2023 Hyundai Kona

P235/40 R19 Pirelli P-Zero driver and passenger front tires and rear driver. Purchased Hyundai Kona N on Oct 25, 2023 new (<50miles). Vehicle sold new with these tires already installed. Pressure always maintained per recommendations. Noticed tire cracking and stability issues several months ago. Vehicle has 4000 miles on it now. Front driver and passenger tires are heavily cracked and throwing off chunks of rubber from tread. Rear driver side tire showing slight signs of cracking. Rear passenger tire seems ok. Integrity of the tires are compromised. Highly concerned about a major blowout of the tires. Vehicle is available for inspection upon request. My personal safety and the safety of my children are at risk from major tire blowout, loss of control of vehicle, major accident, injury and/or death. Emailed and spoke with representatives at Palatine Hyundai (Dealer of Sale) on May 9th requesting pro-rata replacement of the defective tires... never was contacted back by the dealer or any representative. Emailed with representatives of Pirelli Tires on May 9th requesting pro-rata replacement of defective tires... was told that there was nothing they could do because the vehicle with the tires was purchased in Illinois and terminated all communication with me. Called Hyundai Customer Assistance and opened a case with them. I was told that even though the vehicle was purchased with the tires installed by dealer, they couldn't do anything and that I should contact the tire manufacturer. I followed up with the call and added photos of the defective tires to the associated case number with Hyundai. Do my kids or I need to die in a car crash before action is taken by the dealer, tire/vehicle manufacturer, or a governmental agency? How far does this need to go?
