Hi,
I'm new to GS'er and was recommended by a friend who works at one of the Motorrad dealerships.
I've done a search but can't find anything specifically to do with rust problems on GS Adventures, so am hoping for a bit of feedback from the members.
I've been riding for over 20 years and have never had a spot of rust on a bike, even though most of them were parked outside day and night. This is my first BMW, it's garaged every night and there's a significant underlying problem with rust on the rear subframe.

I bought a 2015 GS Adventure from the Park lane dealership in Oct 15 (actually I bought 2 and a 6 series, so spent £75k that year with BMW dedalerships).
The bike is garaged every night and I only use it to do the 100 mile motorway round trip to see clients in London, so it has an easy life.
Last Feb/March I noticed several rust spots appearing under the ppc on the rear subframe and took it back to Park Lane...typically it was out of warranty, so they told me to take it to the main UK service centre in battersea to hopefully agree a good will gesture, but i couldn't get an appointment with the manager at Battersea until June.

Long story short, by that point the rust had worked it's way further under the ppc so when it was washed professionally by my local garage pretty much all of the ppc flaked off the rear sub-frame. I chased BMW from June onwards for progress and they didn't get back to me until end of Nov, so the exposed frame now has surface rust over it's entirety.
They finally booked it in to the service centre in Dec and have now dismissed it saying that it hasn't been maintained properly ignoring the fact that they have strung it out for almost a year.

I'd like to hear from anybody else who has had problems with rust on the frame or if anybody has experience of dealing with BMW UK on inherent problems & goodwill gestures.

My next port of call is to write to MCN, etc voicing my disgust at BMW's handling of this and lack of customer service.
I'm also organising an independent engineer's report.

I'm happy for practical feedback from any members who work for BMW.

Thanks in advance.

Redmonster...thanks, that's really helpful.
I'm suffering from the same issue as him on the swing arm cover as well.
 
Not even a small one?

I fought them for 2 years as mine was rusting before the 500 mile first service
I got nothing
So ended up stripping the bike down and doing it all my self.

When you say “washed professionally by my local garage” are you talking about a hand car wash?
 
Motorway riding is worst for stone chips and that is likely where the rust started. I’m not a big winter rider but have had bikes of all marques and without exception everyone has had corrosion somewhere within 3 years, usually from stone chips or road salt in hidden places.

Never tried to warranty any of them as to me it’s wear and tear after that long and if from stone chips etc. It would not be hard to remove the subframe and sort it yourself when bmw say no, which they likely will.

Spoonz, they have and I think I'm resigned to having to deal with it myself but it doesn't mean I shouldn't make a point of it to them in the hope that they'll take it on board and it'll help others further down the line.
It's funny that it's just the rear sub-frame and not the main frame...the local garage that work on it are classic bike restoration specialists and they were gob-smacked by how thin the layer of paint was on the rear frame (NB paint not ppc in their opinion).
I went out for a ride a few weeks later with some guys from the nearby Motorrad dealership and there was a 6 month old GSA there showing signs of rust spots already.
 
The rear subframe does take a pounding from stones flicked up by the back wheel. Many bikes have ally subframes so it’s less of an issue. My 14 has a tiny bit of bubbling on the cylinders but no paint issues whatsoever elsewhere.

I did read somewhere that black painted engines and subframes were more prone to corrosion. Is the subframe black or silver ?
 
...Is the subframe black or silver ?

Black...yeah, I've seen some of the silver frames and they appear to be properly powder-coated so pretty much zero chance of rust under the finish unless it gets damaged.
There weren't any notable stone chips, BTW...same as the thread Redmonster highlighted above where it starts around the weld joints and some random spots under the (otherwise perfect) paint finish.
 
I applied Gyeon Paint Protection to sub frame, engine frame and shaft drive arm when I bought it 18mths ago, and am about to re-apply a sealant (this time gtechniq CSL). I'm hoping this will give it some protection. Will let folks know in another 18mths!

If you don’t intend changing your bike for another new BMW, deal with it yourself and get on with riding and enjoying it. If you intend to purchase a new BMW bike sometime soon, give them a combination of agro whilst cannily dangling a carrot that you’re open to a way forward to a favourable resolution. (Your bargaining chips are limited as a 2015 bike is getting on in age)

The second option clearly keeps you on a BMW and riding probably the best all around road motorcycle but also keeps you with a marque which has now a terrible reputation for build quality.

My 2017 GSA was pampered but it suffered subframe corrosion and engine corrosion. When I got rid, the engine corrosion could only be seen with a magnifying glass. But it was there despite the bike being cared for.

Edmund, it's a fair point...when I bought it I thought that this would be the first bike i kept until i ran it into the ground, but this may well put me off for life. Essentially it'll come down to how BMW deal with it...if they pull it out of the bag, I'll continue buying them in the knowledge that they'll always have my back, but from the comments I've seen on here so far that's looking like a remote possibility.
Funnily enough, I've driven BMW cars for the last 10 years and apart from the odd issue, they're fairly bullet-proof and the dealership customer service is second to none.
Their attitude to this could stop me buying their cars as well.
 
In my experience the after sales backup is largely down to dealer attitude. One dealer will say “ manufacturer said no” yet another will get a yes. Had this with Aprilia bikes who have the shittiest dealer network of the mainstream marques. I suspect the no often comes from the dealer and the manufacturer was never asked. I would try elsewhere before giving it up as a lost cause.

On my Aprilia I had clocks that fogged to the point of being unreadable nearly all the time. Dealer said no as Aprilia said it’s not a fault. Next dealer replaced 3 under warranty as and when Aprilia updated the design for the issue. They said Aprilia never questioned the claim so I think the first dealer lied.
