Service bulletin GCUS-3-293

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

15532 - Service Update. This bulletin provides a service procedure to correct a potential oil leak on certain 2015 model year Buick Enclave, Chevrolet Traverse and GMC Acadia vehicles equipped with a HFV6 engine (RPO LLT). The potential leak is from the oil pan crank case at an engine mount hole location, which is not under engine oil system pressure. To correct this condition, dealers will remove the mounting bolt, clean the bolt and hole, apply thread sealant and reinstall the bolt.
