NHTSA Complaint #11541716 — 2016 HYUNDAI SANTA FE

On August 11, the car suddenly lost power/acceleration & the dashboard lit up with engine, battery, and oil lights. I coasted down the hill to our home without any power. On Monday, it started again without lights, but we called the dealer & were told it would be 4.5 weeks before they could see us & there was nothing they could do without lights on the dash. So we took it to a nearby service center. They performed an oil change & compression check & deemed everything fine. The car drove mostly fine, with an intermittent pause/hiccup at stoplights. August 26, at highway speed, the car shuddered loudly, & the engine light flashed. As I coasted to the shoulder, there was a POP sound. I parked, turned off the car, & inspected the tires. The rear passenger tire had a 3-in gash but didn't deflate. I tried turning on the car again & it just ground & jerked with the flashing engine light. I called AAA & towed it to the dealership, where it's waiting to be inspected. This is a Theta II engine & received the KSDS software recall update in 2019. My child was in the car with me. I wonder if the KSDS gave the first warning on Aug. 11 but failed to stay on to pass on the data to the service center.
