While driving at normal speed, my 2022 Hyundai Palisade suddenly lost power without warning. Multiple warning icons appeared on the dashboard at the same time. The vehicle immediately slowed down and became unsafe to operate. After pulling over, the vehicle would not restart and had to be towed. This created a dangerous situation on the roadway. I am reporting this because I wonder if other owners may have experienced similar sudden power-loss events with this model year. It was fortunate that I was on a secondary road and not on the highway when this happened because it could have resulted in fatalities.
The radiator is leaking, and from researching online seems to be a major issue with this year of car.
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.
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.
This same incident has happened twice, June of 2025 and more recently March of 2026. My vehicle will essentially have no oil left causing my car to shake while breaking and eventually the car stalls out. The first time this occurred, my vehicle stalled out in the highway and again at a 4 way stop sign. I took it to the Hyundai dealership where an oil change, oil plug and oil filter was replaced. In December of 2025, I noticed oil leaking from my vehicle, where the oil house filter was deemed the issue and was replaced. March of 2026, my car started to shake and eventually stall out again and this prompted me to check my oil levels where there was little to no oil. An oil consumption test was performed and it was noted my car is consuming 0. 5 quarts of oil per 1,000 miles. Per Hyundai, this does not meet the oil consumption warranty (1 quart per 1,000 miles) and there is nothing to do for this issue at this time. My concerns are that this issue arises prior to my next recommended oil change. Also, there are no warning signs that prompt me that my oil is actually low; no dashboard warnings or notifications. I really only know this problem is occurring when my vehicle physically shows signs while I am driving. I am frustrated with this as I have to refill oil in between oil changes but also pay for the oil changes. Also, it worries me for the safety of my family while we are driving this vehicle.
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.
While driving northbound on garden state parkway vehicle lost acceleration and had to pull off the road at exit 132.
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 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.
The contact owns a 2022 Hyundai Palisade. The contact stated while driving 30 mph, the rpm' increased quickly; however, the vehicle lost motive power. The contact was able to pull to the shoulder of the roadway, where the failure persisted. The vehicle returned to normal functionality, but the failure became a regular occurrence. No warning lights were illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the transmission. The contact was informed that the transmission needed to be replaced. The vehicle was repaired, but the failure reoccurred. The vehicle was towed back to the dealer, who again diagnosed a failure with the transmission, informing the contact that the transmission needed to be replaced again. The vehicle was repaired. The manufacturer was notified of the failure, and a case was opened. The failure mileage was 27,000.
The car had no warnings, inspection not due anytime soon but suddenly it started having blockage while driving(when it switches from one gear to next). It basically became non-drivable at any speed. Upon calling Hyundai service center, initially they were giving appointment 1 month away. Finally, they gave an appointment earlier, took the car and they suspect it’s a transmission problem and they have cars with same problems coming in and that there is difficulty in getting this part due to shortage and lot of similar complaints. This looks like a problem with the newest model as well with 10k miles on it and it can take even 3 months for us to get back our car. The point being it’s a new car, parts not available from manufacturer, and service center unable to provide an eta on when it will be fixed. Any help is greatly appreciated.
I was driving down a road with 50mph speed limit when a few of my dash lights began to come on and then go off. Then about 2minutes later, all the dash lights came on, my display screen went black, my power steering wheel froze up. I safely pulled over to a parking lot. Turned the car off. And it wouldn't start back up. I took it to the jim click Hyundai in tucson to get it diagnosed. The alternator was diagnosed as faulty, therefore killing my battery. This is an extremely unsafe circumstance for my 2 year old car to be going through. I cannot believe that this happend. I had to pay for a new battery at the dealership. Now not even 2 months later. . . My car wouldn't start. I waited 10minutes, it turned on, but it looked like it did a factory reset. I will be contacting the dealership. . . Again. But this must be looked into further. I can't believe a 2 year old car would be having these types of problems.
See attached document for complaint.
Radiator failed, replaced. Subsequent visits showed hoses loose, retightened. Continued visits had upper radiator hose replaced. Leaks every winter requiring service visits. Hyundai has been slow with these fixes. Also recalls issues have been slow and parts generally not available long after recall issued.
