General Motors Cobalt Ignition Switch Torque Defect & Airbag Disable Concealment

Incident Failure Topology Brief
Catastrophic (Level 5)Sev 9.8/10

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.

Failure Invariant Breach
Deliberate telemetry concealment
Absent Safety Recovery Mechanism
Mandatory direct whistle-blower escalation path to federal safety regulators
Domain De-Aliasing & Jargon Stripping
Raw Domain Record (Subjective Narrative)

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.

STEP 01DEGRADE
Switch_Engineering

Approved switch with 4.5 in-oz torque (well below GM 10-15 in-oz specification)

Vector: Defective constraint design

Crash_Analysis_Team

Linked ignition movement to fatal non-deployment crashes in 2004

Vector: Early failure discovery
STEP 03DEGRADE
Program_Management

Cancelled recall tool redesign citing $0.57 per unit cost and $400k tooling fee

Vector: Incentive misalignment
STEP 04RUPTURE
Parts_Supplier

Silently altered switch spring length in 2006 without updating part number, burying traceability
