Bodywork warranty claims

[rowtietowers]

Anyone been successful in claiming against the 10 year corrosion warranty offered by Porsche for any model?
If so how did you go about it as Porsche are claiming it is caused by external influences such as stone chips which is rather laughable.
Mine is a 2017 718 Boxster but will apply equally to the 718 Cayman.
Any advice appreciated.

Most bodywork warranties only cover corrosion from the inside...

So if caused by stone chips etc will be excluded

But if the corrosion is on the inside of the wings, surely that is my definition of corrosion from the inside - if left unchecked it will appear on external surface of the bodywork. See my fuller update in the Boxster section.

Can you share photos of the corrosion?

A colleague had the same issue with his 981 Boxster. As you found, Porsche UK pushed back as chip damage and therefore not covered. There was blistering on the outer surface of the rear arch. My colleague argued that this was not due to stone chips, but internal corrosion in the seam between the outer panel and the wheel housing panel. A few months earlier, at the 10 year service, the OPC had signed off a body inspection with no comments. Had this been flagged then, he could have taken earlier corrective action. He also had the arches checked by an independent repair shop. They were of the opinion that the source was internal and would have been present well before the 10 year service. In the face of my friends dogged hounding of the OPC and Porsche UK, they finally agreed to a warranty repair, replacing the exterior panels on both sides. Interestingly, while at the OPC, he saw a 718 with exactly the same problem.

Thanks for that and interesting to note and lines up with my argument. My only issue is they may say “you didn’t get the 6 & 8 year bodywork stamps” - I took it out of the dealer network and went down the independent route after the 4 year service. However, firstly there was no corrosion or bubbling at the 6 year period - the corrosion has happened internally and looks like it started within the last year or so.
I will contact Porsche GB on my return from holiday and give them another opportunity to respond but I’m not just taking it lying down.
I’m pretty sure they don’t remove arch liners as part of their bodywork inspection.

The unfortunate thing is that the lip at the top of the rear wheel arch is a haven for detritus which will, inevitably, cause rust. I'm always conscious to wash out that area when I clean the car and I take my wheel arch liners out (not much of one in the rear though) to clean behind them but not everyone is able to do that.

To be honest I think the rear arch is a very poor design - effectively a U-shaped channel which as you say traps all sorts of debris. I always thought I jet washed these areas but it’s virtually impossible to access that area in particular. I always post-wash take the car for a quick run to dry out the underside and the brakes (cross-drilled & ventilated).
This is my fourth Boxster and I don’t remember seeing any corrosion on any of the previous ones.
This one was an ex demo from Belfast bought at 7 months old but I live in the North East of England nowhere near the coast so it couldn’t be classed as a “seaside car”.
