I purchased this vehicle on [XXX] in the state of Colorado and had to drive it home through a winter storm to California. While driving home the vehicle on multiple occasion the vehicle flagged driver assist disabled or inoperable errors due to ‘radar blocked’ stopping and checking the front of the vehicle I found that the car had no snow or ice build up on the exterior of the bumper, and there was no reason that all the driver assist and even safety features like Automatic Emergency Braking had been disabled. In addition while making this drive home, the vehicle passenger side wiper failed catastrophically. Over a 30 day process the local dealer replaced the broken wiper blade motor, and determined there was nothing wrong with the internal Auto assist system, even stating there were no DTC/ or error codes present. I provided them with images of the errors and millage, but nothing further could be done because they could not ‘replicate the issue’ and no codes are being stored. At around 1430 miles I was driving in dry, warmer weather (around 50 degrees) when another error flashed on my screen again. I brought the vehicle back to the dealership for diagnostics, where they have yet to determine the issue again. They’ve stated no DTC or error codes are present, and they can not reproduce the issue so the vehicle is operating ‘normally and designed’. I have been working with Hyundai Consumer Affairs during this entire time to help speed this process along, they have no answer other than, if the error appears again, do not turn of the vehicle, drop everything your doing in your life and bring it directly to the dealership for diagnostics (even if its active safety features are not working while your driving it).
