I was driving home from getting groceries when all of a sudden the vehicle starts to make a loud noise from the engine (no warning lamps/lights or any messages popped up.) I proceeded to go home and call my husband and ask for his help with the problem. I recorded a video of the car and sent it to him, and he said that it sounded like the engine is knocking and told me to shut the car off and call the dealership to further discuss the situation with them. After calling the dealership they towed my car to get it diagnosed. It has been a month or so now since leaving my car with them and they still cannot diagnose the issue.
