After the recall to prevent a short between horn and air bag was completed in 2011 a short time thereafter in the middle of the night the horn came on by itself in the locked vehicle with no one in it. After trying everything I could think of like starting the engine and pushing the horn button numerous times. I was about ready to disconnect the battery when in anger I hit the center of the steering wheel very hard with my hand and the horn stopped blowing. From that day on the airbag warning light stays on when the engine runs. And the horn blows half as loud as it originally did when activated. Ford says its my problem because the recall was already completed. Only problem here is that that their was no problem at all until after the recall work.
: the contact stated while stopped the vehicle lurched forward without warning. The engine revved to 5000 rpm and the tires spun and were burning rubber. The dealer could not duplicate the problem and no repairs were made. The horn assembly was replaced. Updated 03/17/06.
