Alarm not sounding

Hello, I’m Pete from the Car Genius team at RepairPal. I’m sorry you’re dealing with this concern on your Kia Sorento. Based on the information provided with how the chime/alarm stopped working for your turn signals, back up sensor system, blind spot system, and seat belt feedback, these are all most commonly linked together with the chime system and can be caused by an internal electrical fault with a component like the body computer itself or a seperate chime module which some models have. The best thing to do is to have it properly diagnosed to pinpoint which component is causing this concern so it can then be determined which type of a repair is needed to resolve this concern.
