Automotive OEMs expect more than a form: they expect containment within days, evidence-based root cause and proof that the fix works. This guide covers what they actually check.
What OEMs expect
Interim containment reported fast — typically within 24 to 48 hours of notification.
A quantified problem statement with part number, lot, quantity, date code and detection point.
Root cause separated into technical cause, systemic cause and escape point.
Effectiveness evidence: measured data after implementation, not a statement of intent.
Documented horizontal deployment across similar products and lines.
Where IATF 16949 fits
The 8D report is the practical vehicle for the corrective-action requirements of IATF 16949 and customer-specific requirements. Auditors expect the report to connect to the control plan, FMEA and inspection standards that were updated as a result of D7.
