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 federal safety agency 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.

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.

I had a "engine overheat" warning while I was parked. I checked and noticed the coolant level was low. So, I added coolant and the warning went away. I thought it was just a one-time thing. After a week, I parked my car while I went to pick up something at the store. My mother was in the car so I left the car running. When I came back, I noticed a very strong smell of coolant and saw the "engine overheat" warning again, the car was blowing hot air. I turned off the car and opened up the hood and saw coolant liquid was all over and also on the floor. I called Hyundai roadside assistance and they picked up the car after 5 hours of waiting. The next day, I called them and was told the radiator was cracked. It's been three days. I'm still waiting for their call.
