GENESIS G80 2025 VEHICLE SPEED CONTROL
lowOn Oct 14, 2025 I was traveling on route 287 north in cruise control set at 67 mph. Suddenly the dashboard screen went black and the car floored itself. The gas pedal went to the floor. It took a few seconds to realize what was going on. When the dashboard lit back up I was going over 100 mph. I quickly applied the brakes which disengaged it. It never happened again. The car is currently at the dealership but they could not reproduce the problem. They said it did not throw a code either. I felt it was important to report this so I am.
GENESIS G80 2025 LANE DEPARTURE: WARNING
lowDriver attention warning "consider taking a break" too sensitive, too frequent and too random, happens every 7-15 minutes with loud beeps. Very annoying and distracting, and the feature cannot be turned off.
