Assist problems of the 2025 Honda Odyssey

While driving straight on the highway on a sunny day the car left the lane on it's own, resisted attempts to get it back into the lane, and crashed into the concrete barrier after we swerved around and the car bounced around. Lane keeping assistance and automatic cruise control were active. The lane lines looked perfectly fine. A couple minutes before the accident the car left the lane unexpectedly but we were able to get back into it. Before going on the trip we took the car to the dealer and complained about issues with the car not starting after it shut off while idle at stop lights, or not starting properly, like engaging the parking brake and getting stuck, or starting and rocketing forward even when I only pressed lightly on the gas, leading to loss of traction. They checked the car and said everything looks fine and the tires have 5mm of tread and don't need to be replaced, and they rotated the tires and changed the engine oil. I'm not sure if the issue was with the power steering failing, or traction being lost, or the sensors having an issue causing the car to think the lane was somewhere else and not letting us leave where it thought the lane was. Driver has tons of bruises still and it's been over a week. The other 4 passengers seem ok. The insurance company said the car is totaled and is taking possession of the car. The only warnings lights or messages the car gave us before the accident were about the car having an issue starting back up when all the cars were beeping behind us when the light turned green, and messages about loss of traction, mainly after the engine started back up.

We get a warning light saying "adaptive cruise control system problem". Van has 4200 miles and it happens during hot days, usually at lunch time. I took it to dealer "Honda cars of rock hill, SC" but they told me there is no code showing up in the van. I emailed Honda America with video but so far no response. The system just goes crazy, beeping and the cruise control is no responsive to cancel button or anything. We are not even using the adaptive cruise control when this happens. After you drive for a while, it goes away, like nothing happened. But when another hot summer day comes, around lunch time, it goes. . . It does it pretty much during high temps. Never in the evening or night time. Here is link to youtube video I sent to Honda: [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

While driving in a construction zone, the vehicle's lane departure system jerked the wheel and almost made me leave the lane very dangerous. Same vehicle, the a'c was found not operating and a dealer diagnosis found that the system was overfilled and that an electrical connection was not hooked up from the factory. Same vehicle, body panels are not properly aligned from the sliding door to the passenger side door, gap is almost 1/2 inch.
