Failure to check and recheck wheel torques periodically until the torques remain constant from one inspection to the next.
Failure to maintain clean mating surfaces between the wheel, hub, and spacer surfaces and introducing additional runnout into the system which can lead to vibrations and subsequent wheel stud loosening issues.
Poor adapter design, especially the lack of torque rings/pockets around the wheel studs or bolt circle to aid in maintaining proper wheel stud torque/preload. If you want to see a well designed wheel adapter/spacer, refer to H&R Trak+ spacers.
Poor wheel spacer design and/or materials. Wheel spacers with multiple wheel patterns marketed as "universal" tend to also be die-cast from the least expensive aluminum and are prone to breaking due to unequal wheel torque, overloading, etc.
Lack of maintaining hub-centricity in applications where that is important...EB's not so much, however performance, high-speed applications tend to fall into this category.
The issues above tend to be the most common, however there are other issues like the use of press-in wheel studs with inadequate under-head surface area for use with aluminum, low-quality studs, etc that can also come into play. Properly designed, installed and maintained, I don't see any issues with the use of spacers or adapters, but that's true for so many of the modifications we do to our rigs.

Almost none of which are applicable to what I run without issue...well-designed well-made solid billet bolt-on wheel spacers. Of course they are not cheap..
