Since about a year ago, my 2105 RC350 Fsport started having minor rattling in the headliner. The sound seems to come from just in front of the sunroof.

When I lightly hit the headliner just in front of the sunroof I can hear the rattle. The rattle also happens when hitting bumps in the road. It has only seemed to get worse over the last year. And the ARK exhaust I have can create the rattle at certain RPMs as well.

Any idea what could be causing the rattle? I suspect it would be a loose screw(s). Does anyone have pictures with the headliner removed? I will most likely just have the dealer look at it, but if its something that would be simple to do I could try, as well.

 

The ES 350's have an issue with sunroof bolts. It is a TSB with Lexus. Might be worth a call. Mine drove me crazy until they corrected it. Kind of like a squeak / rattle noise. It would go away if I pushed up real hard on the right front of the sunroof frame.

Does not sound like the same issue, but could possibly be related.

 

Actually sounds pretty similar. I could also make the rattling go away by firmly pressing into the headliner in front of the sunroof. I'll update if I find the actual issue.
