NHTSA Complaint #11463972 — 2021 HYUNDAI SANTA FE

My Santa Fe has less than 14k miles. In many instances, the car has stalled when turning on. The engine would tremble and then shut the engine off while the dash lighting/symbols stay on. It will idle for a quick second and then drop to zero. Another instance is when driving into a parking spot and driveway and we applied the brakes. At that moment the engine shut off while the dash lights/radio and everything else stayed on. In all instances, if we apply the brake and then hit the start button, the car will typically turn on and act like nothing ever happened. In 2 instances, the blind side detection would turn off while driving and all the warning lights would come on the dash. After turning it off and letting it sit for a few minutes it would disappear. One time the front detection would go off and there was no car in front of me for about 8ft. The beeping continued after we drove off and it eventually reset itself and never happened again. I’ve notified the Hyundai dealer but they claim if they can’t recreate it then they can’t fix anything. My previous Santa Fe did the same thing and they had it for 2 weeks with no results. Although my blue link app showed the car was never moved from the parking spot which made me wonder if they even tried anything. I have videos of the Santa Fe stalling.
