PROGRAM TERMS
This program will be in effect through October 31, 2026. There is no mileage limit for this program.
URGENCY / EXPIRATION DATE
This Customer Satisfaction Program has an expiration date of October 31, 2026, to encourage
dealers and customers to have this service performed as soon as possible.
We recommend dealers utilize their FSA VIN Lists name and address to contact customers with
affected vehicles. This will help minimize the number of vehicles that may experience engine coolant
leaks or engine failure, which may require towing. FSA VIN Lists are expected to be available on
October 26, 2023.

U.S. population of affected vehicles: 131. Affected vehicles are identified in OASIS and FSA VIN Lists.
Note: Some vehicles may be in the process of being repaired at the plant. Monitor OASIS before
opening an RO and/or beginning a repair. Parts purchased for an FSA can be returned for credit if
required. See the EXCESS STOCK RETURN details in Labor Allowances and Parts Ordering
Information for more information.
REASON FOR THIS PROGRAM
In the affected vehicles, a damaged tool used during the engine block
casting process may lead to the
formation of a crack in the right side of the engine block
assembly that can result in a coolant leak.
Customers may experience a progressive series of symptoms, including a low coolant pressure,
which could lead to a coolant leak that would be visible beneath the vehicle and finally may result in
an illuminated Service Engine Soon Indicator for an engine overheat condition.
SERVICE ACTION
Dealers are to replace the engine long block (Base Part # 6006) assembly. This service must be
performed on all affected vehicles at no charge to the vehicle owner.

OWNER NOTIFICATION MAILING SCHEDULE
