Two problems with the horn since I purchased my car in Dec 2004: 1) sounds when I haven't even hit it at all and 2) won't sound when I need it unless I hit it in exactly the right place which seems to change every time I need it! a couple of times when it sounded on it's own it lasted almost a full minute! hitting it had no effect. And then, a couple of times when I needed it, it never sounded! this scares the I-don't-know-what out of me and everyone around me! I've taken it to darcars on branch avenue in marlow heights, md. A number of times in 2006. They were able to repeat symptoms, and did do something that fixed problems for awhile. But problems keep resurfacing. Second week of Jan 2006, horn went off on it's own while I was in a curve to the right, and the car to the left of me almost went off the road. Serious safety issue!! almost better to not even have this horn!

: the contact stated the horn only sounded with extreme pressure being applied to the right side of the steering wheel. The horn did not sound when any other area of the steering wheel was depressed. The vehicle was taken to the service dealer, who determined the horn was not working properly, but could not determine how to remedy the problem without possibly causing the airbag to deploy. The only work completed by the dealer was an attempt to remove the steering wheel cover to inspect the horn connection. This resulted in the horn sounding continuously. Therefore, the dealer disconnected it completely. The dealer, who was a Ford dealer, recommended taking the vehicle to a Mercury dealer for further inspection. The manufacturer has not been contacted. The horn has since been repaired. Updated 05/30/06.

Horn does not blow. Noticed almost immediately after purchasing vehicle. Dealer did not know how to fix, said all models had this problem. Consumer states that after contacting NHTSA and Ford 3 days later, consumer received a call to bring the car in for repairs and it only took a half hour to fix the defect.
