My Airbag Readiness Light started blinking. I took vehicle to dealer for service. No trouble codes were found. Issue was found with Passenger Presence Module. Dealer advised that this is part of the seat that has been discontinued and that no repairs are available for the vehicle. I found a GM Engineering Information bulletin on your website that states the exact conditions that I am seeing with my vehicle. It instructs Technicians to replace two modules and two sensors and to send the old parts to GM Engineering for root cause analysis. But apparently, these parts have been discontinued. I now have a vehicle in which the airbag protection system may not work properly, especially to protect an occupant in the passenger seat, and there is no fix. I don't understand how a vehicle that is only six years old cannot have parts to make repairs.
