612 Passenger Door Corrosion

The car’s all-aluminium chassis and bodywork are not only incredibly light but also offer other significant benefits in terms of performance both on the road and under braking.

This is from the 612 brochure. Could it be that your car had been in an accident and was repaired?

 

Paul- Anybody with a refrigerator magnet can check. Sales brochures are not always the most accurate source.

 

They're steel for safety, same as the Maranello's. Aluminium does corrode, just not like that

 

Mine had corrosion in almost exactly the same spot. We noticed it when it arrived in the US after my european delivery, so it was 3 months old. Ferrari repaired it under warranty.

They actually offered me a whole new door, but wouldn't guarantee that the new door would be corrosion-free.

From what I'm seeing on here, it seems to be fairly common.

 

Also, the doors are alloy. I know this because I asked about it at the time.

 

Just been out with a magnet and the magnet doesn't stick. So all aluminium looks to be the case.door is not steel.

 

Taz, the brochure is accurate, none of the body panels are steel on my 2008 OTO.

But MoeD back to your question of why this is happening. I don't have it on my car. Perhaps this was a problem on earlier year cars?

 

I have seen this on other cars such as a California

 

I'm thinking this must have been the result of some sort of manufacturing process issue, or perhaps had something to do with where the doors were stored prior to painting. On mine, there was a hypothesis that something corrosive had spilled on it prior to paint, but given the number of doors it's happened to, that seems unlikely-- at least by chance.

Maybe overspray from some process adjacent to where the doors were stored?

 

Nice alloys by the way

 

Paul- Apparently, so. A kitchen magnet does stick to a Maranello door.

 

Don, I just looked at your profile and see you have a 2008. There goes my theory about the year of manufacture.

What is really crazy is that it showed up on your car when it was only 3 months old. Even unpainted wrought iron won't rust that fast!

 

Could the passenger side corrosion be because of the crown of the road and all the crap that gets accumulated in the gutter, and ultimately sprayed on that side of the car?
Wonder if it happens on the "passenger side" in the UK?
Just a thought... Probably wrong...

 

One theory is poor side mirror fitment that allows moisture in.

 

I have an 06 and mine has the corrosion. It is being repaired this winter. I have personally seen corrosion in the same location on three other 612s. All on the passenger side door.

 

That's one reason I think it was a manufacturing process issue.

Well, that and the facts that a) Ferrari wasn't the least bit surprised, and b) they wouldn't offer any assurance that a replacement door would be any better.

 

If always in same spot and happens early on I would look for some type of dissimilar metals causing a galvanic effect.

 

We need Mr. Vin # to start a class action lawsuit. Would this be a first for Ferrari?

Mr VIN # has more powers than he knows what to do with.

 

How long is the factory corrosion warranty? Isn't it something like 8 years?
