Quality is the factor of the production equation that can go to zero overnight. A plant can have a product customers want, full lines and a sound balance sheet, and still destroy its value with one escape: a door plug reinstalled without its four bolts on a ten-week-old Boeing 737 MAX 9 (Alaska Airlines Flight 1282, 5 Jan 2024), after which the FAA capped 737 output at 38 a month and allowed 42 only in Oct 2025; an airbag propellant that degraded with heat, humidity and age, which turned Takata into the largest auto recall in US history (~67m inflators in ~42m US vehicles) and a guilty plea; an ignition switch that General Motors knew was weak for years before its 2014 recall. Quality failures are also routine: US carmakers file hundreds of safety recalls a year with NHTSA, and in 2025 Ford alone filed a record ~152–153 campaigns covering ~12.9m vehicles — more vehicles than the next nine manufacturers combined (NHTSA data via press tallies, Dec 2025–Jan 2026; the previous single-company record was GM's 77 campaigns in 2014, reported). In Europe, Stellantis booked a €4.1bn warranty-provision change in its Feb 2026 reset, which management attributed to quality problems, and Volkswagen's 2015 diesel defeat device showed that measurement itself can be the defect. This section explains how quality is measured and costed, the systems and standards that make it repeatable (APQP, PPAP, FMEA, ISO 9001, IATF 16949, AS9100, ISO 13485), the US recall regimes (NHTSA, CPSC, FAA, FDA) and their European counterparts, the landmark failures, product liability and mass torts, and how to read a company's quality claims. Two companion files give a worked example of what a quality escape costs and when a recall beats waiting, and a supplier-quality audit checklist.

Quality Escape Expected Cost and Recall Timing Worked Example
A stylized supplier's escape priced at each detection point (station to field, with good and poor traceability), then a monthly model of when recalling 300,000 vehicles beats waiting, across failure patterns, remedy capacity, severity, penalties and completion rates (computed in Python)
Supplier Quality Audit Checklist
Questions and evidence for auditing a supplier: certification, APQP and PPAP, change control, process control, measurement, problem solving, traceability and recall readiness, people, financial health, data integrity

Medical-device recalls and companies (Philips Respironics, Medtronic, Abbott) are covered in Healthcare: 07 Medical Devices, Diagnostics and Labs and Healthcare: Philips; Toyota's 2009–10 recalls are told from the supply-chain side in Supply chain: Toyota. The main book's Appendix A computes OEE and the cost of downtime, including the scrap lost to poor first-pass quality; this section's worked example is about escapes that reach customers.
