I have owned a 997.2 C2S Cab, 991.1 C4S, and 991.1 GT3 before current 991.2 C2S. They all had rattles that would come and go. The current 991.2 has a creaking sunroof. Others had dash or door rattles. If you are really OCD about rattles and will develop buyers remorse because you paid so much for a car with rattles, I'd avoid the 991.

I had one rattle that took me 2 minutes to fix, and now she's solid as a rock.

I'm up to 28k miles with no rattles or squeaks in my 991.1 and she isn't just babied.

There is a frequent crackling sound coming from the rear though, mostly in off-throttle downshifting from high RPMs. It's more prominent in tunnels and under overpasses To not avoid, get a 991 with PSE.

An Observation & Question:

Rattles definitely seem par for the course, at least in this generation of cars.

I had a 981 Cayman S that rattled like crazy from the rear hatch. Liberal application of WD-40 seemed to solve it, at least until I sold the car a year and a bit later.

The sunroof and passenger A-Pillar in my 991 Carrera S rattles also. It does seem to be intermittent and triggered by temperature cycles causing things to expand and contract.

The dealer has some kind of magical procedure to mitigate it for a while (presumably using Porsche Branded WD-40 applied by a qualified Master Technician) but the service folks categorically state I should NOT just go spraying around in there.

I'm under warranty so I'm taking their advice and not messing with it myself, but it's a pain to take it in to the dealer each time the creaking comes back - once my warranty is up I'd like to stop doing that. Anyone know what the magical procedure is? :-)

My 2013 Cab has rattled where the windows meet the top when the top is up. Honestly, it may be related to the terrible tint the original owner put on. Hopefully they go away when I change it.

Otherwise no issues.

Rattles are also a matter of going to specialists. Use a highly directional microphone (with headphones) to locate specifically where it is coming from. Have some experience what kind of sound maps to what kind of specific problem, and how "deep" it is behind the panel (high frequencies get dampened more than low frequencies by obstacles).

Make very sure to tell rattles from squeals. Totally different issues.

WD-40 isn't the prime squeal fix, BTW. There are more specialized friction removers such as teflon, silicone, graphite and others. And you should only go towards fixing a squeal by lowering friction after you have attempted to fix it by holding down the offending part in place. Sometimes it is best to do something in the middle, which is put a highly flexible glue that also builds up, thereby allowing some movement but prevent noise, e.g. 3M 08061.

As people mentioned, avoid cars that have rattle-prone components that face the outside, such as sunroofs and hatches. The fact that they are facing the environment makes fixing noise issues much more complicated because you need to preserve the ability to keep water out. Also, removing such a part requires a garage for the duration of the game.

This is one of those areas where the dealer might be at a disadvantage. They might happen to have somebody with experience in the area, but if not it is a guessing game.

My 2013 C2 was perfect not a peep...My 2015 GTS one in the driver door, I will search and find and fix, I hope.

986 & 991.1 that I used to drive had rattles. 991.1 only rattles at high speed, but 986 was a rattlesnake in essence it rattled everywhere. I never bothered fixing them because they were drained by pse, loud music, & my grin most of the time.

From what I see, most cars that use heavier frame that are flexible without using light weight material for the interior, has a good chance of developing squeaking / rattling. Older exotics had this problem too, but not newer ones with plenty of carbon fiber.

Same! Can't find it. Especially bothersome when it's cold

Louder than a Mercedes sedan yes.

Rattles no. None in my 2012.5 Cab.

I've been one of the noisier complainers about rattles - my car had 5 simultaneous rattles when I got it including one that buzzed like a saw.

I got most of them tamped down but still had one in the dash that was making me hate the car. I literally started thinking what I should do next - order a new one, downgrade to a 997, etc.

I'm happy to say I found and fixed it, and I'm now in love with the car as if it were new...after 2 years of rattle annoyances.

My advice would be don't avoid the model because of rattles, but make sure you test drive one thoroughly. If it's convertible or Targa, drive with the top UP. Find rough textured pavement, etc. If there are any rattles you can't live with, make them fix them to close the sale.

My 991.2 has zero rattles. I am actually shocked.
My 997 had a dash rattle and my Turbo had a sunroof rattle. Just lucky this time.

Two years, still looking and listening. Nada. Too loud inside- drive the wife Lexus.

IMHO, loud and rattles aren't the same thing. Rattles are a fit and finish problem and as a potential buyer, I find this thread interesting. My current car has over 150,000 miles on it and I live in a horrible area for roads and my Audi has NO rattles at all. I am not a fan of things rattling around in cars to be honest. Exhaust noise and motor noise is one thing, but rattles are a quality issue, IMHO. All that being said, I am buying a Porsche anyway.

No rattles. 2014 991S
