Begin by noting the problem, including the frequency of occurrence, particular symptoms (for example, not cooling adequately, weird noises, or leaks), and any attempts to resolve it. Maintain all service records, including invoices and technician notes.
Contact your local Hyundai service center and request a complete diagnostic examination of the air conditioning system.
When scheduling the appointment, clearly state that this is a recurring issue and offer copies of any past repair records. Request that a senior technician or HVAC system specialist inspect your car.
If your Palisade is still under warranty, make sure the service center is aware and processes the repair as a warranty claim.
If the service center is not responsive, or if the problem persists after repairs, contact Hyundai's regional or national customer support.
Hyundai's global support number is 1-800-633-5151, and its website is www.hyundai.com.
If the problem remains unresolved, consider filing a complaint on Xolvie to raise awareness about the issue and inform others.
