Sticky knobs!!

New question.
The volume rubber rotary control knobs in my 991.2 for the infotainment system feel a tad "sticky" to the touch. I know that kind of rubber can deteriorate over time. Is that a common issue? Will Porsche rectify it under warranty?
Thanks
 
Quite a bit on the forum regarding this subject. You can search "Sticky Knobs" and see what other have recorded. Seems like hand sanitiser and/or isopropyl alcohol are the preferred cleansers. It's doubtful extended warranty will cover the defect, but by all means give it a go! 🤞🏼 😆
Regards,

Cleaned the neighbours sticky one with oven cleaner / degreaser - pull off the knob, spray with oven cleaner, leave for few minutes and wash with warm soapy water.

Done this on several cars now. Looks like newer cars go stickier earlier and thinking the manufacturers have changed the composition of the plastic.

Hope this helps.

Thanks - normally I would try that - but:
I took the car to a dealership today.
They said that it is possible that the knobs will be covered by my warranty, but it will need to go through "a process" - so probably best I just get them to review it when its in for service next year. There's no rush - but I think if I try and clean them myself it may invalidate the cover.
 
For warranty claim, suggest claim now (don't delay until service next year) as standard legal requirement to notify warranty claims as soon as reasonably known and to reasonably prevent further damage / deterioration.

Thanks - I have emailed the garage to tell them that they had said I could leave it until the next service (so at least the point is registered) - but do I need to actually contact the Porsche Warranty company themselves? (I have never used a warranty - so not sure of the process)
 
Assuming you have the official Porsche warranty, it looks like you need to formally notify your OPC of the fault and they have to assess the defect and formally respond.

You may have further rights / redress if you purchased it recently, such as Porsche Approved.

As looks like a low value & quick change part the OPC may do it as a goodwill gesture with the service. Had this with wind deflector mounts for a relative.

Depending on your emails to date, ask them to confirm by return email that this will be rectified at no further cost to yourself and won't be impacted by waiting until next years service.

Otherwise, suggest you send an email titled 'Warranty Claim' and say following your previous communications you are writing to formally record a claim for the rectification of [describe fault] and ask them to confirm that this will be at no further cost to yourself and to advise how this will be rectified.
 
Thanks Marc,
I did write - and this is an extract of the response I have just had back.
I am somewhat surprised, given they didnt even look at the issue, and I am sure they have not been cleaned in the way they have suggested:
Unfortunately, the replacement of these would not be a warranty claim. They function but feel sticky to the touch. This would be an caused by an outside influence, most likely a cleaning agent that has degraded the rubber.
I did highlight that the issue is a known one for the rubber coating used - but the dealership have just ignored that.
They have said replacements are £32 + vat per knob!!
I will probably just leave them for now - or maybe try some of the other suggested cleaning techniques to remove the rubber layer.

Thanks - I did try - see the feedback at the end of this feed.
 
Told you to sit down when you got the price.

You may be able to find some cheaper ones from the likes of Ali Express or Alibaba and they're probably made by the same people.

Unfortunately, many of us have experienced similar type responses from OPCs.

You may want to escalate to the Principal of the OPC and highlight that that it's simply not fit for purpose and how unsatisfied you are with how this has been handled, especially given the that the lack of examination and onus upon them to demonstrate such claimed improper cleaning.

It comes down to how much time you want to spend dealing with this. Otherwise, clean it yourself and enjoy driving your Porsche.

I had similar with bike grips and they come up with the same improper cleaning agent crap, then ended up replacing them at no cost when I said my piece.
 
I had a similar issue with my 997.2 PCM knobs which I think are the same as on the 991’s PCM.
After cleaning them to remove all the old paint I sprayed them with black Plasti Dip and they were good as new.

I am a bit shocked by the whole thing.
A Porsche warranty isn't cheap. And they know the maximum they would have been in for would have been about £100 (including their margins), and that would have given them so much good-will.
And I do think if I am making a claim, they at least should have said they will inspect it, and give me their findings, rather than just speculate without having looked.
The dealership has actually had bad reviews recently. However, when I went in, it felt to me they were making a real effort - so I am surprised to have had this response back.
I may leave it for now, and highlight it when I take it in to a different dealership, as I dont think I will go back to the first one!!
