My trunk/brake light rattles every time I hit a bump. It sounds like two pieces of sheet metal touching and I can not find anything in the trunk that would make this sound even if i hit it with my fist. This is extremely annoying and noticeable to everyone in the car even with the radio ON.

Has anyone noticed this issue. This is a sedan so I am not sure if this makes a difference. This has been an issue throughout the year and I just want to know if it can be corrected.

Thnak you for any assistance.

 

Do you have tint?

 

No tint. I am not sure how this would change/create a sound.
Perhaps a strut bar will help with the vibration when hitting bumps and potholes.

- Anyone know if installing a strut bar will void the Manufacturer warranty.

 

If you had tint done, they usually uninstall the third taillight to apply the tint. Perhaps they didn't reinstall the taillight properly? Strut tower brace does not void warranty per se.

 

no it will not void your warrenty ... corsport makes a trunk brace for our cars ... check out corsport.com

 

Is your spare tire loose? Is the clamping screw that holds it down tightened? Is the tool holder present? It should be a styrofoam thing that holds your jack and tire iron in the spare tire. Check under your spare tire. Maybe something feel down in there.

Other things could be loose speakers (three on the back deck), loose 3rd brake light, or could be your license plate. My license plate used to make noise until I stuck foam to it. No more sound. Get in your trunk and look up at the rear deck. Try gently tightening every nut you see from below. If one is loose, it could be the source of your problem.
