On December 28, 2024 my family and I were in a crash with our Pacifica van. In a gradual left turn at approximately 40 mph, the van slowly drifted to the right. I slowly corrected to the left with no affect. After slightly more left correct, the van cut hard left and crashed head into a concrete wall on the opposite side of the roadway. The steering correction inputs should not have resulted in such a hard left turn. The drift to the right should not have occurred and I was not able to correct for some reason. The vehicle was inspected by insurance and totaled. No other inspections were completed to my knowledge. There were no issues or warnings of a potential problem. We did suspect the lane keep assist system could have caused an over correction but have no way to confirm that.
