The most common problem with the 2008 Buick Lucerne with the Northstar V8 are the same as all the other Northstar V8s cars, and that is a failed head gasket. The Northstar has a very big reputation for blowing head gaskets, and damaged head studs. When a head gasket fails in Your car it allows the engine oil and coolant to mixAnd that can cause the engine to completely fail and seize up. There are kits on the market that can help fix this problem though. Usually to fix the problem You will need to install a new head stud kit on the engine and then install new gaskets. This can prevent them from failing.
