We recently picked up a 2018 Cayman GTS (CPO). The car has ~2200 miles on it and seems to be in excellent condition. We purchased it from a Porsche dealer across the country. Today is the first day I have actually driven the car for a lengthy period of time / distance and I noticed a rattling noise that sound like its coming from the passenger side vent area above 70MPH--albeit this rattling noise could be anywhere in the passenger side rear quarter. It sounds like what I would imagine a bunch of rocks sound like if they were bouncing around / stuck in the vent. When I look in the vent I see that its mostly covered and I can't see anything in there and there is no evidence of any damage. I looked under the car and also in the rear wheel well and can't see any issues or any debris. The performance / temps don't seem to be affected but the faster it goes over 70 MPH the more the noise becomes obvious. Its an unnerving noise and never had this noise in our 981S / GT4.
I read a few threads on this forum and did the diagnostics. I keep the passenger seat belt buckled so its not from there. Seat is forward so not rubbing. I even sat in the passenger seat and could hear the noise as coming from the vent / passenger rear quarter area.
Any recommendations?
