Upon removing the driver seat belt after a trip today, I noticed the buckle release button was sticking down. I re-inserted the buckle, and heard the "click" sound indicating the buckle was securely fastened. I applied tension on the belt buckle, which released without pressing the button! I searched the internet for recalls, and found the 2018-2019 Honda Accord was recalled for a seat belt release button repair. However, there was no information about a recall for the 2020 model year, which I experienced this issue with. My safety has been put at risk as I am unsure how long the belt buckle has been able to be removed without pressing the buckle release button. I have not yet contacted Honda about the concern. A video is available and this issue is repeatable. There were no warning messages. My vehicle is available for inspection upon request.

The driver's seatbelt assembly generates an intermittent rattling noise, especially when going over road imperfections/bumps. This makes me question whether the seatbelt is going to work in case of an accident. The problem was noticed after two hours of purchase.
