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 engines 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 vehicles 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 vehicles sensors frequently activate without any nearby objects or obstacles. These false alerts are a serious distraction while driving and undermine the effectiveness of the cars 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 vehicles 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.
