Perhaps the HAH has the 'black box' recorder, then there will be no question if the car had a problem or if the problem was between the steering wheel and the seat.

The only thing I dont care for about my HAH is that it is TOO powerful. I could be just as happy with an engine half its size. Maybe your accord simply over powered you and you have no clue what happened.

As for you buying the car, the dealer can not make you do anything you do not agree to do. You allowed him to sell you the car.

Bottom line is 'education costs money' hopefully you learned something.
