Could it be that the problem is merely oxidisation in areas of high humidity? Like in Melbourne and Sydney and the coastal region where Giannis lives... I'm no metallurgist but why aren't we as a community asking more probing questions?
Perhaps the galvanising of the steel parts in question performed by the OEM supplier was flawed? Is this BMW's fault or the OEM supplier's? Can we knowingly proclaim "cost-cutting!" without any real facts at hand? Yes, there's photographic evidence around, yes, we've got our own (highly credible by all accounts) first hand observations but what I want to know in order to form my own, informed opinion is: where, why and how much?
I doubt that it's an issue with areas of high humidity, as not all cars I saw were from my area. I saw one here, a test-drive F30 that came from up north for the test-drive and then sent back (yes, we don't have an F30 on display due to the melt down of the greek automotive market) and then 3 F20 that were delivered and operated in Athens.
Obviously, I don't have a material laboratory so that I can prove my claims, or test my thoughts. But, I live by the sea and so do many friends of mine with both cheap japanese and premium german cars. None of them had any issues with rust. The lack of galvanisation treatment wasn't a guess. It was what one of those 3 F20 owners told me, when he had his seat frames removed and sent to a workshop to be treated as they should: Sandblasting for rust removal, galvanisation, prime coat and then black paint. They (workshop mechanics) told him that this was a classic case of rust in non-galvanised steel. They didn't know that this came from an F20. Do they have a material lab? No, but they have experience.
That's what I heard and I wrote it here, also stating my source. Someone might find it usefull, and the rest will ignore it. I'm fine with that. It's nothing more than my personal experience and should be valued as that: "personal experience of a random forum member. No photographic evidence".
Yes, it's a defect - no denying this - but defects (and the management thereof) are actually part and parcel of the process of bringing an automobile to market. Not even glorious BMW is immune to the potential for human fallibility.
Sure, everything may show a defect and up to a point it's acceptable. My Clio wasn't flawless and had it's idle revs regulating valves replaced 2 times before working properly, under warranty. It works fine since then. My Volvo had an issues with an ABS sensor that resulted in an Anti-Spin error message and was also fixed under warranty. Both are acceptable, made me angry for a whole morning, had me cursing the swedish automotive industry, but then I calmed down and called it a day. The issue never showed up again.
But rust is a different thing. Rust can build up under the surface of the material and you can only realise it when it's too late. At least in my field it's very common, with reinforcement steel bars rusting inside the concrete (for a variety of reasons) and then suddently bursting out. It's a big problem and it's too late for a small fix.
Yes, the rust in the seat frames I experienced was only on the surface of the material. But my problem is not where it showed up, but why it showed up. Why did I see rust in 5 new cars? Or, in a bolder tone, why did I see rust in all the F20 I saw? That's a question that I am eagerly wait to be answered.
And once again, if I had bought an F30 and didn't want to sell it soon, I'd do what my before mentioned friend did. Sandblast, galvanise, prime coat and paint. After that, the rust issue will never show up again. But it will cost me in time and money, and I can't understand why I have to spend more money on a new car, when I shouldn't.
Instead what we have here is the typical harbinger of doom level of discussion on GCF with all but a very few individuals actually contributing to a greater level of understanding on the issue. It's a free world with free speech - but if you people can't recognise that we have the natural, healthy level of opinion polarisation (i.e. the two extreme views) ranging from, doom 'n gloom, to, how bad is this really, and that sensibility has to reside somewhere in the middle, then I must ask: where have you been for the last ten years? [Don't answer - it's rhetorical, food for thought...]
Sure, but isn't that the nature of automotive forums? Many opinions, some polarised, some down to earth, discussion generated from a fight, from a spyshot, from an opinion, from nothing. It's not as if we are all automotive industry insiders and discuss our little dark secrets.
Why though all the conjecture around the extent of the problem? Out of the 100 000s of F20 and F30s manufactured how many specific incidents do we have on record? No one knows. On the internet a couple of photos in a couple of threads and the next thing it's an epidemic.
Actually, I wonder how many owners noticed this rust. Out of the 5 cars I checked, none of the owners thought to take a look under the seat. Now the one is having it repaired under warranty, one is having it properly repaired at a workshop, one is a test drive F30 and I don't care, and the other two cars belong to the wifes of two friends, so they don't really care.
I've seen 5 F20/F30, all of them had rusted seat frames, none of the owners had noticed it. Maybe I'm crazy...
