How is a PRR different from an 8D?

A PRR is GM's tracking system for the supplier quality event. An 8D is the corrective action report format used to respond to the PRR. One PRR typically requires one 8D submission for closure.

How long do PRRs typically stay open at GM?

PRR closure targets vary by severity but typically 30 to 45 days for standard issues and 15 to 21 days for higher-severity events. Suppliers with on-site plant presence typically close in the first half of these windows.

Can suppliers negotiate PRR containment scope with the plant?

Yes, within the first week of PRR issuance. Suppliers proposing narrower scope (specific shifts, specific operations, alternative inspection methods) within days often succeed. Pushback after scope is set rarely succeeds.

What triggers a PRR to escalate to Controlled Shipping?

Repeated PRRs on the same or similar defect modes, failure to close PRRs within customer target windows, or a major escape event. Typically 3 to 4 pattern PRRs in a 6-month window can trigger CS1 discussion.

How can IDS help with active PRR response?

IDS provides same-day on-site PRR response at GM Spring Hill, Ford, Stellantis, and Ultium Cells facilities. Common engagements include containment coordination, customer-facing communication, 8D preparation support, and closure verification.

Key Takeaways

GM PRR (Problem Resolution Report) is the formal escalation tracking system for supplier quality events. PRR closure cycle time is a scorecard metric that directly affects supplier rating.

First 72 hours after PRR issuance determines closure cycle: same-day acknowledgment, on-site presence within 24 to 48 hours, containment plan documented within 72 hours.

PRRs stay open until customer SQE confirms closure. Slow closure compounds scorecard impact even when the technical corrective action is complete.

Common closure failures: verification data too thin (D6), containment scope under-scoped, root cause too shallow, or communication cadence too slow.

Suppliers with regular on-site plant presence close PRRs materially faster than suppliers responding remotely. This is the strongest lever for scorecard improvement.

A GM Problem Resolution Report (PRR) has just been issued against your part number. The plant quality contact has opened the formal escalation. Your supplier scorecard begins accumulating the impact. The next 72 hours determines whether this closes as a routine event or drags on for weeks as a scorecard problem.

This guide covers exactly how to respond to a PRR, what closure velocity looks like in 2026, and how to prevent PRRs from compounding into pattern issues that trigger Controlled Shipping. For emergency PRR response support, contact IDS at 905-260-2388.

What a PRR Actually Is

PRR (Problem Resolution Report) is GM's formal supplier quality event tracking system. It parallels Ford's GIR and Stellantis's TSV. When a plant quality contact issues a PRR, it enters the GM supplier quality database, begins accumulating scorecard impact, and stays open until the customer SQE confirms closure.

The First 72 Hours

Hour 0 to 4: Acknowledge and Assess

Same-day acknowledgment of the PRR notification to the plant quality contact. This is a written response, not a phone call. Establishes the supplier response tree and next-update commitment. See our first hour playbook.

Hour 4 to 24: Deploy On-Site

On-site presence at the customer plant within 24 hours for material events. This is where PRR closure velocity is actually decided. Suppliers responding remotely close PRRs 2 to 3 times slower than suppliers with on-site presence.

Hour 24 to 72: Containment Plan Documented

Written containment plan submitted to plant quality contact within 72 hours. Includes specific gauges, criteria, dates, and effectiveness verification approach. See containment management guide.

PRR Closure Sequence

Containment complete: All suspect material inspected, quantities reported to customer
Root cause identified: Documented via 5 Why or similar analysis, verified with data
Permanent corrective action implemented: Process change in place, control plan updated
Verification data collected: Statistically meaningful sample sizes demonstrating fix effectiveness
Read-across analysis complete: Similar processes and programs assessed for the same failure mode
8D report submitted: Ford Global 8D format equivalent for GM programs, D1 through D8 complete
Customer SQE closure confirmation: Formal PRR status change in the GM system

Common PRR Closure Failures

D6 verification too thin: Three days of clean shipments is not verification. Statistically meaningful sample sizes required.
Containment scope under-scoped: Missing supplier dock, in-transit, or customer dock coverage produces re-escapes.
Root cause too shallow: "Operator error" is not root cause. 5 Why analysis must reach systemic factors.
Communication cadence too slow: Silence between customer contact and closure signals disengagement.
No read-across analysis: Fixing the specific defect without checking similar programs invites repeat PRRs.

Preventing PRRs from Compounding

Two or three unrelated PRRs in a rolling 6-month window trigger GM SQE elevated scrutiny. Four or more in the same window can trigger Controlled Shipping Level 1 (CS1). See our Controlled Shipping guide.
