Folks!

Proud new owner of a 2016 Porsche Cayenne. Car makes really weird clicking/grinding sounds at very low speeds. Dealer replaced the transfer case under warranty. Problem was better for one day. Now. The problem is back. Dealer is saying they have determined the sound is perfectly normal. My question of course is, if it were normal, why go through the trouble of replacing the transfer case. Quote frankly, I'm embarrassed to show the car to anyone anymore. I don't know what to do. Can anyone tell me if this sound IS indeed normal? I've posted it to YouTube. I'd appreciate any assistance you might be able to offer. Much thanks!!!

Replace a transfer case on a 2016...I would be POed.
I cannot hear it over the engine but If the dealer says its normal I would ask them to demonstrate that with another 2016 on their lot.

With chassis noises you may want to try a camera in the video mode. Using a magnetic mount attach it to the the underside near the source. When you have zeroed in on the sound post the clip here.

Why would you be PO'd? Because the car is new??

The sound is impossible to miss. It's difficult to describe the sound so it's possible I've just done a poor job of the description. Try listening for ANY noise besides the engine and you'll absolutely hear it. It could also be described as grinding, stretching, ticking. Try listening again and tel me if you get anything out of it.

I don't believe it is a chassis sound. Prior to Porsche replacing the transfer case, my feeling was that it was the transmission. I know that other cars make the sound because my rental Cayenne did it, too.

But, that doesn't make it normal, it just potentially makes it widespread. I'm at a loss over what to do.

Good advice already given: go back to dealer, have them start another 2016 cayenne and have them explain why it doesn't make the same noise.

When it doesn't demand they repair properly or begin to raise a real stink...

The clicking is clearly discenable and I have not heard anything like that on my 2011 CS nor any of the diesel loaners or the 2016 GTS I have driven. My transfer case was replaced for a metallic grinding& moaning during slow speed turns and now is quiet and smooth at all speeds. The dealer explained to me (also documented in the paperwork) that trouble shooting for a drive train problem involved removing each drive shaft, one at a time, then driving the vehicle around the lot to try isolate whether the clicking is a front/rear differential, shaft connection, wheel bearing, or transfer case. Whatever the cause - that clicking is not normal.

I hear it. Sounds a bit like slowly opening a creaking door.

I hear it. No way that is normal. You bought a new car. It has a warranty. They're responsible for fixing it.

Document, document, document. If you find the need to invoke lemon law, you'll need to show a history of an issue going unresolved.

I hear it also and it cannot be normal!

skiahh

Could it be a suspension creak?

It sounded like it could be steel springs creaking for some reason. Not normal and needs to be fixed, but not necessarily tranny.

Maybe a loose bolt on the springs? Or a loose u-joint? Grasping at straws here, but something's amiss!

If its normal EVERY 2016 Cayenne on their lot would do it also, have them show you on several other 2016 Cayenne's

OK but why? Can you say for certain which component is causing this sound?

KarlJC

No it looks like they cant so far.

My point was if its normal it would be happening on ALL other Cayenne's like his, not just 1 or 2.

that is 100% not normal, they need to get to the bottom of it. best to keep all records in case you have to go further...

I can't believe they would waste your time and fleece you like that. As if a brand new car should make sounds that not even a Nissan Versa would. They must not know what it is and just hope you will go away.

I experienced a similar issue with the Infiniti brand. The dealer informed me that the manufacturer does not reimburse them for diagnosing unusual sounds. This may be a case of they know what it is but will loose money on the fix.

I suspect with the mega $$$ cost to resolve their emissions issues P will become more frugal resolving warranty claims.
