“The car horn stopped working very suddenly, without any prior warning, while I was driving. The car has around 36000 miles on it, so the horn dying out was a surprise. Driving without a functioning horn has also become a safety issue. I have an upcoming appointment with the dealership to diagnose and fix the problem.”
