Frame Bolts Loosening
This summer we did a 5,000+ miles trip from Ohio out west. After the trip when I was chocking the wheels at my storage site in Ohio I looked up and saw that a bolt holding the upper frame to the base had worked itself free and backed off over 1/2 inch. When I checked the rest of these bolts I found 6 more that were also loose. Is this common? Is this I need to check every few thousand miles? Never occurred to me that the frame might fly off.

If they are coming that loose ? I would try lock washers or red loctite on the nuts /threads .

double nut them . then tighten nuts together when they are snug against each other.

Happened to my 2021 Rogue 25v. I added lock washers and the now stay tight.
At least they have for the 1000 miles since I added them.

Nice picture. I see NO lock washer. Add them. Or change out the nut to a Nyloc version.
Something more for me to look at when dewinterizing;(

With that type of washer there should be some paint scuffing visible if they were tightened down properly at the factory. If the paint isn't scuffed, they were never tight.

I don't see any such "scuffing" in the pic's but that's just looking at a picture.
Loose fasteners are all to common when there are lax QC controls.
At the other end of the spectrum some manufacturers have a system for checking EVERY fastener before the vehicle leaves the factory. On my Titan every fastener under the hood and on the frame has a crayon mark (or paint pen) across the nut/bolt head and onto surrounding metal that shows it was checked. Also shows if it's loosened if witness marks are no longer aligned.
Overkill? Not to me. Going into 17th year of use and not a single rattle.

The stabilizer jacks on my TT did not have any locknuts or lock washers on them. When I brought it home I was crawling around under the TT and noticed it. I put lock washers and nylock nuts on right away. I used a silver metallic sharpie to mark them after hearing about doing it from another forum.

You also can tighten them back up and then center punch the bolt thread right where the nut and bolt meet.

Same problem on mine 8 3/8ths bolts with no bumper washers or washers of any kind holding the entire body box onto the frame! Dangerous and not road worthy. Almost as bad as the 1/8” spot welds holding the torsion axle to my frame.
Has anyone upgraded the bolts? I want to replace as many as possible with 3/4” stainless bolts, bumper washers and lock nuts.
