Can Autofac cause memory leaks?

Singletons

Autofac uses strong reference to hold onto singleton components. This objects will exist at least for as long as Autofac container exists.

Factory scoped

Factory scoped components that are owned by the container are held using weak references, so that they can be disposed at the appropriate time or earlier in the case that they can be garbage-collected.

Factory scoped components with external ownership are not referenced by Autofac at all - the reference returned from Resolve() will be the only reference at that point.

Autofac should never cause memory leaks. For more information on tracking down leaks in .NET see Memory Leak Detection in .Net article

Deployment
