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 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 contact owns a 2022 Hyundai Palisade. The contact stated that when the vehicle it was purchased, the VIN was included in NHTSA Campaign Number: 22V633000 (Trailer Hitches) and was repaired. The contact stated that after the recall repair was completed, the radiator suddenly failed, and the vehicle would overheat, and the heater failed to operate as needed. The vehicle was taken to the dealer who diagnosed that the radiator had failed and needed to be replaced. The radiator was replaced. After having the repair completed, the vehicle would shake while accelerating and driving at various speeds. The contact stated that failure mostly occurred while the transmission was shifting into 2nd gear. The contact stated that engine was overheating and the coolant reservoir needed to be refilled every day. There were no warning lights illuminated. The vehicle was taken to Tasca Central Avenue Hyundai (111 S Central Ave, Hartsdale, NY 10530); and it was diagnosed and determined that the transmission was slipping and needed to be repaired. The vehicle was returned to the first dealer who diagnosed that the coolant hose had failed and needed to be replaced. The vehicle was not repaired. The contact retrieved the vehicle from the dealer, and the transmission warning light was illuminated. The manufacturer was informed of the failure and opened a case. The failure mileage was approximately 40,000.

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.

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.

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.
