2026 Genesis G-Class problems

“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.”

“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 unsafe. On June 24, 2026, while traveling approximately 20 mph, the vehicle suddenly veered right. The steering became unresponsive, and the brakes behaved abnormally, causing me to leave the roadway and fly into a ditch. I struck my head, and this crash closely mirrored the first defect-related crash on March 29, 2026. This occurred after four repair opportunities and after Genesis had actual knowledge of the repeated steering and braking failures. The defects remained…”

“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 navigation system fails, the car may display the wrong speed limit, or none at all, increasing the risk of accidental speeding or sudden braking when a camera finally catches a sign. Reliance on phones: If the primary infotainment screen is dead or the GPS is frozen, drivers frequently resort to handling a smartphone to find their way. Looking down at a phone screen significantly increases glances away from the road, which is a leading cause of distracted-driving accidents.…”

“Genesis sent out a map update. When it was updated, it stayed in the buffering. Mode, I cannot use my display. Phone does not work map, does not work. Navigation does not work. The dashboard speed limit does not work. Everything is in the buffering mode. Spoke to Genesis corporation complaint manager several times it's been over three weeks And they have no resolution to this problem. Never even sent out any type of email notice not to update the map because of the problem. They claim it's in all the models of the year, 2026. I feel the car is not safe. Speed limit on dashboard, not working safety issue, along with display, not working buffering. Cannot get to map navigation or phone”

“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. The manufacturer was unable to duplicate or repair the defect and returned the vehicle unrepaired. On March 12, 2026, Genesis Corporate (Case Manager Terrence) stated they were coordinating with Genesis of Selma to schedule a fourth repair attempt. However, on March 26, 2026, Mike at Selma Genesis stated via text: “We as a dealer…”
