Corrosion in Aust 2015 GC

Hi, only had the GC Limited for a couple of weeks & generally love it.
However, having a look around, there seem like a lot of aluminium that is badly oxidised, as in I can wipe a significant amount with my hand.
Is this common & does anyone see this as an issue?
Cheers, PeterS

Re: Corrosion in Aust 2015 GC

Hi Peter
I have a 2014 overland delivered to Perth and I have no sign of corrosion as shown in your pictures. Looks like the engine bay was hosed down or left on the docks when a winter storm has blown in??
Doesn't look normal to me.
Cheers
Mike

Certainly doesn't look normal as in "finished" metalwork.

Any exposed metal should be treated with anti rust/anti corrosion surface treatment to prevent degradation.

No idea what happened to yours but a strong alkaline wash will affect it like that.

As an aside, I cringe when I see ads on TV for 4WD's (all brands) driving on the beach and into the salt water wash. I always wonder what they did with the vehicle and were they sold as new or as a demo. Do they disclose "abuse"?

Probably not.

Re: Corrosion in Aust 2015 GC

Thank you gentlemen.
I will take it up with my local dealer.
This has really soured my enthusiasm for the product.
Not sure what the solution should be.
Cheers.

It's only a matter of time before bare aluminum will start showing signs of oxidation. However, your pictures would indicate that something got splashed on those components. You can even see the stuff on other non-aluminum parts. Looks like salt to me... mine is the same way after 2 winters worth of driving on Wisconsin winter roads. Not much you can do about it unless you want to get busy with a hose and scrub brush.

My guess would be that any vehicle used for testing (or TV commercials) is not sold to the general public.

One of my neighbors works for the company that did the HVAC controls for Chrysler. He brought home a Chrysler 300C they were testing months before they started showing up at the dealers. He let me take it out for a drive because it had the Hemi. After the drive he told me that the car was the third hand built pre-production prototype of the 300C and it was insured for $3.5 million. Had I known that I may have passed on the drive. I asked him what they did with the car after they finished testing. He said Chrysler takes them back and destroys them by crushing them.

Re: Corrosion in Aust 2015 GC

This may be salt corrosion left without cleaning. To get that high up (air-con) it may have gone through deep salt water. I hear some people have been allowed to test drive unsupervised for a few hours. How many kms did it have on pickup ?

Hopefully the dealer will help to "make it good".

I live in Canberra, so no salt water here.
Only had 50km on it, I specifically stated that I wanted a new car, not to have been used as a demo, no previous repairs. I'm very particular & would never drive my car on a beach & always garage it.
Sent the pictures to the dealer & awaiting a response (it has been 5 days).
Cheers.

What's your build date?
Could be salt residue from moving the car around Detroit and Baltimore prior to shipping during the northern hemisphere winter.

Hi there, the oxidisation you have on the aluminium components may look bad and unsightly, but there is an upside.
As another contributor to this thread stated, it would have happened over time anyway, but it is surprising that it has happened so quickly.
The oxide film, once fully established, will seal the aluminium from the oxygen in our atmosphere, an the oxidisation process will stop.

My guess is that the vehicle was given a hot wash to remove the wax coatings often applied to export vehicles transported by sea.

I work in the aluminium industry, and part of the anodising process we use is a hot water bath to Rapidly advance a natural oxide film on the metal to form a protective surface layer.

I don't believe that you have anything to worry about. Removal of the oxide without treating the bare aluminium afterwards will only result in the oxide reforming.

If you are going to 'clean' the metal, I'd suggest applying a spray film to protect it.
CRC has a wax based product called 'soft seal'. It's very good and won't affect any other components of the car. I have parts at home that I machined years ago, and under the soft seal the metal is still as bright as the day they came out of the mill.

Pat.

Hello jeeppete916

By looking at your pics I would have to agree with the replies above stating export salt corrosion during the vehicle transportation process from the USA. Nothing to get truly worried about but, the disheartening feeling you will get once first sighting it just after spending a good fortune buying the vehicle.
The Gentleman calling himself P4tr1cK (post above) is correct to suggest by using the wax product called "soft seal".... There should by similar products online as well if you cannot find it in Canberra. I haven't used this product before, but I remember my father (Metal Polisher) & also father in law (welder) both use to comment about this kind of product when they were around during their occupations etc.
Once you find it, go one step further...Take it to the dealer with the receipt for reimbursement, and kindly demand to have their service staff work on cleaning it since the vehicle is under warranty. In my book, and I'm sure all others will agree, is when you purchase a new vehicle one would expect to buy it in mirror finish condition both inside & out etc. Should the dealer play stupid, write to cars guide . They are good at embarrassing dealerships who don't live up to their reputations & promise...
Rest assured, JGC are a beauty to have...I have 2 jeeps myself...

Cheers
