What 35 owners told NHTSA about the 2023 Genesis Gv80 Coupe

The Adaptive Cruise Control will slow the car down or try to bring it to a stop from speed on a highway for no reason, with no other vehicle in close proximity. Sometimes it occurs on a curve when the car seems to react to a guard rail or snow bank. Very often it is on a long straight stretch of road with no one in sight. Car just aggressively decelerates. The only action is to press the accelerator or shut the cruise control off in order to overcome the problem. Clearly this puts vehicle occupants at risk because the car creates a risky driving situation on highways. Have brought it to a dealer where the service manager acknowledged that this is an issue with this vehicle that others have complained about, but Genesis has not addressed. Message boards and Genesis on-line forums are filled with similar complaints. There were no warning lamps or other indicators for the problem.

Forward collision warning and active assist are practically inoperable. The vehicle doesn't detect the car in front of it and doesn't show it on display. The operation doesn't match the described function in the owner's manual. After trying to work with Genesis Corporate office and dealer, I could replicate the problem during the test drive that was conducted after dealer performed extensive diagnostics together with Genesis tech support. System didn't return any fault codes. Dealer documented the issue in the service record. During the test drive, the WARNING system finally activated when collision would have been imminent only prevented from the accident by the technician driving by slamming on the brakes. The emergency braking system didn't activate at all. I drove various loaner cars being Genesis 2023 models that all exhibited the same behavior. According to the manual the system should be active at the speeds 6 miles per hour or above. I can get very close to the car in front of me and nothing would happen. It only affects normal driving. Adaptive cruise control works fine and sees the vehicle in front of me with no issues
