On December 22nd, General Motors published their updated IATF 16949 Customer Specific Requirements, with the new CSR taking effect on January 1, 2023. The full table of changes is in the image below.

Aside from the replacement of BIQS requirements with GM Quality Performance Requirements, the most noteworthy change is the note: “Throughout the document: replaced: Risk Priority Number (RPN) with Risk Priority Levels (RPL).

In 8.3.3.1, the CSR states: “Risk Priority Levels (RPL) shall be consistently applied using Severity, Occurrence, and Detection ranking tables, and the RPL nomenclature shows up elsewhere throughout the document. While General Motors hasn’t gone as far as Ford in requiring the use of FMEA software and Foundation FMEAs in their latest CSR, this also appears to be posturing to prepare for the move from RPN to the use of the more robust tables for Action Priority that we see in the harmonized AIAG/VDA FMEA handbook. We’ve reached out to a representative at General Motors for comment but have not yet received a response at the time of publication.
