loose rear-seat latches
 

Hello everyone.
I have taken in my frs several times for the repair of the noise coming from the rear. They determined that it was my rear seat latches coming a bit loose after driving. Their solution was have me slam my rear seats closed to fully engage the locks on either side. This solves the problem, but only temporarily. Once I go over bumps it has to be redone.

Anyone else have this issue?
Thoughts?

I believe I have the same issue... I've got some felt pads that were purchased for the bottom of our furniture. I intend to stick some of those so to keep the seat latched tighter and see if that remedies this problem.

I THINK I have this problem. I'm not sure whether or not it is the "rear deck popping" sound or the seat latches. I would definitely try wrapping the latches with a foam substance if it is making sounds though.

Mine makes the noise too when the body flexes. The noise goes away when I spray WD40, but it lasts only for a month. I tried white lithium grease also and that lasts only a month too. My next step is to put some padding there. I'm planning to try it this Wednesday.

Thanks for the replies everyone! please let me know if those fixes work for you!

Padding didn't work.
I wiped off the grease I applied before and put some blue painter's tape as padding.
It still made the noise. :(
When I fold the rear seat down, there is no noise.

I don't know what else to try.

How about Sugru or Plastidip? The extra width on the connecting ring may be all thats needed to shut that noise up.

I have a feeling that making the connecting ring thicker doesn't remove the noise. I put 3-4 layers of tape around them so that I had a hard time putting the rear seats locked. I'm thinking it needs to be able to slide instead, and that's why greasing works. Maybe I'll just keep greasing and it might stop making the noise someday.

Must be the locking mechanism being a little to loose to not rattle over bumps.. Ugh.. Always the stuff thats buried inside the seat or dash panel, lol.. Already dynamatted the deck and side pillar rattle prone areas..

if your seat is coming undone it may not be fully locked. push the circular buttons at both sides down completely :iono:

Wow I completely forgot about these buttons. Thanks lol.

OP thanks for posting this. I fixed a pesky rattle just by re-closing the seat back.

close but no cigar
 

This is the same story that Toyota techs told me. "oh you are just not closing it well enough to engage the lock fully" well I am, and I have to slam it to lock all the way. But even then, just a little driving over some slight gravel or bumps and the seat lock disengages slightly to make that rattle.

:brokenheart:

I went in the back seat and started pushing down on both side's buttons to lock, and i noticed that the passenger one seems "bouncy". In other words, when you push it down and tap the seat a few times, the button will pop back up and unlock itself; whereas the driver's side wont.

Anyone else have a similar experience

Mine was rattling, but mine came from the plastic covers over the child safety latches on the rear deck. I put some shelf-liner between the cover and the plastic piece it snaps into and the rattle is gone.

interesting find!
 

Im gonna have to check this out and see if mine is rattling there.
Still need to fix the latch issue though.

I this this issue too. But i found this out after they put padding on my left and ride airbags :(

1. Lithium Greese/WD-40 only works for a short time
2. Only solution: Closing the latch hard

Did you try using some electrical tape?

Lithium Greese/WD-40 works for only 2-4 weeks for me too. WD-40 seems to work longer.

I've never tried closing the latch hard. Does it work until you fold down the seats again? If so, then I'll try that the next time. I applied WD-40 this week, so it will be 3 weeks or so until I can try it.

I tried blue painters tape around the hook to make them thicker. It actually made it worse.

I just checked mine and slamming them shut worked but i discovered the handles from the trunk access are extremely sensitive and you have to close them from inside the backseat when i tried to close it from the trunk the right latch wouldn't latch.

also.
 

when you slam the back seats, the fix only lasts a short while (at least for me). after you drive for a bit and go over some uneven pavement or cracks, the vibration will cause the issue to reoccur.

anyone else experience that?

I found in another forum about the rattle/vibration noise from the rear seat latch.
His one was caused by the black plastic piece touching the silver piece. (If you can tell what I mean from the above picture.) He got rid of the noise by applying some grease in between the 2 pieces.

This is not the case for me because mine is a popping noise and not rattle/vibration noise. But if anyone here is interested, it might work.

I had this problem in my WRX. I wrapped the bar that connects the seat to the latch with electrical tape and it got rid of the rattle.

I sprayed all around but I haven't sprayed into that area specifically, I'll have to try.

Yup same here but I find that's the quickest fix

I think your trick might be a good fix, I'll try that out. Thanks!

I tried using Vasline it's been over 3 weeks and no noise. I'll update if there's any change.

Thanks for the bump. I'll try it out.

i noticed my latchers werent lining up the same on the metal bars the latch too. on the side that was affected, i folded down the seat, pealed back the carpet down by the hinge point, loosened the single bolt on top, pulled that corner of the seat as far forward as possible, and snugged it back down. the seat now shuts more solid, and the rattle/pop is gone. ill take a picture of the mentioned hinge later, i forgot to do it earlier.

Sweet please do!

for me it was the left side, the metal bar was sliding into the latch to high, so when the hook of the latch would close, it had play room, so that side of the seat needed to come up, so with the seat folded down, i pulled it towards me. you can get at these hinges by just un fastening the bottom of the carpet and pulling it over, its one bolt, 12mm. make sure you pull quite hard while tightening the bolt back down, as the torque wiil try to twist the hinge out of place. hopefull this works for other people too cause that was driving me crazy!

I have the same problem. Rattling/popping in the rear. It would go away temporarily when slamming the rear seatback shut. It's not the rear deck since I already "cracked" the welds open and sprayed lithium grease.

So far it's been about a month the Vaseline does the trick

Thanks for the info! I just did this fix and it worked for me. Drove the car 100 miles today, the popping noise hasn't returned. Mine also turned out to be the driver side hinge. Easiest fix so far. Anyone with a popping/rattling rear deck should try this fix first.

Resurrecting an old post...I know this is an old thread, but the rear seat rattle just reared its ugly head a month ago at around 11,500 miles on my 2015 FR-S (now with 12,500 miles).

Initially, I thought this was a suspension noise since it seemed worst when the car twisted a bit over asymmetric road bumps. I had jacked up the car and checked everything underneath (on the odd chance it was a loose sway bar bushing). Nothing was loose and the heat shield above the muffler was not hitting anything. I then checked the trunk. I removed everything (tire, foam, tools, plastic retainers, and rear seat back) and reinstalled and tightened all. After this, I pretty well isolated this to the rear seat latches. I messed with the rear seat latches, slamming the seat, then pushing the seat top buttons down to insure it was well latched. It seemed to get better, then came back with a vengeance a couple of days later. Today, after reading this thread, I unbolted the rear seat hinges and pulled the seat back towards me. I greased (using Phil Wood bicycle grease) and sprayed the seat latches with some Lithium WD-40. I also sprayed the package tray seams on the off chance it was the rear tray "pop". In any case, a test ride that rattled like crazy yesterday was repeated today. It seems to have been resolved.

Old thread but relevant. I was also having the single pop noise coming from the rear seat latch. I loosed and adjusted the bracket as discussed above and lubed the workings of the latch with vaseline and it has so far eliminated the noise. Thank you, it was driving me crazy!
