Hi, just purchased my first 2020 CRV 4 weeks ago. It was the model on the showroom floor. I didn't test drive it. Well, took it home and noticed a rattle noise. It's not happening all the time. I have brought my car in 3 times. The tech first told me it's just common road noise. I left feeling defeated. One morning while it was raining and windy, I drove back up and had him drive with me. I also recorded the rattling. He states he could hear it on the video, but not in the car. I will post the video, can anyone help?
