Driving interstate right lane cruise control set at 73 mph. Car in front of me proceeded to leave lane to the left in order to pass 18 wheeler in front of it. Noticed my car felt different at that time and looked at dashboard to see cruise control now set to 110 mph and speed almost 90 mph. Documented with photo. Disabled cruise with breaking. Shared this on Tucson forums reddit and Hyundai forums with confirmation that this has and is happening.
Driving on highway long distance on sunny days the radar becomes blocked disabling critical forward safety functions and cruise control. Numerous times this has caused a near collision due to the automobile malfunctioning. Many times my cruise control has just stopped working and my vehicle has rapidly decreasing speed, causing people behind me to have to slam on their brakes. My vehicle has also automatically braked on the highway when there was no one in front of me. These are just two incidences that have nearly resulted in collisions on the highway. This has been occurring since I purchased the vehicle in September 2022. Unfortunately, dealership has not been able to duplicate what has occurred.
