When I was searching for a replacement truck for my Ford buy back the one stipulation was the truck did not have a moon roof. I see no reason to burden myself with an option that has such a high failure rate and could be expensive to repair.
That's my two cents.

No issues on my 19... then again I've never opened it yet as it's been mostly in the 20s since I got the truck....

Have an 2018 with no issues so far and maybe opened it a dozen times or so, plus it has been raining like crazy last two months with no leaks.

Are you talking about the panoramic roof of just a standard moon roof? I have the standard moon roof and have had no problems. I have read some threads about the panoramic moon roof leaking.

Ordered my 19 with it, It's rained since I've had it,pretty much every/other day. No leaks or issues, But ditto on the sliding cover, close it, No sun.

Have had them on my 15 Sorento, 15 Explorer, 17 Super Duty, and wife's 15 Lincoln MKC. Not one issue. And for the me the novelty has not worn off and would not consider a vehicle without it. Really opens up the interior.

I have it on my 17. I had problems and the track broke (I did a thread on here about that). The dealer replaced the track and despite the track issue I love the panoramic roof and would order again. I don't drive my truck daily and it is parked in a garage so obviously this helps. I really like the amount of light coming in especially since my truck is black on black.

No leaking or sticking here. No issues at all.

My 17 has a pano roof. I love it. I had it for about 2 years before I had problems. It started out by sticking and then popping. Then "crunch"! That was it. It was all kitty wampus and wouldn't close straight. Dealer replaced the whole frame and track system under warranty.

Well, it finally happened. I thought I was one of the lucky ones as I've had my truck since last July, almost 18 months and yesterday my son noticed water dripping off the handle on the passenger side front seat. Don't know if the hose is clogged or somehow disconnected but I put a bucket in the floor overnight and thank god I did. The floor would have been standing in water had the bucket not been there. Time to get in to the shop.

No leaks and no sticking on mine. Had the truck 2 months now and live in SoCal and am out in the desert quite a lot. No sticking issues.... Truck gets washed and detailed every other week and no water leaks noticed either.

'17 Platinum here - purchased in April 2017 - no problem w/ the roof. The truck sits outside when parked and has seen 100s of inches of TEXAS hurricane level rain.
I tinted mine to help keep the heat out a little - for those times I forget to close the sun shade. The ford factory sun shade makes a huge difference in keeping the heat out.

Living in S Tex, there ain't enough tint to put on it that will stop the heat...BUT what does is at Home Depot they carry rolls of reflective bubble insulation. I had some left over from the insulation of the 2 nd floor stairwell and I cut a couple of pieces to fit and slid them in over the shade between it and the glass, works GREAT...

I was in the same boat. Didn't want the moon roof. Ordered a Lariat Ultimate minus that option. For some unknown reason, the truck showed up with a moon roof.
And I actually kind of like it now. Haven't had any issues with it.

I love the extra head room, the light and it sure is a wow factor when getting in the truck. I love it and wouldn't be without it.
