Service bulletin 20TS-06

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

DDC Technical Service Letter for GHG17 DD Platform Heavy Duty Oil Pan Drain Plug Inserts. Some GHG17 DD Platform Heavy Duty oil pans may experience an issue with the oil pan drain plug insert spinning during removal or installation while completing an oil change. Leaking may also be observed at the drain plug and/or other plugs in the oil pan.

Engine, Equipment and accessories

Listing a model year does not mean every vehicle of it is concerned: the document says which.

A recall listed here may apply to some of the same vehicles. Only the manufacturer can say whether it applies to one vehicle.
