general problems of the 2021 Hyundai Palisade - part 1

Vehicle information: 2021 Hyundai Palisade limited (3. 8l v6 engine) complaint description: while driving at highway speeds, the vehicle suddenly began making a loud engine knocking noise, followed immediately by a total and catastrophic structural failure of the engine. A connecting rod bearing seized and the rod broke, punching a hole directly through the metal engine block. This mechanical failure caused an immediate, complete loss of motive power and propulsion while traveling in high-speed highway traffic. The sudden loss of engine power simultaneously disabled the power steering and power braking assistance, creating an extreme and immediate safety hazard as I was forced to navigate a completely dead, non-responsive vehicle across multiple active lanes of traffic to reach the shoulder. The vehicle was manually pushed directly to a licensed Hyundai dealership 1/2 a mile, where technicians confirmed a catastrophic internal engine failure with a thrown rod through the engine block. The vehicle had a consistent and documented maintenance history prior to the incident. No warning lights or oil pressure indicators illuminated on the dashboard prior to the sudden knocking and immediate engine destruction. This defect poses a severe, life-threatening safety risk due to the sudden loss of vehicle control on public highways.

Due to a known oil consumption issue the manufacture replaced the engine using a short block swap, they used the old fuel injectors and during the swap one of them failed, becoming stuck open. Now they refuse to fix it without me paying for labor. The failed fuel injector occurred immediately following a mandatory manufacturer engine replacement and poses a thermal/fire hazard.

I have been dealing with the oil consumption issues for this vehicle for about 2 years now. There are documented complaints and a class action lawsuit in California about this issue. Bottom line, the engine burns too much oil to be safely driven between oil changes without the owner checking and adding oil. My particular vehicle is burning just under 1 quart of oil per 1000 miles. Hyundai’s owner manual suggests changing the oil every 7,500 miles, but the oil capacity is under 6 quarts. At the current rate, I would run out of oil before the suggested oil change interval. This is a severe safety issue as engines require oil to run correctly, not overheat, and lubricate all the moving parts. The previous generation Hyundai models also had similar oil consumption issues. Those vehicles had a NHTSA campaign which resulted in Hyundai being responsible to fix the engines. I believe a recall is proper given the safety concerns noted above. At a minimum, Hyundai should stand by their work and fix the issues as they arise.

In the past two weeks, our 2021 Hyundai Palisade has shut off completely when driving. It has around 110,000 miles on it and was just purchased used (second owner) three months ago. At that time, the dealership had to fix a leak in the engine and did a complete oil change. Based on internet searches, we just checked the oil dipstick and it is completely empty. We have not driven more than 3,000 miles since purchasing the vehicle and there is absolutely no oil left. Based on searches, it appears this is a fairly common, known issue and nothing is being done. It is incredibly dangerous that the car shut down while driving (on the highway, in the middle of a right-hand turn). Every single warning light lit up at once then the car completely shut off within a matter of seconds. Thankfully my husband was able to get to the side of the road and no accidents occurred, but this is terrifying and completely unacceptable. The car is going to be towed to the dealership to check for excessive oil consumption, but again, based on research, it appears that this is a known issue but Hyundai says it is "within acceptable limits. " please do something about this before someone is seriously injured or killed.

I had an oil change in Feb 2026 at 64000 miles. In June, I was driving the car and suddenly the car started jolting while I was idle and would turn off completely when I was stopped. This happened to me while driving on the freeway in traffic and also at a traffic light. I immediately went to the dealership and was told my car had no oil in it. Since the oil change I drove about 5900 miles. I was told there were no leaks so the issue was either the engine or that when I had the oil changed that they forgot to put the oil in. They advised to get an oil test. I drove 1000 miles and took the car back in today 8/11. I had the oil tested and I burned . 4 quarts in the 1000 miles which was under the standards of 1 quart per 1000 miles in order to get the issue fixed. I was told that I needed to check my oil and add oil to the car when needed. I left the dealership confused because I have had this car for over a year and never had an issue with the oil or oil levels. I never had any oil indicator on my dashboard to alert me of any issue. I called back the advisor asking more questions because I did not understand how my car burned through so much oil that it was malfunctioning. After being talked to like an idiot about how it is my responsibility to make sure my car has oil, I was finally told that this Palisade has a known issue for premature oil consumption once it hits 60000 miles. Then I was told there is no recall and the issue will only get worse and I have to wait till it hits 1 quart of oil burned in 1000 miles for anything to be done. I feel like this is extremely irresponsible of the company to know this issue exists with nothing being done or communicated to their customers and that it is a huge safety concern to not have any indication there is something wrong with the oil amount and my car could literally stop in the middle of the freeway. They are waiting to make the issue neglect from the customer so they are not held responsible for their vehicle's issue.

Excessive oil consumption. Oil tank empty at 3 oil changes. Car was stalling at stops. Oil was empty 5000 miles prior to next suggested oil change. No low oil indicator light alarm.

While driving down the freeway my first row sunroof exploded. Insurance wouldn’t cover it because it is a manufacturer defect, but Hyundai wouldn’t cover it because it “isn’t a manufacturer defect. ” the temperature outside when the sunroof exploded was 74 degrees and it was cloudy. Then less than 2 months later my engine got a rod knock even with oil changes every 5k miles. No warning signs for either and no lights on the dash. It just started when I started it to leave for work one morning.

I am reporting a potential safety defect involving my 2021 Hyundai Palisade calligraphy awd. The vehicle has experienced repeated engine and drivability problems and multiple breakdowns following replacement of the engine by Hyundai. The original engine developed excessive oil consumption and was ultimately replaced by Hyundai with a new engine. Following the engine replacement, the vehicle experienced numerous additional mechanical problems and repair attempts, including engine rattling/pinging, intake-manifold replacement, oil valve-seal replacement, multiple cylinder misfires, ignition-system problems and an ignition-coil failure. Most concerning are repeated incidents involving severe shaking/lurching, loss of engine power, stalling and failure to restart. During one incident following repairs, the vehicle ran extremely rough, stalled and would not restart after approximately 20 miles of driving and had to be towed back to the dealership. During another incident, the vehicle experienced heavy shaking on startup, stalled and had severely limited power. Diagnostic history showed misfires involving multiple cylinders. On June 29, 2026, at approximately 103,671 miles, I was driving at approximately 50 mph when the vehicle began to lurch and shake, lost power, stalled and would not restart. The vehicle had to be towed back to the Hyundai dealership. The unexpected loss of propulsion and stalling while traveling at approximately 50 mph created a serious safety concern because I could no longer rely upon the vehicle to maintain power in traffic. The dealership subsequently identified an ignition-coil short/failure and replaced an ignition coil. The vehicle has nevertheless continued to experience additional mechanical problems. The vehicle is currently again at the Hyundai dealership. It has generated diagnostic code p0430 for bank 2 catalyst efficiency below threshold, and Hyundai has recommended replacement of both catalytic converter/manifold assemblies. Th.

What component or system failed or malfunctioned, and is it available for inspection upon request? rear exhaust system how was your safety or the safety of others put at risk? fire hazard as it was similar to a blowtorch, melted several rear panels, lights and trim while driving. Has the problem been reproduced or confirmed by a dealer or independent service center? the dealership (elyria Hyundai) requested a PA from Hyundai and it was authorized, but am having a very difficult time getting reimbursed. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? I am not sure what the dealership did with the exhaust. At one point, I had requested to keep it for evidence. There are pictures. I suggested having the manufacturer look at it or at least Hyundai. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? there were no warnings. After a 2. 5 hr trip, we got out; my children noticed the trim sticking out and melted off the rear right bumper. It was extremely hot to touch and the panels were bulging out from their normal position.

I am the original owner of a 2021 Hyundai Palisade sel awd (74,225 miles) reporting repeated engine shutdowns in traffic, severe rough idling, and an unresolved safety concern. The problem began 06/17/2026. I first brought the vehicle to Hyundai on 06/27/2026 and have sought service approximately four times since June. Despite technicians stating they could not reproduce the issue, the engine stalled again on 07/18/2026 after I picked it up from service. The dealership also instructed me to complete a 1,000-mile oil consumption test. When I returned after 750 miles, I was told I had returned too early. The engine subsequently shut off twice on 09/05/2026. Documented incidents: 09/05, 1:53 engine shut off on mission college blvd. 09/05, 5:38 engine shut off on lucretia Ave. 09/30, 5:08 engine shut off at I-880 exit, great mall pkwy/tasman dr. 10/04, 11:35 engine stalled at capitol expressway/mclaughlin Ave. 10/04, 12:30 engine stalled at great oaks blvd/san ignacio Ave; check engine light illuminated. 10/11, 10:57 near-stall with severe rough idling at los gatos farmers market. After further rough idling, the check engine light remained illuminated. On 10/19/2026, the dealership service advisor personally experienced severe rough idling and an apparent near-stall while moving my vehicle, with the check engine light on. I heard her acknowledge the issue. The vehicle remains at the dealership. I provided a written incident log and opened Hyundai case #43408836. Repeated engine shutdowns at intersections and freeway exits pose a serious collision risk. I request NHTSA investigate this potential safety defect.

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.

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).

Whatever you do, do not purchase a Hyundai vehicle. Their engines are defective. On xxx, I brought my car in for service at castle Hyundai, [xxx]. I informed the service representative that I was having issues with my car stopping and automatically applying the braking system intermittently. They looked at the car and said they saw nothing was wrong. They charged me $940. 30 for diagnostics and replacing a couple of belts and oil filter housing leak. I started having the same issue in xxx and I brought my car in again. This time they told me that my car was burning oil internally and that I would have to have a combustion chamber cleaning. I was informed by the service manager that this was a common problem with my vehicles model year and that if was a requirement to for the warranty people to initiate changing the engine. I paid $1,094. 26 for this service. I was told to bring the car back after driving the car an additional 1,000 miles. I was also told by that service manager that his dealership changes about 200 engines a month due to this issue. I took the car back to the dealership after driving the 1,000 miles. I sent them photos of the 3 oil changes I could find documentation for, and I had one done at this dealership. I was informed by the dealership that the warranty company and Hyundai when asked, refused my claim. I called the warranty company myself and they would not uphold my claim. I then contacted the regional case manager, and they tried to tell me something different. They told me my car was over warranty and that the engine was only covered up to 60,000 miles. I have the warranty in my hand, and it says lifetime warranty. This is not fair. I am [xxx] old and I bought the car with 31,000 miles on the car. I have consistent and periodic oil changes but could not remember all the places. This is the first Hyundai I have purchased and I am asking that my claim be upheld and executed s information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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).

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.

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.

I have multiple recalls that have not been fixed that are safety issues this is disgraceful I would like help from a higher power than myself to get this sorted this is our family car shame on Hyundai.

My Hyundai Palisade was bought brand new in 2020. It currently has 131,500 miles on it. I noticed at around 110,000 miles that my oil was getting low before each oil change. I check my oil frequently. No oil leaks can be found. So the engine is burning oil somehow. My mechanic says Hyundai says its acceptable for it to burn oil after 100,000 miles but 2 quarts between oil changes seems excessive. Ive talked to other Palisade owners who have this year model and have the same issue. If I were not a responsible consumer and checked my oil as frequently as I do then its very possible another consumer could have burned their engine up before they knew what was happening because there is no leak just burning of the oil. This is very dangerous.

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.
