This PI will cover the engine exchange program only for the 2019 model listed above.
Additional PIs will be published for each engine or component as they are introduced.
During the launch of the 2019 model year, the following engine will be under an exchange program:
6.6L Diesel Engine (L5D)
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 contacted the PQC, not GM Technical Assistance (TAC), to request an exchange.
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.

Canada — English and French
Components that may be removed and serviced without exchange are identified by an “X” in the appropriate column of the table below.
Any repairs involving engine components not identified in the table below, engine noise concerns, oil consumption, or related symptoms 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 perform the 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 caused by components external to the engine do NOT fall under the exchange program. For example, if an engine failure is caused by incorrectly installed engine coolant lines, the engine assembly (or parts required to complete a repair) must be obtained from General Motors Customer Care and Aftersales (GMCC&A) through the normal parts ordering process. The exchange program is created as a way to correct internal concerns and to take what is learned and find a way to eliminate these concerns. External components causing a failure do not provide any useful information in improving an engine. The engine received from GMCC&A through the normal parts ordering process will be a new service engine.
