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.
