general problems of the 2020 Hyundai Palisade - part 1

When attempting to use engine braking to control descent on mountain roads, the vehicle failed to slow. Engine rpms increased and speed increased requiring significant brake usage. Last year the vehicle performed as expected as deceleration was controlled via downshifting with much less brake usage. The only change was the application earlier this year of Hyundai service campaign 9c9.

My properly maintained 2020 Hyundai Palisade suffered catastrophic engine failure at 77,000 miles. Importantly, prior to the engine failure, no check engine lights, low oil warnings, or other warning indicators were active or displayed. The vehicle gave no indication of an imminent catastrophic engine failure or lack of oil. In researching this matter, I have found numerous reports, as well as active and settled litigation, involving Hyundai engine failures and oil consumption concerns. Severe oil starvation due to engine manufacture issues caused a thrown rod which can result in fire. The car was being driven by my teenage son after dark and the engine completely shut down putting him in harm's way in the middle of the road. Hyundai has repeatedly refused my requests for assistance in repairing this known issue due to my being a second owner with a lesser warranty that is given to 1st owners. This issue is a safety concern and a known issue to hca and should be a recall to insure it stops happening.

Cylinder 1 and 6 rod bearing failure, plus complete destruction of piston number 6. On highway engine failed, sudden loss of power to move vehicle.

The engine burns oil excessively and the oil light does not come on when the oil is low. Our car is right at 90k miles, it began to shudder and malfunction out of the blue while we were driving on the highway. There was absolutely no indication the oil was low. Now the car will not turn on at all. We were in between oil changes. The safety of myself and my family was put at risk because the engine blew with no warning. The vehicle has been serviced repeatedly by Hyundai for this issue, and they are trying to tell us that it is normal for oil to completely burn out in between oil changes.

Premature engine fail. Excessive oil consumption due to piston ring failure. Maintenance has been done on car on regular basis. No check engine light. Carson was services at dealership 4 months ago.

Driving down road in early afternoon at about 35 mph. Car began to run rough (jutter) then almost immediately stalled. The car’s engine icon appeared on the screen along with verbiage indicating service engine soon. After about 3-5 minutes, I started the car and drove it directly into a parking lot approximately 100 feet from where the car stalled. I had the car towed to a repair shop in town. The following day the service adviser called after doing diagnostics and indicated the car had no oil (it was approximately 3,400 miles since my last oil change). The technician explained there were some minute cracks in the oil filter cap but nothing that would warrant such a large loss of oil. An oil change was done, the oil filter cap was replaced with an aftermarket cap, and the car was returned to me. I have contacted the service department of the Hyundai dealership where the car was purchased and am awaiting a call back.

I recently purchased this vehicle, and shortly after, it began having serious powertrain issues. When I accelerate, the vehicle intermittently loses power and starts shaking violently. It feels like the engine or transmission is slipping or failing. The rpms surge and drop rapidly, and the vehicle hesitates, jerks, and sometimes briefly slows down before suddenly accelerating again. This creates an unsafe and unpredictable driving condition, especially when merging or driving in traffic. I’m concerned about a loss of propulsion while the vehicle is in motion. My mechanic indicated the issue may involve the torque converter clutch not engaging properly (possible “stuck off” or circuit performance issue), which would explain the shuddering and inconsistent power transfer. Despite how severe this is, there are no warning lights or check engine light, and no diagnostic codes, which raises concern that the failure is not being detected by the vehicle’s onboard systems. I am also experiencing low and fluctuating engine oil levels even after topping it off and a recent oil change, which may indicate an additional engine-related defect. The vehicle has a clean title and no accident history. - failed system: powertrain (engine/transmission), suspected torque converter clutch malfunction. Vehicle is available for inspection. - safety risk: intermittent loss of power, hesitation, and surging creates a high risk of collision, especially in traffic or at highway speeds. - confirmation: my independent mechanic has identified as likely a torque converter related issue. - inspection status: not yet inspected by manufacturer or insurance. - warnings/symptoms: no warning lights or codes. Symptoms began shortly after I purchased and have worsened over time.

Excessive oil consumption - Hyundai is refusing to issue a recall even tho there was a class action lawsuit.

Component: engine my 2020 Hyundai Palisade (approximately 155,856 miles) experienced a serious and dangerous engine-related failure that resulted in a vehicle fire. My 16 year old daughter was driving alone at the time of the catastrophic failure and fire. For approximately six 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 driving, the vehicle suddenly developed a new oil leak, and the engine failed without warning, leaving me 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 155,856 miles no prior accident or external cause contributed to the fire.

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).

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!.

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.

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.

While idling at a traffic light on a busy city street all of the warning lights on the car went off and the car shut off on its own.

I am reporting a safety concern involving repeated engine stalling while driving my 2020 Hyundai Palisade. The vehicle has stalled a total of seven times during normal operation. Most of the incidents occurred while slowing down or stopped at intersections and traffic lights. In these situations, the engine suddenly shut off without warning. I was forced to immediately shift the vehicle into park and restart the engine to continue driving. The check engine light did illuminate in connection with this issue. These incidents create a serious safety hazard, as sudden engine shutdown in active traffic increases the risk of rear-end collision. The loss of engine power occurs unexpectedly and without sufficient warning. The vehicle has been inspected, and I was informed that the issue may involve internal engine malfunction requiring major repairs. Because this vehicle has experienced multiple unexpected stalls in traffic, I am submitting this complaint due to the significant safety risk posed by sudden engine failure during operation.

Dear NHTSA, I'm reporting a serious safety issue with my 2020 Hyundai Palisade (3. 8l v6) involving excessive oil consumption without low-oil warning lights. Timeline: oil changed: August 13, 2025 ? engine stalling/rough idle ? checked oct 27, 2025: completely out of oil oil changed again: October 27, 2025 ? same symptoms recur ? January 16, 2026: completely out of oil again usage: ~300 miles/week (1,200 miles/4 months) using full synthetic 5w-30—far below Hyundai's 7,500-10,000 mile interval. Safety risk: no low oil warning despite total depletion x2, risking catastrophic engine failure while driving. Known lambda ii v6 issue per TSB 20-01-0001. Request: investigation into oil consumption recall and sensor failure.

Check engine light came on and stayed on. When using heat for car it was not heating up well or to temp. Got in to be serviced 12/16/25-12/18/25. Replaced a plastic part in engine and said engine was not heating up like it should. Cost $814. Reset check engine light. On 1/2/26 reversed car out of driveway into street and car came to abrupt stop and would not shift into any other gears. Another vehicle was coming up the street and almost collided with us and I could not get my vehicle to move which was blocking the road. Warning message said “shifter system malfunction: service immediately. ” pushed power button to turn off vehicle. Turned back on and able to get into drive to park back in driveway. Definitely having electrical issues and multiple problems with car since October 2025 when weather became colder for winter.

Engine started burning oil at around 70,000 miles. It now runs almost completely out of oil at around 5,000 miles since last oil change, not even close to reaching the manufacturer recommended interval of 7500 miles between oil changes. On top of the engine consuming oil at an alarming rate, there are no warning indicator lights that turn on to let you know your oil level is critically low. At around 74,000 miles?, Hyundai did a combustion cleaning. I've had two oil changes and it was back to vibrating, knocking, shifting hard, etc, right before a 3rd one at 5,300 miles since the last one and it stalled. The vehicle has now stalled twice, all engine lights flashed, then car stalled. Thankfully, this was not on an interstate or major road. This is a major problem!.

The weather became cold outside. After first frost overnight, an oil leak started underneath the hood next to the front passenger side tire. Got in be serviced 11/19. Told the plastic piece to oil housing assembly cracked and had 9 other Palisades in for same exact issue. No warning lamps. Cost $519 to replace part.

I am the 3rd time owner of this Palisade. Car was bought after a transmission replacement at 27,000 miles. (second transmission). At around 70,000 miles, we started to have oil consumption problems/ignition coil problems. After a slew of tests and other recommend procedures that cost us money out of pocket, Hyundai recommended to get a new engine. We get the new engine. They call to tell us the new engine is done, and proceed to share the transmission is bad and it needs a new one (3rd transmission). They are asking us to pay for the transmission as well. We want a buy back as we think this is a lemon car. 3 transmissions and a new engine under 85000 miles is not good and definitely grounds for investigation. These repeated failures make it unsafe/unreliable for us to drive our 6 month old baby in, let alone my wife and my myself. . We request and investigation/buyback.

On roadtrip with family to daughter’s soccer tournament. Car started to shift funny then engine light turned on along with warning display saying something was wrong with the engine. We were only hour into driving so drove hour back home to dealership/service for Hyundai. They looked over the car and reported that we did the right thing by bringing it back and not continuing our roadtrip with it. The thermostat wasn’t working which would cause issues to engine with overheating and putting my family at risk with driving it on road trip with engine overheating.

The vehicle suffers from a severe manufacturing defect causing excessive engine oil consumption (burning more than 2+ quarts per 1,000 miles) with no warning lights or oil pressure indicators activating. With little to no warning, I could be driving and experience catastrophic engine failure. This defect creates an immediate safety hazard, as sudden engine seizure or stalling at highway speeds risks loss of power braking and steering, creating an imminent risk of a high-speed collision. The dealership has confirmed the oil consumption issue after we noticed the vehicle stalling and performing sluggishly until the oil was changed.

Engine stall from excessive oil consumption. Oil and engine light not turning on prior to stall.

Vehicle started rattling at 96k miles with no check engine light. Performed diagnostics and found that the vehicle had zero oil inside. Determined that there was no sign of an oil leak and that the engine had internally consumed all of the oil. The rattling still exists and when reported to Hyundai, they sent me away and said to come back after 1k miles to see if it’s consumed 1. 1 quarts and only then they will clean the engine and see if that helps and if after another 1,000 miles I still am consuming oil, they will replace the engine. They are refusing to provide a loaner vehicle throughout this process as well.

On xxx I took my vehicle to ourisman Hyundai of bowie because my engine light was on. That same day the service adviser (edson xxx) informed me that the engine was burning oil excessively. They performed an oil change and replaced engine oil gasket and asked me to return after driving 1000 miles. Mileage at the time was 103,380. I return on xxx, mileage was 104,580. [xxx] informed me that vehicle failed oil consumption test. He submitted request for engine replacement. On 11/25/2025 I returned to dealer because engine light came on again, and still no approval for engine replacement. I was informed that Hyundai approved combustion chamber cleaning. The service was complete four days later. However, it did not fix the problem. The engine excessive oil burn still happens as of this report. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Twice the engine oil consumption was bone dry. No warning lights or oil leaks on the driveway were seen. The engine without oil was subject to destruction . We replaced the oil twice - with documentation . Oil changes were made within 6 months since we purchased the car ( documentation was given ). It is known that specific models were affected by a bad engine that was installed ! Hyundai has offered nothing but aggravation even though it is known that there is a problem with specific engines that were put into the 2020 Hyundai Palisade .

Our motor has been consuming a lot of oil, we were told that Hyundai knows about the issue and that there is nothing they can do. We got sold a poor excuse of a warranty in which they never told us that the warranty would not cover oil consumption, but we have the “best” warranty they had. Our car has died going down the road with my 4 kids and wife! cars had to swerve to avoid a collision, 5 times this has happened but yet they will not do anything! we will be seeking legal help!.

The contact owns a 2020 Hyundai Palisade. The contact received notification of NHTSA campaign number: 26v034000 (air bags) and 25v607000 (seat belts); however, the parts for the repairs were unavailable. The contact stated that the manufacturer had exceeded a reasonable timeframe for the remedies to be available. The contact stated that when driving at various speeds and while idle, the vehicle would shake. The contact had checked oil levels and noticed that there was no oil in the vehicle. The contact had to begin changing the oil every 1,000 miles. The contact looked up the carfax and learned that the vehicle had a history of oil consumption issues. The vehicle was taken to the dealer, who confirmed that the remedies were not available and then diagnosed an oil consumption failure. The dealer completed an oil consumption and cleaning and advised them to drive 1,000 miles to receive assistance for the engine, as it was at risk of seizing. The vehicle was not repaired. The manufacturer was informed of the failure. The manufacturer informed the contact that the failure was not covered by recall or warranty. The failure mileage was approximately 83,000.

Many Palisade owners and I have a same issue that the vehicle shaking when applying the brake the the car slipping jerking forward. That is really unsafe for us. Please review this case.

2020 Hyundai Palisade, VIN: [xxx] . Excessive engine oil consumption beginning at ~95,418 miles. Oil drops to critical levels between oil changes, causing engine hesitation, rough running, and check engine light activation — cel clears only after oil is manually added, confirming oil starvation as the cause. Safety risks: engine seizure or stall at highway speed; engine fire from oil burning on hot components; sudden loss of vehicle control; cel only illuminates after oil is already critical, leaving no safe warning window. Dealer: vehicle brought to dealership in [xxx] on 8/25/25 (95,451 mi) and barnes crossing Hyundai, [xxx] on 4/22/26 (99,969 mi). Ro# xxx/1. Hma case# xxx. Both dealers confirmed abnormal oil consumption. Manufacturer response: Hyundai motor America denied all repair or engine replacement solely because the title was transferred from a family member. Hyundai's own xxx (Dec. 2023) acknowledges systemic oil consumption across all Hyundai gasoline engines and mandates a repair protocol including engine replacement. A title transfer does not cause a mechanical defect and Hyundai failed to apply its own TSB procedures before denial. Requested action: investigate hma's pattern of denying txxx remedies after title transfers; compel engine repair/replacement at no cost; evaluate safety recall eligibility.
