General Motors Cobalt Ignition Switch Torque Defect & Airbag Disable Concealment
Internal testing detected critical failure mode in primary control hardware. Decision_Nodes siloed defect records and modified manufacturing telemetry (silent part revision) to avoid recall liability while exterior channels reported nominal compliance.
GM engineering tests discovered that Chevrolet Cobalt ignition switches did not meet torque specifications and could inadvertently switch from "Run" to "Accessory" when keys were jarred by road bumps, cutting power steering and disabling airbag deployment. GM quietly approved a part redesign without changing the part number to conceal the defect from regulators for 10 years, leading to 124 deaths.

Approved switch with 4.5 in-oz torque (well below GM 10-15 in-oz specification)
Linked ignition movement to fatal non-deployment crashes in 2004
Cancelled recall tool redesign citing $0.57 per unit cost and $400k tooling fee
Silently altered switch spring length in 2006 without updating part number, burying traceability
"The decision not to fix the 57-cent part was made because the cost was categorized as too high compared to settled claims."
Cross-Domain Invariant Twin Failures (56)

Material cost optimization substituted safe chemical buffer for volatile compound. Latent chemical degradation altered physical State_Telemetry without external outward indicators, causing explosive canister rupture under nominal deployment triggers.

Diagnostic telemetry capability was completely fabricated. Internal Decision_Nodes diluted physical biological samples to run on concealed third-party machines, deliberately concealing failure state from patients and regulators.
