There does seem to be some evidence that other Coronaviruses may exhibit ADE but it's important to note that ADE is not well understood and that many viruses seem to display it in-vitro but non in-vivo.
In particular, vaccines and monoclonal antibodies targeted at SARS spike proteins seemed to cause ADE in some experiments but not in others.
There has also been at least one paper that speculated that the virus was deadlier in China than South Korea due to pre-existing exposure of the population so similar Coronaviruses and ADE cross-over from them. This was before the big spikes in mortality in Iran and Italy which would be pretty strong counter-evidence to this hypothesis.
I think it is best for us to treat our both our species-level understanding and our personal understanding of immunology and epidemiology (assuming that like me, you are reading papers but have not spent significant pre-existing time studying this field) with an appropriate level of epistemic skepticism. I would be careful of making statements like "a vaccine is unlikely to work" unless you have a high degree of confidence in your own understanding of the state-of-the-art.
(I haven't downvoted you and would encourage others not to do so as that mechanism is intended to remove noise and not to signal disagreement)
