2026 Genesis GV80Recalls, problems, MPG & safety

“The Advanced Driver Assistance System (ADAS), specifically the Intelligent Speed Limit Assist (ISLA), suffered an unprompted phantom activation and electronic control module lockup. The vehicle is currently located at the Genesis dealership service center and is available for inspection. On [XXX], at [XXX] AM, I was driving 60 mph in the far-left lane of [XXX] approaching the [XXX] (near the River Road ramp). Without any driver input, the vehicle executed an unwanted command, forcibly dropping my speed from 60 to 30 mph in less than 3 seconds. My safety was put at extreme risk as an 18-wheel semi-truck directly behind me almost rear-ended my vehicle. With no left shoulder available, I had to turn on my hazard lights and cross 5 lanes of high-speed traffic at only 30 mph to reach the right shoulder, nearly causing multiple accidents. The vehicle completely locked out the throttle until I performed a hard reset by cycling the ignition off and on. There were no symptoms prior to the failure, but during the event, the infotainment screen repeatedly flashed the word "LIMIT." The vehicle has been inspected by the manufacturer's dealership since Sept 10th. Technicians…”

“Traveling along a 2 lane highway, I came to a complete stop while waiting for a safe opportunity to turn left onto a side street. When an opportunity to turn became available, I pressed the accelerator pedal and began making the left turn. Almost immediately, the vehicle lost its ability to accelerate and stopped moving forward as expected. Despite pressing the accelerator pedal firmly and repeatedly, the vehicle would not respond normally and would not continue moving forward. I was actively pressing the accelerator, but the vehicle behaved as though I was not pressing the pedal at all. At that moment, oncoming traffic was approaching, creating an extremely dangerous situation. Because the vehicle would not accelerate as expected, I was unable to proceed through the turn normally, placing me at serious risk of being struck by approaching traffic. The engine did not completely shut off. Instead, the vehicle appeared to sputter and struggle for approximately 5-10 seconds while I continued attempting to accelerate. After this period, the vehicle unexpectedly regained power and resumed moving forward normally. No collision occurred. However, the incident created a…”

“This car has stalled 3 times. Randomly, but each time while car was fully stopped. Once when I was sitting in a parking lot about to pull into traffic, and when waiting for a light to go from red to green. After these two times I took car to dealer. They ran diagnostics and said there were NO error codes. They tried to reproduce but could not. I asked them to reset all computers in car, which they did. But it happened again yesterday. This third time, weather is nice, about 68 degrees. I had been driving about 3 miles, waiting for a light to change. I believe the car went into “Auto stop”, like usual, but when light changed and I took foot off brake, car stalled. It then BEEPS rapidly at me, and I believe the warning message says something like “Can not start car in Drive, please put in Park”. As cars are behind me and honking furiously, I put drive selector into P, and push start button, it starts and I drive away. Safety issue is cars behind me, expecting me to move, and I can’t. I worry about being rear ended. Each time I believe car had gone into “Auto stop” mode to conserve gas. Each time Weather was clear and normal. One time it happened with my wife in…”
