Folks i bought honda Fit back in march it is the gp5 version 2015 with a 40,000 mileage, i have been facing issue in it , when ever i cross a speed break or bumps i hear a sound from back, after inspecting i found that the back light makes the sound while touching/ rubbing the bumper, i have adjusted the light many time but after sometime the sound again come back however i havn’t adjusted the bumper.Anyone experienced the same ?
