INCIDENT ONE: On 3/20/25 about 5 minutes after starting Climate Control on my Ioniq 6, I cleaned snow off the car and started it. As I started backing out, there was a loud warning sound and red indicators around the aerial image of the car on the dashboard. I double checked my surroundings and found no obstructions, so I continued to back out. As I began to turn the car into the direction I needed to head down the street, the car abruptly stopped. I had to put the car back into Drive and pulled forward. I checked again for snow on the bumpers and found none, so I backed out again, this time successfully. When I reached the intersection and tried to turn, the car again abruptly stopped and automatically sounded the horn. The car stopped in the lane of oncoming traffic, but there were no cars approaching. Again I had to put the car back into Drive. I pulled over and took a cloth and glass cleaner to wipe down the cameras. After doing this, I was able to continue on my commute without seeing red lines around the image of the car and without being abruptly stopped when turning. The dealer was unable to reproduce the problem, which they attempted to do under different weather conditions from those on the morning of March 20th. INCIDENT TWO: On 4/7/25, driving on a four-lane highway, a car pulled in front of me without signaling. I tried to alert them to my presence by sounding the horn. The space in the center of the steering wheel (with the horn icon on it) produced no sound when pressed. This was alarming. Fortunately I was able to slow down, and I was not hit by a car from behind. Later. I tried the horn again several times with no sound produced. The dealer repaired the horns.
