GMC Sierra, Acadia, Yukon Built Without Ventilated Seat Blower Motors9
The ongoing global microchip shortage has impacted all four of GM’s U.S. brands, including GMC, with vehicle production and feature availability both affected by reduced supplies of these critical components. Now, GM Authority has learned that several GMC models are no longer being built with ventilated seat blower motors as a result of the shortage.
According to GM Authority sources, select units of the 2022 GMC Sierra 1500, 2022 GMC Sierra HD, 2022 GMC Acadia, and 2022 GMC Yukon are now being built without ventilated seat blower motors, starting with April 4th production.
Critically, these select units were already under constraint for ventilated front seats, specifically the feature’s control module. The difference now is that not only are some of these GMC models missing a control module due to the microchip shortage, but they are missing the feature’s blower motor as well.
Both of these elements will be eligible for a retrofit at a later date. Per usual, the window sticker for each affected vehicle will indicate which features are missing that would normally be included.
Look over the table below for a more complete list of the 2022 model-year GMC vehicles affected by feature constraints as a result of the microchip shortage. To note, further feature constraints include the heated steering wheel, heated front seats, heated outboard rear seats, Rear Park Assist, and Front And Rear Park Assist.

GM Authority previously reported on the Buick and Chevy models affected by the latest constraint for the ventilated seat blower motor, so check out the previous GM Authority coverage for more information.
In addition to widespread feature constraints, the microchip shortage has also impacted GM’s available new-vehicle inventory, which, at the moment, is handily outstripped by customer demand. According to one recent report, new-vehicle inventory days’ supply across the auto industry was in the low 30s in March. Going forward, GM is now developing its own family of microcontrollers in an effort to combat the effects of possible future microchip shortages.

We already have to worrie about the junk lifters and the triangle of death makes me not want no gm brands
Any one notice the new Sierra grill looks like Garfield the cat. These re-hashed trucks every year are a mess and even the die hard GM loyalist on here know it too. fangs, bow ties up , bow ties down , remove it , put it back , new shade of black paint , new car dash , door mirrors from the 80’s , or you get the MASSIVE jack looking door mount mirrors on the HD’s. fake Allison , under powered Duramax motor has problems so bad, GM is buying back brand new 2022’s , mary barryass sitting up there bean counting all the while she dangles that carrot about something new that never come’s except for paint colors, and new shade’s of black interior, or they paint the wheels black for the teenagers.
Who cares about seat blowers ? .electric windows locks and air cond is all you need.
No seat blowers? Really not a big deal, unless live in a warm area, and then one might miss them.
Maybe it’s not the best idea to count on Taiwan and communist China to provide such a high percentage of the world’s chips.
The heated seats came with my 2022 CT5. However, the steering wheel heated didn’t. They will install it at a later date. Big deal. Just as long as it comes in before next winter. And besides, the remote starts also warm it up as well.
None of what I just read surprises me at all!!!!!!!!! I bought a used GMC Sierra 2010 5.3 back in 2016 . I’ve only got 123,000 miles on my truck, and even when I had the vehicle a month I had taken it back to the dealership that I bought it and they didn’t replace anything that was wrong all they did was reset the system so the light didn’t show and within 8 to 10 miles the light came back on again, I just didn’t go there once to have the problem fixed . I had gone there 3 times . They only want to take your money and not do anything to fix the problems.
