Seat Movement Issues

[RBSilvy85]

I just wanted to post that the hose clamp fix worked for me too, and my seat had some pretty good movement in it before it. Very surprised it was such a simple fix!

If you are running with the seat all the way down then it will rock front to back. I found this on mine after the really tall service tech drove it and 4 trips trying to get them to fix it. It will also sink if not raised far enough. The problem is in the 4 link seat suspension, if it is too low the links do not have the mechanical advantage to keep the seat from rocking back and forth.

 

 

Does this issue only affect manual seats or does it apply to the 10-way adjustable, too? Just curious.

I believe it only affects the power seat option. Mine is power, not sure if it is 8 or 10-way though.

I just his clamped mine and said f it

Do you have a picture so I can see where you are clamping it? I have the same issue.

 

I also just clamped my 2016 (Ya my 2016 still had the seat shifting and clunk issue) and it worked like a champ! No more shift, the seat stays in place when making a turn. #JUSTCLAMPIT

Do you have a picture of where you clamped it? I am having the same issue.

I'll make it easy for you. But it is pretty much mentioned about every 3rd page.

I broke down after dealing with the movement for the last 8-10 months and had the dealer check it out today. Started doing a lot of squeaking here the last week or two along with more noticeable movement side to side and front to back and I was fed up. They said they had to order a new frame and it will be in sometime tomorrow. Not sure how long this fix will hold up as I have fallen way behind on reading this thread; and don't know of anyone else has went this route. I imagine if it uses the same parts everyone is replacing with the hose clamps, then not long.

Awesome work here guys! I've been trying for the last month figuring out what was moving in my seat. Came across this thread. Didn't believe this was going to fix it...but it seems to have! My dealer thought I was going crazy and why would this be that big of a deal. I told them this $53,000 brand new truck felt like sh!t driving it (also the tranny is really annoying as well). Many thanks guys for figuring this out!

Most Dealer service "ADVISORS" are pretty well trained to try to deflect any warranty claims. I had the seat track replaced on my 2014 at around 5000 miles due to seat movement issues. It started doing it again at around 61000 miles and 2.5 years later and I traded it in for 2016 Denali 6.2 problem solved "SO FAR"

I have purchased a 2016 Sierra SLT and only had for a month and a few weeks ago i have started experiencing this exact movement clunk sound when turning corners. Anybody have any luck with the dealerships solving this issue?

 

I have not brought the truck in yet but would like to arm myself with some information before I go. I know how much the dealership is unwilling to admit when there is an issue.

 

Very disappointing considering the price of these vehicles and the fact this issue is still happening.

 

I am in Canada but that shouldn't make a difference.

If you'd read this thread, the cheapest, easiest fix that works is the hose clamp fix. You don't need the rubber underneath the clamp though. Many have insisted in going back to the dealer with the problem only returning. The clamp fix is the permanent solution. Save yourself time, headache and aggravation from the dealer.

Well I am gonna see at least what the dealer says. I also have a friend who is a GM mechanic and going to get some inside info on any bulletins issued.

To each his own. This is what I'm trying to tell you. The TSB they have for the seat doesn't last. They practically take your seat apart and some who have had it done say it became worse after the dealer fixed it. This thread has the TSB listed. Just trying to help bud and save you hassle. You can fix it for $2 and it will never move again. But if you feel you need to go to the dealer then get you some ​

I really only noticed seat cover movement and had that worked on under warranty. Said they secured it and had the seat cover move on the way home from dealership. They ended up replacing seat bottom cover. It does not seem to move as badly as original so far, but it does move. Anybody come up with a fix for that? I have looked at how it is mounted and really not much holding it from sliding out of place. Whole seat started moving, as others have described on here, only after seat cover was replaced. Going to try hose clamp fix.

I wanted to add a bit of info here. If I had a do over I would have tried the clamp fix and most likely lived happily ever after and maybe still been driving my 2014 SLT. However I decided to MAKE them fix it and right after they FIXED it with a new seat track the bottom seat heater quit working. Then the side of the leather on the bottom came lose at the threads (most likely from them messing with it) and they replaced that and then the seat cooling became intermittent AND THE BOTTOM HEATING WENT OUT AGAIN. Out of warranty of course so my suggestion is to try this simple fix before you allow the dealership monkeys to mess your truck up. Why take the chance on the monkey boys screwing other things up PUT THE CLAMPS ON MAN
