For low level programming in general:

1. real time issues/performance
2. unpredictable cleanup (finalization/RAII)
3. higher memory consumption
4. more challenging interop with other languages
5. cannot be used in some execution contexts

For D specifically:
1. freezing all GC threads
2. no tracking of ownership-type in the type system
