Folks i bought honda Fit back in march this year it is the gp5 version 2015 with a 40,000 mileage, i have been facing issue in it , when ever i cross a speed breaker 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 ?

i’ve not but recommend u sandwich a piece of hard foam between the lamp and bumper to isolate. GL

Yup the car had an accident from behind when it was with the previous owner (in japan) and its boot was repaired and painted but when i bought the car it was soundless , recently i have experienced the noise.
