Seat Movement Issues

DCazares · May 26, 2016

Just got off the phone with my dealership and the service guy said the technician told him that they are only performing the bulletin on new unsold trucks and that they can order the parts for me to do it but will take 2 months to arrive. They don't know what they are talking about. I'm waiting on a call back from the manager.

My 2016 does it to albeit not as bad. GM installed stops next to the white plastic rotating pieces but there is still a small gap. I will be installing a zip tie to make up the difference. The zip tie will be a wearable part so it may be replaced from time to time.

Had it fixed once on my 2015 and it's doing the same thing again. Will be heading back to get it looked at again,

i have some seat movement on my 2015 dbl cab but mine seems like the back rest part is moving foreword when braking then falling back once stopped is this the movement everyone else is getting? im also getting a popping sound from the same back part of the seat seems to be where the heat element is in the seat.

I think the problem discussed in this thread is that the bottom seat cushion is moving from left to right on turns.

I think I have a slight movement light yours, where the seatback will move ever so slightly foward when stopping, and back after the vehicle stops.

I think GM paid attention....when I was looking at the white clips on the bottom of the seat, I noticed, on my 9/15 truck anyway, metal pieces that are in the same place where other members are clamping next to the clips.

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.

You rock dude! Before my trip today, I adjusted it a bit higher to where I was comfortable, but it wasn't bottomed out like I had it. Son of a gun, the seat felt way firmer, and the rocking vanished! Thank you so much

I took mine back today for the second time. I was promptly told that "there is nothing that we can do" however they changed out some retainers. After about 10 minutes in the vehicle, the seat started to slip again. This is getting old. I called back to the dealership and was told again "there is nothing that we can do". I have called GM and they seem to think that there is something that can be done. Waiting on the dealership to call me back since GM has reached out directly.

Just got it done, didn't notice in short drive home, have to dig up paperwork of what exactly they did. Was in/out in a day.

Well, now I have to dig up the paperwork...the past couple weeks have been getting a squeaking noise every time we make a stop. Tried moving the adjustments around, nothing helps. Took a quick look, does not look like a bunch of new parts underneath, so going to have to do some digging. Definitely still no side to side movement like before when turning.

take it back and have them retighten (torque)the bolts that hold the seat. I had a loose bolt and it squeaked all the time. service manager tightened the bolts to spec and no more noise.

Haven't noticed any, but how high does it have to be to prevent sinking? Edited June 23, 2016 by CadillacLuke24

It is not much actually. Maybe 1/4 to 1/2 inch of the bottom travel.

Sweet! Readjusted it last night, and I think I had it set fine before, but it definitely is now Thanks dude!

I thought that I had fixed my 2014 seat movement issue at around 900 miles. (dealership replaced the seat track) now at 61000 miles it was doing it again and of course it is out of warranty now. Sooooooooooooooo I stopped in and traded for a 2016 1500 Denali on Friday. I got 158 miles and NO seat shifting YET haha. We shall see how it goes.
