When the car is going from downhill to flat grade, under braking, with some side to side rocking, and under 10 mph, there is a rattling noise under the radio / front passenger area. The rattling seems to cause a small reduction in speed as if something is pulling the car back. It happens only in that situation / car position.
Other than that, car performs normally. I’ve looked under the car and all the underbody covers are fastened on and look normal.
Has anyone else experienced this?
