When reading my owner's manual it clearly said that the seats only come on at a low setting when remote started (and it has to be enabled from the settings menu). Like somebody else said, the top of the leather is probably still cold, but the internals are heating up for when you get in and turn them on. I'd do a comparison to the rear seats to see which are colder.

I got in touch with a GM insider and got this information back today. We are all screwed if we want the heated and cooled perforated seats to be warmed on remote start. NOT GOING TO HAPPEN with the new design. I tried a bath towel earlier just stuffed it under the head rest and let it lay on the seat back and bottom while I let it run in remote start. Slight improvement with remote start the seat surface felt slightly warm. Going to go check out the Fords this weekend and see how they have theirs setup. Might be industry wide problem if they are using the same supplier. However if Ford has it figured better then I think we should challenge GM to step up to the plate and make an improvement.

 

I am in research so I talked with some of the engineers who designed this, and here is the short of it:

 

· There is a difference between heated seats and ventilated heated seats, whereas the heated only seats have a tighter grid (they have no ventilation holes) so they are more effective. This is the main issue, as you need air paths where the heater grid cannot be for the ventilation, which are present for the heated seat option only.

 

Other things to note:

 

· During a remote start, power is going to the heated seat if the DIC option is selected and the ambient is below 10C.

 

· The seat controls to a grid temperature. It feels cold to the touch during a remote start as the foam above the grid is not compressed and little heat reaches the leather. But if you sat in the seat during a remote start (I know, that is dumb), then you would know the seat heater is working.

 

· The dash light does not come during on during remote start, and once you press the engine start button to drive off, you also need to press the seat heat button. The default running condition is off, even if the default remote start condition is heat on.

 

· I suppose if you put a 10 inch by 2 inch foam block in the seat, then set a full 5 gallon water jug on the foam, that the seat would then be warm. The foam would stop the heat transfer to the air and the foam would be compressed to allow the heat to reach the leather.

 

· Certainly the use of the configurable DIC option of Heat on during remote start (this is the factory default) is helpful, it is just that it is not able to feel warm right as you sit down

Good info. I traded a 2012 F-150 Platinum (it had heated and cooled seats) for my Sierra - so I can attest to the heated seats in it. They were significantly better than my Sierra's seats. In the F-150, you could tell that they were on and had felt like they had been on at the highest setting during remote start, unlike the GM where you wonder if they're really on. So it is possible.

 

I still like my Sierra better than the F-150 though!

dont have the time to read the above, but the remote start with heated seats doesn't work

 

the only people who think it works are gm apologists who live in a warm(er) climate than those of us in the cold zone where we know the f'n heated seats dont f'n work with remote start

Eh... really? Not very constructive. I hope that was an image of the pill you took after stating that anyone trying to have a constructive conversation about the topic is an "apologist." Maybe take the time to read the information before posting snarky comments about the information you didn't bother to read? :dunno:

That makes a lot of sense to me. I remote started about 8 minutes before leaving this morning and was paying close attention to the seats; again, the seats were definitely cold, but they weren't as cold as they usually are when I *don't* remote start, and within ~30 seconds of sitting down (after starting the truck and flipping on the heated seats) I started to feel warmth - which is a lot faster than I normally do when I don't remote start & turn on the heated seats. That can take 2-3 minutes before I can feel any discernable heat. (I don't have cooled seats, only heated.)

 

This is personally my first vehicle with heated seats, and *my* first GM vehicle (we bought my wife a Traverse earlier last year, and I had my dad's Avalanche for a few months after he passed away) so I can't compare it to anything else. If past models were able to fully heat the seats in remote start mode, I'm not sure why these wouldn't too. It'd be nice to get in and sit down into warmth.

Jeez Loueez too bad you have trouble reading but do not be ashamed there are a lot of people in the US that do not read very well. I tend to agree that it does not work very well in remote start at all but I think you will find that the seats are ON they just will not heat unless your arse is in there LOL. Piss Poor design from GM on this. I stopped by the Ford lot on the way home and had the sales dude fire up a 2014 Lariat with heated and cooled seats, they were nice and warm and toasty in about 5 minutes WITHOUT anyone sitting in them. Kinda like what I expected from my 2014 GMC Sierra SLT Z71 4x4 and those Fords are kinda cute I might have to look at those a bit closer.

The newsletter you posted a link to has been posted in another thread. However it's wrong. It states the seats will come on at the highest setting when remote started. That's just not the case with what people are seeing here. Unless the info stated is for trucks being built after a certain date.

For grins I decided to checkout some Cadallac and Buick forums to see if this is an issue with these luxury cars. And to my amazement there are complaints there as well. Sounds like they were reading our GMC mail. Its disappointing enough to have this with my $51K truck, but how would you like to be one of those that bought a $70K plus luxuray vehicle and have this issue. Looks like GM has this remote start/heated seats dilema across their lineup. And they were also complaining that the steering wheel does not heat during remote start. Heard that before. Man-o-man, somebody at GM didn't think this through very well :(

It will be interesting to see how well the cooled seat feature works in remote start, if we ever get some summer warmth so we can test it. These dang sunspots are way down and we are going into a new ice age we are going to NEED these heated seats to function properly come on GM SAVE us. .

Yes that is correct the heated steering wheel does NOT come on in remote start. BooHoo YES HORRIBLE what is the world coming to?

Pink Floyd another brick in the wall - "How can you have any pudding if you don't eat your meat" also misheard repeatedly as "How can you have any pudding if you can't see your feet" I kinda like this Bose radio system although some have said it is not very good. I guess it is all from perspective since I have never been into the tunes and fancy audio equipment scene. Got my new BedRug installed yesterday I love it. Pics attached .

Well, I'll have to join the club. Mine don't heat during remote start, either. Doesn't get cold enough in East Texas to really use that feature, though, so I never noticed, but we have had temperatures in the 20s. But, in the meantime, from the manual:

 

Remote Vehicle Start

..........

If the vehicle has heated seats, the

heated seats will turn on during

colder outside temperatures and will

shut off when the key is turned to

ON/RUN....

      Fred was in the fertilized egg business. He had several hundred young pullets, and ten roosters to fertilize the eggs He kept records, and any rooster not performing went into the soup pot and was replaced. This took a lot of time, so he bought some tiny bells and attached them to his roosters. Each bell had a different tone, so he could tell from a distance, which rooster was performing. Now, he could sit on the porch and fill out an efficiency report by just listening to the bells. Fred's favourite rooster, old Butch, was a very fine specimen, but this morning he noticed old Butch's bell hadn't rung at all! When he went to investigate, he saw the other roosters were busy chasing pullets, bells-a-ringing, but the pullets, hearing the roosters coming, would run for cover. To Fred's amazement, old Butch had his bell in his beak, so it couldn't ring. He'd sneak up on a pullet, do his job and walk on to the next one. Fred was so proud of old Butch, he entered him in the City Show and he became an overnight sensation among the judges. The result was the judges not only awarded old Butch the "No Bell Piece Prize," but they also awarded him the "Pulletsurprise" as well. Clearly old Butch was a politician in the making. Who else but a politician could figure out how to win two of the most coveted awards on our planet by being the best at sneaking up on the unsuspecting populace and screwing them when they weren't paying attention. Vote carefully in the next election, you can't always hear the bells.

      High Country Suburban build confirmation

      By 3CarSeatDad · Posted

      Can someone confirm if the GM order workbench terminal is able to validate a custom build sequence:   1) Initialize the Allocation Base: Open a new vehicle build queue, select the 2026 Chevrolet Suburban 4WD, and pick the High Country (3LZ Preferred Equipment Group).   2) Select the Diesel Powertrain: Go directly to the engine configuration screen and choose RPO code LZ0 (3.0L Duramax Turbo-Diesel). Ensure it maps to the MHS 10-speed automatic transmission.   3) Deploy the Seating Swap: Navigate to the Interior Options screen and enter RPO code ATT to replace the standard captain's chairs with the power-release 60/40 bench seat. Because you are not trying to force a separate luxury or air-suspension bundle, the standard, premium D07 Fixed Floor Console remains active. The system will accept this change immediately without triggering a warning message.   3)Apply Heavy-Duty Hauling Capability: Input RPO code NHT (Max Trailering Package). The commercial terminal will automatically bundle the required trailering hardware and software modules to support the diesel engine's maximum towing capacity.   5) Layer the Premium Tech and Glass: Separately add code C3U (Panoramic Power Sunroof) and code UKL (Super Cruise) to the order screen.   6) Run the Final Validation: Click the "Validate Order" button at the bottom of the interface.

      Looking at ordering a '26 WT because I want a std cab, std bed

      Spent the last hour or 2 googling and reading up on the spacer thing. I don't like the loss of thread contact on the slip on spacers, but it appears you can get "extended" lug nuts that reach into the hole of the wheel to get back the lost threads. Looks like the only true hubcentric slip on spacers are at least .375". I'd want as little as I could get away with and don't want to cause other clearance issues going any thicker. Bora seems to offer what appears to be a well made .375" spacer and extended lug nuts. I searched here and did find a couple threads recommending Bora. But not cheap. By the time I buy spacers and lugs, new TPMS sensors, then pay a tire shop to install the new sensors, I suspect I'm going to be in over $400. Thinking about running out and getting some washers to put behind the wheel to see if .375" is enough to clear calipers, turn lock to lock without rubbing, and to see if the wheels/tires look strange pushed out a little. This would just be to check fitment.

      Road Master Active Suspension

      By Core-Lokt · Posted

      Roadmaster makes some quality parts; I have their sway bar. I considered the RAS, but I ended up bagging. I didn't know what kind of ride I'd get with RAS, and the bags have interior jounce bumpers, so I can run 0 pounds pressure. I figured I'd have the best of normal suspension ride with assist on-demand. But it seems you got pretty much the same in one item.
