Bulletin Summary
Engine fuel filters (part number 21380521) with week number date codes ?15_33? (August 10, 2015) through ?15_39? (September 27, 2015) should not be installed on an engine without first being inspected. The week number date code is marked on the outside of the filter, the number on top is the year and the number below identifies the week. Due to a manufacturing issue, fuel does not flow through the filter which results in a no-start/run condition immediately after installation.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
