Low note electric horn intermitten failure: the low note electric horn becomes inoperative below 25 degrees fahrenheit while pressing the steering wheel horn pad/switch. The high note horns operates during this. I have had several close call encounters driving on the road where I needed the horn during these periods of low temperature and the horn didn't provide adequate audible warning. I have brought this up to my local dealership and they were "unable to duplicate customer concern". This is a $50 part that should of been replaced under good will if problem could not have been duplicated even when I provided video evidence of the horn inoperative. I do not feel safe driving a vehicle that is under warranty and still making payments on with an inoperative horn. I can provide the necessary dealership invoice to NHTSA upon request.
