When Highway Driving Assist / Lane Following Assist is active — confirmed by illuminated green HDA and lane assist indicators — the vehicle applies uncommanded steering torque, to the left or to the right, strong enough to force the vehicle out of its lane. This occurred on every drive, daily, from delivery on 7/2/2026 (approximately 23,200 miles) until the vehicle was brought in for service on 7/13/2026. The behavior was identical regardless of lane markings (solid, dotted, or absent) and road geometry (straight or curved), at highway speed and on local roads at approximately 30 mph. On multiple occasions the vehicle was pushed toward highway barriers (concrete median and metal guardrail, on both left and right sides) and into the oncoming traffic lane; avoiding barrier contact or returning from the oncoming lane required forceful manual correction, during which the rear of the vehicle oscillated side to side before directional control was fully regained. This occurred regardless of speed. Separately, the forward collision-avoidance / automatic emergency braking system failed to activate on multiple occasions when approaching stopped or slowing traffic, requiring hard manual braking by the driver. No warning lights displayed. An authorized dealer inspected the vehicle 7/13–7/21/2026: scans found no stored diagnostic trouble codes, road tests did not reproduce the behavior, and the dealer performed front camera and front radar ADAS calibration on 7/21/2026. I am currently monitoring the vehicle to determine whether the calibration corrected the behavior. A comparable loaner vehicle of the same brand exhibited correct HDA/LFA operation, which is how I confirmed my vehicle's behavior is abnormal. No crash or injury has occurred.

The vehicle has experienced recurring malfunctions involving the electrical system, driver-assistance/safety systems, transmission, braking system, door access sensors, and starting system. Specific issues include sudden braking events, erratic lane assist steering intervention, transmission slipping and gear slamming, intermittent loss of exterior door sensor function, failure of rear hatch access, repeated no-start conditions, dashboard warning messages, and random activation or malfunction of safety sensors. The vehicle and all affected components remain available for inspection upon request. These failures created significant safety risks to myself and others due to unpredictable braking, steering interference, drivability concerns, and the possibility of becoming stranded during interstate travel and adverse weather conditions. Some issues have been reproduced intermittently and documented through dealership service visits, vehicle logs, photographs, videos, and communications with Genesis Consumer Affairs; however, the dealership has indicated that certain conditions were difficult to duplicate consistently, particularly because many failures occur during wet, cold, snowy, or icy weather conditions not present during inspection periods. The vehicle has been inspected by Genesis dealerships, Genesis Consumer Affairs representatives, towing personnel, and is currently involved in a BBB AUTO LINE case. Prior to several failures, warning symptoms included dashboard alerts, abnormal braking sensations, transmission hesitation, intermittent warning lights, service notifications, sensor malfunctions, and inconsistent electrical behavior, which first began appearing at approximately 26,000–30,000 miles and progressively worsened over time.

1. What component or system failed or malfunctioned, and is it available for inspection upon request? Driver assist systems, including lane keeping assist, forward collision avoidance/braking system, and related exterior sensor systems, are malfunctioning. The lane assist system has taken unintended control of steering, and the braking system has activated without cause. Yes, the vehicle is available for inspection upon request. 2. How was your safety or the safety of others put at risk? The vehicle has exhibited unintended braking and steering intervention during normal driving conditions. Most recently, the lane assist system abruptly jerked the steering wheel while passing a side road opening, forcing the vehicle into a curb and causing damage. These unpredictable actions create a high risk of collision, loss of vehicle control, or being struck by other vehicles, especially in active traffic conditions. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? The vehicle was brought to the dealership for inspection; however, the issues were not reproduced during testing. Testing occurred under dry weather conditions, while the malfunctions primarily occur in wet, cold, snowy, or icy conditions. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The vehicle has been inspected by an authorized Genesis dealership service department. Genesis Consumer Affairs has been notified and is aware of the reported issues. No other third-party inspections have been performed at this time. 5. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? There have been intermittent warning messages & dashboard indicator lights related to driver assist and system functionality. These warnings have appeared inconsistently and not always at the time of the malfunction. The problems began after 30K mi and returning to NY.

We (wife and I) are the owner of a 2022 Genesis GV70. The vehicle has had multiple dangerous incidents affecting steering and driver control. Most recent event (dated 9/11/25): While driving at ~30 mph on city streets, an alarm sounded, the steering suddenly became very stiff, and the word “Emergency” appeared on the dashboard. This condition lasted briefly but made steering extremely difficult. Prior events (approx. six over the past two years): While driving at highway speeds, the vehicle has suddenly begun to swerve side to side with an alarm sounding — even though the lane assist feature was turned off. These incidents occur randomly, without warning, and cannot be reproduced on demand. Each time, she had to fight the steering to maintain control. Dealer inspection: The vehicle was taken to the Genesis dealership after earlier incidents. They found no diagnostic codes and offered no explanation or repair. Safety Concern: This vehicle appears to have a serious safety defect affecting steering control and stability. The unpredictable loss of normal steering or sudden emergency intervention poses a high risk of an accident. I request that the federal safety agency investigate this issue to determine whether it is part of a wider defect requiring recall or corrective action.

Lane keeping assist veers out of highway lane when an unlined entrance- exit appears. Vehicle is looking for the right line and swerves out of the lane to find it. Could cause a collision with an incoming vehicle. 2nd part the vehicle shimmies down the highway for the same reason when space between dashed lines appear. Constantly correcting itself. Solution would be a recall to reprogram all Hyundai and Genesis vehicles with lane following to only look at the left lines.

The issue reported has been since day one having the vehicle. The hood shakes excessively, sometimes violently, while driving at highway speeds as well as at non-highway speeds if any significant headwind is present. This flapping creates uneven and unpredictable drag that affects the straight-line tracking of the vehicle under normal driving situations. These characteristics are exacerbated by turns at highway speeds and on surface streets on particularly windy days. As the hood rises, air enters the engine compartment and causes uneven pressure changes and an unpredictable swirling and turbulent flow of air that the vehicle is not designed to handle. These combined forces acting on the vehicle throw the lane assist, cruise control, and lane departure warning systems into fits. On more than one occasion I have had to 'fight' the vehicles inputs to stay on the desired track and to avoid departing the road. Aside from immediate safety concerns, the abnormal stresses imposed on the vehicle, components, and tires are causing wear at an unknown rate and a premature component failure is likely. Napleton Genesis attempted to adjust the hood on two occasions prior to claiming to put a new hood on the vehicle. After yielding no positive results, a remedy was sought by contacting Genesis Motor America. They claimed to not know of similar complaints. After several email and phone conversations the vehicle was sent to Pugi Genesis for another failed adjustment attempt. My suspicions that it is a design flaw relating to the 'Clamshell' design of the hood were confirmed by the contact below, who stated on a recorded line on Wednesday, March 22, 2023, that she received an email from 'the engineers' claiming that they are aware of the issue and that they will not follow up because 'it is fine'. She also admitted that she is aware of several GV70 owners that have made similar claims. BRIANNA National Consumer Affairs Genesis Motor America O: 1.833.462.8723 Ext. 65009

The location of the sensors for the forward collision, adaptive cruise control and lane departure are located too low in the front grill. During snow conditions ice and snow cover the sensors and they do not operated properly. I purchased my vehicle in August 2021 and last winter as well as today (December 16, 2022 while driving near Chicago I encountered several instances where the above systems did not work properly. I contacted my local dealer as well as the Genesis Motor Vehicle company. The dealer confirmed they had several similar complaints to mine. I was advised by both the local dealer as well as Genesis Motor company to turn the systems off in snowy conditions. Disconnecting the system results in an unsafe situation. The location of the sensors is too close to the pavement. Genesis needs to correct this design flaw.
