NHTSA Complaint #11518919 — 2023 HYUNDAI SANTA FE

2023 Hyundia Santa Fe bought brand new from the dealership. During the course of the last month and a half the vehicle has done things with unknown origin. The panic alarm will randomly go off when the vehicle is turned off, no one is in it, or even near it. By locking the vehicle with the remote, the alarm will tend to go off about 20-30 seconds after the vehicle is locked and will sometimes not stop until the vehicle is restarted. The transmission will shift very roughly almost to the point that it feels like you are driving a manual transmission vehicle. The transmission lags in gears between 60-70 miles per hour and you feel a very rough back and forth shifting with in the transmission. Next the emergency break would engaging and then not releasing or reengaging when parked on a hill, flat service or anywhere. The break light on the dash would light up, blink, then it would go off, making it unknown if the emergency break was acting engaged or not. The dealership I purchased it from did replace the EMS module along with breaks and rotors on the vehicle. The auto shut off or the idle shut off will also randomly work, and not work. it will cut on and off even if the button is pressed to shut it off or prevent it from coming on. Now the air condition, along with the heat and heated seats has started to not work, randomly cut on, will not cut off etc. While driving i have had the heated seats turn on, along with the heat and not go off, nothing would cut off until the vehicle was physically turned off and restarted. No codes have ever been displayed or found by the dealership.
