NHTSA Complaint #11513115 — 2016 TESLA MODEL X

My 2016 model X has been experiencing front passenger and rear passenger safety restraint system faults off and on since we purchased the vehicle in 2019. This notification requires service and the Tesla service center has done a mixture of hardware checks, replacement of parts and keeps blaming the issues on a firmware update that will eventually happen in the future. Tesla says that when the system is tripped the airbags may not deploy and to schedule service when it happens. Because the vehicle is under a used warranty they refuse to address this as a recall or possibly defect.
