Assist problems of the 2026 Hyundai Palisade

I am reporting multiple recurring safety concerns with my 2026 Hyundai Palisade. Loss of acceleration: under heavy throttle, the engine revs to approximately 5,000 rpm but the vehicle does not accelerate as expected. This has occurred repeatedly and appears more likely after the vehicle reaches normal operating temperature. During one incident on the highway, I needed to accelerate quickly to avoid surrounding traffic, but the vehicle did not respond as expected, creating a potential safety risk. An authorized Hyundai dealership inspected the vehicle and reset the transmission adaptive values, but the condition remains. Lane keeping assistance: the lane keeping assistance system consistently positions the vehicle toward the left side of the lane instead of properly centering it. The issue has been reported to the dealer, but the condition remains unresolved. Power second-row seat: the power second-row captain’s chair can continue moving while folding, creating a hand-crush hazard if a person’s hand is in the path of the seat. It also interferes with proper third-row seat operation. This issue has been reported to the dealer and remains unresolved. These issues have been reported to Hyundai and remain unresolved after dealer inspections. The vehicle is available for inspection, and I have documentation and video evidence of the acceleration concern.

When using "lane keeping assistance" the vehicle pulls slightly to the right and continues correcting itself creating a snake like pattern. This is unsettling and other vehicles that I own do not have this pattern including the same model from previous years. This feature is design for safety, however when "lane keeping assistance" in operation the pulling to the right looks like you are going into the other lane then correct's itself and repeats not giving the feel of safety. I have taken it do the dealer and file a report to Hyundai both parties had stated they cannot do anything without an error code. I have seen other customers complain about this issue with my make/model. Please help correct this issue. Thank you.
