As far as I know, Wu-Yi Hsiang still maintains that his proof of the Kepler conjecture is complete and correct. Perhaps this does not quite meet your criteria because it seems that nobody other than Hsiang believes that his proof is complete and correct; is that enough agreement to use the word "consensus"?

In the introduction to his delightful anthology, 18 Unconventional Essays on the Nature of Mathematics, Reuben Hersh states, regarding the Flyspeck project of Thomas Hales, that he does not know anyone who either believes that the project will be completed or that, even if claimed to be complete, it will be universally accepted as definitively verifying the correctness of the proof. Of course, the completion of Flyspeck was announced in 2014. My impression is that most people accept that Flyspeck has settled the Kepler conjecture, but there are probably still some skeptics. Back in 2008, I had an email exchange with someone who pointed out that HOL Light is based on OCAML, and that the formal correctness of OCAML has not been established. It may be that there will always be a nontrivial minority of mathematicians who remain skeptical of results whose only proof is not "surveyable" or "humanly comprehensible," in which case such results may remain permanently controversial. (One could imagine that one day the Kepler conjecture will have a humanly comprehensible proof, but there will surely be other results, e.g., in extremal combinatorics, that are unlikely to have any proof other than an immense computer verification.)
