Straight white marks on matte paint (on roof)

Could it be some type of tape residue, which would explain the liner lines.

It is some type of tape residue. I believe it is from the plastic paint protection sheets from shipping. I have it on a couple of spots on mine as well. Mine is so faint it is hard to see. I need to see if some WD-40 will remove it.

We had similar marks/tape residue on my son's new SX Prestige. We used some "Goo-gone" and immediately rewashed that area and haven't had a reappearance of the residue.

That makes sense. Anyone else tried a way to remove the marks that was/was not successful. Is Goo-gone safe?

Also, I went back and check my previous photos after washing my car and these lines were NOT present until now. Why would I just now be seeing these? (I wash it every week for the last 2 months)

Maybe the glue residue dried out due to all your washing? Who knows. Goo Gone it and report back. We're all sure you can figure it out on your own.

Goo Gone is safe for painted surfaces. I wouldn't let it linger any longer than needed however, so we quickly rewashed that area so we'd be able to add a first layer of ceramic.

Well, the issue is if I try to remove the marks but cause more damage, I can’t just take it to the dealer to correct it. However, now, it’s obvious those marks are from the dealer/origin tape and should be covered under warranty. Obviously I can wing it and try stuff, but then the dealer will say too bad you’re the one who decided to fix it yourself. So, if I’m going to try anything I’d like some assurance it’ll work first.

Safe for matte surfaces too?

It's original paint, not an added film...

Right, but using the wrong things can leave it shiny. So just asking.

And you actually trust perfect strangers on an Internet forum like this to "assure" you?...

I'm just looking for solutions man.

Dude, you got THE solution. Goo Gone. Try it. You’ll like it.

It’s like inert, orange peel oil. No prob. Trust me.

Why not take it to the dealership and let them figure this out? lol
Then you'll have the solution and the warranty will be safe

@SoCal949 - if you want more info on what to use on matte paint to remove things like this residue and bugs/tar, just search it. Tons of detailers with advice online. That is where I saw WD-40 and Goo Gone recommended as safe on matte paint. If you don't want to risk it, sure, let the dealer deal with it.

I also use normal rubbing alcohol to remove tree sap on paint, so I would think it would work in this application also. I agree with @Koreanadian, take it to the dealer first and have them deal with it since Kia caused the problem.

I just came here wanting to understand:

1) What it is?
2) Does anyone else have this issue?
3) What should be done to fix it?
4) Hoping to hear I could correct it myself.
5) Otherwise wanted to know what the dealer would do to fix it.

I also was hoping to avoid the dealer because I've had them screw things up before (like put a gash in my steering wheel when they were fixing something else) - not to mention sometimes for these types of issues they won't work on it on the weekends, which means I have to take off of work to bring the car in.

I still don't understand how this just now appeared after 2 months and like at least 6 hand washes. It's perfectly smooth, not tacky at all. I think I'm going to hand wash this spot again and see what happens. If it is still there I guess I'll have to take it in.

As expected, my dealer doesn't deal with this issues on the weekends (and no appointments available in the next 2 weeks), so I have take time off of work to deal with this shit. I wish I knew what to expect them to even do about it, but from this site and others, I don't find a consensus on dealing with the matte paint.
