Dealers Required to Contact the PQC —
PQC Process
The following is a step by step process for dealers
required to contact the PQC prior to assembly
replacement:
1. If an engine “noise” is involved, the technician
should attempt to capture that noise on a
30 second Sound File prior to disassembling the
engine.
2. Complete the disassembly and diagnosis. This
includes OEM calibration verification number as
outlined in applicable service bulletins.
3. Complete the Cost Comparison Worksheet.
Accurate repair vs. replacement cost estimates
(include the markups) are essential for prompt
handling of your PQC case.
If an assembly is replaced per direction from TAC
due to a known product issue, or per authorization
from a Brand Quality Manager (BQM) or a Field
Service Engineer (FSE), complete all of the
information at the top of the Cost Comparison
Worksheet, documenting the TAC case (if
applicable) and/or BQM or FSE involvement (if
applicable). In the Cost Comparison section,
estimates for “Repair” do not need to be
completed. Complete the costs associated with the
replacement of the assembly only.
4. If diagnosis and cost analysis indicate a need for
assembly replacement, then the PQC must be
contacted prior to assembly replacement.
• United States Dealers Only. Perform the
following:
– Contact the PQC by opening a new case via
Dealer Case Management (DCM). From the
DCM home page, click on “New PQC Case”
found on the Technical Assistance tab.
– Provide all required information. Be prepared to
include the following information: job card
number, VIN, mileage, how many times the
vehicle has been in for the concern, and number
of days down. Additional comments should
include if there are any vehicle alterations or
aftermarket parts, and if the concern has been
duplicated by your dealership.
– Once you have saved the information, a case
number will be created. Note the case number on
the job card.
– Once the case is created, click on the case
number to open it and attach the completed Cost
Comparison Worksheet.
– Attach pictures (.jpg files) showing the point of
failure. This is not required for assemblies on
part restriction or part of an exchange program.

part of Step 1. This is not required for assemblies
on part restriction or part of an exchange
program.

BAC, job card number, VIN, mileage and an
explanation in the email of why an assembly
replacement is necessary.

– Attach pictures (.jpg files) showing the point of
failure. This is not required for assemblies on
part restriction or part of an exchange program.
– Attach any engine noise sound files captured as
part of Step 1. This is not required for assemblies
on part restriction or part of an exchange
program.
5. The PQC and TAC will review the case to
determine if an assembly replacement is
appropriate. To submit additional information or
follow up on a case, call the PQC at
1-866-654-7654. Be prepared to provide the PQC
the case number (if available) and your BAC code.
– If the assembly replacement is not agreed to,
then proceed with repair of the assembly.
– If the engine or transmission assembly
replacement is agreed to based on information
provided by the Dealer Service Personnel, then
proceed with the replacement.
– Once a determination to repair or replace has
been made, further calls/emails to the PQC are
not necessary.

assembly replacement transaction, follow these
steps:
6.1. Scan the shop copy of the job card and attach
it to the transaction.
6.2. Scan the completed Cost Comparison
Worksheet and attach it to the transaction.
6.3. Route the transaction for GM authorization (H
route) to the Warranty Support Center (WSC)
for processing.
Important: Agreement from TAC or PQC (based on
the information provided by the Dealer Service
Personnel) to replace an assembly does not
constitute final determination that the transaction
meets all Service Policy and Procedure
requirements. General Motors reserves the right to
