So I am taking my truck into get this fixed and they just called me and said that this is a software issue apparently they have no idea what I'm talking about just say that I go in there speaking with what I'm talking about is ther just clips that are being installed correct

I'm starting to notice the seat movement issue very intermittently. Right now it only happens on one of about 50 hard left turns. It only started acting up in the warmer weather too. I'll just get the dealer to look after it on my next oil change.

 

I've got a few rattles in my truck now too but can't figure out if its my golf clubs in the back seat or the truck haha. I guess there's an easy way to figure that one out.

Yep mine went away in the winter and got worse with the warm weather. The only thing I can figure is the cold makes the parts shrink which tightens things up and the heat makes them expand which loosens them up again. That's the only thing that makes sense for temperature affecting something physically moving like that in my opinion.

This seem consistent with mine. I got the truck in February, and didn't notice this until April. If I max out the front vertical / tilt adjustment, it seems not to do it. Going to take it in and see what they say.

Mine is in the shop right now for this issue. Waiting for an update from the dealer.......

Well got my truck back this morning....so far so good! They installed those retainer clips discussed recently in this thread and greased up a pivot point on the seat whatever that means. So far, solid as a rock. We'll see if this holds up over time.

Update. Had mine fixed nearly two months ago. Knock on wood... solid as a rock. THANK YOU GM! I pray it stays like this. Makes a big difference. :fingersx:

I just wanted to update people on this. I had done the hose clamp in the past and it fixed most of my movement issues, but not all. Also I still had a bad creak to my seat. Even when I wasn't sitting on it, if I would push down with my hand it would creak bad. Today I had some time to pull my seat out and investigate. I put a zip tie around the bolt that's supposed to have a plastic retainer clip on it as per the TSB and that fixed the rest of my movement issues. Then I pulled my upholstery off and removed 4 hex screws from the bottom of the seat that held the two white plastic pieces on. The same two white plastic pieces that we put the hose clamps beside to stop movement. I then lathered the shaft that these plastic pieces sit on with lithium grease as well as in between the plastic pieces and the bottom of the metal bracket that they screw to.

 

I can now safely say I have absolutely no seat movement or creaking. So if anyone is going to fix this issue themselves I suggest they follow the TSB and use the two retaining clips, one for the white plastic piece and the other that goes on the metal bolt as well as grease the white plastic pieces and shaft.

Been a while since back on the forum.

Same seat problem that y'all been describing. I can't stand it anymore!

Took 2014 Z71 to the dealer last Friday and explained the TSB.

Will cost $269.16

Retainer p/n 13405675 $3.33

Shim Clip p/n 13594989 $6.25

Another Retainer p/n 00332364 2@ $ 1.05/pc.

Super Lube p/n 12371287 $5.48

2.2 Labor Hrs.

Extended Warranty will not cover.

I don't believe my ears - how is this not a FMVSS problem? Anything with the word "seatbelt" or "seat" is all just about covered under the Federal Motor Vehicle Safety Standard.

Can one of the GM reps visiting this site PM me? Have seen were the rep contacts dealer??? How does this work?

Just reassured me that extended warranties are a waste of money. Its easy to do yourself and takes less than an hour.

This is happening to my truck too. I bought it in February and it has less than 1200 miles on it. Its very very frustrating! I purchased it about 45 miles north of where i live so I called my in-town dealer to make an appointment. They said they'd cover it. Going in next monday. Hoping for a fix!

Well after about a week of driving it, I'd say the seat is 99% fixed. If I take a hard left turn and really put some weight into the seat in the direction toward the driver door I can feel and hear a very slight pop. Basically it feels like the seat wants to move but the fix ties it down in place really really hard and good.....but it feels "tied down" as opposed to feeling like a solid seat. If that makes sense.

 

Overall, I'm happy as long as it doesn't loosen up and get worse.

Sadly mine has come back after about 2 months of fixing it. It was rock solid when they fixed it so I know it can be done.

gstting weary of all these dealer visits

That's for dam sure!

At $269 total repair

$16 in parts

THATS $125/HR!!! For maybe a high school graduate that passed a couple of certification classes.

I'm not talking about a guy who pulls engines but someone who maybe makes $15/hr...

I'm in the wrong business, wait a minute i am in the OEM parts production business???

    • Question @diyer2 on this line if you please. Are you saying the shudder is the system turning on and off at the frequency of the shudder? Guess I'm asking if you are saying you have seen it do this with the bi-direction scan tool in graph mode? If so have you been able to discern the 'trigger'. Something is telling to cycle rapidly.    My truck just started doing this recently. 197K on the clock. My response has been M5 anything under 55 mph. I treat it like a lugging stick shift. Gear down and let it spin a bit. Engauge M5, then tow mode and then M6 lets the trans stay in 5th but the AFM is active. Smooth like Skippy.    My thought was that as a machine ages the friction gets lower and as the system is load based, the lower friction would allow it to turn on at ever lower rpm until it reaches the lugging point. And yes I am ignorant of any minimum rpm requirement for the system. If you know that would be useful information.    As you know I run a Scan-Gauge II which allows me to watch the On/Off of the signal to the VLOM. While in the shudder mode I'm not seeing is cycle at that frequency or at all for that matter outside the triggers @newdude posted a few years back. Now is it possible that the refresh rate isn't fast enough to catch it? Maybe. It is why I asked my first question about graphing and trigging parameter.     As we have observed from members here the failure point is all over the map miles wise as you note yourself in your opening post. That by itself begs a few questions like fellows that comment on these lifters failing even after the system has been disabled. Long after. 😬   https://www.enginelabs.com/news/tech-tips-replacing-ls-active-fuel-management-lifters-with-melling/   The Gen5 lifters operate the same as the LS versions. In fact they are the same lifter.    https://www.enginelabs.com/tech-stories/sorting-out-gen-v-lt-lifter-failure-with-a-simple-valvetrain-fix/        
    • UPDATE 2: Steering wheel control backlights and control of the cluster can supposedly be achieved by adding a wire to pin 20 of the cluster and tapping it to pin 2 of the main clock spring harness. I'm going to give it a shot - will update  
    • GM Global A pickups 2019-2022 can do OTA programming for the radio.  GM VIP (GM Global B) can do OTAs for almost every module on board.  So a 2022.5 and newer pickup can do OTAs for recalls like the 2.7 fuel flow recall.  EVs get OTAs that improve one pedal driving, radio issues, HVAC issues, updated battery management software, etc.     So age of the vehicle/what GM electrical platform its on will alter what amount of updates can be pushed on OTAs.  
    • Thank You.   So far my new ride is making me look like a genius for going with the 3.0L, as my first fuel refill occurred over three weeks from when I took delivery.  This engine combination is very amazing.  So far no issues and had not done a regen yet.
    • I am curious as to how much fluid you put back in the transmission ( assuming you had replaced the filter to compare to my findings ) and then went through the process of warming up the trans before pulling the check plug to drain out the excess and if you measured how much came back out.    I just found it surprising that some claimed a certain amount less fluid being put in and then draining some back out. The attitude of the truck as per if the surface is level and how the trucks stance is would make quite a difference since the check plug is right at the front of the transmission.
