Bulletin Summary
Special Coverage. Certain vehicles equipped with a 6.6L diesel engine (RPO L5P), may have a condition that could cause the engine glow plugs to fail. If this condition occurs, the Malfunction Indicator Light (Check Engine Light) will illuminate and a diagnostic trouble code will set. Additionally, the engine may be hard to start or the engine may run rough immediately following engine start. Dealers are to replace the glow plugs as necessary. The repairs will be made at no charge to the customer.
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.
