“The Acura key has a hinge on it with a release button and a spring where the keys open when the button is pressed and the key locks in place. The locking mechanism on the hinge failed.

My car has turned off without warning due to the key hinge lock failure on the highway ant speed and well as on bumpy roads and at stoplights.”
