2021 Kia Telluride Recalls, Issues & Maintenance

The 2021 Kia Telluride carries 5 open NHTSA recalls — most recently covering air bag/restraint control module and trailer hitches. Owners report 4 recurring issue clusters, led by “Panoramic sunroof deflector and track failure.” Kia uses Hyundai Motor Group's powertrains, so service intervals mirror Hyundai's. Kia Promise covers the first 3 years / 36,000 miles of complimentary maintenance. Kia owners with the Theta II 2.0L/2.4L (Optima, Sorento, Sportage 2011-2019) should adhere strictly to oil intervals due to known oil-consumption issues in Kia TSBs.
