If anyone here claimed to have definitive answers to those questions, would you believe them?
Car companies are lousy at getting timely details to consumers about model-year changes. Just awful. E.g., Monroney stickers for built 2023
Palisade are already circulating, but the Hyundai website has no 2023 configurator or other detailed model information, just auto show-style generalities. Kia is no better -- maybe worse, since I don't think you can tell from the primary Kia website that the 2023 Telluride has even been announced yet (a search for "2023 Telluride" yields nada).
