I bought a used 2016 Hyundai Santa Fe Sport in mid-November 2021 with 67,000 miles. December 23, 2021 with 69,500 miles, driving from Hillsboro, OR to Northern California, my car suddenly went into safe mode. Won't go over 40mph or 2 RPMs. No idea what to do. Did an Engine Code and it's P1326 - Knock Sensor System. Royal Shield warranty is 3 month, 4,000 miles but not sure if they're going to cover. Or if Hyundai will cover it since they did the Service Campaign 953 back in 2019 which deals with the Knock Sensor stuff. Very annoyed.
