NHTSA Complaint #11527785 — 2021 HYUNDAI KONA

the bcw tends to go on every time the vehicle is driven on a rural two way road to town, approx. less than 20 miles. been to dealership for the problem with the bcw ,paid for diagnostic and scanned for codes ,none apparent.the dealership did minimal calibration without realalinig the sensor. the vehicle will automatically downshift causing the vehicle lurch which is totally unsafe.this began at 6000 miles.no obstructions to sensors as per dealer inspection.a brand new suv awd never been offroad ,or any collision whatsoever.reading forums leads me to believe it occures quite often to this particular vehicle.i called the local global representative and have a case number of 21601680, i thank you for your prompt response to this issue.
