    Why does the horn on my 2010 Dodge Nitro sound randomly? The horn sounds when the car is locked at various times.

    A lot of cars have a function whereby the horn will sound when the car is locked if there's a door, bonnet or boot ajar. It's designed to warn the driver that the car may not be fully secure even though it's technically locked.

    Sometimes, the little switches that detect whether a door is ajar can become sticky with grit and grime and don't function properly. Locate each switch and give it a quick spray with electrical contact-cleaner and you might find the problem goes away.
