I had a 19 RST, 20 LT 2500 and now 21 GMC elevation and have to say my 21 seems most comfy out of all.....seems like bit more foam in the seat, not a ton but just bit more....definetly feels just bit more refined than my 19, idk if its true just seems that way

How difficult was that?

 

I didn't want the vibration but it was the only way to get the HUD so I ordered it that way ... haven't got it yet tho

You can turn the vibration off in vehicle settings.  

 

Alert Type
This feature sets the type of alert from the driver assistance systems to help avoid crashes.
Touch Beeps or Safety Alert Seat.

 

We had a 2015/6 around here that the vibration devices weren't buried deep enough and became annoying on a long trip. 

 

Not an issue with this '21.

I took out the vibrators. Zip tied them up under the seat. Big improvement 

Did the same. I used double sided tape to mount the sensor motors to the bottom of the seat pan thinking maybe the vibrations would be felt. Nope! So I turned them off.

Bottom line, the seats could and should offer a much higher level of comfort.

Thanks redwngr... Hopefully mine will be buried enough to not bother me

Unless they redesigned the seat bottoms on the ‘21 they are not buried at all. I believe they sit in a recess and the only padding is the upholstery. When I removed mine, I pulled them out through a small hole in bottom of the seat foam. The hole is for the wire and connector to pass through but large enough to remove the sensor motor. I made up two plugs from some closed cell foam and inserted them into the voids.

200  mid thigh. Not bad on short trips but after an hour or so it almost hurts.  Could feel them easily with your thumbs

In a 2016 1500 with them they became bothersome. 

2018 2500 with them they were not an issue.

2021 1500 they are not an issue. 

 

Did have to do a bunch of adjusting and trials to find front and rear seat height to my liking. With that done, I really like these seats.

No longer ever 'notice' them, which imo is the sign they they are as they should be.

Heating on them is way way above that  '11, '15, '16, and '18's. 

 

I'm a fan of these seats so far. 

It was built in October, so it hasn't seen hot weather to evaluate the seat ventilation.

For reference How much do y'all weigh where they are bothering you?

 

225#. Mid to upper posterior thigh.

That’s a great idea. My next mod. I just need to find something to fill the void. Was thinking spray foam and tape over the hole to keep it in till it sets.

We've made several multi day out of state trips in my Sierra and it didn't take long to realize how uncomfortable my seats are. I ended up buying a seat cushion to help: https://www.amazon.com/gp/product/B07MZJGYZ7/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

 

I also found my seat a little hard......old bones i guess

 

This cushion from amazon is very comfortable, makes a world of difference + it's not too thick

might just be me.  And this in a lot of cars from 20 and 21.  They have shrunk the dashes as in they are not as close to you know.  Its kind of a weird feeling.  its like that in my 21 2500,  buddies 21 F150.  So while the seats may suck. I think the dash has a play in making things feel comfortable.

I just got my Denali and drove it 12 hours straight home yesterday.  This is by far the best vehicle seat I have planted my butt in for a road trip.  12 hours with only short stops to empty myself or fill up the truck and I didn’t have any of my usual hip, knee, ankle, or back pain.  This truck is a game changer for me.

Has anyone with the issue had any luck working with the dealer to resolve it?  I am sick after dropping this kind of money, 2021 gmc 2500 Denali duramax with ultimate package, to find the seat almost unbearable after only 1,000 miles. I didn’t notice it on the test drive and the first couple days drove an hour or 2 straight with out issue.  Not sure if they moved or what but it’s driving me nuts. May have to resort to removing them myself. I spent half the 1,000 miles in the passenger seat and it’s extremely comfortable.

    • So, do I go elbow-deep on this thing or list it for sale and play dumb? Seems to "runs good."   I'm about $1200 away from having: -a rebuilt injector ($300) -a new cat ($250) -a new cat back exhaust (OE style) ($300) -a new AC compressor ($200) -AC refrigerant charge ($150)   In theory, this should rectify the obvious detracting issues from its value and operability. Cold AC with a non-squeaking AC pulley both sounds and feels good. An exhaust that isn't cut/hacked in 17 different places and doesn't vibrate on a crossmember would make it sound and feel less janky. A working cat would help the stink, and will save the earth, but *if and only if* the fuel system is working properly, which would also address the intermittent "rich" CEL.   Heard a good one... CEL for "Rich condition" means you haven't spent enough money on the truck lately, and it's letting you know.   Rebuilding the injector would seem to be the most important part. Replacing the cat would be secondary. I don't think mine is plugged or overly restricted, but it might be a little restricted? I have no good way to tell other than seat of the pants feel. I hate the smell.   The current theory is I have a rich idle problem: A bad fuel pressure regulator, or a leaking injector(s) being the highest probabilities. I already replaced the FPR but that doesn't mean its replacement isn't also bad. It was a new part from Dorman, but the packaging looked like it had been sitting on a shelf for 20 years.   This is the (single) upstream O2 sensor shown at idle. I'm getting a lot of "rich" it seems. Sometimes it stays high like that and doesn't drop down. That makes me think it's processing injector leaks or a partially stuck open injector.     Other times it looks like this. Nice oscillations between rich and lean, which is what I think it should be. Under load and at speed, the oscillations are nice and tight and uniform looking, high and low.     Fuel trims suggest the PCM is compensating pretty hard at idle to pull fuel out. But it's not enough to trip a CEL. Something about slowing to a stop: brake vaccum booster, EGR, or the EVAP purge is delayed, or there's pooled fuel in the intake again that's draining into a cylinder is enough to set the CEL. Of course, in two days of driving, it hasn't set. I was hoping to actually look at the freeze-frame data when it sets. IAT is high because it's idling on an 83 degree day here.  
    • Have considered installing a DC to DC charger in your camper to replace your isolator?  
    • Common failure.  You need to replace the fuel door housing.   The painted cover transfers over to the new housing.  To remove the old one there is 4 spots where you poke the plastic to release it.  
    • No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.      
    • Hello from Australia Just sharing that there is now a way to delete the active shutters entirely with just a plug in module. Opens up tons of room to light bars etc.
