OXIDATION!

[Angler]

I am very concerned. I picked up my NEW 2024 Grenadier from the dealer two weeks ago and about 4–5 days later I slid underneath to check out the cool factor and familiarize myself with the vehicle and I saw oxidation all over the transfer case. Then, I looked around and it's on the oil pan, alternator and every other aluminum part on the underside and engine compartment. I called the dealer and need to set up time to take it in but wondering if any of you have noticed this on your Grenadiers? I haven't had it near water except for a little rain the other day and the oxidation was there before then.

It’s pretty normal on aluminium components, but yours look particularly furry. Maybe it’s been washed with something that reacted with it?

When you say new, do you mean new build or newly bought?
Some vehicles being sold as new are over a year old. That is plenty of time for the oxidation to begin.

It is a 2024, newly purchased with 50 miles on it. I need to look at the build date but yes, it could be over a year ago. I had a 20 year old F150 that I used to drive on the beach in salt water that never showed a sign of oxidation. It's pretty sever and it's all the way up under the hood on the alternator. This can't be normal.

That’s not normal and it’s the first I’ve heard on this forum. Looks like a pink chemical has reacted to it. Can’t think of what fluid is pink in the engine?

Not normal as it relates to other manufacturers. Have dealer get it dry ice blasted. Probably needs a sealer after that though. Not sure on that part.

The truck may have been on a RoRo through a storm, and left unwashed at the dealer lot for a long time.
