Could well be, but it would be very unusual for a 2018 car, unless it had done a "starship" mileage. If it sounds "tinny", look at the thin aluminium heatshields underneath, which can sometimes come adrift and create a vibration. also fuel pipes underneath sometimes vibrate agains the floor, seems to be a common problem, not clipped correctly to the body.Get underneath and start having a tap around. Get someone to start it up, & get underneath and see if you can isolate the problem.
