2017 Buick LaCrosse Air Bags

The air bag warning light in the dash came on intermittently during driving. I took the vehicle to the dealer for service December 27, 2023, since it was a safety issue that the authorized dealer needs to take care of. At first, they said it was a bad battery and the safety system needed reprogramming. Which they did for about $800. When driving home from the dealer the air bag light came back on so a few days later I returned the car to the dealer. Then they said it was the passenger seat safety module that needed to be replaced. That was back in January of 2024, over 6 months ago. At that point I learned that the car is not drivable since the air bag could deploy at any time or would not function if requested in an accident. General Motors says they do not have the part that is critical to the operation of the air bag system to replace. That was over 6 months ago, with no prediction when they will have the part. This is a critical part of the safety system that they can't replace which leads me to believe there is more to this than they are telling me!! Federal law requires them to have parts for vehicles less than 7 years old - they don't!! How many other vehicles have this part? Is the part defective since it failed without any other causes that could be identified? Why can't they replace this critical safety part after 7 months of waiting with no end in sight!!!

the airbag lite has been coming on for the last year saying it needs to be serviced. I have had it to the buick dealer for 4 times this last year and they still can not of will not fix it.The airbag lite comes on when we turn the steering wheel to the left.The last time I had it in was March of this year.When we left with the car the first left hand turn I made it came on.I am tired of fooling with it.after they work on it I told them to take it for a trail drive thye did not.
