## 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
