What's causing this crack on both sides of my Jeep? It's the seam between the rear quarter panel and rear corner. Thank you! I am hoping this is something Jeep will cover under warranty...

Is it just the paint? It is pretty deep.

That's a welded and sealed joint.
Definitely should be covered by warranty.
When they fix it, they should treat for corrosion inside that open joint before they reapply the vinyl sealant.

If you want to look at it to see what's going on, remove the tail light assembly to see the welded tabs.

That sure doesn't look good. I'd be pulling the carpet sides and lights to get pics of what's going on before heading to dealer.
Something's weird there because it's two separate spot weld robots and two separate sealer robots that put that area together for both sides.
Makes me wonder if that rear end was repaired before you bought it.
Do you have any BODY mounted sliders or skids that may be taking a beating?

Do you have anything attached to you rear tailgate? IF so I would remove it before taking it in for warranty..Keep us informed on the outcome.

If I had to guess, I would say that has been in a accident before and had some bad repair work done.

We see this on JK's with certain imported rear bumpers that do not clear the tub in the corners. The JK's body on frame design uses rubber bushings to help you "float" on your frame. When an aftermarket rear bumper (frame mounted) makes contact with your tub (bushing mounted) you are creating a bumpstop with your bumper. Check underneath the rear corners to see if you've been contacting. If you have, that's most likely the cause. A few import bumper brands are notorious for this.

Looking at your first photo, it appears that your rear bumper does in fact come UNDER your tub in the corner. Could very well be the culprit.

Could very well be the bumper, but I noticed in the picture it looks as though the metal along the side where the tail light is is uneven. It almost looks like someone tried to Bondo the area, but didn't sand evenly before repainting. Looks more like a repair job to me.

I have read all the comments. I bought the Jeep brand new with 14 miles on it, so the idea of it being in an accident before I bought it is near impossible. Also, the bumper is made by Warn (not a cheap import). If the bumper caused this damage, I assume I would have a claim against Warn. The swing arm of the tire carrier is attached to the bumper itself and to the tailgate. (Image attached) 4 wheel parts did all the work and they mentioned never seeing this type of crack. The crack is happening on both sides of the Jeep, which also makes me believe it's a Jeep problem, not a bad repair job by Jeep from the 14 miles it had on it before I purchased it. (If the Jeep was repaired and sold new, we are talking about a huge claim against Jeep itself)



What are my options here? If this is a Jeep problem, they will repair it. If it's not Jeep's problem, will this continue to happen, even if I have it repaired? Should I just put Crusher corners from PSC on the Jeep and move on?

Have you looked inside to see what's up with the welded tabs?

But I don't think you have a case with Chrysler with a rear end modification / nor Warn either They sell these bumpers as off road parts for off road vehicles and that is up to you if you chose to turn the vehicle from stock to off road . just my take on it . Looks like you modded to soon if you want the warranty to stand up . Hope you get help on it but will be interesting to see who eats the cost . Maybe you backed into something and insurance will have to pay

looks modified all over to me, / lifted / bumpers/ ... nice looking though


the crack is opening from top down so it almost looks like a weight issue on the weld

Best wishes on a fix! btw : Some times they go for repair if they fall off the truck and still new . 14 miles means nothing
and they don't even have to say it was in accident either ( way back in time I bought a truck new , and found out it was hit in tailgait no miles on it . waxed it and the wax stained the paint due to improper paint job they repainted a new one but
