis. The dealer has confirmed and documented the following internal mechanical defects at only 86,000 miles: compression loss in cylinder #2. Cylinder wall scoring and pitting. Evidence of blow-by and heavy carbon buildup in the combustion chamber. Misfire and rough idle. Oil consumption as a result of the cylinder failure. This failure is a premature mechanical defect, not normal wear. Failures of this nature (sudden loss of motive power due to internal engine defect) have been cited by NHTSA in other recalls and are known to increase the risk of a crash or fire. The manufacturer has acknowledged the defect by offering only 50% goodwill toward a repair, but this defect remains a critical, unresolved safety hazard that requires a full, safe engine replacement. ".

I own a 2021 Hyundai Palisade calligraphy with approximately 114,000 miles. The transmission had to be replaced at around 98,000 miles. Recently, before my next scheduled oil change (I had about 1,000 miles left), my vehicle suddenly began making a loud knocking noise and lost power. The dealer informed me that the engine may have blown. There were no warning lights, oil indicators, or overheating signs before this happened. The car has been regularly maintained and serviced with timely oil changes. This appears to be a premature engine failure possibly related to oil consumption or an internal defect, as many other Palisade owners have reported similar issues. Hyundai consumer affairs has been contacted, and a case number is being opened for review. I am filing this complaint to report a potential widespread engine problem and request investigation into 2021 Hyundai Palisade engine reliability and oil-related failures.

The engine failed due to oil consumption. The engine burns to much oil. It burns more oil than it holds during normal intervals between changes. It also did not give any oil lights or engine lights on the dash (not one indicator came on). When we took it in the service advisor told us the computer had indicated a problem, but that was for the technician.

I started smelling coolant fumes in my vehicle. Upon inspecting the coolant reservoir, I noticed it was empty. Upon inspecting the radiator itself, I noticed that some of the coolant was leaking. Fumes associated with the leaked liquid touching hot parts in the engine were entering the vehicle cabin. I noticed there was a technical bulletin regarding this issue for Hyundai Palisades. I informed the dealer as well as Hyundai corporate. Despite the technical bulletin, both entities ignored my issue and said it was not covered under warranty. In addition to potentially impacting the engine (if the coolant runs out), I believe the fumes are toxic and pose a serious health risk to passengers. As this seems to be a well known problem, I believe it needs to result in a recall (and not a technical bulletin).

While driving after owning the car for only 2 months and before the next oil change was dure the car started surging and then died when turning a corner. No check engine light or any warning or error lights triggered on the car. The car was restarted and limped home slowly about 2 min from where I'd shut off. The hood was opened and oil lipstick checked to find no oil in the vehicle. Not oil leaks anywhere, no check oil or engine light and no error codes found by dealership. The dealership confirmed no oil leak and consumption issue, oil change done and have to return in another month to jump through hoops to get engine repaired as this is a consumption issue not a leak issue. Dealership is playing games with us around this and trying to get out of repairing the car. But internal engine issue was confirmed. Vehicle returned to us unrepaired to drive for 1000 miles and return for further review even though the issue was confirmed. This is a safety risk to me, and others on the road. Hyundai of union county is the dealership playing games in getting this repaired. ,.

Oil consumption- oil is being consumed at a rapid rate. Even when there is no oil in the vehicle, there are no lights that show up to signify low/empty oil. Once the oil is run dry, the car begins to make noises, can not accelerate, and jolts while driving. Oil must be checked every 2,000 miles.

The engine has been intermittently cutting off every day. We have taken it to the dealership multiple times, and they say they cannot recreate the issue, so there is absolutely nothing that they can do. The vehicle will shake a little bit and then turn off.

This car is consuming oil rapidly. I checked oil level to and had no oil on dip stick the car has not bee inspected yet. No warning lamps came on to warn me of low oil.

The contact owns a 2021 Hyundai Palisade. The contact stated while driving 30 mph and depressing the accelerator pedal, the vehicle lost motive power. Several unknown warning lights were illuminated. The vehicle was taken to the dealer to where it was diagnosed and determined that the engine needed to be replaced due to excessive oil consumption. The contact stated that the failure had occurred on several occasions the vehicle was not repaired. The manufacturer was notified on the failure but offered no assistance. The approximate failure mileage was 107,000.

My vehicle is using too much oil. I was between oil changes and my car did a safety shut down while I was driving on the busy highway with my grandchildren and left me like a sitting duck. I was finally able to get it off the middle of the highway by restarting the vehicle. My engine light was lit up. I parked it for 15 minutes and then restarted it and traveled the 40miles to home. The next day I took it to our local mechanic and he ran the code and it shut down for safety due to no oil in the vehicle. He added 4 quarts for me. 96033 was the mileage showing on my sticker for when the next oil change was due. My current mileage showed 94743 showing I still had 1290 miles before my next oil change was due. I have always used swope Hyundai in elizabethtown, ky for my vehicle service. I called and scheduled an oil consumption test. I did what they said and they said that it was an acceptable amount of oil loss per Hyundai standards. I am still over 1000 miles away from needing my oil change and my husband has been checking my oil for me about every 1000 miles. He stated that he has put in 5 quarts of oil in my vehicle since my last oil change. If he had not done this then I would have been left in a terrible situation again out on the road endangered of being crushed by semi trucks etc. When my vehicle would have shut down again for safety reasons to protect the engine. Why am I paying over 800 per month on a vehicle that is burning oil, I cannot trust and I work out of town 80 mile round trip and mane numerous trips to town for my grandchildren's activities. I need answers to this problem with immediate solutions. I love my vehicle but I do not love this oil consumption issue. I have researched and I do see that many of this type of vehicles both Hyundai and kia have had issues.

Engine is consuming too much oil causing oil light to come on and it continues to happen.

We have brought the vehicle to potamkin Hyundai on three separate occasions, [xxx] [xx], and [xxx], and [xxx] due to the engine stalling unexpectedly while driving. This issue has placed our family, including our children, in serious danger and has not been resolved. At our initial visits, we were informed that the engine was consuming excessive oil. However, during our most recent visit on August 5, 2025, we were told that the engine was full of oil and functioning properly, and that no error codes were present. Because they were unable to duplicate the issue, we were told we would need to pay out of pocket to tear down an already faulty engine which is unacceptable. Despite this, the vehicle shut off once again while driving, creating a hazardous situation that is completely unacceptable and life-threatening.

My 2021 Hyundai Palisade has had some issues relating to the engine recently. We take extremely good care of our cars, and are early when due for our oil changes. A couple of months ago, my husband checked my Palisade's oil before a trip. There was no oil showing on the dip stick! I had just gotten an oil change 2000 miles before. He added 6 quarts of oil, and it was still only showing half full. We brought it up to the dealer, and they did an oil change and $900 worth of replacing things that were not covered on the extended warranty. Last month, I drove it, and the engine light went on again. We brought it in, and they said there was no oil? we told them it is not leaking anywhere, but it might be burning off or slipping somewhere else. They did an oil change (which we had to pay for even though there was no oil) and told us to come back in 1,000 miles. We went back and they said it was burning over a half quart after 1,000 miles, but Hyundai won't do anything unless it burns more than 1 quart in that time. Then, 3 days later, my engine light comes back on, and here we are again. No oil, not even 1,500 miles, and at the dealership again a week later! this time, they are doing a combustion chamber cleaning? I understand there are procedures that need to happen, but this does not fix that my engine is burning my oil. 3 of my coworkers have had their engines replaced due to this issue of oil consumption and where it goes. This can cause my car to die on the side of the road, immediately, and combust! my family is at risk of being in the car, and so are others who drive around me if this happens. Why is Hyundai waiting for this to happen? this is completely negligent on their end!.

We have been in Hyundai’s “oil consumption” protocol for the past 8-10 months. We’ve had 6 oil changes in that time. Each oil change was right a 1,000 miles. My engine is burning between 1. 5 - 2. 5 quarts of oil every 1,000 miles. They have been trying to drag this out not having to take ownership of the issue. After reading online, clearly there is an issue with 2021 Palisades and a recall needs to be issued.

The engine consumes oil at an unsustainable rate without any visible leaks or warning signs, leading to a complete engine failure.

Engine burning 6qts in less than 3k miles of driving. Aside from that, the engine light does not always illuminate to tell me it is low. Now I watch monthly and add oil as needed.

The issue is with excessive oil consumption, unknown, SUV was taken to the dealership and that's when I was told what the issue was, just inspected by the dealership, warning was the truck was shaking abnormally.

The car will start shaking, can’t exceed a certain mpg, and does not speed up. The check engine light comes on. The car is available for inspection. I drive on the freeway and slowing down, and shaking can cause accidents. This a continuous problem.

Engine consuming way to much oil. Did oil consumption test and it is going through a quart and half every 800 miles. Dealership is dragging there feet on getting this taken care. They put a solution in to see if that would fix it. Now it is eating oil more I have to put two quarts of oil in every week. There is no low oil indicator on this vehicle which is terrible so you have to check it or pay attention to the noise. The car runs so rough when it is low a quart and sometimes the engine stutters.

On expressway traveling through atlanta, changing lanes with plenty of clearence using signal at approximately 55 mph when suddenly alarm sounded and breaking system engaged bringing car to almost complete stop. Could not accelerate and fortunately made it to berm area without causing serious accident. Turned engine off and restarted vehicle and continued on my way. Had vehicle checked at dealership and they said “all checked out and we found no diagnostics problem”. Also weren’t able to duplicate incident. I hope to god I am unable to duplicate the incident and cause fatalities including myself.

I have a Hyundai Palisade complaint. Nhtsa id number: 11613395. I was trying to add additional information. The car stopped working again. It stops at intersections and won't start up. This time it wouldn't start at all. Had to be towed to the nearest Hyundai dealership. Since June this car has been at the Hyundai service center. The following parts have been replace. Transmission front axle bearing kit 3 ignition coils 5 spark plugs this time they are saying the reason the car stops and won't start is the "starter" needs to be replaced. Out of 6 months, this car has been at the service center for 3 months and multiple visits to the servcie center and three major repairs for the same issue. I want to know if others a having the same issues.

Sputtering when it is stopped and driving. It then cut off when stopped at a light multiple times and check engine light came on.

Paint started chipping… dealer stated it was from a rock, however a rock chip doesn’t cause a whole section of paint bigger than a quarter to just flake off. . Ironically there was another vehicle on the lot having the same issues . Picture is included. . Second issue is the engine it makes a grinding noise when driving almost like the cams or transmission is going to go bad, but I think it’s the timing chain. Lasty the suspension it has clicking noises that cannot be resolved.
