Does anybody else have this issue? My bumper appears to be separating from the internal clips/support. I noticed this gap yesterday. I am getting so disappointed with this car, that I feel my Honeymoon stage is over. Brakes squealing aready, (have an appointment pending), and now the rear bumper issues. It seems that the car was not put together properly. Hood Automotive lighting Pink Material property Magenta

Yup a lot of us. Go to MustangG.com Shelby 350 and theirs a whole bunch of complaints about this.
That's not good! I don't even what them touching it either. Every time they have done something in the past, I always found small scratches or something around car.
My car is comparable but thats not the worst of it

My hood on the passenger side where the front point of the hood meets the fender is a 1/4 to 1/2 inch higher than the drivers side

Don that should be an easy fix. Just turn the rubber pads up or down to make even. Just be sure the pads are still touching at the bottom (I put a piece of paper under them and close hood and gently pull paper to be sure the rubber stops are making contact)

I might take it to our body shop (i work for a ford store), I took it to them when I got the car but when one of the techs said we could heat this black thing( the carbon fiber support) and get the hood to match .... i waked away.

Carbon fiber doesnt melt ... like plastic

I've go this problem big time on my 2017, even the same color. Placing a floor jack under the rear valance, using a thick rubber pad to protect it, and slight up pressure will push the bumper cover into place, but cannot get the cover tab to clip to the actual hook that is part of the under member assembly that is actually bolted to the body. I did a basic disassembly of the bumper cover form the wheel well around to the tail light, just one 7mm bold and a push pin allows you to snap the cover off the under member. The last two clips near the tail light are not hooked at all, nor can they be. It seems as if the under member is too far in, or something is preventing the tab slot from engaging the actual hook. Same thing on both sides. Something is wrong with either the parts, such that they do not interact together as they should, or perhaps the positioning of the under member? (I don't know what this thing is called, but it is black and has the hooks molded into it. I developed a fix last night adding my own screws in the area hidden by the tail light assembly. The tail light comes out very easy, just three 10mm nuts, but this is a bandage. I may remove the entire rear bumper cover today and see if re-positioning the under member, although I do like my fix, it's simple, effective, and you cannot see it with the tail light in place.

The dealership took mine off and realigned it. It made a little bit of a difference, but it does not look as it did while it was in the showroom. I try not to look at it, unless it starts dropping more.

I think the screws I've added will solve the problem. Not perfect, but much better. Again, I have this problem big time on my 2017 rear bumper cover nearer the tail light assemblies. Placing a floor jack under the rear valance, using a thick rubber pad to protect it, and slight up pressure will push the bumper cover into place, but cannot get the cover tab to clip to the actual hook that is part of the actual mount that is screwed to the body is near impossible. I did a basic disassembly of the bumper cover form the wheel well around to the tail light, just one 7mm bold and a push pin allows you to snap the cover off the under member. The last two clips near the tail light are not hooked at all, nor can they be. It seems as if the mount assembly is too far in, or simply too thick below the hooks, preventing the tab slot from engaging the actual hook. Same thing on both sides. Something is wrong with either the parts, such that they do not interact together as they should, or perhaps the positioning of the actual mount? I don't know what this thing is called, but it is black and has the hooks molded into it, and I am calling it the bumper cover mount. I developed a fix last night adding my own screws in the area hidden by the tail light assembly. The tail light comes out very easy, just three 10mm nuts, but the issue of the tabs not mating to the hooks in the mount drove me crazy and I removed the bumper cover up to the license plate area. Ford needs to take a look at their molds, tolerance stack ups, or assembly process. I had to file down he mount, basically making it thinner in order to get the cover tabs to engage the hooks. I also found that the rear mount was not tightened at the factory, this is the mount immediately below the left tail light.

This knocked down my gap by about 30%.

This is a great answer. Most car manufactures are using glue instead of screws or even welds (cheaper). When these new ‘space age’ glues get stressed (hot, cold, torsional stress) they fail slightly and usually egnored by the average owner. Look at Mustangs in the parking lots, more than half I see have sagging rear bumpers. This fix (screws) would cost in excess of $.05 a car x Mustang Production # = $$$$. :p
Interesting! Thanks for posting the pics mspenc45. If I see the sage get worse on mine, I may get brave enough to do it. It looks simple enough.
mspenc45 are those screws directly behind the tail lights? Is that all that needs to be removed to install them? Thanks and nice work.

Ditto, thanks to mspence45 for the detailed pics...I too am about ready to R&R the rear bumper cover to get it right. I've already had the tail light housing out as well...
This was the first thing I looked for when I picked up my car this month. I had read about it and seen enough cars to expect the "saggy bumper gap". Fortunately, mine was not that bad. But I'm not hopeful that gravity won't win out. Especially after some track time. Right? Oh well, I knew it going in. I'm not going to let it bring me down from my barely 400 miles euphoric high. This car is amazing.

Kid in a candy store. Night before Christmas. Sometimes I just go in the garage and look at it!

Soon as I read these posts I ran out to check mine. So far no problems, and I haven't heard about this with the 2018 models so maybe Ford fixed it. Hopefully. I understand the euphoria. ;-). Great car, enjoy!
Nope I've seen a couple of 18's on the showroom floor that already had it. Even those cars on showroom floor that don't show it usually get it after driving them awhile.

Bummer. Well, I've had mine since Nov. 2017 and no bumper issues, so I guess they don't all have the problem for whatever reason.
Thanks guys for making me look again, after about one year and 3K miles (and a couple track days), mine has started to sag. Damn. Has Ford addressed this with a countermeasure yet?

Yes - I posted on the official Ford Repair. There is a kit from Ford that seems to solve the problem.

Still looks good.
That kit is like a bandaid fix. Some have had it done and it looked better and some it was worse. The TSB doesn't guarantee it will fix it. Theres drilling, screws etc. involved. And pay time Ford is allowed to do kit is not near enough time to do it. So hard to find a dealership that will take time to try to get it right with pay allotted time. Like flipping a coin and hoping for the best. As much as I don't like it I'll just leave mine alone.
