Horn Assembly problems of the 2019 Chevrolet Traverse

On June 20, 2019, I bought a 2019 chevy Traverse with the understanding that the vehicle was in good condition with no defects. On July the 18 we took vehicle to the service department, due to there was a very strong odor when inside the car. It was causing bloody noses and breathing issues for my family. The smell was so strong that it could be tasted. The dealership took about 15 to 20 minutes to diagnose car as nothing wrong with it. We took it home. On August 1, 2019, the vehicle starts going crazy with electrical issues. While my wife is driving with my kids the horn, lights, and emergency lights start turning on and off and there was a loud ugly sound from the engine. The car had to be parked to and I had to go drive car home due the unsafe conditions of vehicle. As I looked under the hood, I could smell a burning smell and smoke coming from the engine. So we took vehicle back to dealership. After being on the shop for about a week , we got our car back and according to dealership it was fixed, along with the smell they told us it was a rare situation but that we had mold and mildew coming out of the ac unit which was causing the odor and hence bloody nose and breathing issues. They also found that the battery was throwing sparks and was burning electrical wires in the engine. At this point we just wanted our car back. The following day my wife and kids were put in a dangerous situation due to defective car, while driving the Traverse it turned off on them while on the highway. My wife and kids are traumatized and scared while being put in these dangerous situations. Unfortunately, your vehicle has not performed well and is not safe even after it was made clear to us that it was safe and fixed.
