NHTSA Complaint #11719072 — 2024 HYUNDAI SANTA FE

One of the original OEM tires (Pirelli Scorpion MS KS NCS XL - 245/45R21) had the acoustic dampening foam on the inside of the tire fall apart. Dealership indicated that there was 'no impact damage or modifications found with the tire during inspection; meaning this was likely a manufacturing defect due to adhesion issue. Despite the problem and the fact that this tire has less than 12K miles on it at the time of the incident, the local Hyundai dealership, Hyundai corporate and Pirelli all refused to cover the cost to replace the tire. Hyundai dealer said to file a complaint with Hyundai corporate, Hyundai Corporate said that this was a Pirelli tire warranty issue (no paperwork provided about Pirelli tire warranty at time of purchase) and Pirelli indicated that only the local dealer or an authorized dealer of their tires can submit warranty claims, and that it is contingent upon a Pirelli inspection and prorated based on the remaining tread of the tire. This leaves the consumer in a difficult position having to bear the burden of the tire replacement cost upfront, and little chances of recourse as these 3 parties skirt responsibility of the OEM tire. When the acoustic foam fails, the car shakes violently at high speeds, for us this stats at ~50mph. There is no warning light that appears for this, dealer originally thought this was related to ice build up which did not rectify the problem causing us to have to go to the dealer twice for diagnostics. Online forums seem to point that this acoustic foam adhesion issue is especially common in colder climates. Symptoms of problem first appeared in early January, with full diagnosis confirmed early Feb.
