I noticed today some strange markings on my rear tailgate on the inside that are almost symmetrical left to right. That makes me think that something is wrong. I don't seem to be able to make them go away. Any idea what they are? I feel like a trip to my dealer may be in order.

I'm a plastics engineer by trade, I've seen this before.

I work for an automotive supplier (interiors)

Its a molding defect in the plastic panels.

There was mold release on the part, its a chemical used in injection molding to get the first parts to pull off the mold.

Its slippery and molds into the first couple of parts.

They are scrap parts, it should have never been sent to be used in a vehicle.

It may have not shown up right away, but this stuff blooms to the surface after time.

Take the Jeep back and have them replace them if you are under warranty.

That makes sense to me since I have one of the first 2019 Cherokees. I've seen other oddities in my car like aluminum hose clamps on stuff underneath and areas where plastic seems to have been trimmed. I need to get around to documenting all of it to see if its normal or not lol.

So I brought my Cherokee to the dealer today and they gave me a bit of a hard time but they at least agreed to have a tech look at it. I didn't have time to drop my car off so I made an appointment for next week. Both the in-processing guy and the manager had never seen or heard of this ever happening on any vehicle ever. So I hope they will agree to replace it under warranty.

So a quick update on this. The dealer looked at it, and just like me they couldn't get the marks out. To replace the part unfortunately, you have to replace the entire tailgate since according to them it is a full assembly not sold separately. The parts cost is like $1200 and due to the dollar amount they needed to get Chrysler approval first. Unfortunately Chrysler has denied the warranty claim saying it is not a defect.

Even if they did replace it they said they would have to repaint the new tailgate and it would not perfectly match the rest of the car again, and transfer the glass and other parts over, etc., it is a real hassle. So now I need to decide if I want to live with it or call their hotline to pursue it further.

I would check with a few different dealers. What qualifies as a warranty repair seems to be up for interpretation sometimes.

Worst case, it's just a cosmetic defect and you get to be part of the blooming plastics club. I hear it's quite exclusive.

I picked up some 303 aerospace protectant and wiped it on there and it totally covers it up. So I'm just going to live with it. I just need to put some protectant on there every few months and it looks good as new. It's easier than trying to fight for a replacement tailgate and all the risks associated with that.

I would try one of those products which restores vinyl to original condition. Not one that only coats the surface only to wear away shortly.

The takeaway here is another FUBAR by Chrysler. Why can't you get the plastic panel separately from the entire tailgate? Kind of how I found out that the blue removable clips that hold in the plastic panel surrounding the stereo cannot be purchased separately from the panel.

I talked to another guy on a different forum who designed interior panels for GM and he said that it is definitely not mold release. So I'm not saying you are wrong, just that we may never know for sure.

That's fine. Without actually seeing your panels in person, its my best educated guest. I've only been a injection molding plastics engineer for 8 years.

There are several reasons why this could have happened. Another is a product we banned within Ford because of this issue, I assumed FCA would have banned it with their suppliers also.

Rereading your post where the dealer tells you they can't get the interior panels separately is laughable. There are multiple color options for the KL interior and they literally install the interior after the Jeep is painted at the assembly plant. Those parts are 100% available as replacements. Their parts guy is either bad at his job or didn't want to look.

Either way, if 303 covers it, its a molding defect. I'd push for replacement, but I'm an automotive engineer and that stuff makes my blood boil because of what it represents, low quality.

If they won't replace it without replacing the whole tailgate then I don't think I will. I don't trust them to paint a new tailgate and have it look nice. And they have to transfer the glass and all the other parts to the new tailgate. I have had similar done before and it always turns out poorly.
