At random times while Im driving I will hear a ding noise. Same ding noise sound as when the trunk is open. Mostly happens when I apply the brake after I have been driving for a while. I feel like its trying to tell me theres a problem but theres no indicator light blinking or anything just this annoying ding that lasts about 5 seconds each time. I would love if theres someone else with this problem that can give me a solution. I even added brake fluid thinking it was that but that did not help.
