2022 GMC Sierra HD Heated Seat Retrofits Under Way

Customers affected by a recent constraint on heated seats for the 2022 GMC Sierra HD are now eligible to have the feature retrofitted under a new GM customer satisfaction program, GM Authority has learned.

For those readers who may have missed it, certain 2022 GMC Sierra HD models were placed under constraint for the Heated Front Seats feature last year, with GMC Sierra HD SLE, SLT, and AT4 trim levels all affected. The 2022 GMC Sierra HD was one of several GM models affected by constraints for the heated seats feature as a result of the global microchip shortage.

The constraint was lifted for the 2022 GMC Sierra HD in May of 2022. Heated front seats are normally offered as optional for SLE trim levels, and included as standard for SLT, AT4, and Denali trim levels. The comfort feature is not available for the base Pro trim level. To note, the 2022 GMC Sierra HD Denali was unaffected by the heated front seats constraint.

Now, according to sources familiar with the matter, 2022 GMC Sierra HD owners affected by the heated front seats constraint are eligible for a free feature retrofit. Dealers are currently contacting owners to inform them as much, while dealer technicians are instructed to install the missing components and update the vehicle’s body control module.

It’s also worth noting that the 2022 GMC Sierra HD was also hit by a constraint for the heated outboard rear seats feature and ventilated seats feature, both of which will be addressed in separate GM customer satisfaction programs.

The 2022 GMC Sierra HD is the third model year for the fourth-generation heavy-duty pickup, offering two engine options, including the naturally aspirated 6.6L V8 L8T gasoline engine, rated at 401 horsepower and 464 pound-feet of torque, and the 6.6L V8 L5P turbodiesel Duramax engine, rated at 445 horsepower and 910 pound-feet of torque. Under the skin is a more-capable variant of the GM T1 platform, while production takes place at the GM Flint plant in Michigan.

  1. Great news!!!! Oh I still don’t have my 2022 SLT!?! Only ordered Jan 2022. NICE! Status from GM 800#. MP

  2. Well started and underway may differ in reality. I contacted GM today and inquired on and was told that and I quote:
    ” I can confirm that GM has developed a retrofit process for the heated steering wheel and seats in your 2022 GMC Sierra. We have begun the retrofit process of installing semiconductors in late Q2 2022. We understand that due to the scale of the number of vehicles impacted, this process may take some time to complete for all of the vehicles that require retrofit. Once parts become available, you will be notified by mail so you can return to the dealer to receive the retrofit.No further information is available at this time as we are unable to provide an eta due to the amount of vehicles affected. We are working to have all vehicles completed as soon as possible and once parts are available you will be notified via mail.”

    I would not get any more excited about this statement than all the previous broken promises made regarding this issue, just saying ;-(

    1. I find the terms GM uses comical. Install semi conductors. It’s just a little module you plug in. Shows how qualified the head set Harry’s are on the phone. As long as the switches are there most it takes is a couple minutes. Seat heat modules are under the seat on most I think.

  3. Imagine That. Still waiting for my “letter in the mail”.. DEAR JOHN. also how nice of GM to not charge me for the options I bought and paid for but never recieved. How magnamomis of them.

  4. Finally….. Received my 2022 2500HD AT4 1/15/22 just 8 weeks after I ordered it since I didn’t add all the navigation and safety stuff, which would’ve delayed delivery. Two friends ordered the same truck at the same time but with all the bells and whistles and they are still waiting for delivery. For me, it’s been 9 months, 1 week, 2 days until announcement came that the front heated seats will be retrofit. Not sure timing from announcement to actual install. Bet my wife dinner it will be within 4 weeks.

    In this article it talks about the rear outboard seats being heated. GMC dropped that option for 2022 in the 2500HD line, and after review with my dealer at a service appt, the rear outboard seats can’t be retrofit. There are no switches or heaters installed from the factory. I knew that when I bought the truck. Sadly, 2022 will be a basturd year w/o rear heated seats in the 2500HD AT4 out of the 5 year model run. As I understand, the Denali level has rear heated seats, but I could not justify another $7k for a Denali. Wish I did, but,,, would still be waiting for delivery…

    Still no word on ventilated seat retrofits. And same for heated steering wheel. Sure hope to see rest of retrofits before next model year comes out…..

  5. I don’t understand what you are saying, I have a 2022 2500 HD AT4 with heated seats that I got in November of 2021. Are you changing something on the heated seats?

    Reply
    1. You are not included in the retrofit; I bought a 22 AT4 in Feb 22 which came without functional heated seats and heated steering wheel. GM promised to have them retrofitted by end of Q2 2022…still waiting

      1. I have the same truck, waiting for heated seats but came with heated steering wheel

  6. I received my 2022 SLT in April 22, it was ordered in Dec 21. I’m very thankful it came in missing just the heated wheel. If anyone comes out of the missing heated seat/wheel/ventilated seats with a completely working system please post back here.

    GM ‘saying’ the heated seats retrofit is underway… as yet it looks that none have actually been installed.

    Reply
    1. GM said during my chat inquiry that they could not say how many units were affected, how many had been done or in what order the notices were being sent out. When I asked about position in the retrofit queue was by Vin, purchase date or manufacture date. The person just kept saying it was due to circumstances beyond their control so they could not provide any additional information.

      If they have no control over the circumstance than how could they start, how could they release the statement that the program was begins, I suspect another hollow promise/commitment regarding this program to install and make functional a feature(s) already paid for 10 months ago by me.

  7. All good questions I’ve been asking too on timing, which vehicles, in what order. Total lack of communication and organization. If I did my job this way….. :-(.

    But feels like they all suck. My uncles 2020 F350 diesel plugged particulate filter at 65k. Indianapolis Ford said warranty up at 60k, too bad. $6k repair bill. He sold it and bought a GMC 3500.

    Toyota is looking better every day, but they don’t have a 2500 or 3500.

    1. That brings up another discussion point on the retrofit.

      If the retrofit chip fails at or shortly after install what happens ? I go back to the bottom of the list ? What list the one no one at GM who will actually interact with a owner knows about.

  8. I’m still waiting on three computers for my 2022 Duramax AT4. I hit up customer service today to check on status, of course they didn’t have one. However, I did confirm that they are letting customers know using their recall system. i.e. you will get something in the mail. This wasn’t good enough for me though so I worked a little magic in AWS today to monitor the website that reports recall status by VIN. Now, when my recall status changes, I will get an from email from the service I set up to let me know computers are available. It sure would be nice if GM did something similar for their customers.

    1. jeffj803, what is the AWS system you are referencing here? Thanks in advance! -Gerry

      1. Gemassie,
        I have a synthetics canary configured to check the recall page for my vin and look for this specific text “Currently, there are no recalls or programs associated with your 2022 GMC Sierra HD Crew Denali/AT4-T1”.

        If it doesn’t find that text, i.e. the text has changed, it will send me an email.

        1. Quite the customization! Is that a GM website or other source. Can you share the link? Thanks again.

          I just got a note from my dealer, he checked my VIN and said nothing is showing for a retro fit yet, and they’ve had no one showing up to claim one. This is a Rick Hendrick dealer and I trust them.

          1. Sure thing, it is GM’s website, just add your vin after the equal sign
            https://experience.gm.com/ownercenter/recalls?vin=

            It is a shame that GM hasn’t thought to give users the ability to get recall status updates via email…

    2. Well, my number came up for heated and ventilated front seats, just in time for the cold weather. I reached out to my dealer, they got the computer a day later, install and programming took about an hour.

      Reply
      1. Jeff, did you get the vented front seats too, if that option is in your truck? The recall I have says they will do both at the same time.

        Reply
        1. Yes, heated and ventilated front seats are now fully functional.

  9. I purchased my 2022 Sierra 3500 AT4 in June 2022 and I’m still waiting for the retrofits for the 1.) heated steering wheel, 2) heated/ventilated front seats and 3.) Front and Rear park assist. I called and talked to the customer care rep about this and she had no clue about anything, so I asked her why it is that the new 2023 trucks are coming with these options working but their not fixing all the owed retrofits. Needless to say she just clammed up!! This is the first time since 1992 I’ve owned a GM product I guess I will be going back to Ford again….

  10. Gm is basically just flipping us off. Paid for a feature waited for 10 months to have retrofitted and albthey can say is we understand your frustration but it is caused by circumstances beyond our control.

    I guess the focus is on getting more customers on the line to disappoint and deceive.

  11. End of the month so I called my dealer again like they asked me to do at the end of every month. Have been doing this ever since January. Once again was told not going to be this month for a heated seat retrofit, maybe next month. Although this time he said could be January or February, so it definitely sounded like not going to happen before the end of the year. That’s just for the heated seats. Absolutely no clue whatsoever about the ventilated seats and the heated steering wheel. Unbelievable how poorly GM is handling this. How can GM continue to push back existing customers when every day there are more new vehicles on the lots that have all the parts?

    1. Not at all unbelievable ! After 8 months waiting and no ACTUAL information from gm or the dealer is is now the standard response each month to say “ we realize your frustration but it is a circumstance beyond our control”. Which now does not even make sense since new trucks are being sold with the features I paid for in Feb/22 and am still waiting to receive.

      GM is looking more and more dishonest and unconcerned about tier reputation with each passing week.

  12. Just wondering if anyone else has had my experience. I received my 22 gmc at4 2500 July of 22. My heated and ventilated front seats and rear heated seats did not work. (Waiting on a chip). After about 2 months the rear heated seats started working all on its own and still works to this day. About a month after that my front heat and cool started working on its own but stopped working again about 3 weeks later. I have not taken this truck back to dealer or had any mods since purchase.

  14. So finally scheduled the heated seat retrofit. Hopefully the parts will arrived in 8-10 days at the dealer as promised by GM.

    But in typical GM fashion so far no letter was received in the mail I discovered by getting an oil change and being asked by the service advisor if I wanted the parts order and an appt to scheduled.

    Issued and parts I assume released on Sept 16 no notice given Sept/Oct/Nov or Dec until teh service advisor at my dealer notified me that it was incomplete and available.

    When I went looking I found this on the MYGMC App

  15. So now it’s another month later. After getting frustrated with endless excuses from GMC dealer I purchased truck from I took the GM recall info and went to the local Chevrolet dealer and asked him to order the part for the heated seats. He said sure no problem they should be in within a week. Two weeks later I called and left a voicemail and no response. So at the end of the third week I called again. Parts guy said there are two chips and only one of them came in and the other one is back ordered. He estimated a month. And he could not tell me if I was getting heated and vented or just heated seat retrofits. I also asked if there was any update on the heated steering wheel retrofits. He did not know any asked his coworker and he said they don’t have any updates either. I can’t believe after a full year of ownership this is where things are at. And I can’t believe Tia has left their dealers in the dark for a full year. Did a quick search on Google and made a rough estimate that GM produced 2 million vehicles in the year 2022. Seems like most everything they produced was missing at least one part. Making assumptions here but trying to estimate how big of a problem GM really has, and how long it’s going to take to resolve. I received my 2500 HD on January 15th 2022. Can’t tell if GM is going in order by delivery but if that’s the case and I’ve waited a full year with no retrofits, then there are a lot of people behind me who are still in for a very long wait

  16. Can you tell me when I will get my heated seat and steering wheel operational? I picked up my GMC 2500HD SLT February 2022 and here it is January 2023 without one letter from GMC or the dealer that they are working on this. I was promised by spring of 2022 when i purchased the truck. Why can’t the deal put in my VIN # and even acknowledge that my truck is on the list let along a date of repair. Customer satisfaction with GMC is at a zero because of leadership of GMC not the product.
