Corrosion Problems

[450chim]

HI i'VE GOT A MATE WHO'S BEEN THE PROUD OWNER OF AN ALI BODIED XJ.RECENTLY HE'S NOTICE VERY BAD CORROSION TAKING PLACE AT MOST OF THE PANEL EXTREMETIES AND THE EDGE OF THE BOOT LID.HAS ANY BODY ELSE HAD THIS PROBLEM IF SO HOW DID YOU FIND JAGUAR TO DEAL WITH.

Firstly stop shouting......
Secondly it cannot be corrosion the clue is in the word aluminium.
I understand Jaguar are aware of the problem & have been repainting cars where necessary.

Aluminium corrodes, but it doesn't rust.

I'm now on my second ali bodied XJR.

The first (2003) had small signs of corrosion around the edge of the boot by the rear window and a couple of small bubbles on panels elsewhere, nothing serious just little tiny bubbles in the paint.

My current one (2007) has some corrosion on the front edge of both rear doors right at the bottom (about a centimetre long along the seam right at the bottom off the door), and the join between the boot and the chrome jaguar strip is showing some corrosion inside the joint (this is all along the joint just in above the chrome).

As yet I've not taken the car to Jaguar, I'll ask them to look at it when I put it in for my first service in a few thousand miles.

I'm hoping that as the car is just over 3 years old they should honour their corrosion warranty and fix these blips but they seem to differentiate between up to 3 years and 3-6 years in what they cover. Something to do with surface and perforation or something.

Guess I will have to wait and see what the dealer thinks.

Aluminum will corrode it that's we refrain from using it in certain offshore applications. The obvious problem is a paint system break down which should prevent the Aluminum reacting with surrounding athmosphere.Also I suspect there is a preparation issue with the substrate. However I deliberately kept the question simple.

Good news is that Jaguar are aware and are repainting, must be honest the response he's had up to now hasn't been that good from Jaguar Customer service.

I was simply wondering if any body else had any better success.

PS I've turned the volume down

It's been previously suggested that the X350 body oxidation was due to steel rivets being in electrical contact with the aluminium bodywork. A more recent and reliable source indicates the paint bubbling is due to minute traces of steel from the panel presses being trapped in the aluminium sheet which has not been cleaned off prior to painting.

The areas affected seem to be the leading edge of the boot lid, wheel arches and door bottoms as well as the a/b/c pillars.

I've tried to find out more as I'd considered buying an X350 myself - aparently it's supposed to be only early cars that are affected, but that of course could is no gaurantee thet newer cars won't be in the future. As far as I can see it's not particular colours or build dates either so it may be a question of luck whether any car has the oxidation problem occur.

Jaguars have a 6 year paint warranty so anything registered before 2004 is no longer covered, but rather worryingly is that even repaired cars are bubbling up again soon after repair - I know of one car that's been repaired twice and one PHer postes he's had the same area painted no less than 4 times - so obviously a quick blow over whilst leaving the contaminated bodywork underneath is not a reliable cure but of course it'll get Jaguar off the hook until the warranty expires.

I remember a similar problem with some stainless steel equipment that we had made at the place I first worked. We were doing some testing on corrosion problems with electronic components. We needed some racks making to hold the samples in the test humidity chambers. After three months of testing we opened the chambers to find all the stainless steel covered in rust. This all turned out to be from the tooling used to make the plate. The stainless was fine underneath but suppliers had to totally change their manufacturing process to make the stuff clean enough for us. I guess Jaguar's suppliers are having a similar problem.

I have just submitted my 56 plate S type to jaguar for corrosion on the bonnet. The process is that the dealer takes a photo or two and sends it to Jag Central. They then make a decision on the photo evidence.

Here is my own photo evidence







Jag Central have refused the claim on the basis that there are stone chips in close proximity to the bubbling and that water will have got under the paint via the stone chips and travelled to the corosion area.

I think this should be challenged.

I think you should stop wasting your life and get it repaired before it degenerates. Any bodyshop would charge around £150/200 to do it.

Does the current XK/XKr suffer from the same problem? or is just the XJ?

[bketype]

Ref Corrosion on the XK
I have a 2006 launch car , slight corrosion on the door after two years, fixed without quibble
Now I have some on the boot and rear wheel arch.

I've been in aviation ( most planes are ally) and Was advised by an expert in the field this may be caused by the incorrect preparation of the body prior to painting.

I have heard that Jag is booting some claims into touch ( despite the 6 year corrosion warranty) under the grounds that the corrosion was caused by water ingress caused by stone chips.

I'm awiting Jags Authority to repair , via my dealer .In the event I have a similar rejection, watch this space

How do you not get stone chips with the state of the road etc

Other than leaving the car in the garage, then the damp will take effect

As an update to my post above, I took my 2007 XJR to the dealers and after talking to the receptionist and explaining that jaguar have a 6 year warranty for corrosion not just a 3 year one, I got through to the guy who deals with it. He took the pictures and sent them away. I chased them up a few weeks later and the work had been approved.

So both rear doors and boot lip heve been resprayed a few weeks ago. Nice job too! So the jag is back to being spotless again.

Pity you had to 'chase him up after a few weeks'. I expect better from a dealer.
