While driving, the vehicle intermittently loses engine power without warning. The loss of power occurs at normal driving speeds and during acceleration, creating an unsafe condition in traffic. When the issue occurs, the vehicle hesitates and fails to respond to throttle input, making it unsafe to merge or maintain speed. The condition occurs intermittently and does not consistently trigger warning lights or diagnostic trouble codes. Despite the absence of warning lights or stored codes, the loss of power is clearly felt while driving and presents a serious safety concern. The issue has occurred multiple times and has not been permanently resolved despite prior service visits. The intermittent nature of the failure and lack of codes makes diagnosis difficult, but the problem continues to recur and affects the safe operation of the vehicle. This loss of power creates a risk of stalling or sudden deceleration while driving, increasing the likelihood of a collision, especially in traffic or at intersections. The issue appears related to the engine timing or powertrain system.

My radiator is leaking

- Spartanburg, SC, USA

The engine is burning oil at a rate that is unreasonable. When the oil level is low, there is no oil light indicator to show that the car is low on oil. My safety is being put at risk because the engine could seize up at any moment and may have slow or no acceleration. I caught the low oil problem just in time because i have a child who was aware of what the issue was with the car. I have had normal oil changes. This is a known issue in Hyundai's and these vehicles need to be repaired/replaced. The care will be inspected by a Hyundai dealership.

After my 2022 Palisade Calligraphy with 95K miles stalled several times in intersections and ran rough, dealership said I was 4 quarts of oil low. Dealership recommended an oil consumption test and vehicle burns 1 quart every 568 miles. Hyundai denied my claim under their 100K power train warranty since I was 2nd owner, and they did not make a good will offer. After researching, it appears oil consumption is a common problem with Hyundai vehicles, specifically the Palisade. Aftermarket warranty I purchased denied my claim since it didn't cover oil consumption. Submitting this incident so others are aware of oil consumption issues with Hyundai vehicles as vehicle is unsafe when it stalls.

The oil filter housing is plastic and breaks easily. Most places I tried to get an oil change refuse to work on this car because they don-??t want to be liable for any damage to the engine do to a cracked oil filter housing. This is a know issue and the manufacturer has not issued a recall or offered a fix. This forces owners to bring there vehicles to a Hyundai dealership and pay a premium for an oil change.

My car was making a rattling noise from the engine and would stutter at a stop and sometimes kick into park or turn off. No warning lights would turn on, on the dash board warning i was low on oil. The back passenger brake light warning light turned on. The Third seat middle seatbelt does not lock. I took into Hyundai to get it serviced and I had to pay for my car to be put on a diagnostic test. I was told I was low on oil. I never had any warning lights go on, on my Dashboard. My motor could have blown out. The only warning light I got was my back light is out. I never had any warning signal go on my dashboard saying my seatbelt doesn-??t lock. I had it serviced 2025 and again the same back tail light is out. I have kept my vehicle maintenance up to date. I am going to have to schedule another appointment for my back tail light ( same side) to get repaired

My 2022 Hyundai Palisade has repeatedly shut off while coming to a stop. The vehicle stalls unexpectedly, dashboard lights illuminate as if the vehicle is being restarted, and the gear sometimes shifts into neutral. I have to manually restart the car to resume driving. This issue has occurred multiple times under normal driving conditions-?"both when the Idle Stop & Go (ISG) system is enabled and disabled. The frequency of these stalls has increased, and they present a dangerous situation, especially at intersections or during heavy traffic. After researching online, I found that numerous 2020-?"2022 Palisade owners have reported the same symptoms. Many of them were told by their dealers that an ECU and/or TCU software update was needed. This suggests a broader systemic issue with the vehicle-??s powertrain management system, which should warrant further investigation. As of now, no recall has been issued, but this is a recurring issue that poses a risk to driver and passenger safety. Hyundai has not officially acknowledged a recall or permanent fix, but affected vehicles are being patched with software updates at the dealer level.

The dealership is stating we have bad gas as the gravity of the gas was.74. And that we had bad fuel injectors. Mind you the dealership before this one advised us we had spark plug issues. So we called corporate and explained the situation and they advised we were covered under warranty. Now we tell them to go ahead and get rid of the bad gas and with the understanding we are covered under warranty for the fuel injectors. We advise the dealership we spoke to corporate and they advised the fuel injectors are covered under warranty. The weekend goes by we check on the car Monday and the dearlship advises we are not covered. So we call corporate back who is now advising it's up to the dealerships to honor the warranty and it looks like we are not covered. We are the original owners of the car and can't understand how our car has been down for 3 months and the person who makes the warranty want cover. This is the classic bait and switch and who protects the consumer?

I am writing to formally report a significant safety concern involving my 2022 Hyundai Palisade, specifically related to the radiator and coolant system. In November 2024, I experienced issues indicative of a coolant leak, including engine overheating warnings and noticeable coolant odors. Upon investigation, I discovered that Hyundai had issued Technical Service Bulletin (TSB) #23-EM-003H on August 3, 2023, acknowledging that certain 2020-?"2022 Palisade models may exhibit a slight coolant leak at the radiator. Despite this acknowledgment, Hyundai has not initiated a recall, leaving many consumers, including myself, vulnerable to potential engine damage and safety risks. ? Furthermore, numerous complaints have been filed by other 2022 Palisade owners reporting similar issues: -??One owner reported an engine overheat warning while parked, followed by a strong coolant smell and visible coolant leakage. The dealership diagnosed a cracked radiator. ? -??Another owner experienced coolant odor inside the vehicle and was informed by the dealer of tiny pinholes in the radiator, necessitating a replacement that was delayed due to high demand. ? These incidents highlight a pattern of radiator failures that pose a risk of engine overheating and potential safety hazards. The lack of a formal recall or widespread notification to owners exacerbates the issue, as many may be unaware of the potential danger. Given the severity and frequency of these problems, I urge the NHTSA to: 1.Initiate a formal investigation into the radiator and coolant system defects in 2020-?"2022 Hyundai Palisade models. 2.Assess whether Hyundai-??s current measures are sufficient to address the safety risks associated with these defects. 3.Consider mandating a recall to ensure affected vehicles are promptly and effectively repaired. I appreciate your attention to this matter and your commitment to vehicle safety.

While driving the car on highway the oil plug fell and eventually seized the engine. There has been multiple complaints for the same for other Hyundai vehicles as well. The car is in dealership right now with engine failure. While driving the car on I-81, suddenly smoke started coming out of hood. Stopped to check and then while starting the car again, saw oil check and engine check light come on after. The dealership mentioned oil plug fell off and oil spilled all over engine. The last service was over 7 months ago and was due for service soon. Couldn-??t be negligence but a problem with Hyundai.

I am writing to formally submit a complaint regarding multiple ongoing and serious issues with my 2022 Hyundai Palisade. These issues not only diminish the performance and reliability of the vehicle but also raise significant safety and quality concerns. Below are the problems I have encountered: 1.Thermostat and Coolant System Defects: Like many other owners of the 2022 Hyundai Palisade, I have experienced problems with the thermostat and coolant system. My vehicle has exhibited signs of overheating, posing risks to the engine-??s longevity and safety. 2.Radiator Leak: I have identified a radiator leak, which is troubling for a relatively new vehicle. This suggests a defect in the materials or assembly, as this should not be occurring under normal operating conditions. 3.Oil Pan and Filter Housing Issues: -??The oil pan has developed a crack, which is highly unusual, especially since Hyundai has performed all of my vehicle-??s oil changes. This raises concerns about part quality and service handling. -??Additionally, I have noticed oil leaking from the oil filter housing. This leak not only raises concerns about engine performance but also indicates a potential flaw in the design or installation of the oil filter system. 4.Faulty Sensors: My vehicle-??s sensors frequently activate without any nearby objects or obstacles. These false alerts are a serious distraction while driving and undermine the effectiveness of the car-??s safety features. 5.Key Fob Malfunctions: While driving, I have repeatedly encountered the -??key not in vehicle-?? warning, despite the key being present inside the car. This issue is not only an inconvenience but also a potential safety risk if it disrupts the vehicle-??s operations unexpectedly. The combination of these defects is unacceptable for a vehicle of this age and reputation. These problems suggest significant flaws in manufacturing, design, or maintenance practices that Hyundai should address immediately.

In April 2022, we purchased a new 2022 Hyundai Palisade from a dealership due to persistent issues with our previous Hyundai Santa Fe, which had ongoing engine problems and recalls. After multiple unsuccessful repairs and software updates on the Santa Fe, we decided to trade it in for the Palisade. Since the purchase, the Palisade has undergone over ten warranty-related repairs. In early 2023, an oil consumption test revealed significant warranty concerns, leading the dealership to keep the vehicle for additional diagnostics. This process lasted nine months and included a full engine replacement. During this time, my husband filed a complaint with Hyundai Corporate, seeking a lemon law buyback or an equivalent trade-in. Hyundai Corporate denied our request, stating that we did not qualify under the lemon law and refusing to buy back or offer a fair trade-in for the vehicle. In June 2024, after nearly a year of repairs, we retrieved the vehicle, only to experience severe issues shortly afterward. The Palisade began jerking and shaking on the highway, and the check engine light came on. The dealership identified a faulty mass air flow sensor and ordered parts for its repair. They assured us it was safe to drive until the repair was completed. However, the next day, the vehicle displayed the same issues. A diagnostic at Auto Zone revealed problems with both the air flow sensor and the fuel injector, indicating unsafe driving conditions. We returned the vehicle to Hyundai College Station, where we received a loaner car while they conducted repairs. During this period, we were informed of a "computer digital data hack" that prevented the dealership from providing documentation of the services performed. When we picked up the Palisade, we were told that only the mass air flow sensor had been repaired, with no work done on the fuel injector or other issues. Currently our vehicle exhibited engine defaults and the engine light came on. It is at Principle Hyundai for repairs

On January 21, 2024, I was driving the Palisade about 80 miles away from home when I got Engine Overheated message multiple times. The temperature gage would go up and to max then goes down multiple times. Finally it was discovered that the coolant was leaking. The vehicle had about 31,000 miles. It was supposedly inspected when after 30,000 on December 28, 2023. The car was towed to a nearby dealer. Since it was Sunday, I had to rent a car and went home. next day I called the dealer and was told the car would not be checked for another month at least. I was told to find other dealer in the area that can handle the inspection and fix if I wanted the car any sooner. I complained vehemently. I gave up and called other dealers in the area. Finally the same dealer called back and said that they have looked at the car it turned out there is technical bulletin for the issue. I was told to come down and get a loaner. I traveled to that location next day and picked up a loaner as my car is the only car we have. I talked to the dealer where the car was inspected last December and was told that service departments do not loo at TBS unless the owner raises an issue. I do not have access to TBS to check what's out there. This issue should not happen to consumers. Bulletins and recalls should be available publicly to all consumers to be aware of issues. I'm not sure where to go get TBS for my car. I found Hyundai's site for recalls. Nothing else. This should be addressed at the national level. Attached is a file that contains pictures of the coolant reservoir, at the beginning, after adding more coolant, then at end when it became clear coolant level is coming down.

The vehicle went into limp mode while traveling on the highway. Vehicle decelerated from 65mph to 30mph very quickly & without warning (no indicator lights came on). I was almost rear ended, since the car behind be had no idea I was decelerating due to no brake lights. It then slowly decelerated to 14mph as I was able to get off highway. Upon inspection, by me, the vehicle was found to have very little oil & I do get my oil changes on the required interval at the dealership. It had been about 2500miles since my last oil change. This vehicle is available for inspection if needed. No warning lights or messages came on & the app that notifies of problems stated the car had no issues. The vehicle has been to the dealership multiple times & I have been made to come back every 1K miles for oil consumption tests x 3. As of the 3rd test, it has been calculated that my car is burning 1qt or oil every 775miles. The dealership is requesting a new engine for my vehicle. Hopefully it will be approved. But, I personally feel this is a major safety hazard to just have your car stop at of nowhere with no warning light or alarm.
