2023 GMC YUKON Seats Problems

After GMC completed 4 recalls recently, my drivers side seat lumbar support started automatically inflating to the highest setting, as well as the shoulder support. I could not deflate the shoulder support at all, but could deflate the lumbar support, but had to do it every single time I got in the vehicle. After they did additional recalls about 30 days later, the issue got worse and often times I'm unable to deflate the lumbar support at all, making driving extremely uncomfortable and what I would deem slightly unsafe given how inflated the seat is. The fact that the 2nd set of recalls made this situation worse makes me suspect it's related to module updates as opposed to my particular seat. Now I am on the hook for a $1200 fix. 2 different GMC locations did the recalls.....I do not blame either of them, I believe this is a defect...

The headrest in the 2nd and 3rd rows of the 2023 GMC Yukon are not adjustable or removable, reference page 39 of an owners manual. This is a major problem when installing car seats into the vehicle. Because of the design, the headrest tilt forward and do not allow car seats to properly sit against the back of the seats. This causes a gap between the back of the car seats and the seat back of the car. I have 4 kids and 3 different types of car seats. All of the car seat manuals say that for proper installation the car seats must seat flush with the seat back of the car. Well this cannot happen because of the design of the vehicle. Therefore I cannot properly install car seats of any type into this vehicle. I am not the only consumer with this issue as it is all...
