Replacement Front seat Caution Pretensioner

We purchased a used 2019 GC with very low millage but it only had manual seats. So we decided we would look around and try to come up with at least an Electric driver seat. As it turned out, according to the salvage yard info, i needed to stick to the 2019/20 year model. We eventually found leather front seats, electric driver but manual passenger, but we wanted a matching pair and the shipping was the same for one or two so we bought them both. I must say I have learned a lot about the topic of front seats and Salvage yards. First of all most automobiles that are in salvage yards are there because of a crash - which activates part of the airbag system somewhere in the vehicle. What the salvage yards will not tell you is that the seat your buying probably has at least one component that will need to be replaced for air bag safety. In the 5th Generation ( and i believe before that ) the seat belt buckle receiver has what is called a pretensioner on it meaning when an accident is detected a small gas charge is activated that pulls the seat belt buckle downward - basically to activate the seat belt mechanism that prevents you from being able to move forward. Great safety feature but once that gas charged unit is fired you have to replace it. Once i replaced the two front seats i noticed the Air bag light on. Fortunately several years earlier i had purchased a check engine code reader that would also read air bag codes and that unit determined that both the passenger and Driver pretensioners (seat belt buckle receptacle) had to be replaced. To buy a new one is about $250 Canadian each. This is probably an expense someone is not thinking about when they are looking at upgrading their seats. You can tell if the pretensioner has been activated by looking to see if the buckle has collapsed slightly ( only an inch or so) Once these unit fire they have to be replaced ( there is a company in the USA that rebuilds them for about 80.00 US. ) Fortunately for us I was able to transfer the ones from the original seats over to these new seats and my air bag light is now out again. if your wondering what i am talking about I added some pictures. Below is two images the one with the blue arrow is a pretensioner that has been activated (fired) The one with the green check mark is normal.
