What 2026 Genesis G80 owners say
Brakes
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. …
This is a follow-up to complaint #11714226 regarding an ongoing safety defect. The defect has now resulted in a crash. The vehicle experiences repeated unintended braking at highway speeds (50-79 mph) without driver input and with no obstacles present. During multiple events, the steering becomes temporarily unresponsive or "locked," preventing driver control. The vehicle has also exhibited unintended lane departures, erratic lane changes, and unexpected acceleration following braking. Warning indicators including Forward Collision-Avoidance Assist, Automatic Emergency Braking, Driver Attention Warning, Lane Assist, and Master Warning have illuminated without cause. This vehicle has been presented three times for repair attempts specifically for these braking and steering systems and has been out of service over 30 cumulative days. …

While using the cruise control, the forward vision warning system activates even though it has been turned off. This is not unexpected as the owner's manual notes that is the case. What is unexpected is that it is virtually impossible to find a comfortable position of my head and/or the steering wheel in which the warning system does not repeatedly activate. If it activates often and/or long enough, the cruise control turns off. This is so distracting that on an eight hour trip I finally gave up on using the cruise control when it would otherwise be most useful. I wear eyeglasses,which apparently confuses the software. The Genesis representative insists this is a safety feature. In my view, it is a hazard and needs to be addressed.
