This PI will cover the engine exchange program onlyfor the 2019 model listed above.

Additional PIs will be published for each engineor component as they are introduced.

During the launch of the 2019 model yea,rthe following engine will beunder an exchange program:
2.7L Engine Assembly (RPO L3B)

Product teams continually seek valuable information for engineering improvements.

To assist in this effort, an engine exchange program will be used for the listed engine and vehicles

The 2019 model year engine exchange program will be administered by the GM Product Quality Center
(PQC).

Dealerships are required to call the PQC, not GM eTchnical Assistance (TAC), to request an
exchange.

Prior to calling the PQC, please make sure to complete the “OEM Engine Exchange” template in this
PI.

Use of the templates will minimize the time spent on the telephone and avoid the need of a secon
call to the PQC.

Guidelines for honoring exchange requests under this program are being strictly enforced.

The PQC may refer the dealer technician to TAC if additional diagnosis is required. TAC will be
available for product inquiries that do not require assembly replacement.

Division PQC Telephone Number

Components that may be removedand serviced withoutexchange are identified by an “X” in the
appropriate column of the table below.

Any repairs involving engine components not identified in the table belo,wengine noise concerns, oil
consumption, or relatedsymptoms may require an engine exchange.

Important: Engine block and internal components along with any component in which a cylinder head
has to be removed to performthe repair will require an engine exchange.

Please note that this list is subject to change as the program progresses.

You will be notified by the PQC consultant if additional items are considered serviceable on a
particular engine.

Important: Engine repairs or failures that are causedby components external to the engine do NOT
fall under the exchange program. For example, if an engine failure is caused byincorrectly
installed engine coolant lines, the engine assembly (or parts required to complete a repair) must
be obtain from General Motors Customer Care and Aftersales (GMCC&A) through the normal parts
ordering process. The exchange programis created as a way to correct internal concerns and to take
what is learned and find a way to eliminate these concerns. Externalcomponents causing a failure do
not provide any useful information in improving an engine. The engine received from GMCC&tAhrough
the normal parts ordering process will be a new service engine.
