Service bulletin N242438850

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

Emission Recall - General Motors has decided to conduct a Voluntary Emission Recall involving certain vehicles equipped with a 3.6L engine. The joint that connects the high-pressure fuel pump’s outlet pipe to the pump may not have been welded within specified tolerances during the pump supplier’s manufacturing process. There is a potential that this weld joint is outside the tolerances that have been validated for the long-term durability of this pipe connection. Dealers are to replace the high-pressure fuel pump
