General Motors Revises IATF 16949® Customer Specific Requirements Effective 1/1/23

General Motors IATF 16949® Customer Specific Requirements (CSR) revision dated December 22, 2022

General Motors (GM) has recently revised their customer specific requirements.  The latest revision is effective January 1, 2023. General Motors Customer Specific Requirements for IATF 16949 – January 2023

The revisions include the following:

  1. 3.3.1 Throughout the document: replaced: Risk Priority Number (RPN) with Risk Priority Levels (RPL)-writer’s note: this change was implemented to better align with the AIAG VDA FMEA approach
  2. 3.4.4 Corrected the referred document name: CG4338 GM 1927 03 Supplier Quality Statement of Requirements SOR
  3. 1.2.1-page 22 Replaced BIQS Requirements with GM Quality Performance Requirements and BIQS Level with Sourceability Level. Updated wording on GM Quality Performance Requirements (GM QPR) section/paragraph, including the Notes. Added a reference link to the Quick Reference Guide web page.  Deleted the word “quality” after NBH-this change is GM moving away from the BIQS level and moving toward the sourceability level (which is found in the sourceability report)
  4. 2.2.3 Added Brazing CQI-29 Brazing System Assessment and Rubber CQI-30 Rubber Processing System Assessment-writer’s note: additional CQI self assessments for applicable organizations

General Motors (GM) also recently revised the Quick Reference manual to include the changes (ie: description of the sourceability level on the sourceability report instead of BIQS level).  There is also an update to the GM suppliers’ certification body pre audit submission requirements that includes the following:

GM Scorecard – what performance data to use for audit pre-planning? (Rules 5.7.1 c)

  • Supplier Certification Management System (SCMS) Supplier Records screen confirming client name, manufacturing DUNS number and address.
  • Impact Detail Report indicating disruptions, product nonconformity incidents and details, Field Actions, New Business Hold records, including severity and supply chain SPPS (Supplier Practical Problem Solving) records.
  • Sourceability Report showing the Sourceability level.
  • CS 2 Notification Letters (emails) received since the most recent audit with associated corrective actions.
  • GM 1927 17 SQ Processes and Measurements Procedure showing metrics and status definition updates.

GM supplier focus

As a takeaway from these updates:

  1. BIQS levels will now be called sourceability levels, but will still be viewed on the sourceability report
  2. The move away from Risk Priority Number to Risk Priority Level is a consideration of the VDA AIAG FMEA methodology.
  3. The additional CQI assessments for Brazing and Rubber Processing may impact those suppliers that are involved with those processes (keep in mind these requirements are effective Jan 1, 2020)
  4. The pre audit data submission requirement include all five bullet points mentioned above. Your CB will be expecting data for all five points.

Certification Body focus

These changes take effective Jan 1, 2023 and the CB auditor will be required to audit to these changes when assessing the QMS of a supplier that supplies a GM manufacturing site.  Note: these requirements also apply to a lower tier supplier that is direct shipping to a GM manufacturing site.
