2026 Genesis G80 Reliability Report

The car was purchased on [XXX]. On [XXX]—only six days after purchasing the car—it failed to accelerate through an intersection while turning left in front of oncoming cars. Less than a week later, on [XXX], the car again failed to accelerate as it slowed down entering a rotary on [XXX] . The same thing happened again on [XXX] as it was driven out of the Savannah Bend Marina, turning left onto [XXX] , and yet again on [XXX] while driving around a traffic circle on [XXX] . On [XXX], the car once again failed to accelerate when attempting to clear an intersection on [XXX] Pooler, a Savannah suburb. On [XXX], after starting the car in the garage, it obviously had a problem running while idling. Backing out of the carport and pulling out onto the street, it barely responded. Even after the accelerator was practically floored, the car would go only about 35 miles per hour. On [XXX], the car yet again delayed in accelerating while turning left onto [XXX] from [XXX] . As it turned left and the accelerator was pressed down, the car slowly inched forward for a few seconds before finally accelerating and clearing the intersection, barely averting a collision with oncoming traffic. The dealership has had multiple attempts to repair the defect, but it has been unable to locate or remedy the defect. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving at highway speeds (55–73 mph), the vehicle has repeatedly and unexpectedly applied the brakes on its own and on at least one occasion experienced a loss of power. These events occurred without any vehicles, pedestrians, or obstacles present, and without any driver input. Road and weather conditions did not warrant braking. On multiple occasions, the vehicle suddenly decelerated while adaptive cruise control was engaged, then immediately re-accelerated back to the set speed. This created a serious risk of being rear-ended or involved in a high-speed collision. On one occasion, the vehicle experienced a loss of power while driving at highway speed, requiring immediate driver intervention to avoid a dangerous situation. These incidents make the vehicle feel unpredictable and unsafe to operate as intended. I regularly transport family members, and these failures place my safety and the safety of others at significant risk of serious injury or death. The vehicle has been inspected by an authorized Genesis dealership on two separate occasions. Despite extended road testing, the dealership has stated they were unable to reproduce the issue and no permanent repair has been performed. The manufacturer has been notified, and the defect remains unresolved. No warning lights or messages were present prior to the incidents. The failures occur suddenly and without advance indication.
