*Median odometer reading when the problem happened, where owners gave one. One complaint can name several problem areas.
Forward collision avoidance › Adaptive cruise control
While using the cruise control, the forward vision warning system activates even though it has been turned off. This is not unexpected as the ownerâs 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…

2026 Genesis G70 2.5T RWD. The navigation system is completely gone. There is absolutely no way to get the maps or even the navigation settings menu up. On every startup, you can see a part of the screen which shows it tries to load navigation, but fails every time. There are a few critical safety issues with this. To start, a main feature of the Adaptive Cruise Control is relying on GPS map data to anticipate sharp bends in the highway. If the navigation system cannot provide this layout data, the adaptive cruise control will not automatically slow down for upcoming curves, forcing the driver to intervene suddenly or risk carrying too much speed into a turn. Missing speed limits: If the…

This complaint is a follow-up to NHTSA Complaints #11714226 and #11730299 regarding the same unresolved safety defect. Since those complaints were filed, the vehicle has now been involved in a SECOND defect-related crash. I repeatedly begged Genesis not to return this vehicle to me because I believed it was unsafe to drive. They refused to state the vehicle was safe or unsafe. No risk to them.Genesis scheduled a fourth repair attempt, took possession of the vehicle, but did not repair or even diagnose the steering and braking defects before returning it to me. Despite my repeated warnings that someone could be seriously injured or killed, I was forced to continue driving a vehicle that was…

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 (50â79 mph) without driver input and with no obstacles present. During multiple events, the steering becomes temporarily unresponsive or âlocked,â 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…

While driving at highway speeds (55â73 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…

I am submitting this report to document a serious and dangerous safety defect involving my Genesis G70. Note - Your system pulls my VIN as a G80, I own a G70. On two separate occasions, the vehicle applied braking without driver input and abruptly veered to the left, despite there being no obstacles, vehicles, or road hazards present. During the first incident, the vehicle was operating in Comfort mode with Lane Assist enabled. During the second incident, the vehicle was operating in Sport mode with Lane Assist disabled. In both cases, the braking felt as though it was applied to the front-left wheel, causing an immediate and forceful deviation of the vehicle to the left. Both incidents…
