Affected vehicles are identified in OASIS.
Note: Some vehicles may have been repaired or are in the process of being repaired at the assembly
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 Attachment II for
more information.
New! REASON FOR PROVIDING A NO-COST, ONE-TIME REPAIR
Dealers must complete the engine valve inspection test for safety recall 24S55 on affected vehicles.
This program provides coverage for a long block engine replacement should a customer require it
after 24S55 has been completed. Engine replacement is covered if part of the engine valve has
broken off and dropped into the cylinder causing engine failure, as described in 24S55.
SERVICE ACTION
If an affected vehicle exhibits an engine valve failure concern and has completed 24S55, dealers are
to contact the SSSC for specific instructions on how to verify this engine failure is related to FSA
24S55. This service must be performed at no charge to the vehicle owner. For new vehicle storage
guidelines, refer to EFC13033, Storage Guidelines for New Vehicles.
