Since ownership of the vehicle (2023 and a CPO Platinum Wrap), I have had to replace a single horn, or both horns three times with local Hyundai dealerships. mostly the right horn would fail, then the left.

   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.

   Horn failure, confirmed by Hyundai dealership. No warning or indication of failure. Went to use horn in a safety situation when I needed it, and it was non-functional. A huge safety risk for myself and other drivers on the road. In doing research, this is a known manufacturer defect, with most owners having to replace low and high horns multiple times due to failure. The horn units apparently due to placement and design fill up with water, which leads to failure, again,…

    12v connector for phone charger melted my phone cord. Reported to Centennial Hyundai Las Vegas and High Desert Hyundai Kingman Az. Both service departments said my vehicle cannot detect the problem because I purchased a substandard plug-in. I have worked as an operator of high voltage electrical systems. I understand in some circumstances that a system cannot detect a fault, however the company is still responsible for the fire it caused. This is unsafe and can cause serious…

    I have a problem with the horns on this vehicle. The horns have been replaced by the dealer 5 times so far and they are out again. THE HORNS LAST ABOUT 1 TO 2 MOUNTHS. There is no warning that the horn stopped working, and if it's needed in an emergency to avoid an accident and doesn't work, myself and others could get hurt. This is ongoing problem that should to be addressed.
