Component Failure & Inspection: Restraints Control Module (RCM) / physical airbags failed on a 2013 Lincoln MKZ. The 44-page Bosch CDR report proves a hardware failure: Page 8 logs a "YES" command for Frontal and Rollover Discriminating Deployment. System voltage was stable (14.02V at T0), and seatbelt pretensioners successfully fired (683.0 ms and 688.0 ms). However, physical airbags completely failed to inflate and left no execution timestamps. This matches NHTSA Campaign for 2013 Lincoln MKZ for air bag but owner was never alerted. NHTSA Campaign where cracked conformal coating shunts deployment voltage to ground. The vehicle/RCM are preserved and available for inspection.Safety Risk: The failure left driver K** ****** unprotected in a violent, multi-stage crash. Entering at 50.70 MPH, the vehicle braked to 40.02 MPH at initial impact struck car then struck the road and flipped ~1 second later. Due to non-deployment, the driver suffered severe injuries requiring critical medical air evacuation (airlift) and 6 months of lost wages so far. Confirmation/Reproduction: Confirmed via forensic data extraction. A retained professional pulled the black box data, generating a 44-page Bosch CDR report proving the software commanded deployment ("YES") but the hardware mechanically failed.Inspections: The Louisiana Uniform Crash Report explicitly notes "Not Deployed" despite the rollover. State Farm Insurance reviewed these digital metrics and reassigned 100% fault to the other driver
