2022 Hyundai Palisade Transmission Problems

Your 2022 Palisade suddenly lost all engine power while driving at normal speed, with multiple warning lights appearing on the dashboard at once. The vehicle slowed down dramatically and became unsafe to drive, forcing you to pull over. After stopping, the engine would not restart and required a tow. This sudden power loss could pose a serious safety risk, especially if it happens on a highway.

Your engine intermittently loses power without warning while driving at normal speeds or during acceleration, causing the car to hesitate and not respond to the gas pedal. This happens randomly and doesn't always trigger warning lights or error codes, making it difficult to diagnose, but the power loss is noticeable and creates a safety risk when merging or driving in traffic. The issue has happened multiple times even after service visits. The problem may be related to engine timing or the powertrain system and will likely require diagnostic testing and repair of the ignition or fuel delivery components.

Your car's radiator failed and was replaced, but afterward the radiator hoses kept coming loose and needed to be retightened. The upper radiator hose was eventually replaced, yet you continue to experience coolant leaks every winter that require service visits. You've also experienced delays with Hyundai addressing recall issues and obtaining recalled parts.

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.

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.

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.

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.

While driving northbound on Garden State Parkway vehicle lost acceleration and had to pull off the road at exit 132.

See attached document for complaint.

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.
