This supplements my prior complaint, ODI #11751961, for the same vehicle. Following that complaint, an authorized dealer performed front camera and front radar ADAS calibration on 7/21/2026 and returned the vehicle as operating as designed; the manufacturer's representative confirmed in writing on 7/22/2026 that the camera had been within specification. On 7/23/2026, approximately 1:21–1:35 PM, driving in the left lane of a divided parkway with a concrete median barrier, with HDA2 and Lane Following Assist both active and indicating green, the steering wheel turned the vehicle toward the concrete barrier at least seven times, requiring manual correction each time. This occurred both with a lead vehicle approximately 4 seconds ahead and with no vehicle within more than 10 seconds ahead. Earlier the same day, driving the opposite direction with both systems active and green, the vehicle applied hard automatic braking twice with no vehicle within more than 10 seconds ahead (traffic present only in the adjacent lane); I had to manually accelerate because a following vehicle was close behind. My original complaint reported the automatic braking failing to activate; the system now also activates falsely. Additionally, the hands-on-wheel warning repeatedly illuminated while my hands were on the wheel, taking approximately 30 seconds to detect them. I have stopped driving the vehicle. The manufacturer was notified in writing the same day, and a second repair visit is being arranged. No crash or injury has occurred.

Back-up camera stopped working. Upon Reverse, a green screen appears that says "No Camera Signal Received. Please try again later". Green screen disappears when car is put in Drive. Issue did not correct itself upon on/off cycle. Car will be taken into dealer for repair.

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 contact owns a 2025 Genesis GV70. The contact received notification of NTHSA Campaign Number: 26V229000 (Fuel System, Gasoline); however, the part to do the recall repair was not yet available. The local dealer was contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was not made aware of the failure. The contact had not experienced a failure.

Auto Start Stop seemed to have malfunction and shut the car off completely. I had to restart the car in traffic to get going. This happened twice, once going to work and once on a weekend trip to New Jersey. The only thing that's preventing an accident is you have to stop for the auto start feature to even activate.
